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.

By itself traffic handing capacity information of this message informing the other side, the other side carries out corresponding flow control according to this message between the MSC of HLR and core net.

Carry out flow control by sending OVERFLOW message between step 2-2, MSC and the HLR.

When the traffic handing capacity of the MSC of HLR and core net and message traffic all just often, the MSC of HLR and core net all normally carries out Business Processing.Do not send OVERFLOW message mutually.

When the MSC of HLR or core net either party's overall traffic handing capacity or drop to the numerical value of a setting at some office direction traffic handing capacities; Perhaps, when the message traffic of the MSC of HLR or core net surpasses the numerical value of a setting, the MSC of HLR or core net just sends the OVERFLOW message of carrying LEVEL (level) parameter to the opposite end, and represents above-mentioned traffic handing capacity information or message traffic information by the value of LEVEL parameter.

After described opposite end receives above-mentioned OVERFLOW message, will be according to the value of the LEVEL parameter of carrying in the OVERFLOW message, reduce the message of the transmitting terminal that himself mails to described OVERFLOW message, so that reduce the service traffics and the message traffic of the transmitting terminal of described OVERFLOW message, thereby the safety of the system of assurance makes system that certain other QoS of level can be provided.

Recover just often when the overall traffic handing capacity of the transmitting terminal of described OVERFLOW message or at some office direction traffic handing capacities or message traffic, just value from the LEVEL parameter of carrying to the opposite end that send is 0 OVERFLOW message, the expression Flow Control finishes, after described opposite end received this OVERFLOW message, MSC and HLR just recovered normal business service.
