Below we will be example to base station controller and packet processing unit with the base station, such scheme is described in detail, as shown in Figure 3, comprise the steps:
Step 301, base station receive the message that each network entity sends, respectively statistical circuit territory load condition and packet domain load;
The specific implementation method of statistical circuit territory load condition described in this step and packet domain load condition, in step 202, done detailed description, here no longer repeat, in the present embodiment, the circuit domain load condition is the shared ratio that receives total message count of circuit domain message, and the packet domain load condition is the shared ratio that receives total message of packet domain message; Perhaps, the circuit domain load condition is a circuit domain message queue residue length, and the packet domain load condition is a packet domain message queue residue length; Perhaps, the circuit domain load condition is the circuit domain message queue length that the base station receives, the packet domain load condition is the packet domain message queue length that the base station receives, and the implication of circuit domain load condition and packet domain load condition representative does not influence enforcement of the present invention.Before this step, system at first is provided with corresponding circuit domain overload threshold and packet domain overload threshold according to above-mentioned load condition in the base station, so that the judgement of load condition is carried out in the base station.
Step 302, load judgment is carried out in the base station, is in overload according to circuit domain overload threshold decision circuitry territory business, then changes step 303;
Concrete determination methods, according in the step 301, the difference of load condition is divided into several situations:
