Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to an information processing method and apparatus. Background Technology

[0002] To cope with the explosive growth of mobile data traffic, massive device connections, and the continuous emergence of new services and application scenarios, the 5th-Generation (5G) mobile communication system will emerge. As a component of 5G, the Internet of Things (IoT) is experiencing rapid market demand growth; forecasts indicate that the number of 5G IoT connections will reach 18 billion by 2022.

[0003] Currently, solutions for the characteristics of the Internet of Things (IoT) include Narrow Band – Internet of Things (NB-IoT) networks and Machine Type Communication (MTC) networks. NB-IoT leverages the characteristics of narrowband technology to carry IoT services. NB-IoT networks utilize a new air interface technology independent of cellular networks, resulting in lower terminal costs but supporting lower speeds and mobility. MTC networks possess some characteristics of cellular networks, but MTC network terminals have slightly higher costs and complexity than NB-IoT network terminals. However, MTC network terminals can support higher speeds and better mobility.

[0004] Currently, both NB-IoT and MTC networks are commercially available, but new application scenarios require technical solutions, such as wake-up signal characteristics that reduce terminal listening and paging power consumption. There is an urgent need for a new information processing method to adapt to the needs of these new application scenarios in NB-IoT and / or MTC networks. Summary of the Invention

[0005] This application provides an information processing method and apparatus that can transmit configuration information for wake-up signals, enabling terminal devices to save paging power consumption and improve network resource utilization by listening to wake-up signals.

[0006] In a first aspect, embodiments of this application provide an information processing method, comprising: a network device determining configuration information of a wake-up signal, the wake-up signal being used to indicate whether to page a terminal device within a certain period of time, the configuration information of the wake-up signal being used to indicate the time interval between two adjacent wake-up signals (including the time interval between possible locations of the two wake-up signals); and the network device sending the configuration information of the wake-up signal to a core network device.

[0007] In this embodiment, the wake-up signal is used to indicate whether to page the terminal device within a certain period of time, the value of which can be determined by the network device. The wake-up signal is mainly used for terminal devices with very short paging cycles but a low probability of being paged. The terminal device will only wake up to receive paging messages when it hears the wake-up signal. If it does not receive a wake-up signal, the terminal device will not listen for paging messages from the network device until it hears a wake-up signal indicating that the terminal will be paged. The configuration information of the wake-up signal is used to indicate the time interval between two adjacent wake-up signals; the implementation method of this configuration information is not limited.

[0008] It should be noted that, in this application, the configuration information of the wake-up signal is used to indicate the time interval between two adjacent wake-up signals, or the configuration information of the wake-up signal is used to indicate the time interval between two consecutive wake-up signal detections by the terminal device. For example: the wake-up signal can have two states. State 1: The network device sends a wake-up signal indicating that it needs to wake up the terminal device; if the network device does not send a wake-up signal, it indicates that the terminal device will not be woken up. State 2: The wake-up signal has two or more states; state 1 (e.g., 01) indicates that the terminal device will be woken up, and state 2 (e.g., 10) indicates that the terminal device will not be woken up.

[0009] For example, a wake-up signal indicates whether a terminal device will be paging you within a certain period of time. Any signal that can serve a wake-up function can be considered a wake-up signal. For instance, the presence or absence of a signal can indicate whether paging will occur within a future period. If a terminal device at a specific location detects a wake-up signal, it means the network device will send a paging message. If no wake-up signal is detected, it means there will be no further paging messages until the terminal device tries to detect the wake-up signal again at the next signal location. Alternatively, different states of the wake-up signal can indicate whether there will be further paging messages within a future period. If a terminal device detects a specific signal state at a specific location, such as 01, it means a paging message is imminent. If another state is detected, such as 10, it means there will be no further paging messages. In this embodiment, the wake-up signal can reduce the listening overhead of a terminal device monitoring traditional paging. Because the wake-up signal is relatively simple, monitoring it saves resources compared to monitoring the PDCCH in traditional paging. If the terminal device is not being paged, it only listens for this wake-up signal, thereby saving network resources.

[0010] As illustrated by the foregoing embodiments, in this application embodiment, the network device can determine the configuration information of the wake-up signal. The wake-up signal indicates whether to page the terminal device within a certain period of time, and the configuration information indicates the time interval between two adjacent wake-up signals. The network device sends the configuration information of the wake-up signal to the core network device. The core network device can receive the configuration information of the wake-up signal from the network device. Therefore, this application embodiment can realize the transmission of the wake-up signal configuration information. After receiving the configuration information of the wake-up signal, the core network device can complete the paging configuration of the terminal device based on the configuration information, so that the terminal device can save paging power consumption by listening to the wake-up signal and improve the utilization rate of network resources.

[0011] In one possible design of the first aspect, the configuration information of the wake-up signal includes at least one of the following: information indicating the period of the wake-up signal, information indicating the correspondence between the wake-up signal and discontinuous reception DRX periods, or information indicating the duration. Specifically, the information indicating the period of the wake-up signal can be the period information of the wake-up signal itself, or other information capable of determining the period value of the wake-up signal. The information indicating the correspondence between the wake-up signal and the DRX period can specifically be information indicating the correspondence between the wake-up signal and the DRX period. For example, the correspondence between the wake-up signal and the DRX period can be a value indicating how many DRX periods correspond to one wake-up signal. For example, the letter 'x' represents the number of DRX periods corresponding to one wake-up signal, and the value of 'x' can be a positive integer such as 1 or 2. The information indicating the duration is a value indicating whether the wake-up signal needs to page the terminal device within a certain duration. For example, if the duration represents 3 subframes, then the wake-up signal needs to page the terminal device within 3 subframes. In this embodiment, the usage threshold of the wake-up signal refers to the eDRX period threshold for using the wake-up signal. The unit of this usage threshold can be a time unit such as seconds or milliseconds, or it can be a time slot, subframe, system frame, superframe, etc., that can reflect time. In this application, time slots, subframes, system frames, or superframes are examples of one or more time units. It is understood that, unless specifically emphasized, the examples of time units given in this application can be replaced with other time units, such as subframes can be replaced with time slots.

[0012] In one possible design of the first aspect, the configuration information of the wake-up signal further includes: information indicating the start position and duration of the wake-up signal within a period. The start position and duration of the wake-up signal within a period can be considered as configuration information for the wake-up signal. The start position indicates the position where the wake-up signal begins to be transmitted within a period, and the duration indicates the number of units of time (also called time units, such as symbols, time slots, or subframes) occupied by the wake-up signal within a period. By indicating the start position and duration of the wake-up signal within a period, the signal configuration parameters of the wake-up signal can be described more accurately.

[0013] In one possible design of the first aspect, the method further includes: the network device sending information indicating the DRX period to the core network device. The DRX period can be configured by the base station, and each terminal device has one paging opportunity within a DRX period. The information indicating the DRX period can specifically be configuration information for the DRX period, or other information that can determine the DRX period value. The network device sending the information indicating the DRX period to the core network device enables the core network device to obtain this information, thereby allowing the core network device to obtain the DRX period value parameters based on this information.

[0014] In one possible design of the first aspect, the network device sends configuration information for a wake-up signal to the core network device, including: the network device sending an interface establishment request message to the core network device, the interface establishment request message carrying the configuration information for the wake-up signal; or, the network device sending a configuration update message to the core network device, the configuration update message carrying the configuration information for the wake-up signal. The interface establishment request message refers to the request message sent by the network device when establishing an interface between the network device and the core network device. The configuration information for the wake-up signal is carried through this interface establishment request message; for example, a new field can be added to the interface establishment request message to carry the configuration information for the wake-up signal, or an expandable field in the interface establishment request message can be used to carry the configuration information for the wake-up signal. The network device's configuration update message indicates a notification message sent by the network device to the core network device when there is a configuration update.

[0015] Secondly, embodiments of this application provide an information processing method, including: a core network device receiving configuration information from a wake-up signal from a network device, wherein the wake-up signal is used by the network device to indicate whether to page a terminal device within a certain period of time, and the configuration information is used to indicate the time interval between two adjacent wake-up signals (including the time interval between possible locations of the two wake-up signals).

[0016] As illustrated by the foregoing embodiments, in this application embodiment, the core network device can receive configuration information of a wake-up signal from a network device. The wake-up signal indicates whether to page the terminal device within a certain period of time, and the configuration information indicates the time interval between two adjacent wake-up signals (including the time interval between possible positions of the two wake-up signals). Therefore, this application embodiment can realize the transmission of wake-up signal configuration information. After receiving the wake-up signal configuration information, the core network device can complete the paging configuration of the terminal device based on the configuration parameters, enabling the terminal device to save paging power consumption by listening to the wake-up signal and improve the utilization rate of network resources.

[0017] In one possible design of the second aspect, the method further includes: the core network device determining the paging time window (PTW) length of the terminal device based on the configuration information of the wake-up signal, wherein the PTW length is greater than the time interval between two adjacent wake-up signals. Specifically, the core network device can determine the PTW length of the terminal device based on the configuration information of the wake-up signal. Since the PTW length determined by the core network device is greater than the time interval between two adjacent wake-up signals, and the wake-up signal is sent periodically, there are more than one wake-up signal within one PTW. This avoids the paging delay caused by having to wait for the next eDRX cycle due to missing a wake-up opportunity, thereby improving the utilization rate of network resources.

[0018] In one possible design of the second aspect, the core network device receives configuration information of a wake-up signal sent by the network device, including: the core network device receiving an interface establishment request message from the network device, the interface establishment request message carrying configuration information of the wake-up signal; or, the core network device receiving a configuration update message from the network device, the configuration update message carrying configuration information of the wake-up signal. Specifically, the core network device can receive the interface establishment request message from the network device, which is a request message sent by the network device when establishing an interface between the network device and the core network device. This interface establishment request message carries the configuration information of the wake-up signal; for example, a new field can be added to the interface establishment request message to carry the configuration information of the wake-up signal, or an expandable field in the interface establishment request message can be used to carry the configuration information of the wake-up signal. The core network device can also receive the configuration update message from the network device, which indicates a notification message sent by the network device to the core network device when there is a configuration update. For example, a new field can be added to the configuration update message to carry the configuration information of the wake-up signal, or an expandable field in the configuration update message can be used to carry the configuration information of the wake-up signal.

[0019] In one possible design of the second aspect, the configuration information of the wake-up signal includes information indicating the period of the wake-up signal. The core network device determines the paging time window (PTW) length of the terminal device based on the configuration information of the wake-up signal, including: the core network device determines the PTW length based on the period of the wake-up signal, and the PTW length is greater than the value of the period of the wake-up signal. Specifically, the core network device determines the PTW length based on the value of the period of the wake-up signal, and the PTW length determined by the core network is greater than the value of the period of the wake-up signal. For example, the PTW length can be greater than or equal to 'a' times the value of the period of the wake-up signal. Thus, there can be more than 'a' wake-up signals within one PTW length. The value of 'a' can be a positive integer. For example, when the value of 'a' is 2, the core network device calculates that there are 2 wake-up signals within the PTW length. Similarly, when the value of 'a' is 3, the core network device calculates that there are 3 wake-up signals within the PTW length.

[0020] In one possible design of the second aspect, the configuration information of the wake-up signal includes information indicating the correspondence between the wake-up signal and discontinuous reception DRX cycles. The core network device determines the paging time window (PTW) length of the terminal device based on the wake-up signal configuration information, including: the core network device determining that the correspondence between the wake-up signal and the discontinuous reception DRX cycles is: one wake-up signal corresponds to x DRX cycles, where x is a positive integer; the core network device determines the PTW length based on the correspondence between the wake-up signal and the discontinuous reception DRX cycles, and the PTW length is greater than the result obtained by multiplying x by the value of the DRX cycle. Specifically, the core network device determines the PTW length based on the correspondence between the wake-up signal and the discontinuous reception DRX cycles, where one wake-up signal corresponds to x DRX cycles, and x is a positive integer, for example, x is 2. The PTW length determined by the core network is greater than the result obtained by multiplying x by the value of the DRX cycle. For example, the PTW length can be greater than or equal to 'a' multiplied by 'x', then multiplied by the DRX period value. 'x' multiplied by the DRX period corresponds to one wake-up signal. Thus, within one PTW length, there can be more than 'a' wake-up signals. The value of 'a' can be a positive integer. For example, when 'a' is 2, the core network device calculates that there are 2 wake-up signals within the PTW length. Similarly, when 'a' is 3, the core network device calculates that there are 3 wake-up signals within the PTW length.

