Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a wireless communication method, terminal device, and network device. Background Technology

[0002] In order to notify terminal devices that are in the Radio Resource Control (RRC) inactive state (RRC_INACTIVE) to enter the connected state, New Radio (NR) introduced an access network paging mechanism.

[0003] The paging process initiated by the access network includes: the access network releasing the terminal device from a connected state to an inactive state, while still maintaining the terminal device's Access Stratum (AS) context. During this process, the access network configures a paging area configuration for the terminal device. This configuration may include any of the following: a list of Closed Access Group Identifiers (CGIs), a list of Tracking Area Identifiers (TAIs), or a list of access network area codes. Both the access network and the terminal device maintain this paging area configuration. If the configuration of the terminal device's camped cell does not match any of the configurations in the paging area configuration provided by the access network, the terminal device triggers a RAN Notification Area Update (RNAU), allowing the access network to configure new paging area configuration information for the terminal device. Otherwise, subsequent paging processes initiated by the access network will fail.

[0004] However, in non-terrestrial network (NTN) systems, due to the high-speed movement of satellites relative to the ground, the cell where terminal devices reside changes frequently. If the RNAU triggering mechanism described above continues to be used, it will lead to excessive power consumption of the terminal devices. Summary of the Invention

[0014] Specifically, the network device includes a functional module for performing the methods described in the third aspect or its various implementations.

The memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to perform the methods described in the first aspect or its various implementations.

[0017] A ninth aspect provides a network device including a processor and a memory. The memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to perform the methods of the third aspect or its implementations described above.

[0018] In a tenth aspect, an apparatus is provided for implementing the method in any one of the first to third aspects or their respective implementations.

[0019] Specifically, the device includes a processor for calling and running a computer program from memory, causing a device equipped with the device to perform the method as described in any of the first to third aspects or their respective implementations.

[0020] Eleventhly, a computer-readable storage medium is provided for storing a computer program that causes a computer to perform the methods of any one of the first to third aspects or their respective implementations.

[0021] In a twelfth aspect, a computer program product is provided, including computer program instructions that cause a computer to perform the methods of any one of the first to third aspects or their respective implementations.

[0022] In a thirteenth aspect, a computer program is provided that, when run on a computer, causes the computer to perform the methods of any one of the first to third aspects or their respective implementations.

[0023] With the above technical solution, the terminal device will not trigger RNAU due to any mismatch between the configuration of the corresponding cell where the terminal device is camped and any of the paging area configuration information configured for the terminal device by the access network. Instead, the terminal device performs RNAU based on the aforementioned first configuration information and the terminal device's motion information. Compared with existing RNAU triggering methods, this method does not cause frequent RNAU triggering, thereby reducing the power consumption of the terminal device. Attached Figure Description

[0040] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0041] Network devices can be devices used to communicate with mobile devices. Network devices can be access points (APs) in WLANs, base stations (BTSs) in GSM or CDMA, base stations (NodeBs, NBs) in WCDMA, evolved Node Bs (eNBs or eNodeBs) in LTE, relay stations or access points, or in-vehicle devices, wearable devices, and network devices (gNBs) in NR networks, or network devices in future PLMN networks, etc.

For example, the satellite can be a low Earth orbit (LEO) satellite, a medium Earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, or a highly elliptical orbit (HEO) satellite. Optionally, network equipment can also be a base station located on land, water, or other similar locations.

[0043] In this embodiment, the network device can provide services to a cell. The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0044] The following is combined Figure 1A-Figure 1B The architecture of the communication system in this application will be described.

[0045] Figure 1A This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. Please refer to [link / reference]. Figure 1A This includes terminal device 1101 and satellite 1102, which can communicate wirelessly. The network formed between terminal device 1101 and satellite 1102 can also be called an NTN. Figure 1AIn the architecture of the communication system shown, satellite 1102 can function as a base station, and terminal device 1101 and satellite 1102 can communicate directly. Satellite 1102 is referred to as a regenerating satellite. Within this system architecture, satellite 1102 can be referred to as a network device. Optionally, the communication system may include multiple network devices 1102, and the coverage area of ​​each network device 1102 may include other numbers of terminal devices; this embodiment does not limit this.

