[0208] Figure 1 is a schematic diagram illustrating the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1 , communication system 100 may include a first network device, a second network device, and a terminal. Optionally, the aforementioned network device (i.e., the first network device or the second network device) may include at least one of an access network device and a core network device.

[0209] In some embodiments, the terminal includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0210] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a wireless fidelity (WiFi) system, but is not limited thereto.

[0211] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0212] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0213] In some embodiments, the core network device may be a device including one or more network elements, or may be multiple devices or a group of devices, each including all or part of one or more network elements. The network element may be virtual or physical. The core network, for example, includes at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC). Alternatively, the core network device may also be a location management function network element. Exemplarily, the location management function network element includes a location server (location server), which may be implemented as any one of the following: Location Management Function (LMF), Enhanced Serving Mobile Location Centre (E-SMLC), Secure User Plane Location (SUPL), and Secure User Plane Location Platform (SUPLLP).

[0214] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0215] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0216] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other paging methods, and next-generation systems based on these. Furthermore, a combination of multiple systems (e.g., a combination of LTE or LTE-A with 5G) may also be employed.

[0217] Optionally, a non-terrestrial network (NTN) system is introduced in the 5G communication system. The NTN system is widely used in the communication field due to its wide coverage, strong disaster resistance and large capacity. In the NTN system, wireless resources can be provided to the terminal by satellite (or drone). In addition, in the NTN system, the network device also needs to page the terminal. Optionally, the method for the network device to paging the terminal (hereinafter referred to as traditional paging or legacy paging or normal paging) may include: when the network device wants to perform related services on the terminal in an inactive state (INACTIVE) or idle state (IDLE), the network device sends a paging signal to the terminal, the terminal receives the paging signal, and accesses the network device to perform related services by responding to the paging signal. In some embodiments, when the network device sends a paging signal to the terminal, the network device will start the T3513 timer. When the network device receives a response from the terminal to the paging signal during the operation of the T3513 timer, it is determined that the paging is successful. If the T3513 timer times out and the network device still has not received a response from the terminal to the paging signal, it is determined that the paging has failed.

[0218] In some embodiments, in some special scenarios in the NTN system (e.g., in suburban and rural areas), paging failures to terminals may occur due to shadow fading and clutter loss. Specifically, in some embodiments, Line of Sight (LoS) probability indicates that at an elevation angle of 30 degrees, approximately 10% of rural users and 50% of urban users experience Non-Line of Sight (NLOS) between them and network devices, and clutter loss may cause NLOS exceeding 18 decibels (dB) between the terminal and the network device. When the NLOS loss reaches 18 dB, even if the terminal is still within the coverage area of ​​the satellite beam, it may still fail to detect the Single Side Band (SSB) signal, resulting in a Radio Link Failure (RLF). At this time, if the network device sends a paging signal to the terminal, the terminal may not be able to respond to the paging signal of the network device due to the inability to detect the paging signal. In addition, if the network device does not receive a response to the paging signal from the terminal for a long time, it will determine that the paging has failed and will page again. After a certain number of failed attempts, the network device will give up paging the terminal, which will result in a low paging success rate for the terminal in special scenarios of the NTN system, affecting the communication efficiency and communication services (such as public safety services) of the terminal.

[0219] In some embodiments, in order to improve the paging success rate of the terminal, enhanced paging (Robust paging) is introduced. Under enhanced paging, the network device can send an enhanced paging notification signal (Robust paging notification alert) to the terminal to achieve successful paging of the terminal under severe NLOS channel conditions. Optionally, the enhanced paging notification signal can be a downlink physical channel, which includes its own built-in system information and synchronization signal. For example, at least one of the information carried, physical resources, number of repetitions, and transmission power of the enhanced paging notification signal is different from the above-mentioned traditional paging (or called legacy paging, normal paging). For example, the enhanced paging is implemented by using a new synchronization signal and traditional paging. For example, the signal to noise ratio (SNR) of the physical downlink channel of the enhanced paging notification signal can be much lower than the SNR of the physical downlink channel of traditional paging. Optionally, in some embodiments, the enhanced paging notification signal can be understood as an enhancement to traditional paging. Compared to traditional paging signals, the enhanced paging notification signal is more likely to be detected by the terminal under severe NLOS channel conditions. Therefore, in some embodiments, after a certain number of traditional paging (legacy paging or normal paging) attempts fail, the network device can send an enhanced paging notification signal to the terminal. When the terminal receives the enhanced paging notification signal, it can move to a location with better channel conditions to respond to the paging, thereby improving the terminal's paging success rate.

