In the NTN network, the cellular cell moves rapidly with the high-speed movement of the satellite.

[0177] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0178] In the embodiments of the present application, the term "a plurality of" refers to two or more, and other quantifiers are similar thereto.

[0179] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0180] The embodiments of the present application provide a paging method and apparatus, which avoid the terminal from frequently performing cell reselection, downlink synchronization, and reading system information, and reduce the power consumption of the terminal.

[0181] Among them, the method and the apparatus are based on the same inventive concept. Since the principles of solving problems by the method and the apparatus are similar, the implementation of the apparatus and the method can be referred to each other, and the repeated parts will not be described again.

[0182] The technical solutions provided by the embodiments of the present application can be applied to multiple systems. For example, the applicable systems can be a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, a Long Term Evolution Advanced (LTE-A) system, a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) system, a 5G New Radio (NR) system and its evolved communication systems, etc. These multiple systems may include terminal devices and network devices. The system may also include a core network part, such as an Evolved Packet System (EPS), a 5G System (5GS), etc.

[0183] The terminal device involved in the embodiments of the present application can be a device that provides voice and / or data connectivity to users, such as a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device can be called a User Equipment (UE). The wireless terminal device can be a USB storage device, other personal computer memory devices, and dongles, and can also communicate with one or more core networks (CN) via a Radio Access Network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted mobile device that exchanges voice and / or data with the wireless access network. For example, devices such as Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistant (PDA), personal computers, tablets, Machine-type Communication (MTC) terminal devices, etc. The wireless terminal device can also be called a system, subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, and wireless access points and routers / modems that meet the limitations of this definition, etc., which are not limited in the embodiments of the present application.

[0184] The network device involved in the embodiments of the present application may be an access network device, such as a base station. The base station may include multiple cells that provide services to terminals. According to different specific application scenarios, the base station may also be referred to as an access point, or may be a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names. The network device can be used to mutually replace the received air frames and Internet Protocol (IP) packets, and act as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be an evolved network device (eNB or e-NodeB) in a Long Term Evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), etc., or may also be a Home evolved Node B (HeNB), a relay node, a femto, a pico, a network test device, etc. The embodiments of the present application do not limit this. In some network architectures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated. The network device involved in the embodiments of the present application may be a Core Network device.

[0185] In the embodiments of the present application, the terminal device sends relevant information or similar descriptions to the network-side device, which only indicates that the relevant information is sent in the form of a wireless signal, and the intended recipient is the network device. The network device can obtain the relevant information by receiving the wireless signal.

[0186] In a satellite communication system, there are two working modes: one is the transparent relay mode, as Figure 1 shown. In this mode, the satellite only transparently relays the signal without any processing. The terminal communicates with the gateway station, that is, the satellite only performs operations such as frequency conversion and wireless signal amplification on the uplink / downlink signal, and its function is similar to that of a radio frequency relay. The other is the regenerative communication mode, as Figure 2 shown. In this mode, the satellite can detect the information of the received signal, process and forward it, complete the function of the base station, and connect the terminal and the gateway station. That is, the satellite can perform functions such as frequency conversion, wireless signal amplification, encoding / modulation, and demodulation / decoding on the uplink / downlink signal. That is to say, the satellite can have all or part of the functions of the gNB and can regenerate the signal.

[0187] There are different cell types in NTN. The Earth-Fixed cell means that the ground coverage area of the satellite's serving cell does not change with the movement of the satellite within a certain period of time. That is, in the "staring" mode, the satellite is moving, but within a certain period of time, the satellite is "staring" at a certain area on the ground. As Figure 3 shown in, the satellite moves from time T1 to time T2, and the coverage area of the satellite on the ground is always A. In this scenario, as the satellite moves, the angle between the satellite antenna and the ground changes with the movement of the satellite, so as to ensure that the area covered by the satellite antenna remains unchanged. The quasi-Earth Fixed cell is similar to the Earth-Fixed cell, the difference being that the time when the satellite "stares" at the ground is relatively shorter, that is, the interval between T1 and T2 is shorter. And the Earth-moving cell means that the ground coverage area of the satellite's serving cell changes with the movement of the satellite. As Figure 4 shown in, the coverage area of the satellite is A at time T1 and B at time T2. In this scenario, as the satellite moves, the angle between the satellite antenna and the ground hardly changes.

