Technical field

The present application relates to the field of communication technology, and in particular to a cell information configuration method, device, readable storage medium and chip system.

Background technique

In order to improve network capacity and coverage, a relay node that supports wireless backhaul transmission is proposed to implement dense network deployment. Devices that support relay functions are referred to as relay devices (can also be called relays or relay nodes). Relay devices provide similar functions and services to ordinary base stations for terminals accessing their cells. Relay devices and terminals The communication link between them is called the access link. The relay device accesses a base station serving it in a terminal-like manner through a wireless interface. The base station is called a donor base station. The wireless interface link between the relay device and the donor base station is called a backhaul link. road (backhaul link).

In the fifth generation (the fifth generation, 5G) new radio (NR) research, integrated access and backhaul (integrated access and backhaul) that integrates wireless access links and wireless backhaul links are proposed. IAB) node. The IAB node can access the network through its mobile terminal (Mobile-Termination, MT) function, and then the operations administration and maintenance (OAM) device configures cell information for the IAB node. The cell information can be included in the IAB node. Configured tracking area code (TAC). Existing IAB nodes are fixed relay devices on the ground. When a terminal device accesses the fixed IAB node, the network side can determine the location of the terminal device based on the TAC of the IAB node cell currently accessed by the terminal device.

With the development of technology, mobile relay devices are required in many application scenarios. For example, a mobile base station relay (also known as vehicle mounted relay (VMR)) is proposed based on the vehicle scenario. The VMR node can be configured in the vehicle and can move with the vehicle. The VMR can be in the vehicle Or the terminal equipment near the car provides services. It can be understood that the VMR node is an IAB node with mobile capabilities. VMR can also be called a mobile relay. Similar to the existing IAB architecture introduced earlier, the VMR node can use a wireless interface similar to The terminal accesses a base station that serves it. The base station can be called a donor base station. The wireless interface link between the relay device and the donor base station is called a backhaul link.

In addition, the VMR node can also access the network through its mobile terminal (mobile-termination, MT) function, and then the OAM device configures cell information for the VMR node.

Currently, how to configure cell information for relay devices with mobile capabilities has become an urgent problem that needs to be solved.

Contents of the invention

This application provides a cell information configuration method, device, readable storage medium and chip system for configuring cell information for relay equipment with mobile capabilities.

In a first aspect, this application provides a method for configuring cell information, which method can be executed by a relay device with mobile capabilities or a unit, module or chip within the relay device. For easy understanding, in the embodiments of this application, the relay device with mobility capability is called a mobile relay. This application takes the method executed by a mobile relay as an example for illustration. The mobile relay is in a moving state, and is used to provide relay services between terminal equipment and access network equipment. The access network device may also be called the host base station of the mobile relay. The method includes:

The mobile relay sends the location information of the mobile relay to the management device, and the location information of the mobile relay is used to obtain the cell configuration information of the mobile relay. The mobile relay receives cell configuration information of the mobile relay from the management device. The cell configuration information of the mobile relay includes the first TAC, and the first TAC is determined based on the location information of the mobile relay.

In order to illustrate the beneficial effects brought by this method, a comparison scheme is introduced below. In this comparison scheme, the TAC of the mobile relay is not determined based on the location information of the mobile relay. For example: the management device configures a fixed TAC for the mobile relay cell, such as TAC#1. The mobile relay is located at the first position, and the TAC included in the broadcast message sent by mobile relay 3 is TAC#1. When the mobile relay moves from the first position to the second position (for example, the cell corresponding to the first position is different from the cell corresponding to the second position), the TAC of mobile relay 3 does not change, and the broadcast message sent by mobile relay 3 The TAC included in is still TAC#1. Because for a terminal device that accesses the mobile relay, the TAC of the mobile relay that the terminal device accesses is always TAC#1. Therefore, even if the mobile relay has moved to the second position, the network side may still think that the mobile relay is at the first position, and then determine that the terminal device accessing the mobile relay is also near the first position. It can be seen that configuring a fixed TAC for the mobile relay will cause the network side to determine incorrect location information for the UE accessing the mobile relay.

In the embodiment of the present application, since the TAC of the mobile relay cell is determined based on the location information of the mobile relay, the network side (such as network elements, network side equipment, devices, etc.) The TAC of the relay determines the location information of the mobile relay, and then the current location of the terminal device accessing the mobile relay can be determined relatively accurately. It can be seen that the cell information configuration method provided by this application can configure cell configuration information for a relay with mobility capabilities.

The location information of the mobile relay in this application may include various forms, and it only needs to be able to indicate the location of the mobile relay. For example, the location information of the mobile relay may include: at least one of the second TAC of the first cell of the first access network device accessed by the mobile relay, the identity of the first cell, or the identity of the first access network device. item. The location information of the mobile relay may also include information on the geographical area of the location where the mobile relay is located. Among them, there is at least one item of information on the geographical area where the mobile relay is located. The information of the geographical area may include at least one of a longitude area range, a latitude area range, or a geographical area identifier (the geographical area identifier may include, for example, an administrative region identifier, etc.). In addition, the first access network device accessed by the mobile relay may refer to the access network device currently accessed by the MT function of the mobile relay. When the mobile relay accesses the first access network device, the first access network device may also be called the host base station of the mobile relay.

In this way, the flexibility of the solution can be improved. Furthermore, when the location information of the mobile relay includes the TAC of the cell of the access network device to which the mobile relay is connected, in a possible implementation, the management device may assign the TAC to the cell of the access network device to which the mobile relay is connected. The TAC is determined to be the TAC of the cell of the mobile relay, that is, the first TAC is the same as the second TAC of the first cell of the access network device accessed by the mobile relay. This solution is relatively simple and easy to implement. It is worth noting that it is only a possible implementation that the management device determines the TAC of the cell that the mobile relay accesses as the TAC of the cell of the mobile relay. The TAC configured by the management device for the cell of the mobile relay can also be configured with the TAC of the cell of the mobile relay. The TAC of the cell that the mobile relay accesses is different, that is, the first TAC is different from the second TAC of the first cell of the access network device that the mobile relay accesses.

In this application, in order to improve the flexibility of the solution, there are multiple ways for the mobile relay to determine location information. For example, the mobile relay receives a first broadcast message from the first cell of the access device, and the first broadcast message includes the second TAC of the first cell of the access network device accessed by the mobile relay, the identity of the first cell, or At least one of the identifiers of the access network equipment. In this way, the mobile relay may obtain at least one of the second TAC of the first cell of the access network device accessed by the mobile relay, the identity of the first cell, or the identity of the access network device obtained from the first broadcast message. A piece of location information as a mobile relay is sent to the management device, which can save the signaling consumed by the mobile relay in querying location information from other network elements.

For another example, before the mobile relay sends the location information of the mobile relay to the management device, the mobile relay queries the core network device for the location of the mobile relay, and the mobile relay receives the location information of the mobile relay from the core network device. The location information of the mobile relay may include information about the geographical area where the mobile relay is located. The information of the geographical area may include at least one of longitude area range, latitude area range, or geographical area identification, etc.

In a possible implementation, after the mobile relay determines that the mobile relay has moved, the mobile relay sends the location information of the mobile relay to the management device.

Since the mobile relay sends the moved location information to the management device after determining that the mobile relay has moved, the management device can re-configure the TAC for the cell of the mobile relay based on the moved location information of the mobile relay, thereby achieving dynamic The effect of configuring TAC for the mobile relay is that the network side can more accurately determine the current location of the terminal device based on the TAC of the mobile relay accessed by the terminal device.

In a possible implementation, the mobile relay determines that the mobile relay has moved based on at least one of the TAC of the cell where the mobile relay accesses, a cell identity, or an identity of the access network device. For example, the mobile relay receives a second broadcast message from the second cell of the second access network device, and the second broadcast message includes at least one of the third TAC, the identity of the second cell, or the identity of the second access device. item. After the mobile relay receives the second broadcast message, the mobile relay receives the first broadcast message of the first cell of the first access network device, where the first broadcast message includes the second TAC of the first cell of the first access network device. , the identity of the first cell, or at least one of the identity of the first access network device. The mobile relay determines that the mobile relay has moved when it is determined that at least one of the following contents is satisfied: the second TAC is different from the third TAC, the identity of the first cell is different from the identity of the second cell, or, the first cell The identifier of the access device is different from the identifier of the second access device.

It can be seen that the mobile relay will receive broadcast messages in different cells, and then the mobile relay can determine whether the mobile relay has moved based on the information carried in the broadcast message, and then when it is determined that movement has occurred, notify the management device Send location information.

On the other hand, the mobile relay determines whether the mobile relay has moved based on at least one of the second TAC of the first cell of the first access network device, the identity of the first cell, or the identity of the first access network device. , it can also prevent the mobile relay from frequently sending the location information of the mobile relay. For example, a mobile relay is always in a moving state, but it does not mean that the mobile relay will send location information to the management device when it moves any distance. Instead, the mobile device needs to move within a preset movement range before sending the location information to the management device. For example, if the mobile device moves out of the cell it is currently accessed, the movement of the mobile device satisfies the preset movement range. When the mobile relay determines that at least one of the TAC, cell identity, and access network equipment of the accessed cell changes, the mobile relay may move out of the currently accessed cell. Therefore, the mobile relay When the mobile relay moves, it is determined based on at least one of the TAC of the cell where the mobile relay accesses, the cell identity, and the access network equipment to which the mobile relay accesses, that the mobile relay's movement will satisfy the preset movement range to a large extent. Therefore, The mobile relay determines the time when the mobile relay moves based on at least one of the TAC of the cell where the mobile relay accesses, the cell identity, and the access network equipment to which the mobile relay accesses. to send location information.

In another possible implementation, when the mobile relay determines that the mobile relay's movement satisfies the preset movement range, the mobile relay sends location information. For example, the preset movement range may include at least one of the following: the TAC of the cell accessed by the mobile relay changes, the cell identity of the cell accessed by the mobile relay changes, or the cell identity accessed by the mobile relay changes. The access network equipment changes.

For example, the preset mobility range includes: the TAC of the cell accessed by the mobile relay changes. In this case, when the TAC of the cell that the mobile relay determines to access changes, the mobile relay sends the location information of the mobile relay.

In another possible implementation, when the mobile relay determines that the movement of the mobile intermediate level does not meet the preset movement range, the mobile relay may not send location information.

For example, the preset mobility range includes: the TAC of the cell accessed by the mobile relay changes. In this case, when the mobile relay determines that the TAC of the accessed cell has not changed, it is possible that the mobile relay has a smaller moving range. In this case, the mobile relay can be allowed not to send location information. In this way, it can be avoided The mobile relay frequently sends the location information of the mobile relay to reduce signaling consumption.

For another example, the preset mobility range includes: the identity of the access network device connected to the mobility relay changes. In this case, when the mobile relay determines that the identity of the access network device has not changed, it is possible that the mobile relay's movement range is small. In this case, the mobile relay can be allowed not to send location information, so , which can prevent the mobile relay from frequently sending the location information of the mobile relay and reduce signaling consumption.

In a possible implementation, after the mobile relay receives the cell configuration information of the mobile relay from the management device, the mobile relay requests the access network device to activate the cell of the mobile relay, and the first TAC is used as the mobile relay TAC of the relay cell, so that the access network device activates the mobile relay cell according to the first TAC.

In the second aspect, embodiments of the present application provide a cell information configuration method, which can be executed by a mobile relay or a unit, module or chip within the mobile relay. This application takes the method executed by a mobile relay as an example for illustration. The mobile relay is in a moving state, and is used to provide relay services between terminal equipment and access network equipment. The method includes:

The mobile relay sends indication information to the management device, and the indication information is used to trigger the management device to obtain the location information of the mobile relay. The mobile relay receives the first TAC configured for the cell of the mobile relay from the management device, and the first TAC is determined based on the location information of the mobile relay.

Since the mobile relay sends the instruction information to the management device for triggering the management device to obtain the location information of the mobile relay, the management device can obtain the location information of the mobile relay based on the instruction information, and then obtain the location information of the mobile relay based on the location information of the mobile relay. Determine the TAC of the mobile relay, so the network side can determine the location information of the mobile relay based on the TAC of the mobile relay accessed by the terminal device, and then can more accurately determine the terminal accessing the DU cell of the mobile relay. The current location of the device. It can be seen that the cell information configuration method provided by this application can configure cell configuration information for a relay device with mobility capabilities.

In a possible implementation, the indication information for triggering the management device to obtain the location information of the mobile relay includes: indicating that the type of the mobile relay is a type of relay device with mobility capabilities; and/or, for Information indicating that the type of mobile relay is a vehicle-mounted relay equipment type.

In this way, the management device can determine based on the indication information that the relay device has mobility capability and belongs to the mobile relay. Instead, you can obtain the location information of the mobile relay.

In another possible implementation, relay devices without mobility capabilities may be called non-mobile relays. When the management device configures TAC for such non-mobile relays, it may be configured based on the location information of the non-mobile relays. TAC may also not be configured based on the location information of the non-mobile relay. When the management device determines that the relay device belongs to a non-mobile relay (for example, the management device does not receive the location information indication information from the relay device that is used to trigger the management device to obtain a mobile relay), it determines that the relay device belongs to a non-mobile relay; For another example, if the message sent by the relay device to the management device requesting to configure the cell configuration information of the relay device does not carry the location information indication information used to trigger the management device to obtain the mobile relay, then it is determined that the relay device is a non-mobile relay. ), and there is no need to configure TAC based on the location information of the non-mobile relay, the management device does not need to obtain the location information of the non-mobile relay, thereby saving signaling overhead.

In this application, there are many ways for the management device to determine that the relay device is a non-mobile relay. For example, if the management device does not receive the location information indication information from the relay device that is used to trigger the management device to obtain the mobile relay, then it determines that the relay device is a non-mobile relay. The relay equipment is a non-mobile relay. For another example, if the message sent by the relay device to the management device requesting to configure the cell configuration information of the relay device does not carry the location information indication information used to trigger the management device to obtain the mobile relay, then it is determined that the relay device is a non-mobile relay. .

In a possible implementation, the location information of the mobile relay includes: the second TAC of the first cell of the access network device accessed by the mobile relay, the identity of the first cell, or the identity of the access network device. at least one of. The first TAC is the same as or different from the second TAC of the first cell of the access network device accessed by the mobile relay.

The current location of the terminal equipment that exits the cell of the DU entity that accesses the mobile relay. It can be seen that the cell information configuration method provided by this application can configure cell configuration information for a relay with mobility capabilities.

In the fourth aspect, embodiments of the present application provide a cell information configuration method, which can be executed by a management device or a unit, module or chip within the management device.

It can be seen that the cell information configuration method provided by this application can configure cell configuration information for a relay with mobility capabilities.

In a possible implementation, the management device may obtain an association between the location and the TAC. The association may include an association between the location indicated by the location information of the mobile relay and the first TAC. The association may also be called correspondence. Relationships, mapping relationships, etc. can also be reflected in the form of mapping tables.

Detailed ways

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Figure 1a exemplarily shows a schematic diagram of a possible application scenario applicable to the embodiment of the present application. As shown in Figure 1a, this scenario includes one or more access network devices. In Figure 1a, the access network device includes a base station. 1 and base station 2 are taken as examples for illustration. Base station 1 includes cell 101 and cell 102, and base station 2 includes cell 103.

As shown in Figure 1a, this scenario includes mobile relay 3. Mobile relay 3 needs to perform cell selection when accessing the network, and subsequently initiates random access in the cell. The access network equipment corresponding to the cell accessed by mobile relay 3 can be called a host base station. In Figure 1a, mobile relay 3 is used as a vehicle-mounted relay for illustration. Figure 1a shows a possible driving path of the mobile relay 3. According to the driving path, the mobile relay 3 can sequentially access the cell 101 of the base station 1, the cell 102 of the base station 1 and the cell 103 of the base station 2. .

On the other hand, mobile relay can provide access services for other terminal devices. In Figure 1a, the terminal device is user equipment (UE) as an example. As shown in Figure 1a, the UE can access the cell of mobile relay 3. The UE may be a terminal device of a passenger riding on a vehicle in which the mobile relay 3 is deployed. Of course, it may also be a terminal device located at other locations, which is not limited by the embodiment of this application. Any two UEs among the three UEs shown in Figure 1a may be the same or different, and are not limited in this embodiment of the present application.

Since mobile relay 3 has mobile capabilities, if the solution of configuring a fixed TAC (such as TAC#1) for mobile relay 3 is adopted, the following problems will occur:

The mobile relay 3 is located at a first location (the first location is, for example, a location within the coverage area of the cell 101 of the base station 1), and the TAC included in the broadcast message sent by the mobile relay 3 is TAC#1. When the mobile relay moves from the cell 101 of base station 1 to a second location (the second location is, for example, a location within the coverage area of cell 102 of base station 1 or cell 103 of base station 2), the TAC of mobile relay 3 does not change. , the TAC included in the broadcast message sent by the mobile relay 3 is still TAC#1. Because for a UE accessing mobile relay 3, the TAC of mobile relay 3 accessed by the UE is TAC#1. Therefore, even if the mobile relay has moved to the second position, the network side may still think that the mobile relay 3 is at the first position, and then determine that the UE accessing the mobile relay 3 is also near the first position. It can be seen that configuring a fixed TAC for mobile relay 3 will cause the network side to determine incorrect location information for UEs accessing the mobile relay.

To address this problem, the embodiment of the present application aims to determine the TAC of mobile relay 3 based on the location information of mobile relay 3. Therefore, when the UE accesses the cell of mobile relay 3, the UE can obtain the cell of mobile relay 3. TAC. Then, the network side can determine the location of the UE based on the TAC of the mobile relay that the UE accesses. For example, the network side can first determine the current location of mobile relay 3 based on the TAC of the cell of mobile relay 3 that the UE accesses, and then obtain to the location of the UE. It can be seen that the solution provided by the embodiment of this application can configure TAC for the mobile relay.

Based on the content shown in at least one of the above-mentioned Figure 1a, Figure 1b, Figure 1c or Figure 1d and other content, Figure 2 exemplarily shows a flow chart of a possible cell information configuration method provided by the embodiment of the present application. .

Figure 2 takes the execution subject including mobile relay and management equipment as an example for introduction. The mobile relay involved in Figure 2 may be the mobile relay 3 in Figure 1a and Figure 1b. The management device involved in Figure 2 can be a device that has management authority for the mobile relay, for example, it can configure cell configuration information for the mobile relay. The solution on the mobile relay side in the embodiment of the present application can also be executed by units, modules or chips inside the mobile relay, and the solution on the management device side in the embodiment of the present application can also be executed by units, modules or chips inside the management device.

As shown in Figure 2, the method includes:

Step 201: The management device obtains the location information of the mobile relay.

In the embodiment of the present application, the mobile relay is in a moving state, which can also be understood to mean that the mobile relay has the ability to move, or that the mobile relay has the ability to move. Mobile relay is used to provide relay services between terminal equipment and access network equipment.

In step 201, the management device can obtain the location information of the mobile relay through multiple channels. For example, the mobile relay can send the location information to the management device. For another example, the management device can obtain the location information of the mobile relay from the core network device. For example, the management device can first subscribe to the core network device for the location information of the mobile relay. Or, for another example, the management device can query the core network device for the location information of the mobile relay. location information, etc.

The location information of the mobile relay in the embodiment of the present application may include various forms, and it only needs to be able to indicate the location of the mobile relay. For example, the location information of the mobile relay may include: the second TAC of the first cell of the first access network device accessed by the mobile relay (for distinction, the TAC of the first cell is called the second TAC in the embodiment of this application). ), at least one of the identifier of the first cell, the identifier of the first access network device, or information about the geographical area where the mobile relay is located. The information of the geographical area may include at least one of a longitude area range, a latitude area range, or a geographical area identifier (the geographical area identifier may include, for example, an administrative region identifier, etc.).

Step 202: The management device sends the first TAC to the mobile relay. The first TAC is determined based on the location information of the mobile relay. The first TAC is the TAC of the cell that is the mobile relay.

Correspondingly, the mobile relay receives the first TAC from the management device.

It can be seen from the solution shown in Figure 2 that since the TAC of the mobile relay's cell is determined based on the location information of the mobile relay, the network side can determine the mobile relay based on the TAC of the mobile relay accessed by the terminal device. The relayed location information can then be more accurately determined to determine the current location of the terminal equipment in the cell of the DU entity that accesses the mobile relay. It can be seen that the cell information configuration method provided by this application can configure cell configuration information for a relay with mobility capabilities.

The first TAC involved in the above step 202 and the second TAC of the first cell of the first access network device accessed by the mobile relay may be the same or different, and may be configured according to actual requirements.

In a possible implementation, when configuring a TAC for a mobile relay, the management device may not reuse the TAC of the cell of the access network device currently accessed by the mobile relay. In this way, the first TAC configured by the management device is the same as the second TAC configured by the management device. TAC is different. For example, the management device can configure a dedicated TAC for the mobile relay. In this way, the network side can determine that the terminal device accesses the cell of the mobile relay based on the TAC of the cell where the terminal device accesses.

In another possible implementation, when the management device configures the TAC for the mobile relay, the management device may configure the TAC of the mobile relay to be the TAC of the cell of the access network device accessed by the mobile relay, that is, the first TAC and The second TAC is the same. In this way, the network side can directly and accurately determine the current location of the terminal device based on the TAC of the mobile relay accessed by the terminal device. The solution is relatively simple.

In the above step 202, in a possible implementation, the management device may obtain the association between the location and the TAC. The association may include the association between the location indicated by the location information of the mobile relay and the first TAC. The association may be It can also be called correspondence relationship, mapping relationship, etc., and can also be embodied in the form of a mapping table. After receiving the location information of the mobile relay, the management device may determine that the TAC corresponding to the location information of the mobile relay is the first TAC based on the association relationship, and then send the first TAC to the mobile relay. In this way, the network side can determine the location of the mobile relay that the terminal device accesses based on the TAC of the mobile relay that the terminal device accesses and the location managed by the TAC, and then can obtain a more accurate current location of the terminal device.

It is worth noting that the association between the location indicated by the location information of the mobile relay and the first TAC may be preset. The association relationship may also be pre-stored on the management device side; it may also pre-exist in other devices (such as core network devices) or the cloud, and the management device obtains the association relationship from other devices (such as core network devices) or the cloud.

Based on the content shown in at least one of the above-mentioned Figure 1a, Figure 1b, Figure 1c, Figure 1d or Figure 2 and other content, Figure 3 exemplarily shows another cell information configuration method provided by the embodiment of the present application. Process diagram. The embodiment shown in FIG. 3 is an extended embodiment of the embodiment shown in FIG. 2 . As shown in Figure 3, the method includes:

Step 301: The mobile relay sends the location information of the mobile relay to the management device.

Correspondingly, the management device receives the location information of the mobile relay from the mobile relay.

Step 301 can be used as an implementation manner of step 201.

In the embodiment of this application, the mobile relay can obtain the location information of the mobile relay in multiple ways. For example, the mobile relay is currently connected to the first cell of the first access network device, and the mobile relay receives the first broadcast message. The first broadcast message is sent by the first access network device. The first broadcast message includes: at least one of the second TAC of the first cell of the first access network device, the identity of the first cell, or the identity of the first access network device. The second TAC is the TAC of the first cell. The mobile relay may send at least one of the second TAC of the first cell, the identity of the first cell, or the identity of the first access network device to the management device as location information.

For another example, the mobile relay can trigger the positioning process to obtain the location information of the mobile relay. For example, the mobile relay queries the core network device for the location of the mobile relay (for example, the mobile relay sends a message to the core network device to query the location of the mobile relay), and the mobile relay receives data from the core network. Location information for the device's mobile relay. The location information queried by the mobile relay from the core network device may include geographical location information of the location of the mobile relay. The location information queried by the mobile relay from the core network device may also include the second TAC of the first cell of the first access network device accessed by the mobile relay, the identity of the first cell, or the identity of the first access network device. At least one of the identifiers, etc. The embodiment of the present application does not limit the specific form of the location information.

Step 302: The management device sends the first TAC to the mobile relay. The first TAC is determined based on the location information of the mobile relay. The first TAC is the TAC of the cell that is the mobile relay.

For the relevant content of step 302, please refer to the relevant content of the aforementioned step 202.

Step 303: The mobile relay requests the first access network device to activate the cell of the mobile relay, and the first TAC is used as the TAC of the cell of the mobile relay.

In step 303, the mobile relay may send the first TAC to the first access network device, so that the first access network device obtains the TAC of the mobile relay's cell. Step 303 in the embodiment of this application may be an optional step.

It can be seen from the solution shown in Figure 3 that since the mobile relay can obtain the location information of the mobile relay by itself and send the location information to the management device, there is no need for the management device to obtain the location information of the mobile relay through other means, and the management The device can directly configure the TAC corresponding to the location information for the mobile relay cell based on the obtained location information, thereby avoiding the signaling consumption caused by the management device obtaining the mobile relay location information through other means. And since there are multiple ways for the mobile relay to determine location information, the solution provided in Figure 3 can improve the flexibility of the embodiment of the present application.

Based on the content shown in at least one of the above-mentioned Figures 1a, 1b, 1c, 1d, Figure 2 or 3 and other content, Figures 4a, 4b and 4c exemplarily introduce several possible cell information configurations. method. Figures 4a, 4b and 4c respectively show several possible expansion schemes of the embodiment shown in Figure 3.

As shown in Figure 4a, the method includes:

Step 401: The mobile relay sends a first message to the management device. The first message is used to obtain cell configuration information. The first message includes location information of the mobile relay.

Correspondingly, the management device receives the first message from the mobile relay.

Step 401 may be a possible implementation of the above step 301.

Step 402: The management device may send a response message to the first message to the mobile relay, where the response message to the first message carries cell configuration information, and the cell configuration information includes the first TAC.

Correspondingly, the mobile relay may receive cell configuration information from the management device.

In another possible implementation, the cell configuration information may also include cell identification and other information. Step 402 may be a possible implementation of the above-mentioned step 302 or step 202. For the process of the management device determining the first TAC, please refer to the relevant description of step 202, which will not be described again.

It is worth noting that the information interaction between the mobile relay and the management device in the embodiment of the present application can be the information interaction between the MT entity of the mobile relay and the management device, or it can also be the information interaction between the DU entity of the mobile relay and the management device. The information exchange between them is not limited by this application. The subsequent content is similar and will not be described again.

For example, in the above step 401, the mobile relay sending the first message to the management device may be the MT entity of the mobile relay sending the first message to the management device. In the above step 402, the response message in which the management device can send the first message to the mobile relay may be a response message in which the management device can send the first message to the MT entity of the mobile relay.

For another example, in the above step 401, the mobile relay sending the first message to the management device may be the DU entity of the mobile relay sending the first message to the management device. In the above step 402, the response message in which the management device can send the first message to the mobile relay may be a response message in which the management device can send the first message to the DU entity of the mobile relay.

Step 403: The mobile relay sends a second message to the first access network device, where the second message is used to request activation of the cell of the mobile relay.

In a possible implementation, the DU entity of the mobile relay can select an appropriate access network device as the host base station, such as selecting the first access network device as the host base station. Then, the DU entity of the mobile relay can select the first access network device as the host base station. The CU entity of the access network device sends the second message.

The second message may carry cell configuration information supported by the mobile relay. For example, it may carry part or all of the cell configuration information configured by the management device for the mobile relay. The first TAC may be included in the second message. The second message may also include information such as a cell identifier configured by the management device for the cell of the mobile relay. The second message can be an F1 setup request, which can be written as F1setup request in English.

Step 403 may be a possible implementation of the above step 303. Step 403 is an optional step and may or may not be executed.

Step 404: The first access network device sends target configuration information to the core network device.

The target configuration information may include the first TAC. In step 404, the first access network device may send target configuration information to the core network device through a configuration update process. In step 404, the first access network device may send a configuration update request message to the AMF, where the configuration update request message carries target configuration information. The target configuration information includes a tracking area identity (TAI) list supported by the first access network device. The TAI list supported by the first access network device may include a first TAI, and the first TAI may include a first TAC, So that the core network device (such as AMF) learns that the first access network device supports the first TAC.

Step 405: The first access network device sends a response message to the second message to the mobile relay.

The response message of the second message may carry the activated cell configuration information. For example, the response message of the second message may carry the cell identity of the activated mobile relay cell, and the activated cell identity of the mobile relay cell may include the identity of the first access network device.

The response message of the second message can be an F1 setup response, and can be written as F1setup response in English. Step 405 is an optional step and may or may not be executed.

Step 406: The mobile relay sends the third broadcast message.

In this embodiment of the present application, the mobile relay may send a broadcast message, such as the third broadcast message in step 406. The broadcast message sent by the mobile relay is used to send cell information corresponding to the cell of the mobile relay to the terminal device. The terminal device that receives the broadcast message can choose to access the cell and access the network through the mobile relay.

It is worth mentioning that in the embodiment of the present application, the mobile relay may send a broadcast message by the MT entity of the mobile relay, or the DU entity of the mobile relay may send a broadcast message. There is no limitation in the embodiment of the present application. Subsequent It will not be repeated in the content. For example, in step 406, the DU entity of the mobile relay sends the third broadcast message or the MT entity of the mobile relay sends the third broadcast message.

The third broadcast message may include the first TAC and/or the cell identity of the mobile relay. When the third broadcast message includes the first TAC, since the mobile relay can perform cell broadcast within the service range of the mobile relay, the terminal device located within the service range of the mobile relay can make the broadcast message received The mobile relay is accessed, and the accessed terminal device can determine that the TAC of the mobile relay is the first TAC according to the third broadcast message. Figure 4a shows an example of a terminal device receiving the third broadcast message.

It can be seen from the implementation shown in Figure 4a that the mobile relay can carry the location information of the mobile relay in the message requesting the management device to configure the cell configuration information of the mobile relay. In this way, there is no need for the management device to obtain the mobile relay through other means. The management device can directly configure the TAC corresponding to the location information for the cell of the mobile relay based on the obtained location information, thereby avoiding the signaling caused by the management device obtaining the location information of the mobile relay through other means. consumption. On the other hand, since the mobile relay sends location information to the management device, the management device can avoid configuring an incorrect TAC for the mobile relay, such as configuring a TAC that does not match the current location for the mobile relay. On the other hand, according to the embodiments of the present application, when the management device configures the cell configuration information for the mobile relay, the management device can configure the TAC for the cell of the mobile relay based on the location information of the mobile relay. In this way, the mobile relay initially performs cell configuration. During configuration, the TAC of the cell can be configured as a TAC related to the location information of the mobile relay, so that the network side can determine the actual location of the terminal device accessing the mobile relay, and improve the network's mobility management of the terminal device. efficiency and accuracy.

The following is an introduction to the embodiment shown in Figure 4b and Figure 4c. Part of the content in Figure 4b and Figure 4c is that the mobile relay moves after accessing the second cell, and moves from the second cell to the first access The first cell of network equipment is taken as an example for introduction. For the sake of distinction, in the embodiment of this application, the TAC of the second cell is called the third TAC, and the TAC of the first cell is called the second TAC.

The access network equipment corresponding to the second cell may be the same as the first access network equipment, or may be different. Among them, Figure 4b takes the example that the access network equipment corresponding to the second cell is the same as the first access network equipment. Figure 4c takes the example that the access network equipment corresponding to the second cell is different from the first access network equipment. introduce,

See Figure 4b. As shown in Figure 4b, the method includes:

Step 411: The mobile relay determines that the mobile relay has moved.

In the embodiment of the present application, when the mobile relay moves, it can be understood that both the MT entity of the mobile relay and the DU entity of the mobile relay move. The method for the mobile relay to determine that the mobile relay has moved may be that the MT entity of the mobile relay determines that the MT entity has moved, or the MT entity of the mobile relay determines that the mobile relay has moved.

In a possible implementation, a preset movement range can be set in advance. In step 411, when the mobile relay determines that the mobile relay's movement satisfies the preset movement range, the mobile relay determines that the mobile relay has moved.

In this embodiment of the present application, the preset movement range may include at least one of the following content 1, content 2, content 3, content 4 or content 5.

Content 1: The TAC of the cell accessed by the mobile relay changes.

Content 2: The cell identity of the cell accessed by the mobile relay changes.

Content 3: The access network equipment connected to the mobile relay changes.

Content 4: The information of the geographical area of the mobile relay changes.

Content 5: The moving distance of the mobile relay is greater than the preset distance.

The following is introduced respectively through case 1, case 2, case 3, case 4 and case 5.

It is worth noting that the following situations 1 to 5 are respectively introduced when the preset movement range includes one of the above content 1, content 2, content 3, content 4 and content 5. When the preset movement range includes multiple items (such as two items) in the above content 1, content 2, content 3, content 4 and content 5: the mobile relay can determine that the movement of the mobile relay satisfies the preset movement range. When at least one of the multiple items within the preset movement range is determined, the mobile relay may determine that the movement of the mobile relay satisfies the preset movement range; or, the mobile relay may determine that the movement of the mobile relay satisfies each of the multiple items within the preset movement range. , it is determined that the mobile relay movement meets the preset movement range. The method is relatively flexible and can be flexibly set according to the actual situation.

Case 1: The preset mobility range includes: the TAC of the cell accessed by the mobile relay changes.

The TAC of the cell accessed by the mobile relay changes, which may mean that the TAC of the cell accessed by the MT entity of the mobile relay changes. For example, the MT entity of the mobile relay receives the second broadcast message, and the second broadcast message includes TAC#8. Since the mobile relay has moved, after the MT entity of the mobile relay receives the second broadcast message, the MT entity of the mobile relay may also receive the first broadcast message, and the first broadcast message includes TAC#9. The MT entity of the mobile relay determines that when TAC#9 and TAC#8 are different, it determines that the mobile relay has moved, or that the mobile relay has moved to meet the preset movement range, or that the movement of the mobile relay satisfies Default movement range.

Case 2: The preset movement range includes: the cell identity of the cell accessed by the mobile relay changes.

The cell identity of the cell accessed by the mobile relay changes, which may mean that the cell identity of the cell accessed by the MT entity of the mobile relay changes. For example, the MT entity of the mobile relay receives the second broadcast message, and the second broadcast message includes cell identification #1. Since the mobile relay has moved, after the MT entity of the mobile relay receives the second broadcast message, the MT entity of the mobile relay may also receive the first broadcast message, where the first broadcast message includes cell identification #2. The MT entity of the mobile relay determines that when the cell identifier #2 is different from the cell identifier #1, it determines that the mobile relay has moved, or that the mobile relay has moved within the preset movement range, or that the mobile relay has moved The movement satisfies the preset movement range.

Case 3: The preset mobility range includes: the access network equipment connected to the mobile relay changes.

The access network equipment connected to the mobile relay changes, which may mean that the access network equipment connected to the MT entity of the mobile relay changes. For example, the MT entity of the mobile relay receives the second broadcast message, and the second broadcast message includes the identification #1 of the access network device. Since the mobile relay has moved, after the MT entity of the mobile relay receives the second broadcast message, the MT entity of the mobile relay may also receive the first broadcast message. The first broadcast message includes the identification of the access network device# 2. The MT entity of the mobile relay determines that the mobile relay has moved when the identifier #2 of the access network device is different from the identifier #1 of the access network device, or that the mobile relay has moved within the preset movement range. The movement, or the movement of the mobile relay, satisfies the preset movement range.

Case 4: The preset movement range includes: the information of the geographical area of the mobile relay changes.

The information on the geographical area of the mobile relay changes, which may mean that the information on the geographical area where the MT entity of the mobile relay is located changes. For example, when the MT entity of the mobile relay is located at the location corresponding to the information #1 of the geographical area, the positioning process is initiated to obtain the information that the current geographical location of the MT entity of the mobile relay is the information #1 of the geographical area from the core network. Since the mobile relay has moved, when the MT entity of the mobile relay initiates the positioning process again, the core The heart network obtains information #2 that the current geographical location of the MT entity of the mobile relay may be a geographical area. The MT entity of the mobile relay determines that when the geographical area information #2 is different from the geographical area information #1, it determines that the mobile relay has moved, or that the mobile relay has moved within a preset movement range, or that the mobile relay has moved within a preset movement range. The movement of the mobile relay satisfies the preset movement range.

Case 5, the preset movement range includes: the movement distance of the mobile relay is greater than the preset distance.

The moving distance of the mobile relay is greater than the preset distance, which may mean that the moving distance of the MT entity of the mobile relay is greater than the preset distance. The preset distance may be an experience value, and the preset distance may be related to the preset movement range. For example, when the moving distance of the mobile relay is greater than the preset distance, the mobile relay is likely to have moved out of the currently accessed access network device (or the cell of the currently accessed access network device, or the current corresponding TAC, or the geographic area to which it currently belongs).

For example, the preset distance can be set to 1000 meters. The mobile relay can query that the mobile relay's moving distance is greater than the preset distance by triggering the positioning process, or detect that the mobile relay's moving distance is greater than the preset distance through the detection device on the terminal device, or the mobile relay can infer the movement. The moving distance of the relay is greater than the preset distance (for example, inferred based on historical data), or the detection device on other devices detects that the moving distance of the mobile relay is greater than the preset distance and notifies the mobile relay, or other devices infer the movement. The moving distance of the relay is greater than the preset distance and the mobile relay is notified. When the mobile relay determines that the moving distance of the mobile relay is greater than the preset distance, it is determined that the mobile relay has moved, or that the mobile relay has moved within the preset movement range, or that the movement of the mobile relay satisfies the preset movement range. Set the movement range.

In another possible implementation, when the mobile relay determines that the mobile relay's movement does not meet the preset movement range, the mobile relay may not send location information. Alternatively, the mobile relay may attribute such a situation to a situation where the mobile relay determines that the mobile relay has not moved, or that the mobile relay has not moved within a preset movement range.

In a possible implementation, when the preset movement range includes any one of the above content 1, content 2, content 3, content 4 and content 5: when the mobile relay determines that the mobile relay has not moved If the content in the preset movement range is satisfied, the mobile relay determines that the movement of the mobile relay does not satisfy the preset movement range.

For example, the preset mobility range includes: the TAC of the cell accessed by the mobile relay changes. In this case, when the mobile relay determines that the TAC of the accessed cell has not changed, it is possible that the movement amount of the mobile relay is small. In this case, the mobile relay determines that the movement of the mobile relay does not meet the preset movement requirements. The range allows the mobile relay not to send location information. In this way, the mobile relay can avoid frequently sending the location information of the mobile relay and reduce signaling consumption.

In another possible implementation, in the case where the preset movement range includes multiple contents in the above content 1, content 2, content 3, content 4 and content 5: when the mobile relay determines that the mobile relay has not moved If every item in the preset movement range is satisfied, the mobile relay determines that the movement of the mobile relay does not satisfy the preset movement range. In other words, as long as any item in the preset movement range is met, the mobile relay can determine that its movement satisfies the preset movement range.

For example, the preset mobility range includes: the TAC of the cell accessed by the mobile relay changes, and the access network equipment accessed by the mobile relay changes. In this case, when the mobile relay determines that the TAC of the accessed cell has not changed, and the access network equipment to which the mobile relay is connected has not changed, the mobile relay determines that the movement of the mobile relay does not meet the preset movement requirements. range, it is possible to allow mobile relays not to send location information. For another example, when the mobile relay determines that the TAC of the cell it accesses has changed, but the access network equipment connected to the mobile relay has not changed, the mobile relay can also be allowed to send location information. This can be attributed to the mobile relay. The subsequent movement meets the preset movement range.

In yet another possible implementation, the preset movement range includes the above content 1, content 2, content 3, content In the case of multiple contents in 4 and 5: when the mobile relay determines that the movement of the mobile relay does not meet at least one of the contents in the preset movement range, the mobile relay determines that the movement of the mobile relay does not meet the preset movement. range, the mobile relay may not send location information. In this case, the mobile relay may determine that the movement of the mobile relay satisfies the preset movement range when determining that the movement of the mobile relay satisfies each of the multiple items within the preset movement range.