[0048] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" is used to describe the relationships between related objects, indicating that there are three possible relationships between them. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the relationship between related objects is "or".

[0049] In the description of the embodiments of this application, the term "correspondence" may indicate that there is a direct or indirect correspondence between two things, or that there is an association between two things, or that there is a relationship of instruction and being instructed, configuration and being configured, etc.

[0050] To clearly illustrate the ideas behind the embodiments of this application, the relevant technical content of the embodiments of this application will first be briefly described. The embodiments of this application include at least some of the following contents.

[0051] The main application scenarios for 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low-Latency Communication (URLLC), and Massive Machine-Type Communication (mMTC). eMBB still aims to provide users with multimedia content, services, and data, and its demand is growing rapidly. Because eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, its capabilities and needs vary considerably, so generalizations cannot be made; a detailed analysis based on the specific deployment scenario is necessary. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance. Typical characteristics of mMTC include: high connection density, small data volume, latency-insensitive services, low module cost, and long module lifespan.

[0052] The inactive state is a new RRC state introduced by the NR system to reduce the latency for terminal devices to enter the connected state. The access network still maintains the AS context of the terminal device. From the perspective of the core network, the terminal device is still in the connected state because the NG interface connection at the terminal device level between the core network and the access network is still maintained. Only the Uu interface connection between the access network and the terminal device is released. Compared with the idle state, which requires the establishment of complete Un and NG interface connections, the terminal device in the inactive state only needs to establish a Uu interface connection to enter the connected state, thereby reducing the latency for the terminal device to enter the connected state.

[0053] To notify inactive terminal devices to enter connected mode, NR introduces an access network paging mechanism. Whenever the core network needs to send data to a terminal device that is inactive, the access network triggers an access network paging process to notify the terminal device to enter connected mode. The paging area configuration information (i.e., access network paging area configuration) is configured by the access network for the terminal device when it is released to inactive mode. This paging area configuration information is maintained on both the access network and terminal device sides and can include any of the following configuration formats: CGI list information, TAI list information, or access network area code list information. Each CGI is identified by Public Land Mobile Network (PLMN) ID + Cell ID; each TAI is identified by PLMN ID + TAC ID; and each access network area code is identified by PLMN ID + TAC ID + RAN Area Code (RANAC) ID.

[0054] The reason why the access network maintains the paging area configuration information is that it needs to use this configuration to send access network paging messages in order to find the paging terminal. The terminal device also needs to maintain this configuration to ensure consistency between the access network and the terminal device. If the corresponding configuration of the terminal device's camped cell does not match any of the configurations in the paging area configuration information configured by the access network for the terminal device, the terminal device will trigger RNAU, so that the access network can configure new paging area configuration information for the terminal device; otherwise, the subsequent paging process sent by the access network will fail.

[0055] As mentioned above, in the NTN system, due to the high speed of the satellite relative to the ground, the cell where the terminal device is stationed will change frequently. If the RNAU triggering mechanism mentioned above is continued, it will lead to excessive power consumption of the terminal device.

[0056] The technical solution of this application will be described in detail below:

[0057] Example 1

[0058] Figure 2 An interactive flowchart of a wireless communication method provided in an embodiment of this application is shown below. Figure 2 As shown, the method includes:

[0059] S210: The network device sends the first configuration information to the terminal device.

[0060] S220: The terminal device performs RNAU based on the first configuration information and the motion information of the terminal device.

[0061] The first configuration information includes: configuration information for periodically triggered RNAUs, and / or, configuration information for event-triggered RNAUs. The configuration information for event-triggered RNAUs includes: displacement-related information of the terminal device, and / or, location-related information of the terminal device.

[0062] Optionally, the first configuration information may be carried in a system broadcast message or a dedicated signaling message, but is not limited to these.

[0063] Optionally, dedicated signaling may be connection release signaling, but is not limited to this.

[0064] Optionally, the configuration information for periodically triggering RNAU includes: the default execution cycle of RNAU, the displacement evaluation cycle of the terminal device, and at least one displacement evaluation threshold of the terminal device.

[0065] It should be understood that the RNAU cycle refers to how often the terminal device executes the RNAU.

[0066] Optionally, the configuration information for periodically triggering RNAU may also include at least one adjustment parameter for the default execution cycle of RNAU.

[0067] It should be understood that the displacement assessment cycle of terminal equipment refers to the cycle used to assess the displacement of terminal equipment.

[0068] It should be understood that at least one displacement evaluation threshold constitutes multiple displacement evaluation threshold ranges, and each displacement evaluation threshold range corresponds to an adjustment parameter of the aforementioned default execution cycle.

[0069] Optionally, the adjustment parameter for the default execution cycle is used to adjust the default execution cycle. The terminal device can adjust the default execution cycle according to the adjustment parameter in at least one of the following ways, but is not limited to:

[0070] Add adjustment parameters to the default execution cycle; the adjustment parameters can take positive or negative values.

[0071] Multiply the default execution cycle by the adjustment parameters.

[0072] It should be understood that this application does not impose any restrictions on the aforementioned adjustment parameters.

[0073] Optionally, the displacement-related information of the aforementioned terminal device includes at least one displacement threshold, but is not limited thereto.

[0074] Optionally, the location-related information of the aforementioned terminal device includes: location reference information; or, the location-related information of the aforementioned terminal device includes at least one of the following: at least one CGI, at least one TAC, and at least one RANAC.

[0075] It should be understood that, in this application, each location information of the terminal device is represented using latitude and longitude information or spatial coordinates.

[0076] Optionally, the motion information of the terminal device is the displacement of the terminal device within the displacement evaluation period, or the motion information of the terminal device is the current position information of the terminal device.

[0077] In summary, in this application, the terminal device performs RNAU based on the aforementioned first configuration information and the motion information of the terminal device. Compared with existing RNAU triggering methods, this method does not cause frequent RNAU triggering, thereby reducing the power consumption of the terminal device.

[0078] Example 2

[0079] As described above, the terminal device can perform RNAU based on the configuration information for periodically triggering RNAU and the motion information of the terminal device. This will be explained in detail below:

[0080] Optionally, the motion information of the terminal device is the displacement of the terminal device within the displacement evaluation cycle. The terminal device determines the displacement threshold range corresponding to its displacement within the displacement evaluation cycle based on at least one displacement evaluation threshold, determines a first adjustment parameter from at least one adjustment parameter of the default execution cycle based on the displacement threshold range, and finally performs RNAU using the default execution cycle, or adjusts the default execution cycle according to the first adjustment parameter to perform RNAU periodically.

[0081] It should be understood that, assuming the terminal device adjusts the default execution cycle by multiplying it by an adjustment parameter, then when the terminal device determines the first adjustment parameter to be 1, it means there is no need to adjust the default execution cycle; therefore, the terminal device uses the default execution cycle for RNAU. Alternatively, assuming the terminal device adjusts the default execution cycle by adding an adjustment parameter to it, then when the terminal device determines the first adjustment parameter to be 0, it means there is no need to adjust the default execution cycle; therefore, the terminal device uses the default execution cycle for RNAU.

[0082] Optionally, the larger the displacement of the terminal device within the displacement assessment period, the smaller the adjusted period of RNAU; conversely, the smaller the displacement of the terminal device within the displacement assessment period, the larger the adjusted period of RNAU, but this is not limited to these possibilities.

[0083] Example 1, assume that the terminal device is configured with two displacement evaluation thresholds, namely S1 and S2, where S1 < S2. Therefore, these two displacement evaluation thresholds form three displacement evaluation threshold ranges, which are less than or equal to S1, less than S1 and greater than or equal to S2, and greater than S2. Assume that these three displacement evaluation threshold ranges are called displacement evaluation threshold range 1, displacement evaluation threshold range 2, and displacement evaluation threshold range 3. Assume that the terminal device multiplies the default execution period by an adjustment parameter, and the adjustment parameters corresponding to displacement evaluation threshold range 1, displacement evaluation threshold range 2, and displacement evaluation threshold range 3 are 1, 2, and 3 respectively. Then, if the terminal device determines that the displacement evaluation threshold range to which the displacement amount within the displacement evaluation period belongs is displacement evaluation threshold range 1, it means that the terminal device is in a normal state or a regular state. At this time, the corresponding adjustment parameter is 1, that is, the terminal device performs RNAU using the default execution period. If the terminal device determines that the displacement evaluation threshold range to which the displacement amount within the displacement evaluation period belongs is displacement evaluation threshold range 2, it means that the terminal device is in a medium-speed state. At this time, the corresponding adjustment parameter is 2, that is, the terminal device performs RNAU using T / 2. T represents the default execution period. If the terminal device determines that the displacement evaluation threshold range to which the displacement amount within the displacement evaluation period belongs is displacement evaluation threshold range 3, it means that the terminal device is in a high-speed state. At this time, the corresponding adjustment parameter is 3, that is, the terminal device performs RNAU using T / 3.

[0084] Example 2. Assume that the terminal device is configured with two displacement evaluation thresholds, namely S1 and S2, where S1 < S2. Therefore, these two displacement evaluation thresholds form three displacement evaluation threshold ranges, which are less than or equal to S1, less than S1 and greater than or equal to S2, and greater than S2 respectively. Assume that these three displacement evaluation threshold ranges are called displacement evaluation threshold range 1, displacement evaluation threshold range 2, and displacement evaluation threshold range 3. Assume that the terminal device adds an adjustment parameter to the default execution period, and the adjustment parameters corresponding to displacement evaluation threshold range 1, displacement evaluation threshold range 2, and displacement evaluation threshold range 3 are 0, -1, and -2 respectively. Then, if the terminal device determines that the displacement amount within the displacement evaluation period belongs to displacement evaluation threshold range 1, it means that the terminal device is in a normal state or a regular state. At this time, the corresponding adjustment parameter is 0, that is, the terminal device uses the default execution period for RNAU. If the terminal device determines that the displacement amount within the displacement evaluation period belongs to displacement evaluation threshold range 2, it means that the terminal device is in a medium-speed state. At this time, the corresponding adjustment parameter is -1, that is, the terminal device uses T - 1 for RNAU. If the terminal device determines that the displacement amount within the displacement evaluation period belongs to displacement evaluation threshold range 3, it means that the terminal device is in a high-speed state. At this time, the corresponding adjustment parameter is -2, that is, the terminal device uses T - 2 for RNAU.

[0085] It should be understood that the method of dividing the displacement evaluation threshold range according to the displacement evaluation threshold in Example 1 and Example 2 is not limited to the above division method. For example: the three displacement evaluation threshold ranges are less than S1, greater than or equal to S1 and greater than or equal to S2, and greater than S2 respectively. Or, the three displacement evaluation threshold ranges are less than S1, greater than or equal to S1 and greater than S2, and greater than or equal to S2 respectively.

[0086] In summary, in this application, the terminal device performs RNAU according to the configuration information for periodically triggering RNAU and the motion information of the terminal device. This method, compared with the existing RNAU triggering method, will not cause frequent triggering of RNAU, thereby reducing the power consumption of the terminal device.

[0087] Embodiment 3

[0088] As described above, the terminal device can perform RNAU according to the configuration information for event-triggered RNAU and the motion information of the terminal device. The following is a detailed description of this:

[0089] Optionally, the configuration information for event-triggered RNAU includes: location-related information of the terminal device. Location-related information includes: location reference point information. The motion information of the terminal device is its current location information. Based on this, the terminal device determines a first relative distance relative to the location reference point information, using both the current location information and the location reference point information.

[0090] If the first relative distance is greater than or equal to the first displacement threshold, the terminal device performs RNAU; or,

[0091] If the first relative distance is less than or equal to the second displacement threshold, the terminal device performs RNAU; or,

[0092] If the first relative distance is greater than the second displacement threshold and less than the first displacement threshold, then the terminal device performs RNAU; or,

[0093] If the first relative distance is greater than the first displacement threshold, the terminal device performs RNAU; or,

[0094] If the first relative distance is less than the second displacement threshold, the terminal device performs RNAU; or,

[0095] If the first relative distance is greater than or equal to the second displacement threshold and less than or equal to the first displacement threshold, then the terminal device performs RNAU; or,

[0096] If the first relative distance is greater than the second displacement threshold and less than or equal to the first displacement threshold, then the terminal device performs RNAU; or,

[0097] If the first relative distance is greater than or equal to the second displacement threshold and less than the first displacement threshold, the terminal device performs RNAU.

[0098] Optionally, the first displacement threshold is greater than the second displacement threshold.

[0099] Optionally, the configuration information for event-triggered RNAU may also include: displacement-related information of the terminal device. The displacement-related information includes: a first displacement threshold and / or a second displacement threshold.

[0100] It should be understood that the aforementioned first displacement threshold and / or second displacement threshold may also be excluded from the configuration information of the event-triggered RNAU. For example, the first displacement threshold and / or second displacement threshold may be predefined. In short, this application does not restrict the method of obtaining the first displacement threshold and / or second displacement threshold.

[0101] In summary, in this application, the terminal device performs RNAU based on the configuration information for event-triggered RNAU and the motion information of the terminal device. Compared with existing RNAU triggering methods, this approach avoids frequent RNAU triggering, thereby reducing the power consumption of the terminal device.

[0102] Example 4

[0103] As described above, the terminal device can perform RNAU based on the configuration information for event-triggered RNAU and the motion information of the terminal device. This will be explained in detail below:

[0104] Optionally, the configuration information for event-triggered RNAU includes: displacement-related information of the terminal device. The displacement-related information includes: a third displacement threshold. The motion information of the terminal device is its current position information. Based on this, the terminal device can determine a second relative distance relative to the default position reference point information, based on its current position information and the default position reference point information.

[0105] If the second relative distance is greater than or equal to the third displacement threshold, then the terminal device performs RNAU; or,

[0106] If the second relative distance is greater than the third displacement threshold, the terminal device performs RNAU.

[0107] Optionally, the default location reference point information is the geographical location of the terminal device when it was last released to the inactive state or the geographical location of the terminal device when it last received the first configuration information, but is not limited to these.

[0108] In summary, in this application, the terminal device performs RNAU based on the configuration information for event-triggered RNAU and the motion information of the terminal device. Compared with existing RNAU triggering methods, this approach avoids frequent RNAU triggering, thereby reducing the power consumption of the terminal device.

[0109] Example 5

[0110] As described above, the terminal device can perform RNAU based on the configuration information for event-triggered RNAU and the motion information of the terminal device. This will be explained in detail below:

[0111] Optionally, the configuration information for event-triggered RNAU includes: location-related information and displacement-related information of the terminal device; the location-related information includes: location reference point information; the displacement-related information includes: a third displacement threshold. Based on this, the terminal device can determine a first relative distance relative to the location reference point information based on the current location information and the location reference point information; and determine a second relative distance relative to the default location reference point information based on the current location information and the default location reference point information.

[0112] If the first relative distance is greater than or equal to the first displacement threshold, and the second relative distance is greater than or equal to the third displacement threshold, then the terminal device performs RNAU; or,

[0113] If the first relative distance is less than or equal to the second displacement threshold, and the second relative distance is greater than or equal to the third displacement threshold, then the terminal device performs RNAU; or,

[0114] If the first relative distance is greater than the second displacement threshold and less than the first displacement threshold, and the second relative distance is greater than or equal to the third displacement threshold, then the terminal device performs RNAU; or,

[0115] If the first relative distance is greater than or equal to the first displacement threshold, and the second relative distance is greater than the third displacement threshold, then the terminal device performs RNAU; or,

