Step S104, the network management system receives a response message sent by the second network element, where the response message carries a second control instruction of the second network element.
Here, the second control instruction is used to manage the second network unit and/or a network device externally connected to the second network unit.
Step S105, the network management system determines the device management system of the first network element and the device management system of the second network element according to the identifier of the first network element and the identifier of the second network element.
Step S106, the network management system sends the first control instruction and the second control instruction to the device management system of the first network element and the device management system of the second network element, respectively.

The embodiment of the present application further provides a method for managing another network element, where the method includes:
in step S201, the network management system obtains the identifier of the first network element and the first control instruction.
Here, the first control instruction is used to manage the first network element and/or a network device externally connected to the first network element.
Step S202, the network management system obtains the identifier of the second network unit corresponding to the first network unit and a second control instruction according to the identifier of the first network unit.

Step S204, if the identifier of the first network element and the identifier of the second network element satisfy a preset condition, the network management system establishes a connection between the first network element and the second network element.
Here, the first network unit is connected to at least one of the second network units, and each of the second network units is connected to one of the first network units, and taking the first network unit as CU and the second network unit as DU as an example, in the NMS, the logical management relationships between CU and DU are as follows: one CU is connected to at least one DU, and one DU is connected to one CU. When a CU and a DU are connected, the DU reports identity information to the CU and requests the establishment of the connection between the CU and the DU, where the request for establishing the connection may also be initiated by the CU, and the identity information may be carried in a request message and reported to the NMS, and the NMS may process the received request message, for example, forward the request message to the corresponding CU or DU, where the CU and the DU may establish the connection according to a handshake protocol or other manners.
The preset condition is that the identifier of the first network element and the identifier of the second network element meet a preset condition, for example, if the identifier of the first network element and the identifier of the second network element are the IP of the first network element and the IP of the second network element respectively, it is determined whether the IP of the first network element and the IP of the second network element can represent that the first network element and the second network element belong to a local area network, and if the identifiers are in a local area network, the network management system establishes a connection between the first network element and the second network element.
In other embodiments, the method further comprises: if the first network unit and the second network unit are successfully connected, the network management system receives first state information sent by the first network unit and/or the second network unit, wherein the first state information is state information used for representing successful connection; if the first network unit and the second network unit fail to connect, the network management system receives second state information sent by the first network unit and/or the second network unit, wherein the second state information is state information used for representing connection failure; and the network management system sends corresponding instructions to the first network unit and/or the second network unit according to the first state information and the second state information.
Here, taking the first network unit as CU and the second network unit as DU as an example, CU has DU identity and function identification and decision function and corresponding security control function, and when information in a connection request reported by DU does not meet the expected requirement of CU, CU needs to immediately report key information such as information reported by DU and information of decision process to NMS. The DU has the functions of CU identity and function identification and judgment and corresponding safety control, and when the information in the connection response provided by the CU does not meet the expected requirement of the DU, the DU needs to immediately report the key information such as the information reported by the CU and the information in the judgment process to the NMS. The CU and DU should be subject to the management of the NMS, and the instructions sent by the NMS are executed. The instruction of the NMS is the final decision when there is a mismatch or other problem between the CU and DU, and the instruction of the NMS may be any instruction that can terminate the connection or re-enter the next round of establishing the connection (final decision) when there is a mismatch or other problem.
Step S205, sending the first control instruction and the second control instruction to the device management system of the first network element and the device management system of the second network element, respectively.
In other embodiments, the method further comprises: if the first network unit and/or the second network unit has the function of managing the RRU, establishing connection between the first network unit and/or the second network unit and the RRU; sending the identifier of the first network element and/or the identifier of the second network element to the RRU; wherein the first network unit and/or the second network unit are configured to manage the RRU.
In the embodiment of the application, by setting the identity and function identification and judgment function and the corresponding safety control function for the first network unit and the second network unit, when the connection is failed to be established or the communication fails, the problem can be reported and solved in time.
The embodiment of the present application further provides a method for managing another network element, where the method includes:
in step S301, the gNB is divided into two device objects, namely CU and DU, which can be used for independent management.
In step S302, identities for management are allocated to the CUs and DUs in the NMS, respectively.
