Embodiment
Below in conjunction with accompanying drawing, a kind of packet control unit PCU collocation method and device that the embodiment of the invention is provided carry out explanation at length.
The packet control unit PCU collocation method that the embodiment of the invention provides; Before being actual being configured of each PCU (belonging to a base station controller together); Can carry out following two steps (can certainly carry out side by side with the process of configuration, the embodiment of the invention is not done qualification to this) in advance, the implementation of following two steps is separate; Below be merely differentiation, two steps have been numbered.
Step 1, obtain each sub-district channel load relevant of BSC management with PCU.
Specifically can extract the channel configuration situation of each sub-district,, calculate each sub-district channel relevant with PCU according to the channel configuration situation of each sub-district through the network operation maintenance centre, like the GPRS channel, the channel load that Abis channel and wireless channel etc. produce.Concrete computational methods belong to the scope of prior art, no longer carefully state at this.
The embodiment of the invention is only with each sub-district with some BSC management, and each PCU that distributes to this BSC configuration is that example describes, and in following narration, the sub-district all refers to each sub-district of same BSC management, and PCU also refers to each PCU of this BSC configuration.
Step 2, calculate each sub-district and other each minizone network coverage parameter weighted values.
In embodiments of the present invention; Network coverage parameter can be one of distance, minizone antenna directional angle angle and minizone switching times of minizone; The perhaps combination in any of above-mentioned parameter; Therefore, that network coverage parameter weighted value also just corresponds to one of following weighted value or following weighted value combination in any and value;
1, characterizes sub-district and other each minizones distance weighting value apart from distance.
2, characterize the deflection weighted value of sub-district and other each minizone antenna directional angle corner dimensions.
3, characterize what switching weighted value of sub-district and other each minizone switching times.
In embodiments of the present invention; Preferably; Need take all factors into consideration the network coverage parameter of distance, deflection angle (possibility of overlapping covering) and these three aspects of switching times of minizone; To improve the accuracy of PCU configuration, manage to same PCU close together, the deflection angle is less and switching times is more cell allocation as far as possible, reduce the exchange of the data between the different PCU as far as possible.In this case, the network coverage parameter weighted value in the embodiment of the invention refer to distance weighting value, deflection weighted value and switch weighted value and value.
Specify the step that computing network covers the parameter weighted value below.
The first step according to the distance relation of sub-district and other each minizone distances, generates the distance weighting value of other each sub-districts and this minizone respectively.Promptly through obtaining the latitude and longitude information of each sub-district; Confirm the distance of minizone, and be benchmark, calculate the distance of other sub-districts and this sub-district with each sub-district; According to other sub-districts that calculate and the distance of this sub-district distance, generate the distance weighting value of each sub-district and other minizones then.
Following table 1 is the example explanation with table 2.
Following table 1 is a minizone distance collation table.Can clearly be seen that from following table 1 distance of some sub-districts and other minizones is represented in each provisional capital, is example with sub-district A1, and the distance between sub-district A1 and sub-district A2 is 0 (sub-district that belongs to same base station); Distance between sub-district A1 and sub-district B1 is 1 kilometer, with the distance of C1 minizone be 2 kilometers, with the distance of D1 minizone be 3 kilometers or the like.
Table 1
With the distance of each sub-district and other each minizones according to from closely arranging (corresponding sequence number from small to large) to ascending order far away; According to the sequence number N (N is the natural number more than or equal to 1) that arranges; According to following create-rule, generate each sub-district and other each minizone distance weighting values.
Q1＝2
N-1(N≤16)；
Q1＝65536(N＞16)。
In the following formula, Q1 is each sub-district and certain minizone distance weighting value.
For example, be benchmark with the sub-district A1 in the table 1, because nearest (distance is 0) between sub-district A2, sub-district A3 and sub-district A1, therefore, during ordering, N=1, the distance weighting value between sub-district A2, sub-district A3 and sub-district A1 is 1;
Next is sub-district B1, B2 and B3, and therefore, during ordering, the N value of these three sub-districts equals 2, and the distance weighting value between sub-district B1, sub-district B2 and sub-district B3 and sub-district A1 is 2;
And the like, the distance weighting value between sub-district C1, sub-district C2 and sub-district C3 and sub-district A1 is 4; The distance weighting value of generation and sub-district A1 and other each minizones specifically sees the following form 2, and table 2 is tables of comparisons of minizone distance weighting value.