For example, the preset mobility range includes: the TAC of the cell accessed by the mobile relay changes, and the access network equipment accessed by the mobile relay changes. In this case, when the mobile relay determines that the TAC of the cell accessed has changed, but the access network equipment connected to the mobile relay has not changed, the mobile relay can be allowed not to send location information. For another example, when the mobile relay determines that the TAC of the cell accessed changes and the access network equipment connected to the mobile relay changes, the mobile relay is allowed to send location information.

Step 412: The mobile relay sends a third message to the management device, where the third message includes the location information of the mobile relay.

Correspondingly, the management device receives the third message from the mobile relay.

Since the mobile relay determines that the mobile relay has moved in step 411, the third message in step 412 carries the moved location information of the mobile relay.

In a possible implementation, the type of location information sent by the mobile relay may be associated with a preset movement range. For example, the type of location information sent by the mobile relay may be one or more of the types of location information corresponding to one or more contents included in the preset movement range.

For example, the preset mobility range includes: the TAC of the cell accessed by the mobile relay changes. Then, the type of location information sent by the mobile relay may include the TAC of the cell currently accessed by the mobile relay.

For another example, the preset mobility range includes: changes in the TAC of the cell to which the mobile relay is connected, changes to the cell identity of the cell to which the mobile relay is connected, and changes to the access network to which the mobile relay is connected. Equipment changes. Then, the type of location information sent by the mobile relay may include at least one of the TAC of the cell currently accessed by the mobile relay, the cell identifier, and the access network device identifier.

Step 412 may be a possible implementation of the above step 301.

Step 413: The management device may send a response message to the third message to the mobile relay, where the response message to the third message carries the first TAC.

Correspondingly, the mobile relay receives the response message of the third message from the management device.

Similarly, the third message may be sent by the MT entity of the mobile relay, and the response message to the third message may be sent by the management device to the MT entity of the mobile relay. The third message may also be sent by the DU entity of the mobile relay, and the response message of the third message may also be sent by the management device to the DU entity of the mobile relay. For relevant content, please refer to the above description and will not be repeated again.

In step 413, in a possible implementation, the management device may not determine whether the movement of the mobile relay satisfies the preset movement range. After receiving the third message, the management device can feed back the first TAC to the mobile relay.

In another possible implementation, the management device can also determine whether the movement of the mobile relay satisfies the preset movement range. For example, when the management device receives the third message and determines that the movement of the mobile relay satisfies the preset movement range, the management device feeds back the first TAC to the mobile relay. For another example, when the management device receives the third message and determines that the movement of the mobile relay does not meet the preset movement range, the management device does not feed back the first TAC to the mobile relay.

The preset movement range may include at least one of the aforementioned content 1, content 2, content 3, content 4 or content 5.

The solution for the management device to determine that the mobile relay has moved is similar to the previous solution for the mobile relay to determine that the mobile relay has moved, and will not be elaborated here. The difference is that the mobile relay obtains the TAC and cell number of the cell accessed by the mobile relay. The way in which the information about the area identifier, access network equipment, geographical area where the mobile relay is located, or the moving distance of the mobile relay may be somewhat different from the way in which the management device obtains this information. The management device can receive or query the mobile relay information. The TAC of the cell to which the relay is accessed, cell identity, access network equipment, information on the geographical area where the mobile relay is located, or the moving distance of the mobile relay. The embodiments of this application do not limit this.

In another possible implementation, when the mobile relay determines that the movement of the mobile relay meets the preset movement range, the mobile relay sends location information to the management device, and when the mobile relay determines that the movement of the mobile relay does not meet the preset movement range If the location is within the range, the location information may not be sent to the management device. In this case, the management device may not determine whether the movement of the mobile relay satisfies the preset movement range.

In another possible implementation, the mobile relay may obtain the location information and send it to the management device without determining whether the movement of the mobile relay satisfies the preset movement range. In this case, the management device can perform the step of judging whether the movement of the mobile relay satisfies the preset movement range, and feeds back the first TAC to the mobile relay when the movement of the mobile relay satisfies the preset movement range. If the subsequent movement does not meet the preset movement range, the first TAC will not be fed back to the mobile relay. The management device may also directly feed back the first TAC to the mobile relay without performing the step of determining whether the movement of the mobile relay satisfies the preset movement range.

It is worth noting that the situation in which the management device determines that the movement of the mobile relay does not meet the preset movement range is similar to the situation in which the mobile relay determines that the movement of the mobile relay does not meet the preset movement range, and will not be described again here.

Step 413 may be a possible implementation of the above step 302.

Step 414: The DU entity of the mobile relay sends a configuration update message to the first access network device, where the configuration update message is used to update the TAC of the cell of the mobile relay to the first TAC.

The first access network device side should store the TAC of the cell of the mobile relay corresponding to the position before the mobile relay moves. The TAC of the cell of the mobile relay corresponding to the position before the mobile relay moves is the same as the first TAC. different. After receiving the configuration update message, the first access network device updates the TAC of the mobile relay cell to the first TAC.

For example, the mobile relay is initially located at position 1, which is within the coverage of the second cell of the first access network device, and the mobile relay accesses the second cell at position 1. The mobile relay's cell The TAC is the TAC corresponding to position 1, and the TAC of the mobile relay cell stored on the first access network device side is the TAC associated with position 1. After that, the mobile relay moved to location 2. Location 2 is located within the coverage of the first cell of the first access network device. The mobile relay sent location 2 to the management device. The management device configured the mobile relay with Position 2 has the first TAC associated with it. The mobile relay sends the first TAC to the first access network device, so that the first access network device updates the mobile relay's TAC associated with position 1 to be associated with position 2. The first TAC of the relationship.

In a possible implementation, after step 414, the first access network device sends the updated first TAC of the mobile relay cell to the core network device through a configuration update process. For example, the first access network device may Send the first TAC to the AMF, so that the AMF learns that the first access network device supports the first TAC.

In another possible implementation, after step 414, the first access network device sends a response message to the configuration update message to the mobile relay. The response message of the configuration update message may indicate that the cell configuration information update of the mobile relay is completed.

After step 414, the mobile relay may perform step 415.

Step 415: The mobile relay sends the third broadcast message.

In this embodiment of the present application, the third broadcast message may include the identity of the first TAC and/or the cell of the mobile relay. For the content of step 415, please refer to the relevant content of step 406, which will not be described again.

It can be seen from Figure 4b that when the mobile relay moves within the preset movement range, the mobile relay can send the current location information of the mobile relay to the management device, so that the management device can calculate the location information after the mobile relay has moved. The cell of the mobile relay allocates TAC, which can achieve the effect that the TAC of the mobile relay is kept updated as it moves, that is, the TAC of the mobile relay is associated with the location of the mobile relay.

On the other hand, when the mobile relay moves but the host base station remains unchanged, the mobile relay can request the access network device to update the TAC of the mobile relay's cell, thereby maintaining the mobile base station's TAC stored on the host base station side. Accuracy of cell configuration information.

Please refer to Figure 4c below. In Figure 4c, the mobile relay moves out of the coverage area of the current access network equipment (for example, the mobile relay moves from the coverage area of the second access network equipment to the coverage area of the first access network equipment). , that is, the host base station of the mobile relay changes as an example.

As shown in Figure 4c, the method includes:

Step 421: The mobile relay determines that the mobile relay has moved.

Step 422: The mobile relay sends the third message to the management device.

Step 423: The management device may send a response message of the third message to the mobile relay.

For the content of step 421 to step 423, please refer to the aforementioned step 411 to step 413, which will not be described again here.

Step 424: The mobile relay sends a second message to the first access network device, where the second message is used to request activation of the cell of the mobile relay.

For the content of step 424, please refer to the relevant content of the aforementioned step 403, and will not be described again.

Step 425: The first access network device sends target configuration information to the core network device through a configuration update process.

The target configuration information may include the first TAC.

For the content of step 425, please refer to the relevant content of the aforementioned step 404, and will not be described again.

Step 426: The first access network device sends a response message to the second message to the mobile relay.

For the content of step 426, please refer to the relevant content of the aforementioned step 405, and will not be described again.

Step 427: The mobile relay sends the third broadcast message.

In a possible implementation, the third broadcast message includes the first TAC.

For the content of step 427, please refer to the relevant content of the aforementioned step 406, and will not be described again.

It can be seen from Figure 4c that when the mobile relay moves within the preset movement range, the mobile relay can send the current location information of the mobile relay to the management device, so that the management device can calculate the location information after the mobile relay has moved. The cell of the mobile relay allocates TAC, which can achieve the effect that the TAC of the mobile relay is kept updated as it moves, that is, the TAC of the mobile relay is associated with the location of the mobile relay.

On the other hand, when the mobile relay moves but the host base station changes, the mobile relay can request the new host base station to activate the cell of the mobile relay again, and will move when requesting the activation of the cell of the mobile relay. The relayed new TAC is sent to the new host base station, so that the accuracy of the cell configuration information of the mobile base station stored on the host base station side can be maintained.

Based on the content shown in at least one of the above-mentioned Fig. 1a, Fig. 1b, Fig. 1c, Fig. 1d, Fig. 2, Fig. 3, Fig. 4a, Fig. 4b or Fig. 4c and other contents, Fig. 5a and Fig. 5b exemplarily show A schematic flow chart of another possible cell information configuration method is provided. Figure 5a is an example where the mobile relay has not changed its host base station, and Figure 5b is an example where the mobile relay has changed its host base station. The embodiment shown in Figure 5a can be regarded as a combination of the two embodiments shown in Figure 4a and Figure 4b, and the embodiment shown in Figure 5b can be regarded as a combination of the two embodiments shown in Figure 4a and Figure 4c. The solutions of each embodiment are introduced respectively below.

As shown in Figure 5a, the method includes:

Step 501: The MT entity of the mobile relay receives the broadcast message a1 from access network device one.

The broadcast message a1 includes at least one of the TAC of cell 1 of access network device one, the identity of cell 1, or the identity of access network device one.

