Embodiment
In order to improve the operating efficiency of mobile communication system network topology planning, promote the quality of programme, in the embodiment of the invention, the network topology device for planning obtains the relational matrix of each network topology unit in the appointed area earlier; Obtain according to the default all-network topology planning mode that number is cut apart described appointed area of cutting apart according to described relational matrix again; Then, according at least one default network is pre-conditioned described all-network topology planning mode is screened, determine at least one objective network topology planning mode, last, carry out described objective network topology planning mode mobile communication system is carried out network topology planning.
In said method, according to actual application environment, the network topology unit can be base station, BSC, MSC, or among the LAC any one.And that the relational matrix of each network topology unit also has is multiple, for example: switching matrix, interference matrix, mobility model matrix or the like.Wherein, switching matrix can be according to obtaining in the daily network statistical data, and interference matrix can obtain according to the measurement report of each user terminal to send up, and the mobility model matrix can obtain by the mobility model algorithm, does not repeat them here.
Be that the base station is example and in conjunction with the accompanying drawings the preferred embodiment of the present invention is elaborated with the network topology unit below.
Consult shown in Figure 2ly, in the present embodiment, the network topology device for planning comprises memory cell 200, first processing unit 201, second processing unit 202, screening unit 203 and performance element 204, wherein:
Certainly, as shown in Figure 2,, also can user interface section 205 be set in the network topology device for planning, be used to export the network topological diagram planning chart of generation if administrative staff think directly to observe by display the network topology planning chart of generation.
Based on above-mentioned network topology device for planning, consult shown in Fig. 3 A, in the present embodiment, the network topology device for planning according to appointment to cut apart the flow process that number carries out network topology planning to mobile communication system as follows:
Step 300: the network topology device for planning obtains the relational matrix of each base station in the appointed area.
In actual applications, above-mentioned appointed area can be whole mobile communication system, can be the part mobile communication system also, in the present embodiment, is that the compass of competency of a MSC is that example is introduced with the appointed area.
On the other hand, in the appointed area relational matrix of each network topology unit have multiple, for example: switching matrix, interference matrix, mobility model matrix or the like; In the present embodiment, be that example is introduced with the mobility model matrix.Consult shown in Fig. 3 B, the mobility model matrix can reflect the tightness degree between each base station in the appointed area, and for example, the degree of association between base station A2 and the base station B1 (being that the mobile subscriber passes rate) is 2 (unit is: person-time); Perhaps, consult shown in Fig. 3 C, the mobility model matrix can also adopt mode shown in Fig. 3 C to draw, wherein, each end points is represented a base station, the weight of this base station of numeric representation in the end points, weighted value can be but be not limited to network load parameters (KPI) such as telephone traffic, paging amount, circuit number, number of users, carrier frequency number, and the degree of association between two base stations is then represented in the mobility model matrix in the binding between end points and the end points.
Step 310: the network topology device for planning is according to the default number of cutting apart, and determines the total number of adoptable network topology planning mode (hereinafter referred to as partitioning scheme) when the appointed area cut apart.
In the present embodiment, suppose that the number of cutting apart of appointment is 2, be about to the appointed area and be divided into two zones that so, adoptable partitioning scheme one has:
Kind.
Step 320: the network topology device for planning is with the discontinuous partitioning scheme deletion in geographical position.
For example, partitioning scheme shown in 3D will not adopt, wherein, base station A1 and base station B2 belong to same cut zone (shown in Fig. 3 D empty part), and base station B1, base station B3, base station B4 and base station A2 belong to same cut zone (shown in Fig. 3 D bend part).
In actual applications, whether whether each cut zone can have a common boundary to determine on the geographical position continuously according to the coverage of each base station (as, Thiessen polygon).
Step 330: the network topology device for planning is with the unbalanced partitioning scheme deletion of target balance parameters.
In actual applications, certain KPI value that needs are controlled emphatically is set to the target balance parameters, and according to this target balance parameters each partitioning scheme that obtains is screened earlier; And in the present embodiment, will be that carrier frequency number (TRX) is that example is introduced with the target balance parameters.Consult shown in the table 1, suppose that the TRX number of each base station among Fig. 3 C is as follows:
Table 1
| The base station | A1 | A2 | B1 | B2 | B3 | B4 |
| The |
10 | 10 | 6 | 9 | 4 | 10 |
Therefore, the network topology device for planning need determine to adopt the TRX sum of each cut zone that is obtained behind each partitioning scheme, for example, partitioning scheme shown in Fig. 3 E will not adopt, wherein, base station A2 and B4 belong to same cut zone (shown in Fig. 3 E empty part), and base station A1, B1, B2 and B3 belong to same cut zone (shown in Fig. 3 E bend part).Consult shown in the table 1, if adopt the partitioning scheme shown in Fig. 3 E, the TRX sum of two cut zone after then dividing is respectively 29 and 20, obviously, the TRX sum is unbalanced (promptly surpasses and set threshold values), and this just causes network load parameters such as the telephone traffic height between each cut zone uneven easily, can cause network security problem when serious, therefore, need be with the unbalanced partitioning scheme deletion of TRX sum.In the present embodiment, the TRX sum whether can judge according to the acceptable degree of TRX sum after the grouping of setting in advance by equilibrium, and so-called TRX sum is balanced to be meant that promptly the TRX sum of each cut zone is no more than preset threshold.
Step 340: the network topology device for planning will not satisfy the partitioning scheme deletion of preset restriction condition.
In actual applications, after the based target balance parameters screens each partitioning scheme that obtains, if need further to promote the quality of programme, then can also be according to the preset restriction condition to screening once more through all partitioning schemes that obtain after the above-mentioned screening.Above-mentioned preset restriction condition comprises at least a KPI value that is different from the target balance parameters, and this KPI value can be including but not limited to telephone traffic, paging amount, circuit number, number of users, carrier frequency number etc.In the present embodiment, comprise telephone traffic and the several two kinds of KPI values of paging are that example is introduced with the preset restriction condition.Consult shown in the table 2, in the present embodiment, telephone traffic and paging number in each the base station linchpin scope shown in Fig. 3 C are as follows:
Table 2
| The base station | A1 | A2 | B1 | B2 | B3 | B4 |
| Telephone traffic | 39 | 41 | 25 | 35 | 17 | 42 |
| The paging number | 110 | 109 | 72 | 96 | 39 | 102 |
Contents in table based on record in the table 2 can obtain, the average of the telephone traffic in each base station compass of competency is 99.5Erl, the average of paging number is 264: correspondingly, the constraints that is provided with in the present embodiment is, the telephone traffic total amount of each cut zone after cutting apart should satisfy 80%～120% of telephone traffic average, and the paging number of each cut zone should satisfy 80%～120% of paging number average value; So, the network topology device for planning just can come each partitioning scheme that obtains is carried out corresponding choice according to above-mentioned constraints.
Certainly, in actual applications, the factor of considering when formulating constraints can also increase according to actual conditions/delete/revise, simultaneously, the constraints of formulating also should suitably change along with the change of applied environment, and foregoing only for for example, does not repeat them here.
Step 350: the definite target partitioning scheme that the appointed area is cut apart of network topology device for planning (being objective network topology planning mode).
In the present embodiment, if the target partitioning scheme that the network topology device for planning is determined after step 300-step 350 has two or more, then the network topology device for planning can perhaps obtain all network topology program resultses and select for administrative staff according to wherein any one carries out network topology planning to the appointed area.For example, consult shown in Fig. 3 F, in the present embodiment, the final partitioning scheme of selecting is: base station A1, base station B3 and base station B4 belong to same cut zone (shown in Fig. 3 F bend part), and base station A2, base station B1 and base station B2 belong to same cut zone (shown in Fig. 3 F empty part).
In the above-described embodiments, when determining the target partitioning scheme, the network topology device for planning can also be provided with the threshold value of the degree of association between the sub-district, so that each partitioning scheme that obtains after step 350 screening is screened once more, for example: in the present embodiment, the minimum value of the cell association number that the network topology device for planning obtains is 7, so, partitioning scheme shown in Fig. 3 F will not adopt, wherein, base station A1, base station B1 and base station B2 belong to same cut zone (shown in Fig. 3 G empty part), base station A2, base station B3 and base station B4 belong to same cut zone (shown in Fig. 3 F bend part), and the cell association number between two cut zone reaches 17, considerably beyond minimum value 7, therefore, should give deletion.
Certainly, " with the discontinuous partitioning scheme deletion in geographical position " and " degree of association between the cut zone being surpassed the partitioning scheme deletion of setting threshold " these two kinds of screening modes of putting down in writing in the foregoing description are the prioritization scheme of select target partitioning scheme, if there are not the problems referred to above in concrete applied environment, then also can only screen each partitioning scheme according to target balance parameters and preset restriction condition, can reach desirable technique effect equally, not repeat them here.
Pass through the foregoing description, the network topology device for planning is when carrying out network topology planning to mobile communications network, according to the relational matrix between each network topology unit in the appointed area, obtain according to the default all-network topology planning mode that number is cut apart described appointed area of cutting apart; And according at least one default network load parameter described all-network topology planning mode is screened, determine at least one objective network topology planning mode; And carry out described objective network topology planning mode network topology planning is carried out in described appointed area.Like this, just saved loaded down with trivial details that manual mode of operation or semi-hand mode of operation brought, improved operating efficiency to a great extent, simultaneously, because the experience level of determining to be no longer dependent on the planning personnel of objective network topology planning mode, but screen according to parameter setting accurately, therefore, promoted the quality of programme greatly.
On the other hand, in the present embodiment, the network topology device for planning is when working out a plan scheme, except the target balance parameters is set, constraints can also further be set comes the various network topologies planning mode that obtains is screened, like this, the network topology that the network topology device for planning just can be selected to be fit to reference to two or more network load parameter is simultaneously planned mode, promptly can utilize the amount of movement between each network topology unit, the overall balance carrier frequency, circuit (ET), network load parameters such as telephone traffic and paging number come each network topology planning mode is screened; Like this, carrying out network topology when planning with respect to planning personnel under the prior art, only can carry out equilibrium treatment and can't take into account the situation of other network load parameters simultaneously at a network load parameter, the technical scheme that present embodiment adopts have further promoted the quality of programme.
With the practical situations is example, as shown in table 3, and after adopting the operating process of step 300-step 350 to carry out website topology planning to an appointed area with high density mobile subscriber flow, the improvement situation of every indication in this appointed area is as follows:
Table 3
| The project English name | The project Chinese | Existing mode | Mode of the present invention | Change | Reduce |
| LU(Intra?VLR) | Position in the MSC is upgraded | 325125 | 226293 | 98832 | 30.30％ |
| Inter-BSC?HO | Cross over the switching of BSC | 277930 | 161459 | 116471 | 41.91％ |
| LAC Paging (equilibrium degree adopts standard deviation to weigh) | The paging amount of lane place | 10080 | 6743 | 3337 | 33.11％ |
| LAC User (equilibrium degree adopts standard deviation to weigh) | The number of users of lane place | 7451 | 4232 | 3219 | 40.20％ |
| BSC TRX (equilibrium degree adopts standard deviation to weigh) | The carrier frequency number of BSC | 39 | 13 | 26 | 66.70％ |
| BSC Traffic (equilibrium degree adopts standard deviation to weigh) | The telephone traffic of BSC | 103 | 25 | 78 | 75.70％ |
As shown in table 3, after the operating process of the employing embodiment of the invention, realized following technique effect:
MSC internal cause user moves and the position of triggering is upgraded the quantity of (LU) and reduced by 30.30%,
It is about 41.91% that the quantity of crossing over the switching (Inter-BSC HO) of BSC has reduced, and mobile communication system has improved about 50% at the equilibrium degree aspect paging number, carrier frequency number, the telephone traffic,
The paging amount of lane place (LAC Paging) descends significantly, and the paging amount is balanced more, and standard deviation 10080 drops to 6743 before the cutover, has descended 33.11%:
The number of users of lane place (LAC User) is balanced more, and standard deviation 7451 drops to 4232 before the cutover, has descended 40.20%;
The carrier frequency number of BSC (BSC TRX) is balanced more, and standard deviation 39 drops to 13 before the cutover, has descended 66.7%;
The telephone traffic of BSC (BSC Traffic) is balanced more, and standard deviation 103 drops to 25 before the cutover, descends 75.7%.
Based on above-mentioned for example, carry out network topology behind the new BSC again and be planned to and routine its technique effect described in detail in the appointed area, to insert.
Before inserting new BSC, the network topology structure of appointed area is shown in Fig. 4 A, wherein, wherein, the zone of each reference numbers is respectively the compass of competency of a BSC, BSC 73 and BSC 74 belong to same LAC, and BSC 72 and BSC 76 belong to same LAC, and BSC 71 and BSC 75 belong to same LAC.
After inserting two new BSC, the operating process of step 300-step 350 is carried out network topology planning again to this appointed area according to the present invention, shown in Fig. 4 B, has 8 BSC in the appointed area, per two BSC form a LAC, mark off 4 LAC zones altogether.
So, elder generation is from introducing the aspect that influences of Inter-BSC HO ratio below.
As shown in table 4, because the BSC number becomes 8 from 6, increase to 1.3 times, the BSC border significantly increases, and increases to before the cutover 1.805 times through the handoff relation of extracting each KPI data statistics Inter-BSC HO.If adopt prior art network topology planning is carried out in the appointed area, promptly carry out conventional manual partitioning scheme, because the amount of movement between the base station is not measured as reference, whether the selection of also just being unable to estimate the LAC border is reasonable, thereby can't consider whether can increase the cost of Inter-BSC HO.And after the operating process that adopts the embodiment of the invention to provide carries out network topology planning, basically identical before the ratio of Inter-BSC HO and the planning.Consult shown in Figure 5ly, compare, adopt the technical scheme (being intelligent cutover) of the embodiment of the invention clearly to make the absolute value of Inter-BSC HO ratio reduce 17.19% with existing manual cutover mode (being conventional cutover).The minimizing of Inter-BSC HO can be simplified the signaling process of switching greatly, reduces the signaling traffic load of BSC.
Table 4
| Project | Inter-BSC HO ratio |
| Before the planning | 0.22713518 |
| After using prior art to plan | 0.41009258 |
| After using technical solution of the present invention to plan | 0.23823705 |
On the other hand, because the number of the LAC in the indicating area becomes 4 from 3, therefore, the LAC border also significantly increases, with respect to manual partitioning scheme, the embodiment of the invention has just fully taken into account the LAC border in the influence of diverse location to the LU sum before cutting apart, therefore the LAC border has been arranged on the low zone of user mobility, reduced the number of Intra-VLR LU (position of VLR inside is upgraded),) (because do not change the MSC border, therefore Inter-VLR LU (position between the VLR is upgraded) no change almost), the reduction of LU has reduced the demand of user for the SDCCH channel greatly, has reduced the load of SDCCH channel, increased the capacity of SDCCH channel, thereby reduced the possibility that to connect, increased call completing rate, and then promoted user experience greatly.
Generally speaking, after the operating process that the employing embodiment of the invention provides, every network load parameter all obtains further equilibrium, and concrete variation is consulted shown in Figure 6.
Obviously, those skilled in the art can carry out various changes and modification to the embodiment among the present invention and not break away from the spirit and scope of the present invention.Like this, if these in the embodiment of the invention are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the embodiment among the present invention also is intended to comprise these changes and modification interior.
