Embodiment one
The number that comprises the measurement report of same adjacent area in the number of times of the UE reporting measurement reports of local terminal residential quarter basis in its coverage in this example and the measurement report that reports obtains the coverage rate of this adjacent area in described residential quarter.The coverage of this routine small area refers to the actual coverage of residential quarter, but not the theoretical coverage of usual indication.The difference that the below covers with example explanation theoretical coverage and reality:
Suppose to exist two residential quarter A and B that neighbouring relations are arranged, and the covering radius of residential quarter A and B all is 1000 meters, the theoretical coverage of 1000 meters residential quarters saying here, that is to say that 1000 meters position UE still can access conversation in the distance base station in theory, but the actual middle UE that arranges net may be in the distance base station 800 meters position just access or switched to other residential quarters, so the radius of the actual coverage of above-mentioned two minizones should be 800 meters.From the mobility angle of UE, the actual covering of minizone is more paid close attention in the base station.The measurement report that UE in this routine small area uploads refers to the handover measurement report.
This example is take above-mentioned residential quarter A as the local terminal residential quarter, and above-mentioned residential quarter B is that an adjacent area B in a plurality of adjacent areas of residential quarter A under a certain frequency is example, and the present invention will be further described, sees also Fig. 1;
Receive the measurement report that UE reports in the local terminal residential quarter A under certain frequency, and obtain the number of times of the interior UE reporting measurement reports under this frequency of A in the local terminal residential quarter;
Resolve the described measurement report that reports, to obtain the number that comprises the measurement report of same adjacent area B in the measurement report that reports;
Obtain the coverage rate of adjacent area B in the A of local terminal residential quarter according to the number that comprises 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 residential quarter and the measurement report that reports.Wherein, obtaining the coverage rate of adjacent area B in the A of local terminal residential quarter according to the number that comprises 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 residential quarter and this reporting measurement reports comprises:
Measurement report is set reports threshold value, be provided for simultaneously adding up UE and upload the first count value of measurement report number of times and be used for the second count value that statistics includes the measurement report number of described adjacent area B;
UE uploads the one-shot measurement report in the local terminal residential quarter under this frequency, and the first count value increases by 1, and when comprising adjacent area B simultaneously in judging this measurement report, the second count value increases by 1;
When the first count value equals measurement report and reports threshold value, 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 residential quarter.
When in judging this measurement report, comprising adjacent area B, can judge according to the neighboring cell signal quality threshold value that in measurement report is set reports the step of threshold value, arranges simultaneously, the adjacent area B signal quality that comprises in measurement report judges just that greater than the neighboring cell signal quality threshold value this measurement report comprises this adjacent area B; Otherwise, be judged to be this measurement report and do 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 frequently handover measurement configuration, the handover measurement configuration of different system, so the method that this example provides can automatically be found and optimize with frequently, alien frequencies, the adjacent area covering relation of different system, do not distinguish the wireless access standard, can judge the inner (TDD-LTE of LTE, FDD-LTE) with frequently, covering relation between the alien frequencies adjacent area and various standard (UTRA-TDD, UTRAN-FDD, CDMA-HRPD, CDMA-1xRTT, GERAN) covering relation between the adjacent area; And the measurement report that this example is uploaded according to UE obtains the adjacent area coverage rate, has shielded the complexity of wireless system, and the most real covering relation that has reacted between the residential quarter realizes that simply operation cost is low.
This example also provides a kind of method of obtaining the adjacent area covering relation on the basis of the coverage rate of having obtained the adjacent area by said method, specific as follows:
Local terminal residential quarter A and with it corresponding adjacent area B obtain first coverage rate and local terminal residential quarter A second coverage rate among adjacent area Bs of adjacent area B in the A of local terminal residential quarter according to aforesaid method respectively;
Local terminal residential quarter A according to above-mentioned the first coverage rate and the second coverage rate obtains and adjacent area B between covering relation.
In this example, local terminal residential quarter A also comprises the step that sends it to adjacent area B after obtaining described the first coverage rate; Equally, after adjacent area B obtains described the second coverage rate, also comprise the step that sends it to local terminal residential quarter A, between the residential quarter, send above-mentioned coverage rate and constantly select to transmit by S1 interface, X2 interface or station communication interface according to actual conditions.
Covering relation in this example between the adjacent area comprises same covering relation, involved covering relation, comprises covering relation and adjacent covering relation.See also Fig. 2-Fig. 5,
For same covering relation, as shown in Figure 2, reside in the UE reporting measurement reports of residential quarter A and exist the probability of adjacent area B to be tending towards 100%, reside in simultaneously in the UE reporting measurement reports of residential quarter B and exist the probability of adjacent area A to be tending towards 100%.
For involved covering relation, as shown in Figure 3, residing in the UE reporting measurement reports of residential quarter A exists the probability of B to be tending towards 100%, reside in the UE reporting measurement reports of residential quarter B and exist the probability of adjacent area A should be tending towards a certain fixed value Coverage, the size of Coverage depends on the ratio that two cell coverage areas overlap;
For comprising covering relation, as shown in Figure 4, similar in inclusion relation, residing in to change on the UE of residential quarter B exists the probability of adjacent area A to be tending towards 100% in the measurement report, reside in the UE reporting measurement reports of residential quarter A and exist the probability of adjacent area B should be tending towards a certain fixed value Coverage, the size of Coverage depends on the ratio that two cell coverage areas overlap;
For adjacent covering relation, as shown in Figure 5, the UE reporting measurement reports that resides among the A of residential quarter exists the probability of adjacent area B to be tending towards a certain fixed value Coverage1, and the UE reporting measurement reports that resides among the B of residential quarter exists the probability of A to be tending towards a certain fixed value Coverage2; The size of Coverage1 and Coverage2 depends on the ratio that two cell coverage areas overlap.
By top analysis, if definition Cover Characteristics two tuples:
The coverage rate of adjacent area B among Cover Characteristics＜residential quarter A, the coverage rate of adjacent area A among the B of residential quarter 〉
Then have
Same Cover Characteristics＜convergence 100%, convergence 100% 〉
Involved relationship characteristic＜convergence 100%, convergence Coverage 〉
Inclusion relation feature＜convergence Coverage, convergence 100% 〉

Therefore, can distinguish each adjacent area covering relation by above-mentioned Cover Characteristics in this example.Still take above-mentioned local terminal residential quarter A and adjacent area B as example, this example can be before obtaining above-mentioned the first coverage rate and the second coverage rate at local terminal residential quarter A, also comprise coverage rate maximum threshold step is set, local terminal residential quarter A obtains after the first coverage rate and the second coverage rate, the first coverage rate and the second coverage rate and coverage rate maximum threshold are compared, according to comparative result obtain and adjacent area B between covering relation, specific as follows:
Local terminal residential quarter A compares the first coverage rate and the second coverage rate and coverage rate maximum threshold, if all greater than the coverage rate maximum threshold, show that then the coverage rate of adjacent area B in the A of local terminal residential quarter levels off to 100%, the coverage rate of local terminal residential quarter A in the B of adjacent area also levels off to 100% simultaneously, and therefore the covering relation between this moment local terminal residential quarter A and adjacent area B is with covering.
Local terminal residential quarter A compares the first coverage rate and the second coverage rate and coverage rate maximum threshold, if the first coverage rate is greater than the coverage rate maximum threshold, the second coverage rate is less than the coverage rate maximum threshold, show that then the coverage rate of adjacent area B in the A of local terminal residential quarter levels off to 100%, the local terminal residential quarter coverage rate of A in the B of adjacent area is lower than the coverage rate maximum threshold, therefore the covering relation between this moment local terminal residential quarter A and adjacent area B is involved covering relation, and namely local terminal residential quarter A is contained among the B of adjacent area.
Local terminal residential quarter A compares the first coverage rate and the second coverage rate and coverage rate maximum threshold, if the first coverage rate is less than the coverage rate maximum threshold, the second coverage rate is greater than the coverage rate maximum threshold, show that then the coverage rate of adjacent area B in the A of local terminal residential quarter is lower than the coverage rate maximum threshold, the local terminal residential quarter coverage rate of A in the B of adjacent area levels off to 100%, therefore the covering relation between this moment local terminal residential quarter A and adjacent area B is for comprising covering relation, and namely local terminal residential quarter A comprises among the B of adjacent area.
Local terminal residential quarter A compares the first coverage rate and the second coverage rate and coverage rate maximum threshold, if the first coverage rate is less than the coverage rate maximum threshold, the second coverage rate is also less than the coverage rate maximum threshold, show that then the coverage rate of adjacent area B in the A of local terminal residential quarter is lower than the coverage rate maximum threshold, the local terminal residential quarter coverage rate of A in the B of adjacent area also is lower than the coverage rate maximum threshold, therefore the covering relation between this moment local terminal residential quarter A and adjacent area B is adjacent covering relation, and namely there are the zone that not exclusively overlaps in local terminal residential quarter A and adjacent area B.
Local terminal residential quarter A in this example obtain and adjacent area B between covering relation after, also can comprise according to the covering relation that obtains upgrade and adjacent area B between covering relation, specific as follows:
Local terminal residential quarter A judge with adjacent area B between current covering relation whether identical with the covering relation that described local terminal residential quarter obtains, as no, then it is updated to the covering relation between that above-mentioned steps obtains and the adjacent area B.
Simultaneously, in order further effectively to obtain the covering relation between the adjacent area, the coverage rate minimum threshold also can be set the less adjacent area of coverage rate is deleted the dependable with function of the adjacent area covering relation that assurance is obtained in this example.Concrete, can be before local terminal residential quarter A obtains the first coverage rate, the coverage rate minimum threshold is set, local terminal residential quarter A obtains after the first coverage rate, described the first coverage rate and the described coverage rate minimum threshold that obtain are compared, as less than as described in the coverage rate minimum threshold, then with adjacent area B deletion, namely this moment, adjacent area B no longer was the adjacent area of local terminal residential quarter A.
Adjacent area in this example and local terminal residential quarter be according to exchanging, and namely when obtaining the adjacent area covering relation of residential quarter A, residential quarter A is the local terminal residential quarter, and residential quarter B is the adjacent area of local terminal residential quarter A; Equally, when obtaining the adjacent area covering relation of residential quarter B, residential quarter B is the local terminal residential quarter, and residential quarter A is the adjacent area of local terminal residential quarter B.
The present invention also provides a kind of device be used to obtaining the adjacent area coverage rate, and this device comprises for the statistical module that obtains the adjacent area coverage rate according to aforesaid method.
Further, the present invention also provides a kind of system's (system of this example can be used as the base station) for obtaining the adjacent area covering relation, see also Fig. 6, this system comprises the aforesaid adjacent area coverage rate device that obtains, also comprise the R-T unit and the processing unit that are connected with this device, R-T unit also is connected with processing unit simultaneously, and R-T unit be used for to send the coverage rate that the local terminal residential quarter obtains and receives the coverage rate that the adjacent area sends over.Processing unit is used for the coverage rate of obtaining according to the local terminal residential quarter and receives coverage rate that the adjacent area sends over obtaining covering relation between local terminal residential quarter and the adjacent area, specific as follows: processing unit compares the coverage rate that coverage rate and the described R-T unit of local terminal residential quarter receives respectively with the coverage rate max threshold of setting, and obtains covering relation between described local terminal residential quarter and the adjacent area according to comparative result.
Further, system in this example also comprises the switch decision device that is connected with above-mentioned statistic device and the UE that is connected with this switch decision device, the switch decision device is used for judgement UE and whether satisfies switching condition, as satisfying, then notify UE can upload the handover measurement report, comprise at least the ID of the adjacent area that detects and the signal strength information of adjacent area in this handover measurement report.UE in this example uploads handover measurement, and to report to the base station be the edge that occurs in the residential quarter.Selecting one in the candidate cell that the base station comprises from the handover measurement report switches.
Embodiment two
As from the foregoing, the measurement report that method provided by the invention, Apparatus and system can utilize the UE in the residential quarter to report obtains the coverage rate of adjacent area, and then obtain covering relation between the adjacent area, and can automatically find and optimize the adjacent area covering relation with frequency, alien frequencies, different system, the below respectively take automatic discovery, the present invention will be further described as example to optimize the adjacent area covering relation of same frequency, alien frequencies, different system:
Define above-mentioned each threshold value, as follows:
It is MEAS_RPT_NUM_THRELD that the definition measurement report reports thresholding;
Definition neighboring cell signal quality thresholding is CELL_RSRP_THRELD;
Definition adjacent area detection probability wealthy family is limited to COVERAGE_HIGH;
Definition adjacent area detection probability low threshold is COVERAGE_LOW;
Defining the first count value is HO_FREQ_MEAS_RPT_COUNT;
Defining the second count value is HO_NBR_MEASRPT_COUNT;
After receiving the measurement report that UE uploads under certain frequency, HO_FREQ_MEAS_RPT_COUNT adds 1; If this measurement report comprises this adjacent area, and signal quality is greater than CELL_RSRP_THRELD, and then HO_NBR_MEASRPT_COUNT adds 1, otherwise HO_NBR_MEASRPT_COUNT is constant;
When HO_FREQ_MEAS_RPT_COUNT equals MEAS_RPT_NUM_THRELD, stop statistics, calculate according to the method described above coverage rate Coverage;
Coverage＝HO_NBR_MEASRPT_COUNT/HO_FREQ_MEAS_RPT_COUNT；
Or Coverage=HO_NBR_MEASRPT_COUNT/MEAS_RPT_NUM_THRELD;