[0188] Whether it is the above quasi-Earth-Fixed cell or the Earth-moving cell, as the satellite moves, the cell mapped by the satellite to the ground will move quickly. The difference is that the former does not move within a certain period of time, but in the long run, the cell also moves quickly, and the latter is constantly moving quickly. For the terminal, when the cell changes, the terminal needs to perform cell reselection, complete synchronization with the new cell, and read the system message of the new cell in order to timely monitor the paging of the network. Frequent cell reselection brings a great burden to the terminal and increases the power consumption of the terminal.

[0189] In view of the above problems, the embodiment of the present application proposes a paging method, which uses time-related configurations to send and receive paging messages, reduces the dependence of paging message sending and receiving on cell configurations, so that the terminal does not need to care about cell changes and does not need to perform cell reselection.

[0190] Figure 5 is a schematic flow of a paging method provided by the embodiment of the present application Figure 1 As Figure 5 shown in, the method includes:

[0191] S501. The core network device obtains paging-related configurations, and the paging-related configurations include a first time, and the first time is used to determine the time slot for the terminal to monitor paging messages.

[0192] Optionally, the paging-related configuration may be determined by the core network device and / or the access network device. That is, the paging-related configuration includes: a first part determined by the core network device, and / or a second part determined by the access network device. Optionally, the part of the configuration determined by the access network device, such as a base station, is referred to as the access network configuration (RAN-Configuration) or the base station configuration (BS-Configuration). For convenience of description, the base station or the base station configuration (BS-Configuration) will be used as an example for subsequent description. By way of example, the BS-Configuration may include: cell-specific configuration in the paging message, default paging cycle, number of paging time slots within a paging cycle, configuration related to paging early indication (PEI) or wake-up signaling (WUS), configuration of the physical downlink control channel (PDCCH) related to paging, etc. The part of the configuration determined by the core network is referred to as other configuration (Other-Configuration). By way of example, the Other-Configuration may include: UE-specific paging cycle, UE-specific WUS or PEI configuration, etc. The core network device may obtain the above BS-Configuration from the base station side. It should be noted that in the embodiments of the present application, it is not limited to what specific information is included in the configurations determined by the core network device and the access network device respectively. The above is only an example.

[0193] Optionally, when the method for the core network device to obtain the BS-Configuration from the base station is applied to the transparent transmission scenario of earth-fixed cells, for the ground fixed area, the ground base station may have a determined BS-Configuration, which is determined by the ground base station and does not change according to the specific satellite or satellite cell covered.

[0194] Optionally, the paging-related configuration can be regional, that is, the paging-related configuration for a specific ground area is the same, regardless of how the satellite cells covering the ground area change, and this configuration is determined. Of course, the paging-related configuration for the specific ground area can be updated. Or rather, for a specific ground area, its paging-related configuration is related to the specific ground area and does not change with the change of the satellite or satellite cells covering the ground area. Of course, the paging-related configuration corresponding to the specific ground area can be the same within a certain period of time; it can change or be updated after a certain period of time. For the satellite cells covering the ground area, whether in transparent mode or regeneration mode, the paging messages are sent using this configuration. If a satellite cell (Cell) crosses the boundary and covers two ground areas (Area 1 and Area 2), as Figure 6 shown, the satellite cell can choose to use the paging-related configurations of the two ground areas respectively to send paging messages. That is: for paging the terminals in Area 1, the paging messages are sent using the paging-related configuration corresponding to Area 1, and for paging the terminals in Area 2, the paging messages are sent using the paging-related configuration corresponding to Area 2.

[0195] Optionally, the paging-related configuration is bound to the ground area or tracking area (TA) where the terminal is located. One TA corresponds to one ground area and one paging-related configuration. Then, when the satellite cell covers the corresponding ground area, the paging-related configuration corresponding to the ground area is used.

[0196] Optionally, the core network device and / or access network device can update the paging-related configuration. For example, an update period can be predefined, and the paging-related configuration is updated based on the update period, and the paging-related configuration does not change within the update period. If the core network device and / or access network device needs to update the paging-related configuration, it is necessary to ensure that all relevant terminals can obtain the updated paging-related configuration.

