Embodiment one
Local terminal community in this example obtains the coverage rate of this adjacent area in described community according to the number comprising the measurement report of same adjacent area in the number of times of the UE reporting measurement reports in its coverage and the measurement report that reports.The coverage of this routine small area refers to the actual coverage of community, but not the theoretical coverage of usual indication.With example, theoretical coverage and the actual difference covered are described below:
Suppose that existence two has community A and B of neighbouring relations, and the covering radius of community A and B is all 1000 meters, the theoretical coverage of the 1000 meters of communities said here, that is still call can be accessed at the position UE of distance 1000 meters, base station in theory, but UE may just access in the position of distance 800 meters, base station or be switched to other communities, so the radius of the actual coverage of above-mentioned two minizones should be 800 meters in actual arranging net.From the mobility angle of UE, the actual covering of minizone is more paid close attention in base station.The measurement report that UE in this routine small area uploads refers to that handover measurement is reported.
This example is with above-mentioned community A for local terminal community, and above-mentioned community B is an adjacent area B in multiple adjacent areas of community A under a certain frequency is example, and the present invention will be further described, refers to Fig. 1;
Receive the measurement report that in the A of local terminal community, UE reports under certain frequency, and obtain the number of times of UE reporting measurement reports under this frequency in A in local terminal community;
The measurement report reported described in parsing, to obtain the number comprising the measurement report of same adjacent area B in the measurement report that reports;
Number according to comprising the measurement report of adjacent area B in the number of times of UE reporting measurement reports under this frequency in the A of local terminal community and the measurement report that reports obtains the coverage rate of adjacent area B in the A of local terminal community.Wherein, obtain the coverage rate of adjacent area B in the A of local terminal community according to the number comprising the measurement report of adjacent area B in the number of times of UE reporting measurement reports under this frequency in the A of local terminal community and this reporting measurement reports to comprise:
Measurement report is set and reports threshold value, arrange simultaneously and upload the first count value of measurement report number of times and the second count value for adding up the measurement report number including described adjacent area B for adding up UE;
In local terminal community, UE uploads one-shot measurement report under this frequency, and the first count value increases by 1, and simultaneously when judging to comprise adjacent area B in this measurement report, the second count value increases by 1;
When the first count value equal measurement report report threshold value time, the second current count value is reported threshold value divided by measurement report or divided by the first current count value, obtains the coverage rate of adjacent area B in the A of local terminal community.
When judging to comprise adjacent area B in this measurement report, can according to reporting the neighboring cell signal quality threshold value arranged in the step of threshold value to judge arranging measurement report simultaneously, when the adjacent area B signal quality comprised in measurement report is greater than neighboring cell signal quality threshold value, just judge that this measurement report comprises this adjacent area B; Otherwise, be judged to be that this measurement report does not comprise adjacent area B.
The measurement configuration reporting measurement reports that UE in this routine small area issues according to LTE, wherein said measurement configuration can comprise the configuration of alien frequencies handover measurement, with handover measurement configuration frequently, different systematic evaluation measures configuration, therefore the method that this example provides automatically can find and optimize with frequently, alien frequencies, the adjacent area covering relation of different system, do not distinguish wireless access standard, LTE inside (TDD-LTE can be judged, FDD-LTE) with frequently, covering relation between alien frequencies adjacent area and various standard (UTRA-TDD, UTRAN-FDD, CDMA-HRPD, CDMA-1xRTT, GERAN) covering relation between adjacent area, and the measurement report that this example is uploaded according to UE obtains adjacent area coverage rate, shields the complexity of wireless system, has reacted the covering relation between community the most really, realize simple, operation cost is low.
This example, on the basis of coverage rate being obtained adjacent area by said method, additionally provides a kind of method obtaining adjacent area covering relation, specific as follows:
Local terminal community A and adjacent area B corresponding with it obtains first coverage rate of adjacent area B in the A of local terminal community and second coverage rate of local terminal community A in the B of adjacent area according to method as above respectively;
Local terminal community A obtains the covering relation between the B of adjacent area according to above-mentioned first coverage rate and the second coverage rate.
In this example, local terminal community A, after obtaining described first coverage rate, also comprises the step sending it to adjacent area B; Equally, after adjacent area B obtains described second coverage rate, also comprise the step sending it to local terminal community A, send between cells the above-mentioned coverage rate moment according to actual conditions select forwarded by S1 interface, X2 interface or station communication interface.
Covering relation in this example between adjacent area comprises same covering relation, involved covering relation, comprises covering relation and adjacent covering relation.Refer to Fig. 2-Fig. 5,
For same covering relation, as shown in Figure 2, reside in the probability that there is adjacent area B in the UE reporting measurement reports of community A and be tending towards 100%, reside in the probability that there is adjacent area A in the UE reporting measurement reports of community B simultaneously and be tending towards 100%.
For involved covering relation, as shown in Figure 3, reside in the probability that there is B in the UE reporting measurement reports of community A and be tending towards 100%, reside in the size that the probability that there is adjacent area A in the UE reporting measurement reports of community B should be tending towards a certain fixed value Coverage, Coverage and depend on the ratio that two cell coverage areas overlap;
For comprising covering relation, as shown in Figure 4, similar in inclusion relation, the UE residing in community B changes in measurement report the probability that there is adjacent area A and is tending towards 100%, reside in the size that the probability that there is adjacent area B in the UE reporting measurement reports of community A should be tending towards a certain fixed value Coverage, Coverage and depend on the ratio that two cell coverage areas overlap;
For adjacent covering relation, as shown in Figure 5, the probability that resident UE reporting measurement reports in cell a exists adjacent area B is tending towards a certain fixed value Coverage1, and the probability that the UE reporting measurement reports resided in the B of community exists A is tending towards a certain fixed value Coverage2; The size of Coverage1 and Coverage2 depends on the ratio that two cell coverage areas overlap.
