Strategy two: by carrying out corresponding power adjustable strategies to the community of heavy congestion, the coverage of community being optimized, realizing the resources balance of minizone.
For the situation of the small area jam that the number of users due to cell edge too much causes, when realizing the resources balance of minizone, usually strategy one can be adopted, by adjusting the switching reselecting parameters of community, the user of cell edge is made to switch to the adjacent area of community, thus the number of users in minimizing community, alleviate small area jam; And after have employed strategy one, when not alleviating small area jam significantly, strategy two can be adopted, by adjusting the power of community, reduce the coverage of community, thus reducing the number of users of community, the resource that this community is provided can meet the user in cell coverage area, alleviates small area jam.
The resources balance method of above-mentioned minizone, wherein, describedly adjustment is carried out to the handoff parameter between described congested cell and described target adjacent section and/or reselecting parameters be specially: the handoff parameter between described congested cell and described target adjacent section is adjusted, promote that the user in described congested cell switches to described target adjacent section, suppress the user in described target adjacent section to switch to described congested cell; And/or the reselecting parameters between described congested cell and described target adjacent section is adjusted, promote that the user in described congested cell is to the gravity treatment of described target adjacent section, suppress the user in described target adjacent section to the gravity treatment of described congested cell.
By to handoff parameter adjustment, congested cell difficulty incision is easily cut out and easily cuts difficulty with target adjacent section and cut out, realize the resources balance of minizone; Wherein, handoff parameter refers to: when the user in community switches to the adjacent area of this community, the parameter relevant to switching complexity; Such as parameter CIO (CellIndividualOffset, cell individual offsets), when this value of community be set on the occasion of time, the user in community is easier to be switched to adjacent area, that is: can accelerate user's switching to adjacent area from community; Otherwise, during for negative value, be delayed user's switching to adjacent area from community.
By to gravity treatment parameter adjustment, make the difficult gravity treatment in congested cell enter easy gravity treatment and go out the easy gravity treatment with target adjacent section and enter difficult gravity treatment and go out, realize the resources balance of minizone; Wherein, reselecting parameters refers to: when the user in community carries out gravity treatment to the adjacent area of this community, the parameter relevant to gravity treatment complexity; Such as parameter Qoffset (cell reselection offset), when this value of community is set to negative value, the user in community is easier to adjacent area gravity treatment, that is: can accelerate user's gravity treatment to adjacent area from community; Otherwise, on the occasion of time, be delayed user's gravity treatment to adjacent area from community.
The resources balance method of above-mentioned minizone, wherein, the described power to described congested cell and described target adjacent section carries out adjustment and is specially: adjust the power of described congested cell and described target adjacent section, reduce the coverage of described congested cell, expand the coverage of described target adjacent section, the user in described congested cell is switched or gravity treatment to described target adjacent section.
By Modulating Power size, the coverage reduction of congested cell and the coverage of target adjacent section are increased, number of users in the coverage of congested cell is reduced, and certain customers enter into the coverage of target adjacent section, realize the resources balance of minizone.
The resources balance method of minizone provided by the invention, by taking the reference factor such as switching times of number, code resource utilization and adjacent area to the number of users obtained in small area jam number of times, congestion ratio, community, BRU, and the index threshold values (as times of congestion threshold values, utilance threshold values) of load balancing need be carried out according to community, thus determine whether to need to carry out resources balance.When needs carry out resources balance, the switching Shi Gai community reported in conjunction with MR and the level difference of periphery adjacent area thereof, carry out prioritization to the periphery adjacent area of this community, determine target adjacent section, adopt above-mentioned adjustable strategies to adjust relevant parameter, realize resources balance, as shown in table 1 below:
Table 1
Wherein, in the handoff parameter of community and/or the adjustable strategies of gravity treatment, determine handoff parameter and/or gravity treatment adjustment size, then automatically generate the automatic real time down RNC of MML script and perform, thus the edge customer of this community is shared to target adjacent section.
For parameter CIO and Qoffset, determine the adjustment to parameter CIO and Qoffset by the relation of display in table 2:
Table 2
Wherein, cell-of-origin level when AdBm refers to switch, cell-of-origin level when BdBm refers to switch, (B-A) dB refers to level difference when adding up according to MR the switching obtained, and INT is bracket function; ROUNDUP refers to away from null value, is rounded up to numeral; Cell-of-origin to Target cell cio be switch time Target cell level deduct switching time cell-of-origin level the value that rounds of difference be multiplied by 2.When cell-of-origin occurs congested, switch or gravity treatment to Target cell, determine to switch reselecting parameters according to upper table.
Such as: an existing community 1, its adjacent area is community 2, the switch level according to the community 1 got and community 2: the level when community 1 is-96.02dbm, and time the level of community 2 is-86.5dbm, community 1 initiates to community 2 to switch; If community 1 there occurs congested, in order to reduce the number of users in community 1, more user in community 1 can be made can be switched in community 2, by adjustment handoff parameter, the switch level of community 2 is reduced, make more user can be switched in community 2, as shown in table 3, community 1 is set to 18 to the handoff parameter CIO of community 2, accordingly, community 2 is set to-18 to the handoff parameter CIO of community 1, utilizes the switching biased (CELLINDIVIDALOFFSET) of minizone, in handoff algorithms, realize the effect changing cell merge border.
Table 3
Execution script is as follows:
MODTNCELL:CELLID=" community 1 ", PLMNMCC=" 460 ", PLMNMNC=" 00 ", NRNCID=" XXX ", NCELLID=" community 2 ", CELLINDIVIDALOFFSET=18;
MODTNCELL:CELLID=" community 2 ", PLMNMCC=" 460 ", PLMNMNC=" 00 ", NRNCID=" XXX ", NCELLID=" community 1 ", CELLINDIVIDALOFFSET=-18;
Because cell switch determining thresholding is: (level value+Target cell, Target cell switches CIO/2 to Serving cell) > (Serving cell level value+preset hysteresis), what Target cell switched to Serving cell that CIO/2=Serving cell level deducts the difference of Target cell level rounds value; When the sluggishness of community 1 is constant, now, as long as meet: (level value+18/2 of community 2) >=-86dbm, that is: the level value of Target cell 2 can switch for during-95dbm, that is: switch Shi Dui community 2 level demand reduce, thus, make more user in community 1 can be switched in community 2, user in community 1 reduces, and alleviates the congestion situation of community 1;
In adjustable strategies to the reselecting parameters of community, by the reselecting parameters of adjustment community, the easy gravity treatment in community can be made to go out difficult gravity treatment and to enter.
Such as: the gravity treatment level according to the community 1 got and community 2: the level when community 1 is-96.02dbm, and time the level of community 2 is-86.5dbm, gravity treatment can be initiated to community 2 in community 1; If community 1 there occurs congested, in order to make in community 1 more user can gravity treatment in community 2, by the reselecting parameters of adjustment, the gravity treatment level of community 2 is reduced, make more user can gravity treatment in community 2, as shown in table 4, community 1 is set to-10 to the reselecting parameters Qoffset of community 2, accordingly, community 2 is set to 10 to the handoff parameter Qoffset of community 1, by the biased adjustment (QOFFSET1SN) of center cell and neighbor cell, to select in community and in reuse adoption process, the border of change cell reselection band.

Execution script is as follows:
MODTNCELL:CELLID=" community 1 ", PLMNMCC=" 460 ", PLMNMNC=" 00 ", NRNCID=" XXX ", NCELLID=" community 2 ", QOFFSET1SN=-10;
MODTNCELL:CELLID=" community 2 ", PLMNMCC=" 460 ", PLMNMNC=" 00 ", NRNCID=" XXX ", NCELLID=" community 1 ", QOFFSET1SN=10;
Because cell reselection decision threshold is: (level value-Target cell, Target cell is to Serving cell gravity treatment Qoffset) > (Serving cell level value+preset hysteresis), when the sluggishness of community 1 is constant, if the reselecting parameters Qoffset of community 1 is set to-10, now, as long as meet: (level value-(-10) of community 2) >=-86dbm, that is: can there is gravity treatment for during-96dbm in the level value of Target cell 2, that is: the level demand that gravity treatment Shi Dui community 2 occurs reduces, thus, to make in community 1 more user can gravity treatment in community 2,
To in the power adjustable strategies of community, by adjusting the power of community and periphery adjacent area thereof, realize carrying out equilibrium to the resource of minizone, as shown in Figure 4: there is a community A and periphery adjacent area community B and community C thereof, its small area A Severe blockage, needs the resources balance of carrying out minizone.
By the power reduction xdbm by community A, the scope that the coverage of community A is limited from solid line in figure becomes by the scope of dotted line limit, that is: the coverage of community A diminishes, decrease the number of users in the A coverage of community, alleviate the congestion situation of community A, but, if the power of Zhi Dui community A adjusts, and its adjacent area is not adjusted, possibly because the coverage of community A diminishes and causes weak covering, in order to avoid the generation of weak covering, the power of the adjacent area of community A can be adjusted, the power of community B is increased x1dbm, the power of community C increases x2dbm, the coverage of community B and community C is made to become large, avoid causing weak covering.By being reduced by high load capacity cell power, periphery adjacent area power increases, and changes coverage radius of cell, user is rationally shared.
Execution script is as follows:
MODTPCCPCH:CELLID=community A, PCCPCHPOWER=Y-x;
MODTPCCPCH:CELLID=community B, PCCPCHPOWER=Y+x1;
MODTPCCPCH:CELLID=community C, PCCPCHPOWER=Y+x2;