[0021] In one possible design of the second aspect, the configuration information of the wake-up signal includes information indicating the duration. The core network device determines the paging time window (PTW) length of the terminal device based on the configuration information of the wake-up signal, including: the core network device determines the PTW length based on the duration information, and the PTW length is greater than the duration value. Specifically, the core network device determines the PTW length based on the duration value of the wake-up signal, and the PTW length determined by the core network is greater than the duration value of the wake-up signal. For example, the PTW length can be greater than or equal to 'a' times the duration of the wake-up signal. Thus, there can be more than 'a' wake-up signals within one PTW length, where 'a' can be a positive integer. For example, when 'a' is 2, the core network device calculates that there are 2 wake-up signals within the PTW length. Similarly, when 'a' is 3, the core network device calculates that there are 3 wake-up signals within the PTW length.

[0022] In one possible design of the second aspect, the method further includes: the core network device sending a paging message to the network device, the paging message including: an extended discontinuous reception eDRX cycle. Specifically, the core network device can send the determined eDRX cycle of the terminal device to the network device, enabling the network device to receive the eDRX cycle. The network device can then compare the eDRX cycle with a wake-up signal usage threshold to determine the magnitude relationship between the two, and then determine whether to use the wake-up signal.

[0023] In one possible design of the second aspect, the method further includes: the core network device sending information indicating the PTW length to the terminal device; and / or, the core network device sending a paging message for the terminal device to the network device, the paging message including the information indicating the PTW length. The core network device can configure the determined PTW length of the terminal device to the terminal device. For example, the core network device can send the PTW length of the terminal device to the terminal device using a transparent transmission method, so that the terminal device can determine whether it needs to listen for a wake-up signal or whether it needs to listen for a paging signal within the PTW length. The core network device can also send the paging message for the terminal device to the network device, the paging message including the information indicating the PTW length. Thus, the network device can determine whether it needs to send a wake-up signal or whether it needs to send a paging signal within the PTW length.

[0024] Thirdly, an information processing method according to an embodiment of this application includes: a network device determining a usage threshold for a wake-up signal; and the network device sending the usage threshold of the wake-up signal to a terminal device.

[0025] The wake-up signal usage threshold refers to the threshold value for whether a wake-up signal is valid. This threshold can be configured based on the network resources available to the network device. If network resources are abundant, the threshold value can be larger; if network resources are scarce, the threshold value can be smaller. Alternatively, it can be configured based on the eDRX period distribution of terminal devices in the network. If b% of the terminal eDRX periods are less than c, the threshold can be set to c. The values ​​of b and c can be determined based on the scenario. Both the network device and the terminal device can determine whether to use the wake-up signal based on this threshold. If the network device decides to use the wake-up signal, it will send the signal to the terminal device. If the terminal device decides to use the wake-up signal, it will listen for the signal.

[0026] As illustrated by the foregoing embodiments, in this application embodiment, the network device sends a usage threshold for the wake-up signal to the terminal device. Therefore, this application embodiment can realize the transmission of the wake-up signal usage threshold. After receiving the wake-up signal usage threshold, the terminal device can determine whether to listen for the wake-up signal based on the usage threshold and the eDRX period. When the eDRX period of the terminal device is less than or equal to the wake-up signal usage threshold, the terminal device listens for the wake-up signal, thereby saving paging power consumption and improving the utilization rate of network resources.

[0027] In one possible design of the third aspect, the method further includes: a network device receiving a paging message from a core network device, the paging message including an extended discontinuous reception eDRX period; when the network device determines that the eDRX period is less than or equal to a wake-up signal usage threshold, the network device sends a wake-up signal to the terminal device. Specifically, the core network device can send the determined eDRX period of the terminal device to the network device, which can receive the eDRX period. The network device can then compare the eDRX period with the wake-up signal usage threshold to determine their relative values ​​and whether to use the wake-up signal. When the eDRX period is determined to be less than or equal to the wake-up signal usage threshold, the network device sends a wake-up signal to the terminal device. The network device can wake up the terminal device using this wake-up signal. The network device can then page the terminal device again. If the terminal device does not hear the wake-up signal, it will not listen for paging messages from the network device until it does, thus saving network resources.

[0028] In one possible design of the third aspect, the usage threshold for the network device to send a wake-up signal to the terminal device includes: the network device sending the wake-up signal usage threshold via broadcast. Specifically, the network device can send a broadcast message to the terminal device, carrying the wake-up signal usage threshold in the broadcast message. After receiving the broadcast message, all terminal devices within the network device's cell can determine the wake-up signal usage threshold through the broadcast message. Sending the wake-up signal usage threshold via broadcast by the network device effectively improves information transmission efficiency.

[0029] In one possible design of the third aspect, the method further includes: the network device receiving a paging message from a terminal device via a core network device. The paging message includes information indicating the length of the Paging Time Window (PTW) of the terminal device, where the PTW length is greater than the time interval between two adjacent wake-up signals. The core network device can configure the determined PTW length of the terminal device to the terminal device. For example, the core network device can send the PTW length of the terminal device to the terminal device via transparent transmission, allowing the terminal device to determine whether it needs to listen for wake-up signals or paging signals within the PTW length.

[0030] Fourthly, embodiments of this application provide an information processing method, including: a terminal device receiving a usage threshold for a wake-up signal from a network device; when the extended discontinuous reception eDRX period of the terminal device is less than or equal to the usage threshold of the wake-up signal, the terminal device listens for the wake-up signal.

[0031] As illustrated by the foregoing embodiments, in this application embodiment, the terminal device receives a usage threshold for the wake-up signal from the network device. When the eDRX period of the terminal device is less than or equal to the usage threshold of the wake-up signal, the terminal device listens for the wake-up signal. Therefore, this application embodiment can realize the transmission of the wake-up signal usage threshold. After receiving the wake-up signal usage threshold, the terminal device can determine whether to listen for paging messages based on the usage threshold and the eDRX period. When the eDRX period of the terminal device is less than or equal to the usage threshold of the wake-up signal, the terminal device listens for the wake-up signal, thereby saving paging power consumption and improving the utilization rate of network resources.

[0032] In one possible design of the fourth aspect, the method further includes: when the eDRX period of the terminal device is greater than or equal to the threshold for using the wake-up signal, the terminal device listens for paging messages from the network device. Specifically, if the eDRX period of the terminal device is greater than the threshold, it directly listens for paging messages. Directly listening for paging messages means that the terminal device no longer listens for the wake-up signal, but instead listens for paging messages according to the PTW length and eDRX period.

[0033] In one possible design of the fourth aspect, the method further includes: when the terminal device detects a wake-up signal, it listens for paging messages from the network device within the duration indicated by the wake-up signal. Specifically, when it is determined that the eDRX period is less than or equal to the usage threshold of the wake-up signal, the network device sends a wake-up signal to the terminal device. The network device can wake up the terminal device through this wake-up signal, and then the network device can page the terminal device again. Therefore, if the terminal device does not detect a wake-up signal, it does not listen for paging messages from the network device until it detects the wake-up signal, thereby saving network resources.

[0034] In one possible design of the fourth aspect, the method further includes: the terminal device receiving information from the core network device indicating the length of the paging time window (PTW), wherein the length of the PTW is greater than the time interval between two adjacent wake-up signals. The core network device can configure the determined PTW length of the terminal device to the terminal device; for example, the core network device can send the PTW length of the terminal device to the terminal device via transparent transmission, so that the terminal device can determine whether it needs to listen for wake-up signals or paging signals within the PTW length.

[0035] Fifthly, embodiments of this application also provide a network device, including: a processing module, configured to determine configuration information of a wake-up signal, wherein the wake-up signal is used to indicate whether to page a terminal device within a certain period of time, and the configuration information is used to indicate the time interval between two adjacent wake-up signals (including the time interval between possible locations of the two wake-up signals); and a sending module, configured to send the configuration information of the wake-up signal to a core network device.

[0036] In the fifth aspect of this application, the constituent modules of the network device may also perform the steps described in the first aspect and various possible implementations, as detailed in the foregoing description of the first aspect and various possible implementations.

[0037] Sixthly, embodiments of this application also provide a core network device, including: a receiving module, configured to receive configuration information of a wake-up signal from a network device, wherein the wake-up signal is used by the network device to indicate whether to page a terminal device within a certain period of time, and the configuration information is used to indicate the time interval between two adjacent wake-up signals (including the time interval between possible locations of the two wake-up signals).

[0038] In the sixth aspect of this application, the constituent modules of the core network equipment may also perform the steps described in the second aspect and various possible implementations, as detailed in the foregoing description of the second aspect and various possible implementations.

[0039] In a seventh aspect, embodiments of this application also provide a core network device, including: the processing module, further configured to determine a usage threshold for the wake-up signal; and the sending module, further configured to send the usage threshold for the wake-up signal to the terminal device.

[0040] In the seventh aspect of this application, the constituent modules of the core network equipment may also perform the steps described in the third aspect and various possible implementations, as detailed in the foregoing description of the third aspect and various possible implementations.

[0041] Eighthly, embodiments of this application provide a terminal device, including: a receiving module for receiving a usage threshold of a wake-up signal from a network device; and a processing module for monitoring the wake-up signal when the extended discontinuous reception eDRX period of the terminal device is less than or equal to the usage threshold of the wake-up signal.

[0042] In the eighth aspect of this application, the constituent modules of the terminal device may also perform the steps described in the fourth aspect and various possible implementations, as detailed in the foregoing description of the fourth aspect and various possible implementations.

[0043] Ninthly, embodiments of this application provide an information processing method, comprising: a network device determining a data early transmission terminal type supported by the network device, the data early transmission terminal type including at least one of a terminal device using user plane UP optimization mode for data early transmission or a terminal device using control plane CP optimization mode for data early transmission; the network device sending information about the data early transmission terminal type supported by the network device to the terminal device.

[0044] Early data transmission refers to transmitting data before establishing a connection, as opposed to traditional connection establishment and transmission. It's a faster transmission method. Early data transmission can also refer to transmitting data during random access. Traditional data transmission involves entering a connected state via random access, transmitting data within that state, and finally releasing the connection. However, in this embodiment, the early data transmission process allows the terminal to transmit uplink data during random access. If the data is small, entering a connected state is not necessary, and the data transmission process ends together with the random access process.

[0045] In this embodiment, the network device sends information about the data early transmission terminal types supported by the network device to the terminal device, enabling the terminal device to determine the data early transmission terminal type supported by the network device based on the information sent by the network device. In this embodiment, different types of terminal devices can also be individually instructed whether they support the data early transmission process. This embodiment enables the network device to individually support at least one data early transmission terminal type for data early transmission.

[0046] In one possible design of the ninth aspect, the network device determines the data early transmission terminal type supported by the network device, including: the network device determining that it supports terminal devices using UP optimization mode for data early transmission. The network device may support terminal devices using UP optimization mode for data early transmission, and the type of data early transmission terminal supported by the network device can be determined by the network device's configuration parameters.

[0047] In one possible design of the ninth aspect, the network device sends information about the data early transmission terminal type supported by the network device to the terminal device, including: the network device sending information indicating random access resources for data early transmission to the terminal device, the information indicating random access resources for data early transmission being used to instruct the network device to support the terminal device to perform data early transmission using the UP optimization mode; or, the network device sending information indicating random access resources for data early transmission and information instructing the network device to support the terminal device to perform data early transmission using the UP optimization mode.

[0048] The information indicating the random access resources used for early data transmission refers to the resource configuration information of the random access resources dedicated to early data transmission broadcast by the network device. By indicating the random access resources used for early data transmission, the network device can be instructed to support terminal devices using the UP optimization mode for early data transmission. Thus, by parsing the information indicating the random access resources used for early data transmission, the terminal device can determine that the network device supports terminal devices using the UP optimization mode for early data transmission.

[0049] For example, the information indicating that the network device supports terminal devices using the UP optimization mode for early data transmission can be a specific indication message. This indication message can be independent of the information indicating the random access resources used for early data transmission. The network device sends the information indicating that the network device supports terminal devices using the UP optimization mode for early data transmission to the terminal device. Thus, by parsing the information indicating that the network device supports terminal devices using the UP optimization mode for early data transmission, the terminal device can determine that the network device supports terminal devices using the UP optimization mode for early data transmission.

[0050] In one possible design of the ninth aspect, the network device sends information about the data early transmission terminal type supported by the network device to the terminal device, including: the network device sending information to the terminal device indicating that the network device supports terminal devices using UP optimization mode; the network device sending information to the terminal device indicating random access resources for data early transmission; wherein, the information indicating that the network device supports terminal devices using UP optimization mode and the information indicating random access resources for data early transmission are used to instruct the network device to support terminal devices using UP optimization mode for data early transmission. In the foregoing embodiments of this application, the network device supporting terminal devices using UP optimization mode means that the network device supports terminal devices using UP optimization mode. That is, the information sent by the network device indicating that the network device supports terminal devices using UP optimization mode only indicates that the network device supports terminal devices using UP optimization mode. If the network device also sends information indicating random access resources for data early transmission... If the terminal device receives information indicating that the network device supports terminal devices using UP optimization mode, and also receives information indicating random access resources for early data transmission, the terminal device can determine that the network device supports terminal devices using UP optimization mode for early data transmission based on these two pieces of information.

[0051] In one possible design of the ninth aspect, the network device determines the data early transmission terminal type supported by the network device, including: the network device determining that it supports terminal devices using CP optimization mode for data early transmission. Wherein, the network device can support terminal devices using CP optimization mode for data early transmission, and the type of data early transmission terminal supported by the network device can be determined by the network device's configuration parameters.

[0052] In one possible design of the ninth aspect, the network device sends information about the data early transmission terminal type supported by the network device to the terminal device, including: the network device sending information indicating random access resources for data early transmission to the terminal device, the information indicating random access resources for data early transmission being used to instruct the network device to support the terminal device to perform data early transmission using the CP optimization mode; or, the network device sending information indicating random access resources for data early transmission and information instructing the network device to support the terminal device to perform data early transmission using the CP optimization mode.

[0053] The information indicating the random access resources used for early data transmission refers to the resource configuration information of the random access resources dedicated to early data transmission broadcast by the network device. This information instructs the network device to support terminal devices using the CP optimization mode for early data transmission. By parsing this information, the terminal device can determine that the network device supports terminal devices using the CP optimization mode for early data transmission. Alternatively, the information indicating that the network device supports terminal devices using the CP optimization mode for early data transmission can be a separate instruction. This instruction can be independent of the information indicating the random access resources used for early data transmission. The network device sends this instruction to the terminal device, and by parsing it, the terminal device can determine that the network device supports terminal devices using the CP optimization mode for early data transmission.

[0054] In one possible design of the ninth aspect, the network device sends information about the data early transmission terminal type supported by the network device to the terminal device, including: the network device sending information to the terminal device indicating that the network device supports terminal devices using CP optimization mode; the network device sending information to the terminal device indicating random access resources for data early transmission; wherein, the information indicating that the network device supports terminal devices using CP optimization mode and the information indicating random access resources for data early transmission are used to instruct the network device to support terminal devices using CP optimization mode for data early transmission. In the foregoing embodiments of this application, the network device supporting terminal devices using CP optimization mode means that the network device supports terminal devices using CP optimization mode. That is, the information sent by the network device indicating that the network device supports terminal devices using CP optimization mode only indicates that the network device supports terminal devices using CP optimization mode. If the network device also sends information indicating random access resources for data early transmission... If the terminal device receives information indicating that the network device supports the use of CP optimization mode for terminal devices, and also receives information indicating random access resources for early data transmission, the terminal device can determine that the network device supports the use of CP optimization mode for early data transmission based on these two pieces of information.

[0055] In one possible design of the ninth aspect, the network device determines the data early transmission terminal types it supports, including: the network device determines that it simultaneously supports terminal devices using UP optimization mode and terminal devices using CP optimization mode for data early transmission. The network device can support both UP optimization mode and CP optimization mode terminal devices for data early transmission, and the type of data early transmission terminal supported by the network device can be determined by the network device's configuration parameters.

[0056] In one possible design of the ninth aspect, the network device sends information about the data early transmission terminal type supported by the network device to the terminal device, including: the network device sending information indicating random access resources for data early transmission to the terminal device, wherein the information indicating random access resources for data early transmission is used to indicate that the network device simultaneously supports data early transmission by terminal devices using UP optimization mode and terminal devices using CP optimization mode; or, the network device sending information indicating random access resources for data early transmission and information indicating that the network device simultaneously supports data early transmission by terminal devices using UP optimization mode and terminal devices using CP optimization mode to the terminal device.

[0057] The information indicating the random access resources used for early data transmission refers to the resource configuration information of the random access resources dedicated to early data transmission broadcast by the network device. By indicating the random access resources used for early data transmission, the network device can be instructed to simultaneously support terminal devices using UP optimization mode and terminal devices using CP optimization mode for early data transmission. Thus, by parsing the information indicating the random access resources used for early data transmission, the terminal device can determine that the network device simultaneously supports terminal devices using UP optimization mode and terminal devices using CP optimization mode for early data transmission. For example, the information indicating that a network device simultaneously supports early data transmission for terminal devices using both UP-optimized mode and CP-optimized mode can be a specific indication message. This indication message can be independent of the information indicating random access resources used for early data transmission. The network device sends this information to the terminal device, and the terminal device can then determine that the network device simultaneously supports early data transmission for both UP-optimized and CP-optimized modes by parsing the information.

[0058] In one possible design of the ninth aspect, the network device sends information about the data early transmission terminal type supported by the network device to the terminal device, including: the network device sending information to the terminal device indicating that the network device supports data early transmission using the CP optimization mode, and information instructing the network device to support data early transmission using the UP optimization mode. The network device may send two instruction messages, one indicating that the network device supports data early transmission using the CP optimization mode, and the other indicating that the network device supports data early transmission using the UP optimization mode.

[0059] In one possible design of the ninth aspect, the network device sends information about the data early transmission terminal type supported by the network device to the terminal device, including: the network device sending information indicating random access resources for data early transmission and information indicating that the network device supports data early transmission by the terminal device using the UP optimization mode, wherein the information indicating random access resources for data early transmission is used to indicate that the network device supports data early transmission by the terminal device using the CP optimization mode; or, the network device sending information indicating random access resources for data early transmission and information indicating that the network device supports data early transmission by the terminal device using the CP optimization mode, wherein the information indicating random access resources for data early transmission is used to indicate that the network device supports data early transmission by the terminal device using the UP optimization mode.

[0060] In one possible design of the ninth aspect, the network device sends information about the data early transmission terminal types supported by the network device to the terminal device, including: the network device sending information about the data early transmission terminal types supported by the network device within a specific range, wherein the specific range includes at least one of the following: the network device's cell, carrier, or coverage level. The specific range can be predefined by the protocol or indicated by the network device to the terminal device, which will not be elaborated here. If the network device determines the data early transmission terminal types supported within a specific range, the terminal device, when determining which data early transmission terminal type the network device supports, also needs to first determine whether it meets the requirements of that specific range. For example: determining the carrier used to initiate data early transmission, randomly selecting from the available carriers broadcast by the base station or selecting according to its own ID, for example, the carrier ID used is the terminal ID modulo the number of carriers available for data early transmission, where mod represents the remainder. If the base station indicates support for data early transmission on this carrier for the terminal's category, then the data early transmission procedure is used. For example, to determine the coverage level for initiating early data transmission, the terminal determines the coverage level based on its own measured link quality and the correspondence between the link quality and coverage level broadcast by the base station, such as several thresholds. If the base station indicates that it supports early data transmission of the terminal's category at this coverage level, then the early data transmission procedure is used.

[0101] This application provides an information processing method and apparatus that can transmit configuration information for wake-up signals, enabling terminal devices to save paging power consumption and improve network resource utilization by listening to wake-up signals.

[0102] Figure 1This diagram illustrates a possible structure of a radio access network (RAN) according to an embodiment of this application. The RAN can be a base station access system for a 2G network (i.e., the RAN includes base stations and base station controllers), a base station access system for a 3G network (i.e., the RAN includes base stations and RNCs), a base station access system for a 4G network (i.e., the RAN includes eNBs and RNCs), or a base station access system for a 5G network. The CN can be an MME and / or S-GW for a 4G network, an SGSN or GGSN for a 3G network, or a next-generation core network (NG-Core) for a 5G network.

[0103] The RAN includes one or more network devices 20. The radio access network can be connected to the core network (CN) device 30. The network device 20 can be any device with wireless transceiver capabilities, or a chip located within a device with specific wireless transceiver capabilities. The network device 20 includes, but is not limited to: base stations (e.g., base stations BS, NodeB, evolved NodeB or eNB, gNodeB or gNB in ​​5G communication systems, base stations in future communication systems, access nodes in WiFi systems, wireless relay nodes, wireless backhaul nodes, etc.). Base stations can be: macro base stations, micro base stations, pico base stations, small cells, relay stations, etc. Multiple base stations can support networks using one or more of the technologies mentioned above, or future evolved networks. The core network can support networks using one or more of the technologies mentioned above, or future evolved networks. A base station can contain one or more co-located or non-co-located transmission receiving points (TRPs). Network device 20 can also be a radio controller, centralized unit (CU), or distributed unit (DU) in a cloud radio access network (CRAN) scenario.

The base station can communicate with terminal device 10, or it can communicate with terminal device 10 through a relay station. Terminal 10 can support communication with multiple base stations using different technologies. For example, the terminal device can support communication with base stations supporting LTE networks, base stations supporting 5G networks, and dual connections with both LTE and 5G base stations. For example, connecting the terminal to a radio access network (RAN) node in a wireless network.Currently, some examples of RAN nodes include: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wi-Fi) access point (AP), etc. In a network architecture, network equipment may include centralized unit (CU) nodes, distributed unit (DU) nodes, or RAN equipment including both CU and DU nodes.

[0105] The core network equipment 30 can be a Mobility Management Entity (MME) in a 4G network or an Access Management Function (AMF) in a 5G network. The core network equipment 30 can be a physical entity, a functional entity, or a chip located within a physical entity.

[0106] First, the paging process in the embodiments of this application will be illustrated, taking paging in an NB-IoT scenario as an example, such as... Figure 2 The diagram shown is a schematic of the paging terminal device in the core network equipment of this application embodiment. The paging process requires the following configuration:

[0107] The core network equipment configures the paging time window (PTW) length and the extended discontinuous reception (eDRX) period (TeDRX) for the terminal equipment.

[0108] The base station broadcasts the paging configuration of its cell via system broadcast, including the Discontinuous Reception (DRX) DRX period (TDRX) and the number of paging opportunities (POs) within a DRX period, allowing the terminal device to calculate its PO location within the current cell based on its ID. One eDRX contains one PTW, and one PTW contains several DRXs. When this application is used in other scenarios, the aforementioned time window, DRX period, or eDRX period can be replaced with other terms, as long as the functionality is the same or similar.

[0109] The behavior of each network element during the paging process will be explained in detail below:

[0110] Core network equipment (e.g., MME): When a core network device pages a terminal device, it sends a paging message containing the terminal device's identifier ID, PTW, and eDRX period to the base station, which then pages the terminal device. After initiating paging, the core network device starts a timer T3413. If the timer expires without receiving a paging response from the terminal device, it retransmits the paging message and restarts the timer. If a paging response is received, the timer stops.

[0111] Base station (e.g., eNB): After receiving the paging message from the core network equipment, the base station will page the terminal equipment on the corresponding PO in each DRX cycle within the PTW of the terminal equipment according to the terminal equipment ID, PTW length, eDRX cycle and its own paging configuration information carried in the core network paging message.

[0112] Terminal equipment (e.g., UE): Based on the core network equipment configuration, the terminal equipment wakes up once every TeDRX interval and listens for paging messages within the PTW length. Specifically, within the PTW, the terminal equipment calculates a unique PO location within each DRX cycle based on its own ID, according to the paging configuration information broadcast by the base station of its cell, and listens for paging messages on the corresponding PO. For example, the terminal equipment can first listen to the Physical Downlink Control Channel (PDCCH), and then listen to paging messages on the Physical Downlink Shared Channel (PDSCH) according to the scheduling information in the PDCCH to see if it contains its own ID. If it does, it means it has been paging by the network.

[0113] In the paging process described above, an important principle is that within a single PTW (Paging Terminal Ward), the core network must have multiple opportunities to attempt paging of the terminal device. Otherwise, if the core network paging terminal fails once, it can only attempt paging in the next eDRX cycle, resulting in excessive latency; for example, the maximum eDRX cycle is 2.91 hours.

[0114] To optimize the paging process described above, in this embodiment, the terminal device listens for paging by attempting to decode the PDCCH scrambled with the Paging-Radio Network Temporary Identity (P-RNTI) at the corresponding PO location according to the DRX cycle. If decoding is successful, it continues to decode the paging message on the PDSCH according to the PDCCH schedule to further determine whether the paging message contains its own ID. This operation incurs significant power consumption when listening to the PDCCH, especially when the terminal device's paging cycle is short and it frequently listens to the PDCCH for paging. In this embodiment, a wake-up signal is used for the paging process. The wake-up signal precedes the PDCCH in the PO, indicating whether the terminal device will be paging in subsequent POs. If so, the terminal device listens to the PDCCH at the corresponding location; otherwise, it does not. Since the wake-up signal design is relatively simple, its power consumption is lower compared to listening to the PDCCH. Therefore, if the terminal device is not paging, it only needs to listen to the wake-up signal once, without listening to the PDCCH, thus reducing power consumption. It indicates whether the terminal device will receive a page from the PO in the future. If there is a page, the terminal will listen to the PDCCH at the corresponding PO location; otherwise, it will not.

[0115] For example, a single wake-up signal is used to indicate whether a terminal device is paging in a future point of sale (PO). If a single wake-up signal can indicate whether a terminal device is paging in multiple future POs, then for the terminal, it can listen to fewer PDCCHs, which is beneficial for power consumption; for the base station, it can send fewer wake-up signals in subsequent POs, which is beneficial for network resource utilization.

[0116] However, to achieve this, it is necessary to ensure that there are multiple wake-up signals within a PTW to avoid paging delays caused by having to wait for the next eDRX cycle due to missing a wake-up opportunity. The PTW length is configured by the MME, but the position and period of the wake-up signal are configured by the base station. The two cannot be guaranteed to be configured in coordination, and it is impossible to guarantee that there are multiple wake-up signals within a PTW.

[0117] In addition, the gain of the wake-up signal mainly applies to terminal devices with very short paging cycles but low probability of being paged. Terminals with longer paging cycles and higher paging probabilities are more likely to need to listen to both the wake-up signal and the traditional PDCCH, and may even experience negative gain.

[0118] Please see Figure 3 The diagram shown illustrates an interaction process between network devices, terminal devices, and core network devices according to an embodiment of this application. The information processing method provided in this embodiment mainly includes the following processes:

[0119] S01. The network device broadcasts the cell's DRX cycle, wake-up signal configuration information, and wake-up signal usage threshold. In this embodiment, step S01 is merely an example of one execution step by the network device, and is not limited to this. The network device may also broadcast at least one of the cell's DRX cycle, wake-up signal configuration information, and wake-up signal usage threshold. The cell's DRX cycle can be configured by the base station, and each terminal device has one paging opportunity within one DRX cycle. The wake-up signal indicates whether to page the terminal device within a certain duration, the value of which can be determined by the network device.

[0120] In this application, the configuration information of the wake-up signal is used to indicate the time interval between two adjacent wake-up signals, or the configuration information of the wake-up signal is used to indicate the time interval between two consecutive wake-up signal detections by the terminal device. For example: the wake-up signal can have two states. State 1: The network device sends a wake-up signal indicating that it needs to wake up the terminal device; if the network device does not send a wake-up signal, it indicates that the terminal device will not be woken up. State 2: The wake-up signal has two or more states; state 1 (e.g., 01) indicates that the terminal device is woken up, and state 2 (e.g., 10) indicates that the terminal device is not woken up.

[0121] For example, a wake-up signal indicates whether a terminal device will be paging you within a certain period of time. Any signal that can serve a wake-up function can be considered a wake-up signal. For instance, the presence or absence of a signal can indicate whether paging will occur within a future period. If a terminal device at a specific location detects a wake-up signal, it means the network device will send a paging message. If no wake-up signal is detected, it means there will be no further paging messages until the terminal device tries to detect the wake-up signal again at the next signal location. Alternatively, different states of the wake-up signal can indicate whether there will be further paging messages within a future period. If a terminal device detects a specific signal state at a specific location, such as 01, it means a paging message is imminent. If another state is detected, such as 10, it means there will be no further paging messages. In this embodiment, the wake-up signal can reduce the listening overhead of a terminal device monitoring traditional paging. Because the wake-up signal is relatively simple, monitoring it saves resources compared to monitoring the PDCCH in traditional paging. If the terminal device is not being paged, it only listens for this wake-up signal, thereby saving network resources.

[0122] In this application, the time interval between two adjacent wake-up signals includes at least one of the following: the time interval between two adjacent wake-up signals, or the time interval between possible locations of two wake-up signals.

[0123] The configuration information for the wake-up signal is used to indicate the time interval between two adjacent wake-up signals. There are various ways to implement this configuration information, which will be illustrated with examples below. For instance, the configuration information for the wake-up signal includes at least one of the following: information indicating the period of the wake-up signal, information indicating the correspondence between the wake-up signal and the DRX period, or information indicating the duration. Specifically, the information indicating the period of the wake-up signal can be the period information of the wake-up signal itself, or other information that can determine the period value of the wake-up signal. The information indicating the correspondence between the wake-up signal and the DRX period can specifically be the correspondence information between the wake-up signal and the DRX period. For example, the correspondence between the wake-up signal and the DRX period can be: how many DRX periods correspond to one wake-up signal. For example, the letter 'x' represents the number of DRX periods corresponding to one wake-up signal, and the value of 'x' can be a positive integer such as 1 or 2. The information indicating the duration is the value indicating whether the wake-up signal needs to page the terminal device within a certain duration. For example, if the duration represents 3 subframes, then the wake-up signal needs to page the terminal device within 3 subframes. In this embodiment, the usage threshold of the wake-up signal refers to the eDRX period threshold for using the wake-up signal. The unit of this usage threshold can be a time unit such as seconds or milliseconds, or it can be a subframe, system frame, or superframe that reflects time. The usage threshold of the wake-up signal is a threshold value for whether the wake-up signal is valid. This usage threshold can be configured according to the network resource situation of the network device. If there are more network resources, the usage threshold can be configured to be larger; if there are fewer network resources, the usage threshold can be configured to be smaller. For example, it can also be configured according to the eDRX period distribution of terminal devices in the network. If b% of the terminal eDRX periods are less than c, the usage threshold can be configured to be c. The values ​​of b and c can be determined according to the scenario. The network device and the terminal device can determine whether to use the wake-up signal based on the usage threshold of the wake-up signal. If the network device determines to use the wake-up signal, it will send the wake-up signal to the terminal device. If the terminal device determines to use the wake-up signal, it will listen for the wake-up signal.

[0124] In some embodiments of this application, the configuration information of the wake-up signal further includes: information indicating the start position and duration of the wake-up signal within a cycle.

[0125] The start position and duration of the wake-up signal within a cycle can serve as configuration information for the wake-up signal. The start position indicates the position at which the wake-up signal begins to be sent within a cycle, while the duration indicates the number of time units occupied by the wake-up signal within a cycle. By indicating the start position and duration of the wake-up signal within a cycle, the signal configuration parameters of the wake-up signal can be described more accurately.

[0126] S02. The network device sends configuration information for a wake-up signal to the core network device. Furthermore, the network device can also send a DRX cycle.

[0127] In this embodiment, step S02 is merely an example of one execution step of the network device, and is not limited to this. The network device may also send at least one of the following: configuration information for a DRX period and a wake-up signal. Specifically, the network device sends a DRX period to the core network device, which can obtain the value parameters of the DRX period. The network device sends configuration information for the wake-up signal to the core network device, which can obtain the configuration information of the wake-up signal, thereby allowing the core network device to determine the signal configuration parameters of the wake-up signal.

[0128] In some embodiments of this application, the configuration information for the network device to send a wake-up signal to the core network device includes:

[0129] The network device sends an interface establishment request message to the core network device. This message carries configuration information for the wake-up signal; or...

[0130] The network device sends a configuration update message to the core network device, and the configuration update message carries the configuration information of the wake-up signal.

[0131] The interface establishment request message refers to the request message sent by the network device when establishing an interface between the network device and the core network device. This message carries the configuration information for the wake-up signal. For example, a new field can be added to the interface establishment request message to carry the wake-up signal configuration information, or an expandable field in the interface establishment request message can be used. The network device configuration update message indicates a notification message sent by the network device to the core network device when there is a configuration update. For example, a new field can be added to the configuration update message to carry the wake-up signal configuration information, or an expandable field in the configuration update message can be used. An example is provided in subsequent step S03.

[0132] S03. Core network equipment establishes a message through the S1 interface or receives configuration information for the wake-up signal through a base station configuration update message. Furthermore, it receives the DRX cycle through the S1 interface or through a base station configuration update message.

[0133] For example, a base station can send wake-up signal configuration information to the core network equipment in multiple processes or messages. For instance, it can send it to the core network equipment in the corresponding interface establishment message (e.g., the S1 interface establishment request message) or in the base station configuration update message during the base station configuration update process after the interface establishment is completed.

[0134] S04. The core network equipment determines the PTW length of the terminal equipment based on the configuration information of the wake-up signal.

[0135] In this embodiment, step S04 is merely an example of one execution step of the core device, and is not limited to this. The network device can also determine the PTW length of the terminal device based on the configuration information of the DRX cycle and the wake-up signal. For example, the core network device can determine the PTW length of the terminal device based on the configuration information of the wake-up signal. The PTW length determined by the core network device is greater than the time interval between two adjacent wake-up signals, that is, there is more than one wake-up signal within one PTW, thereby avoiding the paging delay caused by having to wait for the next eDRX cycle due to missing a wake-up opportunity, and improving the utilization rate of network resources.

[0136] In some embodiments of this application, the configuration information of the wake-up signal includes information indicating the period of the wake-up signal. The core network device determines the PTW length of the terminal device based on the configuration information of the wake-up signal, including:

[0137] The core network equipment determines the PTW length based on the period of the wake-up signal, and the PTW length is greater than the period of the wake-up signal.

[0138] The core network equipment determines the PTW length based on the period of the wake-up signal. The PTW length determined by the core network is greater than the period of the wake-up signal. For example, the PTW length can be greater than or equal to 'a' times the period of the wake-up signal. Thus, there can be more than 'a' wake-up signals within one PTW length. The value of 'a' can be a positive integer. For instance, if 'a' is 2, the core network equipment calculates that there are 2 wake-up signals within the PTW length. Similarly, if 'a' is 3, the core network equipment calculates that there are 3 wake-up signals within the PTW length.

[0139] In some embodiments of this application, the configuration information of the wake-up signal includes information indicating the correspondence between the wake-up signal and the discontinuous reception DRX period. The core network device determines the PTW length of the terminal device based on the configuration information of the wake-up signal, including:

[0140] The core network equipment determines the correspondence between the wake-up signal and the discontinuous reception DRX cycle as follows: one wake-up signal corresponds to x DRX cycles, where x is a positive integer;

[0141] The core network equipment determines the PTW length based on the correspondence between the wake-up signal and the discontinuous reception DRX period. The PTW length is greater than the result obtained by multiplying x by the value of the DRX period.

[0142] The core network equipment determines the PTW length based on the correspondence between wake-up signals and discontinuous reception DRX cycles. One wake-up signal corresponds to x DRX cycles, where x is a positive integer, for example, x = 2. The PTW length determined by the core network is greater than x multiplied by the value of the DRX cycle. For example, the PTW length can be greater than or equal to a multiplied by x, then multiplied by the value of the DRX cycle. Since x multiplied by the DRX cycle corresponds to one wake-up signal, there can be more than a wake-up signals within one PTW length. The value of a can be a positive integer; for example, when a is 2, the core network equipment calculates that there are 2 wake-up signals within the PTW length. Similarly, when a is 3, the core network equipment calculates that there are 3 wake-up signals within the PTW length.

[0143] In some embodiments of this application, the configuration information of the wake-up signal includes information indicating the duration. The core network device determines the paging time window (PTW) length of the terminal device based on the configuration information of the wake-up signal, including:

[0144] The core network equipment determines the PTW length based on the duration information, and the PTW length is greater than the duration value.

[0145] The core network equipment determines the PTW length based on the duration of the wake-up signal. The PTW length determined by the core network is greater than the wake-up signal duration. For example, the PTW length can be greater than or equal to 'a' times the wake-up signal duration. Thus, there can be more than 'a' wake-up signals within a PTW length. The value of 'a' can be a positive integer. For instance, if 'a' is 2, the core network equipment calculates that there are 2 wake-up signals within the PTW length. Similarly, if 'a' is 3, the core network equipment calculates that there are 3 wake-up signals within the PTW length.

[0146] S05. Configure the PTW length of the terminal equipment in the core network equipment.

[0147] In this embodiment, step S05 is merely an example of one execution step of the core device, and is not limited to this. The network device can also configure the PTW length and eDRX period of the terminal device. Specifically, the core network device can configure the determined PTW length and eDRX period of the terminal device to the terminal device, for example, by sending the PTW length and eDRX period of the terminal device to the terminal device via transparent transmission.

[0148] S06. The terminal device can listen for paging messages or wake-up signals based on the configuration information of the eDRX period, PTW length, and wake-up signal. If the terminal device's eDRX period is less than or equal to the usage threshold, it will first listen for the wake-up signal, and then listen for the paging message upon receiving the wake-up signal; if the terminal device's eDRX period is greater than the usage threshold, it will directly listen for the paging message.

[0149] In this process, the terminal device obtains the wake-up signal usage threshold in step S01, and then obtains the PTW length and eDRX period in step S05. Next, the terminal device determines whether its eDRX period is less than or equal to the usage threshold. If the eDRX period is less than or equal to the threshold, it first listens for the wake-up signal, and then listens for the paging message upon receiving the wake-up signal. If the eDRX period is greater than the threshold, it directly listens for the paging message. Directly listening for the paging message means that the terminal device no longer listens for the wake-up signal, but instead listens for the paging message according to the PTW length and eDRX period.

[0150] It should be noted that in some embodiments of this application, the terminal device can also determine whether its eDRX cycle is less than a usage threshold. If the eDRX cycle is less than the usage threshold, it first listens for a wake-up signal, and then listens for a paging message upon receiving the wake-up signal. If the eDRX cycle is greater than or equal to the usage threshold, it directly listens for the paging message. The terminal device's behavior when the eDRX cycle is equal to the usage threshold can be determined according to the application scenario; this is merely an example.

[0151] S07. The core network device sends a paging message to the network device, including the PTW length of the terminal device. Furthermore, the paging message may also include the terminal device's ID and / or the eDRX period.

[0152] In this embodiment of the application, when the core network device needs to page the terminal device, the core network device can send a paging message to the network device.

[0153] S08. The network device determines whether to use a wake-up signal based on the eDRX cycle of the terminal device. If the wake-up signal is used, proceed to step S09, and then proceed to step S10. If the wake-up signal is not used, no wake-up signal is sent, and only step S11 is executed.

[0154] S09. The network device sends a wake-up signal to the terminal device based on the PTW length, eDRX period, wake-up signal configuration information, and the terminal device ID.

[0155] S10. The network device sends a paging message to the terminal device based on the PTW length, eDRX period, and the terminal device ID.

[0156] S11. The network device sends a paging message to the terminal device based on the PTW length, eDRX period, and the terminal device ID.

[0157] After receiving a paging message from the core network device, the network device can determine whether the terminal device's eDRX period is less than or equal to the usage threshold. If the terminal device's eDRX period is less than or equal to the usage threshold, the network device can first send a wake-up signal and then send the paging message. If the terminal device's eDRX period is greater than the threshold, the paging message is sent directly. Sending the paging message directly means that the network device no longer sends a listening signal, but instead sends the paging message according to the PTW length and eDRX period.

[0158] As illustrated by the foregoing embodiments, in this application embodiment, the network device can determine the configuration information of the wake-up signal. The wake-up signal indicates whether to page the terminal device within a certain period of time, and the configuration information indicates the time interval between two adjacent wake-up signals. The network device sends the configuration information of the wake-up signal to the core network device. The core network device can receive the configuration information of the wake-up signal from the network device. Therefore, this application embodiment can realize the transmission of the configuration information of the wake-up signal. After receiving the configuration information of the wake-up signal, the core network device can complete the paging configuration of the terminal device based on the configuration parameters, so that the terminal device can save paging power consumption by listening to the wake-up signal and improve the utilization rate of network resources.

[0159] The information processing method provided in this application embodiment will be described from the perspectives of network devices, core network devices, and terminal devices respectively. First, please refer to... Figure 4 As shown in the figure, this application provides an information processing method, including:

[0160] S401. The network device determines the configuration information of the wake-up signal. The wake-up signal is used to indicate whether to page the terminal device within a certain period of time. The configuration information is used to indicate the time interval between two adjacent wake-up signals.

[0161] In this embodiment, the network device can configure the wake-up signal, and after configuring the wake-up signal, the network device can generate configuration information for the wake-up signal. Alternatively, the network device can obtain the configuration information for the wake-up signal by reading its default configuration parameters.

[0162] The configuration information of the wake-up signal in this embodiment is used to indicate the time interval between two adjacent wake-up signals. The configuration information can be implemented in various ways, as illustrated below. For example, the configuration information of the wake-up signal includes at least one of the following: information indicating the period of the wake-up signal, information indicating the correspondence between the wake-up signal and the DRX period, or information indicating the duration. Specifically, the information indicating the period of the wake-up signal can be the period information of the wake-up signal, or other information that can determine the period value of the wake-up signal. The information indicating the correspondence between the wake-up signal and the DRX period can specifically be the correspondence information between the wake-up signal and the DRX period. For example, the correspondence between the wake-up signal and the DRX period can be: how many DRX periods correspond to one wake-up signal. For example, the letter x represents the number of DRX periods corresponding to one wake-up signal, and the value of x can be a positive integer such as 1 or 2. The information indicating the duration is the value indicating whether the wake-up signal needs to page the terminal device within a certain duration. For example, if the duration represents 3 subframes, then the wake-up signal needs to page the terminal device within 3 subframes. In the embodiments of this application, the usage threshold of the wake-up signal refers to the eDRX period threshold for using the wake-up signal. The value of the usage threshold can be a time unit such as seconds or milliseconds, or it can be a subframe, system frame, superframe, etc. that can reflect time.

[0163] In some embodiments of this application, the configuration information of the wake-up signal further includes: information indicating the start position and duration of the wake-up signal within a cycle.

[0164] The start position and duration of the wake-up signal within a cycle can serve as configuration information for the wake-up signal. The start position indicates the position at which the wake-up signal begins to be sent within a cycle, while the duration indicates the number of time units occupied by the wake-up signal within a cycle. By indicating the start position and duration of the wake-up signal within a cycle, the signal configuration parameters of the wake-up signal can be described more accurately.

[0165] S402. Configuration information for network devices to send wake-up signals to core network devices.

[0166] In some embodiments of this application, after the network device obtains the configuration information of the wake-up signal, the network device sends the configuration information of the wake-up signal to the core network device. For example, the network device can send the configuration information of the wake-up signal through the interface between the network device and the core network device, such as using the S1 interface to send the configuration information of the wake-up signal.

[0167] In some embodiments of this application, the information processing method provided in this application may further include the following steps:

[0168] Network devices send information indicating DRX cycles to core network devices.

[0169] The DRX period can be configured by the base station, and each terminal device has one paging opportunity within a DRX period. The information indicating the DRX period can be specific to the DRX period configuration information or other information that can determine the DRX period value. The network device sends the DRX period indication information to the core network device, enabling the core network device to obtain this information and thus determine the DRX period value parameters based on it.

[0170] In some embodiments of this application, the configuration information for the network device to send a wake-up signal to the core network device includes:

[0171] The network device sends an interface establishment request message to the core network device. This message carries configuration information for the wake-up signal; or...

[0172] The network device sends a configuration update message to the core network device, and the configuration update message carries the configuration information of the wake-up signal.

[0173] The interface establishment request message is a request message sent by a network device when establishing an interface between a network device and a core network device. This message carries the configuration information for the wake-up signal. For example, a new field can be added to the interface establishment request message to carry the wake-up signal configuration information, or an expandable field within the interface establishment request message can be used. The network device configuration update message indicates a notification message sent by the network device to the core network device when there is a configuration update. For example, a new field can be added to the configuration update message to carry the wake-up signal configuration information, or an expandable field within the configuration update message can be used.

[0174] As illustrated by the foregoing embodiments, in this application embodiment, the network device can determine the configuration information of the wake-up signal. The wake-up signal indicates whether to page the terminal device within a certain period of time, and the configuration information indicates the time interval between two adjacent wake-up signals. The network device sends the configuration information of the wake-up signal to the core network device. The core network device can receive the configuration information of the wake-up signal from the network device. Therefore, this application embodiment can realize the transmission of the configuration information of the wake-up signal. After receiving the configuration information of the wake-up signal, the core network device can complete the paging configuration of the terminal device based on the configuration parameters, so that the terminal device can save paging power consumption by listening to the wake-up signal and improve the utilization rate of network resources.

[0175] The foregoing embodiments described the information processing method provided in this application from the perspective of network devices. The following description describes the information processing method provided in this application from the perspective of core network devices. Please refer to [link to relevant documentation]. Figure 5 As shown in the figure, this application provides an information processing method, including:

[0176] S501. The core network device receives configuration information from the wake-up signal from the network device. The wake-up signal is used by the network device to indicate whether to page the terminal device within a certain period of time. The configuration information is used to indicate the time interval between two adjacent wake-up signals.

[0177] In this embodiment of the application, the core network device receives configuration information of the wake-up signal from the network device. For example, the core network device can receive the configuration information of the wake-up signal through the interface between the network device and the core network device, such as using the S1 interface to receive the configuration information of the wake-up signal.

[0178] The configuration information of the wake-up signal in this embodiment is used to indicate the time interval between two adjacent wake-up signals. The configuration information can be implemented in various ways, as illustrated below. For example, the configuration information of the wake-up signal includes at least one of the following: information indicating the period of the wake-up signal, information indicating the correspondence between the wake-up signal and the DRX period, or information indicating the duration. Specifically, the information indicating the period of the wake-up signal can be the period information of the wake-up signal, or other information that can determine the period value of the wake-up signal. The information indicating the correspondence between the wake-up signal and the DRX period can specifically be the correspondence information between the wake-up signal and the DRX period. For example, the correspondence between the wake-up signal and the DRX period can be: how many DRX periods correspond to one wake-up signal. For example, the letter x represents the number of DRX periods corresponding to one wake-up signal, and the value of x can be a positive integer such as 1 or 2. The information indicating the duration is the value indicating whether the wake-up signal needs to page the terminal device within a certain duration. For example, if the duration represents 3 subframes, then the wake-up signal needs to page the terminal device within 3 subframes. In the embodiments of this application, the usage threshold of the wake-up signal refers to the eDRX period threshold for using the wake-up signal. The value of the usage threshold can be a time unit such as seconds or milliseconds, or it can be a subframe, system frame, superframe, etc. that can reflect time.

[0179] In some embodiments of this application, step S501, where the core network device receives configuration information from the wake-up signal sent by the network device, includes:

[0180] The core network equipment receives an interface establishment request message from the network equipment. This message carries configuration information for the wake-up signal; or...

[0181] The core network equipment receives configuration update messages from the network equipment, and the configuration update messages carry configuration information for the wake-up signal.

[0182] The core network device can receive interface establishment request messages from network devices. These messages are sent by the network device when establishing an interface between them. The core network device carries configuration information for the wake-up signal. For example, a new field can be added to the interface establishment request message to carry this configuration information, or an expandable field within the message can be used. The core network device can also receive configuration update messages from network devices. These messages indicate a notification sent by the network device to the core network device when it has a configuration update. Again, a new field can be added to the configuration update message to carry this configuration information, or an expandable field within the message can be used.

[0183] In some embodiments of this application, the information processing method provided in this application may further include the following steps:

[0184] S502. The core network equipment determines the PTW length of the terminal equipment based on the configuration information of the wake-up signal. The PTW length is greater than the time interval between two adjacent wake-up signals.

[0185] The core network equipment can determine the PTW length of the terminal equipment based on the configuration information of the wake-up signal. The PTW length determined by the core network equipment is greater than the time interval between two adjacent wake-up signals. That is, there is more than one wake-up signal within a PTW, thereby avoiding the paging delay caused by having to wait for the next eDRX cycle due to missing a wake-up opportunity, and improving the utilization of network resources.

[0186] In some embodiments of this application, the configuration information of the wake-up signal includes information indicating the period of the wake-up signal. Step S502, the core network device determines the PTW length of the terminal device based on the configuration information of the wake-up signal, including:

[0187] The core network equipment determines the PTW length based on the period of the wake-up signal, and the PTW length is greater than the period of the wake-up signal.

[0188] The core network equipment determines the PTW length based on the period of the wake-up signal. The PTW length determined by the core network is greater than the period of the wake-up signal. For example, the PTW length can be greater than or equal to 'a' times the period of the wake-up signal. Thus, there can be more than 'a' wake-up signals within one PTW length. The value of 'a' can be a positive integer. For instance, if 'a' is 2, the core network equipment calculates that there are 2 wake-up signals within the PTW length. Similarly, if 'a' is 3, the core network equipment calculates that there are 3 wake-up signals within the PTW length.

[0189] In some embodiments of this application, the configuration information of the wake-up signal includes information indicating the correspondence between the wake-up signal and the discontinuous reception DRX period. Step S502, the core network device determines the PTW length of the terminal device based on the configuration information of the wake-up signal, including:

[0190] The core network equipment determines the correspondence between the wake-up signal and the discontinuous reception DRX cycle as follows: one wake-up signal corresponds to x DRX cycles, where x is a positive integer;

[0191] The core network equipment determines the PTW length based on the correspondence between the wake-up signal and the discontinuous reception DRX period. The PTW length is greater than the result obtained by multiplying x by the value of the DRX period.

[0192] The core network equipment determines the PTW length based on the correspondence between wake-up signals and discontinuous reception DRX cycles. One wake-up signal corresponds to x DRX cycles, where x is a positive integer, for example, x can be 2. The PTW length determined by the core network is greater than x multiplied by the value of the DRX cycle. For example, the PTW length can be greater than or equal to 'a' multiplied by x, then multiplied by the value of the DRX cycle. Since x multiplied by the DRX cycle corresponds to one wake-up signal, there can be more than 'a' wake-up signals within one PTW length. The value of 'a' can be a positive integer. For example, if 'a' is 2, the core network equipment calculates that there are 2 wake-up signals within the PTW length. Similarly, if 'a' is 3, the core network equipment calculates that there are 3 wake-up signals within the PTW length.

[0193] In some embodiments of this application, the configuration information of the wake-up signal includes information indicating the duration. Step S502, the core network device determines the paging time window (PTW) length of the terminal device based on the configuration information of the wake-up signal, including:

[0194] The core network equipment determines the PTW length based on the duration information, and the PTW length is greater than the duration value.

[0195] The core network equipment determines the PTW length based on the duration of the wake-up signal. The PTW length determined by the core network is greater than the wake-up signal duration. For example, the PTW length can be greater than or equal to 'a' times the wake-up signal duration. Thus, there can be more than 'a' wake-up signals within a PTW length. The value of 'a' can be a positive integer. For instance, if 'a' is 2, the core network equipment calculates that there are 2 wake-up signals within the PTW length. Similarly, if 'a' is 3, the core network equipment calculates that there are 3 wake-up signals within the PTW length.

[0196] In some embodiments of this application, the information processing method provided in this application may further include:

[0197] The core network equipment sends a paging message to the network equipment. The paging message includes the eDRX cycle.

[0198] The core network equipment can send the determined eDRX cycle of the terminal equipment to the network equipment, so that the network equipment can receive the eDRX cycle. The network equipment can then compare the eDRX cycle with the threshold for using the wake-up signal to determine the relationship between the two and then decide whether to use the wake-up signal.

[0199] In some embodiments of this application, the information processing method provided in this application may further include the following steps:

[0200] The core network equipment sends information indicating the PTW length to the terminal equipment; and / or,

[0201] The core network equipment sends a paging message to the network equipment for the terminal equipment. The paging message includes information indicating the PTW length.

[0202] The core network equipment can configure the PTW (Plan-Off Threshold) length of the terminal equipment to the terminal equipment. For example, the core network equipment can send the PTW length of the terminal equipment to the terminal equipment via transparent transmission. This allows the terminal equipment to determine whether it needs to listen for a wake-up signal or a paging signal within that PTW length. The core network equipment can also send paging messages of the terminal equipment to the network equipment. These paging messages include information indicating the PTW length. This allows the network equipment to determine whether to send a wake-up signal or a paging signal within that PTW length.

[0203] As illustrated by the foregoing embodiments, in this application embodiment, the core network device can receive configuration information of a wake-up signal from a network device. The wake-up signal indicates whether to page the terminal device within a certain period of time, and the configuration information indicates the time interval between two adjacent wake-up signals. Therefore, this application embodiment can realize the transmission of wake-up signal configuration information. After receiving the wake-up signal configuration information, the core network device can complete the paging configuration of the terminal device based on the configuration parameters, enabling the terminal device to save paging power consumption by listening to the wake-up signal and improve the utilization rate of network resources.

[0204] The foregoing embodiments described the information processing method provided in this application from the perspective of a network device. Next, another information processing method performed by a network device will be introduced. Please refer to [link to relevant documentation]. Figure 6 As shown in the figure, this application provides an information processing method, including:

[0205] S601, The network device determines the threshold for using the wake-up signal.

[0206] In this embodiment, the wake-up signal usage threshold refers to a threshold value for whether the wake-up signal is valid. The wake-up signal can be used to optimize terminal devices with short paging cycles but low paging frequencies. Configuring the wake-up signal usage threshold can take into account the currently available network resources and the paging cycles of terminal devices in the network. For example, the usage threshold can be configured based on the network resource situation of the network device. If there are more network resources, the usage threshold value can be configured to be larger; if there are fewer network resources, the usage threshold value can be configured to be smaller. Alternatively, it can be configured based on the eDRX cycle distribution of terminal devices in the network. If b% of the terminal eDRX cycles are less than c, the usage threshold can be configured to c. The values ​​of b and c can be determined according to the scenario. The network device and the terminal device can determine whether to use the wake-up signal based on the wake-up signal usage threshold. If the network device determines to use the wake-up signal, it will send the wake-up signal to the terminal device. If the terminal device determines to use the wake-up signal, it will listen for the wake-up signal.

[0207] S602, Threshold for network devices to send wake-up signals to terminal devices.

[0208] In this embodiment of the application, after the network device obtains the usage threshold of the wake-up signal, the network device sends the usage threshold of the wake-up signal to the terminal device, for example, by sending the usage threshold of the wake-up signal through the air interface between the network device and the terminal device.

[0209] In some embodiments of this application, an information processing method further includes:

[0210] The network device receives a paging message from the core network device. The paging message includes the eDRX cycle.

[0211] When a network device determines that the eDRX period is less than or equal to the threshold for using the wake-up signal, the network device sends a wake-up signal to the terminal device.

[0212] The core network device can send the determined eDRX cycle of the terminal device to the network device. The network device can receive the eDRX cycle and compare it with the wake-up signal usage threshold to determine the relationship between the two. Then, it can decide whether to use the wake-up signal. When the eDRX cycle is less than or equal to the wake-up signal usage threshold, the network device sends a wake-up signal to the terminal device. The network device can wake up the terminal device through this wake-up signal. The network device can then page the terminal device. If the terminal device does not hear the wake-up signal, it will not listen for paging messages from the network device until it hears the wake-up signal, thus saving network resources.

[0213] In some embodiments of this application, the usage threshold for a network device to send a wake-up signal to a terminal device includes:

[0214] Network devices send wake-up signals via broadcast to trigger usage thresholds.

[0215] In this method, network devices can send broadcast messages to terminal devices, carrying a wake-up signal usage threshold. Upon receiving this broadcast message, all terminal devices within the network's cell can determine the wake-up signal usage threshold. By broadcasting the wake-up signal usage threshold, network devices effectively improve information transmission efficiency.

[0216] In some embodiments of this application, an information processing method further includes:

[0217] The network device receives a paging message from the terminal device of the core network device. The paging message includes information indicating the PTW length of the terminal device. The PTW length is greater than the time interval between two adjacent wake-up signals.

[0218] The core network equipment can configure the PTW length of the terminal equipment to the terminal equipment. For example, the core network equipment can send the PTW length of the terminal equipment to the terminal equipment in a transparent manner, so that the terminal equipment can determine whether it needs to listen for the wake-up signal or the paging signal within the PTW length.

[0219] As illustrated by the foregoing embodiments, in this application embodiment, the network device sends a usage threshold for the wake-up signal to the terminal device. Therefore, this application embodiment can realize the transmission of the wake-up signal usage threshold. After receiving the wake-up signal usage threshold, the terminal device can determine whether to listen for the wake-up signal based on the usage threshold and the eDRX period. When the eDRX period of the terminal device is less than or equal to the wake-up signal usage threshold, the terminal device listens for the wake-up signal, thereby saving paging power consumption and improving the utilization rate of network resources.

[0220] The foregoing embodiments described the information processing method provided in this application from the perspective of network devices and core network devices. The following description describes the information processing method provided in this application from the perspective of terminal devices. Please refer to [link to relevant documentation]. Figure 7 As shown in the figure, this application provides an information processing method, including:

[0221] S701, the threshold for terminal devices to receive wake-up signals from network devices.

[0222] In this embodiment of the application, the terminal device receives the usage threshold of the wake-up signal sent by the network device. For example, the usage threshold of the wake-up signal can be received through the air interface between the network device and the terminal device.

[0223] In some embodiments of this application, the usage threshold for the terminal device to receive a wake-up signal from the network device includes:

[0224] The terminal device receives the wake-up signal via a broadcast message sent by the network device, which is a usage threshold.

[0225] In this method, network devices can send broadcast messages to terminal devices, carrying a wake-up signal usage threshold. Upon receiving this broadcast message, all terminal devices within the network's cell can determine the wake-up signal usage threshold. By broadcasting the wake-up signal usage threshold, network devices effectively improve information transmission efficiency.

[0226] S702. When the eDRX period of the terminal device is less than or equal to the threshold for using the wake-up signal, the terminal device listens for the wake-up signal.

[0227] The terminal device can determine whether its eDRX cycle is less than or equal to the usage threshold. If the terminal device's eDRX cycle is less than or equal to the usage threshold, it will first listen for the wake-up signal and then listen for the paging message.

[0228] In some embodiments of this application, an information processing method further includes:

[0229] When the eDRX cycle of the terminal device is greater than the threshold for using the wake-up signal, the terminal device listens for paging messages from the network device.

[0230] Specifically, if the eDRX cycle of the terminal device exceeds a threshold, it will directly listen for paging messages. Directly listening for paging messages means that the terminal device no longer listens for wake-up signals, but instead listens for paging messages according to the PTW length and eDRX cycle.

[0231] In some embodiments of this application, an information processing method further includes:

[0232] When a terminal device detects a wake-up signal, it listens for paging messages from network devices for the duration indicated by the wake-up signal.

[0233] Specifically, when the eDRX period is determined to be less than or equal to the threshold for using the wake-up signal, the network device sends a wake-up signal to the terminal device. The network device can wake up the terminal device through this wake-up signal. Then, the network device can page the terminal device again. If the terminal device does not hear the wake-up signal, it will not listen for the paging message from the network device until it hears the wake-up signal, thereby saving network resources.

[0234] In some embodiments of this application, an information processing method further includes:

[0235] The terminal device receives information from the core network device indicating the length of the PTW, and the length of the PTW is greater than the time interval between two adjacent wake-up signals.

[0236] The core network equipment can configure the PTW length of the terminal equipment to the terminal equipment. For example, the core network equipment can send the PTW length of the terminal equipment to the terminal equipment in a transparent manner, so that the terminal equipment can determine whether it needs to listen for the wake-up signal or the paging signal within the PTW length.

[0237] As illustrated by the foregoing embodiments, in this application embodiment, the terminal device receives a usage threshold for the wake-up signal from the network device. When the eDRX period of the terminal device is less than or equal to the usage threshold of the wake-up signal, the terminal device listens for the wake-up signal. Therefore, this application embodiment can realize the transmission of the wake-up signal usage threshold. After receiving the wake-up signal usage threshold, the terminal device can determine whether to listen for paging messages based on the usage threshold and the eDRX period. When the eDRX period of the terminal device is less than or equal to the usage threshold of the wake-up signal, the terminal device listens for the wake-up signal, thereby saving paging power consumption and improving the utilization rate of network resources.

[0238] Next, regarding Figures 4 to 7 The application scenario of the information processing method shown is illustrated with examples. The following examples use a base station as the network device, an MME as the core network device, and a UE as the terminal device. In this embodiment, the base station can coordinate with the core network device on the configuration information of the PTW length and wake-up signal. The base station controls the terminal device using the wake-up signal through configuration, thereby ensuring terminal gain. One application scenario of the information processing method provided in this embodiment mainly includes the following process:

[0239] S11. The base station transmits configuration information of the wake-up signal in the cell via system broadcast. The configuration information may include at least one of the following: the period of the wake-up signal, the starting position of the wake-up signal within a period, and the duration.

[0240] S12. The base station sends paging configuration information in the cell, including DRX cycle, through system broadcast.

[0241] S13. The base station sends the DRX periodic configuration information of this cell to the core network equipment.

[0242] S14. If the base station has configured a wake-up signal in this cell, it sends the configuration information of the wake-up signal to the MME. This configuration information is used to indicate the time interval between two wake-up signals.

[0243] For example, the configuration information of the wake-up signal can include the period of the wake-up signal, which can be a time unit such as seconds or milliseconds, or other units that can reflect the length of time such as time slots, symbols, subframes, system frames, and superframes.

[0244] For example, the configuration information for the wake-up signal can include the correspondence between the wake-up signal and the DRX cycle of the base station. For instance, a wake-up signal can indicate whether the base station will page the terminal within the next x DRX cycles, where x is a positive integer.

[0245] It should be noted that the base station can send the wake-up signal configuration information to the core network equipment in multiple processes or messages. For example, when establishing the interface between the base station and the core network, the wake-up signal configuration information can be sent to the core network equipment in the corresponding interface establishment message (such as the S1 interface establishment request message) or in the base station configuration update message during the base station configuration update process after the interface establishment is completed.

[0246] S15. The MME configures the PTW length of the terminal device according to the wake-up signal configuration information of the base station to ensure that there is more than one wake-up signal within one PTW. For example, the PTW length can be greater than or equal to a * wake-up signal period, where * represents multiplication. In this way, there can be more than a wake-up signals within one PTW length, where a is a positive integer. Alternatively, the PTW length can be greater than or equal to a * x * DRX period, which also allows for more than a wake-up signals within one PTW length.

[0247] The following example illustrates the application scenario of the wake-up signal usage threshold, mainly including the following process: First, the base station broadcasts configuration information such as the wake-up signal period, position within the period, and duration. Then, the base station broadcasts the usage threshold for the wake-up signal, which can be in time units such as seconds or milliseconds, or in time-reflecting subframes, system frames, or superframes. During paging: The base station first receives the paging message from the core network equipment, obtains the terminal device ID and eDRX period. If the terminal device's eDRX period is greater than the wake-up signal usage threshold configured by the base station, the terminal is paged using the conventional paging method, i.e., a P-RNTI scrambled PDCCH is sent on the corresponding PO. Otherwise, based on its own wake-up signal configuration information and the terminal device ID, the terminal device's wake-up signal is sent at the corresponding position. After waking up in each eDRX period, if the terminal's own eDRX period is greater than the wake-up signal usage threshold broadcast by the base station, it directly listens for conventional paging, i.e., according to the base station's paging configuration, the P-RNTI scrambled PDCCH is decoded on the corresponding PO. Otherwise, the location of the wake-up signal is determined based on the configuration information of the base station's wake-up signal and its own ID, and the wake-up signal is monitored.

[0248] As illustrated by the examples in the foregoing embodiments, the MME can configure the PTW length of the terminal device according to the configuration information of the base station's wake-up signal, thereby ensuring that there are multiple opportunities to wake up the terminal device within a PTW.

[0249] The following describes in detail the early data transmission provided in this application embodiment. Early data transmission refers to transmitting data before establishing a connection, compared to traditional connection establishment transmission, thus representing an earlier transmission scheme. Early data transmission can also refer to transmitting data during random access. Traditional data transmission involves first entering the connected state through random access, then transmitting data in the connected state, and finally releasing the connection. However, in this application embodiment, the early data transmission process allows the terminal to transmit uplink data during random access. If the data is small, entering the connected state is not necessary, and the data transmission process ends together with the random access process. In the early data transmission process, the first step is to configure dedicated random access resources for early data transmission via broadcast by the base station. These random access resources may include random access time-frequency resources. The early data transmission process can begin when the terminal device sends a preamble. In this application embodiment, if the network device configures dedicated random access resources for early data transmission in the broadcast, it indicates that the current network supports early data transmission services.

[0250] A key characteristic of the Internet of Things (IoT) is the diversity of terminals. Different terminals have different functions, different data transmission requirements, and may consume different network resources. For example, NB-IoT and MTC have at least two types of terminals: those using control plane (CP) optimized mode and those using user plane (UP) optimized mode.

[0251] CP optimization mode refers to an IoT transmission scheme that transmits data within the signaling bearer. Traditional broadband service transmission first establishes a control signaling bearer, then establishes a user data transmission bearer, and the data is transmitted within the user data transmission bearer. However, for small data transmission scenarios in IoT, the service data is actually very small, but establishing or releasing control signaling and user data bearers for such a small amount of data incurs significant overhead. Transmitting small data directly within the control signaling bearer avoids the need to establish and release user data bearers, resulting in higher efficiency.

[0252] The advantages of CP (Content Optimization) mode are its simplicity and high efficiency. However, since data transmission occurs while control is being carried out, the performance (latency, reliability) of data transmission is relatively lower, making it suitable only for simpler scenarios. For some IoT services with slightly higher requirements, CP mode is too simplistic and unsuitable. Therefore, UP (Upload Optimization) mode, as a traditional optimization method that uses user data as the carrier, primarily involves simplifying processes, such as replacing release processes with suspension processes and reducing the overhead of each access. It is more suitable for IoT small data packet transmission services with higher requirements.

[0253] In this embodiment, the network device can implicitly indicate that it supports early data transmission services by configuring dedicated random access resources for early data transmission in a broadcast. Furthermore, it can individually indicate whether early data transmission is supported for different types of terminal devices. This embodiment allows the network device to individually support early data transmission for at least one type of terminal device. Please refer to... Figure 8 The diagram shown illustrates another interaction process between network devices, terminal devices, and core network devices according to an embodiment of this application. The information processing method provided in this embodiment mainly includes the following processes:

[0254] S21. The network device determines the types of data early transmission terminals supported by the network device.

[0255] Among them, the data early transmission terminal type includes at least one of the following: terminal equipment using user plane UP optimization mode for data early transmission, or terminal equipment using control plane CP optimization mode for data early transmission.

[0256] In some embodiments of this application, the network device determines the types of early data transmission terminals supported by the network device, including:

[0257] The network device determines that it supports terminal devices using UP optimization mode for early data transmission.

[0258] The network device can support early data transmission for terminal devices using UP optimization mode. For details on UP optimization mode, please refer to the description of the aforementioned embodiments. The type of terminal device that the network device supports for early data transmission can be determined by the network device's configuration parameters.

[0259] In some embodiments of this application, the network device determines the types of early data transmission terminals supported by the network device, including:

[0260] The network device determines that it supports terminal devices using CP optimization mode for early data transmission.

[0261] Among them, the network device can support terminal devices using CP optimization mode to perform early data transmission. For a detailed description of CP optimization mode, please refer to the description of the foregoing embodiments. The type of terminal device that the network device supports for early data transmission can be determined by the configuration parameters of the network device.

[0262] In some embodiments of this application, the network device determines the types of early data transmission terminals supported by the network device, including:

[0263] The network device determines that it simultaneously supports early data transmission for terminal devices using both UP optimization mode and CP optimization mode.

[0264] The network device can support both UP-optimized and CP-optimized terminal devices for early data transmission. For details on UP-optimized and CP-optimized modes, please refer to the description of the foregoing embodiments. The type of terminal device that supports early data transmission can be determined by the network device's configuration parameters.

[0265] S22. The network device sends information about the data transmission terminal types supported by the network device to the terminal device.

[0266] In this embodiment, after the network device determines the data early transmission terminal type supported by the network device, the network device sends information about the data early transmission terminal type supported by the network device to the terminal device. The terminal device can then receive this information and determine the data early transmission terminal type supported by the network device.

[0267] Furthermore, in some embodiments of this application, when the network device determines that it supports early data transmission using the UP optimization mode, step S22 involves the network device sending information about the early data transmission terminal types supported by the network device to the terminal device, including:

[0268] The network device sends information to the terminal device indicating the random access resources used for early data transmission. This information instructs the network device to support early data transmission by the terminal device using UP optimization mode; or...

[0269] The network device sends information to the terminal device indicating the random access resources used for early data transmission, and information indicating that the network device supports the terminal device to perform early data transmission using the UP optimization mode.

[0270] The information indicating the random access resources used for early data transmission refers to the resource configuration information of the random access resources dedicated to early data transmission broadcast by the network device. By indicating the random access resources used for early data transmission, the network device can be instructed to support terminal devices using the UP optimization mode for early data transmission. Thus, by parsing the information indicating the random access resources used for early data transmission, the terminal device can determine that the network device supports terminal devices using the UP optimization mode for early data transmission.

[0271] For example, the information indicating that the network device supports terminal devices using the UP optimization mode for early data transmission can be a specific indication message. This indication message can be independent of the information indicating the random access resources used for early data transmission. The network device sends the information indicating that the network device supports terminal devices using the UP optimization mode for early data transmission to the terminal device. Thus, by parsing the information indicating that the network device supports terminal devices using the UP optimization mode for early data transmission, the terminal device can determine that the network device supports terminal devices using the UP optimization mode for early data transmission.

[0272] In some embodiments of this application, the network device sends information about the data early transmission terminal types supported by the network device to the terminal device, including:

[0275] Among them, information indicating that the network device supports terminal devices using UP optimization mode and information indicating random access resources for early data transmission are used to instruct the network device to support terminal devices using UP optimization mode for early data transmission.

[0276] In the foregoing embodiments of this application, "network device supports terminal devices using UP optimization mode" means that the network device supports terminal devices using UP optimization mode. That is, the information sent by the network device indicating that it supports terminal devices using UP optimization mode only indicates that the network device supports terminal devices using UP optimization mode. If the network device also sends information indicating random access resources for early data transmission, and if the terminal device receives both the information indicating that the network device supports terminal devices using UP optimization mode and the information indicating random access resources for early data transmission, then the terminal device can determine that the network device supports terminal devices using UP optimization mode for early data transmission based on these two pieces of information.

[0277] In other embodiments of this application, when the network device determines that it supports early data transmission using the CP optimization mode, step S22 involves the network device sending information about the early data transmission terminal types supported by the network device to the terminal device, including:

[0278] The network device sends information to the terminal device indicating the random access resources used for early data transmission. This information instructs the network device to support early data transmission by the terminal device using CP optimization mode; or,

[0279] The network device sends information to the terminal device indicating the random access resources used for early data transmission, and information indicating that the network device supports the terminal device to perform early data transmission using the CP optimization mode.

[0280] The information indicating random access resources used for early data transmission refers to the resource configuration information of random access resources dedicated to early data transmission broadcast by the network device. By indicating the information indicating random access resources used for early data transmission, the network device can be instructed to support terminal devices using the CP optimization mode for early data transmission. Thus, by parsing the information indicating random access resources used for early data transmission, the terminal device can determine that the network device supports terminal devices using the CP optimization mode for early data transmission.

[0281] For example, the information indicating that the network device supports terminal devices using the CP optimization mode for early data transmission can be a specific indication message. This indication message can be independent of the information indicating random access resources used for early data transmission. The network device sends the information indicating that the network device supports terminal devices using the CP optimization mode for early data transmission to the terminal device. Thus, by parsing the information indicating that the network device supports terminal devices using the CP optimization mode for early data transmission, the terminal device can determine that the network device supports terminal devices using the CP optimization mode for early data transmission.

[0282] In some embodiments of this application, the network device sends information about the data early transmission terminal types supported by the network device to the terminal device, including:

[0283] The network device sends a message to the terminal device indicating that the network device supports the terminal device using the CP optimization mode;

[0284] The network device sends information to the terminal device indicating the random access resources used for early data transmission;

[0285] Among them, information indicating that the network device supports terminal devices using the CP optimization mode and information indicating random access resources for early data transmission are used to instruct the network device to support terminal devices using the CP optimization mode for early data transmission.

[0286] In the foregoing embodiments of this application, "network device supports terminal devices using CP optimization mode" means that the network device supports terminal devices using CP optimization mode. That is, the information sent by the network device indicating that it supports terminal devices using CP optimization mode only indicates that the network device supports terminal devices using CP optimization mode. If the network device also sends information indicating random access resources for early data transmission, and if the terminal device receives both the information indicating that the network device supports terminal devices using CP optimization mode and the information indicating random access resources for early data transmission, then the terminal device can determine that the network device supports terminal devices using CP optimization mode for early data transmission based on these two pieces of information.

[0287] In other embodiments of this application, when the network device determines that it simultaneously supports data early transmission using both UP-optimized and CP-optimized terminal devices, step S22 involves the network device sending information about the data early transmission terminal types supported by the network device to the terminal device, including:

[0288] The network device sends information to the terminal device indicating the random access resources used for early data transmission. This information instructs the network device to simultaneously support early data transmission for terminal devices using both UP-optimized mode and CP-optimized mode; or,

[0289] The network device sends information to the terminal device indicating the random access resources used for early data transmission, and information indicating that the network device simultaneously supports early data transmission for terminal devices using both UP optimization mode and CP optimization mode.

[0290] The information indicating the random access resources used for early data transmission refers to the resource configuration information of the random access resources dedicated to early data transmission broadcast by the network device. By indicating the random access resources used for early data transmission, the network device can be instructed to simultaneously support terminal devices using UP optimization mode and terminal devices using CP optimization mode for early data transmission. Thus, by parsing the information indicating the random access resources used for early data transmission, the terminal device can determine that the network device simultaneously supports terminal devices using UP optimization mode and terminal devices using CP optimization mode for early data transmission.

[0291] For example, the information indicating that a network device simultaneously supports early data transmission for terminal devices using both UP-optimized mode and CP-optimized mode can be a specific indication message. This indication message can be independent of the information indicating random access resources used for early data transmission. The network device sends this information to the terminal device, and the terminal device can then determine that the network device simultaneously supports early data transmission for both UP-optimized and CP-optimized modes by parsing the information.

[0292] In some embodiments of this application, the network device sends information about the data early transmission terminal types supported by the network device to the terminal device, including:

[0293] The network device sends information to the terminal device indicating the random access resources used for early data transmission, and information indicating that the network device supports the terminal device in using UP-optimized mode for early data transmission. The information indicating the random access resources used for early data transmission is used to instruct the network device to support the terminal device in using CP-optimized mode for early data transmission, or...

[0294] The network device sends information to the terminal device indicating random access resources for early data transmission and information indicating that the network device supports the terminal device to perform early data transmission using the CP optimization mode. The information indicating random access resources for early data transmission is used to instruct the network device to support the terminal device to perform early data transmission using the UP optimization mode.

[0295] In some embodiments of this application, the network device sends information about the data early transmission terminal types supported by the network device to the terminal device, including:

[0296] The network device sends information to the terminal device about the data transmission terminal type supported by the network device within a specific range. The specific range includes at least one of the following: the network device's cell, carrier, or coverage level.

[0297] The specific range can be predefined by the protocol or indicated by the network device to the terminal device, which will not be elaborated here. If the network device determines the types of data early transmission terminals supported within a specific range, the terminal device also needs to determine whether it meets the requirements of that specific range when determining which data early transmission terminal type the network device supports. For example: Determine the carrier used to initiate data early transmission. This can be randomly selected from the available carriers broadcast by the base station or selected according to its own ID. For example, the carrier ID used could be the terminal ID modulo the number of carriers available for data early transmission, where mod represents the remainder. If the base station indicates support for data early transmission on this carrier for the terminal's category, then the data early transmission procedure is used. Another example is determining the coverage level for initiating data early transmission. The terminal determines the coverage level based on its own measured link quality and the correspondence between link quality and coverage levels broadcast by the base station, such as several thresholds. If the base station indicates support for data early transmission on this coverage level for the terminal's category, then the data early transmission procedure is used.

[0298] S23. The terminal device determines the data early transmission terminal type supported by the network device. The data early transmission terminal type includes at least one of the following: a terminal device using the user plane UP optimization mode for data early transmission, or a terminal device using the control plane CP optimization mode for data early transmission.

That is, the information sent by the network device indicating support for terminal devices using UP optimization mode only indicates the network device's support for terminal devices using UP optimization mode. If the network device also sends information indicating random access resources for early data transmission, and if the terminal device receives both the information indicating support for UP optimization mode and the information indicating random access resources for early data transmission, the terminal device can determine that the network device supports terminal devices using UP optimization mode for early data transmission based on these two pieces of information.

[0326] The terminal device determines whether to use the data early transmission mode based on the data early transmission terminal type supported by the network device and the transmission type of the terminal device.

[0327] The specific range can be predefined by the protocol or indicated by the network device to the terminal device, which will not be elaborated here. If the network device determines the types of data early transmission terminals supported within a specific range, the terminal device also needs to determine whether it meets the requirements of that specific range when determining which data early transmission terminal type the network device supports.

For example, the carrier ID used could be the terminal ID modulo the number of carriers available for data early transmission, where mod represents the remainder. If the base station indicates support for data early transmission on this carrier for the terminal's category, then the data early transmission procedure is used. Another example is determining the coverage level for initiating data early transmission. The terminal determines the coverage level based on its own measured link quality and the correspondence between link quality and coverage levels broadcast by the base station, such as several thresholds. If the base station indicates support for data early transmission on this coverage level for the terminal's category, then the data early transmission procedure is used.

[0328] Next, regarding Figure 8 The application scenario of the information processing method shown is illustrated with examples. The following examples use a base station as the network device and a UE as the terminal device. In this embodiment, the base station can coordinate with the core network equipment to configure PTW length and wake-up signal information. The base station controls the terminal device using the wake-up signal through configuration, thereby ensuring terminal gain. One application scenario of the information processing method provided in this embodiment mainly includes the following process:

[0329] S31. The base station configures random access resources for data early transmission at different coverage levels (i.e., greater than or equal to one coverage level) for different carriers via broadcast, including the period of occurrence of random access resources, the time domain position of resources in each period, available subcarrier IDs, and the number of times the terminal sends the preamble.

[0330] S32. The base station broadcasts the terminal types that are supported for regular data transmission. Here, the regular data transmission indication is that the terminal device adopts CP optimization mode or UP optimization mode.

[0331] S33. The base station indicates the types of early data transmission terminals it supports by broadcasting the aforementioned random access resources dedicated to early data transmission and / or specific indication information. This can mainly include the following implementation methods:

[0332] 1. Using configuration information of random access resources and information indicating that the base station supports terminal equipment using UP optimization mode: If the base station broadcasts random access resources dedicated to early data transmission, it means that the base station supports terminals in CP optimization mode to perform early data transmission. Then, through special indication information, it indicates whether terminals in UP optimization mode are supported to perform early data transmission.

[0333] 2. Using configuration information of random access resources and information indicating that the base station supports terminal equipment using CP optimization mode: If the base station broadcasts random access resources dedicated to data early transmission, it means that the base station supports terminals in UP optimization mode to perform data early transmission process; through special indication information, it indicates whether terminals in CP optimization mode are supported to perform data early transmission process.

[0334] 3. Configuration information using only random access resources: If the base station broadcasts random access resources dedicated to early data transmission, it means that the base station supports early data transmission for terminals in both CP-optimized mode and UP-optimized mode.

[0335] 4. Using configuration information for random access resources and indication information for regular data transmission: If the base station broadcasts random access resources dedicated to early data transmission, it indicates that the base station supports the same type of terminal that supports early data transmission as indicated in step S32.

[0336] It should be noted that the above indication of the terminal types supporting early data transmission can be a cell-level indication, indicating the terminal types supporting early data transmission in the current cell. Alternatively, it can be a terminal type supporting early data transmission on a specific carrier and / or coverage level. If the latter, it needs to be indicated separately for each carrier and / or each coverage level.

[0337] For example, the random access resource configuration for early data transmission in step S31 is as follows: Carrier 1 supports resources of coverage level 1, coverage level 2, and coverage level 3. Carrier 2 supports resources of coverage level 1 and coverage level 2.

[0338] If the above indication supports early data transmission at the cell level, such as CP supporting it but UP not supporting it, then the effect is as follows:

[0339] Carrier 1:

[0340] Resources with coverage level 1: CP supports them, UP does not.

[0341] Resources with coverage level 2: CP supports them, UP does not.

[0342] Resources with coverage level 3: CP supports them, UP does not.

[0343] Carrier 2:

[0344] Resources with coverage level 1: CP supports them, UP does not.

[0345] Resources with coverage level 2: CP supports them, UP does not.

[0346] The above-mentioned terminal types that support early data transmission can also be carrier-level indicators, meaning that each carrier is indicated separately, and each carrier has different support for CP and UP, for example:

[0347] Carrier 1: Supported by CP, not supported by UP.

[0348] Resources with coverage level 1: CP supports them, UP does not.

[0349] Resources with coverage level 2: CP supports them, UP does not.

[0350] Resources with coverage level 3: CP supports them, UP does not.

[0351] Carrier 2: CP supported, UP supported.

[0352] Resources covering Level 1: CP supported, UP supported.

[0353] Resources covering Level 2: CP supported, UP supported.

[0354] The terminal types supporting early data transmission indicated above can also be individually indicated for resources at each coverage level on each carrier. The random resources at each coverage level on each carrier are different for CP and UP, for example:

[0355] Carrier 1:

[0356] Resources with coverage level 1: CP supports them, UP does not.

[0357] Resources covering Level 2: CP supported, UP supported.

[0358] Coverage Level 3 resources: CP supported, UP supported.

[0359] Carrier 2:

[0360] Resources with coverage level 1: CP does not support them, UP does.

[0361] Resources with coverage level 2: CP does not support them, UP does.

[0362] S34. The terminal decides whether to use early data transmission when there is a need for early data transmission, based on the support for early data transmission terminal types indicated by the base station and the transmission type of the terminal device itself.

[0363] For example, if the base station indication is a cell-level indication: if the terminal needs to use early data transmission, and the base station indication supports early data transmission for the terminal's category, then the early data transmission procedure is used.

[0364] If the base station indication is for each carrier and / or each coverage level, it may include the following:

[0365] For example, the carrier to be used to initiate early data transmission is determined by randomly selecting from the available carriers broadcast by the base station or by selecting according to its own ID. For example, the carrier ID used is the number of carriers available for early data transmission modulo the terminal ID. If the base station indicates that it supports early data transmission on this carrier for the terminal's category, then the early data transmission procedure is used.

[0366] For example, to determine the coverage level for initiating early data transmission, the terminal determines the coverage level based on its own measured link quality and the correspondence between the link quality and coverage level broadcast by the base station, such as several thresholds. If the base station indicates that it supports early data transmission of the terminal's category at this coverage level, then the early data transmission procedure is used.

[0367] As illustrated by the examples above, the support of base station broadcasting for data transmission terminal types is such that only qualified terminal devices will use the corresponding data transmission characteristics.

[0434] Figure 12 This is a schematic diagram of the structure of a terminal device provided in an embodiment of this application. This terminal device is applicable to... Figure 1 The system shown executes the functions of the terminal device in the above method embodiments. For ease of explanation, Figure 12 Only the main components of the terminal device are shown. For example... Figure 12 As shown, the terminal device 40 includes a processor, memory, control circuit, antenna, and input / output devices. The processor is mainly used to process communication protocols and communication data, control the entire terminal device, execute software programs, and process the data of the software programs. For example, it supports the terminal device in performing the actions described in the above method embodiments, such as setting a threshold for receiving wake-up signals and determining whether to listen for wake-up signals based on the threshold and the eDRX cycle. The memory is mainly used to store software programs and data, such as storing the wake-up signal usage threshold described in the above embodiments. The control circuit is mainly used for converting baseband signals to radio frequency signals and processing radio frequency signals. The control circuit and antenna together can also be called a transceiver, mainly used for transmitting and receiving radio frequency signals in the form of electromagnetic waves.

[0435] When the terminal device is powered on, the processor can read the software program from the storage unit, interpret and execute the software program's instructions, and process the software program's data. When data needs to be transmitted wirelessly, the processor performs baseband processing on the data to be transmitted and outputs the baseband signal to the radio frequency (RF) circuit. The RF circuit then processes the baseband signal and transmits the RF signal outward as electromagnetic waves through the antenna. When data is sent to the terminal device, the RF circuit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor. The processor converts the baseband signal back into data and processes the data.

The processor 5022 is used to control the base station to perform necessary actions, such as controlling the base station to execute the operation procedures related to the network device in the above method embodiments. The memory 5021 and processor 5022 can serve one or more single boards. That is, each single board can have its own memory and processor, or multiple single boards can share the same memory and processor. Furthermore, each single board can also have necessary circuitry.
