Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular, to a paging method, device and system. Background Art

[0002] Currently, the power consumption of low-power terminal devices when demodulating paging messages during the paging process is high, which affects the working time of the low-power terminal devices. Therefore, how to reduce the power consumption of terminal devices during the paging process is a technical problem that needs to be solved at present. Summary of the invention

[0003] The embodiments of the present application provide a paging method, device, and system, which can reduce the power consumption of terminal equipment during the paging process.

[0004] In order to achieve the above objectives, this application provides the following technical solutions:

[0005] In a first aspect, a paging method is provided, which can be executed by a first terminal device, or by a component of the first terminal device, such as a processor, a chip, or a chip system of the first terminal device, or by a logic module or software that can implement all or part of the first terminal device. The following is an illustration of the method being executed by the first terminal device. The paging method includes: obtaining a first paging message, the first paging message includes a first bit sequence in a second paging message, the second paging message includes a first bit sequence and a second bit sequence, wherein the first bit sequence is used to carry a first type of terminal device identifier, and the first bit sequence and the second bit sequence are used to jointly carry a second type of terminal device identifier; demodulating the first bit sequence in the first paging message to obtain the first type of terminal device identifier.

[0006] In the embodiment of the present application, the first paging message and the second paging message respectively carry different types of terminal device identifiers, and the first paging message includes a partial bit sequence of the second paging message. During the paging process, the terminal device demodulates the first bit sequence from the first paging message to obtain the first type of terminal device identifier, so that the terminal device can obtain the terminal device identifier of the paging message while demodulating fewer bits. Therefore, the terminal device demodulates fewer bits during the paging process, and the power consumption required for the demodulation of the terminal device is also less, thereby reducing the power consumption of the terminal device during the paging process.

[0007] In combination with the above-mentioned first aspect, in a possible implementation method, the first paging message is a paging message obtained by the access network device after intercepting the first bit sequence from the second paging message; or, the first paging message is a paging message obtained by the core network device after intercepting the first bit sequence from the second paging message; or, the first paging message is a paging message selected by the access network device from the first paging message and the second paging message sent by the core network device.

[0008] Based on this, the access network device or the core network device can intercept the first bit sequence from the second paging message to obtain the first paging message. Alternatively, the access network device selects the first paging message from the first paging message and the second paging message sent by the core network device. In this way, different entities can intercept the first paging message from the second paging message in different scenarios.

[0009] In combination with the first aspect above, in a possible implementation manner, obtaining the first paging message includes: receiving the first paging message; or receiving the second paging message and intercepting a first bit sequence from the second paging message to obtain the first paging message.

[0010] Based on this, the terminal device can directly demodulate after receiving the first paging message, or intercept the first paging message from the second paging message for demodulation after receiving the second paging message, thereby reducing the number of bits required for demodulation when the first terminal device demodulates the paging message.

[0011] In combination with the above-mentioned first aspect, in a possible implementation method, intercepting a first bit sequence from a second paging message to obtain a first paging message includes: receiving first indication information, the first indication information is used to indicate at least one of the following: the position and quantity of the first bit sequence in the second paging message, and determining a first preset rule for the first bit sequence; based on the first indication information, intercepting the first bit sequence from the second paging message to obtain the first paging message.

[0012] Based on this, the terminal device can determine the position and quantity of the first bit sequence in the second paging message according to the received first indication information, and then intercept the first bit sequence from the second paging message.

[0013] In combination with the first aspect above, in a possible implementation, intercepting a first bit sequence from a second paging message to obtain a first paging message includes: based on a first preset rule, intercepting the first bit sequence from the second paging message to obtain the first paging message.

[0014] Based on this, the terminal device can directly intercept the first bit sequence from the second paging message according to the preconfigured first preset rule.

[0015] In combination with the above-mentioned first aspect, in a possible implementation method, the first preset rule includes at least one of the following: calculating the position and quantity of the first bit sequence in the second paging message according to a preset calculation method, and querying the position and quantity of the first bit sequence in the second paging message according to a preset record table; wherein the preset record table is used to record the position and quantity of the first bit sequence in the second paging message.

[0016] Based on this, the terminal device can determine the position and quantity of the first bit sequence in the second paging message based on different rules, thereby improving the applicable scenarios in which the terminal device intercepts the first bit sequence from the second paging message.

[0017] In combination with the above-mentioned first aspect, in a possible implementation method, the first bit sequence includes N bits from high to low in the bit positions of the second paging message; N is a positive integer; or, the first bit sequence includes N bits from low to high in the bit positions of the second paging message; or, the first bit sequence includes bits at N preset positions of the second paging message.

[0018] Based on this, the first bit sequence can be arranged in the second paging message using different rules according to specific application scenarios, and the terminal device can intercept the first bit sequence according to the arrangement of the first bit sequence in the second paging message.

[0019] In combination with the above-mentioned first aspect, in a possible implementation manner, the method further includes: receiving second indication information, where the second indication information is used to indicate a type of a paging message; the type of the paging message includes: a first paging message or a second paging message.

[0020] Based on this, the access network device indicates the type of paging message to the terminal device. After determining the type of paging message, the terminal device can demodulate the paging message in a manner corresponding to that type, thereby avoiding the terminal device demodulating the paging message in an incorrect manner after receiving the paging message, resulting in unsuccessful demodulation.

[0021] In combination with the above-mentioned first aspect, in a possible implementation manner, the first type terminal device identifier or the second type terminal device identifier includes: an identifier of the terminal device or an identifier of a terminal device group.

[0022] Based on this, the paging message can carry the identifier of the terminal device, so that the paging message directly pages a specific terminal device, or the paging message can carry the identifier of the terminal device group, so that the paging message can page the terminal devices in the entire terminal device group.

[0023] In combination with the above-mentioned first aspect, in a possible implementation method, the first paging message also includes an identifier of an access and mobility management network element, wherein the identifier of the access and mobility management network element is carried in a third bit sequence in the first paging message; the method also includes: when the access network device type is a first type of access network device, demodulating the third bit sequence in the first paging message to obtain the identifier of the access and mobility management network element included in the first paging message; when the access network device type is a second type of access network device, not demodulating the third bit sequence in the first paging message.

[0024] Based on this, the first paging message may also carry the identifier of the access and mobility management network element. The terminal device may choose whether to demodulate the identifier of the access and mobility management network element in the first paging message according to the access network type. When the terminal device demodulates the identifier of the access and mobility management network element in the first paging message, the terminal device may demodulate the terminal device identifier more accurately. When the terminal device does not demodulate the identifier of the access and mobility management network element in the first paging message, the number of bits used by the terminal device to demodulate the paging message may be reduced, further reducing the power consumption of the terminal device during the paging process.

[0025] In combination with the above first aspect, in a possible implementation manner, the first type of access network device is a shared access network device, and the second type of access network device is a non-shared access network device.

[0026] Based on this, when the access network device is a shared access network device, one cell may correspond to multiple access and mobility management network element identifiers. At this time, if the terminal device does not demodulate the access and mobility management network element identifier in the first paging message, it may cause the terminal device with different access and mobility management network element identifiers but the same terminal device identifier to wake up, resulting in a false alarm. Therefore, when the access network device is a shared access network device, the terminal device demodulates the access and mobility management network element identifier in the first paging message, so that the terminal device can accurately determine the terminal device paged by the paging message, avoiding false alarms.

[0027] In the case where the access network device is a non-shared access network device, one cell corresponds to an access and mobility management network element identifier, and the access and mobility management network element identifiers in the paging message sent by the access network device are the same. At this time, even if the terminal device only demodulates the terminal device identifier, it can correctly determine the terminal device that the paging message is paging. Therefore, the terminal device may not demodulate the access and mobility management network element identifier in the first paging message when the access network device is a non-shared access network device, thereby reducing the number of bits that the terminal device demodulates the paging message, and further reducing the power consumption of the terminal device during the paging process.

[0028] In a second aspect, a paging method is provided, which can be executed by a first terminal device, or by a component of the first terminal device, such as a processor, a chip, or a chip system of the first terminal device, or by a logic module or software that can implement all or part of the first terminal device. The following is an example of the method being executed by the first terminal device. The paging method includes: receiving a third paging message, the third paging message including multiple bit partitions; each bit partition of the multiple bit partitions is used to carry a first type of terminal device identifier; demodulating one or more bit partitions of the multiple bit partitions to obtain the first type of terminal device identifier carried by the one or more bit partitions.

[0029] In the embodiment of the present application, each bit partition in the third paging message carries a first type of terminal device identifier. When the terminal device demodulates the third paging message, it only needs to demodulate the first type of terminal device identifier carried by one or more bit partitions in the multiple bit partitions. The terminal device demodulates fewer bits during the demodulation process, and the power consumption required for the demodulation of the terminal device is also less, thereby reducing the power consumption of the terminal device during the paging process.

