The following describes in detail, by means of specific embodiments and application scenarios thereof, a method, an apparatus, a device, and a medium for configuring handover information of an IAB host node provided in the embodiments of the present application with reference to the accompanying drawings.

Example 1

Fig. 1 is a flowchart of a handover information configuration method of an IAB host node according to an embodiment of the present application. As shown in fig. 1, the method specifically comprises the following steps:

s101, obtaining the topology structure of the current IAB host node and obtaining the topology structure of the adjacent IAB host node.

Firstly, the usage scenario of the present solution may be a scenario in which, when an IAB hosting node needs to be switched, a current IAB hosting node searches for a target IAB hosting node and obtains configuration information of the target IAB hosting node.

Based on the above usage scenario, it can be appreciated that the execution subject of the present application may be the current IAB host node, which is not limited in this way.

In this scenario, the method is performed by the current IAB host node.

The current IAB-hosting node may be an IAB-hosting node to which the device is currently connected, may be a plurality of different types of devices, and may include, for example:

1. 4G/5G base station: the 4G/5G base station generally has higher processing capacity and network capacity, can play the role of an IAB host node, simultaneously provides access and backhaul functions, and realizes integrated network service.

2. Router/switch: routers and switches typically have good network management and control capabilities, can act as IAB hosting nodes to handle network traffic, and provide access and backhaul functionality.

3. Multimedia gateway: multimedia gateways typically have audio and video processing capabilities, can act as IAB host nodes to handle multimedia traffic and provide access and backhaul functions.

4. Gateway of internet of things: the internet of things gateway generally has better internet of things protocol support and data management capability, can be used as an IAB host node to process internet of things traffic, and provides access and return functions.

In this scenario, the topology may refer to a physical layout of various devices such as computers connected to each other by a transmission medium, and refers to a geometry formed during the interconnection process, which can represent network configurations of network servers and workstations and connections between each other. The IAB hosting node topology may be a tree network topology, where individual IAB nodes are hierarchically connected, where the higher the position, the more reliable the node is. I.e., the IAB home node is at the highest position and the IAB intermediate node is at the lower layer position of the IAB home node. In the tree structure, no loop is generated between two nodes in all nodes, and all paths can carry out bidirectional transmission. The topology structure can embody an IAB intermediate node under the IAB host node and the connection relation between the IAB host node and the IAB intermediate node.

The IAB hosting node may obtain the topology of the current IAB hosting node and the neighboring IAB hosting nodes by:

1. an IP address or domain name of the IAB host node is determined.

2. And performing route tracking on the IAB host node by using a network tool such as Traceroute and the like to acquire the route path information of the host node.

3. For each router, the SNMP protocol (Simple Network Management Protocol ) is used to obtain other device information of its topology and connections. SNMP can obtain information of network devices through MIB (Management Information Base ).

4. And establishing a network topological graph by using the topological structure and the equipment information, and marking the IAB host node and other connected equipment, thereby obtaining the topological structure of the IAB host node and the IAB intermediate node.

S102, determining an edge IAB node according to the coverage range of the current IAB host node topological structure.

The coverage area of the IAB host node topology may be the range of the IAB intermediate nodes included in the IAB host node topology and the area formed by all the included IAB intermediate nodes. For example, there are 3 IAB intermediate nodes in the IAB host node topology, and these 3 IAB intermediate nodes may form a circular area with a radius of 100 meters, and then the coverage area of the IAB host node topology is a circular area with a radius of 100 meters.

An edge IAB node may be a node in the IAB hosting node topology coverage that is at an edge location, i.e. physically closest to the terminal device. The function of the edge IAB node is to process the data transmitted from the terminal device, process and analyze the data, and send the processed data to the IAB host node for further processing and storage.

The coverage of the IAB host node topology may be determined by measuring the radio signal strength and transmission distance of the IAB host node. Areas of lesser coverage may then be determined and considered as edge IAB node locations. Specifically, a standard range finder or a radar range finder or other device may be used to measure the distance between the IAB host node and the comprised IAB intermediate node to determine the coverage of the IAB host node topology. These devices typically use radio waves or laser beams or the like to measure distance and can provide highly accurate measurement results.

S103, identifying whether the coverage areas of the edge IAB node and the adjacent IAB host node topological structure meet preset conditions or not.

When the coverage area between the edge IAB node and the adjacent IAB host node topology structure is within a certain distance, the adjacent IAB host node meeting the preset condition can be considered, and if a plurality of adjacent IAB host nodes meeting the preset condition exist, the adjacent IAB host node closest to the adjacent IAB host node is selected. For example, it may be provided that the preset condition is satisfied when the distance between the edge IAB node and the coverage of the neighboring IAB host node topology is within 100 meters, and the preset condition may be pre-stored in the memory chip of the current IAB host node.

When determining the edge IAB node, the location of the edge IAB node may be obtained by a GPS device, in particular expressed in terms of (latitude, longitude), and then the coverage of the neighboring IAB host node topology and the distance between the edge IAB node and the coverage of the neighboring IAB host node topology are measured using a standard range finder or radar range finder or the like. After the distance between the two is obtained, the distance between the two can be compared with a preset condition stored in the current IAB host node in advance, so as to identify whether the coverage range of the topological structures of the edge IAB node and the adjacent IAB host node meets the preset condition.

On the basis of the above technical solutions, optionally, identifying whether the coverage areas of the edge IAB node and the adjacent IAB host node topology structure meet a preset condition includes:

or alternatively, the process may be performed,

Or alternatively, the process may be performed,

In this scheme, the coverage of the edge IAB node refers to the coverage of the wireless signal, that is, the coverage of the wireless signal of the edge IAB node. The coverage of the topology of the neighboring IAB host nodes refers to the radio signal coverage between them, i.e. the range that radio signals between neighboring IAB host nodes can cover.

If there is an overlapping portion between the coverage of the edge IAB node and the coverage of the topology of the neighboring IAB host node, or if the distance is within a preset distance, it indicates that the wireless signals between the nodes can cover each other, and communication can be performed. Specifically:

if the overlapping portion exists, the wireless signal representing the edge IAB node can be covered inside the topological structure of the adjacent IAB host node, or the wireless signal of the adjacent IAB host node can be covered inside the coverage of the edge IAB node, and communication can be performed, and the preset condition is determined to be met.

If the distance is within the preset distance, which means that the distance between the edge IAB node and the adjacent IAB host node does not exceed the preset distance, communication can be performed, and the preset condition is determined to be met.

These conditions are important judgment conditions in edge computation and network communication, and can be used for determining the communication relationship and topology structure between nodes so as to realize efficient data transmission and network management. Specifically, whether the preset condition is satisfied may be determined using the following code:

if (overlapping part of coverage of edge IAB node and coverage of adjacent IAB host node topology has a distance within a preset distance) {

The corresponding operation is executed if the preset condition is met

} else {

The corresponding operation is executed if the ratio of the input data to the output data is not satisfied with the preset condition

}

If a traffic road exists between the coverage area of the edge IAB node and the coverage area of the topology structure of the adjacent IAB host node, it can be considered that, on the traffic road, even if the wireless signal of the edge IAB node cannot cover the inside of the topology structure of the adjacent IAB host node, the wireless signal of the adjacent IAB host node can cover the inside of the coverage area of the edge IAB node. Thus, communication between the edge IAB node and the neighboring IAB host node may be via a traffic road.

If no traffic road exists, the communication between the edge IAB node and the adjacent IAB host node cannot be directly carried out, and the communication can be established through the transfer of other nodes. This increases the latency and complexity of the communication and may reduce network performance. Therefore, if there is no traffic road, the preset condition cannot be satisfied.

If there is an isolation barrier between the coverage of an edge IAB node and the coverage of the neighboring IAB host node topology, this means that there may be an occlusion between the edge IAB node and the neighboring IAB host node, resulting in a blocked transmission of wireless signals. This causes interference or interruption of communication between the nodes, and thus the preset condition cannot be satisfied.

Isolation obstructions may include buildings, high walls, mountains, etc., which may block the transmission of wireless signals such that communication between nodes may not be established or signal quality may be poor. Therefore, if there is an isolation barrier between the coverage of the edge IAB node and the coverage of the neighboring IAB host node topology, the preset condition cannot be satisfied.

In the scheme, the specific content of the preset condition is set, so that the target IAB host node can be found out more quickly, and the current IAB host node can acquire the configuration information of the target IAB host node more quickly and accurately. The method can lead the edge IAB node to preprocess the switching of the IAB host node, avoid the congestion problem caused by information synchronization during actual connection, and improve the switching speed of the IAB host node.

S104, if yes, identifying a handover target IAB host node of the edge IAB node; wherein the handover target IAB hosting node is at least one of the neighboring IAB hosting nodes.