[0197] Optionally, the configuration related to paging messages can be fixed, for example, as specified in the standard.

[0198] Optionally, the first time in the paging-related configuration is an absolute time. Thus, the terminal can determine the time slot for the terminal to monitor paging messages based on this absolute time. This absolute time can be, for example, UTC (Universal Time Coordinated) time. That the first time in the paging-related configuration is an absolute time can be understood as that the first time indicates a UTC time. For example, it indicates a value of UTC seconds in units of 10 milliseconds, and this value is calculated starting from the midnight between December 31, 1899 (Sunday) and January 1, 1900 (Monday) of the Gregorian calendar date. Of course, it can also be other forms of absolute time, which is not limited in this application. It only requires that when not receiving the cell system message, the device sending the paging message (such as the access network device) and the device receiving the paging message (such as the terminal) have a clear, accurate, and common understanding of the transmission time slot of the paging message.

[0199] S502. The core network device sends paging-related configuration to the terminal.

[0200] Optionally, during the registration process or TA update (Tracking Area Update) process of the terminal, the core network device sends paging-related configuration to the terminal. That is, the terminal can obtain the paging-related configuration during the registration process or TA update process.

[0201] S503. The core network device sends a first paging message to the access network device, and the first paging message includes the paging-related configuration.

[0202] Optionally, when part of the paging-related configuration is determined by the access network device (such as a base station) and the other part is determined by the core network device, the first paging message includes the paging-related configuration determined by the core network device. For example, the first paging message includes the aforementioned Other-Configuration.

[0203] Exemplarily, referring to Figure 7As shown, when the base station sends BS-Configuration to the core network device, the core network device sends paging-related configurations to the terminal during the terminal registration process, including BS-Configuration and Other-Configuration. The core network device sends a first paging message to the base station, which includes Other-Configuration. The base station sends the paging message to the terminal via the gateway station and satellite. When the base station does not send BS-Configuration to the core network device, the core network device sends paging-related configurations to the terminal during the terminal registration process. All the paging-related configurations are determined by the core network device. The core network device sends a first paging message to the base station, which includes the paging-related configurations. The base station sends the paging message to the terminal via the gateway station and satellite.

[0204] S504. The access network device sends a paging message to the terminal based on the paging-related configurations.

[0205] When all the paging-related configurations are determined by the core network device, the access network device sends a paging message to the terminal based on the paging-related configurations in the first paging message. When some of the paging-related configurations are determined by the access network device and the other part is determined by the core network device, the access network device sends a paging message to the terminal based on the paging-related configurations carried in the first paging message and the paging-related configurations determined by itself. That is, the access network device determines the time slot for sending the paging message based on the paging-related configurations and sends the paging message to the terminal according to the determined time slot for sending the paging message. The method for the access network device to determine the time slot for sending the paging message is the same as the method for the terminal to determine the time slot for listening to the paging message.

[0206] S505. The terminal listens to the paging message based on the paging-related configurations.

[0207] The terminal determines the time slot for listening to the paging message based on the first time in the paging-related configurations, and then listens to the paging message based on this time slot. For example, it listens to the control channel (such as PDCCH) to obtain the paging message. The first time in the paging-related configurations of different terminals can be the same or different.

[0208] It should be noted that in S504, the access network device sends the paging message to the terminal according to the time slot it determines for sending the paging message. In S505, the terminal listens to the paging message according to the time slot it determines for listening to the paging message. The access network device and the terminal perform corresponding operations based on the time slots determined by themselves. The labels of S504 and S505 in the above method flow are not used to limit the chronological order of S504 and S505.

[0209] Optionally, the paging-related configuration includes a paging cycle (duration); based on the first time and the paging cycle, the terminal determines the time slot for the terminal to monitor paging messages, and monitors the paging messages according to the determined time slot for the terminal to monitor paging messages.

[0210] Exemplarily, the determined paging time slot can be the first time + k * duration, where k is an integer starting from 0, or the first time + (k - 1) * duration, where k is an integer starting from 1. When the first time is an absolute time, the absolute time of the time slot for the UE to monitor paging messages calculated according to the above method is obtained. For example, the absolute time of the first time slot for the terminal to monitor paging messages is the first time, the absolute time of the second time slot for the terminal to monitor paging messages is the first time + duration, the absolute time of the third time slot for the terminal to monitor paging messages is the first time + 2 * duration, and so on.

