The message of the described inspection talking state of steps A comprises: call identification;
Step B is described to be judged as: judge whether to receive the inspection talking state response message that comprises same call identification, if receive, it is normal then to be defined as conversation, otherwise it is unusual to be defined as conversation.
Described call identification generates when MSC is terminal foundation calling.
Describedly judge whether to receive that the inspection talking state response message that comprises same call identification is specially:
Judge whether to receive and check the talking state response message that if do not receive, it is unusual then to be defined as conversation; Otherwise judge whether call identification is identical with call identification in the inspection talking state message that sends in the inspection talking state response message of receiving, if identical, it is normal then to be defined as conversation, otherwise it is unusual to be defined as conversation.
This method further comprises: set in advance timer and duration thereof;
Described judge whether to receive check that the talking state response message is specially: MSC sends to terminal and starts timer after status message is checked in conversation, and whether the time of examine talking state response message such as judgement surpasses timer duration, if surpass, then be defined as not receiving, otherwise be defined as receiving.
This method further comprises: be defined as returning steps A after the conversation normally.
The message of described inspection talking state is: twinkle SM Flash With Information message;
Described inspection talking state response message is that Flash With Information replys ACK message.
Described call identification carries with label TAG cell.
The present invention is in communication process, and MSC judges whether to receive the inspection talking state response message of corresponding same calling after sending the message of checking talking state to terminal, if receive, it is normal then to be defined as conversation, otherwise it is unusual to be defined as conversation.
The present invention has following beneficial effect:
Because MSC can be known terminal use's talking state, and can need accurately judge whether call release, when the appearance conversation is unusual, MSC can in time discharge the conversation resource, can avoid user's communication to finish also to take the situation of resource thus, improve the utilance of MSC resource, guarantee that the resource among the MSC fully is utilized.

Embodiment
The present invention is in communication process, and MSC judges whether to receive the inspection talking state response message of corresponding same calling after sending the message of checking talking state to terminal, if receive, it is normal then to be defined as conversation, otherwise it is unusual to be defined as conversation.
Judgement of the present invention can be by carrying call identification at MSC in the message that terminal issues, and carry out according to whether receiving the response message that comprises same call identification.
Following with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
Fig. 1 is for providing the process schematic diagram of called number in the embodiment of the invention, this process comprises following steps:
Step 101:MSC sends the inspection talking state message that comprises call identification to terminal.
According to prior art, described call identification generates when MSC is terminal foundation calling, and is carried by label (TAG) cell usually.The message that MSC sends to terminal generally is to be transmitted by BS.
The described inspection talking state of step 101 message can be twinkle SM (Flash With Information) message, be to be handed down to terminal after the MSC structure Flash With Information message, carry call identification in the described Flash WithInformation message, described call identification can carry with the TAG cell.
Described Flash With Information message has description in agreement, stipulate in the agreement, and after MSC sent Flash With Information message BS, BS can be that former state sends to terminal with Flash With Information message transparent transmission.TAG cell in the described agreement in the Flash With Information message is an optional parameters.
The described inspection talking state response message of receiving corresponding same calling that judges whether is specifically as follows: judge whether to receive and check the talking state response message that if do not receive, it is unusual then to be defined as conversation; Otherwise judge that call identification that the inspection talking state response message receive comprises is whether identical with call identification in the inspection talking state message that sends, if identical, it is normal then to be defined as conversation, otherwise it is unusual to be defined as conversation.
Described judge whether to receive check the talking state response message, can if overtime, then be defined as not receiving, otherwise be defined as receiving according to time of examine talking state response messages such as MSC overtime carrying out whether.Usually, MSC can set in advance a time value that issues examine talking state response messages such as checking after the talking state message, and utilizes timer to carry out overtime judgement, and length of timer is set time value, described time value can be provided with arbitrarily, such as being set to 6 seconds etc.
In step 102～step 104,, then can return step 101 usually if it is normal to be defined as conversation.After normally terminal begins conversation, MSC will carry out timing to the calling of terminal, and in timing behind certain hour, execution in step 101 sends the inspection talking state message that comprises call identification to terminal, if it is normal to be defined as conversation in step 102～step 104, then returns step 101 and come to send the inspection talking state message that comprises call identification to terminal again.Here, MSC can regularly send the inspection talking state message that comprises call identification to terminal, and the time interval of talking state message is checked in twice transmission, can be provided with arbitrarily in advance by MSC, such as being set to 30 seconds etc., the time interval between any twice message can be identical or different.
In the present embodiment, if the described inspection talking state of step 101 message is Flash WithInformation message, then the described inspection talking state of step 102 response message is replied (ACK) message for Flash WithInformation.According to stipulating in the agreement that the Flash WithInformation ACK message that BS can return terminal passes through MSC.
In the present embodiment, if MSC comprises the TAG cell in the step 101 in the Flash With Information message that terminal sends, after then terminal was received Flash With Information message in conversation, meeting returned to MSC with the value former state of TAG in the Flash With Information ACK message of returning.According in the agreement to the regulation of TAG cell, after terminal sent to BS with the TAG cell, BS must pass through the TAG cell MSC side.
Accordingly, after MSC receives Flash With Information ACK message, can judge whether the TAG value received in the Flash With Information ACK message is identical with TAG value in issuing Flash With Information message, if identical, it is still normal then can to confirm as this call conversation; If different, it is unusual then to be defined as conversation.
In addition, terminal can not be to MSC echo reply message not when talking state, and MSC will think and not receive inspection talking state response message behind the timer expired of wait acknowledge message, and then determine that conversation is unusual.
MSC be defined as terminal call unusual after, can discharge resource, also can send corresponding message usually and notify BS to take out stitches to BS.
The above is preferred embodiment of the present invention only, is not to be used to limit the scope of application of the present invention.