[0116] If the first relative distance is greater than the first displacement threshold, and the second relative distance is greater than or equal to the third displacement threshold, then the terminal device performs RNAU; or,

[0117] If the first relative distance is greater than the first displacement threshold, and the second relative distance is greater than the third displacement threshold, then the terminal device performs RNAU; or,

[0118] If the first relative distance is less than or equal to the second displacement threshold, and the second relative distance is greater than the third displacement threshold, then the terminal device performs RNAU; or,

[0119] If the first relative distance is less than the second displacement threshold, and the second relative distance is greater than or equal to the third displacement threshold, then the terminal device performs RNAU; or,

[0120] If the first relative distance is less than the second displacement threshold, and the second relative distance is greater than the third displacement threshold, then the terminal device performs RNAU; or,

[0121] If the first relative distance is greater than the second displacement threshold and less than or equal to the first displacement threshold, and the second relative distance is greater than or equal to the third displacement threshold, then the terminal device performs RNAU; or,

[0122] If the first relative distance is greater than the second displacement threshold and less than or equal to the first displacement threshold, and the second relative distance is greater than the third displacement threshold, then the terminal device performs RNAU, etc.

[0123] In summary, in this application, the boundary value involved in the displacement threshold range, i.e. the case of equality, can exist in any displacement threshold range where the boundary value is located, or it can exclude the boundary value. This application does not impose any restrictions on this.

[0124] Optionally, the default location reference point information is the geographical location of the terminal device when it was last released to the inactive state or the geographical location of the terminal device when it last received the first configuration information, but is not limited to these.

[0125] Optionally, the configuration information for event-triggered RNAU may also include: displacement-related information of the terminal device. The displacement-related information includes: a first displacement threshold and / or a second displacement threshold.

[0126] It should be understood that the aforementioned first displacement threshold and / or second displacement threshold may also be excluded from the configuration information of the event-triggered RNAU. For example, the first displacement threshold and / or second displacement threshold may be predefined. In short, this application does not restrict the method of obtaining the first displacement threshold and / or second displacement threshold.

[0127] In summary, in this application, the terminal device performs RNAU based on the configuration information for event-triggered RNAU and the motion information of the terminal device. Compared with existing RNAU triggering methods, this approach avoids frequent RNAU triggering, thereby reducing the power consumption of the terminal device.

[0134] It should be understood that, in this application, the terminal device, network device, or other device can plan the global geographic locations as a series of geographic networks, with each geographic grid or location corresponding to at least one of the following: CGI, TAC, and RANAC. In this application, this correspondence, i.e., the mapping relationship between at least one location and at least one of CGI, TAC, and RANAC, can be referred to as the first mapping relationship. Based on this, the terminal device can combine its current location information and the first mapping relationship to determine at least one of the first CGI, first TAC, and first RANAC corresponding to the current location information, and perform or not perform RNAU based on the matching result of at least one of the first CGI, first TAC, and first RANAC with at least one of the location-related information.

[0135] Optionally, the terminal device may determine whether to perform RNAU in the following ways, but is not limited to these:

[0136] If at least one of the first CGI, first TAC, and first RANAC matches at least one of the location-related information, the terminal device does not perform RNAU. If at least one of the first CGI, first TAC, and first RANAC does not match the location-related information, the terminal device performs RNAU. Alternatively, if at least one of the first CGI, first TAC, and first RANAC matches at least one of the location-related information, the terminal device performs RNAU. If at least one of the first CGI, first TAC, and first RANAC does not match the location-related information, the terminal device does not perform RNAU.

[0137] Optionally, the terminal device may obtain the first mapping relationship through at least one of the following methods, but is not limited to:

[0138] (1) Pre-configuration method.

[0139] (2) Non-Access Stratum (NAS) signaling notification method.

[0157] In summary, in this application, the terminal device performs RNAU only upon triggering the aforementioned preset event. Compared to existing RNAU triggering methods, this approach avoids frequent RNAU triggering, thereby reducing the power consumption of the terminal device.