By analysis above, if definition Cover Characteristics two tuple:
The coverage rate of adjacent area B in the A of Cover Characteristics < community, the coverage rate > of adjacent area A in the B of community
Then have

Therefore, each adjacent area covering relation is distinguished by above-mentioned Cover Characteristics in this example.Still for above-mentioned local terminal community A and adjacent area B, this example can before obtaining above-mentioned first coverage rate and the second coverage rate at local terminal community A, also comprise and coverage rate maximum threshold step is set, after local terminal community A obtains the first coverage rate and the second coverage rate, first coverage rate and the second coverage rate and coverage rate maximum threshold are compared, the covering relation between the B of adjacent area is obtained according to comparative result, specific as follows:
First coverage rate and the second coverage rate and coverage rate maximum threshold compare by local terminal community A, if be all greater than coverage rate maximum threshold, then show that the coverage rate of adjacent area B in the A of local terminal community levels off to 100%, the coverage rate of local terminal community A in the B of adjacent area also levels off to 100% simultaneously, and the covering relation therefore now between local terminal community A and adjacent area B is with covering.
First coverage rate and the second coverage rate and coverage rate maximum threshold compare by local terminal community A, if the first coverage rate is greater than coverage rate maximum threshold, second coverage rate is less than coverage rate maximum threshold, then show that the coverage rate of adjacent area B in the A of local terminal community levels off to 100%, the coverage rate of local terminal community A in the B of adjacent area is lower than coverage rate maximum threshold, therefore the covering relation now between local terminal community A and adjacent area B is involved covering relation, and namely local terminal community A is contained in the B of adjacent area.
First coverage rate and the second coverage rate and coverage rate maximum threshold compare by local terminal community A, if the first coverage rate is less than coverage rate maximum threshold, second coverage rate is greater than coverage rate maximum threshold, then show that the coverage rate of adjacent area B in the A of local terminal community is lower than coverage rate maximum threshold, the local terminal community coverage rate of A in the B of adjacent area levels off to 100%, therefore the covering relation now between local terminal community A and adjacent area B is for comprising covering relation, and namely local terminal community A comprises in the B of adjacent area.
First coverage rate and the second coverage rate and coverage rate maximum threshold compare by local terminal community A, if the first coverage rate is less than coverage rate maximum threshold, second coverage rate is also less than coverage rate maximum threshold, then show that the coverage rate of adjacent area B in the A of local terminal community is lower than coverage rate maximum threshold, the coverage rate of local terminal community A in the B of adjacent area is also lower than coverage rate maximum threshold, therefore the covering relation now between local terminal community A and adjacent area B is adjacent covering relation, and namely local terminal community A and adjacent area B exists the region not exclusively overlapped.
Local terminal community A in this example, after obtaining the covering relation between the B of adjacent area, also can comprise according to the covering relation between the covering relation renewal obtained with adjacent area B, specific as follows:
Whether local terminal community A judges identical with the covering relation that described local terminal community obtains with the current covering relation between the B of adjacent area, as no, is then updated to the covering relation between that above-mentioned steps obtains and adjacent area B.
Meanwhile, in order to the covering relation further between effective acquisition adjacent area in this example, coverage rate minimum threshold also can be set and delete with the adjacent area less to coverage rate, ensure the dependable with function of the adjacent area covering relation obtained.Concrete, can before local terminal community A obtains the first coverage rate, coverage rate minimum threshold is set, after local terminal community A obtains the first coverage rate, described first coverage rate obtained and described coverage rate minimum threshold are compared, as coverage rate minimum threshold as described in being less than, then deleted by adjacent area B, namely now adjacent area B is no longer the adjacent area of local terminal community A.
Adjacent area in this example and local terminal community are according to exchanging, and namely when obtaining the adjacent area covering relation of community A, community A is local terminal community, and community B is the adjacent area of local terminal community A; Equally, when obtaining the adjacent area covering relation of community B, community B is local terminal community, and community A is the adjacent area of local terminal community B.
Present invention also offers a kind of device for obtaining adjacent area coverage rate, this device comprises the statistical module for obtaining adjacent area coverage rate according to method as above.
Further, present invention also offers a kind of system (system in this example can be used as base station) for obtaining adjacent area covering relation, refer to Fig. 6, this system comprises acquisition adjacent area as above coverage rate device, also comprise the R-T unit and processing unit that are connected with this device, R-T unit is also connected with processing unit simultaneously, the coverage rate that R-T unit sends over for the coverage rate and reception adjacent area sending the acquisition of local terminal community.The coverage rate that processing unit is used for sending over according to coverage rate and the reception adjacent area of the acquisition of local terminal community obtains the covering relation between local terminal community and adjacent area, specific as follows: the coverage rate that the coverage rate of local terminal community and described R-T unit receive by processing unit compares with the coverage rate max threshold of setting respectively, obtains the covering relation between described local terminal community and adjacent area according to comparative result.
Further, system in this example also comprises the switch decision device be connected with above-mentioned statistic device and the UE be connected with this switch decision device, whether switch decision device meets switching condition for adjudicating UE, as met, then notify that UE can upload handover measurement report, in the report of this handover measurement, at least comprise the ID of the adjacent area detected and the signal strength information of adjacent area.UE in this example uploads handover measurement, and to be reported to base station be the edge occurring in community.Select one in the candidate cell that base station comprises from handover measurement report to switch.
