Pass through above-described embodiment, can find out: utilize method provided by the invention, when the Serving cell overburden, directly judge and find out the terminal that to switch, terminal is switched in the corresponding adjacent cell, that is, directly solve the extra-heavy problem of current area, alleviate the communication quality of the congested raising terminal of current network, improve network resource utilization.
Embodiment two
For present invention is described in more detail, the below is described in detail take embodiment two as example, specifically shown in the method flow diagram of Fig. 2, comprising:
Step 201: when detecting the current area overload, from the adjacent cell signal strength values that terminal is measured, select the maximum signal value;
Need to prove, so-called " signal strength values " can be Reference Signal Received Quality value RSRQ or Reference Signal Received Power value RSRP, also can be other parameter values that can reflect the signal strength signal intensity of residential quarter.
For example: terminal 1-20 selects respectively the signal strength values maximum of adjacent cell 1, terminal 20-40 selects respectively the signal strength values maximum of adjacent cell 2, it is big-and-middle that terminal 40-60 selects the signal strength values of adjacent cell 3, and terminal 60-80 selects respectively the signal strength values of adjacent cell 4 big-and-middle.
Step 202: judge successively described maximum signal value that terminal is measured and and the signal strength values of current area between difference whether in the difference threshold scope, step 203: if, then described terminal satisfies the load switching condition, step 204: otherwise described terminal does not satisfy the load switching condition; For example: judge successively the difference of adjacent cell RSRQ that terminal 1-10 measurement reports and current area RSRQ in the difference threshold scope, then terminal 1-10 satisfies the load switching condition, the like detect, terminal 30-40, terminal 40-50 satisfy the load switching condition.
Step 205: after judging that successively the terminal that will satisfy the load switching condition switches to the adjacent cell of signal strength values maximum, whether described adjacent cell load is greater than the adjacent cell load-threshold, step 206: if greater than, then current terminal can not switch in the described adjacent cell, step 207: otherwise current terminal can switch in the described adjacent cell;
Before judging, detect the load condition of adjacent cell, comprising:
If current area is positioned at identical base station with neighbor cell, then the load condition of the described neighbor cell of direct-detection;
If front residential quarter is positioned at different base stations with neighbor cell, then send the starting load status request message to neighbor cell, self load condition of reception of neighboring cell periodic report.
For example: judge whether terminal is switched rear corresponding adjacent cell load greater than the adjacent cell load-threshold, if after judging that the 1-6 terminal is switched, less than the adjacent cell load-threshold, show that then terminal 1-6 can switch to adjacent area 1, switch past tense if determine the 7th and 8 terminal, greater than load-threshold, show that then terminal 7 and 8 can not switch to adjacent cell 1, judge successively terminal 30-37 and can switch to adjacent cell 2, terminal 40-49 can switch to adjacent cell 3.
Step 208: each terminal that can switch to corresponding adjacent cell, choose switching terminal in the mode of choosing that quantity increases progressively one by one, the switching terminal of choosing is switched to after each self-corresponding adjacent cell, step 209: if the current area load is less than the current area load-threshold, then the terminal of choosing is switched in each self-corresponding adjacent cell, step 210: if be not less than, then continue to choose switching terminal, until when not having switching terminal to choose, adjust described difference threshold scope, and return step 202.
For example: each terminal that can switch to corresponding adjacent cell, choose switching terminal in the mode of choosing that quantity increases progressively one by one, can be to choose in the mode of choosing that increases progressively of fixed qty, as being that to be 42 second time be 6 for the third time for the first time with number 2 incremental manners, the also mode of choosing that fixedly do not increase progressively of quantity, as for the first time being that to be 31 second time be 4 for the third time, specifically do not limit the number of at every turn choosing, but must be that the mode that increases progressively is selected.The switching terminal of choosing is switched to after each self-corresponding adjacent cell, judge that the current area load is whether less than the load-threshold of current area.Such as, if when terminal 1-6 switched to adjacent cell 1, judge the load of the current area after the switching less than load-threshold, then directly 1-6 is switched to adjacent cell 1; If judge greater than load-threshold, then continue to choose switching terminal, if after judgement switched to adjacent cell 2 with terminal 30-37, the current area load was less than thresholding, then 1-6 is switched to adjacent cell 30-37 is switched to adjacent cell 2, switch adjacent cell 1 if judge successively terminal 1-6, terminal 30-37 switches to adjacent cell 2, and terminal 40-49 switches to after the adjacent cell 3, the current area load is still greater than thresholding, showing does not have selectable switching terminal, then adjusts described difference threshold, returns step 202.
Provide method in above-described embodiment, can be according to practical situations, concrete processes the terminal classification, judges the terminal that satisfies condition, and the load-threshold of current area and the load-threshold of adjacent cell also are to decide according to actual conditions.Do not do concrete restriction at this.
Further, to switch the problem that the pingpang handoff that may occur after the execution causes moving equilibrium load hand-off process inefficiency in order solving, to the present invention proposes a kind of solution, be specially:
Step 211: after adjusting each time described difference threshold, judge switching offset parameter after last the adjustment whether in adjustable extent, if, then the last time is switched offset parameter and increase a step-length, if do not exist, then do not adjust processing.
Then after carrying out the terminal switching, can carry out handoff parameter handles through consultation, specifically comprise: step 212: the handoff parameter that switching offset parameter that the change process adjusts the last time and current area is set by mobility parameters is notified the adjacent cell to correspondence, switches side-play amount so that adjacent cell is adjusted the residential quarter of self.
Perhaps after carrying out the terminal switching, also comprise: the difference of calculating the switching side-play amount of the last switching offset parameter of adjusting and current area, by mobility parameters the change process is set and notifies adjacent cell to correspondence with described difference, so that side-play amount is switched in the residential quarter that adjacent cell is adjusted self according to described difference.
Preferably, after adjacent cell is adjusted the residential quarter switching side-play amount of self, also comprise:
Step 213: whether self residential quarter side-play amount was in the switching side-play amount modification scope that allows after adjacent cell judge to be adjusted, if, then send successful instruction to current area, if not, the switching side-play amount that then sends failure command and carry described permission is revised scope to current area.
Certainly, in order better to avoid pingpang handoff, the present invention also just carried out the minizone parameter negotiation to process before carrying out switching.
By above-described embodiment two, can find out, method provided by the invention not only can directly be judged and finds out the terminal that can switch, terminal is switched in the corresponding adjacent cell, namely, directly solve the extra-heavy problem of current area, alleviate the communication quality of the congested raising terminal of current network, improve network resource utilization; All right, handle the ping-pong that can exist after better avoiding switching through consultation by handoff parameter.