[0030] In combination with the above-mentioned second aspect, in a possible implementation method, it also includes: receiving third indication information, the third indication information is used to indicate the bit partition to be demodulated; demodulating one or more bit partitions of multiple bit partitions, and obtaining the first type of terminal device identifier carried by one or more bit partitions, including: demodulating the bit partition to be demodulated indicated by the third indication information, and determining the first type of terminal device identifier carried by the bit partition to be demodulated.

[0031] Based on this, the terminal device only demodulates the bit partition indicated by the third indication information, which can further reduce the number of bits demodulated by the terminal device during the demodulation process, thereby further reducing the power consumption of the terminal device during the paging process.

[0032] In combination with the above second aspect, in a possible implementation manner, the first type of terminal device identifier includes an identifier of a terminal device or an identifier of a terminal device group.

[0033] Based on this, the paging message can carry the identifier of the terminal device, so that the paging message directly pages a specific terminal device, or the paging message can carry the identifier of the terminal device group, so that the paging message can page the terminal devices in the entire terminal device group.

[0034] In combination with the above-mentioned second aspect, in a possible implementation method, the method is applied to a first terminal device; the first type of terminal device identifier includes the identifier of the first terminal device; the bit partition to be demodulated is the first bit partition to which the identifier of the first terminal device belongs in the third paging message; or, the first type of terminal device identifier includes the identifier of the terminal device group to which the first terminal device belongs; the bit partition to be demodulated is the first bit partition to which the identifier of the terminal device group to which the first terminal device belongs in the third paging message.

[0035] Based on this, the third paging message may page the first terminal device through the identifier of the terminal device, or may page the first terminal device through the identifier of the terminal device group.

[0036] In combination with the above-mentioned second aspect, in a possible implementation method, one or more bit partitions of multiple bit partitions are demodulated to obtain a first type of terminal device identifier carried by one or more bit partitions, including: based on a second preset rule, sequentially demodulating multiple bit partitions in the third paging message until the first bit partition including the identifier of the first terminal device or the identifier of the terminal device group to which the first terminal device belongs is demodulated, and then obtaining the identifier of the first terminal device or the identifier of the terminal device group to which the first terminal device belongs from the first bit partition.

[0037] Based on this, the terminal device can demodulate the bit partition in the third paging message based on preconfigured preset rules until the identifier of the first terminal device or the identifier of the terminal device group to which the first terminal device belongs is demodulated, and then stop demodulating to determine that the terminal device is the terminal device paged by the paging message.

[0038] In addition, if the terminal device fails to demodulate the identifier of the first terminal device or the identifier of the terminal device group to which the first terminal device belongs after demodulating multiple bit partitions of the third paging message, it is determined that the terminal device is not the terminal device paged by the paging message.

[0039] In combination with the above-mentioned second aspect, in a possible implementation method, the second preset rule includes at least one of the following: demodulating in sequence from large to small according to the bit partition index value, demodulating in sequence from small to large according to the bit partition index value, and demodulating in sequence starting from the specified bit position.

[0040] Based on this, the terminal device can determine the demodulation order of the demodulation bit partitions based on different rules, thereby improving the applicable scenarios of the terminal device demodulating the bit partitions of the third paging message.

[0041] In combination with the above-mentioned second aspect, in a possible implementation, the method also includes: receiving fourth indication information, the fourth indication information is used to indicate the type of paging message; the type of paging message includes: a third paging message or a fourth paging message; the fourth paging message is used to carry the second type of terminal device identifier.

[0042] Based on this, the access network device indicates the type of paging message to the terminal device. After determining the type of paging message, the terminal device can demodulate the paging message in a manner corresponding to that type, thereby avoiding the terminal device demodulating the paging message in an incorrect manner after receiving the paging message, resulting in unsuccessful demodulation.

[0043] In combination with the above-mentioned second aspect, in a possible implementation method, the third paging message also includes an identifier of an access and mobility management network element; the identifier of the access and mobility management network element carries a fourth bit sequence of the third paging message; the method also includes: when the access network device type is a first type of access network device, demodulating the fourth bit sequence of the third paging message to obtain the identifier of the access and mobility management network element included in the third paging message; when the access network device type is a second type of access network device, not demodulating the fourth bit sequence of the third paging message.

[0044] Based on this, the first paging message may also carry the identifier of the access and mobility management network element. The terminal device may choose whether to demodulate the identifier of the access and mobility management network element in the third paging message according to the access network type. When the terminal device demodulates the identifier of the access and mobility management network element in the third paging message, the terminal device may demodulate the terminal device identifier more accurately. When the terminal device does not demodulate the identifier of the access and mobility management network element in the third paging message, the number of bits used by the terminal device to demodulate the paging message may be reduced, further reducing the power consumption of the terminal device during the paging process.

[0045] In combination with the above second aspect, in a possible implementation manner, the first type of access network device is a shared access network device, and the second type of access network device is a non-shared access network device.

[0046] In a third aspect, a paging method is provided, which can be executed by an access network device, or by a component of the access network device, such as a processor, chip, or chip system of the access network device, or by a logic module or software that can implement all or part of the access network device. The following is an explanation of the method being executed by an access network device as an example. The paging method includes: sending a paging message; wherein the paging message is at least one of a first paging message, a second paging message, and a third paging message; the first paging message includes a first bit sequence in the second paging message, and the first bit sequence is used to carry a first type of terminal device identifier; the second paging message includes a first bit sequence and a second bit sequence; the first bit sequence and the second bit sequence are used to jointly carry a second type of terminal device identifier; the third paging message includes multiple bit partitions; each bit partition in the multiple bit partitions is used to carry a first type of terminal device identifier.

[0047] In the embodiment of the present application, the access network device has multiple paging messages for paging the terminal device, including a first paging message, a second paging message, and a third paging message. The access network device can flexibly select the paging message to page the terminal device. For example, the access network device can select the first paging message or the third paging message that carries the first type of terminal device identifier to page the terminal device, so as to reduce the number of bits required for demodulation when the terminal device demodulates the paging message. Alternatively, the access network device can also choose to page the terminal device through the second paging message, so that the terminal device can intercept the first paging message from the second paging message for demodulation after receiving the paging message.

[0048] In combination with the third aspect above, in a possible implementation manner, the method further includes: receiving a paging message from a core network device.

[0049] Based on this, the access network device directly forwards the paging message sent by the core network device to the terminal device, which can reduce the load of the access network device when processing the paging message.

[0050] In combination with the third aspect above, in a possible implementation, when the paging message is a first paging message, the method further includes: receiving a second paging message from a core network device; and intercepting a first bit sequence from the second paging message to obtain the first paging message.

[0051] Based on this, the first paging message with fewer bits transmitted between the access network device and the terminal device can reduce the transmission resources occupied by the paging message between the base station and the UE, and the terminal device only needs to receive and demodulate the first paging message, which can further reduce the power consumption of the terminal device to obtain the first paging message.

[0053] Based on this, the access network device can flexibly choose to send the first paging message or the second paging message based on the actual network scenario, making the paging method of the access network device more flexible.

[0055] In combination with the third aspect above, in a possible implementation, when the paging message is a second paging message, the method further includes: receiving a first paging message and a second paging message from a core network device; and selecting the second paging message from the first paging message and the second paging message.

[0056] Based on this, the access network device can flexibly choose to send the first paging message or the second paging message based on the actual network scenario, making the paging method of the access network device more flexible.

[0057] In combination with the above-mentioned third aspect, in a possible implementation method, when the paging message is a second paging message, the method also includes: sending first indication information, the first indication information is used to indicate at least one of the following: the position and quantity of the first bit sequence in the second paging message, and determining a first preset rule for the first bit sequence.

[0058] In combination with the above-mentioned third aspect, in a possible implementation method, the first preset rule includes at least one of the following: calculating the position and quantity of the first bit sequence in the second paging message according to a preset calculation method, and querying the position and quantity of the first bit sequence in the second paging message according to a preset record table; wherein the preset record table is used to record the position and quantity of the first bit sequence in the second paging message.

The device may be installed in the access network device or used in combination with the access network device.

[0112] To facilitate understanding of the technical solutions provided by the embodiments of the present application, a brief introduction to the related technologies of the present application is first given. The brief introduction is as follows:

[0113] 1. Discontinuous reception (DRX) mode

[0114] DRX mode is a mode of receiving signals adopted by terminal devices to reduce power consumption. The terminal device can decide whether to adopt DRX mode to receive signals according to the configuration of the access network device. When the terminal device adopts DRX mode to receive signals, the terminal device turns on the receiver to receive downlink data and signaling in a specific time period, and turns off the receiver and stops receiving downlink data and signaling in other time periods. After turning off the receiver, the terminal device does not need to continuously monitor the physical downlink control channel (PDCCH), thereby reducing the power consumption of the terminal device. DRX mode can be applied to the radio resource control (RRC) connection state, the RRC inactive state, and the RRC idle state. In addition, the DRX mode can also be extended to the extended discontinuous reception (eDRX) mode. The cycle of the eDRX mode will be longer, the sleep time of the terminal device will be longer, and the power consumption will be lower. However, the long cycle of the eDRX mode will cause the terminal device to receive new data and signaling for a longer period. Therefore, the eDRX mode is usually suitable for business scenarios with low latency requirements.

