Embodiment
The invention provides a kind of method of between attaching position register and core net, carrying out flow control, core of the present invention is: send the OVERFLOW message of the LEVEL parameter of carrying expression traffic handing capacity information between MSC and HLR, MSC and HLR carry out flow control according to this OVERFLOW message.
Describe the present invention in detail below in conjunction with accompanying drawing, the concrete handling process of the embodiment of the method for the invention comprises the steps: as shown in Figure 2
Step 2-1, OVERFLOW (flow overload) message is set in the MAP of mobile communication system (Mobile Application Part, MAP) agreement.
The present invention at first need be in each mobile communication system, such as, increase newly in the MAP of GSM/CDMA/WCDMA system an OVERFLOW message is set.The protocol stack schematic diagram of MAP as shown in Figure 3, above-mentioned OVERFLOW message can be arranged on the TC primitive of protocol stack of MAP.
