In the embodiment of the present application, the donor base station may adopt a structure in which CU and DU are separated, and the relay node may also adopt a structure in which CU and DU are separated, wherein the DU entity is located on the relay node, and the CU entity is located on the donor base station. In addition to the DU entity, the relay node also includes a mobile terminal (mobile termination, MT) entity. Specifically, the CU and DU in the donor base station 104 in FIG. 1 are connected through the F1 interface, and the CU and the NGC 105 are connected through the NG interface. And, the DU in the donor base station 104 is connected to the MT in the relay node 103 through the Uu interface, the DU in the relay node 103 is connected to the MT in the relay node 102 through the Uu interface, and the DU in the relay node 102 Connect with UE101 through Uu interface. That is to say, for the DU in the donor base station 104, the MT in the relay node 103 is regarded as a UE, and for the MT in the relay node 103, the DU in the donor base station 104 is regarded as a UE. becomes a base station. Similarly, for the DU in the relay node 103, the MT in the relay node 102 is regarded as a UE, and for the MT in the relay node 102, the DU in the relay node 103 is regarded as a UE. Think of it as a base station. Similarly, for the terminal device 101, the DU in the relay node 101 is regarded as a base station.

For the convenience of description, the following description will take the host base station 104 as the IAB host base station, the relay node 103 as the IAB node 2, the relay node 102 as the IAB node 1, and the terminal device 101 as the UE as examples, but this description does not constitute a Application Restrictions.

For the IAB system architecture shown in FIG. 1 , the IAB host base station needs to manage multiple IAB nodes below it. If the IAB host base station wants to manage the IAB node, it first needs to determine whether the IAB node can be connected to the IAB host base station. At present, the main method for the IAB host base station to determine whether an IAB node can access the IAB host base station is: the IAB host base station pre-configures the equipment serial number (equipment serial number, ESN) of the IAB node that can access the IAB host base station ), the IAB host base station receives the ESN reported by the IAB node, and judges whether the ESN reported by the IAB node is included in the pre-configured ESN. enter. It is explained here that each IAB node corresponds to a unique ESN.

Exemplarily, it is assumed that a certain IAB node needs to be managed by the IAB master base station. Then the method is: the installer first installs the IAB node, records the ESN of the IAB node and then notifies the background operator, and then powers up the IAB node so that the IAB node is in a working state; when the background operator receives the ESN, the ESN corresponding to the IAB node will be set in the IAB host base station, so that the ESN of the IAB node is stored in the IAB host base station. At this time, for the IAB node, if it wants to access the IAB host base station, it needs to send access request information to the IAB host base station and report its own ESN. Correspondingly, for the IAB host base station, after receiving the access request message and the sent ESN of the IAB node, it will check whether the IAB host base station includes the ESN sent by the IAB node, and if so, it proves that the IAB node can If not, it proves that the IAB node does not belong to the relay node that can be managed by itself.

It can be understood that when the IAB host base station uses ESN to determine whether the IAB node can be connected to the IAB host base station, if an IAB node has a problem, it may need to replace the IAB node, so since each device corresponds to a unique ESN, so when the IAB node is replaced, the ESN will change. At this point, if the IAB host base station wants to manage the replaced IAB node, it must first require a background operator to rewrite the ESN of the replaced IAB node into the IAB host base station. That is to say, the replaced IAB node must wait until the ESN is included in the IAB host base station before it can be connected to the IAB host base station, resulting in a cumbersome process and further slowing down the access speed of the replaced IAB node .

Secondly, when the IAB host base station determines the IAB node based on the ESN, because the ESN needs to be notified by the installer to the background operator first, and then the background operator writes the ESN information into the IAB host base station, there is a transmission error problem in the whole process , For example, there are problems such as missing copying, wrong copying, wrong delivery, and missing writing.

In view of this, an embodiment of the present application provides a management method for integrated access and backhaul nodes. In the method, the IAB host base station determines whether the IAB node can be managed based on the location information of the IAB node. It can be understood that when the IAB node is replaced, since the location information of the replaced IAB node is almost the same as the location information of the IAB node before the replacement, compared with the ESN, if the IAB master base station uses the location information to determine the replacement Whether the subsequent IAB node can be managed, there is no need to wait for background personnel to pre-configure the location information into the IAB host base station, thereby simplifying the management process of the IAB host base station, and further improving the access speed of the IAB node.

FIG. 2 is a schematic flowchart of a management method for integrated access and backhaul nodes provided by an embodiment of the present application. The flowchart shown in FIG. 2 describes the method from the perspective of interaction between the IAB node and the IAB host base station.

As shown in FIG. 2, the method provided by the embodiment of the present application includes S201, S202, and S203. Each step in the method shown in FIG. 2 will be described in detail below. Wherein, the sending of the access request information in S201 and S202 is performed by the IAB node, and the receiving of the access request information in S202 and S203 are performed by the IAB donor base station. Wherein, the IAB master base station in this embodiment stores N pieces of target location information, and the N pieces of target location information are used to indicate the location information of N IAB nodes.

S201. The IAB node determines location information.

In this embodiment, the IAB node can be regarded as a physical entity that needs to be managed by the IAB master base station.

In this embodiment, if the IAB node wants to communicate with the IAB host base station, the IAB node has to determine the location information to report its own location information to the IAB host base station.

In an implementable manner, the IAB node includes an MT component. Among them, the MT component can be regarded as a mobile terminal device, which can scan multiple surrounding base stations. Therefore, in this implementation manner, the location of the IAB node can be obtained through the mobile network assisted positioning technology.

Among them, the principle of the mobile network-assisted positioning technology is that the terminal device transmits signals to multiple base stations with known locations, and then multiple base stations send response signals to the terminal device. The response signal carries characteristic information related to the location of the base station. When the terminal device After receiving these signals, determine the geometric position relationship between it and each base station, and estimate its own position according to the relevant algorithm, so as to obtain its own position information. Exemplarily, as shown in FIG. 3 , assuming that the IAB node has scanned an IAB host base station and two base stations (base station 1 and base station 2 in FIG. 3 ), the IAB node can pass through the one IAB host base station and the two base stations. Get the location information of the current IAB node. For the specific implementation manner, reference may be made to the description in related technologies, which will not be repeated here.

In another practicable manner, the location information of its location can be pre-configured on the IAB node, so that when the IAB node needs to use the location information, it can read the location information from the configuration information.

S202. The IAB node sends access request information to the IAB host base station, where the access request information includes location information of the IAB node. Correspondingly, the IAB donor base station receives the access request information.

In this embodiment, the location information of the IAB node can be regarded as an identifier of the IAB node, and the IAB master base station can determine whether the IAB node can be managed through the location information.

It can be understood that if the IAB node wants to communicate with the IAB host base station, the IAB node must first access the IAB host base station. Similarly, if the IAB host base station wants to realize the management of the IAB node, it also needs to communicate with the IAB node establish connection.

In this embodiment, if the IAB node needs to access the IAB host base station, it first needs to send access request information to the IAB host base station, and since the IAB host base station also needs to determine whether the IAB node is a manageable object, it also needs to An identification information capable of determining whether the IAB node is a manageable object is required. In this embodiment, the access request information sent by the IAB node includes location information, and accordingly, the IAB donor base station can obtain the location information according to the received access request information.

It is noted here that the embodiment of the present application does not limit the form of the access request information sent by the IAB node to the IAB host base station. For example, the access request information may be radio resource control (radio resource control, RRC) signaling, and then the signaling carries the location information of the IAB node.

S203. When the distance between the location of the IAB node and any one of the N target locations is less than or equal to a preset threshold, the IAB master base station allows the IAB node to access.

In this embodiment, the IAB master base station stores N pieces of target location information, the N pieces of target location information are in one-to-one correspondence with the N locations, and each piece of target location information is used to indicate a location.

It can be understood that since the location information generally fluctuates within a range, that is, the location information of the IAB node at the current moment may be different from the previous moment, but for a location, the fluctuation generally does not exceed one Threshold, therefore, the embodiment of the present application sets a preset threshold, as long as the distance between the location and the target location is smaller than the preset threshold, it is considered that the two locations represent the same IAB node.

As an example, since the target location information of N IAB nodes is stored in the IAB donor base station, the IAB donor base station can manage the N IAB nodes. That is, if one of the N IAB nodes sends an access request to the IAB host base station and reports location information, the reported location will generally be different from the location of the IAB node pre-stored in the IAB host base station. The distance of the target location is within a preset threshold, so the IAB host base station will consider the IAB node as a device that can be managed, and then the IAB node can be allowed to access.

As yet another example, when the distance between the reported location and any one of the N target locations is greater than a preset threshold, the IAB parent base station does not allow the IAB node to access. That is to say, assuming that after an IAB node initiates an access request to the IAB donor base station and reports its own location information, since the IAB donor base station does not have a target location within a preset threshold with the location, the IAB donor base station If the IAB node is considered not to be a manageable object, the IAB node may not be allowed to access.

It can be understood that, in the prior art, that is, when the IAB host base station is managed through the ESN, if an IAB node has a problem, the IAB node needs to be replaced, and the ESN of the IAB node will change. At this point, if the IAB host base station wants to manage the replaced IAB node, it must first require background operators to rewrite the ESN of the replaced IAB node into the IAB host base station, which will lead to a cumbersome process. , resulting in slow IAB node access. In this solution, when the IAB host base station determines whether the IAB node can be accessed through the location information, even if a certain IAB node has a problem and needs to be replaced, since the location information does not change, there is no need to wait for the background personnel to write In other words, since the location information of the replaced IAB node is consistent with the location information of the IAB node before the replacement, and the location information of the IAB node before the replacement has been recorded in the IAB parent base station , so the replaced IAB node can reduce the waiting time for background personnel to write to the IAB host base station, and further, the access speed of the IAB node can be improved.

As an optional embodiment, after the IAB host base station determines whether to allow the IAB node to access based on the target location information reported by the IAB node, the IAB host base station can send the first information to the IAB node. Correspondingly, the IAB node receives the information sent by the IAB host base station. The first information is used to indicate whether the IAB host base station allows the IAB node to access.

As an example, if an IAB node sends an access request to the IAB owner base station and reports location information, if the IAB owner base station stores a target location within a preset threshold of the location information, the IAB owner The base station will consider the IAB node as a device that can be managed. At this time, the IAB host base station can send the first information to the IAB node, and the first information is used to indicate to the IAB node that it can access the IAB host base station.

As another example, after an IAB node initiates an access request to the IAB donor base station and reports its own location information, if there is no target location within a preset threshold with the location information in the IAB donor base station, the IAB The host base station will consider that the IAB node is not a manageable object. At this time, the IAB host base station sends first information to the IAB node, and the first information is used to indicate to the IAB node that it cannot access the IAB host base station.

As an optional embodiment, if an IAB host base station wants to manage the above N IAB nodes, the premise is that the IAB host base station receives N target location information input by the administrator.

In an achievable manner, the site survey personnel can first determine the installation locations of the N IAB nodes through on-site site survey, such as the latitude and longitude of the IAB nodes, and then notify the background operator of the location information of the site survey, and the background operation After receiving the location information, the personnel can write the location information into the IAB host base station, so that the IAB nodes corresponding to the N target location information become the management objects of the IAB host base station.

Optionally, the location information of the IAB node includes latitude and longitude information.
