SMF 102 controls UPF 108 via N4 interface.

[0040] RAN 103 (or access network equipment) is the access equipment that UE 109 uses to access the network architecture wirelessly. It is mainly responsible for wireless resource management, quality of service (QoS) management, data compression and encryption, etc. on the air interface side.

[0041] In some embodiments of the present application, the access network device may be a device for communicating with a mobile device. The access network device may be an access point (AP) in WLAN, a base station (BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (eNB or eNodeB) in LTE, or a relay station or access point, or an in-vehicle device, a wearable device, and an access network device (gNB) in an NR network, or an access network device in a future evolved PLMN network, or an access network device in an NTN network, etc.

[0042] By way of example and not limitation, in some embodiments of the present application, the access network device may have a mobile characteristic, for example, the access network device is a mobile device. Alternatively, the access network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, or the like. Alternatively, the access network device may be a base station located on land, in water, or the like.

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

[0044] In some embodiments of the present application, AMF 101, SMF 102, AUSF 104, UDM 105, PCF 106, DN 107, and UPF 108 are network elements of the core network (referred to as: core network network elements).

[0045] The AMF network element can be used to manage the terminal's access to the core network, such as terminal location update, network registration, access control, terminal mobility management, terminal attachment and detachment, etc. The AMF network element can also provide control plane storage resources for the session while providing services for the terminal's session, to store the session identifier, the SMF network element identifier associated with the session identifier, etc.

[0046] The SMF network element can be used to select a user plane network element for the terminal, redirect the user plane network element for the terminal, allocate an Internet Protocol (IP) address to the terminal, establish a bearer (also called a session) between the terminal and the UPF network element, modify and release the session, and control QoS.

[0047] AUSF is used to receive the request from AMF to authenticate the terminal, request the key from UDM, and then forward the issued key to AMF for authentication processing.

[0048] UDM includes functions such as the generation and storage of user subscription data and the management of authentication data, and supports interaction with external third-party servers. PCF network elements are used to provide policies such as QoS policies and slice selection policies to AMF network elements and SMF network elements.

[0049] A DN can provide data services to users on networks such as IP Multimedia Service (IMS) and the Internet. A DN can contain multiple application servers (ASs) that provide different application services, such as carrier services, Internet access, or third-party services. ASs implement application functions (AFs).

[0050] The UPF network element is mainly responsible for the transmission of user data. Other network elements can be called control plane function network elements, which are mainly responsible for authentication, authorization, registration management, session management, mobility management and policy control to ensure reliable and stable transmission of user data.

[0051] The UPF network element can be used to forward and receive data from the terminal. For example, the UPF network element can receive service data from the data network and transmit it to the terminal through the access network device; the UPF network element can also receive user data from the terminal through the access network device and forward it to the data network. Among them, the transmission resources allocated and scheduled by the UPF network element for the terminal are managed and controlled by the SMF network element. The bearer between the terminal and the UPF network element may include: the user plane connection between the UPF network element and the access network device, and the establishment of a channel between the access network device and the terminal. Among them, the user plane connection is a quality of service (QoS) flow that can be established between the UPF network element and the access network device to transmit data.

[0052] The AF network element is used to interact with the core network element to support the routing of application data.

[0057] As an example and not a limitation, in the embodiment of the present application, the terminal device may also be a wearable device. Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0058] It should be noted that the network architecture of the communication system shown in FIG1 does not constitute a limitation on the network architecture of the communication system of the embodiment of the present application. In a specific implementation, the communication system may also include more or fewer network elements than those shown in FIG1, or combine certain network elements. It should be understood that the RAN in FIG1 may also be represented by an AN.

[0059] For example, the communication system shown in Figure 1 may further include a Network Exposure Function (NEF), which may be connected to other network elements in the communication system shown in Figure 1 through corresponding interfaces. The NEF network element is used to provide external exposure to network capabilities and events, and to receive relevant external information.

[0060] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system shown in FIG1 as an example, the communication device may include an access network device having a communication function (e.g., RAN 103), a core network element (e.g., PCF 106), and a UE 109.

