Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to a paging method, apparatus, and processor-readable storage medium. Background Technology

[0002] User equipment (UE), also known as terminal equipment. UE paging capability refers to the terminal equipment's ability to receive paging messages in a wireless communication network.

[0003] In current communication protocols, during the registration process with the mobile communication network, the terminal device reports its UE radio capability to the access network device. Based on the reported UE radio capability, the access network device generates UE radio capability for paging information and reports this information to the core network device. This information is then used by the network-side device to send paging messages to the terminal device. In practice, different versions of access network devices have different paging characteristics. For example, higher versions of access network devices may possess paging characteristics not found in lower versions. If the terminal device initially registers with a lower version of the access network device, while the paging terminal device uses a higher version, this difference in paging characteristics can cause inconsistencies between the paging characteristics used by the access network device when paging the terminal device and the paging information being monitored by the terminal device, leading to paging failure.

[0135] Figure 6 A schematic diagram of another paging device provided by some embodiments of the present disclosure is shown. Detailed Implementation

[0136] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown herein can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0137] In related technologies, the access network device generates UE radio capability for paging information based on the received terminal device radio capability, and reports this information to the core network device in the form of a container. Subsequently, the core network device transmits the UE radio capability for paging information to the access network device during the initial context establishment process.

[0138] When a core network (Access and Mobility Management Function) device triggers core network paging (CN paging), it transmits the radio paging capability information of the terminal device to be paging to the access network device. The access network device then paging the terminal device based on the received radio paging capability information. Similarly, when an access network (Radio Access Network) device triggers access network paging (RAN paging), it also transmits the radio paging capability information of the terminal device to other adjacent access network devices. These adjacent access network devices then paging the terminal device based on the received radio paging capability information.

[0139] In fifth-generation (5G) communication protocols, the wireless paging capabilities of terminal devices have been enhanced since Release 17, including support for Paging Early Indication (PEI) and 2RxXR capabilities. Furthermore, higher versions introduce other paging enhancements. If a terminal device is a higher version device supporting a paging feature introduced in that version, but the access network device used for initial registration is a lower version, according to the current paging process, although the initially registered access network device will send the terminal device's wireless paging capability information to the core network device, because the initially registered access network device is a lower version, the generated terminal device wireless paging capability information will not include the paging feature introduced in the higher version. This will result in the core network device being unable to obtain the paging feature introduced in the higher version. When the core network device subsequently triggers CN paging, even if the access network device used to page the terminal device is a higher version access network device that supports the paging features introduced in the higher version, the higher version access network device will assume that the terminal device does not support a certain paging feature introduced in the higher version because the radio paging capability information of the terminal device received from the core network device does not include that paging feature. Therefore, it will not use the higher version paging feature to page the terminal device. However, the terminal device, because the access network device paging the terminal device supports the higher version paging feature, will use the higher version paging feature to listen for paging. This leads to a discrepancy between the paging features used by the access network device to page the terminal device and the paging features used by the terminal device to listen for paging, resulting in paging failure.

[0140] Furthermore, if the access network equipment is an older version, when it triggers RAN paging, the terminal device radio paging capability information of the terminal device to be paged transmitted to other adjacent access network equipment will not carry the paging features introduced in the newer version. This will also cause inconsistencies in the paging features used by the terminal device to listen for paging when other higher version access network equipment uses RAN paging to page the terminal device, resulting in paging failure.

[0141] Furthermore, the differences in paging characteristics caused by the different versions of the access network device initially registered by the terminal device or the access network device that released the terminal device into the RRC inactive state, and the access network device of the paging terminal device, will result in inconsistent paging characteristics used by the access network device to paging the terminal device and the terminal device to listen for paging, leading to paging failure.

[0142] Based on the above research, this disclosure provides a paging method and apparatus that synchronizes wireless paging capabilities between access network equipment and user equipment. This wireless paging capability can indicate the paging characteristics that the user equipment can use, thereby enabling the network-side equipment to paging the terminal equipment according to the paging characteristics when paging the terminal equipment, thus avoiding paging failures caused by inconsistencies in the paging characteristics used by the network-side equipment when paging the terminal equipment and by the terminal equipment when listening for paging.

[0143] The method and apparatus are based on the same disclosed concept. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and repeated parts will not be described again.

[0144] The shortcomings of the above solutions are the result of the author's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure below should be considered as contributions made by the author to this disclosure.

Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0152] To facilitate understanding of this embodiment, a paging method disclosed in this disclosure will first be described in detail.

[0153] See Figure 1 The diagram shows a flowchart of a paging method provided in an embodiment of this disclosure. This method is applied to a terminal device and includes steps S101 to S102, wherein:

[0154] S101: Synchronize wireless paging capability with network-side equipment; wireless paging capability indicates the paging features that the terminal equipment can use;

[0155] S102: Receive paging messages based on synchronized wireless paging capabilities.

[0156] In the paging method provided in this embodiment, wireless paging capabilities are synchronized between the terminal device and the network-side device; these wireless paging capabilities refer to the paging features that the terminal device can use. When the terminal device subsequently receives a paging message, it can receive the paging message based on the synchronized wireless paging capabilities, thereby avoiding paging failures caused by inconsistencies in the paging features used by the network-side device when paging the terminal device and by the terminal device when listening for paging.

[0157] The paging method provided in this disclosure will be described in detail below through different optional embodiments.

[0158] In practical implementation, when a terminal device synchronizes its wireless paging capability with a network-side device, it can either synchronize the wireless paging capability from the terminal device to the network-side device, or the network-side device can synchronize the wireless paging capability from the terminal device. The wireless paging capability synchronized between the terminal device and the network-side device can be a basic paging capability (also known as a basic paging feature) or a paging enhancement capability (also known as a paging enhancement feature). A basic paging capability, for example, refers to the basic performance of the core network in a communication system being able to successfully initiate paging and ensure that terminal devices in an idle or inactive state receive the paging message. A paging enhancement capability, for example, is a more advanced paging performance achieved by optimizing and improving the paging mechanism based on the basic paging capability through the introduction of new technologies, methods, or functions. Examples include features such as Early Paging Indication (EPI), Sub-grouping, and Cross-slot scheduling introduced in 5G Release 17.

[0159] Normally, when a terminal device registers with a network-side device, it reports its paging capabilities to the access network device. The access network device then generates a radio capability forpaging for the terminal device based on the reported paging capabilities and reports it to the core network device. In this embodiment, the synchronization of radio paging capabilities between the terminal device and the network-side device can be performed after the terminal device has completed its registration with the network-side device.

[0160] For example, after a terminal device registers with the network-side device and connects to the communication network, it can periodically synchronize its wireless paging capabilities with the network-side device. This ensures the consistency of the paging features used by the terminal device and the network-side device during the paging process, thus avoiding paging failures caused by inconsistencies in the paging features used by the terminal device and the network-side device during the paging process.

[0161] Alternatively, when the network-side device synchronizes its radio paging capability with the terminal device, this synchronization can be triggered by certain specific events. For example, if the access network device discovers that the UE radio capability forpaging transmitted by the core network device or other adjacent access network devices for a certain terminal device does not match the paging characteristics of its own version, the access network device can proactively trigger the synchronization of its radio paging capability with that terminal device. This ensures consistency in the paging characteristics used by the terminal device and the network-side device regardless of which access network device is used to paging the terminal device. Furthermore, the access network device and the terminal device can also synchronize their radio paging capabilities under other events; the specific access events are not limited in this embodiment.

[0162] A1: For situations where network-side devices synchronize wireless paging capabilities to terminal devices, the following method can be used: receiving a dedicated message sent by the network-side device; determining whether the terminal device can use paging enhancement features based on whether the dedicated message carries first indication information and / or second indication information.

[0163] In practical implementation, a dedicated message refers to a message specifically sent for a particular terminal device or a specific communication scenario or function. When the network-side device triggers and the terminal device synchronizes its wireless paging capability, the network-side device can send a dedicated message to the terminal device. This dedicated message includes indication information indicating whether the terminal device can use the paging enhancement feature.

[0164] This specialized message may include, for example, a Radio Resource Control (RRC) Release message. The primary function of the RRC Release message is to terminate the RRC connection between the terminal device and the access network device. When the terminal device no longer needs to communicate with the network, or when the network decides to release the connection with the terminal device, it uses the RRC Release message to complete the connection release process, thereby releasing related radio resources such as radio channels and power. When sending the RRC Release message to the terminal device, the network device can include indication information within the message. Furthermore, since the RRC Release message is sent to the terminal device multiple times, the terminal device typically determines whether it can use paging enhancement features based on the indication information carried in the most recently received Release message.

[0165] In addition, indication information can also be carried in other RRC layer-specific messages, or Non-Access Stratum (NAS)-specific messages, or Packet Data Convergence Protocol (PDCP) layer-specific messages, without limitation in the embodiments disclosed herein.

[0166] Whether a dedicated message can indicate whether the paging enhancement feature can be used can be achieved by whether the dedicated message carries a first indication information, by the specific indication content of the second indication information carried in the dedicated message, or by a combination of carrying the first and second indication information.

[0167] a1: For cases where the availability of paging enhancement features is indicated by whether a first indication message is carried in the dedicated message:

[0168] If the dedicated message carries the first indication information, it means that the terminal device can use the paging enhancement feature corresponding to the first indication information; if the dedicated message does not carry the first indication information, it means that the terminal device cannot use the paging enhancement feature corresponding to the first indication information.

[0169] When the first indication message indicates whether a terminal device can use paging enhancement features, it may be, for example, an identification identifier related to the paging enhancement feature, to indicate which specific paging enhancement feature the terminal device can use. This identification identifier may be, for example, an identifier used to distinguish different paging enhancement features, such as type information, and is not limited in this embodiment. For example, suppose there are four paging enhancement features A, B, C, and D, where the identification identifier for A is 00, the identification identifier for B is 01, the identification identifier for C is 10, and the identification identifier for D is 11; if the indication information included in the dedicated message is "00" and "11", then the indication message indicates that the paging enhancement features that the terminal device can use include A and D; since the indication information does not carry the identification identifiers for B and C, the terminal device cannot use paging enhancement features B and C.

[0170] The first indication information can indicate that multiple paging enhancement features within a certain range are available; or it can specifically indicate whether a single paging enhancement feature is available. For example, when the first indication information is "IE", it means that the terminal device can use all paging enhancement features within a certain range; when the first indication information is "IE1", paging enhancement feature A within that range can be used; when the first indication information is "IE2", paging enhancement feature B within that range can be used.

[0171] a2: Regarding the second indication information carried in the dedicated message, indicating whether paging enhancement features are used:

[0172] The second indication information, when indicating whether a terminal device can use a certain paging enhancement feature, can be implemented by using a "yes" or "no" flag corresponding to that paging enhancement feature.

[0173] If the second indication message carries a "yes" flag, it indicates that the terminal device can use paging enhancement features; if it carries a "no" flag, it indicates that the terminal device cannot use paging enhancement features. Specifically, this indication information can be carried in specific bits of the dedicated message; if the specific bit is "0", it indicates that paging enhancement features cannot be used; if the byte is "1", it indicates that paging enhancement features can be used. Furthermore, there can be one or more paging enhancement features, so the second indication information can carry flags indicating whether multiple paging enhancement features can be used. For example, if there are four paging enhancement features, then the indication information can have four bits dedicated to carrying flags indicating whether the four paging enhancement features can be used. If the four paging enhancement features are A, B, C, and D, and the indication information carried in the dedicated message is "0011", where "0" indicates no and "1" indicates yes, then it indicates that paging enhancement features C and D can be used, but paging enhancement features A and B cannot be used.

[0174] a3: This refers to situations where the first and second indications are combined to indicate whether paging enhancement features can be used.

[0175] The first indication information can be, for example, as described in a1 above, an identification identifier used to distinguish different paging enhancement features. The second indication information can be, for example, as described in a2 above, specifically used to indicate whether the paging enhancement feature corresponding to the identification identifier is usable. For example, for a certain paging enhancement feature X, its corresponding first indication information (i.e., the identification identifier of X) is "IE", the second indication information indicating that the paging enhancement feature X is usable is "1", and the second indication information indicating that the paging enhancement feature X is not usable is "0". Then, when the special message carries "IE0", it indicates that the paging enhancement feature X is not usable; when the special message carries "IE1", it indicates that the paging enhancement feature X is usable.

[0176] In another possible implementation, the indication information (first indication information and / or second indication information) may, for example, indicate at least one of the following:

[0177] b1: Instructs the terminal device to use paging enhancement features when receiving paging messages.

[0178] b2: Indicates that the network-side device can obtain the paging enhancement feature of the terminal device.

[0179] b3: Indicates the type of paging enhancement feature used by the terminal device when receiving paging messages.

[0180] b4: Indicates that the network-side device can obtain the paging enhancement feature type of the terminal device.

[0181] b5: Indicates the version information supported by the network-side device; the version information is used to determine the paging enhancement features that the terminal device can use.

[0182] Here, different versions of the communication protocol can introduce different paging features; if the indication information indicates the version information supported by the network-side device, it can be determined whether the terminal device can use the paging enhancement feature when receiving a paging message based on the version information.

