Fig. 1 is the flow chart according to the signal acceptance method of the embodiment of the invention.As shown in Figure 1, this method mainly comprises following processing:
The calibration-gain that step S102:BBU gets access to according to the antenna calibration handling process is determined the passage that need be set to enable;
Result notification RRU after step S104:BBU will determine is so that the channel receiving signal that RRU enables.
In the correlation technique, in the BBU side antenna calibration process, the passage of calibration failure has reduced the wave beam forming performance of antenna, causes the consistency variation of passage etc.In method shown in Figure 1, the calibration-gain that BBU gets access to according to the antenna calibration handling process determine the passage that needs are set to enable and will determine after result notification RRU, so that the channel receiving signal that RRU enables, and then improved the wave beam forming ability of antenna calibration, strengthened the consistency of passage.
Need to prove that after the base band calibration module is finished calibration, carry the calibrated channel information of calibration result, channel gain compensation difference, renewal, notice calibration management module antenna calibration finishes.After calibration management module receives that antenna calibration is responded, if up calibration compensates channel gain for difference and is configured to RRU, and with the calibrated channel information configuration upgraded to RRU.
Preferably, before execution in step S102, can also comprise that following processing: BBU receives the notification message that channel status changes or channel alarm changes that comes from RRU.
Need to prove, the present invention is on the basis in the periodic antenna calibration of antenna calibration, BBU that existing nms subsystem is initiated, three kinds of calibrations of antenna calibration triggering source that RRU initiates, the antenna calibration that has increased channel status variation or channel alarm change triggers in addition newly triggers the source, wherein, the channel status variation mainly comprises: whether current each passage is available; The channel alarm variation mainly comprises: passage standing-wave ratio alarm, the alarm of passage excess temperature etc.BBU receives the notification message that channel status changes or channel alarm changes of RRU to trigger the antenna calibration flow process.

Step S210: judge and whether adjust number of times less than default adjustment number of times (for example: 3 times);
Step S212: if less than, then RRU initiates the antenna calibration handling process again, forwards step S202 to, adjusts counter simultaneously and adds 1; Otherwise, continue execution in step S214;
