Detailed description of the invention
The basic thought of the present invention is: base station is when the current load in certain sector being detected beyond target load (bearing load of setting), the user terminal to cutting this sector is needed to send a load adjustment factor, make user terminal when the judgement being linked into this sector, the signal intensity judgement accessing this sector it is re-used as after measured signal intensity is deducted described load adjustment factor, so that the user terminal originally meeting access conditions no longer sends the message accessed to this sector, avoid causing what this sector caused because of over loading to make the situation that in this sector, the communication quality of user terminal all declines, thus improving the QoS of cdma system. additionally, owing to not only relying on the signal strength detection of subscriber terminal side when switching accesses, system side also can make access judgement according to the signal strength measurement of user terminal, therefore, after user terminal utilizes the access that the load adjustment factor of sector be made whether to access described sector to judge, preferably making this accessing and judge that signal strength values used reports to base station side, this application scenarios is primarily directed to different system cell and makes the scene of switching Access Control. the present invention realizes the access to overload sector well and protects, and improves the service quality of whole communication system.

Base station is when the load determining certain sector exceeds the target load set, for instance beyond the peak load of design, then determine load adjustment factor for this sector. Load adjustment factor in the present invention is a signal strength values, and unit can be power or the decibel dB of signal, specifies user terminal by which kind of mode is determined as signal strength measurement in viewing system. When the load of sector is without departing from the target load set, the load adjustment factor of described sector is 0. When beyond target load bigger time, bigger load adjustment factor is set, as arranged beyond the grade of target load difference, each difference grade corresponds to a different load adjustment factor. Can also pass through to be achieved in that: no matter beyond the amount of target load number, it is disposed as one and determines value (load adjustment factor is bigger), so that the user terminal not accessing described sector at present can not be linked into this sector again, namely once time-out goes out target load, the access of any user terminal will be refused in described sector. The determination of load adjustment factor can access the difference of the threshold signal strength of this sector or the arbitrary value more than this difference according to the signal intensity maximum reported in active user's terminal with permission user terminal. Namely the purpose that arranges of load adjustment factor is avoid this sector to access new user terminal again, even if the measure signal intensity of this user terminal has reached the threshold signal strength accessed.
Step 102: described load adjustment factor is notified described user terminal by base station.