[0183] Through the above process, the network-side device can synchronously paging the terminal device.

[0184] B1: For situations where terminal devices synchronize their wireless paging capabilities with network-side devices, the following method can be used: report the terminal device's wireless paging capability information to the network-side device.

[0185] In practice, network-side devices may include access network devices and core network devices. Terminal devices can report wireless paging capability information to the access network or to the core network devices.

[0186] Specifically, when a terminal device reports its wireless paging capability information to a core network device, it can do so, for example, through a non-access stratum (NAS) message.

[0187] During this process, after receiving the radio paging capability information reported by the terminal device, the core network device stores it and can transparently forward the radio paging capability information to the access network device.

[0188] When a terminal device reports its wireless paging capability information to an access network device, it can do so, for example, through a Radio Resource Control (RRC) message.

[0189] During this process, the access network device receiving the reported wireless paging capability information can store it after receiving the wireless paging capability information reported by the terminal device, and can transparently forward the wireless paging capability information to the core network device.

[0190] Furthermore, in this embodiment, the function of the terminal device reporting its wireless paging capability information to the network side is independent of the conventional "UE Radio Capability" or wireless access capability of the terminal device. "UE Radio Capability" refers to the wireless capability of the user equipment (terminal device), that is, the ability of the mobile terminal to communicate with the access network device via wireless signals, including supported wireless access technologies, frequency bands, carrier aggregation, etc. In this embodiment, the purpose of the terminal device reporting its wireless paging capability information to the network side is to ensure that the paging characteristics used by the terminal device and the access network device are synchronized during the paging process, thereby avoiding paging failures caused by asynchrony between the paging characteristics used by the terminal device and the access network device.

[0191] In another embodiment, when a terminal device reports its wireless paging capability information to a network-side device, it can do so via a container.

[0192] This container can include multiple sub-containers, each corresponding to a different Radio Access Technology (RAT). For example, NR RAT (New Radio RAT), i.e., 5G, corresponds to one container 1; Evolved Universal Terrestrial Radio Access (EUTRA), i.e., 4Geutra, corresponds to one sub-container 2; and the subsequent sixth-generation communication system, 6G, corresponds to one container 3. These containers are all included in container X, which is dedicated to synchronizing the terminal device's wireless paging capability with the network-side equipment.

[0193] In this way, the function of synchronizing wireless paging capability is isolated from other functions of the communication network by using a container, thereby reducing interference with other functions of the communication network.

[0194] In another embodiment, the paging capability information can be carried on an octet string type. Specifically, an octet is a data type. By carrying the paging capability information in an octet string type, when a network-side device receives an IE (information element) of an OCTETSTRING for a certain field, it can directly and transparently forward the received field or IE to another network-side device.

[0195] Through the above process, the terminal device is able to synchronously paging network-side devices.

[0196] See Figure 2 The diagram shows a flowchart of another paging method provided in this embodiment of the present disclosure. This method is applied to a network-side device and includes step S201, wherein:

[0197] S201: Synchronize wireless paging capability with terminal equipment; wireless paging capability is used to indicate the paging features that the terminal equipment can use.

[0198] In the paging method provided in this embodiment, the network-side device synchronizes its wireless paging capability with the terminal device; this wireless paging capability is used to indicate the paging features that the terminal device can use. Thus, when the network-side device paging the terminal device, it paging the terminal device according to these paging features, avoiding paging failures caused by inconsistencies between the paging features used by the network-side device when paging the terminal device and those used by the terminal device when listening for paging.

[0199] The paging method described above will be explained in detail below through other embodiments.

[0200] In practice, after the network-side device synchronizes its wireless paging capability with the terminal device, it can save the information related to the wireless paging capability. When it is necessary to paging the terminal device, it can determine the specific paging characteristics based on its own paging characteristics and the wireless paging capability synchronized with the terminal device, determine the specific paging method to be used by the paging terminal device, and then paging the terminal device.

[0201] A2: For the case where the network-side device synchronizes wireless paging capability to the terminal device: a dedicated message is sent to the terminal device; the dedicated message indicates whether the terminal device can use paging enhancement features by whether it carries first indication information and / or second indication information.

[0202] For details on specific messages and instruction messages, please refer to the above embodiments, which will not be repeated here.

