Abstract
The invention provides optimizing handling method and system for abnormal switching. The method comprises the steps of counting the times that switching request messages sent from a source base station are not confirmed by a target base station in a target cell; calculating the ratio of the times that the switching request messages sent by the source base station are not confirmed by the target base station to the times of the switching request messages sent by the source base station to obtain the feedback ratio of the target cell; setting the switching property of the target cell into switching inhibited state if the feedback ratio of the target cell is more than the preset threshold, and synchronously reporting to an operation management center; determining whether the switching property of the target cell is set to be the switching inhibited state by other cells according to the inspection information returned by the operation management center; if so, setting the switching property of the cells adjacent to the target cell into the switching inhibited state. With the adoption of the method, the influence of switching failure on the network key performance index under the abnormal device scene can be reduced.
Description
Technical field
The present invention relates to network communication technology field, particularly relate to a kind of optimized treatment method and system of abnormal switching.
Background technology
In public network, handover success rate is one of most important KPI Key Performance Indicator KPI, is the important indicator of operator's monitoring network quality.Cause the reason of handoff failure a lot, the reason of the network optimization, the reasons such as such as handoff parameter arranges unreasonable, and the network coverage is weak.Also having a kind of is the reason of unit exception, and base station equipment AP layer is abnormal, and radio frequency is normal, terminal can normal searching to community, and there is no abnormality alarming.Concrete handoff procedure can be divided into handoff preparation phase, switching performs and switching completes the stage.Fig. 1 is the X2 handoff procedure (S1 handoff procedure is with reference to agreement) that agreement specifies, as shown in Figure 1, existing switching flow specifically comprises the steps:
Switch set-up procedure:
Source base station Source eNB determines to carry out UE switching according to the measurement report that user UE reports, handover request message HANDOVERREQUEST is initiated to target BS Target eNB, candidate cell can have multiple, and therefore Source eNB may initiate multiple handover request message HANDOVER REQUEST.Target eNB adjudicates after receiving handover request message, switches if accept UE, then reply switching request acknowledgement message HANDOVER REQUEST ACKNOWLEDGE to source base station.
Hand-off execution process:
After the HANDOVER REQUESTACKNOWLEDGE of target BS is collected in former base station, according to certain rule (such as replying the community that the power of response is the highest), send switching command RRC to UE and connect reconfiguration message RRC ConnectionReconfiguration, UE and target BS carry out uplink synchronous, be linked into Target cell, then UE replys RRC connection and has reshuffled message RRC Connection ReconfigurationComplete.
Switch the stage:
Source base station and target BS complete after data switch, and target BS indicates former base station UE context release message UE CONTEXT RELEASE, and so far handoff procedure completes.
Realizing in process of the present invention, inventor finds that in prior art, at least there are the following problems:
In prior art, careful classification is not carried out to the optimization of special screne, do differentiated optimization process, base station equipment application layer is occurred abnormal, and the normal situation of radio frequency, after the normal reporting measurement reports of UE, source base station can initiate HANDOVERREQUEST to target BS, but occurs abnormal due to the access node AP of target BS, can not reply HANDOVER REQUEST ACKNOWLEDGE.Handoff failure, UE can again send measurement and report, and HANDOVER REQUEST is initiated to target BS again in former base station.Again and again, the short time has thousands of secondary failure up to a hundred, affects huge on network key performance indicators KPI.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of optimized treatment method and system of abnormal switching, by judging switching abnormal scene, abnormal situation being occurred for base station equipment application layer and is optimized process, reducing the impact on network key performance indicators KPI.
A kind of abnormal optimized treatment method switched that the present invention proposes, specifically comprises the following steps:

With reference to Fig. 4, show the optimized treatment method flow chart that base station equipment application layer is occurred to for abnormal switching proposed in the embodiment of the present invention; This optimized treatment method flow process performs in the cell-of-origin switched, and each adjacent cell triggers a flow process, and in period of time T, concrete steps are as follows:
1) counting switched, Rule of judgment can be former base station triggers HANDOVERREQUEST, then count N
handover=N
handover+ 1
2) judge that whether switching is failed, if handoff failure, whether the flow process of handoff failure does not reply HANDOVER REQUEST ACKNOWLEDGE, if do not replied, judges to belong to this situation.Counting N
nORESPONSE=N
nORESPONSE+ 1.
3) do you judge that cycle T expires? ratio is calculated: R if expired
targetcelli=N
nORESPONSE/ N
handover
4) R
targetcelliwhether be greater than Th
fail, Th
failcan arrange, if base station applies layer breaks down, the likelihood ratio of the failure that switches is higher, reaches 100%.90% is preferably in the embodiment of the present invention.
5) by the Target cell cell of correspondence
targeswitch attribute be set to forbid switching state nohandover, report operations control center OMC, OMC judges whether that the switch attribute of described Target cell is set to forbid switching state by other communities, if, judge that this community is abnormal, search is all by Target cell cell around
targebe set to the community of adjacent cell, switch attribute corresponding for above-mentioned adjacent cell be set to forbid switching state no handover.
6) operations control center OMC current goal community cell is reported
targehidden failure may be there is.
In the embodiment of the present invention, a timer can also be provided with, after presetting the first timing, switching state is forbidden in releasing, if be set to continuously forbid switching state at the switch attribute presetting described Target cell in the second timing, after being preferably continuous 3 times, be set to forever forbid, report operations control center OMC to carry out abnormality processing to described Target cell, lift a ban until keeper processes extremely.
Period of time T described in the invention process is preferably 15 minutes, and T value can be arranged arbitrarily, and the embodiment of the present invention does not do concrete restriction to this.A kind of abnormal optimized treatment method switched that the embodiment of the present invention provides, by the community of operations control center fast searching and abnormal object community adjacent cell each other, and be set to and forbid switching state, realize the location of fault cells, and then reduce the loss of KPI Key Performance Indicator KPI, reduce the impact on network key performance indicators.
