Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
UE reporting measurement reports → base station triggers switching → UE and network side perform switching.
The configuration of mobility parameters determines that UE is from detecting that whether current service cell RLF is suitable to the time interval to Current Serving BTS reporting measurement reports.
The switching of the abnormal scene that MRO pays close attention to mainly contains three classes: switching time, interval was excessive, switching time interval too small and pingpang handoff, wherein, switching time, interval was excessive, that the serving cell signal that UE detects is poor, and the neighbor cell better than this serving cell signal quality can be detected, reported serving BS, and serving BS does not trigger switching in time, cause switching time interval excessive, mobility parameters is to the adjustment of reduction interval switching time, namely the direction adjustment in the reporting measurement reports time interval is reduced, existing mobility parameters adjustment process as shown in Figure 1, comprise:
S101, worsening due to wireless channel environment, and slowly do not receive again the switching command that serving BS issues, there is RLF in Serving cell in UE.
S102, UE send RRC (RadioResource Control to the adjacent base station that signal is stronger than Current Serving BTS, radio resource control) rebuild notice or RLF (Radio LinkFailure, Radio Link Failure) notice, triggers and rebuilds flow process.
After S103, adjacent base station receive RRC reconstruction notice or RLF notice, notify to send from X2 mouth to former serving BS to rebuild notice according to reconstruction notice or RLF, notify this reconstruction event.
After S104, former serving BS receive the reconstruction notice of X2 mouth, namely infer that UE, in the Serving cell of this serving BS, RLF occurs, UE does not trigger measurement report in time, base station is caused to send switching command to UE excessively late, and base station is triggered caused by switching in time, and on this basis, report the direction in the time interval to adjust, to make the timely reporting measurement reports of UE to reduction UE mobility parameters.
But, due to RLF producing cause and not all excessively to cause because of the reporting measurement reports time interval, therefore cause the partial parameters mistuning by occurring under normal scene whole.
Fig. 2 is the embodiment of a kind of parameter processing method of the present invention, comprising:
S201, serving BS receive after reconstruction notice that adjacent base station sends or Radio Link Failure RLF notify, the time difference T_eNB_HO of the time value obtaining the last reception measurement report and the time value issuing switching command.
If this time difference of S202 T_eNB_HO is greater than the first default threshold range Thd_eNB, then do not adjust mobility parameters, this first threshold range Thd_eNB comprises the statistical value of the difference of the time value normally receiving measurement report and the time value issuing switching command.
The parameter processing method that the embodiment of the present invention provides, serving BS receive adjacent base station send reconstruction notice or RLF notice after, directly mobility parameters is not adjusted to reduction RLF direction, to make the timely reporting measurement reports of UE, reject receiving other situations of rebuilding notice or RLF notice except the time interval larger the caused serving BS because of UE reporting measurement reports.When the T_eNB_HO that calculating, transmission etc. because of network side are caused becomes large, no longer mobility parameters is adjusted, thus the accuracy of mobility robust technique can be improved, be conducive to the optimization of the whole network mobility parameters.

At this, if the last time receive UE report cover reason trigger measurement report after, serving BS does not issue corresponding switching command to this UE, then can setting-up time difference T_eNB_HO be infinity.
In addition, if T_eNB_HO is less than the first default threshold range Thd_eNB, then serving BS then adjusts to reduction RLF direction mobility parameters.