Here, the identity may be an IP address, or a unique identity authentication identity, or other forms of identities are assigned, where the identity is pre-configured to uniquely identify the CU and the DU.
In step S303, the NMS manages the CUs and the DUs respectively through the management identity.
In the embodiment of the present application, in the NMS, the logical management relationship between the CU and the DU is: one CU is connected to at least one DU, and one DU is connected to one CU. When a CU and a DU are connected, the DU reports identity information to the CU and requests the establishment of the connection between the CU and the DU, where the request for establishing the connection may also be initiated by the CU, and the identity information may be carried in a request message and reported to the NMS, and the NMS may process the received request message, for example, forward the request message to the corresponding CU or DU, where the CU and the DU may establish the connection according to a handshake protocol or other manners.
Here, if the CU and the DU satisfy the preset condition, the CU cannot reject when the NMS specifies that the CU should establish a connection with one or more DUs, and similarly, the DU cannot reject the CU specified by the NMS as a connection object, but if the authentication is not correct or there is another problem, the security control function may be started, and the decision process is reported and rejected.
In other embodiments, the CU has a DU identity and function identification and decision function and a corresponding security control function, and when information in a connection request reported by the DU does not meet the expected requirement of the CU, the CU needs to immediately report key information, such as information reported by the DU and information of a decision process, to the NMS. The DU has the functions of CU identity and function identification and judgment and corresponding safety control, and when the information in the connection response provided by the CU does not meet the expected requirement of the DU, the DU needs to immediately report the key information such as the information reported by the CU and the information in the judgment process to the NMS. The CU and DU should be subject to the management of the NMS, and the instructions sent by the NMS are executed. The instruction of the NMS is the final decision when there is a mismatch or other problem between the CU and DU, and the instruction of the NMS may be any instruction that can terminate the connection or re-enter the next round of establishing the connection (final decision) when there is a mismatch or other problem.
In the embodiment of the present application, the CU and the DU must report their respective states according to the mode (reporting period, form, etc.) and content specified by the NMS, and if the connection is successfully established, the state of successfully establishing the connection may be reported, and if the connection is failed to be established, the state of failing to establish the connection may be reported, and the reason for the connection failure of the NMS is notified.
Step S304, the CU is used as a logic function entity and can be used for managing the RRU; or, the DU is used as a logic function entity and can be used for managing the RRU, when the CU and the DU have the function of managing the RRU at the same time, the CU or the DU is selected according to the instruction of the NMS, and the RRU is managed according to the CU or the DU selected by the NMS.
Here, the NMS generates two sets of management objects with the CU and the DU respectively when generating the management objects, which is implemented by an application, for example, generating entity objects based on the CU in the application, and if necessary, generating the RRU in the CU; or, if necessary, generating an RRU in the DU, and establishing a logical relationship between the RRU and the CU or the DU, where the RRU may also be set separately as long as the management of the RRU by the CU and the DU can be implemented. After generating a CU logical function, the NMS assigns an identity for management to the CU logical function. After generating a DU logical function, the NMS assigns an identity for management to the DU logical function.
And S305, the EMS realizes interconnection between the CUs and the DUs and corresponding external equipment according to the identity of each CU and the identity of each DU.
Fig. 3 is a block diagram of management models of a CU and a DU in an NMS according to an embodiment of the present application, as shown in fig. 3, a network management system 301 may manage a central unit 302 and a distribution unit 303 in a gNB, and send an identifier and a control instruction of the central unit 302 and an identifier and a control instruction of the distribution unit 303 to a first network device management unit 304 and a second network device management unit 305 through corresponding interfaces, respectively, and the first network device management unit 304 and the second network device management unit 305 connect the central unit 302 and the distribution unit 303 to a first external device 306 and a second external device 307 according to the identifier and the control instruction of the central unit 302 and the identifier and the control instruction of the distribution unit 303, respectively.
In this embodiment, the device management system of the central unit and the device management system of the distribution unit may respectively manage the central unit and the distribution unit. The network management system can establish connection with the network equipment management system through a preset interface, so that the connection between the network management system and the network equipment management system is realized, and the centralized unit and the distributed unit are separately managed according to corresponding identifications.