[0211] Optionally, the first time is the time corresponding to the first paging time slot, and the first paging time slot is the time slot for the terminal to monitor paging messages. Denote the time corresponding to the time slot for the terminal to monitor paging messages as PO (Paging Occasion). Then, the time of the next time slot for monitoring paging messages is: PO = PO + duration, and the time of each time slot for monitoring paging messages can be obtained by continuously iterating according to the above formula.

[0212] Optionally, the paging-related configuration includes the paging cycle and the interval between paging time slots; based on the first time, the paging cycle, and the interval between paging time slots, the terminal determines the time slot for the terminal to monitor paging messages, and monitors the paging messages according to the determined time slot for the terminal to monitor paging messages.

[0213] Exemplarily, the first time is the time corresponding to the original starting point of the paging time slot, such as what is called the epoch time, in units of duration, epoch time + N * duration, where N takes integers starting from 0, or epoch time + (N - 1) * duration, where N takes integers starting from 1, is the starting point of a paging cycle. If there are m paging time slots in a paging cycle and the interval between each paging time slot is gap, then the time of each paging time slot is epoch time + N * duration + M * gap, where M takes integers from 0 to m - 1, or epoch time + (N - 1) * duration + (M - 1) * gap, where M takes integers from 1 to m. The above parameters can all be obtained when the terminal registers, and the terminal does not need to read them from the broadcast cell of the cell. Optionally, the terminal can use the identifier of the terminal to determine a paging time slot from multiple paging time slots of the paging cycle as the time slot for the terminal to listen for paging messages. For example, the number of the time slot for the terminal to listen for paging messages is determined by the following formula: Seq = floor(UE_id / m), or Seq = UE_id mod m, where UE_id is the identifier of the terminal and m is the number of paging time slots in a paging cycle.

[0214] Optionally, referring to Figure 8 As shown, within the ground area covered by the same satellite cell, there are terminals at different positions. After the paging messages are simultaneously transmitted from the satellite, the time for the paging messages to reach terminals at different positions is different because the distances of terminals at different positions from the satellite are different and the propagation delays are also different. In addition, when the terminal moves within the same satellite cell, it does not need to inform the network. Therefore, the network does not know the position of the terminal in the cell. Moreover, even if the position of the terminal remains unchanged, as the satellite moves, the distance from the terminal to the satellite also changes. Therefore, the following one or more items can be included in the paging-related configuration: the time advance amount for listening for paging messages, the time delay amount for listening for paging messages, or the time window length for listening for paging messages. Thus, the terminal can listen for paging messages in advance or with a delay, or can listen for paging messages according to a certain time window length.

[0215] The time advance amount and the time delay amount are relative to the first time. Exemplarily, the time corresponding to the time slot for the terminal to listen for paging messages is the first time + n * duration. In the case where the time advance amount or the time delay amount is configured, then the terminal starts listening for paging messages in advance before the first time + n * duration according to the time advance amount or the terminal starts listening for paging messages after the first time + n * duration according to the time delay amount. In the case where the time window length is configured, the terminal starts listening for paging messages at the first time + n * duration and lasts for the time window length.

[0216] Optionally, in the case where the time advance, time delay, or time window length is not configured, the terminal can also determine the start time and end time of listening on its own based on the time corresponding to the time slot for listening to the paging message determined by the terminal. For example, the terminal can determine the propagation delay of the paging message, that is, the time required for the paging message to leave the satellite and reach the terminal, based on its own position and the position of the satellite cell, and then determine the time to receive the paging message. For example, if the satellite cell sends a paging message at the first time T, and the propagation delay of the paging message determined by the terminal is t, then the terminal can start listening to the paging message at the time corresponding to T + t or after the time corresponding to T + t.

[0217] Optionally, the paging-related configuration includes a pilot signal. The terminal listens to the pilot signal based on the paging-related configuration. In the case of detecting the pilot signal, the terminal listens to the control channel (such as PDCCH), and the control channel is used to schedule the paging message. That is, the terminal listens to the pilot signal based on the paging-related configuration and listens to the control channel according to the detected pilot signal. The pilot signal is used to assist the terminal in obtaining synchronization and assisting in the reception of the control channel. Optionally, the pilot signal can be a WUS signal, and the WUS signal can be a sequence. Optionally, the terminal can first listen to the WUS signal. If the WUS signal is detected, then it listens to the control channel for paging scheduling; if the WUS signal is not detected, the terminal does not listen to the control channel for paging scheduling.

[0218] Optionally, the paging-related configuration includes the time to stop listening to the paging message based on the paging-related configuration, and / or the paging message includes first indication information for indicating that the terminal stops listening to the paging message based on the paging-related configuration after accessing the next cell. Among them, the time to stop listening to the paging message based on the paging-related configuration is the time when the terminal exits the paging mechanism based on the first time in the above embodiments of the present application. Because some satellite cells may not support the above mechanism based on the first time, the terminal needs to fallback to the traditional mechanism in the related art to listen to the paging message. The above paging mechanism based on the first time can be predictive. Assuming that the network can know which satellite cells do not support the above mechanism and the network knows when the above satellite cells reach the position of the terminal, the network can thus indicate in the paging-related configuration the time to stop listening to the paging message based on the paging-related configuration. The first indication information indicates to the terminal through the paging message that the next satellite cell does not support the above time-based paging mechanism, and the terminal needs to, for example, fallback to the traditional or existing mechanism to listen to the paging message.

[0219] Optionally, the terminal may report to the core network device whether the terminal capabilities support the above paging mechanism based on the first time and / or whether the terminal expects to use the above paging mechanism based on the first time to monitor paging messages, that is, the terminal sends second indication information to the core network device, and the second indication information is used to indicate that the terminal supports and / or expects to monitor paging messages based on the paging-related configuration. Optionally, the network may send indication information indicating whether it supports the paging mechanism based on the first time in the above embodiments. Whether the network supports here includes whether the access network device supports and / or whether the core network device supports. Optionally, when registering, the terminal indicates to the core network device whether it supports and / or wishes to use the paging mechanism based on the first time. If the network supports (including the core network device supports and the cell where the terminal is located supports), the network sends paging-related configuration to the terminal, otherwise, the network does not send paging-related configuration to the terminal. Correspondingly, if the terminal does not receive the paging-related configuration, it is considered that the network does not support the paging mechanism based on the first time. The paging mechanism based on the first time may also be referred to as the paging mechanism based on absolute time.

[0220] The terminal determines the time slot for monitoring paging messages based on the time in the paging-related configuration. Thus, the terminal's monitoring of paging messages no longer depends on the cell configuration, and the terminal no longer continuously monitors system messages. Then, the terminal cannot determine the change of the TA it is in through the TA code (TAC) broadcast by the system message. Then, it is necessary to let the terminal know the geographical area of the current TA or TA list it is in. When the terminal exceeds the geographical area of the TA or TA list it is in, TA update needs to be performed. That is, the paging-related configuration includes the geographical area of the tracking area or tracking area list where the terminal is located. However, the change of the TA where the terminal is located no longer depends on receiving system messages to determine, but is determined by the terminal itself, such as according to its own location and the definition of the TA area.

[0221] In the paging method of the embodiments of the present application, paging messages are sent and received using time-related configuration, reducing the dependence of paging message sending and receiving on cell configuration information, enabling the terminal not to care about cell changes and not to perform cell reselection, and reducing terminal power consumption. This is especially important for the terminal to camp on the NTN cell. Through this mechanism, the enthusiasm of the UE to camp on the NTN cell can be improved, and the utilization rate of the NTN system can be increased.

[0222] Optionally, if the terminal has more than one receiver, the terminal can use one of the receivers to monitor paging messages in the NTN cell and use the other receiver to complete synchronization with a TN cell and receive system information. However, the terminal does not perform a cell reselection process in the TN network, and the timing of the terminal's synchronization with the TN cell or receiving system information is determined by the terminal. In this case, if the terminal monitors a paging message in the NTN network, the terminal can complete network access through the TN network in a timely manner. If the terminal accesses the network through the TN network, the TN network needs to promptly inform the NTN network so that the NTN network can stop paging in a timely manner, as Figure 9 shown. Of course, the terminal can also choose to access the network in the NTN cell. For example, after the terminal receives a paging message, it completes synchronization with the NTN cell and receives system information, and then performs network access.