[0203] The instruction information (first instruction information and / or second instruction information) indicates that the terminal device is capable of using paging enhancement features; the instruction information indicates at least one of the following:

[0204] Instructs terminal devices to use paging enhancement features when receiving paging messages;

[0205] This indicates that network-side devices can obtain the paging enhancement features of terminal devices;

[0206] Indicates the type of paging enhancement feature used by the terminal device when receiving paging messages;

[0207] Indicates that the network-side equipment can obtain the paging enhancement feature type of the terminal device;

[0208] Indicates the version information supported by network-side devices.

[0209] Furthermore, if the dedicated message sent by the network-side device to the terminal device does not include the aforementioned indication information, the terminal device cannot use the paging enhancement feature when receiving paging messages.

[0210] In another embodiment, when the network-side device that synchronizes wireless paging capability to the terminal device is an access network device, the access network device will also send the terminal device's wireless paging capability information to the core network device.

[0211] Specifically, when the access network device sends the terminal device's wireless paging capability information to the core network device, it may do so under any of the following specific circumstances: c1 to c4

[0212] c1: When the terminal device context is released, send the terminal device's radio paging capability information to the core network device.

[0213] Terminal Equipment Context (TEF) refers to a series of information maintained by access network equipment (such as base stations) to manage and serve terminal devices (such as mobile phones and tablets). This information includes the terminal device's identifier, connection status, radio resources used, security parameters, and quality of service (QoS) configuration. The access network equipment releases the TEF when the normal connection between the base station and the terminal device ends, when the terminal device moves to another area, or when network resource management requirements, abnormal situations, or faults occur.

[0214] When the terminal device context is released, the access network device will proactively send the terminal device's radio paging capability information to the core network device.

[0215] When an access network device actively sends the wireless paging capability information of a terminal device to a core network device, it may carry the wireless paging capability information in a signaling message.

[0216] After receiving the wireless paging capability information of the terminal device from the access network device, the core network device stores it; subsequently, the core network device can send the obtained wireless paging capability information of the terminal device to the access network device, thereby assisting the access network device in paging the terminal device.

[0217] Alternatively, when releasing the terminal device context, the access network device may request the terminal device's radio paging capability information from the core network device; if the radio paging capability information returned by the core network device does not match the terminal device's radio paging capability information stored in the access network device, the access network device may send the terminal device's radio paging capability information to the core network device.

[0218] This ensures the consistency between the wireless paging capability information of the terminal devices stored in the core network equipment and the wireless paging capability information stored in the access network equipment, thereby guaranteeing continuous communication and preventing subsequent paging failures.

[0219] For example, under certain circumstances, the access network device NG-RAN and the core network device AMF may exchange UE radio capability for paging information:

[0220] NG-RAN nodes can provide UE radio capability for paging to the AMF if the UE context is released and either of the following two conditions (1) or (2) applies:

[0221] (1): NG-RAN nodes proactively provide UE radio capability for paging to AMF;

[0222] (2): The NG-RAN node requests the AMF to provide UE radio capability for paging; if the NG-RAN finds that the UE radio capability for paging provided by the AMF is not complete, that is, it does not match the UE radio capability for paging stored in the NG-RAN, the NG-RAN node provides the UE radio capability for paging to the AMF.

[0223] c2: When a terminal device context is established, send the terminal device's radio paging capability information to the core network device.

[0224] During this process, the access network device obtains the terminal device's radio paging capability information stored by the core network device. If it finds that the radio paging capability information provided by the core network device does not match the terminal device's radio paging capability information obtained by the access network device (for example, the access network device can obtain the terminal device's radio paging capability information based on the UE's UE radio capability), it sends the terminal device's radio paging capability information to the core network device.

[0225] For example, when establishing a terminal device context, if the access network device finds that the UE radiocapability for paging provided by the AMF is incomplete, it will proactively provide the UE radio capability for paging to the AMF.

[0226] This ensures the consistency between the wireless paging capability information of the terminal devices stored in the core network equipment and the wireless paging capability information stored in the access network equipment, thereby guaranteeing continuous communication and preventing subsequent paging failures.

[0227] c3: In the event of a path switch in a terminal device, send the terminal device's wireless paging capability information to the core network equipment.

[0228] Specifically, path switching typically refers to the process by which a terminal device switches from its current communication path to another during network connection. Specifically, when a terminal device moves, it may move further away from the access network equipment it is currently serving, resulting in a weakened received signal. To ensure communication quality, the terminal device will switch to an access network equipment with a stronger signal. Alternatively, when the environment in which the terminal device is located experiences significant interference, leading to an increased bit error rate and deteriorated communication quality, path switching will also be triggered to find a better signal. Furthermore, the network side will proactively guide the terminal device to switch paths based on the load conditions of each path, such as bandwidth utilization and congestion levels, switching the terminal from a high-load path to a low-load path to achieve balanced utilization of network resources.

