Step S100, control each base station to its coverage emissioning controling signal, feed back corresponding response signal when mobile terminal receives the control signal of base station immediately;
The first power that the response signal of the described mobile terminal that the first base station that step S200, detection connect with described mobile terminal receives is corresponding; Detect and whether each base station exists the 2nd base station, and the 2nd power corresponding to response signal of described mobile terminal feedback that the 2nd base station receives is greater than the first power; If existing, then judging whether the difference of the 2nd power and the first power is greater than threshold value, if described difference is greater than threshold value, then performing step S300;
Step S300, control mobile terminal are connected with the 2nd base station, firmly switch to realize the base station of mobile terminal in cellular mobile communication.
Below in conjunction with specific embodiment, above-mentioned steps is described in detail.
In the step s 100, control each base station to its coverage emissioning controling signal, feed back corresponding response signal when mobile terminal receives the control signal of base station immediately. The terminals such as mobile terminal can be mobile phone, panel computer. Cell range (being also the exactly geographical position range) emissioning controling signal that each base station covers to it, and each base station is controlled by mobile switching centre (MSC, MobileSwitchingCenter). Mobile switching centre controls each base station constantly to emissioning controling signal in its cell range covered, and feeds back corresponding response signal immediately when mobile terminal receives the control signal of each base station; When base station receives the response signal of mobile terminal, by Feedback of Power corresponding for described response signal to MSC.

If S204 exists, then judge whether the difference of the 2nd power and the first power is greater than threshold value, if described difference is greater than threshold value, then perform step S300; If described difference is not more than threshold value, then mobile switching centre controls described mobile terminal and is still connected with the first base station.
Specifically, described MSC receives the power of the response signal of the mobile terminal that ICCID and the IMEI code of each base station feedback is uniquely determined, when the first power of the response signal of the described mobile terminal received by the 2nd power of the response signal of the described mobile terminal received by MSC detects the 2nd base station is greater than the first base station that described mobile terminal connects, if the 2nd power is greater than threshold value with the difference of the first power, MSC controls mobile terminal and is connected with the 2nd base station, if the 2nd power is less than with the difference of the first power or equals threshold value, MSC controls mobile terminal and is still connected with the first base station.

Specifically, mobile switching centre's control mobile terminal is connected with the 2nd base station, and corresponding revise mobile switching centre stores by the connection relation of ICCID code and the determined mobile terminal of IMEI code and base station. It is called hard switching when mobile terminal is from a cell merge to another community, when the base station that is mobile terminal connects changes, it is called hard switching. When MSC control described mobile terminal be connected with described 2nd base station time, amendment MSC in store by the connection relation of ICCID code and the determined mobile terminal of IMEI code and base station, the ICCID code being revised as this mobile terminal associates with the 2nd base station with IMEI code.
Preferably, described 2nd power is that described mobile terminal receives maximum power value corresponding in each response signal that the control signal of each base station feeds back. That is, among the multiple base stations around mobile terminal, the performance number of the response signal that the 2nd base station is corresponding is maximum. The power that this base station receives the response signal of mobile terminal corresponding is the highest. Then, judge whether the difference of the power that maximum power is corresponding with the base station that mobile terminal connects exceedes threshold value, exceed and just firmly switch, the base station that mobile terminal and maximum power value associate is connected; Otherwise, constant. Like this, when making the boundary ground Tape movement of mobile terminal between two or more community, avoid and frequently firmly switch, thus promote the processing efficiency of MSC, also make the communication between mobile terminal and base station more stable.