[0061] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0062] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0063] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0064] In the embodiments of the present application, "pre-defined" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device or a network device). The present application does not limit the specific implementation method. For example, pre-defined may refer to information defined in a protocol.

[0065] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the present application are explained.

[0066] Zero-power communication is a wireless communication technology suitable for short-distance, low-speed communications. Zero-power devices primarily combine RF energy harvesting, backscattering, and low-power computing technologies to achieve the advantage of device nodes not carrying a power supply.

[0067] The core of RF energy harvesting is to convert RF energy into DC. The energy can be stored in batteries or capacitors, or it can be directly used to drive logic circuits, digital chips or sensor devices after collection, to complete the modulation and transmission of backscattered signals, the collection and processing of sensor information and other functions and applications.

[0068] As shown in Figure 2, a typical zero-power communication system (such as a Radio Frequency Identification (RFID) system) includes a network device (such as a reader / writer of an RFID system) and a zero-power device (such as an electronic tag). The network device is used to send wireless power supply signals, downlink communication signals, and receive backscattered signals from the zero-power device to the zero-power device. A basic zero-power device includes an energy harvesting module, a backscatter communication module, and a low-power computing module. In addition, the zero-power device may also have a memory or sensor for storing some basic information (such as item identification, etc.) or sensor data such as ambient temperature and ambient humidity.

[0069] For example, the energy harvesting module can collect energy carried by radio waves in space (Figure 2 shows radio waves emitted by network devices) to drive the low-power computing module of the zero-power device and implement backscatter communication. After obtaining energy, the zero-power device can receive control commands from the network device and send data to the network device based on control signaling using backscattering. The data sent can be data stored in the zero-power device itself (such as an identity identifier or pre-written information, such as the product's production date, brand, manufacturer, etc.). The zero-power device can also be loaded with various sensors, so that the data collected by various sensors can be reported based on the zero-power mechanism.

[0070] With the development of NR systems, it is considered that NR systems support zero-power terminal access to the network. The main scenarios have the following characteristics:

[0071] The environment is extreme and not suitable for ordinary terminal work;

[0072] Use very low power consumption and cost terminals;

[0073] No battery terminals.

[0074] Zero-power communication systems can be used in scenarios such as wireless industrial sensing networks, smart agriculture, smart warehousing and logistics, and smart homes.

[0075] Based on the energy source and usage of zero-power devices, zero-power devices can be divided into the following types:

[0076] 1. Passive zero-power devices

[0077] Zero-power devices (such as electronic tags in RFID systems) do not require internal batteries. When a zero-power device is close to a network device (such as an RFID reader), it is within the near-field radiation generated by the network device's antenna. Consequently, the zero-power device's antenna generates an induced current through electromagnetic induction, which drives the device's low-power chip circuitry. This enables forward link signal demodulation and reverse link (or reflection link) signal modulation. For backscatter links, the zero-power device uses backscattering to transmit signals.

[0078] It can be seen that the passive zero-power device does not require a built-in battery to drive either the forward link or the reverse link, and is a truly zero-power device.

[0079] Passive zero-power devices do not require batteries, and the RF circuit and baseband circuit are very simple. For example, they do not require low-noise amplifiers (LNAs), power amplifiers (PAs), crystal oscillators, analog-to-digital converters (ADCs), and other devices. Therefore, they have many advantages such as small size, light weight, very low price, and long service life.

[0080] Other features of this type of zero-power device include: 1) no battery; 2) obtaining energy from the surrounding environment (such as radio waves, solar energy, wind energy, mechanical kinetic energy, etc.); and 3) no Universal Subscriber Identity Module (USIM) card. They can also store a certain amount of energy from the surrounding environment, but the energy is very low, so the functional logic they support is much less than that of ordinary terminals.

