Particularly, base station is self-inspection first, see if there is unnecessary carrier channel to set up pseudo-carrier wave, if have, then feed back ready, notify master unit simultaneously, whether there is unnecessary carrier channel to set up pseudo-carrier wave, if have, then feed back ready, notify far-end unit simultaneously, whether there is unnecessary carrier channel to set up pseudo-carrier wave, if have, then feed back ready, when above-mentioned four equipment are not (if having expanding element, be three equipment) all ready after, can set up pseudo-carrier wave, wherein any one is false, and returns and can not perform data acquisition.
Step S4, sets up pseudo-carrier wave;
Step S5, imports far-end unit indoor distribution position data;
Particularly, import the location database of far-end unit at indoor distribution, this location database is such as the location database in previous embodiment one.
Step S6, sets up taking turn routing table;
Particularly, the idiographic flow setting up taking turn routing table is identical with previous embodiment two, so place repeats no more.
Step S7, starts taking turn;
Step S8, according to the taking turn routing table set up, determines certain far-end unit;
Step S9, data acquisition, gather the RSCP of MS, SNR or Ec/Io of MS, neighbor pilot signals and intensity, link setup traffic data (data service can be converted according to speed) and the received signal strength indicator (ReceivedSignalStrengthIndication, RSSI) of far-end unit or the frequency spectrum data etc. of received total wideband power (ReceivedTotalWidebandPower, RTWP) and far-end unit.
Particularly, after the far-end unit determined by step S8 outwards launches pseudo-carrier wave, carry out data acquisition, obtain the upward signal that MS sends, and according to whether carrying the pseudo-carrier wave of this poll transmission in upward signal, judge whether MS is positioned at the coverage of the first far-end unit, and combine the location database set up in advance, then can determine the physical location of this mobile radio station.Thus, the network performance data of respective chambers position is namely can be used as according to the performance data relevant to this MS collected;
Step S10, stores data by prescribed form;
Step S11, judges whether the far-end unit of this taking turn is last, if not, then returns and performs step S8; If so, then data acquisition terminates, and according to the time cycle of software design patterns, can wait for that data acquisition starts next time.