[0115] 2. Paging message

[0116] In one implementation of the DRX mode, the network side wakes up the terminal device through a paging message. The paging message is used to trigger the terminal device to establish an RRC connection, or to notify the terminal device of system information update, etc. The content of the paging message is usually sent to the terminal device through the physical downlink shared channel (PDSCH), and the PDSCH is usually scheduled by the PDCCH scrambled by the paging radio network temporary identifier (P-RNTI).

[0117] The process of a terminal device obtaining a paging message is as follows: a terminal device in an idle or inactive state is periodically awakened, and after the terminal device is awakened, the PDCCH encrypted by the P-RNTI is monitored through a paging opportunity (Paging Occasion, PO), and the downlink control information (downlink control information, DCI) in the PDCCH is parsed to determine the location (e.g., time-frequency location) information of the PDSCH. The terminal device receives the PDSCH according to the location information of the PDSCH, and obtains the paging message in the PDSCH. Further, the terminal device determines whether the paging message includes its own terminal device identity. If so, the terminal device performs corresponding operations (e.g., triggering the RRC setup process of the terminal device; triggering the RRC resume of the terminal device; notifying the terminal device to update the system message or receive the ETWS / CMAS notification).

[0118] A terminal device in an RRC connected state can determine whether the current system information has changed by decoding a paging message. When the terminal device detects a change in the system information, it obtains updated system information for update. In addition to determining whether the system information has changed, a terminal device in an RRC idle state can also determine whether the terminal device is called. If the terminal device is called, a random access process is triggered. In addition, the terminal device can also receive earthquake and tsunami warning system (ETWS) (corresponding to system information block (SIB) 6 and SIB7) and commercial mobile alert service (CMAS) information through paging messages.

[0119] The paging process in the 5G network includes the paging process triggered by the core network and the paging process triggered by the access network.

[0120] First, the paging process triggered by the core network is introduced: Figure 1 The present invention provides a flow chart of a paging process triggered by a core network when the access network device is a CU-DU architecture. Figure 1 As shown, the paging process triggered by the core network includes the following steps S101-S104.

[0121] S101. A core network device sends a paging message to a gNB-central unit (gNB-CU). Correspondingly, the gNB-CU receives the paging message from the core network device.

[0122] As an example, the core network device sends a paging message to the gNB-CU via the NG interface, where the NG interface is the interface between the base station and the core network.

[0123] In another example, the core network device in this step is an access and mobility management function (AMF).

[0124] In one possible implementation, the paging message sent by the core network device to the gNB-CU includes paging messages of terminal devices in one or more tracking areas. The terminal devices are distinguished by the shortened form of the 5G temporary mobile subscription identifier (5GS-temporary mobile subscription identifier, 5G-S-TMSI). For a detailed introduction to 5G-S-TMSI, please refer to the following text and will not be repeated here.

[0125] S102. The gNB-CU forwards the paging message to the gNB-distributed unit (gNB-DU). Correspondingly, the gNB-DU receives the paging message from the gNB-CU.

[0126] As an example, the gNB-CU forwards the paging message to the gNB-DU via the F1 interface. The F1 interface is the interface between the gNB-CU and the gNB-DU.

[0127] S103. The gNB-DU sends a paging message to the terminal device. Correspondingly, the terminal device receives the paging message from the gNB-DU.

[0128] In a possible implementation, the gNB-DU sends a paging message by broadcasting. After receiving the paging message, the terminal device demodulates the paging message to determine whether the terminal device is the terminal device paged by the paging message. In the case that the terminal device is the terminal device paged by the paging message, the terminal device performs relevant operations. For example, the terminal device performs the step of sending an RRC establishment request message to the gNB-CU in S104 below.

[0129] In one example, during the attach or tracking area updating (TAU) process, the terminal device negotiates the paging cycle of the terminal device with the core network device (such as AMF). When the base station forwards the paging message to the terminal device, it sends the paging message based on the paging cycle pre-negotiated between the terminal device and the core network device. The terminal device monitors the paging message sent by the base station in the paging cycle, and demodulates the received paging message after receiving the paging message.

[0130] Among them, the process of pre-negotiating the paging cycle between the terminal device and the core network device includes: the terminal device carries a paging cycle in the registration request message. After receiving the registration request message, the core network device indicates a paging cycle to the terminal device in the registration acceptance message. The paging cycle indicated by the core network device to the terminal device can be the same as the paging cycle requested by the terminal device, or it can be different from the paging cycle requested by the terminal device, and the embodiment of the present application does not make specific limitations on this.

[0131] S104. The terminal device sends an RRC establishment request message to the gNB-DU. Correspondingly, the gNB-DU receives the RRC establishment request message from the terminal device.

[0132] In one example, the above RRC establishment request message is: RRCSetupRequest.

[0133] It should be noted that when the terminal device determines that the terminal device is the terminal device paged by the paging message, the terminal device can also perform other actions, such as triggering the terminal device RRC resume; notifying the terminal device to update the system message or receive the ETWS / CMAS notification, which is not limited in this application.

[0134] Secondly, the paging process triggered by the access network device is introduced: in the paging process triggered by the access network device, after the access network device generates a paging message, it sends a paging message to the terminal device. After receiving the paging message, the terminal device demodulates the paging message to determine whether the terminal device is paged. In the case where the terminal device is paged, the terminal device performs related operations, which can be specifically referred to S103 and S104 above, and will not be repeated here. It should be pointed out that the access network device can send a paging message to the terminal device through RRC signaling configuration, and the paging message includes one or more terminal device identifiers, and the terminal device identifier can be 5G-S-TMSI (or NG-5G-S-TMSI).

[0135] The paging process triggered by the core network and the paging process triggered by the access network are described above.

[0136] The paging time in the paging cycle (that is, the time when the terminal device detects the paging message) can be identified by the paging frame (PF) and the paging occasion (PO). PF is used to indicate the system frame number of the paging frame for sending the paging message, and PO is used to indicate the subframe occasion for sending the paging message. A PF is a radio frame. A PF usually includes one or more POs (or the starting point of a PO). The terminal device only monitors the PO corresponding to the terminal device in a paging cycle. PO is a collection of one or more PDCCH monitoring occasions. A PO includes one or more time slots (for example, subframes or orthogonal frequency-division multiplexing (OFDM) symbols). The access network device sends PDCCH in the time slot included in the PO.

[0137] In one example, the calculation formula of the system frame number of PF satisfies the following formula 1:

[0138] (SFN+PF_offset)mod T=(T div M)*(UE_ID mod N) Formula 1

[0139] Among them, SFN is the system frame number, PF_offset represents the offset for determining the system frame number, T identifies the DRX cycle or paging cycle of the terminal device, N represents the total number of paging frames in the DRX cycle or paging cycle, and UE_ID is the identifier of the terminal device.

[0140] The calculation formula of the PO index i_s satisfies the following formula 2:

[0141] i_s=floor(UE_ID / M)mod Ns Formula 2

[0142] Where Ns represents the number of POs in each PF.

[0143] 3. 5G-S-TMSI

[0144] 5G-S-TMSI is usually used in paging messages to uniquely identify terminal devices. For example, the identity of the terminal device paged by the paging message is carried in the 5G-S-TMSI of the information element (IE) PagingUE-Identity in the RRC signaling. The terminal device identity carried by the 5G-S-TMSI is determined by the core network and the identity of each terminal device is unique within a tracking area.

[0145] 5G-S-TMSI contains a total of 48 bits, of which 16 bits are used to identify the AMF accessed by the terminal device, and the remaining 32 bits are 5G-TMSI. 5G-TMSI is used to identify the terminal device accessed in the AMF. Among the 16 bits used to identify the AMF, 10 bits identify the AMF set ID and 6 bits identify the AMF Pointer. In the 32-bit 5G-TMSI used to represent the terminal device, each terminal device accessing the same AMF has a unique 5G temporary mobile subscription identifier (5G temporary mobile subscription identifier, 5G-TMSI). That is, among the terminal devices accessing the same AMF, one 5G-TMSI is used to uniquely identify one terminal device. In 5G-S-TMSI, by setting the value of 48 bits, 5G-S-TMSI can distinguish between 2 48 A terminal device.

[0146] It should be noted that the 5G-S-TMSI field can identify a terminal device (UE) or a terminal device group (UE Group). When the S-TMSI field in the paging message identifies a terminal device, the paging message can wake up a terminal device; when the S-TMSI field in the paging message identifies a terminal device group, the paging message can wake up a terminal device in a terminal device group.

[0147] In one example, the 5G-S-TMSI specifically includes the following contents:

[0148]

[0149] 4. Low power wake up receiver (LP-WUR) and low power wake up signal (LP-WUS)

[0150] LP-WUR is a receiver designed to reduce power consumption. The module design of LP-WUR is simpler. For example, unlike the RF and baseband parts of the NR receiver, LP-WUR usually omits the baseband part and only retains the RF part; or, on the premise of omitting the baseband part and retaining the RF part, a computing module is added to perform basic operations (such as addition, subtraction, multiplication and division). In this way, the baseband part with higher power consumption is omitted in LP-WUR, which can greatly reduce the power consumption of LP-WUR.

[0151] The low power wake up signal (LP-WUS) is a signal designed for the LP-WUR. The LP-WUR does not need to perform baseband processing and complex demodulation process (or does not need to perform demodulation) when receiving the LP-WUS.

[0152] Currently, the waveform design of LP-WUS includes the following methods:

[0153] Mode 1, on-off keying (OOK), refers to the use of different bit values ​​to indicate whether a signal is sent. For example, a bit value of 0 indicates that the access network device does not send any signal to the terminal device, and the terminal device does not need to detect the signal from the access network device at the corresponding time domain position. A bit value of 1 indicates that the access network device sends a signal to the terminal device. The terminal device demodulates according to the modulation method of the pre-configured waveform to determine whether the base station is scheduling the terminal device.

[0154] Mode 2, frequency shift keying, refers to the use of different bit values ​​to represent the signal sent in different frequency domains. Taking the signal bandwidth as 12RB, the frequency domain range is divided into 4 parts, namely part #1, part #2, part #3, and part #4 as an example, the bit value of 00 indicates that the LP-WUS signal is sent in part #1, and the terminal device only needs to perform signal detection in part #1; the bit value of 01 indicates that the LP-WUS signal is sent in part #2, and the terminal device only needs to perform signal detection in part #2; the bit value of 10 indicates that the LP-WUS signal is sent in part #3, and the terminal device only needs to perform signal detection in part #3; the bit value of 11 indicates that the LP-WUS signal is sent in part #4, and the terminal device only needs to perform signal detection in part #4.

[0155] Method 3, based on OFDM, refers to carrying different bit values ​​through different sequences. In some implementations, different sequences represent different bit streams. For example, a paging message contains 10 bits, and different bit values ​​of the 10 bits of the paging message represent different terminal device identifiers. In this case, a 10-bit paging message corresponds to 2 10 different bit sequences, 2 10 Different bit sequences can distinguish 2 10The identifier of a terminal device. In some other implementations, different sequences are used to carry different bit values ​​in a symbol. For example, a symbol includes two bits, and when the two bits in the symbol take different values, four bit sequences may correspond. For example, four Zadoff-Chu (zc) sequences are used, and these four zc sequences use the same root but have different cyclic shifts. For example, the roots of the four sequences are all 1, the cyclic shift of sequence #1 is 5, and the bit value represented is 00; the cyclic shift of sequence #2 is 12, and the bit value represented is 01; the cyclic shift of sequence #3 is 24, and the bit value represented is 10; the cyclic shift of sequence #4 is 35, and the bit value represented is 11.

[0156] 5. Network Sharing

[0157] Network sharing refers to the sharing of resources of a single network between multiple operators. Each sharing operator allocates shared resources through a pre-agreed plan. Network sharing can reduce the network costs of operators, effectively utilize network capacity, and improve network resource utilization. The current shared network includes radio access networks, and shared resources include radio resources.

[0158] The network architecture of 5G network sharing includes 5G MOCN, in which operators only share the access network. Figure 2 A schematic diagram of the system architecture of 5G MOCN provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the core networks of multiple operators (including operator A, operator B, and operator C) access a shared access network (such as a shared NG-RAN), and the core network and the access network can communicate through the N2 and / or N3 interface.

[0159] In the 5G MOCN network, operators can use multiple public land mobile network (PLMN) IDs or a combination of PLMN ID and network identifier (NID). The network management system can configure the same cell under the 5G standalone (SA) shared base station as multiple PLMN-IdentityInfo objects. Each PLMN-IdentityInfo object corresponds to an operator, and the PLMN-IdentityInfo object includes the corresponding operator's PLMN ID, tracking area code (TAC), gNodeB ID, Cell ID and other fields.

[0160] It should be noted that multiple PLMN-IdentityInfo objects in the same cell can be configured as completely identical PLMN-IdentityInfo objects or completely different PLMN-IdentityInfo objects. Configuring multiple PLMN-IdentityInfo objects in the same cell as completely different PLMN-IdentityInfo objects means that a base station can be configured with different logical gNB-IDs and Cell-IDs for use by different operators. The parameters under each set of logical gNB-IDs and Cell-IDs are independent and do not affect each other. This can avoid the problem of gNB-ID and Cell-ID code conflicts between operators and allow operators to independently optimize parameter configuration according to their own needs.

[0161] The above is a brief introduction to the related technologies of this application.

[0162] Currently, the power consumption of terminal devices greatly affects the user experience. For example, in scenarios where the terminal device cannot use continuous energy, the terminal device needs to rely on batteries (such as small rechargeable batteries and single-coin batteries) to provide energy. Due to the size of the terminal device, the battery capacity of the terminal device is usually limited. After the battery of the terminal device is exhausted, the battery of the terminal device needs to be charged or replaced before the terminal device can continue to be used normally.

[0163] In order to reduce the power consumption of terminal devices, it is currently possible to reasonably set the wake-up cycle of the terminal devices to reduce the wake-up time of the terminal devices without affecting the normal operation of the terminal devices, thereby reducing the power consumption of the terminal devices (for details, please refer to the introduction of the above DRX mode and paging message).

[0164] However, during the paging process, the low-power terminal device will also generate high power consumption when demodulating the paging message, which affects the working time of the low-power terminal device. Therefore, how to reduce the power consumption of the terminal device during the paging process is a technical problem that needs to be solved at present.

[0165] In order to solve the above technical problems, an embodiment of the present application provides a paging method. During the paging process, the terminal device demodulates the first bit sequence from the first paging message to obtain the first type of terminal device identification. Since the first paging message and the second paging message carry different types of terminal device identifications respectively, and the first paging message includes a partial bit sequence of the second paging message, the terminal device can obtain the terminal device identification of the paging message by demodulating fewer bits. The terminal device demodulates fewer bits during the paging process, and the power consumption required for the demodulation of the terminal device is also less, thereby reducing the power consumption of the terminal device during the paging process.

[0166] The paging method provided in the embodiment of the present application can be applied to Figure 3 In the communication system 30 shown. Figure 3 As shown, the paging system includes: an access network device 301 and at least one terminal device 302.

[0167] Among them, the access network device 301 is used to send (such as broadcasting) a paging message to the terminal device 302. After receiving the paging message from the access network device, the terminal device 302 demodulates the bits in the paging message to determine the identifier of the terminal device paged by the paging message. In the case where it is determined that the terminal device is a terminal device paged by the paging message, the terminal device performs a corresponding action based on the content of the paging message (refer to the description in the above-mentioned related technology, which will not be repeated here). In the case where it is determined that the terminal device is not a terminal device paged by the paging message, the terminal device enters a dormant state.

[0168] Optional, such as Figure 3 The communication system shown may further include a core network device 303. The paging message forwarding process may be: the core network device 303 generates a paging message and sends the paging message to the access network device 301; after receiving the paging message, the access network device 301 sends the paging message to the terminal device 302. Alternatively, the core network device 301 directly generates a paging message and sends the paging message to the terminal device 302.

[0169] The terminal device 302 is connected to the access network device 301 by wireless means, and the access network device 301 is connected to the core network device 303 by wireless or wired means. The core network device 303 and the access network device 301 can be independent and different physical devices, or the functions of the core network device 303 and the logical functions of the access network device 301 can be integrated on the same physical device, or part of the functions of the core network device 303 and part of the functions of the access network device 301 can be integrated on one physical device. The terminal device 302 can be fixed or movable. Figure 3 This is just a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices. Figure 3 In addition, the embodiment of the present application does not limit the number of core network devices 303, access network devices 301 and terminal devices 302 included in the mobile communication system.

[0170] Optionally, in the embodiment of the present application, the access network device 301 and the terminal device 302 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on airplanes, balloons and satellites in the air. The embodiment of the present application does not limit the application scenarios of the access network device 301 and the terminal device 302.

[0171] The embodiments of the present application may be applicable to downlink signal transmission, uplink signal transmission, and device-to-device (D2D) signal transmission. For downlink signal transmission, the sending device is the access network device 301, and the corresponding receiving device is the terminal device 302. For uplink signal transmission, the sending device is the terminal device 302, and the corresponding receiving device is the access network device 301. For D2D signal transmission, the sending device is the terminal device 302, and the corresponding receiving device is also the terminal device 302. The embodiments of the present application do not limit the transmission direction of the signal.

[0172] Optionally, in an embodiment of the present application, the access network device 301 and the terminal device 302 and the terminal device 302 and the terminal device 302 can communicate through a licensed spectrum, or can communicate through an unlicensed spectrum, or can communicate through both a licensed spectrum and an unlicensed spectrum. In addition, the access network device 301 and the terminal device 302 and the terminal device 302 and the terminal device 302 can communicate through a spectrum below 6G, or can communicate through a spectrum above 6G, or can communicate through both a spectrum below 6G and a spectrum above 6G. The embodiment of the present application does not limit the spectrum resources used between the access network device 301 and the terminal device 302.

[0173] Combination Figure 3 The communication system shown in Figure 4 As shown, a paging method provided in an embodiment of the present application is described by taking the interaction between a first terminal device and an access network device as an example. Of course, the subject that executes the action of the first terminal device in the method may also be a device / module in the first terminal device, such as a chip, a processor, a processing unit, etc. in the first terminal device; the subject that executes the action of the access network device in the method may also be a device / module in the access network device, such as a chip, a processor, a processing unit, etc. in the access network device, and the embodiment of the present application does not make specific limitations on this. The processing performed by a single execution subject (for example, a first terminal device or an access network device) in an embodiment of the present application may also be divided into executions by multiple execution subjects, and these execution subjects may be logically and / or physically separated. For example, the processing performed by the access network device may be divided into executions by at least one of CU, DU and RU. Exemplarily, as Figure 4 As shown, the method comprises the following steps:

[0174] S401: The access network device sends a paging message to the first terminal device. Correspondingly, the first terminal device receives the paging message from the access network device.

[0175] Among them, the paging message is at least one of a first paging message, a second paging message, and a third paging message; the first paging message includes the first bit sequence in the second paging message, and the first bit sequence is used to carry the first type of terminal device identification; the second paging message includes the first bit sequence and the second bit sequence; the first bit sequence and the second bit sequence are used to jointly carry the second type of terminal device identification; the third paging message includes multiple bit partitions; each bit partition in the multiple bit partitions is used to carry the first type of terminal device identification.

[0176] In a possible implementation, the first type terminal device identifier and the second type terminal device identifier are used to identify different types of terminal devices. For example, the first type terminal device identifier is used to identify a low-power terminal device, such as a low power wake up receiver (LP-WUR), and the second type terminal device identifier is used to identify a non-low-power terminal device.

[0177] In an embodiment of the present application, the access network device can select the type of paging message to be sent according to actual needs. For example, when paging a low-power terminal device, select the first paging message or the third paging message to page the low-power terminal device. When paging a non-low-power terminal device, select the second paging message to page the non-low-power terminal device. In this way, the paging message for paging the low-power terminal device can include a smaller number of bits, so that the terminal device demodulates fewer bits when demodulating the paging message, and the power consumption required for the terminal device to demodulate is also less. It should be pointed out that when the access network device paging the low-power terminal device, it can also select the second paging message to page the low-power terminal device, but the terminal device identifier of the low-power terminal device is only carried on part of the bits of the second paging message (such as the first bit sequence). After the low-power terminal device receives the second paging message, it only demodulates the bit of the terminal device identifier that carries the low-power terminal device, so that the number of bits demodulated by the terminal device when demodulating the paging message will also be less, and the power consumption required for the terminal device to demodulate is also less.

[0178] It should be noted that, in the embodiment of the present application, the bit sequence (including but not limited to the first bit sequence, the second bit sequence, the third bit sequence and the fourth bit sequence) may include multiple continuous bits, and may also include multiple non-continuous bits. For example, the first bit sequence includes the first 12 continuous bits in the second paging message, and the second bit sequence includes the last 36 continuous bits in the second paging message. For another example, the first bit sequence includes the last 12 continuous bits in the second paging message, and the second bit sequence includes the first 36 continuous bits in the second paging message. For another example, the first bit sequence includes the 12th to 24th continuous bits in the second paging message, and the second bit sequence includes the 1st to 11th continuous bits and the 25th to 48th continuous bits in the second paging message. For another example, the first bit sequence includes the 1st, 3rd, 5th, 7th, 9th, 11th, 13th, 15th, 17th, 19th, 21st, and 23rd bits in the second paging message, and the second bit sequence includes the bits in the second paging message other than the first bit sequence. In addition, the bits included in the first bit sequence and the second bit sequence may also be other continuous or non-continuous bits, which is not limited in this application.

[0179] S402: The first terminal device demodulates the paging message and determines the first type of terminal device identifier carried by the paging message.

[0180] In a possible implementation, when the first terminal device demodulates the paging message, it may demodulate after receiving all the bits of the paging message. Alternatively, the first terminal device may demodulate while receiving, for example, demodulating the currently received bit after receiving one bit, receiving the next bit for demodulation after correctly demodulating the currently received bit, and stopping demodulating the remaining bits in the paging message when the current bit is demodulated incorrectly.

[0181] As an example, the second paging message in the embodiment of the present application may be a 48-bit paging message, and the first paging message is a paging message with less than 48 bits (for example, a 12-bit paging message intercepted from the second paging message). The third paging message is a 48-bit paging message, and the number of paging messages in each bit partition is less than 48 bits.

[0182] Optionally, the first terminal device is a low-power terminal device, so the first terminal device only needs to demodulate the first bit sequence, or demodulate one or more bit partitions to obtain the first type of terminal device identification to complete the demodulation process of the paging message. Compared with the prior art in which the terminal device needs to demodulate a 48-bit paging message before obtaining the identification of the paging terminal device, in the embodiment of the present application, the first terminal device does not need to demodulate all the bits of the paging message, thereby reducing the power consumption of the terminal device in demodulating the paging message.

[0183] In the embodiment of the present application, the access network device has multiple paging messages for paging the terminal device, including a first paging message, a second paging message, and a third paging message. The access network device can flexibly select the paging message to page the terminal device. For example, the access network device can select the first paging message or the third paging message that carries the first type of terminal device identifier to page the terminal device, so as to reduce the number of bits required for demodulation when the terminal device demodulates the paging message. Alternatively, the access network device can also choose to page the terminal device through the second paging message, so that the terminal device can intercept the first paging message from the second paging message for demodulation after receiving the paging message.

[0184] It should be noted that the scenarios of the paging message sent by the access network device include: scenario 1, the paging message is the first paging message; scenario 2, the paging message is the second paging message; scenario 3, the paging message is the third paging message. For different scenarios, the process of demodulating the paging message by the first terminal device is different. The process of demodulating the paging message by the first terminal device in each scenario is described in detail below:

[0185] Scenario 1: The paging message is the first paging message

[0186] In scenario 1, combined with Figure 4 ,like Figure 5 As shown, the above S402 can be specifically implemented by the following S501:

[0187] S501. A first terminal device demodulates a first bit sequence in a first paging message to obtain a first type of terminal device identifier.

[0188] In a possible implementation, the first paging message includes only the first bit sequence, or the first paging message may also include other bit sequences in addition to the first bit sequence, such as a third bit sequence (or fourth bit sequence) carrying an identifier of an access and mobility management network element.

[0189] In a possible implementation manner, the first paging message is a paging message obtained by the access network device and / or the core network device after intercepting the first bit sequence from the second paging message.

[0190] It should be pointed out that intercepting the first bit sequence from the second paging message to obtain the first paging message may refer to deleting the bits other than the first bit sequence from the second paging message, and only intercepting and retaining the first bit sequence. It may also refer to identifying (or indicating) the first bit sequence to be intercepted in the second paging message, and the terminal device determines the first bit sequence to be intercepted based on the identification or indication, and demodulates the first bit sequence. Alternatively, interception can be understood as enabling the terminal device to determine the first bit sequence to be intercepted in the second paging message, and the specific interception method is not limited in this application.

[0191] In another possible implementation manner, the first paging message is a paging message selected by the access network device from a first paging message and a second paging message sent by the core network device.

[0192] In the embodiment of the present application, the first paging message and the second paging message respectively carry different types of terminal device identifiers, and the first paging message includes a partial bit sequence of the second paging message. During the paging process, the terminal device demodulates the first bit sequence from the first paging message to obtain the first type of terminal device identifier, so that the terminal device can obtain the terminal device identifier of the paging message while demodulating fewer bits. Therefore, the terminal device demodulates fewer bits during the paging process, and the power consumption required for the demodulation of the terminal device is also less, thereby reducing the power consumption of the terminal device during the paging process.

[0193] Scenario 2: The paging message is the second paging message

[0194] In scenario 2, combined with Figure 4 ,like Figure 6 As shown, the above S402 can be specifically implemented through the following S601 and S602.

[0195] S601. A first terminal device intercepts a first bit sequence from a second paging message to obtain a first paging message.

[0196] In a possible implementation, the access network device sends a second paging message to the first terminal device. After receiving the second paging message from the access network device, the first terminal device determines a first bit sequence in the second paging message and extracts the first bit sequence from the second paging message to obtain the first paging message.

[0197] S602: The first terminal device demodulates the first bit sequence in the first paging message to obtain a first type of terminal device identifier.

[0198] Based on this, after receiving the second paging message, the first terminal device can intercept the first paging message from the second paging message for demodulation, thereby reducing the number of bits required for demodulation when the first terminal device demodulates the paging message.

[0199] The specific implementation process of S602 may refer to the above S501 and will not be described in detail here.

[0200] In a possible implementation, the first terminal device intercepting the first bit sequence from the second paging message in the above S601 includes the following two implementation situations: situation 1, the access network device instructs to intercept the first bit sequence; situation 2, the first terminal device intercepts the first bit sequence based on the first preset rule. The following describes situation 1 and situation 2 in detail.

[0201] Case 1: The access network device instructs to intercept the first bit sequence

[0202] Combination Figure 6 ,like Figure 7 As shown, in situation 1, the above S601 can be specifically implemented through the following S701 and S702.

[0203] S701: An access network device sends first indication information to a first terminal device. Correspondingly, the first terminal device receives the first indication information from the access network device.

[0204] The first indication information is used to indicate at least one of the following: the position and quantity of the first bit sequence in the second paging message, and a first preset rule for determining the first bit sequence.

[0205] S702. The first terminal device intercepts a first bit sequence from the second paging message based on the first indication information to obtain a first paging message.

[0206] In one possible implementation, the above-mentioned first indication information can be carried in any of the following signaling messages sent by the access network device to the first terminal device: radio resource control signaling message (such as RRC signaling message); media access control layer control element (media access control control element, MAC-CE) signaling message; downlink control information signaling message (such as DCI signaling message); system information block (such as SIB).

[0207] For example, when the first terminal device is in an RRC connected state, the first indication information can be carried in an RRC signaling message, or a MAC-CE signaling message, or a DCI signaling message. Optionally, when the first indication information has a small number of bits and needs to be transmitted quickly, the first indication information can be carried in a DCI signaling message. When the first indication information has a large number of bits and does not need to be updated for a long time, the first indication information can be carried in an RRC signaling message, and before receiving new first indication information, the first terminal device processes according to the content indicated by the first indication information.

[0208] When the first terminal device is in the RRC idle state or the activated state, the first indication information can be carried in the SIB. The SIB can carry the first indication information of multiple terminal devices to indicate the position and quantity of the first bit sequences corresponding to the multiple terminal devices. For example, when the access network device uses different paging messages to page the low-power terminal device and the non-low-power terminal device respectively, the access network device carries the first indication information in the SIB message to indicate the position and quantity of the first bit sequences corresponding to each low-power terminal device.

[0209] Case 2: The first terminal device intercepts the first bit sequence based on the first preset rule

[0210] like Figure 7 As shown, in situation 2, the above S601 can be specifically implemented through the following S703.

[0211] S703. The first terminal device intercepts a first bit sequence from the second paging message based on a first preset rule to obtain a first paging message.

[0212] In a possible implementation, the first preset rule in the above case 1 and the above case 2 includes: Rule 1, calculating the position and quantity of the first bit sequence in the second paging message according to a preset calculation method. Rule 2, querying the position and quantity of the first bit sequence in the second paging message according to a preset record table; wherein the preset record table is used to record the position and quantity of the first bit sequence in the second paging message.

[0213] Optionally, for the above rule 1, the first terminal device may calculate the position and quantity of the first bit sequence according to the calculation method defined in rule 1. Exemplarily, the index X of the first bit sequence satisfies formula 3:

[0214] X=NG-5G-S-TMSI div(s*2 k ) Formula 3

[0215] The index X of the first bit sequence is used to represent the bit position (such as the starting position and the ending position) of the first bit sequence, k represents the number of bits in the first bit sequence, and s represents the scaling factor. k If the first bit sequence is used to distinguish less than 2 terminal devices, the value of s can be 1. k If there are multiple terminal devices, the value of s can be set according to the network load or access network device scheduling. The value of s can be predefined or dynamically configured. In the case of dynamically configuring the value of s, the access network device can configure the value of s through RRC signaling messages, MAC-CE signaling messages, or DCI signaling messages.

[0216] For the above rule 2, the first terminal device can query the position of the first bit sequence according to the table predefined in rule 2. The table can be pre-configured in the first terminal device; it can also be pre-configured in the access network device, and the access network device indicates the table to the first terminal device through indication information (such as the first indication information). Exemplarily, the table is shown in the following Table 1:

[0217] Table 1

[0218] Scope of terminal equipment identification Position of the first bit sequence (bits) <![CDATA[A1-A j ]]> 16-26

[0219] Among them, A1-A j is the identifier of the jth terminal device, j is a positive integer, and Table 1 is used to represent A1-A j The position of the first bit sequence corresponding to the j terminal devices is from the 16th bit position to the 26th bit position.

[0220] It should be noted that in situation 2, the first terminal device and the access network device are configured with the same rules. For example, the first access network device and the second access network device are both pre-configured with rule 1, and the access network device determines the position and quantity of the first bit sequence based on rule 1, and then generates a second paging message. The first terminal device determines the position and quantity of the first bit sequence according to rule 1, and then intercepts the first bit sequence. In addition, multiple rules can also be pre-configured in the first terminal device, and the first terminal device selects a rule from the multiple rules to determine the position and quantity of the first bit sequence.

[0221] In situation 1, the first terminal device and the access network device may be configured with multiple rules, and the access network device indicates to the first terminal device the rule for determining the position and quantity of the first bit sequence. For example, both the first access network device and the second access network device are configured with rule 1 and rule 2, and the first access network device determines the position and quantity of the first bit sequence based on rule 1, and then generates a second paging message. The first access network device indicates rule 1 through the first indication information, and the first terminal device determines the position and quantity of the first bit sequence according to rule 1, and then intercepts the first bit sequence.

[0222] In a possible implementation, the first bit sequence includes N bits from high to low in the bit positions of the second paging message; N is a positive integer. Alternatively, the first bit sequence includes N bits from low to high in the bit positions of the second paging message. Alternatively, the first bit sequence includes bits at N preset positions of the second paging message.

[0223] After the core network device or the access network device generates the second paging message in the above order, the arrangement of the first bit sequence in the second paging message can be indicated to the first terminal device through the indication information. After receiving the second paging message, the first terminal device only needs to determine the position of the first bit sequence to be demodulated according to the arrangement, and demodulate the first bit sequence. Among them, the indication information for indicating the arrangement of the first bit sequence in the second paging message can be carried in one or more of the RRC signaling message, the MAC-CE signaling message, the DCI signaling message, and the SIB, and this application does not limit this.

[0224] It is understandable that in an embodiment of the present application, the number of bits of the first bit sequence can be determined based on at least one of the following: network load, wake-up signal modulation method, measurement accuracy, and network coverage requirements. For example, the current network load is 10 terminal devices. At this time, the 10 terminal devices can be distinguished by 4 bits in the first bit sequence. At this time, the number of bits of the first bit sequence is greater than or equal to 4. For another example, in a scenario with high network coverage requirements, the shorter the bit stream of the data packet, the lower the error rate. At this time, the number of bits in the paging message can be set to the minimum number of bits that can distinguish all terminal devices in the current network. This embodiment of the present application does not limit this.

[0225] Optionally, the number of bits of the first bit sequence may be: 10, 12, 16, 20, 26, 32. Alternatively, the number of bits of the first bit sequence may also be other values, which are not limited in the present application.

[0226] In one example, taking the value of N as 10, and the first bit sequence including 10 bits from high to low in the bit positions of the second paging message as an example, the arrangement diagram of the first bit sequence in the second paging message is as follows: Figure 8 shown.

[0227] It is understandable that the value of N can be determined based on the number of first type terminal devices in the network. The N bits in the first bit sequence should be able to distinguish all first type terminal devices in the network. The first type terminal device can report to the core network device whether it needs to demodulate the first paging message (or report whether it demodulates the first paging message or the second paging message). The core network device determines the value of N based on the number of terminal devices that need to demodulate the first paging message.

[0228] In a possible implementation, based on the above scenario 1 and the above scenario 2, before sending the paging message to the first terminal device, the access network device may also indicate the type of the paging message to the first terminal device, so that the first terminal device can demodulate the paging message using a corresponding demodulation method according to the type of the paging message. Figure 7 ,like Fig. 9 As shown, the method also includes:

[0229] S901: The access network device sends second indication information to the first terminal device. Correspondingly, the first terminal device receives the second indication information from the access network device.

[0230] The second indication information is used to indicate the type of the paging message; the type of the paging message includes: a first paging message or a second paging message.