[0081] 2. Semi-passive zero-power devices

[0082] Semi-passive zero-power devices do not have conventional batteries themselves, but instead use RF energy harvesting modules to harvest radio wave energy and store it in an energy storage unit (such as a capacitor). This energy is then used to power the low-power chip circuitry of the zero-power device, performing tasks such as demodulating forward link signals and modulating reverse link signals. For backscatter links, the zero-power device uses backscattering to transmit signals.

[0083] It can be seen that the semi-passive zero-power device does not require a built-in battery to drive either the forward link or the reverse link. Although it uses energy stored in capacitors during operation, the energy comes from the radio energy collected by the energy harvesting module. Therefore, it is also a truly zero-power device.

[0084] Semi-passive zero-power devices inherit many advantages of passive zero-power devices, so they have many advantages such as small size, light weight, very low price, and long service life.

[0085] 3. Active zero-power devices

[0086] In some scenarios, zero-power devices can also be active zero-power devices, which can have built-in batteries. The batteries power the low-power chip circuitry in these devices, enabling forward link signal demodulation and reverse link signal modulation. However, for backscatter links, zero-power devices use backscattering to transmit signals. Therefore, the zero-power nature of these devices lies primarily in the fact that reverse link signal transmission does not require the terminal's own power, but rather utilizes backscattering.

[0087] Active zero-power terminals use a built-in battery to power the RFID chip, increasing the tag's read and write distance and improving communication reliability. Therefore, they are suitable for scenarios with relatively high requirements for communication distance and read latency.

[0088] Zero-power devices can connect to the base station directly or through a relay device. The former is called direct mode, and the latter is called indirect mode.

[0089] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0090] FIG3 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG3 , the method 200 includes at least part of the following:

[0091] S210, the terminal device reports the mobile information of the terminal device to the target network device according to the target information or the first indication information, wherein the target information is the configuration information for the terminal device to report the mobile information, and the first indication information is used to instruct the terminal device to report the mobile information, or in other words, the first indication information is used to trigger the terminal device to report the mobile information.

[0092] In some embodiments, the terminal device is an Internet of Things (IOT) device.

[0093] In some embodiments, the terminal device is an energy harvesting-based IoT (Ambient Power Enabled IoT, AIoT) device, etc.

[0094] In some embodiments, the terminal device may be an energy harvesting-based device, such as a zero-power device, and may not have a battery, or may have limited energy storage capabilities, such as energy storage through capacitors.

[0095] In some embodiments, the terminal device is a type of device with low complexity, small size or low power consumption.

[0096] In some embodiments, the target information may be obtained from the first network device.

[0097] In some embodiments, the method 200 further includes:

[0098] The terminal device receives target information sent by the first network device.

[0099] In some embodiments, the first network device may be a core network device, such as an AMF entity.

[0100] It should be understood that the present application does not limit the specific signaling by which the first network device sends the target information to the terminal device, such as sending it through a NAS message.

[0101] In some embodiments, the target information is sent by the first network device to the terminal device via a registration acceptance message.

[0102] For example, the terminal device may send a registration request message to the first network device. Further, the first network device may reply to the terminal device with a registration acceptance message, where the registration acceptance message carries target information.

[0103] In some embodiments, the registration request message includes second indication information for indicating whether the terminal device is an environment-enabled IoT device, such as AMP IoT, or for indicating whether the terminal device supports environment-enabled IoT or supports energy harvesting. Optionally, the second indication information may be carried in the capability information of the terminal device.

[0104] Optionally, the second indication information can be 1 bit, and the value of this 1 bit is used to indicate whether the terminal device is an environment-enabled Internet of Things device and whether it supports environment enablement. For example, a value of 1 indicates support, and a value of 0 indicates non-support.

[0105] In some embodiments, the first indication information is obtained from an access network device.

[0106] In some embodiments, the method 200 further includes:

[0107] The terminal device receives first indication information sent by the access network device.

[0108] In some embodiments, the access network device may receive target information sent by the first network device, and further trigger the terminal device to report movement information based on the target information.

[0109] Optionally, the first network device may send an N2 message to the access network device, where the N2 message carries target information.

