Below in conjunction with Figure of description, embodiments of the present invention is further illustrated, but the present invention is not limited to downThe embodiment of face.
Embodiment mono-:
As shown in Figure 1, be the schematic flow sheet of base station fault detection method described in the embodiment of the present invention one, needBe noted that described in the embodiment of the present invention one that base station fault detection method can be applied in 3G(The3rdGeneration), in the communication system such as Long Term Evolution (LongTermEvolution, LTE), described sideMethod comprises the following steps:
Step 101: base station fault checkout equipment receives the correspondence that each base station gathers and reports in setting durationThe uplink receiving interfering signal power of community.
Particularly, according to third generation partner program (The3rdGenerationPartnershipProject,3GPP) regulation and stipulation, the network equipment in LTE system, as evolution base station (eNodeB) and terminal are establishedStandby (UE) etc. all has and measures and report to high level the ability of the measurement item specifying in 3GPP specification, instituteState measurement item and comprise the measuring amount for switching with frequency and alien frequencies, the survey for switching between different radio technologyAmount amount, for the measuring amount of timing and for the measuring amount of RRM etc. In the embodiment of the present inventionIn, related measuring amount is mainly uplink receiving interfering signal power (ReceivedInterferencePower, RIP), described RIP is defined as the interference merit in the bandwidth of a Physical Resource Block (PRB)Rate, comprises thermal noise.
Particularly, in this step 101, each base station need to be by set the each base station institute gathering in duration rightAnswer the uplink receiving interfering signal power of community to report described base station fault checkout equipment, wherein, described baseStation failure checkout equipment can be established for operation maintenance center's (OMC-R) equipment or other third parties of webmaster sideStandby, the embodiment of the present invention is not limited in any way this; In addition, it should be noted that, described setting duration needsTo set as the case may be, for example, if real-time or promptness etc. that base station fault is detected requireHeight, can be set to shorter duration by described setting duration, if to base station fault detect real-time orPromptnesses etc. require lower, the duration that can described setting duration is set to grow, the embodiment of the present inventionThis is not also limited in any way.
Further, each base station reports the described uplink receiving interfering signal power collecting base station eventBarrier is when checkout equipment, also needs community number (CellID) and each community of each base station institute respective cellThe information reportings such as the channel number (Earfcn) of corresponding carrier frequency point are given described base station fault checkout equipment,So that base station fault checkout equipment can be each according to the information such as described CellID and the Earfcn difference receivingBase station.
Further, each base station also needs the uplink receiving of the each base station institute respective cell collecting to disturb letterNumber corresponding ascending time slot information reporting of power is to base station fault checkout equipment, and described ascending time slot information canThink the information such as the time slot sequence number (TimeSlotNumber, TSNum) of each ascending time slot, particularly,For LTE communication system, the time slot sequence number of described ascending time slot can be TSNum4.
Step 102: for arbitrary base station, base station fault checkout equipment is by upper from this base station receivingRow receives interfering signal power and averages.
