Embodiment
The automatic optimization method of neighboring BS relationship of the present invention is mainly realized in the BSS side.It is optimized flow process and is mainly concerned with the Operation and Maintenance platform (OMC) of BSS side and the main frame of BSS.
BSS and MS carry out communication, the MS in the realization optimization flow process and the information interaction of main frame.OMC is a background management system, by OMC the BSS system is managed, as parameter etc. is set.Among the present invention, OMC is mainly used to the data of gathering are carried out statistical analysis and optimized assessment, realizes the process of distributing rationally of adjacent area.System parameters allocation list and the neighboring BS relationship of host computer using BSS is configured into the relevant control of row communication etc., the system parameters allocation list here is not meant a concrete table, be general reference and the relevant table of BSS system basic configuration, for example store table, the pilot tone of each longitude and latitude position, sector table corresponding etc. with sector ID, main frame is controlled the operation of whole BSS by these system parameters allocation lists.Among the present invention, main frame receives the adjacent area data acquisition conditions that OMC sends, and carries out data acquisition according to this adjacent area data acquisition conditions, and receives the neighboring BS relationship configuration after OMC optimizes, and upgrades the neighboring BS relationship configuration of BSS system.
The present invention adds up the probability that pilot tone occurred of the relevant adjacent area of each sector by gathering the Pilot Strength Measurement Message (PSMM) that MS sends in the BSS side, and according to probability and other factors that the adjacent area pilot tone occurs neighboring BS relationship is readjusted.Wherein, if reporting of periodic pilot intensity measuring message (PPSMM), then described PSMM are arranged also can be PPSMM,, below all be that example describes with PSMM because principle is identical.
Fig. 1 is the flow chart of neighboring BS relationship Automatic Optimal.Fig. 2 is the transregional mobile schematic diagram of MS in the conversation.Below MS in conversing with this doing transregional moving, the transregional example that switches to does not take place as yet, with reference to the flow chart shown in the accompanying drawing 1, the present invention is described in more detail.
Step 101-102:OMC preestablishes the adjacent area data acquisition conditions, and the adjacent area data acquisition conditions is uploaded to main frame.
The predefined adjacent area of the OMC of BSS data acquisition conditions comprises the content of pickup area scope, acquisition time scope and collection etc.The pickup area scope can be specified the pilot tone of all sectors in the BSS scope, also can be specified the pilot tone of certain sector.The acquisition time scope is then set as required, for example can set initial, finish time etc. of cycle, the collection of collection.The content of gathering comprises pilot frequency intensity, pilot tone time delay, pilot set etc.The Operation and Maintenance platform is uploaded to these adjacent area data acquisition conditions in the main frame of BSS.
Step 103-104:BSS receives the PSMM that MS reports, and main frame extracts corresponding information according to the adjacent area data acquisition conditions from PSMM.
As shown in Figure 2,1 when move sector 2, MS can carry out signal strength measurement to adjacent sectors to the MS in conversation from the sector, and sends PSMM to BSS.According to the regulation of agreement, the pilot frequency information that comprises among the PSMM that MS reports comprises pilot strength information, pilot tone time delay, pilot set etc.Main frame obtains information such as pilot frequency intensity, pilot tone time delay, pilot set according to the adjacent area data acquisition conditions from PSMM.
Wherein, pilot set comprises movable pilot set (Active) and non-movable pilot set.In the cdma network, different sectors is distinguished with the PN sign indicating number.Wherein, movable pilot set is made up of the pilot tone of supporting at present the sector that MS calls out, the pilot tone of the PN=10 that is provided as sector among Fig. 21; Non-movable pilot set is by not forming for this MS provides the pilot tone of the sector of calling at present, the pilot tone of other sectors outside the sector that calling is provided at this MS place normally, comprise the pilot tone in candidate's pilot set (Candidate), adjacent area pilot set (Neighbor), the residue pilot set, the pilot tone of the PN=20 that provides as sector among Fig. 22, the PN=30 that sector 3 provides.
Step 105-106: main frame is according to the sector ID of sector under each pilot tone in the relevant system parameters allocation list inquiry pilot set of BSS.Wherein, the corresponding relation of pilot tone and sector ID configures in the system parameters allocation list when the network planning.
Owing to from the pilot set that PSMM gathers,, then inquire about, obtain the sector ID of pilot tone correspondence according to the system parameters allocation list for the pilot tone that in neighborhood region correlation chart, has disposed.Corresponding diagram 2, it is as follows to establish the result who searches: PN be 10,20,30 pilot tone respectively the ID of corresponding each sector be 1,2,3.The pilot tone that collects for PSMM, when main frame is retrieved in neighborhood region correlation chart, may find to contain the pilot tone that in neighborhood region correlation chart, does not dispose, represent that then this sector is undefined adjacent area, promptly in neighboring BS relationship, be not configured, if it is multiplexing that pilot tone does not have between each sector that BSS covers, direct inquiry system parameter configuration table then obtains the sector ID of pilot tone correspondence; If it is multiplexing that pilot tone exists between each sector that BSS covers, then calculate according to the latitude and longitude of base station information that provides in the system parameters allocation list, find nearest sector, obtain the sector ID of this pilot tone correspondence.And identify for undefined adjacent area, as a sign bit-identify is set this undefined adjacent area, be used for flow process afterwards, can in allocation list accordingly, carry out the operation of " increase " according to this sign position to this sector.
Then, main frame comprises that with the information of gathering the information after the analysis sends to OMC, and wherein this information comprises the sector ID of pilot frequency intensity, pilot tone time delay, pilot set and each pilot tone correspondence.
Step 107:OMC collects the information that main frame passes over, and is optimized analysis according to collected information, and generates new neighboring BS relationship configuration file.
At first OMC receives the information that main frame is gathered, and the data of being correlated with are deposited in the self database successively, mainly comprises pilot frequency intensity, pilot tone time delay, pilot set etc.
OMC carries out the adjacent area according to the information of gathering and optimizes analysis.At first in database, retrieve, set up a new data set, be the benchmark object with each pilot tone in the movable pilot set respectively, search the pilot tone that is occurred in each corresponding constantly non-movable pilot set that this benchmark object gathered, and corresponding relevant information such as pilot frequency intensity, pilot tone time delay.Specifically illustrate as follows: activity Pilot PN=10 with movable pilot set are benchmark, promptly being chosen to be this MS provides the sector of activity pilot tone to make benchmark, inquire about then in this period, all pilot tones in the corresponding non-movable pilot set of this pilot tone, the different same pilot tones that occur are constantly stored respectively.For example the pilot tone in the non-movable pilot set of PN=10 correspondence comprises: the pilot tone that the non-activity pilot tone in the moment 1 is PN=20; Constantly 2 non-activity pilot tone is PN=20,30 pilot tone; The pilot tone that the non-activity pilot tone in the moment 3 is PN=20.
For the convenience of calculating, can set in advance the analysis thresholding according to network signal situation and station layout, as pilot frequency intensity thresholding A, pilot tone time delay thresholding B, when making up above-mentioned data set, do not write pilot frequency intensity and be lower than A, or the pilot tone time delay is greater than the pilot frequency information of B.Certainly, above-mentioned threshold parameter also can be used as threshold level, sets at OMC in advance and sends main frame to, and main frame during image data, is just ignored the pilot frequency information that does not satisfy described threshold level requirement from PSMM.
Then, according to this data set, carry out neighboring BS relationship respectively at each benchmark object and optimize analytical calculation.Pilot tone with PN=10 among Fig. 2 is that example describes.At first add up the number of times that the pilot tone of each non-movable pilot set of data centralization that this benchmark object generates occurs.Wherein, delay time when considering pilot frequency intensity, pilot tone, reference pilot intensity and pilot tone time delay are computed weighted, can adopt following algorithm: number of times=∑ that the pilot tone of certain PN occurs according to actual conditions
n(the N time pilot frequency intensity weights of 1++the N time pilot tone time delay weights).If do not consider the influence of pilot frequency intensity, pilot tone time delay in this example, then the number of times of each non-activity pilot tone appearance is: the pilot tone of PN=20 occurs 3 times, and the pilot tone of PN=30 occurs 1 time.Calculate each non-activity pilot tone proportion then, can adopt following algorithm: the total degree that each non-movable pilot set pilot tone occurrence number/all non-movable pilot set pilot tones occur, method can get successively: the pilot tone proportion of PN=20 is 3/ (1+3)=75%, and the pilot tone proportion of PN=30 is 1/ (1+3)=25%.
If in the process of information gathering, there is the MS2 in another conversation also 1 to move to sub-district 2 from the sub-district, and the number of times that the adjacent area pilot tone that collects occurs is that the pilot tone of PN=20 occurs 1 time, because the present invention does not go to be concerned about and discerns is the information which MS is collected, it is Information Monitoring from all PSMM that receive, therefore the data that this MS2 is analyzed also add the aforementioned calculation process, then each non-activity pilot tone proportion is: the pilot tone proportion of PN=20 is 4/ (1+4)=80%, and the pilot tone proportion of PN=30 is 1/ (1+4)=20%.
At last, sort according to the priority of each non-activity pilot tone proportion size to each sector of adjacent area, generate the neighboring BS relationship configuration file then, wherein, the big ordering of pilot tone proportion is preceding, and corresponding sector priority is preceding.Be PN=20, PN=30 as this routine non-activity pilot tone ordering; Corresponding adjacent area sorts by priority the result and is: sector ID=2, sector ID=3; The desired neighboring BS relationship configuration file of generation system then.
More than describe with a MS, when online all PSMM are gathered, for the benchmark object in each active set, all calculate its non-activity pilot tone proportion respectively according to above method, finally correspond to the priority of adjacent domain relation, generate neighboring BS relationship configuration at each benchmark object.
Wherein, the related data information of the collection that the user can be preserved by the OMC Query Database, and check to optimize and analyze the adjacent area ranking results that the back generates.
Step 108-110: upgrade BSS and go up the neighboring BS relationship configuration.
OMC will optimize the neighboring BS relationship configuration file of analyzing generation and send the BSS main frame to, and BSS disposes according to the neighboring BS relationship that this document upgrades on the BSS.Thereby new neighboring BS relationship will be enabled by system, realize adopting new priority of adjacent domain order, realize increasing new available adjacent area or deleting unnecessary adjacent area, and this neighboring BS relationship is sent to MS.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