[0110] In some embodiments, the access network device may periodically trigger the terminal device to report the mobility information according to the reporting period of the mobility information of the terminal device, that is, periodically send the first indication information to the terminal device.

[0111] In some embodiments, the target network device may be an access network device, or may be a core network device, such as an AMF entity.

[0112] In some embodiments, when the reporting object of the terminal device's mobile information is an access network device (that is, the target network device is an access network device), the terminal device can send access layer (Access Stratum, AS) information to the access network device, and the AS message includes the terminal device's mobile information.

[0113] In other embodiments, when the reporting object of the terminal device's mobile information is a core network device (that is, the target network device is a core network device), the terminal device can send non-access stratum (NAS) information to the core network device, and the NAS message includes the terminal device's mobile information.

[0114] When a terminal device reports mobility information to an access network device, the terminal device does not need to enter the connected state, or in other words, the terminal device does not need to complete the connection establishment process with the access network device, which is beneficial to power saving for the terminal device. When a terminal device reports mobility information to a core network device, the terminal device needs to enter the connected state.

[0115] In the embodiment of the present application, the movement information is also called location update information.

[0116] Optionally, the mobile information of the terminal device may include but is not limited to at least one of the following:

[0118] Movement distance information of the terminal device;

[0119] Movement route information of the terminal device;

[0120] Timestamp information when the terminal device moves.

[0121] In some embodiments, the target information is configuration information used by the terminal device to report movement information.

[0122] For example, the target information is used to configure the method in which the terminal device reports the mobility information, such as the reporting object, reporting cycle, reporting conditions, etc.

[0123] In some embodiments, the target information includes at least one of the following:

[0127] In some embodiments, the first information may be one or more bits, the values ​​of which are used to indicate whether the terminal device needs to report the mobility information. For example, the first information is one bit, and when the value of the one bit is 1, it indicates reporting, otherwise, it indicates not reporting.

[0128] In other embodiments, when the target information includes a specific indication bit, the terminal device is instructed to report the mobility information; when the target information does not include the specific indication bit, the terminal device is not instructed to report the mobility information.

[0129] That is, whether to report the mobility information may be indicated by explicit information, or may be indicated by whether to carry specific information.

[0130] In some embodiments, the second information is used to indicate a receiving device to which the terminal device reports the mobile information, that is, a reporting object.

[0131] For example, the second information is used to instruct the terminal device to report mobile information to the access network device, or to report mobile information to the core network device, such as reporting mobile information to the AMF entity.

[0135] In some embodiments, the reference location information used to determine the movement distance of the terminal device includes identification information of a reference terminal and / or identification information of an access point device. That is, the reference terminal or access network device can be the reference device, and the movement distance of the terminal device can be based on the location of the reference device.

[0136] In some embodiments, the reference terminal may be an anchor terminal (Anchor UE).

[0137] In some embodiments, the terminal device may determine whether the terminal device has moved and / or the moving distance based on a change in the distance between the terminal device and a reference device.

[0138] Exemplarily, when the distance change between the terminal device and the reference device is less than a first threshold, it is determined that the terminal device has not moved.

[0139] Exemplarily, when the moving distance of the terminal device exceeds a moving distance threshold, the movement information of the terminal device is reported.

[0142] In some embodiments, the reporting object for the terminal device to report mobility information may also be predefined, for example, predefined to report mobility information to the access network device, or predefined to report mobility information to the core network device. In this case, the first network device may not need to configure the reporting object information for the terminal device.

[0143] In some embodiments, the area information in which the terminal device reports the movement information may also be predefined, for example, the terminal device is predefined to report the movement information in a specific area. In this case, the first network device may not need to configure the area information for the terminal device.

[0144] In some embodiments, the moving distance threshold for the terminal device to report movement information may also be predefined. In this case, the first network device may not need to configure the moving distance threshold for the terminal device.

[0145] In some embodiments, the reference location for determining the movement distance of the terminal device may also be predefined, for example, the location of a specific terminal or access network device may be predefined as the reference location. In this case, the first network device may not need to configure the reference location information for the terminal device.

[0146] In some embodiments, the reporting period for the terminal device to report the movement information may also be predefined. In this case, the first network device may not need to configure the reporting period for the terminal device.

[0147] In some embodiments of the present application, the method 200 further includes:

[0148] The first network device obtains target information from the second network device.

[0149] In some embodiments, the second network device may be a core network device, for example, the second network device is a UDM entity.

[0151] Optionally, the UDM entity may carry the target information in the contract information of the terminal device.

[0152] Optionally, the AF entity may carry the target information in the authorization information of the terminal device.

[0153] In some embodiments, when the first network device does not receive the target information sent by the UDM entity, the target information sent by the AF entity may be used as the configuration information for the terminal device to report the mobility information. When the first network device receives the target information sent by both the UDM entity and the AF entity, the specific configuration for the terminal device to report the mobility information may be determined by comprehensively considering the target information sent by both the UDM entity and the AF entity. For example, the reporting configuration indicated by the UDM entity may be preferentially selected.

[0154] In some embodiments, S210 may include:

[0155] The terminal device may report the movement information of the terminal device according to the area information and / or the movement distance threshold for reporting the movement information of the terminal device.

[0156] For example, if the terminal device is in the first area and the moving distance of the terminal device meets the moving distance threshold, the movement information of the terminal device is reported, and the first area belongs to the valid area for reporting movement information configured by the target information.

[0157] In some embodiments, the terminal device can determine whether it has moved based on its own hardware, such as a vibrator, or it can use a positioning application to determine whether it has moved and the distance it has moved. This application does not limit the method for determining whether the terminal device has moved and the specific movement distance.

[0158] In some embodiments, S210 may include:

[0159] The terminal device may report the movement information of the terminal device according to the periodic information of the terminal device reporting the movement information.

[0160] That is, the terminal device can periodically report mobility information so that the network device can perform mobility management on it.

[0161] In some embodiments, the first network device may receive the mobility information reported by the terminal device according to a reporting period for the terminal device to report the mobility information. For example, when the reporting object is the first network device, the first network device receives the mobility information reported by the terminal device according to the reporting period.

[0162] For example, the first network device receives the movement information reported by the terminal device according to the first timer;

[0163] The duration of the first timer is determined according to the reporting period of the mobile information of the terminal device.

[0164] Optionally, if the first network device has not received the mobile information reported by the terminal device when the first timer times out, the first network device sends a third indication message to the second network device, and the third indication message is used to indicate the update of the reporting period of the mobile information of the terminal device.

[0165] Below, in combination with Figures 4 and 5, taking the first network device as an AMF entity, the second network device as a UDM entity or an AF entity, and the access network device as a RAN as an example, the implementation process of the wireless communication method according to the embodiment of the present application is explained from the perspective of device interaction.

[0168] S301, the UE sends a registration request message to the AMF entity, and the registration request message includes second indication information, which is used to indicate whether the terminal device is an environment-enabled IoT device and whether it supports environment enablement. For example, a value of 1 indicates support, and a value of 0 indicates non-support.

[0169] Optionally, the second indication information may be 1 bit.

[0170] Optionally, the second indication information may be carried in a 5GMM capability parameter.

[0171] S302: The AMF entity requests the UE's subscription information from the UDM entity.

[0173] Optionally, the subscription request includes identification information (Identity, ID) of the UE.

[0174] S303, the UDM entity replies with a subscription response to the AMF entity.

[0175] In some embodiments, the subscription response carries the subscription information of the UE, and the configuration information used for the UE to report the mobility information, that is, the target information is also carried in the subscription information.

[0176] For example, the subscription response may carry first information, which is used to indicate that the UE needs to notify the network of its own mobility information.

[0177] For another example, the subscription response may carry second information for indicating the object to which the UE reports mobility information, such as a core network device or an access network device.

[0183] Optionally, the authorization information of the UE includes a UE ID.

[0184] In some cases, if the UDM entity does not reply to the subscription response, the AMF entity uses the target information obtained from the AF entity as the configuration information for the UE to report mobility information.

[0185] In some embodiments, if the AMF entity obtains target information from both the UDM entity and the AF entity, the reporting configuration configured by the AMF entity for the UE can be determined based on the target information obtained from both the UDM entity and the AF entity.

[0190] S306: The UE reports mobility information according to the target information.

[0191] For example, if the UE is configured to report mobility information to the RAN, the UE may carry the mobility information in an AS message and send it to the RAN. In this case, the UE does not need to enter a connected state, which is beneficial to power saving of the UE.

[0192] For another example, if the UE is configured to report mobility information to the core network device, the UE may carry the mobility information in a NAS message and send it to the core network device, wherein the UE needs to enter a connected state.

[0193] In the example of FIG5 , the terminal device may report mobility information based on a trigger of the RAN.

[0197] Optionally, the second indication information may be carried in a 5GMM capability parameter.

[0198] S312: The AMF entity requests the UE's subscription information from the UDM entity.

[0200] Optionally, the subscription request includes identification information (Identity, ID) of the UE.

[0201] S313, the UDM entity replies with a subscription response to the AMF entity.

[0202] In some embodiments, the subscription response carries the subscription information of the UE, and the configuration information used for the UE to report the mobility information, that is, the target information is also carried in the subscription information.

[0203] For example, the subscription response may carry first information, which is used to indicate that the UE needs to notify the network of its own mobility information.

[0204] For another example, the subscription response may carry second information for indicating the object to which the UE reports mobility information, such as a core network device or an access network device.

[0205] For another example, the signing response may also carry third information for indicating the reporting conditions for the UE to report the mobility information, such as the reporting period.

[0206] Optionally, the signing response may include fourth indication information, used to indicate that the UE is an environment-enabled IoT device.

[0207] Optionally, in some embodiments, it also includes: S314, the AMF entity obtains the authorization information of the UE from the AF entity.

[0208] For example, the AMF entity obtains the UE's authorization information from the AF entity through the NEF entity.

[0209] In some embodiments, the authorization information of the UE carries configuration information for the UE to report mobility information, ie, the target information.

[0210] Optionally, the authorization information of the UE includes a UE ID.

[0211] In some cases, if the UDM entity does not reply with a signing response, the AMF entity shall take the target information obtained from the AF entity as the basis.

[0212] In some embodiments, if the AMF entity obtains target information from both the UDM entity and the AF entity, the reporting configuration configured by the AMF entity for the UE can be determined based on the target information obtained from both the UDM entity and the AF entity.

[0213] S315: The AMF entity sends an N2 message to the RAN.

[0214] In some embodiments, target information is included in the N2 message.

[0215] In some embodiments, the N2 message includes indication information for indicating acceptance of the UE's registration request.

[0216] In some embodiments, the AMF entity may start a first timer according to the reporting period of the UE's mobility information, and receive the mobility information reported by the UE based on the first timer.

[0217] Optionally, if the mobility information reported by the UE has not been received when the first timer times out, the UDM or AF is notified to update or adjust the period for reporting the mobility information of the UE.

[0218] S316: RAN triggers the UE to report mobility information according to the target information.

[0219] For example, the RAN periodically triggers the UE to report mobility information according to a reporting period.

[0220] Optionally, the RAN may send RRC signaling to the UE, where the RRC signaling includes first indication information, where the first indication information is used to instruct the UE to report mobility information or location information.

[0221] In summary, the terminal device can report mobility information based on the configuration information for reporting mobility information, for example, reporting mobility information when the moving distance exceeds a certain threshold time, or reporting mobility information according to a certain period, etc. Therefore, the terminal device can report its own mobility information in a timely manner, thereby enabling the network device to realize mobility management of the terminal device.

[0222] In other implementations, the terminal device may also report mobility information based on the triggering of the access network device. For example, the access network device may periodically trigger the terminal device to report mobility information, so that the network device can obtain the mobility information of the terminal device in a timely manner, thereby realizing mobility management of the terminal device.