[0229] When a path switch occurs, the access network device sends the terminal device's wireless paging capability information to the core network device.

[0230] In another embodiment of this disclosure, the access network device may also transmit the wireless paging capability information of the terminal device to other access network devices.

[0231] c4: During UE Information Transfer, send the terminal device's radio paging capability information to the core network equipment.

[0232] Specifically, the access network device may proactively send the terminal device's wireless paging capability information to the core network device when it discovers a mismatch between the wireless paging capability information provided by the core network device and the wireless paging capability information of the terminal device obtained within the access network device (for example, the access network device can obtain the terminal device's wireless paging capability information based on the UE's radiocapability); or

[0233] When the access network device determines that it can obtain the wireless paging enhancement capability of the terminal, it actively sends the wireless paging capability information of the terminal device to the core network device.

[0234] B2: For situations where terminal devices synchronize wireless paging capabilities with network-side devices:

[0235] The network-side equipment receives the wireless paging capability information of the terminal equipment reported by the terminal equipment.

[0236] Here, the specific process of the terminal device reporting its wireless paging capability information to the network side device can be found in the above embodiment B1, and will not be repeated here.

[0237] Specifically, in the case where network-side equipment includes core network equipment, the core network equipment can, for example, receive wireless paging capability information of the terminal equipment reported to the core network equipment by the terminal equipment through non-access stratum (NAS) messages.

[0238] In another embodiment, when the terminal device reports wireless paging capability information to the core network device, the core network device can also transparently forward the received wireless paging capability information to the access network device, so that the wireless paging capability information stored in the access network device and the terminal device are kept synchronized, avoiding paging failures caused by the different paging characteristics used by the access network device and the terminal device during the paging process.

[0239] In another embodiment, the core network device may also transparently forward radio paging capabilities to the access network device in the form of a container. Optionally, the radio paging capability information is carried in an octet string type.

[0240] In cases where network-side devices include access network devices, the access network devices can, for example, receive wireless paging capability information of the terminal devices reported to the access network devices by the terminal devices via Radio Resource Control (RRC) messages.

[0241] Optionally, the access network device can also transparently forward the wireless paging capability information reported by the terminal device to the core network device.

[0242] In another embodiment, the access network device can also transparently forward the terminal device's wireless paging capability information to other access network devices in the form of a container.

[0243] The above method enables the synchronization of wireless paging capabilities between network-side devices and terminal devices.

[0244] The synchronization process of wireless paging capability is illustrated below through several examples:

[0245] Example 1: The UE determines whether a certain paging enhancement feature can be used based on the indication information carried in the dedicated message by the network-side device.

[0246] The network side sends an indication message to the UE via a dedicated RRC message. This indication message indicates that the UE can "use enhanced features when receiving paging" or that the network-side device can obtain the UE's paging enhancement features. This indication message can be a 1-bit indication, used to indicate that the UE can use paging enhancement features after R15 when receiving paging (here, the specific paging feature type does not need to be distinguished).

[0247] Alternatively, the network side may instruct the UE on the specific paging enhancement features that can be used or the UE paging enhancement features that can be obtained. For example, the network side may instruct the UE to use PEI or instruct the network side to obtain the UE's PEI capabilities.

[0248] Optionally, the network side can send indication information to the UE via RRC reconfiguration messages. For example, if the base station discovers that the UE's radio capability for paging obtained from the core network equipment does not include higher-version paging enhancement features, the base station can send an RRC reconfiguration message to the UE, instructing the UE to "use enhancement features when receiving paging" or instructing the network side to obtain the UE's paging enhancement features; or instructing the UE to "use PEI when receiving paging" or "use LP-WUS when receiving paging," or instructing the network side to obtain the UE's PEI capability or LP-WUS capability.

[0249] Optionally, the network side can send an indication to the UE via an RRC release message. For example, when the base station releases the UE, it determines what the UE's radio capability for paging includes. If it includes paging enhancement features, the base station can instruct the UE to "use enhancement features when receiving paging" or instruct the network side to obtain the UE's paging enhancement features when releasing the UE. Alternatively, if the UE supports LP-WUS features, the network side can instruct the UE to "use LP-WUS when receiving paging" or instruct the network side to obtain the UE's LP-WUS capability.

[0250] Optionally, the base station needs to send UE radio capability forpaging, including higher versions of paging enhancement features, to the core network.

[0251] Based on the indication, the UE determines that it can "use relevant features when receiving paging". If the UE does not receive the indication information, it cannot use paging-related enhancement features when receiving paging. (Note: When determining whether a UE can use a certain paging feature, it still needs to consider the paging features supported by the UE and the paging features supported by the network. For example, whether the UE can use PEI depends not only on whether the UE receives the aforementioned indication information, but also on whether the UE can receive PEI in the current cell and whether the current cell supports PEI features (e.g., whether the cell broadcasts PEI parameters).

[0252] For example, if the UE receives an indication in the RRCrease message that it can "use enhanced features when receiving paging," then the UE can use paging enhancement features when receiving paging. Specifically, paging enhancement features can be a series of paging enhancement features expanded from version R17 onwards in the UE radio capability for paging message.

[0253] For example, if the UE receives an indication in the RRRCRelease message indicating that the network can obtain the UE's PEI capability, then the UE can use the PEI feature when receiving a paging message.

[0254] Optionally, the UE will determine whether it can “use relevant features when receiving paging” based on the indication information in the most recently received RRC release message.

[0255] Optionally, after the UE re-enters the RRC connected state, it will determine whether it can "use related features when receiving paging" based on whether it received an indication message before entering the idle / inactive state. If it does not receive the relevant indication message when re-entering the RRC connected state and then the idle / inactive state, the UE will consider that no indication message was received and will not be able to use paging-related enhancement features when receiving paging.

[0256] Optionally, the indication information received by the UE will remain valid until the UE registers, powers off, or exchanges UE capabilities with the base station (corresponding to the UE capability transfer process in 5G). For example, when the UE receives an RRC reconfiguration message, this message includes the indication that "LP-WUS features can be used when receiving paging," which is used by the UE to determine whether LP-WUS features can be used. The UE stores this indication information, and it remains valid regardless of how many RRC state transitions the UE undergoes (e.g., from connected to idle, and then from idle to connected, etc.), used by the UE to determine whether LP-WUS features can be used. This indication information only becomes invalid when the UE registers, powers off, or exchanges UE capabilities with the base station.

[0257] By using the above methods, it can be ensured that the paging characteristics used by the terminal and the network side are consistent.

[0258] Example 2: The UE determines whether a certain paging enhancement feature can be used based on the version information sent by the network-side device through a dedicated message.

[0259] The network side sends an indication message to the UE via a dedicated RRC message, which indicates the version information currently supported by the network. Optionally, the network side can send the indication message to the UE via an RR reconfiguration message, or via an RRC release message. For example, when the base station releases the UE, it determines the highest version information included in the UE's radio capability for paging; therefore, the base station can indicate the version information currently supported by the network when releasing the UE.

[0260] The UE determines whether to "use relevant features when receiving paging" based on the indication. If the UE does not receive the indication, it cannot use paging-related enhancement features when receiving paging. For example, if the UE receives an indication in the RRRCRelease message indicating the version information currently supported by the network, then the UE can use paging features extended to the version corresponding to that version when receiving paging.

[0261] By using the above methods, it can be ensured that the paging characteristics used by the terminal and the network side are consistent.

[0262] Example 3: Interaction between NG-RAN side node and AMF: UE radio capability for paging.

[0263] NG-RAN side nodes can provide UE radio capability forpaging to the AMF when releasing the UE context.

[0264] Furthermore, when the NG-RAN side node sends the indication information in Embodiment 1 or 2 to the UE, the NG-RAN side node provides the AMF with UE radio capability for paging when releasing the UE context or when deciding to send an RRC reconfiguration message carrying the indication information to the UE. This can be done, for example, by providing the UE radio capability for paging to the AMF through the UE CONTEXT RELEASE COMPLETE message or through the UE Information Transfer procedure.

[0265] Alternatively, the NG-RAN side node can provide UE radio capability for paging to the AMF via a request method. The NG-RAN side node first sends a request to the AMF (e.g., through a UE CONTEXT RELEASE REQUEST message requesting the AMF to provide UE radio capability for paging), and the AMF provides the UE radio capability for paging in a CONTEXT RELEASE COMMAND message. If the NG-RAN finds that the UE radio capability for paging provided by the AMF is incomplete, it can optionally provide the UE radio capability for paging to the AMF via a UE CONTEXTRELEASE COMPLETE message.

[0266] NG-RAN side nodes can proactively provide UE radio capability for paging to the AMF when they find that the UE radio capability for paging provided by the AMF is incomplete.

[0267] Specifically, when the AMF provides the entire initial UE context to the NG-RAN side node, it provides UE radio capability for paging. This is an existing procedure; for example, the AMF provides UE radio capability for paging through the INITIAL CONTEXT SETUP REQUEST message. If the NG-RAN side node finds that the UE radio capability for paging provided by the AMF is incomplete, such as not including the capabilities corresponding to the paging enhancement features starting from Release 17, then the NG-RAN side node proactively provides UE radio capability for paging to the AMF.

[0268] Optionally, NG-RAN side nodes can transmit UE radio capability for paging. If an NG-RAN side node finds that the UE radio capability for paging provided by the AMF is incomplete, such as not including capabilities corresponding to paging enhancement features starting from Release 17, the NG-RAN side node will proactively provide the UE radio capability for paging to the AMF. Specifically, this can be done through a PATH SWITCH REQUEST.

[0269] The above methods ensure that the AMF can obtain complete UE paging capabilities in a timely manner, achieving consistency between the paging characteristics used by the terminal and the network side during CN paging.

[0270] Example 4: UE radio capability for paging is transmitted at the NAS layer:

[0271] The UE reports its radio paging capabilities via NAS messages. Specifically, the UE radio paging capability is represented by a container. Further, this container can include multiple sub-containers, each corresponding to a different RAT. For example, the NR RAT corresponds to container 1, the Eutra RAT to sub-container 2, and the subsequent 6G system to container 3. These containers are all included in container X, which is dedicated to transmitting various UE radio paging capabilities. Here, UE radio paging capabilities refer to the UE capability information required during the paging process, such as which bands the UE supports paging on, and which bands the UE supports LP-WUS on.

[0272] Optionally, wireless paging capability information is carried within an octet string type. Furthermore, NR RAT can be placed within an octet string type, eutra within an octet string type, and so on.

[0273] The AMF stores the received UE radio paging capabilities. The AMF transparently forwards the UE's radio information capabilities to the RAN node. Specifically, this is done through a container sent to the RAN node. This can occur during the UE's initial context establishment process or in a paging message. Based on the received UE radio paging capabilities, the RAN node triggers a paging process relevant to that UE.

[0274] The RAN node receives UE radio paging capability from the AMF.

[0275] RAN nodes also need to transparently forward UE radio paging capabilities. Specifically, this can be done by: carrying it in the Handover Preparation Information; or carrying it in the RAN paging message, whereby the RAN node triggers a paging process for that UE based on the received UE radio paging capability.

[0276] This method ensures lossless transmission of UE wireless paging capabilities between RAN-side nodes and core network nodes, thereby achieving consistency in the paging characteristics used by the terminal and network side during paging in subsequent version evolutions.

[0277] Example 5: UE radio capability for paging is passed through a separate container at the RRC layer:

[0278] The UE reports its radio paging information capability via RRC messages. In this case, the UE radio paging information capability is either a container independent of the UE Radio Capability, or a container within the UE Radio Capability. Specifically, in this embodiment, the container refers to another container independent of the containers within the UE Radio Capability or radio access capability.

[0279] Specifically, the UE radio paging capability is represented by a container. Further, this container can include multiple sub-containers, each corresponding to a different RAT. For example, the NR RAT corresponds to container 1, Eutra corresponds to sub-container 2, and subsequent 6G systems correspond to container 3. These containers are all included in container X, which is dedicated to transmitting various UE radio paging capabilities. Note: UE radio paging capabilities refer to the UE capability information required during the paging process, such as which bands the UE supports paging on, and which bands the UE supports LP-WUS on.

[0280] Optionally, the UE radio paging capability information is carried within an octet string type. Furthermore, the NR RAT can be placed within an octet string type, and the eutra can be placed within an octet string type, etc.

[0281] The RAN node forwards the radio paging capability reported by the UE to the core network node. RAN nodes transmit UE radio paging capabilities to each other in the form of containers.

[0282] The AMF stores the received UE radio paging capabilities. The AMF then transmits the UE radio information capabilities to the RAN node.

[0283] This method ensures lossless transmission of UE wireless paging capabilities between RAN-side nodes and core network nodes, thereby achieving consistency in the paging characteristics used by the terminal and network side during paging in subsequent version evolutions.
