Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
For guaranteeing the enforcement of this method, need in base station controller (BSC), to be configured in advance parameter down, comprising: the congested control time interval of power, power congestion threshold, carrier frequency power output thresholding, base station down signal level thresholding and quality threshold, power adjustments granularity and congested control switch penalty cycle etc.The precedence information that in base station controller, also needs the congested control operation of allocating power, the promptly preferential operation of selecting the carrier frequency power output of the congested time slot of minimizing power, the still preferential operation of selecting the user on the congested time slot of power is switched to other time slot outside the time slot of current place.
Above-mentioned thresholding all is empirical values, can be according to the field condition adjustment.Below each threshold parameter is specifically described.
The congested control time interval of power: in order to prevent frequently to carry out the congested control operation of power, be set at interval the congested control time of power, if congested control operation is not then carried out less than the congested control time interval of this power in the interval of twice congested control.
The power congestion threshold: when each carrier frequency of base station at the gross output of identical time slot during greater than this thresholding, think that then that power has taken place is congested, this thresholding can be by the percentage value of base station design power, if get 100% of base station design power, promptly the power congestion threshold equals the design power of base station.
Carrier frequency power output thresholding: when power is congested, if select the operation of the carrier frequency power output of the congested time slot of minimizing power, power output to time slot is regulated, and has only when carrier frequency and during greater than this thresholding, just can reduce the operation of power output in the power output of this time slot.
Base station down signal level thresholding and quality threshold: when power is congested, if select the operation of the carrier frequency power output of the congested time slot of minimizing power, need then to judge that whether signal level that the user receives and quality are respectively greater than base station down signal level thresholding and quality, have only respectively greater than the time, think that just the signal quality of the current reception of user is good, can reduce the power output of carrier frequency at this time slot.
The power adjustments granularity: when power was congested, if select the operation of the carrier frequency power output of the congested time slot of minimizing power, the power adjustments granularity was stipulated the minimum step of each power adjustments.
The congested control handoff failure punishment cycle: when power is congested, if select the user on the congested time slot of power is switched to other time slot outside the time slot of current place, carry out in the sub-district or during the handoff failure of minizone certain user, this user is punished, in this cycle, can not select this user to carry out once more because the congested switching that causes of power.
Figure 1 shows that the control method that present embodiment power is congested, comprising:
101: when mobile phone away from or during near base station (BTS), power control is carried out in the base station, when power output changes, to BSC transmission power control Indication message;
Carry in the power control Indication message: the performance number of site identity, cell ID, carrier frequency sign, time slot mark and this time slot.BTS sends to BSC with each carrier frequency in the performance number of each time slot by power control Indication message.
102:BSC preserves the performance number of time slot, and calculates the gross output of each carrier frequency at identical time slot after receiving power control Indication message;
103:BSC is according to calculating the gross output of resulting each carrier frequency at identical time slot, judge whether to exist the time slot of gross output greater than the power congestion threshold, if exist, it is congested to think that then power has taken place this time slot, this time slot is called the congested time slot of power, execution in step 104; Otherwise, finish;
Whether the 104:BSC judging distance last time carried out the time interval of the congested control of power greater than the congested control time interval of power, if greater than, then carry out the congested control of power, execution in step 105; Otherwise, execution in step 104;
105:BSC selects the congested control operation of being carried out of power and carries out, and the congested control operation of power comprises: reduce the carrier frequency power output of the congested time slot of power and the user on the congested time slot of power is switched to other time slot outside the time slot of current place.

All users on the congested time slot of 201:BSC detection power, judge whether to exist the downlink signal levels that receives the base station and quality respectively greater than the base station down signal level thresholding and the quality threshold that are disposed, and the carrier frequency power output is greater than the user of the carrier frequency power output thresholding that is disposed, if exist, then execution in step 203; Otherwise, execution in step 202;
202: carry out the user on the congested time slot of power is switched to the congested control operation of power of other time slot outside the time slot of current place, finish;
203:BSC obtains the required carrier frequency power output that is adjusted to of this time slot according to the carrier frequency power output and the power adjustments granularity of user place time slot, generates the power adjustments instruction, carries the carrier frequency power output after the adjusting and the time slot of adjusting, sends to BTS;
For example, the carrier frequency power output of user place time slot is 6 watts, and the power adjustments granularity is 1 watt, and the carrier frequency power output after then regulating is 5 watts.
After 204:BTS receives the power adjustments instruction, adjust the carrier frequency power output of corresponding time slot.

301:BSC searches the user (congested time slot user) of one or more low priorities on the congested time slot of power, congested time slot user is assigned on gross output other time slot less than the power congestion threshold outside the time slot of place;
The user who selects low priority is in order to guarantee the call performance of high-priority users, to reduce high-priority users because switch probability of call takes place.
302:BSC judges whether the congested time slot user who finds is in congested control handoff failure in the punishment cycle, if be in, then execution in step 301; Otherwise, execution in step 303;
Whether other time slot that 303:BSC detects sub-district, congested time slot user place exists idle channel, if exist, then execution in step 304; Otherwise, execution in step 305;
304:BSC starts intra-cell and changes process, congested time slot user is switched on the time slot of idle channel execution in step 306;
305:BSC judges whether congested time slot user's adjacent area satisfies switching condition, if satisfy, then carries out the minizone and switches;
The sub-district switching condition is:
(1) signal level of adjacent area inserts level greater than the lowest signal of neighbor cell configuration;
(2) adjacent area has the time slot of gross output less than the power congestion threshold, and preventing to cut new user, that power takes place once more is congested.
306: if handoff failure then carries out congested control handoff failure punishment to congested time slot user, for this user starts timer, timing is the congested control handoff failure punishment cycle, forbids selecting this user as the user of switching in this cycle.
When base station controller carries out the congested control of power once more, if select the user is switched in other time slot or adjacent area in the sub-district, when the congested time slot user who selects to cut out, forbid selecting to be in the user of congested control handoff failure in the punishment cycle, guaranteeing selecting the user that can cut out, thereby reduce the gross output of this time slot to the congested time slot of power takes place.
