Description
Technical field
The present invention relates to the mobile communication technology field, be specifically related to a kind of method and device of new adjacent area of definite Serving cell.
Background technology
As user terminal (UE, User Equipment) takies when certain Serving cell conversation, UE can measure some Broadcast Control Channel (BCCH according to the network definition, Broadcast Control Channel) intensity of frequency or dominant pilot, determine whether need changing a better service residential quarter, the switching of Here it is adjacent area.At GSM, CDMA, CDMA2000, in the various standard of WCDMA, the TD-SCDMA system, during user mobility management when it come to, all be unable to do without the adjacent area.And in the various standard system, the definable adjacent area quantity of each residential quarter is limited, is subjected to the restriction of processing speed, disposal ability and the related specifications of UE.
Network topology change, client's changes in distribution and wireless environment variation all require these variations of in time following up of adjacent area structure.The adjacent area optimize to be exactly in order effectively to utilize limited adjacent area resource, guarantees that network is in that rational adjacent area arranges and the work carried out.It is the element task that is only second to the network coverage that the adjacent area is optimized, and only guaranteed basis is firm, healthy, and all parameter optimizations just can show effect.Change with networking, wireless environment variation, user behavior, neighboring BS relationship also should running check, adjustment.
Adjacent area optimization comprises that adding the adjacent area optimizes, and namely increases new adjacent area on basis, existing adjacent area.For certain residential quarter (being assumed to be the A residential quarter), for various reasons, may exist some need define and actual undefined adjacent area.For example, in the new base station of network opening (residential quarter), the residential quarter of newly opening may need to add in the adjacent area of A residential quarter.Again for example, owing to reasons such as human negligence have been missed some adjacent area that need define.The adjacent area that adds during the adjacent area is optimized is optimized exactly and will be augmented these residential quarters in its Neighboring Cell List, so that UE can normally switch to better cell in moving process, guarantees good speech quality, avoids call drop.
In the GSM mobile system, the foundation that the measurement report that UE uploads to the base station under connection mode or collect the base station can provide the adjacent area to optimize.Revise some special parameters at network side, can force UE to report the related data of all BCCH frequencies, add the adjacent area and optimize suggestion by handling the measurement report of these magnanimity, can generating.For example ought receive when more and signal is strong about the measurement report of certain BCCH, base station identity code (BSIC, Base transceiverStation Identity Code), represent that this BCCH, BSIC corresponding district should add as the adjacent area of Serving cell.Because UE only measures BCCH, BSIC, signal strength signal intensity, can not read cell ID (CI, Cell Identity), and the same BCCH of the whole network, not unique usually with the residential quarter of BSIC, therefore need to confirm which residential quarter this BCCH, BSIC belong to, in order to add correct adjacent area.The method of available technology adopting is to calculate the Target cell that adds the adjacent area suggestion according to antenna azimuth, latitude and longitude of base station, BCCH, Network Color Code and BCC.As shown in Figure 1, suppose that Serving cell A-1 receives a large amount of measurement reports of BCCH=21, BSIC=46, the adjacent area that does not have BCCH=21, BSIC=46 in the adjacent area of Serving cell A-1, learn that by searching the basic database of the whole network there are B-2 and C-3 in the residential quarter of BCCH=21, BSIC=46 this moment.So, judging according to longitude and latitude (distance that is used for calculation plot and Serving cell) and the azimuth (being used for judging that whether the azimuth, residential quarter is towards Serving cell master angle of coverage) of these two residential quarters which is correct residential quarter, should be added in the table of adjacent area.
Prior art is subjected to the influence of residential quarter longitude and latitude, bearing data in the basic database of base station usually when generation adds the adjacent area suggestion; because may there be mistake in the above-mentioned data in the basic database; therefore provide to add adjacent area suggestion precision not high, also need the optimization personnel to spend the plenty of time usually and energy adds their confirmation.For example, shown in Figure 2, the same BCCH of residential quarter B and C, same BSIC owing between A, the B large mass of water is arranged, almost do not have traffic to distribute, and two residential quarter distances of A, B are far away and do not have covering overlapping area, and therefore, it is the adjacent area that A should add C.But because the information errors in the basic database is recorded as the C ' among Fig. 2 with longitude and latitude, the azimuth mistake of C residential quarter, adds the suggestion that B is the adjacent area thereby can provide A, and missed the important adjacent area C on the road.
