Embodiment
Below in conjunction with accompanying drawing, and technical scheme of the present invention is described further by embodiment.
At first port and the scanning message format to BBU and RRU is defined as follows:
Port name: with the BBU port BBU_PORT0 that is scanned is example, it connects the port 0 of first RRU, the port that the port one of first RRU connects 0, three RRU of port of next stage RRU is designated RRU0_PORT0, RRU0_PORT1, RRU1_PORT0, RRU1_PORT1, RRU2_PORT0, RRU2_PORT1 respectively.As the more RRU of cascade, the rest may be inferred for the port naming method.
The device scan message format: the scanning message mainly is made of a facility information structural array, and the size of array can be connected the number decision of RRU equipment by the BBU port.If a BBU port can connect 4 RRU, this array can be deposited 6 facility information structures so, and wherein two are the reservation of BBU port.The facility information structure is made up of the residing location index of equipment in device identification, the scanning process, can also comprise the miscellaneous equipment information that BBU is concerned about.Also have a scanning indication information in the scanning message, identifying this message is forward scan message, reverse scanning message or feedback message.Three kinds of message formats are identical.
Fig. 4 is for scanning the flow chart of identification in this embodiment to remote RF unit equipment information and networking mode.As shown in Figure 4, remote RF unit equipment information and networking mode being scanned identification may further comprise the steps:
Separately three kinds of different networking modes are described in detail again below.
As shown in Figure 5, the scanning process of chain networking mode comprises forward scan and reverse scanning, specifically describes as follows:
BBU select one not scanning port BBU_PORT0 as the scanning both port of origination, and with this port label for scanning, it sends a scanning message from the BBU_PORT0 port, the scanning of message is designated as the forward scan message, the device identification of first facility information structure is the BBU_PORT0 port-mark in the message, the device location index is 0, and the message remaining structure is not filled.
The RRU0_PORT0 port of first order RRU is received this message, therefrom takes out the device location index of upper level port, and device location index at the corresponding levels adds 1 on the upper level location index, and and information such as device identification deposit the next blank position of message together in; Then this message is mail to the RRU0_PORT1 port of RRU at the corresponding levels.The RRU1_PORT0 port of second level RRU receives that the device scan message handles in the same way, and message is sent to next stage.
Third level RRU receives the scanning message, handles the RRU2_PORT1 port transmission of back by it, does not detect back-signalling, illustrates that RRU at the corresponding levels is an afterbody.So changing scanning, it is designated as the feedback message, by the reverse loopback message of its RRU2_PORT0 port, second level RRU does not handle message after receiving reverse feedback message, continues to be sent to this message to upper level RRU, is sent to the BBU_PORT0 port of BBU always.
Third level RRU produces a new reverse scanning message immediately behind loopback feedback scan message, facility information at the corresponding levels is filled in first facility information structure, and location index is 0, sends the reverse scanning message to upper level RRU.
After second level RRU receives the reverse scanning message, handle, and continue to send the reverse scanning message, until the BBU_PORT0 port of BBU to first order RRU by the mode the same with the forward scan message.
Under the described chain networking mode of this process, the BBU_PORT0 port of BBU can be received feedback scan message and reverse scanning message continuously, fill information such as the BBU_PORT0 port-mark of BBU and location index in the next message structure position of reverse scanning message after, feedback scan message and reverse scanning message are compared checking, check whether resulting facility information is consistent with RRU cascade information.If unanimity then preserve scanning information, the BBU_PORT0 TCP process of BBU is finished.
In the same way another port of BBU BBU_PORT1 is scanned, will scan message and send to the BBU_PORT1 port, do not detect back-signalling, illustrate that the port does not connect RRU equipment, at this moment BBU_PORT1 is labeled as and scans the end of scan.
Behind the end of scan, BBU just can obtain the facility information of all RRU, because the RRU number of devices that the BBU_PORT0 port connects can the decision set net mode be the chain networking mode then more than one.
As shown in Figure 6, star-like networking mode can be regarded as a special case of chain networking mode, and the device scan message format under scanning message format and the chain networking mode is identical.To the scanning of BBU single port connection device also with the chain networking mode under the scanning of BBU single port identical.BBU finds that each port that connects RRU equipment has all only connected a RRU equipment after having scanned all of the port, can the decision set net mode be star-like networking mode then.
As shown in Figure 7, the scanning message format of ring-shaped network mode is identical with chain scanning message format.TCP process under the ring-shaped network mode is similar with the scanning process of chain networking mode.Initiate forward device scanning by the BBU_PORT0 port, RRU was to the processing of message during middle RRU equipment scanned with the chain networking mode the processing of device scan message.Different is, the BBU_PORT1 port of BBU has been received this forward scan message, then the port-mark of BBU_PORT1 and location index is filled into the next blank structure of message, and the forward scan process finishes.Because the port of initiating equipment scanning is different with the port that receives the scanning message at last, can the decision set net mode be the ring-shaped network mode then.The BBU_PORT1 port is initiated the reverse scanning process then, and final BBU_PORT0 port is received this reverse scanning message, then the port-mark of BBU_PORT0 and location index is filled into the next blank structure of message.Forward scan message that the end of scan of BBU_PORT0 port and BBU_PORT1 port, BBU are relatively received and reverse scanning message carry out the consistency of authorization information.Checking is passed through, and then preserves scanning information.Initiate other not scanning process of scanning port in the same way.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