The broadcast message a1 may also include indication information that the cell corresponding to the broadcast message a1 supports mobile relay.

Step 502: The MT entity of the mobile relay performs cell selection and selects cell 1 for access.

In a possible implementation, the MT entity of the mobile relay can select a cell that supports the DU entity of the mobile relay for access based on the indication information carried in the broadcast message of whether to support mobile relay, such as the MT entity of the mobile relay. Select cell 1 for access.

Step 503: The MT entity of the mobile relay establishes an RRC connection with the access network device.

In step 503, the MT entity of the mobile relay may send an RRC connection establishment request message to the access network device. The RRC connection establishment request message may carry indication information indicating that the RRC connection is initiated by the mobile relay. The RRC connection establishment request message may include the RRC connection setup procedure.

Further, the access network device may send an RRC establishment completion message to the MT entity of the mobile relay. The RRC establishment completion message is used to indicate that the RRC connection is successfully established.

Step 504: The MT entity of the mobile relay sends a registration request message to the core network device.

Correspondingly, the core network device receives the registration request message.

In step 504, the MT entity of the mobile relay may send a registration request message to the core network device through the access network device.

Core network equipment may include AMF. The registration request message may carry indication information indicating that the registered network is a mobile relay, and then the core network device verifies the identity of the mobile relay. The registration request message may include N2message.

Step 505: The MT entity of the mobile relay is successfully registered.

In the embodiment of this application, the process of registering the MT entity of the mobile relay on the network is similar to the process of registering the terminal device on the network device, and will not be elaborated here.

Step 507: The mobile relay sends message a2 to the management device. Message a2 is used to obtain cell configuration information. Message a2 includes location information 1 of the mobile relay.

Correspondingly, the management device receives message a2 from the mobile relay.

Step 514: The MT entity of the mobile relay receives the broadcast message a5, where the broadcast message a5 includes at least one of the TAC of cell 2 of access network device one, the identity of cell 2, or the identity of access network device one.

The mobile relay may be in a moving state. When the mobile relay moves from cell 1 to cell 2, the mobile relay may receive the broadcast message a5. Then the mobile relay needs to perform cell selection again. For example, cell 2 can be selected as a new cell, and the mobile relay can access cell 2.

Step 515: The mobile relay determines that the mobile relay has moved.

In step 515, the mobile relay may determine that the mobile relay has moved based on at least one of the above content 1, content 2, content 3, content 4 or content 5.

When the mobile relay responds to the above content 1 (the TAC of the cell accessed by the mobile relay changes), content 2 (the cell identity of the cell accessed by the mobile relay changes) or content 3 (the cell the mobile relay accesses changes), When it is determined that the mobile relay has moved based on at least one of the following: changes in access network equipment), the mobile relay can determine that the mobile relay has moved based on the information carried in the broadcast message a5 received in step 514. In this case In this case, step 515 needs to be executed after step 514.

When the mobile relay determines that the mobile relay has moved based on at least one of the above content 4 (the information of the geographical area of the mobile relay changes) or content 5 (the moving distance of the mobile relay is greater than the preset distance), There is no sequential relationship between step 515 and step 514. For example, step 515 may be performed first and then step 514, which is not limited in the embodiment of this application.

For the relevant content of step 515, please refer to the relevant description of step 411, which will not be described again.

Step 516: The mobile relay sends message a6 to the management device. The message a6 includes the location information 2 of the mobile relay.

Step 518: The management device may send a response message to message a6 to the mobile relay, where the response message to message a6 carries TAC#3.

Correspondingly, the mobile relay receives the response message of message a6 from the management device.

Similarly, message a6 may be sent by the MT entity of the mobile relay, and the response message to message a6 may be sent by the management device to the MT entity of the mobile relay. Message a6 may also be sent by the DU entity of the mobile relay, and the response message to message a6 may also be sent by the management device to the DU entity of the mobile relay. For relevant content, please refer to the above description and will not be repeated again.

TAC#3 is used as the TAC of the cell serving as a mobile relay. For the relevant content of step 518, please refer to the relevant description of step 413, which will not be described again.

Step 519: The DU entity of the mobile relay sends a configuration update message to the access network device currently accessed by the MT entity of the mobile relay. The configuration update message is used to update the TAC of the cell of the mobile relay from TAC#2 to TAC#3.

For the relevant content of step 519, please refer to the relevant description of step 414, which will not be described again.

Step 520: The mobile relay sends broadcast message a7.

In a possible implementation, the broadcast message a7 may include TAC#3. For the content of step 520, please refer to the relevant content of the aforementioned step 415, and will not be described again.

It can be seen from the embodiment shown in Figure 5a that the MT entity of the mobile relay accesses cell 1 of access network device 1, and the management device allocates TAC#2 to the mobile relay based on the location information of cell 1 where the mobile relay is located. . When the mobile relay moves and the MT entity of the mobile relay accesses cell 2 of access network device 1, the mobile relay can send the location information again so that the management device can use the location information of cell 2 where the mobile relay is located. Assign TAC#3 to the mobile relay. If the mobile relay moves later, if it moves to a cell of access network device 1 that is different from cell 2, the mobile relay can resend the location information. This solution is similar to the solution provided in steps 514 to 520, and no longer Repeat. Through this solution, during the movement of the mobile relay, the TAC of the mobile relay's cell will also be dynamically updated, so that the network side can determine the location of the mobile relay based on the TAC of the mobile relay accessed by the terminal device. Then the current location of the terminal device can be determined more accurately.

Please refer to Figure 5b below. In Figure 5b, the mobile relay is moved out of the coverage of the current access network device, that is, the mobile relay is moved from the access network device one to the access network device two. That is, in the example shown in Figure 5b, the host base station of the mobile relay changes.

As shown in Figure 5b, the method includes:

Step 601: The mobile relay receives the broadcast message a1 from access network device one.

Step 602: The MT entity of the mobile relay performs cell selection and selects cell 1 for access.

Step 603: The MT entity of the mobile relay establishes an RRC connection with the access network device.

Step 604: The MT entity of the mobile relay sends a registration request message to the core network device.

Step 608: The management device determines the TAC #2 corresponding to the location information 1 of the mobile relay based on the location information 1 carried in the message a2.

Step 609: The management device may send a response message to message a2 to the mobile relay. The response message to message a2 carries cell configuration information, and the cell configuration information includes TAC#2.

Step 610: The DU entity of the mobile relay sends message a3 to the access network device 1 currently accessed by the MT entity of the mobile relay. The message a3 is used to request activation of the cell of the mobile relay. Message a3 can carry TAC#2.

Step 611: The access network device sends TAC#2 to the core network device.

Step 612: The access network device sends a response message of message a3 to the DU entity of the mobile relay.

Step 613: The mobile relay sends broadcast message a4.

Steps 601 to 613 included in Figure 5b are the same as steps 501 to 513 included in Figure 5a and will not be described again.

Step 614: The MT entity of the mobile relay receives the broadcast message a8.

The broadcast message a8 includes at least one of the TAC of cell 3 of access network device 2, the identity of cell 3, or the identity of access network device 2.

The mobile relay may be in a moving state. When the mobile relay moves from cell 1 of access network device 1 to cell 3 of access network device 2, the mobile relay may receive broadcast message a8. Then the mobile relay needs to perform cell selection again. For example, cell 3 can be selected as a new cell, and the mobile relay can access cell 3.

It is worth noting that when the MT entity of the mobile relay switches from access network device 1 to access network device 2, the MT entity of the mobile relay may be in the RRC connected state. The MT entity of the mobile relay in the RRC connected state switches from the cell of the access network device one to the cell of the access network device two, and establishes an RRC connection with the access network device two. This step is not shown in Figure 5b.

Step 615: The mobile relay determines that the mobile relay has moved.

For the relevant content of step 615, please refer to the relevant description of step 515, which will not be described again.

Step 616: The mobile relay sends message a9 to the management device. The message a9 includes the location information 3 of the mobile relay.

The location indicated by the location information 3 of the mobile relay carried in message a9 is the location of the mobile relay after movement. After the movement, the mobile relay is within the coverage of cell 3 of access network device 2.

For the relevant content of step 616, please refer to the relevant description of step 412, which will not be described again.

Step 617: The management device determines the TAC #4 corresponding to the location information 3 of the mobile relay based on the location information 3 carried in the message a9.

For the relevant content of step 617, please refer to the relevant introduction of the management device determining the first TAC, and will not be described again.

Step 618: The management device may send a response message to message a9 to the mobile relay, where the response message to message a9 carries TAC#4.

Correspondingly, the mobile relay receives the response message of message a9 from the management device.

TAC#4 is used as the TAC of the cell serving as a mobile relay. For the relevant content of step 618, please refer to the relevant description of step 413, which will not be described again.

Similarly, message a9 may be sent by the MT entity of the mobile relay, and the response message to message a9 may be sent by the management device to the MT entity of the mobile relay. Message a9 may also be sent by the DU entity of the mobile relay, and the response message of message a9 may also be sent by the management device to the DU entity of the mobile relay. For relevant content, please refer to the above description and will not be repeated again.

Step 619: The DU entity of the mobile relay sends message a10 to the access network device 2 currently accessed by the MT entity of the mobile relay. The message a10 is used to request activation of the cell of the mobile relay. Message a10 may include TAC#4.

For the content of step 619, please refer to the relevant content of the aforementioned step 403, and will not be described again.

Step 620: Access network device 2 sends TAC#4 to the core network device.

In step 620, the access network device 2 may also send other information to the core network device, such as information in the activated cell configuration information of the mobile relay. For the relevant content of step 620, please refer to the relevant description of step 404. TAC#4 can be carried in the target configuration information, and the relevant content will not be described again here.

Step 621: Access network device 2 sends a response message of message a10 to the DU entity of the mobile relay.

For the content of step 621, please refer to the relevant content of step 405, and will not be described again.

Step 622: The mobile relay sends the broadcast message a11.

For example, the DU entity of the mobile relay sends the broadcast message a11 or the MT entity of the mobile relay sends the broadcast message a11. This application is not limited. For relevant content, please refer to the foregoing description and will not be repeated here.

In a possible implementation, the broadcast message a11 includes TAC#4.

