Embodiment
(1) division principle of cell cluster
1) scale bunch
Cell cluster should be of certain scale, be difficult for excessive also be difficult for too small, the size implication be not singly to refer to coverage, carrier frequency quantity also is a key factor.When reaching the thresholding that need adjust outward like a certain network element carrier frequency number, cell cluster is excessive, and the carrier frequency number that it comprises is too much, is difficult to the carrier frequency that enough redundancies are admitted this cell cluster in the adjacent network element, and the meaning of cell cluster is difficult to realize in the resource adjustment; The sub-district is too small, and then its region covered is less than normal, the unusual fluctuations property increase of traffic, and the call-data analysis accuracy reduces.The exploitativeness of considering adjustment comprises 8-10 website usually, and about 150 carrier frequency, concrete quantity should be planned according to various network conditions.Carrier frequency disposes high and is that the base station that the traffic master covers can be separately as one bunch, and the base station carrier that for example covers certain campus is configured in about 100, and is the main coverage base station in this campus, and this base station can become one bunch separately so.
2) continuity
The geographic area that several base stations that cell cluster is meant and covers in the GSM network continuously, quality is relevant cover.Therefore continuity is extremely important in the process of dividing, and is divided in the cell cluster for call-data analysis or the resource adjustment all is nonsensical no matter cover discontinuous base station.
3) divide restriction
At first cell cluster should be that unit divides with the base station rather than be that unit divides with the sub-district.The division of cell cluster should not striden BSC (Base Station Controller base station controller); Be that base station in the same cell cluster should belong to same BSC. and also is appreciated that to being divided into two stages: can divide inspection adjustment border, lane place with the cell cluster of striding BSC earlier, treat that the border, lane place utilizes the cell cluster of not striding BSC to divide again after stable and carries out traffic forecast, Internet resources adjustment and other optimization work.
(2) the cell cluster partitioning algorithm is described
The cell cluster division methods is as shown in Figure 2, mainly comprises following a few step:
The first step: all minizones switching total degrees in the cell telephone traffic amount of statistics whole day, the BSC (specific to switching to which neighbor cell, like G010011-G010021, switch total degree and are meant incision and cut out the number of times sum.Should note whether not opening the sub-district, have influence on statistics).
Second step: with the base station is unit, calculates between each base station and switches total degree.
The 3rd step: get each the highest sub-district of BSC internal traffic; The base station is the center base station of automatic No. 1 cell cluster that generates under this sub-district; Title is decided to be XXBSC-S1; Add then with XXBSC-S1 and switch maximum base stations, adding and XXBSC-S1 switch more than second base station ..., until the scale of this cell cluster reaches the interpolation that just stops this cell cluster about 150 carrier frequency.
The 4th step: get base station under the highest sub-district of telephone traffic in the remaining sub-district again as No. 2 bunches center base station, algorithm is with No. 1 bunch of member who equally increases bunch.It should be noted that to other bunch member's sub-district and no longer add new bunch.The rest may be inferred calculates No. 3, No. 4 ... Deng bunch.The little base station of correlation can be put in OTHER bunch.
With the cell cluster is radio network optimization flow process and the means that unit carries out.
Cell cluster be cover continuously, intersection that traffic, several base stations (sub-district) that quality is relevant are formed; Has certain scale; The base station that telephone traffic is the highest is a core, base station, divides according to factors such as switching times, base station geographic position, carrier frequency quantity, and can carry out manual setting.Desire of the present invention protection point is on the basic methods of dividing based on cell cluster, formed new be the wireless network network optimization and the performance method for early warning and the flow process of unit with the cell cluster.Utilize cell cluster to be optimized adjustment for unit, not only more science carry out wireless optimization, economize on resources, improve optimization efficiency, also can reduce optimization personnel workload.
The network optimization flow process that is divided into the basis with cell cluster is following:
(1) the cell cluster network optimization system is gathered resource data and webmaster statistics automatically, according to the cell cluster partitioning algorithm a bunch division is carried out in sub-district in netting.
(2) on the basis that cell cluster is divided, network optimization personnel wherein should comprise resource utilization, border, lane place criterion of rationality, crucial wireless performance index etc. for cell cluster definition each item index thresholding.
(3) the cell cluster network optimization system according to each item thresholding of definition, is that unit carries out the index monitoring with the cell cluster, and reports unusually to network optimization personnel automatically.
(4) the cell cluster network optimization system mainly adopts following three kinds of processing modes for abnormal conditions:
The performance alarm module is regularly collected performance data from the estate performance data management module through interface.Contrast user-defined alarming threshold,, alarm is responded if property abnormality will be sent to the inner corresponding subprocess of handling unusually respectively.The processing subprocess is described below:
A. for bunch in certain sub-district traffic congestion appears, system adjusts the transmitting power of this sub-district automatically, and to bunch in the handoff parameter that switches of other sub-districts, comprise that the switching between cell selecting and reselecting parameters and the sub-district is setovered, to reach the purpose that traffic is shared.For example: congested duration was greater than 200 seconds in the CELL in cell cluster (A) 15 minutes; System reduces to 43dbm with the transmitting power of CELL (A) by 45dbm; The switching of other sub-district and CELL (A) biasing KOFFSETP is adjusted into 1 in bunch, and the congested duration of CELL (A) reduces to 0. after adjustment under normal conditions
B. for bunch in certain sub-district wireless performance index occurs and worsen, situation such as high call drop for example appear, frequency adjustment scheme in the system bunch is carried out scheme by the optimization personnel and is confirmed that system accomplishes adjustment automatically.
C. unreasonable situation occurs for the lane place boundary demarcation, system is that the basis provides irrational lane place border cell with the cell cluster, and the lane place border cell of suggestion.The optimization personnel carry out the adjustment of subdistrict position district according to scheme.Can not Automatic Optimal (can't accomplish automatically here; Because relate to base station cutover, can only generate scheme) for example: after a period of time is adjusted on the border, lane place, because variation has taken place for user's distribution and behavior; After a bunch division is calculated; Some bunch of having found the lane place boundary crossings, and can not comprise the sub-district of these bunches 90% or more, this means that this can the frequent location area updating of generations in these zones; Therefore need carry out the lane place adjustment to these regional base stations, reduce the location area updating number of times and arrived the purpose that reduces signaling traffic load.
As shown in Figure 4, see that from the cell cluster analysis chart QDBSC11 has more intactly comprised circular and two cell clusters of square hollow, but the cell cluster of solid squares is passed from the centre by the border, therefore sub-district in the cell cluster of solid squares is allocated to QGBSC15 fully.Reduce 17% through border adjustment QDBSC11 cross-location district, lane place switching times like this.
Cell cluster network optimization system data flow
Traffic and switch data statistical disposition (traffic and switch data administration module) are obtained the statistics of each sub-district of the whole network from the network statistical data storehouse, and this processing process gathers.Simultaneously result is imported cell cluster and divide processing procedure (bunch division module).
Cell cluster is divided processing procedure (bunch division module) and is obtained the basic resource data of each sub-district from resource database, comprising information such as latitude and longitude of base station.The result of calculation that this processing process combines traffic switch data statistical disposition (traffic and switch data administration module) to send here is simultaneously carried out the calculating that cell cluster is divided.Division information with result of calculation and cell cluster deposits the cell cluster thesaurus in then.
The performance data that (estate performance data management module) obtains from the webmaster staqtistical data base is handled in the estate performance data statistics, through aggregation process the result is imported the sub-district and goes out performance alarm processing procedure (performance alarm module).
