If follow-uply set up pseudo-carrier wave by master unit oneself, this step can be omitted.
Step 403: the carrier channel situation of each equipment in the detection system, set up pseudo-carrier wave according to different situations;
If set up pseudo-carrier wave by master unit oneself, can not detect the carrier channel situation of each equipment, promptly this step can be omitted.If step is that base station control device is initiated before, after then the base station receives and sets up pseudo-carrier wave instruction, sets up pseudo-carrier wave, and be handed down to master unit;
In this step, self check can at first be carried out in base station (comprising BBU and RRU), judges whether that unnecessary carrier channel sets up pseudo-carrier wave, and is if having, then ready to RNC or BSC feedback; Base station equipment notice master unit confirms whether master unit has unnecessary carrier channel to set up pseudo-carrier wave, and master unit is if be judged as unnecessary carrier channel, and is then ready to the base station equipment feedback; Master unit notice expanding element confirms whether expanding element has unnecessary carrier channel to set up pseudo-carrier wave, and expanding element is if be judged as unnecessary carrier channel, and is then ready to the master unit feedback; Expanding element notice far-end unit confirms whether far-end unit has unnecessary carrier channel to set up pseudo-carrier wave, and far-end unit is if be judged as unnecessary carrier channel, and is then ready to the expanding element feedback.After above-mentioned four equipment (if there is not expanding element, then being three equipment) are all ready, can set up pseudo-carrier wave, wherein any one is false, and all returns and can not set up pseudo-carrier wave.Through above-mentioned processing, make and to utilize carrier channel to set up pseudo-carrier wave between base station (BBU/RRU), master unit, expanding element, the far-end unit, and connect setting terminal and form Radio Link by far-end unit.
Step 404: the taking turn routing table that the master unit basis is set up in advance is to being issued pseudo-carrier wave by the far-end unit of taking turn, so that by the far-end unit of taking turn pseudo-carrier wave is handed down to wireless terminal;
After master unit is set up the taking turn routing table, can select each far-end unit in the taking turn routing table successively, issue pseudo-carrier wave to this far-end unit, so that this far-end unit is handed down to wireless terminal with pseudo-carrier wave as by the far-end unit of taking turn.
Step 405: master unit obtain by taking turn the first network measure information of far-end unit.
Wherein, referring to Fig. 5, pseudo-carrier wave is set up the process of signal flow and is in the embodiment of the invention: initiate one by base station control device and set up pseudo-carrier wave instruction, this pseudo-carrier wave does not carry service signal.After the base station receives instruction; Set up pseudo-carrier wave; Be handed down to master unit, be handed down to expanding element, be handed down to far-end unit by expanding element by master unit; Be transferred to wireless terminal (MS) by far-end unit again, the signal flow of wireless terminal feedback then oppositely is transferred to the base station through far-end unit, expanding element, master unit.
After base station control device initiates to set up pseudo-carrier wave instruction; Signal to noise ratio (the SNR of the level of the pseudo-carrier wave of monitoring wireless terminal feedback, wireless terminal; Signal/Noise), parameter such as adjacent area pilot signal level, base station control device requires wireless terminal not carry out new information such as carrier wave switching simultaneously; Received the pseudo-carrier wave instruction of foundation of base station control device by the base station after, set up this pseudo-carrier wave, and this carrier wave of notice master unit is pseudo-carrier wave, master unit carries out taking turn to this pseudo-carrier wave according to the taking turn routing table; Simultaneously, master unit notice expanding element carries out taking turn (referring to comprising under the situation of expanding element) here to this pseudo-carrier wave.In the taking turn process, far-end unit and wireless terminal are wireless connections, return this pseudo-carrier information through wireless terminal and confirm that wireless terminal is whether under by the covering of the far-end of taking turn.
The information that in the measurement report of a terminal to report, comprises pseudo-carrier wave then shows this terminal under by the covering of the far-end unit of taking turn, and the network measure information in this measurement report is exactly corresponding to by the network measure information of the far-end unit of taking turn.The network measure information of this moment is called the first network measure information, the first network measure information
For example comprise: the received signal code power that the terminal measures (Received Signal Code Power; RSCP), the signal quality value that measures of terminal; For example quality indication signal (Signal Quality Incident, SQI), the signal to noise ratio (Ec/Io) behind the spread spectrum.
Step 406: master unit judges according to the first network measure information whether the far-end unit of selecting is weak covering, if, execution in step 409, otherwise execution in step 407.
Wherein, if RSCP is lower than critical index (Key Performance Indication, the KPI) value, and signal quality value is lower than the grade point of setting, then confirms as weak covering of setting.
Further, master unit can report the weak coverage condition of far-end unit operation maintenance center (Operations and Maintenance Center OMC), dispatches processing by OMC.
Step 407: master unit judges whether also to exist the far-end unit that does not have processing, if, repeated execution of steps 404 and subsequent step thereof, otherwise execution in step 408.
Step 408: master unit confirms to optimize end.
Step 409: master unit increases the power output of far-end unit with the step value of setting.
For example, master unit sends the instruction that is used to increase power output to far-end unit after a little less than confirming far-end unit, covering, and after far-end unit receives this instruction, supposes that the step value of setting is δ, then new power output=old power output+δ.
In the above-mentioned flow process, the network measure information of far-end unit is obtained during by taking turn at this far-end unit; After obtaining the network measure information of far-end unit, present embodiment just is optimized according to network measure information during by taking turn with this far-end unit and is example, and is optional, also can be to be optimized processing with all far-end units are all unified again after the taking turn.
Step 410: master unit judges whether far-end unit reaches peak power output, if, execution in step 411, otherwise repeated execution of steps 405 and subsequent step thereof.
Wherein, master unit can be communicated by letter with far-end unit, reads the power output of far-end unit from far-end unit, when power output reaches rated power, confirms to reach peak power output.
Step 411: master unit reports the position that lays that needs to increase the number of far-end unit or adjust far-end unit.
Wherein, master unit can report to OMC.
Further, can also set the taking turn time, after the time of taking turn next time arrives, repeated execution of steps 401～step 411.