Table 2
In second step,, generate the deflection weighted value of each sub-district and other each minizones respectively according to the magnitude relationship of each sub-district and other each minizone antenna directional angle angles.According to the minizone switch data that from mobile radio communication, gets access to; Between the sub-district that does not switch; Think that there is not overlapping covering in these two sub-districts, not having the deflection weight setting between overlapping cell covered is a fixed maximum values (for example unification is set to 32 in the embodiment of the invention); For existing between the sub-district of switching; Through information such as each minizone antenna directional angle, base station relative positions, confirm the size of each antenna in cell deflection angle, similar with the minizone distance weighting; With some sub-districts is benchmark; According to the size ordering of this sub-district and other each antenna in cell deflection angles, confirm each sub-district deflection weighted value, generate the deflection weights of each sub-district and other minizones successively.
Each minizone antenna directional angle angle confirms that method is following: with S base station and T base station is example; Certain t1 corresponding antenna sector directions angle, sub-district is assumed to be Ta under the T base station; Certain s1 corresponding antenna sector directions angle, sub-district is Sa under the S base station, Ta, and the span of Sa is [180 °; 180 °], two sub-district deflection weights are established rules then following really:
For example with sub-district s1 benchmark, if other sub-districts for example the relative position relation of T base station and the S base station at sub-district s1 place at sub-district t1 place be the east side of base station T S in the base station, so between sub-district t1 and sub-district s1 the deflection weights regular as follows:
If Ta-Sa=180 ° of minizone antenna directional angle angle, the deflection weights between sub-district t1 and sub-district s1 are minimum value 1;
If Ta-Sa=-180 ° of minizone antenna directional angle angle, the deflection weights between sub-district t1 and sub-district s1 are maximum 32;
If minizone antenna directional angle angle | Ta-Sa|＜180 °; In this scope; The order that all minizone deflection weights are arranged according to minizone antenna directional angle angle is from small to large confirmed; Just the minizone antenna directional angle is more little, corresponding deflection weights more little (each sub-district increases by 1 successively by said sequence deflection weights, until reaching maximum 32).
If minizone antenna directional angle angle | Ta-Sa|＞180 °; In this scope; All minizone deflection weights deduct the order that 180 ° value arranges from small to large according to minizone antenna directional angle angle and confirm; Just the minizone antenna directional angle is more little, corresponding deflection weights more little (each sub-district increases by 1 successively by said sequence deflection weights, until reaching maximum 32).
If other sub-districts for example relative position relation of T base station and the S base station at sub-district s1 place at sub-district t1 place are the west sides of base station T S in the base station, so between sub-district t1 and sub-district s1 the deflection weights regular as follows:
If Ta-Sa=180 ° of minizone antenna directional angle angle, the deflection weights between sub-district t1 and sub-district s1 are maximum 32.
If Ta-Sa=-180 ° of minizone antenna directional angle angle, the deflection weights between sub-district t1 and sub-district s1 are minimum value 1.
Minizone antenna directional angle angle | the situation and the minizone antenna directional angle angle of Ta-Sa|＜180 ° | set pattern is then identical under the situation in the east side of base station S with base station T really under the situation of Ta-Sa|＞180 °, repeats no more at this.
In the 3rd step,, generate the switching weighted value of other each sub-districts and this minizone respectively according to what relation of sub-district and other each minizone switching times.Similar with minizone distance weighting value; According to the data that from mobile communications network, get access to each minizone switching times; Between the sub-district that has handoff relation, according to switching times from many to few sequence arrangement (corresponding sequence number from small to large), again according to the value of the sequence number M (M is the natural number more than or equal to 1) that arranges; Confirm the size of minizone switching weighted value, confirm rule as follows:
Q2=2M, the maximum of Q2 is 4096;
Q2 is the switching weighted value of each sub-district and some minizones.
When not having handoff relation between certain two sub-district, the switching weighted value of these two minizones is set to maximum 4096.
Three steps of aforementioned calculation minizone network coverage parameter weighted value are separate, do not have the branch of strict time order and function, and each number of steps has been merely to show differentiation.
The 4th step, the distance weighting value with the minizone that generates, deflection weighted value and switching weighted value add up, and promptly obtain each minizone network coverage parameter weighted value.
Below in conjunction with accompanying drawing 1, the idiographic flow of the PCU collocation method that the embodiment of the invention is provided carries out detailed explanation.
PCU collocation method as shown in Figure 1, that the embodiment of the invention provides comprises:
Step S101, judge whether BSC exists not the PCU that accomplishes configuration, if, execution in step S102, if not, execution in step S111.
Step S102, calculate the average channel load of the PCU (belonging to a BSC together) of the promising configuration of current institute, confirm the maximum channel load door limit value (maximum threshold of following summary current PCU permission) that PCU (hereinafter to be referred as current PCU) current to be disposed allows according to the average channel load that calculates.