[0220] However, how network equipment performs robust paging remains a pressing technical challenge. Furthermore, in a split radio access network (RAN) architecture, robust paging is typically performed by the generation NodeB distributed unit (gNB-DU). This is also a pressing technical challenge.

[0221] FIG2A is an interactive diagram of a paging method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a paging method for a communication system 100, the method comprising:

[0222] Step 2101: The second network device sends the eighth information.

[0223] Optionally, the second network device may send the eighth information to at least one first network device, and the first network device may receive the eighth information.

[0224] Optionally, the first network device and the second network device may both be located in the RAN notification area where the terminal is located. The second network device may be the last serving network device of the terminal, and the first network device may be a network device different from the second network device in the RAN notification area. For example, the second network device may be referred to as NG-RAN node 1, and the first network device may be referred to as NG-RAN node 2. When the first network device is NG-RAN node 2 and the second network device is NG-RAN node 1, the first network device and the second network device may communicate via XnAP signaling. Alternatively, in other embodiments, in a RAN CU-DU split architecture, the first network device may be a DU, for example, a gNB-DU, and the second network device may be a centralized unit (CU), for example, a gNB-CU. When the first network device is a gNB-DU and the second network device is a gNB-CU, the first network device and the second network device may communicate via F1AP signaling.

[0225] Optionally, the terminal in the embodiment of the present disclosure may be, for example, a terminal in a Radio Resource Control Inactive (RRC_Inactive) state or a Radio Resource Control Idle (RRC_Idle) state.

[0226] Optionally, the eighth information mentioned above can be used to instruct the first network device to perform a second paging on the terminal. The eighth information may include a paging identifier of the terminal. The eighth information may be, for example, a RAN Paging message. The eighth information may include a RAN Paging identifier of the terminal. The RAN Paging identifier may be, for example, an inactive radio network temporary identifier (I-RNTI). In addition, the second paging can be used to perform normal paging on the terminal. The normal paging may be, for example, the legacy paging (or normal paging) described in the previous embodiment of FIG. 2A. For a detailed introduction to the normal paging, please refer to the previous description of the embodiment of FIG. 2A and will not be repeated here.

[0227] Step 2102: The second network device and / or at least one first network device performs a second paging on the terminal based on the paging identifier.

[0228] Step 2103: The second network device sends the first instruction and / or the second information.

[0229] Optionally, the second network device may send the first indication and / or the second information to at least one first network device, and the first network device may receive the first indication and / or the second information.

[0230] Optionally, the first indication may be used to instruct the first network device to initiate a first paging of the terminal. Optionally, the first paging may be, for example, the enhanced paging (Robust paging) described previously in the embodiment of FIG. 2A , and the first indication may be, for example, an indication to initiate robust paging, or may be another name, which is not limited in this disclosure. Furthermore, in some embodiments, the first paging may be an enhanced paging of the second paging. Optionally, the first paging and the second paging differ in at least one of the following: associated synchronization signals, information carried, physical layer processing methods, physical resources, number of repetitions, or transmit power. For example, the SNR of the physical downlink channel of the first paging may be significantly lower than the SNR of the physical downlink channel of the second paging. Furthermore, compared to the second paging, the first paging is more likely to be responded to by the terminal under severe NLOS channel conditions. For example, compared to the second paging, the first paging is more likely to be responded to by the terminal under severe NLOS channel conditions in non-terrestrial wireless access coverage. For a detailed introduction to enhanced paging, please refer to the description before the embodiment of FIG. 2A , which will not be repeated here.

[0231] Optionally, in some embodiments, the second network device may send the first indication to the at least one first network device only when at least one of the following conditions is satisfied. Optionally, the at least one condition may include, for example:

[0232] Condition 1: The second network device does not receive a response message from the terminal to the second paging within the second time period.

[0233] Optionally, the second duration may be predefined and / or preconfigured by the protocol.

[0234] Optionally, in some embodiments, "not receiving a response message from the terminal to the second paging" herein may include: not receiving a response message from the terminal to the second paging initiated by the first network device; and / or not receiving a response message from the terminal to the second paging initiated by the second network device. Specifically, regarding the method for the second network device to determine whether a response message from the terminal to the second paging initiated by the first network device has been received, the method may include: after the first network device initiates the second paging, if the first network device receives a response message from the terminal to the second paging, the first network device will indicate to the second network device that the first network device has received the response message from the terminal. At this point, the second network device will know that it has successfully paged the terminal and can instruct other first network devices to stop the second paging in a timely manner to avoid unnecessary paging and waste of resources. Based on this, in some embodiments, when the second network device does not receive relevant information sent by the first network device "for indicating that the first network device has received the response message from the terminal" within a certain period of time, it can determine that the response message from the terminal to the second paging initiated by the first network device has not been received.

[0235] Condition 2: The second network device does not receive an access request from the terminal within the second time period;

[0236] Optionally, in some embodiments, "not receiving an access request from the terminal" may include: not receiving an access request from the terminal for a second paging initiated by the terminal to the first network device; and / or not receiving an access request from the terminal for a second paging initiated by the terminal to the second network device. The principle behind this is similar to the principle behind "not receiving a response message from the terminal to the second paging" described above and is not further elaborated here.

[0237] Condition three: the second network device determines that the terminal supports the first paging.

[0238] Optionally, the above “the terminal supports the first paging” may be understood as: the terminal supports the capability of receiving robust paging.

[0239] Optionally, the terminal may report to at least one of a network device (such as the aforementioned first network device and / or second network device) and a core network that the terminal supports a capability of receiving robust paging. Furthermore, the second network device may determine whether the terminal supports the first paging based on the terminal's report and on interaction with the first network device and / or the core network.

[0240] Condition four: the second network device receives a third indication sent by the core network, where the third indication may be used to instruct a first paging of the terminal.

[0241] Condition 5: The second network device determines that the terminal is located within the first coverage area.

[0242] Optionally, the first coverage area may be a coverage area where the first paging can be performed. The first coverage area may include at least one of one or more cells, one or more RAN notification areas, and one or more tracking areas. Optionally, the first coverage area may include the coverage area of ​​the first cell. Optionally, the cell type of the first cell may be a first cell type, which may be a cell type where the first paging can be performed; for example, the first cell type may be a cell type that supports robust paging. For example, the first cell type may be an NTN cell type, which may be an NTN cell. Optionally, the first cell type may be protocol-predefined and / or preconfigured.

[0243] Optionally, the location of the terminal can be a historical location or a predicted location of the terminal. For example, it can be the historical location of the terminal determined when the second network device last provided services to the terminal, or it can be the future location of the terminal predicted when the second network device last provided services to the terminal.

[0244] Condition six: The second network device determines that the cell type of the cell corresponding to the first network device is the first cell type.

[0245] Optionally, in some embodiments, the second information may include at least one of third information, fourth information, fifth information, sixth information, and seventh information. The third information, fourth information, and seventh information may be used to indicate conditions under which the first network device starts performing the first paging operation on the terminal, and the fifth information and sixth information may be used to indicate conditions under which the first network device stops performing the first paging operation. The third information, fourth information, fifth information, sixth information, and seventh information are described in detail below.

[0246] Optionally, the third information may be used to indicate the first cell type. For a detailed description of the first cell type, reference may be made to the description of the above embodiment. Furthermore, when the first network device receives the third information and determines that the cell type corresponding to the first network device is the first cell type indicated by the third information, the first paging may be initiated.

[0247] Optionally, the fourth information mentioned above can be used to indicate a third condition; the third condition can be a condition for starting the first paging of the terminal. In some embodiments, when the first network device receives the fourth information, if it is determined that the second paging of the first network device meets the third condition indicated by the fourth information, the first paging is started. The third condition can be used to indicate that the second paging was unsuccessful; the third condition can also be called, for example, the criterion information for starting robust paging, or can be other names, which are not limited in this disclosure. In some embodiments, the third condition can include at least one of the following: after the second paging of the first duration is performed, no response message and / or access request from the terminal to the second paging is received; after the second paging of the second number is performed, no response message and / or access request from the terminal to the second paging is received. Optionally, the first duration and the second number can be predefined and / or preconfigured by the protocol. Optionally, the above-mentioned "response message of the terminal to the second paging" may include: the response message of the terminal to the second paging initiated by the first network device, and / or, the response message of the terminal to the second paging initiated by the second network device; the above-mentioned "access request of the terminal to the second paging" may include: the access request of the terminal to the second paging initiated by the first network device, and / or, the access request of the terminal to the second paging initiated by the second network device. For a detailed introduction to this part, please refer to the above description.

[0248] Optionally, the fifth information mentioned above can be used to indicate the first number; the first number can be used to determine the conditions for stopping the first paging. In some embodiments, when the first network device receives the fifth information, if it is determined that the number of paging times of the first network device has reached the first number indicated by the fifth information, the first paging is stopped. The first number can also be called, for example, the number of times robust paging has continued, or other names, which are not limited in this disclosure.

In other embodiments, when the first network device receives the sixth information, if the first network device is performing the first paging, the first network device stops performing the first paging when it determines that the first absolute time indicated by the sixth information has arrived. The first time information can also be called, for example, the duration of robust paging, or other names, which are not limited in this disclosure. Optionally, the first time information can be predefined and / or preconfigured by the protocol.

[0250] Optionally, the seventh information may be used to indicate a first coverage area. The first coverage area may be at least one of one or more cells, one or more RAN notification areas, or one or more tracking areas. For a detailed description of the first coverage area, reference may be made to the above-described embodiment. Furthermore, upon receiving the seventh information, if the first network device determines that a cell in the first network device is within the corresponding first coverage area, the first paging operation may be initiated.

[0251] Step 2104: The first network device determines the second information.

[0252] In some embodiments, the second information may be received by the first network device from the second network device. In other embodiments, the second information may be determined by the second network device based on a preconfiguration. For example, the first network device may determine the second information based on an Operation, Administration, and Maintenance (OAM) configuration.

[0253] Step 2105: The first network device determines that the first condition is met based on the second information and / or based on the first indication, and starts a first paging of the terminal.

[0254] Optionally, in some embodiments, when the first network device receives the first indication, it may start to perform a first paging on the terminal. Alternatively, in other embodiments, when the first network device determines that a first condition is satisfied based on the second information, it may start to perform a first paging on the terminal. Optionally, the first condition may include at least one of the following:

[0255] The cell type of the cell corresponding to the first network device is the first cell type;

[0256] The second paging of the first network device satisfies a third condition;

[0257] The cell of the first network device is within the first coverage area.

[0258] For a detailed description of the first cell type, the third condition, and the first coverage area, please refer to the description of the above embodiment.

[0259] Optionally, the first network device may perform the first paging to the terminal based on the paging identifier.

[0260] It should be noted that, in some embodiments, since the second network device in the aforementioned step 2103 sends the first indication and / or second information to at least one first network device, in this step 2105, when it is determined based on the first indication and / or second information that the first condition is met, multiple first network devices will perform the first paging on the terminal respectively, so as to increase the paging success rate of the terminal.

[0261] Step 2106: The second network device sends a second indication and / or second information.

[0262] Optionally, the second network device may send a second indication and / or second information to at least one first network device, and the first network device may receive the second indication and / or second information. For a detailed description of the first network device, the second network device, and the second information, please refer to the above embodiment.

[0263] Optionally, the second indication may be used to instruct the first network device to stop performing the first paging. The second indication may be, for example, an indication to stop robust paging, or may be another name, which is not limited in the present disclosure.

[0264] Optionally, in some embodiments, the second network device may send the second indication to the at least one first network device only when at least one of the following conditions is satisfied. Optionally, the at least one condition may include, for example:

[0265] The second network device determines that the location of the terminal is not within the first coverage area;

[0266] The second network device receives ninth information sent by any first network device, wherein the ninth information is used to indicate that the first network device that sent the ninth information has received a response message and / or access request from the terminal to the first paging.

[0267] Specifically, in some embodiments, when any first network device receives a response message and / or access request from a terminal to a first paging, the first network device may send a ninth message to a second network device, so that the second network device can know, based on the ninth message, that a first network device has successfully paged the terminal. The second network device may then send a second instruction to other second network devices to instruct the other second network devices to stop the first paging. Since the first paging requires higher power consumption and network resources than the second paging, when the terminal paging is successful, the second network device promptly sends a second instruction to at least one first network device, so that the first network device promptly stops the first paging. This can avoid unnecessary paging power consumption, unnecessary resource waste, and improve resource utilization.

[0268] Step 2107: The first network device determines that the second condition is met based on the second information and / or based on the second indication, and stops performing the first paging on the terminal.

[0269] Optionally, in some embodiments, when the first network device receives the second indication, it may stop performing the first paging on the terminal. Alternatively, in other embodiments, when the first network device determines that a second condition is satisfied based on the second information, it may stop performing the first paging on the terminal. Optionally, the second condition may include at least one of the following:

[0270] The paging number of the first paging of the first network device reaches a first number;

[0271] The first network device meets the condition indicated by the first time information;

[0272] The first network device receives a response message from the terminal to the first paging;

[0273] The first network device receives an access request from the terminal for the second paging.

[0274] For a detailed introduction to this part, please refer to the above step description.

[0275] It should be noted that the method of the present disclosure can be applied to RAN paging scenarios and / or core network (CN) paging scenarios. Optionally, when the second network device sends the second information to the first network device, the second network device may be a RAN node, in which case the corresponding scenario is RAN paging. Alternatively, the second network device may be a core network device, for example, a network element of the core network, in which case the corresponding scenario is CN paging.

[0276] In the above embodiment, a method is provided for a first network device to start or stop performing a first paging on a terminal, wherein the first paging is used to perform paging enhancement on the terminal. It can be seen that the present disclosure provides a method for starting or stopping paging enhancement on a terminal. When the terminal is located in a network environment with poor channel conditions, the method of the present disclosure can be used to perform paging enhancement on the terminal, thereby improving the paging success rate of the terminal and ensuring the communication efficiency of the terminal. Moreover, after starting to perform paging enhancement on the terminal, the method of the present disclosure can also be used to stop performing paging enhancement on the terminal, thereby avoiding the occurrence of the situation where "resources are wasted due to performing paging enhancement on the terminal for a long time" and improving resource utilization.

[0277] The paging method involved in the embodiments of the present disclosure may include at least one of steps 2101 to 2107. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, step 2103 may be implemented as an independent embodiment, and step 2101+step 2102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

NG-RAN node 1 instructs NG-RAN node 2 to start or stop robust paging through the first information. It should be noted that the difference between the first information here and the first information of the aforementioned embodiment is that, in addition to including the content of the first information of the aforementioned embodiment, the first information here also includes the aforementioned first cell type.

[0395] Optional embodiment 1 of the present disclosure (determined based on NG-RAN node 1, i.e., the last serving gNB) is as follows:

[0396] Figure 5B is a schematic diagram illustrating an interaction of a paging method according to an embodiment of the present disclosure. As shown in Figure 5B , the RAN Paging process is triggered by NG-RAN node 1 sending a RAN Paging message to NG-RAN node 2, which includes necessary information such as the UE RAN Paging identity.

[0397] If the first information is included in the RAN Paging message, NG-RAN node 2 determines whether to perform Robust paging according to the first information.

[0398] The first information includes at least one of the following information:

[0399] -Start robust paging indication, used to indicate the start of robust paging information;

[0400] - Stop robust paging instruction, used to indicate information to stop robust paging;

[0412] The RAN Paging procedure is triggered by NG-RAN node 1 by sending a RAN Paging message to NG-RAN node 2, which should provide necessary information such as UE RAN Paging identity.

[0413] NG-RAN node 2 determines whether to perform robust paging based on the second information.

[0414] The NG-RAN node 2 may confirm the second information in the following manners, including:

[0415] - Receive the second information from NG-RAN node 1

[0416] - Confirm the second information based on OAM configuration

[0417] The second information includes at least one of the following information:

[0418] - Information about the number of times robust paging has been continued, which is used by NG-RAN node 2 to stop robust paging after the number of paging times reaches the indicated number;

[0420] - Robust paging duration information, which is used by NG-RAN node 2 to stop robust paging according to the indicated time after starting robust paging;

[0421] In some embodiments, the criteria for initiating robust paging include at least one of time information and number of times information, wherein the time information or the number of times information is a criterion for determining whether to initiate robust paging. For example, if no response is received from the UE after a certain period of normal paging, robust paging is initiated; for another example, if no response is received from the UE after a certain number of normal paging times, robust paging is initiated.

[0422] Optional Embodiment 3 of the present disclosure (gNB-CU decision in RAN split architecture):