If the adjacent IAB host node meeting the preset condition exists, the adjacent IAB host node is determined to be the handover target IAB host node. The IAB host node information may be stored in a memory chip of the IAB intermediate node, and specifically may include information such as an IAB host node number, a location, and a coverage area. The current IAB host node may achieve the purpose of determining a handover target IAB host node by identifying a number of neighboring IAB host nodes.

S105, acquiring configuration information of the handover target IAB host node.

The configuration information of the handover target IAB host node may include:

1. IP address: each IAB host node requires a unique IP address for identification and communication over the network. The IAB-hosting node may be assigned a static IP address or a dynamic IP address.

2. Subnet mask: the subnet mask is used to define a range of network addresses and the number of IP addresses assigned to each device. It decides which addresses in the network can be routed to other networks.

3. Gateway: a gateway is a device, such as a router or switch, that connects to other networks. It allows the IAB-hosting node to communicate with other networks.

4. DNS (Domain Name System ) server: DNS servers are devices that convert domain names into IP addresses. The IAB host node needs to know which DNS server can be used in order to perform domain name resolution when needed.

5. And (3) safety setting: the IAB-hosting node may have security settings, such as firewalls, VPNs, authentication and encryption, etc., to protect the network from unauthorized access and attacks.

6. Hardware and software configuration: the IAB host node may have specific hardware requirements such as processors, memory, and storage. Furthermore, they may require specific software configurations, such as operating systems, network services, and applications, among others.

The following steps are generally required to obtain configuration information of the handover target IAB host node:

1. determining the position and network topology of the IAB host node: before the configuration information is obtained, the location of the IAB host node and the network topology in which it is located need to be known. May be obtained by querying an online map tool or GIS (Geographic InformationSystem or Geo-information system) software.

2. Acquiring and recording configuration information: the current IAB hosting node may be given query authority in advance, and then configuration information of the IAB hosting node may be automatically queried, including an IP address, a subnet mask, a gateway, a DNS server, security settings, and hardware and software configurations, etc., which may be obtained by referring to a network document.

And S106, the configuration information is sent to the edge IAB node, and the edge IAB node is used for backing up the configuration information.

To send configuration information of the handover target IAB host node to the edge IAB node, the following steps may be performed:

1. exporting configuration information into a file: on the handover target IAB hosting node, the configuration information is exported as a file, e.g. in CSV, XML, JSON, etc. This may be accomplished using command line tools, network management software, or third party tools.

2. Uploading the file to a cloud storage or file sharing service: once the configuration file is exported, the file needs to be uploaded into a cloud storage or file sharing service so that the edge IAB node can be downloaded and used. Common cloud storage or file sharing services include AmazonS3, google Drive, microsoft onedrive, dropbox, and the like.

3. Transmitting a shared link or grant to the edge IAB node: once the configuration file is uploaded, a shared link or authorization needs to be sent to the edge IAB node so that the edge IAB node can access and download the file. The shared links or authorizations may be sent using email, instant messaging, or other communication tools.

4. The edge IAB node downloads and imports the configuration file: the edge IAB node may download and import a configuration file using the same file format to backup configuration information of the handover target IAB hosting node. Instructions and support may be provided to ensure that the edge IAB node properly imports and uses the configuration file.

The edge IAB node may backup configuration information of the handover target IAB home node by:

1. downloading a configuration file of the handover target IAB host node: the edge IAB node needs to download its configuration file from the handover target IAB hosting node.

2. Importing a configuration file: the edge IAB node needs to import the configuration file of the handover target IAB hosting node into its local device. The manner in which the configuration file is imported depends on the file format and the device type. For example, for a Windows operating system, a registry editor or group policy management editor may be used to import configuration files. For Linux or other operating systems, the import may be performed using a profile management tool or script.

3. Checking the configuration file: once the configuration file is imported, the edge IAB node needs to check if the information in the configuration file is correct. In particular, the edge IAB node needs to check if the information such as the IP address, subnet mask, gateway, DNS server, and security settings are correct.

4. Backup configuration file: once the information in the configuration file is confirmed to be correct, the edge IAB node needs to backup it to local or cloud storage. The backup configuration file may ensure that configuration information may be restored in time when a device failure, data loss, or other problem occurs.

Based on the above technical solutions, optionally, after sending the configuration information to the edge IAB node for the edge IAB node to backup the configuration information, the method further includes:

establishing a monitoring task;

In this solution, the monitoring task of monitoring whether the target IAB hosting node has a configuration change event may be a network management task, which is usually executed by a network management system or device. The main purpose of the task is to monitor the configuration change event of the target IAB host node and acquire and apply the changed configuration information in time so as to ensure the normal operation and the high-efficiency performance of the network.

The monitoring task of establishing whether the monitoring switching target IAB host node has a configuration change event needs to execute the following steps:

1. a listening parameter is determined. Parameters to be monitored, such as network topology changes, node state changes, configuration parameter changes, and the like, are determined and matched with the actual network environment.

2. A listener is set. And writing a monitoring program, including acquiring monitoring parameters, judging whether a configuration change event exists, acquiring configuration change information and the like.

The listening period may refer to a time interval for the listening task to be performed, which is typically preset by the network management system or device, and may be a different time interval such as a few seconds or a few minutes.

The configuration change event of the handover target IAB host node may refer to that a configuration change, such as a change of information, such as a routing table, an IP address, and a port, occurs in the handover target IAB host node, and these changes may affect aspects, such as a network topology, a data transmission path, and communication efficiency.

According to the monitoring period of the monitoring task, monitoring whether the configuration change event exists in the target IAB host node or not, and executing the following steps:

1. a listening period is determined.

2. And starting a monitoring task. And starting a monitoring task and monitoring the handover target IAB host node when the monitoring period starts so as to detect whether a configuration change event exists.

3. Configuration change information is acquired. If a configuration change event exists, the changed configuration information is immediately acquired, wherein the configuration information comprises information such as node names, addresses, services, routing tables and the like.

4. Configuration change information is applied. And updating relevant configuration parameters, routing tables and other information according to the acquired configuration information, and applying the information to a network management system or equipment so as to ensure the normal operation of the network.

5. And stopping monitoring the task. And stopping the monitoring task when the monitoring period is ended, and waiting for the arrival of the next monitoring period.

When a configuration change event is identified, issuing a configuration change synchronization request to the handover target IAB host node requires the following steps to be performed:

1. a configuration change event is confirmed. In the monitoring task, if a configuration change event exists in the handover target IAB host node, whether the event exists is confirmed, and changed configuration information is acquired.

2. A synchronization request is constructed. And constructing a synchronous request according to the acquired changed configuration information, wherein the synchronous request comprises a protocol type of the synchronous request, an address and a port number of a target IAB host node, contents and formats of the synchronous request and the like.

3. And sending a synchronous request. The constructed synchronization request is sent to the target IAB host node using a network transport protocol (e.g., TCP/IP protocol) and waits for its response.

4. The synchronization response is processed. If the target IAB host node accepts the synchronization request and returns a response, the response data needs to be processed, including parsing the response data, updating local configuration information, routing tables, and the like.

5. And feeding back a synchronization result. According to the processing result of the synchronization request, the synchronization result can be fed back to a network management system or other related equipment, and corresponding subsequent processing is performed.

In the scheme, the configuration change event is automatically monitored according to the monitoring task, and the configuration change synchronous request is sent to the switching target IAB host node according to the configuration change event, so that the switching target IAB host node can preprocess the switching of the IAB host node, the congestion problem caused by information synchronization is avoided in actual connection, and the switching speed of the IAB host node is improved.

According to the technical scheme provided by the embodiment, the topology structure of the current IAB host node is obtained, and the topology structure of the adjacent IAB host node is obtained; determining an edge IAB node according to the coverage range of the current IAB host node topological structure; identifying whether the coverage areas of the edge IAB node and the adjacent IAB host node topological structure meet preset conditions or not; if yes, identifying a handover target IAB host node of the edge IAB node; wherein the handover target IAB hosting node is at least one of the neighboring IAB hosting nodes; acquiring configuration information of the handover target IAB host node; and sending the configuration information to the edge IAB node for the edge IAB node to backup the configuration information. By the method for configuring the switching information of the IAB host node, the configuration information of the target IAB host node can be obtained in advance before the IAB host node is switched, so that the congestion problem caused by information synchronization is avoided during actual connection, and the switching speed of the IAB host node is further improved.

S207, identifying whether the edge IAB node is connected with the UE.

The UE (User Equipment) may be a radio device, which refers to a terminal device in a mobile communication system, such as a mobile phone, a tablet computer, etc. In mobile communication networks such as LTE and 5G, a UE is one of the key devices for communication with a base station.

To identify whether an edge IAB node is connected to a UE, the following steps may be performed:

1. look at the physical connection of the edge IAB node: it is checked whether the network interface of the edge IAB node has been properly connected to the network device (e.g. switch, router, etc.) and whether the network device is functioning properly.

2. Viewing the management interface of the edge IAB node: the connection state of the node is checked using a management tool of the edge IAB node (such as a Web interface or a command line interface). If the UE is already connected correctly, the relevant information should be visible in the management interface.

3. Detection using a network tool: the edge IAB node is tested using a network tool (e.g., ping, traceroute, etc.) to see if it can communicate with the node. If communication with the node is possible, it is indicated that the UE is already connected.

4. Checking the connection state of the base station: if the edge IAB node is a base station in a mobile communication system, it is possible to determine whether the UE is connected by checking the connection state of the base station. The connection status of the base station may be checked using a base station management tool or command line interface.

The UE may roam in the network and thus may sometimes take some time to confirm whether the UE is connected to an edge IAB node. In addition, if the edge IAB node connects a plurality of UEs, detection of each UE is required.

On the basis of the above technical solutions, optionally, after identifying whether the edge IAB node is connected to a UE, the method further includes:

In this solution, the second handover condition may be that the UE is connected to the edge IAB node after being disconnected from the handover target IAB host node, but needs to be reconnected to the handover target IAB host node.

To identify whether the UE was previously connected to the handover target IAB hosting node before being connected to the edge IAB node, it may be performed by:

1. looking up the connection history of the UE: the connection history of the UE may be reviewed to determine whether the UE has connected to the handover target IAB hosting node. These histories may be kept in log files of the UE, the edge IAB node or the network device, and information may be obtained by examining these log files.

2. Checking pre-stored configuration information of the UE: if the UE has pre-stored configuration information for the handover target IAB hosting node, it may be determined whether the UE has connected to the node by checking the pre-stored configuration information. If the configuration information already exists, it is indicated that the UE has connected to the node.

3. Checking the connection history of the handover target IAB host node: the connection history of the handover target IAB hosting node may be reviewed to determine whether there are UEs already connected to the node. These histories may be kept in log files of the edge IAB node or network device.

4. Checking the connection state of the UE: the connection status of the UE may be checked to determine whether the UE has connected to the edge IAB node. If the UE has connected to the edge IAB node, it is indicated that it has left the handover target IAB home node.

In the scheme, by inquiring whether the UE is connected to the handover target IAB host node before being connected to the edge IAB node, the operation of sending the configuration information to the UE can be directly performed under the connected condition, and the configuration information sending efficiency is improved to a certain extent. Meanwhile, the UE can preprocess the connection before the connection with the handover target IAB host node, so that the congestion problem caused by information synchronization is avoided during actual connection, and the handover speed of the IAB host node is improved.

On the basis of the above technical solutions, optionally, the first handover condition includes a condition that the UE has a tendency to move toward a network coverage of a handover target IAB host node topology according to location information and/or motion data information of the UE;

In the scheme, the position information and/or the motion data information of the UE can be queried at regular time, and when the distance between the position information of the UE and the handover target IAB host node is continuously reduced; or the motion direction in the motion data information is the direction close to the handover target IAB host node, and the motion speed is above a certain value, so that the condition that the UE has the network coverage moving trend towards the topology structure of the handover target IAB host node can be determined.

If the position information of the UE is in the network coverage of the switching target IAB host node topological structure; or the motion direction in the motion data information of the UE is the direction approaching to the handover target IAB host node, and the motion speed is above a certain value in the network coverage of the topology structure of the handover target IAB host node, and determining the condition that the UE has entered into the network coverage of the topology structure of the handover target IAB host node.

In the scheme, the specific mode of transmitting the configuration information to the UE can be determined according to different conditions by prescribing the specific rules of the first switching condition and the second switching condition, so that the configuration information transmission efficiency is improved to a certain extent.

S208, if so, identifying the location information and/or motion data information of the UE connected to the edge IAB node.

The location information of the UE may be coordinates of the UE on a world map, which may be expressed in the form of (latitude, longitude). For example, the UE is now in a position of 30 degrees north latitude and 120 degrees east longitude, which may be expressed in the form of (30 ° N,120 ° E).

The motion data information may include information such as a motion speed and a motion direction of the UE. The movement speed can be expressed in m/s, and the movement direction can be expressed in terms of a movement direction and a movement angle of the UE, for example, the movement direction of the UE is north-east, and the movement angle is 30 degrees, and the movement direction is north-east 30 degrees.

When the UE is in a starting-up state, a signal is automatically transmitted at fixed time to contact with the IAB host node, and the data can be forwarded to the IAB host node through the IAB intermediate node when the UE transmits the data to the connected IAB host node, so that a signal detector can be arranged in the IAB intermediate node, and the position information of the UE can be automatically identified after the signal of the UE is detected. Specifically, a positioning tracker of a Global Positioning System (GPS) in the UE (Navigation SatelliteTiming And Ranging Global Position System) can be used for acquiring the position information of the UE, and two positioning technologies of GPRS (General packet radio service general packet radio service) are used for realizing accurate knowing of the specific position of a positioning object in a short time through the GPS (Navigation SatelliteTiming And Ranging Global Position System GPS). Because the GPS positioning tracker acquires the position information through GPRS in the Internet of things card, the Internet of things card can transmit the real-time position information of the UE to the IAB intermediate node through the network, and the IAB intermediate node obtains the position information of the UE after data conversion. The GPS is a satellite-based positioning system for obtaining geographic position information and accurate universal coordination time. GPRS is a wireless packet-switched technology that provides end-to-end and wide area wireless IP (Protocol for interconnection between internet Protocol networks) connectivity.

The motion data information can identify the motion speed and the motion direction through the acceleration sensor and the direction sensor in the UE, and the IAB intermediate node can identify the motion data information by reading the data of the acceleration sensor and the direction sensor and processing the data through a certain algorithm.

S209, determining whether the UE has a first switching condition according to the position information and/or the motion data information of the UE.

When the distance between the position of the UE and the coverage area of the handover target IAB host node is within a certain range, the first handover condition may be considered to be satisfied, for example, when the coverage area of the handover target IAB host node is a circular area with a radius of 500m, it may be specified that when the position of the UE is more than 100m from the coverage area of the IAB host node currently connected, the first handover condition is considered to be satisfied when the distance between the position of the UE and the coverage area of the handover target IAB host node is within 100 m; when the motion direction of the UE is a direction from the currently connected IAB host node to the handover target IAB host node and the motion speed reaches a certain value, the UE may also be considered to satisfy the first handover condition, for example, the motion speed may be specified to reach 2m/s, and the motion direction is a direction from the currently connected IAB host node to the handover target IAB host node and then the UE may be considered to satisfy the first handover condition.

The first switching condition may be stored in advance in a memory chip of the current IAB host node, and after the position information and/or the motion data information of the UE are acquired, the current IAB host node automatically invokes the first switching condition in the memory chip and compares the first switching condition with the acquired position information and/or motion data information of the UE, and if one of the conditions is satisfied, that is, the position information of the UE satisfies the condition or the motion data information satisfies the condition, it is determined that the UE satisfies the first switching condition.

And S210, if the configuration information is provided, the configuration information is sent to the UE, so that the UE pre-stores the configuration information of the handover target IAB host node.

To send the configuration information of the handover target IAB home node to the UE, the UE may pre-store the configuration information of the handover target IAB home node, by:

1. information for handover of a target IAB host node is defined and configured in a control plane in the IAB network, including identification, address and other related information of the target IAB host node.

2. The configuration information is encoded into a format recognizable by the UE and transmitted to the UE. The configuration information may be sent to the UE in a variety of ways, such as a short message, a configuration file, and control signaling.

3. Configuration information of a handover target IAB host node is pre-stored on the UE. The UE may save the configuration information to local storage through a configuration interface or command line interface for use in switching to the target IAB host node.

4. Automatic handover is implemented on the UE. When the UE needs to switch to the target IAB hosting node, it may use the pre-stored configuration information to find and connect to the target IAB hosting node.

It should be noted that before the configuration information is sent to the UE, it needs to be ensured that the UE has completed steps such as identity authentication and authorization to ensure security and confidentiality. In addition, since changes in the network topology may affect the configuration information of the handover target IAB host node, the configuration information needs to be updated and reconfigured periodically.

In this embodiment, by identifying whether the edge IAB node is connected with the UE and pre-storing the configuration information of the target IAB host node when the UE is connected, the speed of switching the UE to the target IAB host node can be increased, and the problem that congestion is caused by information synchronization is required when the UE is switched to the target IAB host node is avoided.