The computational methods of average channel load are following:
All do not dispose the quantity of PCU the summation of the average channel load=channel load that current unappropriated all sub-districts are relevant with PCU/current;
Current unappropriated all sub-districts channel load relevant with PCU obtains through aforesaid step 1.
In the embodiment of the invention, preferably, can be with 110% to 115% the threshold value (upper limit) of the average channel load that calculates as the current PCU channel load.
Step S103, from current unallocated sub-district, choose an origin cell and distribute to current PCU;
Under the same BSC of concrete finger of current unallocated sub-district, the sub-district except sub-district of having distributed and the sub-district that in the current PCU assigning process, is dropped.
If the PCU that current PCU is first to be configured so, can select the origin cell of a sub-district as current PCU (PCU that first is configured) at the central area or the fringe region in the zone that BSC manages.
If current PCU is not first PCU that is configured, so, can be from unappropriated sub-district nearest sub-district of origin cell of accomplishing the PCU of configuration on the selected distance, as the origin cell of current PCU.
Whether step S104, the origin cell channel load relevant with PCU of judging current PCU have exceeded the maximum threshold that current PCU allows, if, turn to step S110, finish the configuration flow of current PCU.If not, carry out following step S105;
Step S105, according to other size order of network coverage parameter weighted value between each unallocated sub-district and this origin cell, select that minimum unallocated sub-district of weighted value;
Origin cell with current PCU is a benchmark, and the size of network coverage parameter weighted value can obtain through aforesaid step 2 between other each unallocated sub-districts and this origin cell.
Step S106, judge that this sub-district choose and all have distributed to the sub-district of the current PCU channel load sum relevant with PCU whether greater than the maximum threshold of current PCU permission, if, execution in step S107, if not, execution in step S108.
Step S107, in the current PCU layoutprocedure, abandon the sub-district of choosing among the step S105.Turn to execution in step S109 then.
The sub-district that in this step S107, abandons in the layoutprocedure of carrying out next PCU, will be alternative as unallocated sub-district again.
Step S108, give current PCU, carry out following step S109 then the cell allocation of choosing among the step S105.
Whether the number of times that the sub-district is chosen in step S109, judgement has reached preset threshold, if, execution in step S110; If not, turn to execution in step S105, i.e. network coverage parameter weighted value size sequence between each unallocated sub-district and said origin cell according to other is carried out the process of choosing of a unallocated sub-district.
In the collocation method of the PCU that the embodiment of the invention provides; Why utilize among the step S109 number of times of choosing the sub-district is carried out suitable restriction; Be because of an aspect, concerning same PCU, if constantly choose according to aforementioned order; Until all unallocated sub-districts of limit, might with this origin cell between the bigger sub-district of network coverage parameter weights (corresponding be far away, the deflection angle is big and the less sub-district of switching times) apart from origin cell distribute to this PCU; In addition on the one hand, constantly carry out the step of choosing and judging, computing time and cycle lengthening that can whole flow process, have reduced the efficient that PCU disposes.This step S109 is just for fear of above-mentioned 2 and be provided with.
The flow process of step S110, the configuration of end current PCU.Turn to execution in step S101 then, carry out the configuration of next PCU.
Step S111, judge whether to exist unappropriated sub-district, if this unappropriated cell allocation is given the PCU of last configuration; If not, process ends.
In the PCU collocation method that the embodiment of the invention provides, after all PCU are disposed completion, and after all sub-districts have all assigned, can also carry out the further optimizing process of each PCU configuration according to following method.
Add up the network coverage parameter weighted value between other each sub-districts and origin cell among all PCU and value; Suing for peace once more of the network coverage parameter weighted value that all PCU are corresponding with value; Divided by the quantity of PCU, obtain the corresponding network coverage parameter weighted value of each PCU and the mean value of value again.
If the network coverage parameter weighted value that some PCU is corresponding and value; Greater than this and the mean value of value that obtain; Can be under the prerequisite of the channel load maximum threshold that does not exceed the PCU permission; The origin cell of this PCU adjusted among the less PCU of network coverage parameter weighted value between other and this origin cell go, make the less sub-district of minizone network coverage parameter weighted value distribute to same PCU as far as possible and manage.
According to the packet control unit collocation method that the embodiment of the invention provides, the embodiment of the invention also provides a kind of packet control unit inking device, and is as shown in Figure 2, comprising: choose unit 201, judging unit 202 and allocation units 203; Wherein:
