Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example, the present invention is further elaborated.Only should be appreciated that specific embodiment described herein
Only in order to explain the present invention, it is not intended to limit the present invention.
The present invention proposes the method and apparatus of a kind of miss-configured neighboring cells determined in mobile communication system, in service
Cell measurement to the level value of each community carry out statistical analysis, choose and meet the little of the judgment condition preset
District be the candidate cell of Serving cell to determine miss-configured neighboring cells, improve miss-configured neighboring cells judge accuracy.
Fig. 1 shows the miss-configured neighboring cells determined according to an embodiment of the invention in mobile communication system
The flow chart of method 100.As it is shown in figure 1, the method 100 includes:
In step 110, obtain the level value of each community arrived in Serving cell measurement.Such as, Yong Hushe
The standby level value measuring each community at Serving cell, and by measurement to level value report net by base station
Network side, in order to carry out miss-configured neighboring cells analysis.
Then in step 120, the level value of each community obtained is carried out statistical analysis, choose and meet in advance
If the candidate cell that community is Serving cell of judgment condition.In specific embodiment, described default judgement
Condition include following at least one: the ratio judgement of the pendulous frequency of community and total sampling number, the electricity of community
Level values judgement, unique Cell judgement.In further embodiment, described default judgment condition also includes geography
Judgement.Follow-up will provide detailed introduction for various judgment condition.
Then in step 130, by the community being defined previously as adjacent area of the cell ID of candidate cell Yu acquisition
Mark compares, and by the cell ID of the candidate cell different from the cell ID being defined previously as adjacent area
It is judged to the cell ID of miss-configured neighboring cells.
In this step, the adjacent area number of predefined Serving cell is typically not greater than 32, the neighbour of configuration
Qu Yue is many, and the judgment condition preset should be severeer, and otherwise the adjacent area of redundancy is the most.Such as, little in employing
When the level value in district is adjudicated, corresponding level value threshold requirement is the highest, as shown in table 1 below:
| Adjacent area quantity | Level value (dBm) |
| 0<=n<=10 | >=-90 |
| 10<=n<=20 | >=-88 |
Table 1
In the present embodiment, the adjacent area number being defined previously as Serving cell may be configured as 20.
Hereinafter will be described in detail the specific embodiment of the candidate cell choosing Serving cell under various judgment condition.
Fig. 2 shows the ratio judgment condition of pendulous frequency and the total sampling number using community in step 120
Time idiographic flow.If as in figure 2 it is shown, the pendulous frequency that judgment condition is community preset and total sampling time
When the ratio of number is adjudicated, step 120 farther includes:
In step 121, divide according to default intensity threshold scope residing for the level value measuring the community arrived
Intensity rank.
In this step, the intensity threshold scope preset has N number of, can will fall into default first intensity threshold
The intensity rank of the level value of value scope is set as 1 grade, falls into the electricity of default second intensity threshold scope
The intensity rank of level values is set as 2 grades, other the like, wherein N is the integer more than or equal to 1.
Such as, when certain level value of the community measured is in first default intensity threshold scope, should
Level value is divided into 1 grade.
Then, in step 122, in statistics repetitive measurement, the level value of same community occurs in same intensity level
Other number of times.
As shown in table 2, it is assumed that Serving cell Server Cell receives 3 measurement reports, default intensity altogether
Threshold range has 2(N=2) individual, Times1 represents the number of times of the level value that intensity rank is 1 grade, Times2
Represent the number of times of the level value that intensity rank is 2 grades.
| Serving cell | Measure the community arrived | Times1 | Times2 |
| Server Cell | Test Cell1 | 1 | 2 |
| Server Cell | Test Cell2 | 3 | 5 |
| Server Cell | Test Cell1 | 6 | 7 |
Table 2
Assume that the level value of statistics Test Cell1 occurs in the number of times of 1 grade of intensity, be then equal to: 1+6=7(time).
Then in step 123, total sampling number of same community in statistics repetitive measurement.
In this step, each of this community that the value of total sampling number of same community arrives more than or equal to measurement is strong
The sum of the number of times of the level value of degree rank, such as the Times in table 3.When all level values measured all fall
When entering default intensity threshold scope, Times is equal to the sum of the number of times of the level value of each intensity rank；When
When there is the level value outside default intensity threshold scope in the level value measured, Times is equal to each
The number of times of the level value of intensity rank and with the level value occurred in outside default intensity threshold scope
Number of times sum.
| Serving cell | Measure the community arrived | Times1 | Times2 | Times |
| Server Cell | Test Cell1 | 1 | 2 | 4 |
| Server Cell | Test Cell2 | 3 | 5 | 8 |
| Server Cell | Test Cell1 | 6 | 7 | 13 |
Table 3
Due in 3 measurement reports of table 3, have 2 about Test Cell1, therefore in statistics
During total sampling number of Test Cell1, the Times of 2 measurement reports should be added: 4+13=17(time).
Then, in step 124, the number of times that the level value of calculating community occurs in each intensity rank is little with described
The ratio of total sampling number in district.
Preferably, when ratio calculated, one can be given in advance according to the sequencing of the intensity rank of level value
Fixed weights.Assuming that the intensity threshold scope preset has N number of, N is the integer more than or equal to 1, preferably
Ground, N is equal to 2,4,6.
Whether such as, during N=2, can use the ratio in judgement community of following formula is the candidate adjacent of Serving cell:
(Times1+Times2)/total sampling number.Such as, as shown in table 3, the level value of Test Cell1 occurs
At the number of times of each intensity rank with the ratio of total sampling number of this Test Cell1 it is: (7+9)
/17=0.94.Whether during N=4, using the ratio in judgement community of following formula is the candidate adjacent of Serving cell:
[(Times1+Times2) * 1+ (Times3+Times4) * 0.8]/total sampling number.
The most such as, during N=6, measure the intensity rank of the level value of community Test Cell1 at Serving cell
Occur in 1 grade, 2 grades, 3 grades, 4 grades, 5 grades, the number of times of 6 grades be respectively Times1, Times2,
Times3, Times4, Times5, Times6, as shown in table 4:
| Measure the community arrived | Times1 | Times2 | Times3 | Times4 | Times5 | Times6 |
| Test Cell1 | 1 | 2 | 3 | 4 | 5 | 6 |
Table 4
Whether when N=6, using this community of ratio in judgement of following formula is the candidate adjacent of Serving cell:
[(Times1+Times2) * 1+ (Times3+Times4) * 0.8+ (Times5+Times6) * 0.6]/total sampling time
Number.
The most such as, dividing in simple network in adjacent area level, can only calculate the level value ranking of community is the
The ratio of total sampling number of number of times when 1 and this community, joins the accuracy of judgement improving adjacent area leakage.
Then, in step 125, the candidate cell of Serving cell is chosen based on calculated ratio.One tool
In body embodiment, this ratio can be compared with the threshold value preset, and at this ratio more than the threshold value preset
Time judge that the community of correspondence is as the candidate cell of Serving cell.In another specific embodiment, can be by each community
Described ratio be ranked up, and choose preceding a number of community of sorting as the candidate of Serving cell
Community.
Embodiment when Fig. 3 shows the level value judgment condition using community in step 120 concrete
Flow process.If during as it is shown on figure 3, the level value that judgment condition is community preset is adjudicated, step 120 can be entered
One step includes:
Step 121 ' in, the level value of each community obtained is ranked up, and adds up repetitive measurement and obtain
To the level value of same community come the sum of N number of level value of front 1 to N name, wherein N be integer and
1≤N≤6。
Then step 122 ' in, compare the sum of N number of level value of each community, and choose ranking at front M
M community as the candidate adjacent of Serving cell, wherein M is integer and 1≤M≤N.
The tool of another embodiment when Fig. 4 shows the level value judgment condition using community in step 120
Body flow process, unlike the embodiment shown in Fig. 3, adds up level value flat of community in this embodiment
Average compares.As shown in Figure 4, if the meansigma methods of the level value that judgment condition is community preset is sentenced
Time certainly, step 120 can farther include:
Step 121 " in, the level value of each community obtained is ranked up, and adds up repetitive measurement and obtain
To the level value of same community come the average of N number of level value of front 1 to N name, wherein N is integer
And 1≤N≤6.
Then step 122 " in, compare the average of the described level value of each community, and choose ranking front
M the community of M is as the candidate adjacent of Serving cell, and wherein M is integer and 1≤M≤N.
Preferably, in adjacent area level divides simple network, can be by only comparing the level value of different districts
Ranking is that level value size when the 1st is to choose the candidate adjacent of Serving cell.
Additionally, when default judgment condition is unique Cell judgement, step 120 can farther include: system
The number of the level value of the community that meter obtains, if the number of the level value of the community obtained is 1, then judging should
Community is the candidate adjacent of Serving cell.For example, it is assumed that subscriber equipment generally can measure the electricity of 6 communities
Level values, but sometimes due to the stop of other objective factors, such as certain floor, 1 community can only be measured
Level value, then illustrate that this community is likely to the first-selection of switching, therefore Ke Jianggai community is judged to service little
The candidate adjacent in district.
The present invention chooses the candidate adjacent of Serving cell by judgment condition described above, it is possible to compare
Find out miss-configured neighboring cells exactly.In further embodiment of the present invention, by adding the judgement bar of geography judgement
Part, can get rid of the problem covered.Such as, Serving cell H and community G relatively far apart, but passes through
The ratio judgement of the pendulous frequency of community and total sampling number and/or the level value judgement of community and/or only
After the judgement of one community judgement, still judge the community G candidate adjacent as Serving cell H, then can be by ground
The community being mistaken for candidate adjacent is found out in reason judgement, improves the accuracy that candidate adjacent judges.
Preferably, at the ratio judgement of pendulous frequency with total sampling number using community, the level value of community
In judgement, the judgement of unique Cell judgement and geographical judgement, at least two judgment condition selects Serving cell
During candidate adjacent, in advance each judgment condition can be composed in advance weights, and calculate corresponding weights and,
Finally select weights and the candidate adjacent that community is Serving cell stood out.
In specific embodiment, the judgment condition hierarchy based on community of the geographical judgement of the present invention.Fig. 5
Showing that community is in the schematic diagram of the Serving cell difference number of plies, in Figure 5, it is little that community A is positioned at service
1st floor in district, community B is positioned at the 2nd layer of Serving cell, and community C is positioned at the 3rd layer of Serving cell