As can be seen, the implementation method that adds the adjacent area of prior art depends on the basic database of base station.Information in basic database exists when wrong, and it is can the enforcement rate lower that suggestion is optimized in the adjacent area that prior art provides, and can't reach the requirement of daily enforcement.

Embodiment
The invention provides a kind of method and device of new adjacent area of definite Serving cell, based on existing network adjacent area topological structure, improve the precision that adds the adjacent area suggestion.The invention will be further described by specific embodiment below with reference to accompanying drawing.
Shown in 3, the method for the new adjacent area of the described definite Serving cell of the embodiment of the invention may further comprise the steps:
Step 30, control Serving cell issue the BCCH tabulation that includes all BCCH frequencies to user terminal.
Here, can revise relevant parameter at network side, issue relevant control command by Serving cell to UE, to force UE all BCCH frequencies that comprise adjacent area BCCH frequency be measured.The BCCH tabulation that Serving cell will include all BCCH frequencies sends to all interior UE of Serving cell scope, and all the BCCH frequencies in the BCCH tabulation of control UE are all measured; After each UE receives the described BCCH tabulation that Serving cell issues, each BCCH frequency in the described BCCH tabulation is measured and to the Serving cell reporting measurement reports, included the signal strength signal intensity of BCCH frequency, BSIC and the residential quarter of the residential quarter that measures in the described measurement report; Serving cell is collected the measurement report of all terminal to report.Among the present invention, it is right that the BCCH frequency of residential quarter and BSIC are referred to as the frequency base station identity code, with the signal strength signal intensity of residential quarter as the right signal strength signal intensity of this frequency base station identity code.
Step 31, the measurement report of the user terminal to send up of collecting according to Serving cell, the frequency base station identity code centering that from described measurement report, comprises, select signal strength signal intensity greater than predetermined first thresholding, report frequency greater than predetermined second thresholding and right to unmatched first kind frequency base station identity code with the frequency base station identity code of the adjacent area of described Serving cell, the frequency base station identity code that includes the residential quarter that measures in the described measurement report to and signal strength signal intensity, described frequency base station identity code is to referring to BCCH frequency and the BSIC of residential quarter.
Here, the measurement report that present embodiment is collected according to Serving cell at network side, the frequency base station identity code that comprises from measurement report is right to selecting described first kind frequency base station identity code.In the present embodiment, with the signal strength signal intensity of the residential quarter in the measurement report, as the frequency base station identity code of this residential quarter to corresponding signal strength signal intensity.In the present embodiment, UE can only report signal strength signal intensity greater than the measurement report of the residential quarter of predetermined value, does not then report for the measurement report of signal strength signal intensity less than the residential quarter of this predetermined value.The predetermined value here should be less than or equal to described predetermined first thresholding.
Here, right for arbitrary frequency base station identity code, described report frequency can be this frequency base station identity code to the occurrence number in the measurement report that reports at all UE, or the ratio of the right occurrence number summation of all the frequency base station identity codes in the measurement report that reports to the occurrence number in the measurement report that reports at all UE, with all UE of this frequency base station identity code.
Step 32, each frequency base station identity code for described first kind frequency base station identity code centering is right, in the predetermined cell set, search and the coupling residential quarter of described each frequency base station identity code to being complementary, and according to the coupling residential quarter that finds, determine the new adjacent area that described Serving cell need increase; Wherein, the set of described predetermined cell comprises: all first residential quarters in the higher level zone of described Serving cell ownership and all residential quarters in the higher level zone that second residential quarter of switching belongs to took place with described first residential quarter.
Step 33 is added described new adjacent area at the Neighboring Cell List of described Serving cell, specifically comprises parameters such as increasing the BCCH of described new adjacent area frequency, BSIC and CI.
Usually can a plurality of cell configuration that the geographical position is contiguous become to belong to same Location Area Code (LAC in the system, Location Area Code), perhaps belong to same base station controller (Base StationController) administration, namely certain LAC overlay area or certain BSC compass of competency all include a plurality of residential quarters usually.Therefore, in the above-mentioned steps 32, described higher level zone can be the LAC overlay area, or the BSC compass of competency.
In the above-mentioned steps 32, the set of described predetermined cell comprises: all first residential quarters in the higher level zone of described Serving cell ownership and all residential quarters in the higher level zone that second residential quarter of switching belongs to took place with described first residential quarter.Here, second residential quarter of switching took place in described and described first residential quarter, referred to exist in nearest one period scheduled time certain terminal to switch to described second residential quarter from described first residential quarter.By this selection mode, present embodiment has been rejected actual adjacent area of switching has been taken place, and why these adjacent areas do not switch, and may therefore it need be foreclosed because system mismatches and puts or reason such as wireless environment variation causes.May have the replicated plot between all residential quarters in the higher level zone that second residential quarter that all first residential quarters in the higher level zone of described Serving cell ownership and described and described first residential quarter took place to switch belongs to, their common factor is got in described predetermined cell set.
In the above-mentioned steps 32, each frequency base station identity code of first kind frequency base station identity code centering is right, the frequency base station identity code of the residential quarter in gathering with described predetermined cell respectively is to being complementary, if on the coupling, then according to BCCH, BSIC and the CI information of the residential quarter on the coupling, in the adjacent area of Serving cell, increase new adjacent area.
The step 30 of above-described embodiment～33 can be carried out by network side.
Present embodiment utilizes the measurement report of UE and network to switch parameter such as statistics to add the adjacent area and operate.Above-mentioned parameter all comes from existing network, has reflected valuable information such as practical radio communication environment, user behavior and traffic distribution.And, the BCCH frequency resource of existing network, adjacent area topological structure all are the results who continues to optimize for a long time, usually all has certain reasonability, be that existing network is after handling through the normal network optimization, even can't avoid occurring in network-wide basis with the residential quarter of BCCH frequency with BSIC, can guarantee that also the distance between them is enough far away.Based on this, present embodiment is broken through conventional thought, takes full advantage of existing network information and adds the adjacent area operation, and its realization is simple, and can farthest improve the accuracy that adds adjacent area suggestion, reduced the optimization personnel screen with frequently, with the workload of BISC mistake suggestion.Present embodiment has overcome tradition and has added the implementation method computational process complexity of adjacent area, and is subjected to the shortcoming of the influence of the error message (as longitude and latitude, azimuth) in the basic database easily.
For helping to understand present embodiment, below describe with a concrete applicating example.
This application is that the BSC compass of competency describes with described higher level zone in for example, for as shown in Figure 4, a plurality of BSC compass of competency has been shown among Fig. 4 for LAC, and wherein each enclosed region is a BSC compass of competency, and one has A～K BSC compass of competency.Solid circles in the BSC A compass of competency is represented Serving cell, and the BSC compass of competency of this Serving cell ownership is BSC A compass of competency.The adjacent area of all residential quarters in all empty circles among Fig. 4 (comprising by dotted open circles circle and solid line empty circles) expression BSC A compass of competency, wherein, the solid line empty circles is illustrated in the adjacent area (being described second residential quarter) that successful switch took place in one period nearest scheduled time, and the by dotted open circles circle is illustrated in the adjacent area that in one period nearest scheduled time successful switch did not take place.The circle of band shade is then represented other residential quarter the adjacent area of all residential quarters in above-mentioned BSC A compass of competency.
As can be seen, described second residential quarter among Fig. 4 is distributed in BSC A, B, C, E, G, H, the I compass of competency, the higher level zone of described second residential quarter ownership is BSC A, B, C, E, G, H, I compass of competency, and the BSC compass of competency of Serving cell ownership is BSC A compass of competency, and therefore described predetermined cell set then is all residential quarters in BSC A, B, C, E, G, H, the I compass of competency.Though also include the adjacent area of residential quarter in the BSC A compass of competency in the BSC L compass of competency among Fig. 4 and the BSC F compass of competency, because successful switch (dashed circle) does not take place, therefore be left out.By the set of cells that obtains with upper type, just comprised more suitable scope of this Serving cell periphery, avoided simultaneously because the indivedual adjacent areas of wrong definition cause the excessive problem of collection area.Because when the definition of individual cells mistake in the BSC A during adjacent area far away, the actual successful switch number of times in this adjacent area will be 0, thereby can be by filtering.This set is as the investigation scope, as the screening conditions that add the adjacent area suggestion.Because far away with frequently distributing usually through the network planning or routine optimization work with the BSIC residential quarter in the existing network, therefore in this set, can mate unique residential quarter (according to BCCH, BSIC) usually, can determine potential adjacent area exactly.
More than be that example is illustrated with the BSC compass of competency, for the LAC overlay area, its principle is also identical, repeats no more.
In the above-mentioned steps 32, in described predetermined cell set, search and the coupling residential quarter of described each frequency base station identity code to being complementary, the quantity of the coupling residential quarter that obtains all is one usually, at this moment, the information that directly will mate the residential quarter joins in the Neighboring Cell List of Serving cell as the information such as BCCH frequency, BSIC and CI of mating the residential quarter.
In the above-mentioned steps 32, in described predetermined cell set, search and the coupling residential quarter of described each frequency base station identity code to being complementary, the quantity of the coupling residential quarter that obtains is during greater than 1, at this moment, calculate described Serving cell respectively to the adjacent area jumping figure of each coupling residential quarter, and the information of the coupling residential quarter that the adjacent area jumping figure is minimum joins in the Neighboring Cell List of described Serving cell, described adjacent area jumping figure is the fewest number of hops that arrives the coupling residential quarter from Serving cell, wherein, the distance that arrives the adjacent area of current area from current area is a jumping.
Above-mentioned jumping figure manner of comparison is on the basis of existing network adjacent area topological structure, determines by contrast shortest path step number which is correct residential quarter.Namely search described each frequency base station identity code in the adjacent area of Serving cell to corresponding residential quarter, do not find in the adjacent area of the adjacent area of then continuing Serving cell and search, by that analogy, up to finding.The fewest number of hops corresponding district is the residential quarter that add as the adjacent area.As shown in Figure 5, Serving cell A is 3 to jump to the fewest number of hops of coupling residential quarter B, and Serving cell A is 5 to jump to the fewest number of hops of coupling residential quarter C, and selection this moment will be mated in the Neighboring Cell List that residential quarter B joins Serving cell A.If the quantity of the coupling residential quarter that the adjacent area jumping figure that calculates is minimum is during again greater than 1, for example, Serving cell A all is 3 jumpings to the jumping figure of coupling residential quarter B, C, at this moment, can from the minimum coupling residential quarter of described adjacent area jumping figure, select the coupling residential quarter that switching times is maximum or signal strength signal intensity is maximum, and the information of the coupling residential quarter that will select joins in the Neighboring Cell List of described Serving cell.
Usually the coupling residential quarters that should be added as the adjacent area of the overwhelming majority should be found within " three jump ", therefore when practical application, can simplify when allowing program pass inquire the 3rd layer of adjacent area and stop, to reduce amount of calculation.Namely, at the described Serving cell of above-mentioned calculating in the process of adjacent area jumping figure of each coupling residential quarter, arrive the adjacent area jumping figure of arbitrary coupling residential quarter greater than predetermined value if judge Serving cell, then stop the calculation services residential quarter to the adjacent area jumping figure of this arbitrary coupling residential quarter, and refusal joins this arbitrary coupling residential quarter in the Neighboring Cell List of described Serving cell.Suppose to find a more than same BCCH three within jumping, with the residential quarter of BSIC, the possibility that this situation occurs is very low, normally because mistake appears in the network planning, reply part residential quarter changes frequently (BCCH frequency) or changes operation such as LAC.
From the above as can be seen, present embodiment is in the affirmation process that adds the adjacent area suggestion, information such as existing network adjacent area topological structure, UE actual measurement report and switching statistics have been taken all factors into consideration, all take into account thereby wireless environment, user behavior, traffic can be distributed, allow existing network user's agenda assist to carry out the examination of adjacent area.Present embodiment does not re-use the information in the basic databases such as longitude and latitude, azimuth, thereby has broken away from the falsehood that causes because of the mistake in the basic database, and the algorithm of present embodiment is realized simple relatively.
