In a complex networking environment, the demand of optical fibers and optical modules is large, and the connection is also complex. By using the networking mode in the embodiment, the cost can be saved, the complexity of the connection can be reduced, and the error condition can be reduced. It should be noted that, in actual use, the number of cascades of each device may be determined according to actual situations, and is not limited to the networking mode in this embodiment.

On the basis of the foregoing embodiment, before the 5G base station in the multimode base station receives the control message of the 5G base station and the 4G base station in the multimode base station to the RRU, the method further includes: receiving a first starting notification sent by the 4G base station, and if a response result of the first starting notification is returned to the 4G base station within a first preset time length, setting the 5G base station to be in a main management and control mode; wherein the 5G base station and the 4G base station are in a same frame;
the common frame of the 5G base station and the 4G base station in the multimode base station means that a baseband single board and a main control board of the multimode base station are in the same frame.
And the 4G base station and the 5G base station mutually send starting notifications when starting, and select the main cooperation mode for management according to the returned response result. And if the 5G side successfully returns the response result of the starting notification within the first preset time, setting the 5G side as a main control mode.
And sending a second starting notification to the 4G base station, and if a response result of the second starting notification returned by the 4G base station is received within a second preset time length and a response result of the first starting notification is not returned to the 4G base station within the first preset time length, setting the 4G base station to be in a cooperative management and control mode.

In addition, the presence states of the 4G side and the 5G side are detected by the heartbeat messages of the 4G side and the 5G side, and the master mode is switched according to the presence states.
On the basis of the foregoing embodiments, in this embodiment, the control message is an access flow establishment message, and the response message is parameter information of the RRU;
the management of the multi-mode base station to the RRU comprises access management. The access flow between the RRU and the multimode base station is to send to the 5G baseband through an IR (Infrared) interface of the multimode base station, and interact only with the 5G base station. And after the RRU is accessed, the 5G directly forwards the parameter information of the RRU to the 4G side.
The IR interface refers to an interface between the BBU and the RRU, and is connected by an optical fiber.
The method comprises the following steps that a 5G base band of a 5G base station in a multimode base station receives a control message for the RRU sent by the 5G base station in the multimode base station, and the step of forwarding the control message to the RRU comprises the following steps: after receiving an access request message broadcast by the RRU, sending an access flow establishment message to the RRU;
the process of accessing the multi-mode base station by the RRU is shown in fig. 3. The 4G base station and the 5G base station are in interprocess communication, and whether the communication is online or not is detected by sending heartbeat messages mutually. The 5G and the RRU communicate with each other through a TCP (Transmission Control Protocol), and send a heartbeat message to detect whether a line is dropped. And under the condition that the 4G, the 5G and the RRU are all detected to be on line, the RRU initiates a broadcast packet to the 5G base station.
The receiving a response message of the control information sent by the RRU and sending the response message to the 4G base station and/or the 5G base station includes: receiving parameter information of the RRU reported by the RRU according to the flow establishing message; sending the parameter information of the RRU to the 5G base station, so that the 5G base station can access the RRU to the 5G base station according to the parameter information of the RRU; and forwarding the parameter information of the RRU to a 4G base station, so that the 4G base station can access the RRU to the 4G base station according to the parameter information of the RRU.
And the RRU initiates a broadcast packet to the 5G base station, and the 5G base station initiates the establishment of an access flow after receiving the broadcast packet and sends a broadcast packet response message. After receiving the broadcast packet response message of the 5G base station, the RRU establishes a TCP link and starts to initiate an access flow message. And finishing the access process after the RRU information is reported. The 5G master control forwards the parameter information of the RRU to a 5G baseband through resource synchronization, and the 5G baseband forwards the message to a 4G side through an IR interface; thereby realizing the access of RRU at 4G and 5G sides. The method comprises the following specific steps:
and 301, establishing a heartbeat task at the 4G side and the 5G side, and performing mutual sending and detection of heartbeat messages of the 4G side and the 5G side. The heartbeat message is normally received and sent, and the problem of overtime does not exist, which indicates that the current connection is normal and the message can be normally sent;
step 302, after the RRU detects synchronization between the RRU and 5G. Sending heartbeat messages to each other through a heartbeat detection task, detecting whether the connection between the RRU and the 5G is normal, if detecting that the heartbeat messages are lost, disconnecting a task link, and closing TCP connection; and if the heartbeat message is detected to be normal, the communication with the 5G is normal. And the RRU only performs heartbeat detection with the 5G base station.
Step 303, after the RRU detects synchronization between the RRU and the 5G. And the RRU initiates a starting message, encapsulates the acquired link ID, the optical port number information of the 5G base station, the MAC address and the like, and initiates a broadcast access request message to the BBU. The broadcast access request message is directly transmitted through the IR interface without special processing. The 5G baseband receives a broadcast access request message for driving a broadcast channel to report to the IR interface, and the format of the modified message is OSP (Outside Plant) message. And then, according to the link ID, the optical interface number information and the like, determining a target SFU (Store and Forward Unit), forwarding the message to a corresponding module, analyzing the RRU parameter information in the module, and determining whether the parameter information reported by the RRU is matched with the parameter information distributed by the base station. If the information matches, sending a broadcast access request response message to step 304; and if not, reporting an alarm, and the RRU continuously sends a broadcast access request.
Step 304, after receiving the BBU message, the RRU determines whether the current RRU has completed the broadcast access, if not, checks the link ID and the optical port number, determines whether the current RRU is the broadcast access response message of the RRU of the current stage, and if the current RRU is the RRU of the current stage, forwards the current RRU to the RRU access module. And the RRU analyzes the broadcast response message, judges whether a TCP link is established or not, and initiates the TCP link establishment if the TCP link is not established. Reporting an RRU information initiating channel establishment message to enter step 305; if so, directly returning.
305, the RRU initiates a channel establishment message, reports information such as RRU information bearing capacity and the like, and the IR interface performs large-small end conversion and then sends the information; and the 5G baseband processes the received message and forwards the message to the 5G master control. And the 5G side processes according to the current RRU state and sends a channel establishment response message.
Step 306, after receiving the message, the RRU confirms that the current TCP connection is established, modifies the IR interface protocol number in the IE (Internet Explorer, web browser) header to the message number used inside the RRU, and determines the target SFU according to the message number, and forwards the message to the corresponding module. And after receiving the channel establishment response message, configuring the RRU parameters, and then entering step 307.
Step 307, the RRU initiates an access completion acknowledgement message to 5G. After receiving the message, the 5G side calibrates the parameters, confirms that all the steps of the current RRU access are completed, and then modifies the state to be that the RRU access is completed, and then enters step 308.
Step 308, the 5G side confirms that the RRU access is completed, performs resource synchronization with the 4G side, forwards the parameter information of the RRU to the 4G side through a resource synchronization response message, and enters 309.
Step 309, the 5G baseband processes the synchronization message and forwards the message to the 4G through the bottom OSP messaging interface.
In step 310, the 4G receives the RRU parameter information, processes the RRU parameter information, synchronizes the RRU parameter information, confirms that the RRU access is completed, and performs step 311.
Step 311, the BBU side queries the RRU, and the step 312 is entered, and the access is completed.
In the embodiment, for the access process of the RRU, only the interaction of the access flow with the 5G base station needs to be performed, and after the RRU and the 5G access are completed, the 5G side directly forwards the RRU information, so that the RRU can be prevented from interacting with multiple systems in the access process, the RRU access process is simplified, and the problem of access risk is reduced.
On the basis of the above embodiments, in this embodiment, the control message is a parameter query message;
the management of the multi-mode base station to the RRU comprises parameter query. And the multimode base station sends the parameter query message to the RRU through the IR interface, and queries the parameter information of the RRU.
Receiving, by a 5G baseband of a 5G base station in a multimode base station, a control message for an RRU sent by a 4G base station and the 5G base station in the multimode base station, and forwarding the control message to the RRU, where the control message includes: receiving a parameter query message of the RRU sent by the 4G base station and sent by the 4G base station; receiving a parameter query message of the 5G base station to the RRU, wherein the parameter query message is sent by the 5G base station;
and the multi-mode base station queries the RRU parameters, including the parameter query of the 4G base station to the RRU and the parameter query of the 5G base station to the RRU. The 4G base station sends the parameter query message for the RRU to the 5G baseband through the inter-board message between the 4G base station and the 5G base station, and the 5G baseband forwards the parameter query message to the IR interface driver through the query message interface. The 5G base station directly forwards the parameter query message for the RRU to a 5G baseband through the inter-board message, and the 5G baseband is forwarded to the IR interface driver through the query interface.
And forwarding the parameter query message of the RRU by the 4G base station and the 5G base station to the RRU through an IR interface of the multimode base station so that the RRU can query the parameter information of the RRU according to the parameter query message.
The management of the multi-mode base station to the RRU is managed through the communication between the 5G base station and the RRU. The parameter query and setting of the RRU by the 4G base station are firstly sent to the 5G side, and the 5G side forwards the message to the RRU through a standard IR interface protocol. And the RRU response message is sent to the 5G side, and the 5G side forwards the message to the 4G side or the 5G side according to the slot number information. The RRU only needs to establish channel connection with the 5G base station, and the access process of the RRU only needs to communicate with the 5G base station. For the RRU, the internal access flow can be simplified; the problems of message blocking, message loss, overtime processing, forwarding errors and the like are avoided.
The process of the multimode base station querying the RRU parameter information is shown in fig. 4. The multi-mode base station is mainly used for updating and debugging the RRU parameters. The multi-mode base station sends and processes the RRU parameter query through a self-defined query parameter interface. And the 5G base band sends the parameter query message to the RRU through a bottom layer IR protocol through a query parameter interface. And after receiving the message, the RRU analyzes the message through the query parameter interface and returns a response message. The method comprises the following specific steps:
step 401, the 5G master sends RRU parameter information to be queried to the 5G baseband through a custom query parameter interface; after receiving the message, the 5G baseband needs to acquire message information, a procedure number, a link ID, and an optical port number. And recording the message of the set message information as BBU to RRU. And judging that the message comes from the 5G master control according to the slot number, and acquiring the link ID, the optical port number and the RRU type through the RRU number. According to the IR message structure definition, parameters such as link ID, optical port number, slot number, RRU type and the like are encapsulated into an IR message header, whether the message sent to the RRU is a main sending message is confirmed through the link ID, if so, an overtime timer is deleted, and a processing function is used for processing. And finally, sending the information to a bottom layer through an IR interface and forwarding the information to the RRU. Step 402 is entered.