For the content of step 622, please refer to the relevant content of the aforementioned step 406, and will not be described again.

It can be seen from the embodiment shown in Figure 5b that the MT entity of the mobile relay accesses cell 1 of access network device 1, and the management device allocates TAC#2 to the mobile relay based on the location information of cell 1 where the mobile relay is located. . When the mobile relay moves and the MT entity of the mobile relay accesses cell 3 of access network device 2, the mobile relay can send the location information again so that the management device can use the location information of cell 3 where the mobile relay is located. Assign TAC#4 to the mobile relay. If the mobile relay moves later, if it moves to an access network device different from the access network device 2, the mobile relay can resend the location information. This solution is similar to the solution provided in steps 614 to 622, and is no longer Repeat. If the mobile relay subsequently moves again and moves to another cell of the access network device 2, the mobile relay can resend the location information. This solution is similar to the solution provided in steps 514 to 520 and will not be described again. Through this solution, during the movement of the mobile relay, the TAC of the mobile relay's cell will also be dynamically updated, so that the network side can determine the location of the mobile relay based on the TAC of the mobile relay accessed by the terminal device. Then the current location of the terminal device can be determined more accurately.

In the above step 201, the management device can also obtain the location information of the mobile relay through various other methods. In a possible implementation, the core network device sends the location information of the mobile relay to the management device. Correspondingly, the management device receives the location information of the mobile relay from the core network device. Compared with the solution in which the mobile relay sends location information, the solution in which the management device obtains the location information of the mobile relay from the core network device can reduce the number of times the mobile relay sends location information to the management device, thereby saving mobile relay power.

For example, the management device can subscribe to the core network device for the location information of the mobile relay, and then the core network device can send the location information of the mobile relay to the management device. For example, a message for subscribing to the location information of the mobile relay can be sent to the core network device. For example, the message used to subscribe to the location information of the mobile relay may include indication information indicating the MT entity of the mobile relay. The indication information may be the identity of the MT entity, and the identity of the MT entity may be a general public user. Identifier (Generic Public Subscription Identifier, GPSI), User Permanent Identifier (Subscription Permanent Identifier, SUPI), Mobile Subscriber International Integrated Services Digital Network Identifier (mobile subscriber international ISDN/PSTN number, MSISDN), etc. Among them, ISDN is the abbreviation of integrated service digital network (ISDN). PSTN is the abbreviation of public switched telephone network (PSTN). The core network device may store information indicating the mobile relay The corresponding relationship between the indication information of the MT entity and the location information of the mobile relay (such as the location information of the MT entity of the mobile relay). Then, the core network device can use the indication for instructing the MT entity of the mobile relay to The information queries the location information of the mobile relay from the corresponding relationship, and then the location information of the mobile relay can be sent to the management device.

As another example, the message used to subscribe to the location information of a mobile relay may include indication information (such as the identity of the DU entity) used to indicate the mobile relay's DU entity, and the core network device may store the information used to indicate the mobile relay's location information. The corresponding relationship between the indication information of the DU entity of the relay and the location information of the mobile relay (such as the location information of the MT entity of the mobile relay). Then, the core network device can use the DU for indicating the mobile relay to The entity's indication information queries the location information of the mobile relay from the corresponding relationship, and then the location information of the mobile relay can be sent to the management device. In this way, the management device can configure the TAC for the cell of the mobile relay based on the obtained location information of the mobile relay.

For another example, the management device can query the core network device for the location information of the mobile relay. For example, the management device can periodically query the core network device for the location information of the mobile relay.

Based on the content shown in at least one of the above-mentioned FIG. 1a, FIG. 1b, FIG. 1c, FIG. 1d, or FIG. 2 and other content, FIG. 6 exemplarily shows a flow chart of yet another cell information configuration method. The embodiment shown in FIG. 6 can be regarded as an extended embodiment of the embodiment shown in FIG. 6 .

As shown in Figure 6, the method includes:

Step 701: The mobile relay sends the identification of the mobile relay and/or the indication information used to trigger the management device to subscribe to the location information of the mobile relay to the management device.

Correspondingly, the management device receives the identification of the mobile relay from the mobile relay and/or the indication information used to trigger the management device to subscribe to the location information of the mobile relay.

Similarly, the identity of the mobile relay and/or the indication information used to trigger the management device to subscribe to the location information of the mobile relay may be sent by the MT entity of the mobile relay, or may be sent by the DU entity of the mobile relay. For relevant content, please refer to the above description and will not be repeated again.

The identity of the mobile relay can be used when the subsequent management device subscribes to the core network device for the location information of the mobile relay. For example, the management device can send the identity of the mobile relay to the core network device NEF so that NEF can query the mobile relay identity. The corresponding AMF, thereby subscribing to the AMF for the location information of the mobile relay. The AMF side can store the correspondence between the identity of the MT entity of the mobile relay and the location information of the mobile relay, and then the AMF can query the location information of the mobile relay based on the identity of the MT entity from the correspondence. The identity of the mobile relay can be understood as the identity of the MT function of the mobile relay that has successfully accessed the network, such as the subscriber permanent identifier (SUPI), mobile subscriber international ISDN/PSTN number , MSISDN) etc. Among them, ISDN is the abbreviation of integrated service digital network (ISDN). PSTN is the abbreviation of public switched telephone network (PSTN).

In a possible implementation, the indication information used to trigger the management device to subscribe to the location information of the mobile relay may be an identification of the mobile relay. For example, if the identifier of the mobile relay is specially set, the management device can determine that the mobile relay has mobility capabilities based on the identifier of the mobile relay. Rules can be preset on the management device side: for relay devices with mobile capabilities, location information of such relay devices needs to be subscribed. In this case, the management device determines that the mobile relay has mobility capabilities based on the received identification of the mobile relay, and then the management device subscribes to the core network device for the location information of the mobile relay. In this case, step 701 can also be replaced by: the mobile relay sends the identification of the mobile relay to the management device.

In another possible implementation, the location information used to trigger the management device to subscribe to the mobile relay in the embodiment of the present application is The indication information may be: information used to indicate that the type of mobile relay is a relay device with mobility capabilities. Rules can be preset on the management device side: for relay devices with mobile capabilities, location information of such relay devices needs to be subscribed. In this case, the management device determines that the mobile relay has mobility capability based on the received information indicating that the type of the mobile relay is a relay device with mobility capability, and then the management device subscribes to the core network device for the mobility capability. location information.

The information used to indicate that the type of the mobile relay is a relay device with mobility capabilities can be implemented in a variety of ways. For example, the information used to indicate that the type of the mobile relay is a vehicle-mounted relay device type, and then For example, it may be information used to indicate that the type of mobile relay is a type of relay device deployed on a drone. Another example may be information used to indicate that the type of mobile relay is a type of relay device deployed on an aircraft. Since vehicles, drones, or aircraft have mobility capabilities and are usually in a mobile state, relay devices deployed on such vehicles can be regarded as relay devices with mobility capabilities.

In another possible implementation, relay devices without mobility capabilities may be called non-mobile relays. When the management device configures TAC for such non-mobile relays, it may be configured based on the location information of the non-mobile relays. TAC may also not be configured based on the location information of the non-mobile relay. When the management device determines that the relay device belongs to a non-mobile relay (for example, the management device does not receive the location information indication information from the relay device that is used to trigger the management device to subscribe to the mobile relay), it determines that the relay device belongs to a non-mobile relay; For another example, if the message sent by the relay device to the management device requesting to configure the cell configuration information of the relay device does not carry the location information indication information used to trigger the management device to subscribe to the mobile relay, it is determined that the relay device belongs to a non-mobile relay. ), and there is no need to configure TAC based on the location information of the non-mobile relay, the management device does not need to subscribe to the location information of the non-mobile relay, thereby saving signaling overhead.

In this application, there are many ways for the management device to determine that the relay device is a non-mobile relay. For example, if the management device does not receive the location information indication information from the relay device to trigger the management device to subscribe to the mobile relay, then it determines that the relay device is a non-mobile relay. The relay equipment is a non-mobile relay. For another example, if the message sent by the relay device to the management device requesting to configure the cell configuration information of the relay device does not carry the location information indication information used to trigger the management device to subscribe to the mobile relay, it is determined that the relay device belongs to a non-mobile relay. .

The mobile relay may subscribe to the core network device for the location information of the mobile relay upon receiving indication information for triggering the management device to subscribe to the location information of the mobile relay. In another possible implementation, the management device may not subscribe to the core network device for the location information of the mobile relay if the management device does not receive the instruction information for triggering the management device to subscribe to the location information of the mobile relay. This can reduce the signaling consumption caused by subscribing to location information of non-mobile relays.

It is worth noting that step 701 is an optional step and may or may not be executed. Figure 6 takes the mobile relay execution step 701 as an example.

Step 702: The management device sends a first subscription request message to the NEF. The first subscription request message is used to subscribe to the location information of the mobile relay.

For example, the first subscription request message may carry the identifier of the mobile relay and the subscription event identifier, where the subscription event identifier is used to indicate that this subscription event includes the location information of the subscribed mobile relay.

In a possible implementation, the management device may determine the subscription event identifier according to the preset movement range. It can also be understood that the subscription event identifier can indicate the type of location information that the management device needs to subscribe to.

In a possible implementation, the type of location information that the management device needs to subscribe to may be associated with a preset movement range. For example, the type of location information that the management device needs to subscribe to can be one or more items included in the preset movement range. One or more types of location information corresponding to the content.

For example, the preset mobility range includes: the TAC of the cell accessed by the mobile relay changes. Then the type of location information that the management device needs to subscribe to may include the TAC of the cell accessed by the mobile relay.

For another example, the preset mobility range includes: changes in the TAC of the cell to which the mobile relay is connected, changes to the cell identity of the cell to which the mobile relay is connected, and changes to the access network to which the mobile relay is connected. Equipment changes. Then, the type of location information that the management device needs to subscribe to may include at least one of the TAC of the cell accessed by the mobile relay, the cell identity, or the access network device identity.

Step 703: NEF sends a second subscription request message to AMF. The second subscription request message is used to subscribe to the location information of the mobile relay.