[0231] After the first terminal device receives the second indication information, if it is determined that the type of the paging message indicated by the second indication information is the first paging message, the first terminal device directly demodulates the first bit sequence in the first paging message to determine the first type of terminal device identifier. If it is determined that the type of the paging message indicated by the second indication information is the second paging message, the first terminal device intercepts the first bit sequence from the second paging message to obtain the first paging message, and demodulates the first bit sequence in the first paging message to determine the first type of terminal device identifier; or, the first terminal device directly demodulates the complete second paging message to determine the second type of terminal device identifier carried by the second paging message.

[0232] In one possible implementation, the core network device and the access network device can determine the type of the generated paging message based on parameters such as network load, false alarm rate index, false detection rate index, coverage requirements, and power consumption requirements, and indicate the type of the paging message to the first access network device through the second indication information, so that the first terminal device can demodulate through the corresponding demodulation operation.

[0233] It should be noted that, when the core network device determines the type of paging message to be generated, the second indication information can be carried in the paging message sent by the core network device to the first terminal device. When the access network device determines the type of paging message to be generated, the second indication information can be carried in one or more of the RRC signaling message, MAC-CE signaling message, DCI signaling message, and SIB sent by the access network device to the first terminal device.

[0234] In a possible implementation, when the first terminal device needs to demodulate the first paging message, the first paging message is a paging message obtained by the access network device after intercepting the first bit sequence from the second paging message; or, the first paging message is a paging message obtained by the core network device after intercepting the first bit sequence from the second paging message; or, the first paging message is a paging message selected by the access network device from the first paging message and the second paging message sent by the core network device. Alternatively, the first paging message is obtained by intercepting the first bit sequence from the second paging message after the first terminal device receives the second paging message from the access network device.

[0235] In other words, the core network device generates a second paging message corresponding to the terminal device. When the terminal device is a first type of terminal device and the terminal device needs to be paged through the first paging message this time, the core network device intercepts the first paging message from the second paging message and sends the first paging message to the access network device. After receiving the first paging message, the access network device forwards the first paging message to the terminal device. After receiving the first paging message, the terminal device demodulates the first paging message. In this way, the core network device directly intercepts the first paging message from the second paging message, the number of bits of the paging message sent by the core network device to the access network device is smaller, and the network resources of the core network device and the access network device are better occupied, which can increase the network capacity between the core network device and the access network device.

[0236] Alternatively, the core network device generates a second paging message corresponding to the terminal device. When the terminal device is a first type of terminal device and the terminal device needs to be paged by the first paging message this time, the core network device intercepts the first paging message from the second paging message and sends the first paging message and the second paging message to the access network device. After receiving the first paging message and the second paging message, the access network device selects whether to send the first paging message or the second paging message to the terminal device, and sends the first paging message or the second paging message to the terminal device according to the selection result. If the first paging message is selected to be sent, the terminal device demodulates the first paging message after receiving the first paging message. If the second paging message is selected to be sent, the terminal device can directly demodulate the second paging message after receiving the second paging message, or can intercept the first bit sequence from the second paging message to obtain the first paging message and demodulate the first paging message. In this way, the core network device sends two sets of paging messages to the access network device, and the access network device selects one set of paging messages to send to the terminal device according to the actual network situation, thereby increasing the flexibility of the access network device in sending paging messages.

[0237] Alternatively, the core network device generates a second paging message corresponding to the terminal device, and sends the second paging message to the access network device. After receiving the second paging message, the access network device determines whether to send the first paging message or the second paging message to the terminal device. If it is determined to send the first paging message to the terminal device, the access network device intercepts the first bit sequence from the second paging message to obtain the first paging message and sends the first paging message to the terminal device. After receiving the first paging message, the terminal device demodulates the first paging message. If it is determined to send the second paging message to the terminal device, the access network device directly forwards the received second paging message to the terminal device. After receiving the second paging message, the terminal device can directly demodulate the second paging message, or intercept the first bit sequence from the second paging message to obtain the first paging message and demodulate the second paging message. In this way, the access network device can flexibly select the type of paging message sent to the terminal device. In the case of sending the first paging message to the terminal device, the access network device sends the paging message to the terminal device with fewer bits, occupies the access network device and the terminal device network resources better, and can increase the network capacity between the access network device and the terminal device. In the case of sending the second paging message to the terminal device, the terminal device can choose to demodulate the first paging message or the second paging message, which increases the flexibility of the terminal device in demodulating the paging message.

[0238] Scenario 3: The paging message is the third paging message.

[0239] In scenario 3, combined with Figure 4 ,like Fig.10 As shown, the above S402 can be specifically implemented by the following S1001:

[0240] S1001. A first terminal device demodulates one or more bit partitions of a plurality of bit partitions to obtain a first type of terminal device identifier carried by the one or more bit partitions.

[0241] Different bit partitions of the third paging message correspond to different terminal devices. When a terminal device needs to be paged, the bit partition corresponding to the terminal device of the third paging message carries the identifier of the terminal device. After receiving the third paging message, the terminal device can demodulate the identifier of the terminal device in its corresponding bit partition.

[0242] An example, such as Fig.11As shown, the third paging message includes 3 bit partitions, namely bit partition #1, bit partition #2 and bit partition #3. Among them, bit partition #1 corresponds to terminal devices #1-terminal devices #10, and the 10 terminal devices #1-terminal devices #10 are distinguished by setting the bits in bit partition #1 to different values; bit partition #2 corresponds to terminal devices #11-terminal devices #20, and the 10 terminal devices #11-terminal devices #20 are distinguished by setting the bits in bit partition #2 to different values; bit partition #3 corresponds to terminal devices #21-terminal devices #30, and the 10 terminal devices #21-terminal devices #30 are distinguished by setting the bits in bit partition #3 to different values.

[0243] In a possible implementation, the process of the first terminal device demodulating one or more bit partitions of the multiple bit partitions in S1001 includes the following two implementation situations: situation 3, the access network device indicates the partition to be demodulated to the first terminal device; situation 4, the first terminal device demodulates the third paging message based on the second preset rule. The following describes situation 3 and situation 4 in detail.

[0244] Case 3: The access network device indicates the partition to be demodulated to the first terminal device

[0245] Combination Fig.10 ,like Fig.12 As shown, in situation 3, the above S1001 can be specifically implemented through the following S1201 and S1202.

[0246] S1201: The access network device sends third indication information to the first terminal device. Correspondingly, the first terminal device receives the third indication information from the access network device.

[0247] The third indication information is used to indicate the bit partition to be demodulated.

[0248] S1202. The first terminal device demodulates the bit partition to be demodulated indicated by the third indication information, and determines the first type of terminal device identifier carried by the bit partition to be demodulated.

[0249] It should be pointed out that the signaling message carrying the third indication information is similar to the signaling message carrying the above-mentioned first indication information. Its specific description can refer to the description of the signaling message carrying the first indication information in Case 1 of the above-mentioned scenario 2, and will not be repeated here.

[0250] In a possible implementation, the third indication information may directly indicate the index of the partition to be demodulated, and the first terminal device determines the partition to be demodulated according to the index indicated by the third indication information. For example, the access network device determines that the terminal device to be paged is one of the terminal devices #21-terminal devices #30. At this time, the third indication information sent by the access network device to the first terminal device is used to indicate the index of bit partition #3.

[0251] Case 4: The first terminal device demodulates the third paging message based on the second preset rule.

[0252] like Fig.12 As shown, in situation 4, the above S1001 can be specifically implemented through the following S1203.

[0253] S1203. The first terminal device sequentially demodulates the multiple bit partitions in the third paging message based on the second preset rule until it demodulates the first bit partition including the identifier of the first terminal device or the identifier of the terminal device group to which the first terminal device belongs, and obtains the identifier of the first terminal device or the identifier of the terminal device group to which the first terminal device belongs from the first bit partition.

[0254] In a possible implementation, the second preset rule includes at least one of the following: demodulating in sequence from large to small according to the bit partition index value, demodulating in sequence from small to large according to the bit partition index value, and demodulating in sequence starting from a specified bit position.

[0255] In one example, the third paging message includes 3 bit partitions, namely bit partition #1, bit partition #2 and bit partition #3, and each bit partition includes 16 bits. The first terminal device first demodulates the 16 bits in bit partition #1. If the first type of terminal device identifier obtained by demodulation includes the identifier of the first terminal device, the first terminal device determines that the access network device pages the terminal device, and the first terminal device performs subsequent random access procedures and other operations. If the first type of terminal device identifier obtained by demodulation does not include the identifier of the first terminal device, the first terminal device continues to demodulate the 16 bits in bit partition #2, and the process is the same as the above process of demodulating the 16 bits in bit partition #1, until the first terminal device demodulates the identifier of the first terminal device or demodulates all 3 bit partitions in the paging message, and the first terminal device stops demodulating.

[0256] It should be pointed out that the above description uses the example of the first terminal device demodulating in the order of indexes from small to large. In specific implementation, the first terminal device can demodulate in any order, and this application does not limit this.

