Embodiment
Basic thought of the present invention is: among the present invention, eRRU mainly comprises the eRRU radio frequency processing board, and eBBU mainly comprises eBBU master control borad and eBBU physical boards.After the eRRU radio frequency processing board starts, take the mode of CPRI (Common Public RadioInterface) interface control word at first to get through physical channel between eRRU radio frequency processing board and the eBBU physical boards between eRRU radio frequency processing board and the eBBU physical boards; Then, the eRRU radio frequency processing board is initiatively initiated network configuration packet request to the eBBU master control borad, obtains pid information, and eRRU sets up UDP with eBBU and links.
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
The flow process of the method for eRRU startup self-configuring of the present invention may further comprise the steps as shown in Figure 2:
Set up the physical channel between steps A, eRRU radio frequency processing board and the eBBU physical boards.Steps A specifically comprises:
Step 201, eBBU master control borad normally start.
Step 202, eBBU physical boards power on and finish.
Behind step 203, the eRRU radio frequency processing board electrifying startup, initiatively initiate the physical channel and set up request to the eBBU physical boards.CPRI interface control word mode is adopted in this request.
Step 204, eBBU physical boards generate the group network topological structure information of eRRU according to the physical channel that the receives request of setting up; Information such as (MAC, Media Access Control) address are controlled in the cascade system, IP address, the media interviews that comprise eRRU in this group network topological structure information.
Step 205, eBBU physical boards are responded the physical channel of eRRU radio frequency processing board and are set up request, and the group network topological structure information of eRRU is sent to the eRRU radio frequency processing board; The eRRU radio frequency processing board is received the group network topological structure information of eRRU, shows that the physical channel between eRRU radio frequency processing board and the eBBU physical boards is set up.
Step B, eRRU and eBBU master control borad are set up the UDP link.Step B specifically comprises:
Step 206, eRRU radio frequency processing board are initiatively initiated the request of networking configuration packet by the UDP message to the eBBU master control borad;
Step 207, eBBU master control borad are responded the network configuration packet request of eRRU radio frequency processing board by the UDP passage; The information such as frame, frame, groove number that comprise RRU during eBBU master control borad configuration packet is responded.
Step 208, eRRU radio frequency processing board are initiated the pid information request to the eBBU master control borad;
The eRRU radio frequency processing board is extracted the frame, frame, groove number of RRU from the configuration packet that the eBBU master control borad is responded, generate the pid information request package, carries in the UDP message, to eBBU master control borad request pid information.
After step 209, eRRU radio frequency processing board were obtained pid information, eRRU and eBBU set up the UDP link, started flow process to carry out follow-up software version download etc.
In addition, in the said method, in the step 203, behind the eRRU radio frequency processing board electrifying startup, initiatively when the eBBU physical boards is initiated physical channel foundation request, if in time do not obtain responding, a request number of times thresholding can be set or a RQ cycle is set, for example: after the eRRU radio frequency processing board active request ten times, the eBBU physical boards is not still responded, at this moment, the eRRU radio frequency processing board restarts, and sends request to the eBBU physical boards again.And in step 204, after the eBBU physical boards generated the group network topological structure information of eRRU, the eBBU physical boards can also report the group network topological structure information of eRRU to the eBBU master control borad; The eBBU master control borad writes database with the group network topological structure information of eRRU, uses in order to subsequent query.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