The NEF may query the UDM for the AMF serving the mobile relay according to the identifier of the mobile relay, and then send the second subscription request message to the AMF.

The second subscription request message may carry the identifier of the mobile relay and the subscription event identifier, where the subscription event identifier is used to indicate that this subscription event includes the location information of the subscribed mobile relay.

Step 704: AMF determines the location information of the mobile relay.

The location information of the mobile relay determined by the AMF comes in many forms. For example, the location information of the mobile relay determined by the AMF may include the TAC of the cell that the mobile relay accesses, the identity of the cell that the mobile relay accesses, or the mobile relay's location information. At least one of the identifiers of the access network equipment for relay access. The TAI in the embodiment of this application may include the TAC and the public land mobile network (public land mobile network, PLMN) identifier, or it may also be understood that the TAC is included in the TAI.

In a possible implementation, the subscription event identifier carried in the second subscription request message may indicate the type of location information that the management device needs to subscribe to. The AMF can feed back to the management device location information that matches the type of location information that the management device needs to subscribe to based on the subscription event identifier. For example, the location information of the mobile relay subscribed by the management device includes the identity of the cell that the mobile relay accesses. Then the location information of the mobile relay determined by the AMF also includes the identity of the cell that the mobile relay accesses. Then the mobile relay can be The identification of the accessed cell is sent to the management device.

The subscription event identifier in the embodiment of this application may not indicate the type of location information that the management device needs to subscribe to. In this case, the AMF can notify the management device of the queried location information of the mobile relay.

Step 705: The AMF sends a first notification message to the management device. The first notification message carries the location information 4 of the mobile relay.

In a possible implementation, after the AMF receives the subscription request message (such as the second subscription request message) sent by the management device through NEF, the AMF can send the location information 4 of the mobile relay to the management device through step 705.

In step 705, the AMF may send the first notification message to the management device through NEF. For example, the AMF may first send the notification message to NEF, and then the NEF may transparently transmit or forward the first notification message to the management device.

Step 706: The management device determines TAC#5 corresponding to the location information 4.

For the relevant content of step 706, please refer to the relevant content of the management device determining the TAC of the mobile relay cell based on the location information, and will not be described again.

Step 707: The management device sends TAC#5 to the mobile relay. TAC#5 is determined based on the location information 4 of the mobile relay. TAC#5 is used as the TAC of the cell serving as a mobile relay.

Similarly, TAC#5 may be sent by the management device to the MT entity of the mobile relay, or may be sent by the management device to the DU entity of the mobile relay.

For the relevant content of step 707, please refer to the relevant content of the aforementioned step 202.

Since the mobile relay may move, after step 705, step 708 may also be included:

Step 708: AMF determines that the mobile relay has moved.

In a possible implementation, since the AMF receives the second subscription request message, that is, the management device subscribes to the AMF for the location information of the mobile relay, the AMF determines whether the mobile relay has moved. It can also be understood as step 703 as a prerequisite for step 708.

In another possible implementation, if the management device does not subscribe to the AMF for the location information of the mobile relay, the AMF does not need to determine whether the mobile relay has moved. It can be seen that in this embodiment, the AMF does not determine whether the mobile relay has moved for all mobile relays, thereby reducing the workload of the AMF.

In a possible implementation, in step 708, the AMF needs to determine that the location movement range of the mobile relay satisfies the preset movement range.

The AMF determines whether the movement of the mobile relay satisfies the preset movement range based on the obtained information.

For example, the preset movement range includes: the identity of the cell accessed by the mobile relay changes. The mobile relay moves from the second cell of the first access network device to the first cell of the first access network device. When the mobile relay accesses the second cell of the first access network device, the first access network device Send the identifier of the second cell accessed by the mobile relay to the AMF. When the mobile relay accesses the first cell of the first access network device, the first access network device sends the identifier of the first cell that the mobile relay accesses to the AMF. When the AMF determines that the identity of the cell accessed by the mobile relay is updated from the identity of the second cell to the identity of the first cell, the AMF determines that the location of the mobile relay has moved.

The AMF's determination of whether the movement of the mobile relay satisfies the preset movement range is similar to the previous solution for the mobile relay to determine whether the movement of the mobile relay satisfies the preset movement range, and will not be elaborated here. The difference is that the mobile relay obtains the TAC, cell identity, access network equipment, information of the geographical area where the mobile relay is located, or the moving distance of the mobile relay, and the AMF obtains this information. The methods may be somewhat different. The AMF can receive or query the TAC, cell identity, access network equipment, information of the geographical area where the mobile relay is located, or the moving distance of the mobile relay. The embodiments of this application do not limit this.

It is worth noting that the situation in which the AMF determines that the movement of the mobile relay does not meet the preset movement range is similar to the above situation in which the mobile relay determines that the movement of the mobile relay does not meet the preset movement range, and will not be described again here.

Step 709: The AMF sends a second notification message to the management device. The second notification message carries the location information 5 of the mobile relay.

In a possible implementation, since the MF receives the second subscription request message, that is, the management device subscribes to the AMF for the location information of the mobile relay, the AMF can perform step 709 when it determines that the mobile relay has moved.

Since before step 709, the AMF determines that the mobile relay has moved, the location information 5 of the mobile relay carried by the AMF in the second notification message is the location information of the mobile relay after movement. The location information 5 of the mobile relay is different from the location information 4 of the mobile relay. It is worth explaining that the access network device corresponding to location information 4 and the access network device corresponding to location information 5 may be the same or different.

In another possible implementation, when the AMF determines that the location movement range of the mobile relay satisfies the preset movement range, the AMF executes step 709 to send the moved location information of the mobile relay to the management device. In another possible implementation, when the AMF determines that the location movement range of the mobile relay does not meet the preset movement range, for example, the mobile relay has not moved out of the current cell, the AMF may not send the location information of the mobile relay to the management device. , or attribute this situation to the situation where the mobile relay has not moved.

In step 709, AMF may send a second notification message to the management device through NEF. For example, AMF may first send The notification message is sent, and then the NEF transparently transmits or forwards the second notification message to the management device.

Step 710: The management device determines TAC#6 corresponding to the location information 5.

For the relevant content of step 710, please refer to the relevant content of the management device determining the TAC of the mobile relay cell based on the location information, and will not be described again.

In step 710, in a possible implementation, the management device may not determine whether the movement of the mobile relay satisfies the preset movement range. When the management device receives the location information 5, it can determine the TAC #6 corresponding to the location information 5.

In another possible implementation, the management device can also determine whether the movement of the mobile relay satisfies the preset movement range. For example, the management device receives the location information 5, and determines the TAC #6 corresponding to the location information 5 when it is determined that the movement of the mobile relay satisfies the preset movement range. For another example, when the management device receives location information 5 and determines that the movement of the mobile relay does not meet the preset movement range, it is not sure of the TAC#6 corresponding to the location information 5 and no longer notifies the mobile relay of TAC#6. .

The solution for the management device to determine that the mobile relay has moved is similar to the previous solution for the mobile relay to determine that the mobile relay has moved, and will not be elaborated here. The difference lies in the way in which the mobile relay obtains the TAC, cell identity, access network equipment, information on the geographical area where the mobile relay is located, or the moving distance of the mobile relay, and the management device. The methods of this information may be somewhat different. The management device may receive or query the TAC of the cell accessed by the mobile relay, cell identity, access network equipment, information about the geographical area where the mobile relay is located, or information about the mobile relay's location. Moving distance. The embodiments of this application do not limit this.

In another possible implementation, when the AMF determines that the movement of the mobile relay satisfies the preset movement range, the AMF sends location information to the management device, and when the AMF determines that the movement of the mobile relay does not meet the preset movement range , you do not need to send location information to the management device. In this case, the management device may not determine whether the movement of the mobile relay satisfies the preset movement range.

In another possible implementation, the AMF may not determine whether the movement of the mobile relay satisfies the preset movement range. In this case, the management device can determine whether the movement of the mobile relay satisfies the preset movement range.

In another possible implementation, the AMF may not determine whether the movement of the mobile relay meets the preset movement range, and notify the management device after obtaining the location information. In this case, the management device can perform the step of judging whether the movement of the mobile relay satisfies the preset movement range, and feeds back TAC#6 to the mobile relay when the movement of the mobile relay satisfies the preset movement range. If the relay's movement does not meet the preset movement range, TAC#6 will not be fed back to the mobile relay. The management device may also directly feed back TAC#6 to the mobile relay without performing the step of determining whether the movement of the mobile relay satisfies the preset movement range.

Step 711: The management device sends TAC#6 to the mobile relay. TAC#6 is determined based on the location information 5 of the mobile relay. TAC#6 is used as the TAC of the cell serving as a mobile relay.

Similarly, TAC#6 may be sent by the management device to the MT entity of the mobile relay, or may be sent by the management device to the DU entity of the mobile relay.

For the relevant content of step 711, please refer to the relevant content of the aforementioned step 202.

In the solution shown in Figure 6, step 707 can be used as a possible implementation of the above-mentioned step 202. In this case, TAC#5 is the above-mentioned first TAC. Step 711 can also be used as a possible implementation of the above-mentioned step 202. In this case, TAC#6 is the above-mentioned first TAC.

It is worth noting that the mobile relay may move one or more times in the future. When the AMF determines that the mobile relay has moved, the AMF can send the location information of the moved mobile relay to the management device again, so that the management device can move according to the The moved location information of the mobile relay configures a TAC for the mobile relay, thereby achieving the effect of dynamically configuring a TAC for the mobile relay based on the location information of the mobile relay.

It can be seen from the solution in Figure 6 that the management device can receive the location information of the mobile relay from the core network device in various scenarios. For example, after the AMF receives the second subscription request message, the AMF may send the location information of the mobile relay to the management device through step 705. For another example, after the AMF determines that the mobile relay has moved, the AMF may send the location information of the mobile relay to the management device through step 709. Step 705 and step 709 can be regarded as several possible implementations of the aforementioned step 201.

The solution provided in Figure 6 can also include other steps. For example, after obtaining the TAC from the management device, the mobile relay can also send the received TAC to the host base station. The mobile relay can also send the received TAC to the host base station according to the TAC obtained from the management device. Send a broadcast message.