[0257] In another possible implementation, similar to the first preset rule, the second preset rule may also include Rule 3, calculating the position and quantity of the first bit sequence in the second paging message according to a preset calculation method. Rule 4, querying the position and quantity of the first bit sequence in the second paging message according to a preset record table. At this time, the understanding of the second preset rule can refer to the above-mentioned first preset rule, and this application will not elaborate on this.

[0258] In one example, the index Y of the bit partition satisfies Formula 4:

[0259] Y=NG-5G-S-TMSIdiv(s*2 k ) Formula 4

[0260] The preset record table is shown in Table 2 below:

[0261] Table 2

[0262] Scope of terminal equipment identification Index of bit partition <![CDATA[B1-B i ]]> 2

[0263] Among them, B1-B i is the identifier of the i-th terminal device, i is a positive integer, and Table 2 is used to characterize B1-B i The index of the bit partition corresponding to the i-th terminal device is 2.

[0264] In a possible implementation, based on the above scenario 3, before sending the paging message to the first terminal device, the access network device may also indicate the type of the paging message to the first terminal device, so that the first terminal device can demodulate the paging message using a corresponding demodulation method according to the type of the paging message. Fig.12 ,like Fig.13 As shown, the method also includes:

[0265] S1301: The access network device sends fourth indication information to the first terminal device. Correspondingly, the first terminal device receives the fourth indication information from the access network device.

[0266] The fourth indication information is used to indicate the type of the paging message; the type of the paging message includes: the third paging message or the fourth paging message; the fourth paging message is used to carry the second type of terminal device identification. Optionally, the number of bits of the third paging message and the fourth paging message can be the same, for example, the third paging message and the fourth paging message are both 48 bits; the number of bits of the third paging message and the fourth paging message can also be different, for example, the third paging message is 36 bits, and the fourth paging message is 48 bits; this application does not limit this.

[0267] After the first terminal device receives the fourth indication information, if it is determined that the type of the paging message indicated by the fourth indication information is the third paging message, the first terminal device demodulates one or more bit partitions in the third paging message to determine the first type of terminal device identifier. If it is determined that the type of the paging message indicated by the fourth indication information is the fourth paging message, the first terminal device directly demodulates the complete fourth paging message to determine the second type of terminal device identifier carried by the fourth paging message.

[0268] It should be noted that the signaling message carrying the fourth indication information is similar to the signaling message carrying the second indication information. The specific description thereof can refer to the description of the signaling message carrying the second indication information in S901 above, which will not be repeated here.

[0269] In a possible implementation, the first type of terminal device identification includes an identification of the terminal device (UE ID), or the first type of terminal device identification includes an identification of a terminal device group (UE Group ID). The second type of terminal device identification includes an identification of the terminal device, or the second type of terminal device identification includes an identification of a terminal device group.

[0270] When a paging message pages the first terminal device, the first type of terminal device identifier includes the identifier of the first terminal device; the bit partition to be demodulated is the first bit partition to which the identifier of the first terminal device belongs in the third paging message; or, the first type of terminal device identifier includes the identifier of the terminal device group to which the first terminal device belongs; the bit partition to be demodulated is the first bit partition to which the identifier of the terminal device group to which the first terminal device belongs in the third paging message.

[0271] In other words, if the paging message carries the identifier of the terminal device, the first terminal device determines that the paging message is for paging the first terminal device when demodulating the identifier of the first terminal device. If the paging message carries the identifier of the terminal device group, the first terminal device determines that the paging message is for paging the first terminal device when demodulating the identifier of the terminal device group to which the first terminal device belongs.

[0272] In a possible implementation, the paging message may also include an identifier of an access and mobility management network element (such as AMF).

[0273] Combined with the description of 5G-S-TMSI in the above-mentioned related technologies, it can be known that the current 5G-S-TMSI uniquely identifies the AMF through 16 bits and uniquely identifies the terminal device through another 32 bits. When paging a low-power terminal device, the LP-WUS used to paging the low-power terminal device needs to page the low-power terminal device through a 48-bit paging message. Taking the data transmission rate between the low-power terminal device and the access network device as 56kbps as an example, two slots are required to transmit the paging message of one terminal device. If the access network device needs to page 50 terminal devices, 100 slots are required to transmit the paging messages of 50 terminal devices. This will cause the LP-WUS in the network to occupy more transmission resources and cause higher paging delays for terminal devices. Moreover, in a shared network scenario, the AMF needs to be identified in the paging message to determine which AMF the terminal device that needs to be paged is connected to. However, in a scenario that does not support network sharing, or in a cell where the tracking area remains unchanged, there is only one AMF identifier for a cell. At this time, even if the paging message does not carry the AMF identifier, the other 32 bits can also uniquely identify the terminal device being paged.

[0274] Therefore, in the embodiment of the present application, after receiving the paging message, the first terminal device can first determine the type of the access network device. When the access network device type is a first type of access network device, the identifier of the access and mobility management network element in the paging message is demodulated; when the access network device type is a second type of access network device, the identifier of the access and mobility management network element in the paging message is not demodulated.

[0275] Optionally, when the paging message is a first paging message, the identifier of the access and mobility management network element is carried in the third bit sequence in the first paging message. At this time, when the access network device type is a first type of access network device, the third bit sequence in the first paging message is demodulated to obtain the identifier of the access and mobility management network element included in the first paging message; when the access network device type is a second type of access network device, the third bit sequence in the first paging message is not demodulated.

[0276] In the case where the paging message is the third paging message, the identifier of the access and mobility management network element is carried in the fourth bit sequence in the third paging message. At this time, in the case where the access network device type is the first type of access network device, the fourth bit sequence in the third paging message is demodulated to obtain the identifier of the access and mobility management network element included in the third paging message; in the case where the access network device type is the second type of access network device, the fourth bit sequence in the third paging message is not demodulated.

[0277] Optionally, the first type of access network device is a shared access network device, and the second type of access network device is a non-shared access network device.

[0278] Based on this, when the access network device is a shared access network device, one cell may correspond to multiple access and mobility management network element identifiers. At this time, if the terminal device does not demodulate the access and mobility management network element identifier in the first paging message, it may cause the terminal device with different access and mobility management network element identifiers but the same terminal device identifier to wake up, resulting in a false alarm. Therefore, when the access network device is a shared access network device, the terminal device demodulates the access and mobility management network element identifier in the first paging message, so that the terminal device can accurately determine the terminal device paged by the paging message, avoiding false alarms.

[0279] In the case where the access network device is a non-shared access network device, one cell corresponds to an access and mobility management network element identifier, and the access and mobility management network element identifiers in the paging message sent by the access network device are the same. At this time, even if the terminal device only demodulates the terminal device identifier, it can correctly determine the terminal device that the paging message is paging. Therefore, the terminal device may not demodulate the access and mobility management network element identifier in the first paging message when the access network device is a non-shared access network device, thereby reducing the number of bits that the terminal device demodulates the paging message, and further reducing the power consumption of the terminal device during the paging process.

[0280] It should be pointed out that the above embodiments are mainly explained by taking the example of a network entity (such as a core network device, an access network device, a terminal device) intercepting a first paging message from a second paging message to reduce the demodulation power consumption of a terminal device. In a specific implementation, when a core network device or an access network device pages a first type of terminal device, it can also generate a new terminal device identifier based on the first type of terminal device, and the number of bits occupied by the new terminal device identifier is less than the number of bits occupied by the original terminal device identifier. At this time, the above-mentioned first bit sequence, or bit partition carries a new terminal device identifier. The terminal device demodulates the paging message according to the generation rule of the new terminal device identifier to determine whether it is paged.

[0281] In other words, taking the access network device generating a new terminal device identifier as an example, after the access network device receives the second paging message from the core network device, it determines the terminal device to be paged by the second paging message. The access network device generates a new terminal device identifier corresponding to the paging terminal device. After that, the new terminal device identifier is carried in the first bit sequence of the first paging message, and the access network device sends the first paging message to the terminal device. After the terminal device receives the first paging message, it demodulates the first paging message to determine the new terminal device identifier carried by the first paging message, and demodulates the paging message according to the generation rule of the new terminal device identifier to determine whether it is paged. Alternatively, after the access network device generates a new terminal device identifier corresponding to the paging terminal device, the new terminal device identifier is carried in the bit partition corresponding to the paging terminal device in the third paging message, and the access network device sends the third paging message to the terminal device. After the terminal device receives the third paging message, it demodulates the third paging message to determine the new terminal device identifier carried by the third paging message, and demodulates the paging message according to the generation rule of the new terminal device identifier to determine whether it is paged.

[0282] It is understandable that the generation rule of the new terminal device identifier generated by the access network device can be pre-configured in the terminal device, or can be indicated to the terminal device through indication information. When the access network device indicates the generation rule of the new terminal device identifier to the terminal device through indication information, the indication information can be carried in one or more of the RRC signaling message, the MAC-CE signaling message, the DCI signaling message, and the SIB, and this application does not limit this.
