Among them, the vertical industry control center (also known as the control center) refers to the management equipment used to control the movement path and speed of the control terminal equipment in the vertical industry (such as in the 4G vertical industry). The vertical industry control center It can be used to formulate the moving path and moving speed of the terminal device according to the type of the terminal device or the terminal device identification (used to identify the terminal device) and other information, so that the terminal device can move according to predetermined rules or perform corresponding operations.

Specifically, the terminal devices described herein may be of different types. For example, the terminal device may be a non-mobile device or a mobile device, or it may be a car, an aircraft, or a robot. The type of terminal device is related to the behavior characteristics of the terminal device. For example, if the terminal device is a non-mobile device, a device with a slow moving speed, or a device with a short moving distance, the terminal device generally does not switch to the access network device. Exemplarily, the vertical industry control center may identify the type of terminal device through the type identification of the terminal device or other type information. In addition, the type of terminal equipment can be distinguished according to the group ID of the terminal equipment. For example, the vertical industry control center can configure the same group identifier for the same type of terminal equipment, or use the type identifier of the terminal equipment as the group identifier. .

Optionally, as shown in FIG. 4, the wireless communication system may further include management equipment for access network equipment, such as RAN operation administration and maintenance (OAM) equipment. In this application, the RAN OAM can interact with the NVAF through the interface with the NVAF. It should be understood that this application uses RAN OAM as an example to describe the operations performed by the management equipment of the access network equipment, but it should not be understood that this application can only use RAN OAM as the management equipment of the access network equipment in the implementation. In 5G or future communications, such as 6G, the management device of the access network device can still be a RAN OAM network element or have other names, which is not limited in this application.

To solve the problems mentioned in the background art, based on the architecture shown in FIG. 4, this application provides a UE management method. As shown in FIG. 5, the method may include the following steps shown in S101 to S104:

S101: The vertical industry control center sends first path information of the terminal device to the path information management network element, where the first path information includes location information of the movement path of the terminal device. Correspondingly, the path information management network element receives the first path information from the terminal device of the vertical industry control center.

S102: The path information management network element obtains second path information of the terminal device according to the first path information of the terminal device. Wherein, the second path information includes the information of the target access network device and the path ID corresponding to the target access network device, the path ID corresponding to the target access network device and the terminal device in the target access network Corresponds to the movement path within the management area of the device. It can be understood that the management area of each target access network device covers or partially covers the movement path of the terminal device.

S103: The path information management network element sends the second path information of the terminal device to the first access network device, the target access network device includes the first access network device, and the path identifier corresponding to the target access network device includes the Path identifier corresponding to the first access network device. Correspondingly, the first access network device receives the second path information of the terminal device.

S104: The first access network device determines the location information of the movement path of the terminal device in the management area of the first access network device according to the path identifier corresponding to the first access network device.

Using the above method, the path information management network element can obtain the movement path of the terminal device in the management area of each access network device, and instruct the access network device to manage the terminal device in the access network device by way of path identification. The movement path within the area. Since the path identifier corresponding to the target access network corresponds to the movement path of the terminal device in the management area of the access network device, when sending the second path information of the terminal device to the target access network, the target access network device may The corresponding path identifier determines the movement path of the terminal device in its own management area, and realizes the encrypted instruction of the movement path of the terminal.

In the implementation of the steps shown in S101 above, the first path information of the terminal device may include some or all of the following information: the identification of the terminal device, the location information of the movement path of the terminal device, and the movement of the terminal device. Time, the moving speed of the terminal device or the type information of the terminal device.

The identification of the terminal device can be used to indicate the terminal device associated with the movement path, and the identification of the terminal device can include the SUPI of the UE or other identification can be used to uniquely determine the identification of the terminal device in the current growth scenario.

In this application, the movement path of the terminal device refers to the route that the terminal device moves in the current vertical industry scenario, and the route may pass through the management area of one or more access network devices in the scenario. The location information of the moving path of the terminal device can be expressed by the geographic coordinates of the moving path. For example, when the vertical industry control center controls the terminal device to move according to the moving path, it can indicate the moving path represented by continuous or discontinuous geographic coordinates to the terminal. equipment. In addition, the mark points (for example, a workshop, factory building, intersection, or pre-set mark positions, etc.) of the alternative movement path can also be marked in advance (for example, the mark of one or more mark points passing through), Therefore, the vertical industry control center can also instruct the terminal device to move according to the movement path corresponding to the identification through the identification of one or more landmark points. At this time, the position information of the movement path of the terminal device may include the identification of one or more landmark points. . The movement path of the terminal device may also include the movement direction of the terminal device. For example, when the movement path is represented by geographic coordinates, the first geographic coordinate may indicate the starting point of the moving path, and the last geographic coordinate may indicate the end point of the moving path. Or, when the movement path of the terminal device is indicated by the mark of the mark point, the mark of the previous mark point can be used to indicate the mark point passed by the terminal device, and the mark of the subsequent mark point can be used to indicate the mark passed by the terminal device. For example, when the first path information carries the identification ID 1 and ID 2 of the path identification mark point, the position carried by ID 1 is first, which means that the terminal device first passes the mark point identified by ID 1 and the position carried by ID 2 is After that, it means that the terminal device passes through the landmark point identified by ID 2 and the first path information may indicate that the terminal device moves from the landmark point identified by ID 1 to the landmark point identified by ID 2.

The above mobile time of the terminal device can be used to indicate when the terminal device starts to move. In addition, the movement time of the terminal device can also be used to indicate the time when the terminal device moves to and/or leaves a certain position on the movement path. Alternatively, the moving time of the terminal device can also be used to indicate the time when the terminal device moves to and/or leaves a certain area.

The above moving speed of the terminal device can be used to indicate the speed of the terminal device moving along the moving path. The terminal device can move at an even speed according to the moving speed, or move at different speeds in different path segments, which is not specifically limited in this application. According to the moving speed of the terminal device combined with the moving time of the terminal device, it can be determined when the terminal device moves to and/or leaves the management area of a certain access network device.

The above type information of the terminal device may include the type identifier of the terminal device or other information that can be used to indicate the type of the terminal device, such as a group identifier or other type indication information. According to the type information of the terminal device, it can be determined whether the terminal device is moving, or the speed of the terminal device moving. The type information of the terminal device can also be used to indicate whether the access network device serving the terminal device needs to be switched during the operation.

In a possible implementation manner, in the step shown in S102 above, the path information management network element may determine the connection according to the first correspondence and the position information of the terminal device's movement path within the management area of the target access network device. Path identifier corresponding to the connected device. Exemplarily, the first correspondence may include the information of the access network device (such as the identification of the access network device or the location information of the access network device), the location information in the management area of the access network device, and the path identification. Correspondence between. It should be understood that the location information in the management area of the access network device described herein may include all or part of the location information (such as geographic coordinates and/or location) of the road that can be used by the terminal device in the management area of the access network device. Identification), location information of landmarks passing by (such as geographic coordinates and/or identification of landmarks) or other information that can be used to indicate location.

The above first correspondence can be represented by a correspondence table between the information of the access network device, the location information in the management area of the access network device, and the path identifier. Among them, different access network equipment can be distinguished by the information of the access network equipment. The correspondence table can be as shown in Table 1.

Table 1

Exemplarily, K1, K11, and K111 in Table 1 above represent landmark points, and K2, K3, K4, K5, and L5 represent roads, respectively. According to Table 1, the terminal devices indicated by the same path identifier have different moving paths in the management areas of different access network devices. For example, the path ID "path ID_1" can be used to indicate that the mobile path of the terminal device in the management area of the access network device gNB_1 is from the mark point K1 to the mark point K11 and finally to the mark point K111, and the access network device gNB_1 is the terminal The access network equipment that the equipment passes through is the target access network equipment. The path ID "path ID_1" can also be used to indicate that the moving path in the management area of the access network device gNB_2 is K2. At this time, the access network device gNB_2 is the access network device through which the terminal device passes, that is, the target access network device. Therefore, when the path information management network element sends path ID_1 to the access network device gNB_1, the access network device gNB_1 can determine according to Table 2 that the mobile path of the terminal device in the management area of the access network device gNB_1 is reached by the marker point K1 The mark point K11 finally reaches the mark point K111. Similarly, when the path information management network element sends path ID_1 to the access network device gNB_2, the access network device gNB_2 can determine that the terminal device is in the management area of the access network device gNB_2 The moving path is K2. Specifically, the movement path within the management area of the access network equipment such as K1, K2, etc. may be represented by geographic coordinates indicating the starting point, the end point and one or a group of intermediate points of the path.

In addition, in the step shown in S104, the access network device may determine the position information of the movement path of the terminal device within the management area managed by the terminal device according to the second correspondence relationship and the second path information of the terminal device, wherein the second correspondence relationship Including the corresponding relationship between the location information and the path identifier in the management area of the access network device. The correspondence table can be as shown in Table 2.

路径标识Path identification	终端设备在接入网设备gNB_1的管理区域内的移动路径The movement path of the terminal device in the management area of the access network device gNB_1
path ID_1path ID_1	K1，K11，K111K1, K11, K111
path ID_2path ID_2	K3K3
path ID_3path ID_3	K5K5

Table 2

Exemplarily, the foregoing second correspondence relationship is only stored in the access network device associated with the second correspondence relationship. For example, the path identifier and the movement path table of the terminal device in the management area of the access network device gNB_1 shown in Table 2 are only stored in the access network device gNB_1, and other access network devices are not stored in this table. Correspondence relationship to improve the safety of route indication.

The second correspondence is included in the first correspondence. For example, as shown in Table 2, the path identifier corresponding to the movement path "K1, K11, K111" in the management area of the access network device gNB_1 is the path identifier path ID_1. The path identifier for the moving path "K1, K11, K111" in the management area of the access network device gNB_1 shown in 1 is the path identifier path ID_1.

It should be understood that the first correspondence described in this application can be sent to the path information management network element by a vertical industry control center such as NVAF, or by an access network management device such as RAN OAM. The first correspondence may also be pre-configured in the path information management network element.

In addition, it should be understood that the above second correspondence can be sent to the access network device by RAN OAM, NVAF, or other network elements in the network. In addition, it can also be stored in the access network device in a pre-configured manner.

In addition, in the implementation of the steps shown in S102 above, the path information management network element can determine the management area of the terminal device based on the location information of the management area of one or more access network devices and the first path information of the terminal device. One or more access network devices to which these management areas belong may be referred to as target access network devices in this application. Here, the management area of the access network equipment may refer to the area covered by the network cell (or cell) of the access network equipment. In the management area, the terminal equipment can access the cell of the access network equipment. . The path information management network element can store the location information of the management area of one or more access network devices, for example, store the correspondence between the identification of the access network device and the location information of the coverage area of the management area, and the location information of the management area The location information of the coverage area may include geographic coordinate information of the coverage area, or an identification (such as a serial number) representation of the coverage area.

It should be understood that the location information of the management area of the access network device described in this application can be sent to the path information management network element by the vertical industry control center such as NVAF, or by the access network management device such as RAN OAM. Alternatively, the location information of the management area of the access network device may be stored in the path information management network element in a pre-configured manner.

Exemplarily, if the management area covers or partially covers the movement path of the terminal device, the access network device to which the management area belongs may be used as the target access network device corresponding to the terminal device. For example, as shown in Figure 6A, if the mobile path of terminal device A in the vertical industry scenario is represented as A1, and the cell coverage of access network device B is B1, it can be seen that B1 covers A1. At this time, the access network device B is the target access network device. As shown in Figure 6B, if the mobile path of terminal device C in the vertical industry scenario is represented as C1, the cell coverage of access network device D is D1, and the cell coverage of access network device E is E1, it can be seen , D1 and E1 both partially cover C1. At this time, the access network devices D and E can be used as target access network devices.

In addition, if there are multiple target access network devices corresponding to the terminal device, the path information management network element can also determine the order in which the terminal device accesses each target access network device according to the location information of the management area of the target access network device. order. Specifically, NVAF can determine the target access network device to which the management area that the terminal device passes first on the moving path of the terminal device belongs to, as the target access network device that the terminal device first accesses, and the location of the management area that the terminal device passes after on the moving path. The attribution target access network device is the target access network device that is accessed after the terminal device. For example, as shown in Figure 6B, the moving path C1 first passes through D1 and then enters E1, so the access network device D is the target terminal device that terminal device C accesses first, and the access network device E is the target terminal device that terminal device C accesses later .

In the above step S102, the path information management network element may determine the movement path of the terminal device within the management area of the target access network device according to the location information of the management area of the target access network device and the first path information of the terminal device . For example, as shown in FIG. 6B, the movement path of the terminal device C in the management area of the access network device D is positions Ca to Cc, and the movement path of the terminal device in the management area of the access network device E is positions Cb to Cd, where , The terminal device positions Ca, Cb, Cc, and Cd are all approach points of the movement path C1. Exemplarily, the location information of the locations Ca and Cc may be used to indicate the movement path of the terminal device C in the management area of the access network device D, and/or the location information of the locations Cb and Cd may be used to indicate that the terminal device is at The movement path within the management area of the access network equipment E. Take location Ca as an example. The location information of Ca here can include the coordinate information of Ca, or include the logo of the landmark point (such as factory building, workshop, or intersection) where Ca is located, or include the logo of Ca (such as Ca is a landmark) ). After determining the movement path of the terminal device in the management area of the target access network, the path information management network element may determine the path identifier corresponding to the target access network according to the aforementioned method. For example, the path information management network element may determine the path identifier corresponding to the target access network device according to the first correspondence and the movement path of the terminal device in the management area of the target access network.

It should be understood that the first path information may also include the location information of the terminal device in the management area of the access network device, so that the path information management network element can determine the management of the access network device that the terminal device is passing through according to the first path information The movement path within the area. At this time, NVAF or RAN OAM can determine the movement path of the terminal device in the management area of the access network device according to the first path information of the terminal device and the location information of the management area of one or more access network devices. The specific method is The path information management network element can refer to the method for determining the movement path of the terminal device in the management area of the access network device. Thereafter, NVAF or RAN OAM can carry the location information of the movement path, such as coordinates, in the first path information. Or geographic location identifier.

Exemplarily, the second path information of the terminal device involved in the embodiment of the present application may also include the identification of the terminal device, the location information of the mobile path of the terminal device, the time when the terminal device enters the management area of the target access network device, and / Or part or all of the information in the time when the terminal device leaves the management area of the target access network device. Among them, the path information management network element can determine the time when the terminal device enters the management area of the target access network device and/or the terminal device leaves according to the movement path of the terminal device, and the movement time of the terminal device and/or the movement speed of the terminal device The time of the management area of the target access network device.

The second path information of the terminal device may also include type information of the terminal device, for example, the type identification of the terminal device. The type information of the terminal equipment can be used in the network (core network equipment and/or access network equipment) for corresponding configuration. For example, when the type information of the terminal device indicates that the terminal device does not need to switch the access network device, the AMF and/or the access network device serving the terminal device can be configured according to the type information of the terminal device, such as the configuration does not support the terminal The equipment switches the access network equipment; when the type information of the terminal equipment indicates that the terminal equipment is moving faster, the AMF and/or the access network equipment serving the terminal equipment can be configured according to the type information of the terminal equipment to support The terminal equipment performs switching of the access network equipment with a higher frequency.

Exemplarily, if there are multiple target access network devices corresponding to the terminal device, the second path information of the terminal device may also include the sequence of the terminal device passing through the management area of each target access network device. For example, if the second path information of the terminal device successively carries the identifiers of the access network device a, the access network device b, and the access network device c, then the second path information indicates the movement path of the terminal device, which passes through the access network sequentially. Management area of equipment a, access network equipment b, and access network equipment c. Exemplarily, the sequence is consistent with the sequence in which the terminal device accesses multiple target access network devices. The access network device serving the terminal device can determine the mobile location of the terminal device according to the sequence to determine the next access network device. The access network device sends a handover request to the access network device.

The index shown in Table 3 can be used to indicate the order in which the terminal device accesses the target access network. For example, indexes 1 to 3 can respectively indicate the first, second, and third access network devices of the terminal device, namely The terminal device first accesses gNB_1, then switches from gNB_1 to gNB_2, and finally switches from gNB_2 to gNB_3; or index 1 to 3 can indicate the third, second, and first access network devices of the terminal device respectively, namely The terminal device first accesses gNB_3, then switches from gNB_3 to gNB_2, and finally switches from gNB_2 to gNB_1. t_1/t_2 respectively indicate the time when the terminal device moves to/leaves the target access network indicated by gNB_1. t_3/t_4 respectively indicate the time when the terminal device moves to/leaves the target access network indicated by gNB_2. t_5/t_6 respectively indicate the time when the terminal device moves to/leaves the target access network indicated by gNB_3.

According to the second path information, the first access network device can learn that the terminal device is in the first The mobile path within the management area of the access network device can provide more effective network support for the terminal device. For example, the access network device can learn that the terminal device is about to move out of its management area based on the movement path, so as to determine the need to perform Cell handover of terminal equipment.
