Here, taking the first network unit as a CU and the second network unit as a DU as an example, the CU has the DU identity and function identification and judgment function and the corresponding security control function. When the information in the connection request reported by the DU does not meet the expectations of the CU When required, the CU needs to immediately report key information such as the information reported by the DU and the information of the decision process to the NMS. The DU has the CU identity and function identification and judgment function and the corresponding security control function. When the information in the connection response provided by the CU does not meet the expected requirements of the DU, the DU needs to immediately report the information reported by the CU and the information of the judgment process and other key information. Report to NMS. Among them, the CU and DU should be subject to the management of the NMS, and the instructions sent by the NMS must be executed. When there is a mismatch between the CU and DU or other problems, the NMS command is the final decision. The NMS command can be any command. When there is a mismatch or other problems, the connection can be terminated or re-enter the next round of connection establishment ( final decision).

In other embodiments, the method further includes: if the first network element and/or the second network element has a function of managing an RRU, establishing the first network element and/or the second network connection between the unit and the RRU; sending the identity of the first network unit and/or the identity of the second network unit to the RRU; wherein the first network unit and/or the The two network elements are used to manage the RRU.

In this embodiment of the present application, by setting the identity and function identification and judgment functions and the corresponding security control functions for the first network unit and the second network unit, the establishment of a connection between the first network unit and/or the second network unit fails or When the communication fails, the problem can be reported and solved in time.

The embodiment of the present application also provides a management method for another network unit, and the method includes:

In step S301, the gNB is divided into two device objects that can be used for independent management, namely CU and DU.

Step S302: In the NMS, the CU and the DU are respectively allocated an identity identifier for management.

Here, the identity identifier may be an IP address, or a unique identity authentication identifier, or an identity identifier in other forms assigned, wherein the identity identifier is preconfigured and used to uniquely identify the CU and the DU.

Step S303, the NMS separately manages the CU and the DU through the management identity.

In this embodiment of the present application, in the NMS, the logical management relationship between a CU and a DU is: one CU is connected to at least one DU, and one DU is connected to one CU. When the CU is connected to the DU, the DU reports the identity information to the CU and requests the establishment of the connection between the CU and the DU. Here, the request to establish the connection can also be initiated by the CU, and the identity information can be carried in the request message and reported to the NMS , the NMS can process the received request message, for example, forward it to the corresponding CU or DU, wherein the CU and the DU can establish a connection according to a handshake protocol or other methods.

Here, if the CU and DU meet the preset conditions, when the NMS specifies that the CU should establish a connection with one or more DUs, the CU cannot refuse it. Similarly, the DU cannot refuse the CU specified by the NMS as the object of its connection, but if the authentication is incorrect Or when there are other problems, the security control function can be activated, and the judgment process can be reported and rejected.

In other embodiments, the CU has DU identity and function identification and judgment functions and corresponding security control functions. When the information in the connection request reported by the DU does not meet the expected requirements of the CU, the CU needs to report the information and judgment of the DU. Key information such as process information is immediately reported to the NMS. The DU has the CU identity and function identification and judgment function and the corresponding security control function. When the information in the connection response provided by the CU does not meet the expected requirements of the DU, the DU needs to immediately report the information reported by the CU and the information of the judgment process and other key information. Report to NMS. Among them, the CU and DU should be subject to the management of the NMS, and the instructions sent by the NMS must be executed. When there is a mismatch between the CU and DU or other problems, the NMS command is the final decision. The NMS command can be any command. When there is a mismatch or other problems, the connection can be terminated or re-enter the next round of connection establishment ( final decision).

In the embodiment of this application, the CU and DU must report their respective states according to the method (period of reporting, form, etc.) and content specified by the NMS. If the connection is successfully established, the status of the successful connection can be reported. Reports the status of connection establishment failure and informs the NMS of the reason for the connection failure.

Step S304, the CU, as a logical functional entity, can be used to manage the RRU; or, the DU, as a logical functional entity, can be used to manage the RRU. Indicates the selection of a CU or DU, and manages the RRU according to the CU or DU selected by the NMS.

Here, when the NMS generates management objects, two sets of management objects are generated by CU and DU respectively, which are implemented by the application program, for example, the CU-based entity object is generated in the application program, and if necessary, the RRU is generated in the CU; or , if necessary, generate an RRU in the DU, and establish a logical relationship between the RRU and the CU or DU, wherein the RRU can also be set independently, as long as the CU and the DU can manage the RRU. After generating a CU logical function entity, the NMS allocates an identity for management to the CU logical function entity. After generating a DU logical function entity, the NMS allocates an identity for management to the DU logical function entity.

Step S305, the EMS implements interconnection between the CU and the DU and the corresponding external device according to the identity of each CU and the identity of the DU.