Calculate according to the method described above respectively adjacent two adjacent areas with respect to the other side's coverage rate; If coverage rate Coverage, thinks then that coverage rate levels off to 100% greater than COVERAGE_HIGH adjacent area detection probability high threshold, if coverage rate Coverage is lower than COVERAGE_LOW, then can be with this adjacent area deletion.The below respectively take automatic discovery, the present invention will be further described as example to optimize adjacent area covering relation with frequency, alien frequencies, different system:
One, to add LTE alien frequencies adjacent area covering relation as the example explanation: suppose to exist each other the other side adjacent area of residential quarter A and residential quarter B;
1. initialization MEAS_RPT_NUM_THRELD=10000; CELL_RSRP_THRELD=-95db; HO_FREQ_MEAS_RPT_COUNT=0; HO_NBR_MEAS_RPT_COUNT=0; COVERAGE_HIGH=95%; COVERAGE_LOW=5%;
2.UE access network, base station issue the alien frequencies handover measurement and dispose to UE;
3.UE after satisfying switching condition measurement report is issued the base station, the switch decision device in the base station issues measurement report be used to the device that obtains the adjacent area coverage rate;
4. obtain the device of adjacent area coverage rate and receive measurement report, HO_FREQ_MEAS_RPT_COUNT adds 1, if the adjacent area quality is greater than CELL_RSRP_THRELD then HO_NBR_MEAS_RPT_COUNT adds 1;
5. after the device that obtains the adjacent area coverage rate finds that HO_FREQ_MEAS_RPT_COUNT is added to MEAS_RPT_NUM_THRELD, calculate according to the method described above the probability that this adjacent area reports;
For example: HO_FREQ_MEAS_RPT_COUNT=10000, HO_NBR_MEAS_RPT_COUNT=9800, according to formula 1, Coverage=98% is greater than COVERAGE_HIGH; Cover Characteristics two tuples: the coverage rate of adjacent area B among Cover Characteristics＜residential quarter A, the coverage rate of adjacent area A among the B of residential quarter〉in, the coverage rate of adjacent area B levels off to 100% (supposing that this coverage rate is the coverage rate of residential quarter B in the A of residential quarter) among the A of residential quarter;
6. if residential quarter A and residential quarter B are the adjacent areas under the same base station, the probability that is reported by the local terminal residential quarter by residential quarter, this cell notification opposite end by residential quarter, communication notifications opposite end in the base station; If this adjacent area is not have the X2 mouth between adjacent area under the different base station and two base stations, the probability that is reported by this residential quarter by S1 mouth notice residential quarter, opposite end; If this adjacent area is between adjacent area under the different base station and two base stations X2 mouth to be arranged, the probability that is reported by this residential quarter by X2 mouth notice residential quarter, opposite end;
7. residential quarter, opposite end (i.e. the adjacent area B corresponding with local terminal residential quarter A) calculates coverage rate according to local terminal residential quarter method, and coverage rate is mail to the local terminal residential quarter, if reporting neighboring cell A ratio is 50% among the B of residential quarter, and residential quarter A then, residential quarter B satisfies:
Involved relationship characteristic＜convergence 100%, 50% 〉, i.e. residential quarter A covering is less, and residential quarter B covers larger, the part of residential quarter A coverage cell B, residential quarter A is included among the B of residential quarter;
8. residential quarter A judges whether the covering relation between current and the residential quarter B is involved covering relation, as no, it is updated to involved covering relation.
Two, to add LTE homogeneous-frequency adjacent-domain covering relation as the example explanation: suppose to exist each other the other side adjacent area of residential quarter A and residential quarter B;
1. initialization MEAS_RPT_NUM_THRELD=10000; CELL_RSRP_THRELD=-95db; HO_FREQ_MEAS_RPT_COUNT=0; HO_NBR_MEAS_RPT_COUNT=0; COVERAGE_HIGH=95%; COVERAGE_LOW=5%;
2.UE access network, base station issue with the frequency handover measurement and dispose to UE;
3.UE after satisfying switching condition measurement report is issued the base station, the switch decision device in the base station issues measurement report be used to the device that obtains the adjacent area coverage rate;
4. obtain the device of adjacent area coverage rate and receive measurement report, HO_FREQ_MEAS_RPT_COUNT adds 1, if the adjacent area quality is greater than CELL_RSRP_THRELD then HO_NBR_MEAS_RPT_COUNT adds 1;
5. after the device that obtains the adjacent area coverage rate finds that HO_FREQ_MEAS_RPT_COUNT is added to MEAS_RPT_NUM_THRELD, calculate according to the method described above the probability that this adjacent area reports;
For example: HO_FREQ_MEAS_RPT_COUNT=10000, HO_NBR_MEAS_RPT_COUNT=2000, according to formula 1, Coverage=20% is less than COVERAGE_HIGH, greater than COVERAGE_LOW; Cover Characteristics two tuples:
