Step 110, during bid, SSP reports IDP message to SCP;
Step 120 after SCP receives IDP message, checks the prepaid user's that the local needs of storing charge status data, if determine to allow conversation, execution in step 130 is conversed execution in step 230 if do not allow;
Step 130, SCP issues RRBE message and gives SSP, indication SSP registration checkpoint notification event;
Step 140, SCP sends AC message, CONTINUE message to SSP, indication SSP replay call;
Step 150, SSP is according to the indication replay call of SCP, as continues successfully, begins conversation;
Step 160, behind the end of calling (may be between calling and called behind the end of conversation or continue unsuccessful), SSP reports ERB (event report) message to SCP, notification event, and report ACR (Apply Charging Report) message, the report duration of call;
Step 170, SCP sends RC (call release) message and gives SSP, and call flow finishes;
Step 180, SCP sends to call out and reports to accounting server indication accounting server to this conversation execution prepayment service logic, as chargeing, upgrade user balance etc.;
Comprise calling number, called number, call start time, end of conversation time, caller location, called position, flow process sign call-informations such as (calling procedure, called flow, calling transfers etc.) in this calling report.
After step 190, accounting server are received the message of SCP, carry out the prepayment service logic, and when User Status changes, upgrade the User Status of local data base;
Carry out the prepayment service logic and comprise user's charging, upgrade operations such as local data base user balance, generation ticket, and can further upgrade relevant statistical report form data;
In order to guarantee to call out the reliable transmission of report, adopt retransmission mechanism between SCP and the accounting server, SCP is after the transmission calling reports to accounting server, this communicating data of buffer memory, if in the timer scope, do not receive the accounting server response, then attempt retransmitting, to guarantee the accurate billing to the user.
Step 200, accounting server returns response to SCP, carries current User Status in response message;
Step 210 after SCP receives the response of accounting server, judges whether User Status changes, if, execution in step 220, otherwise, directly finish;
Step 220, SCP upgrades the User Status in the local data base, finishes;
Step 230, SCP issues RC message and gives SSP, indication SSP call release and play the voice suggestion user can not replay call, the SSP call release finishes.
Signaling process when Fig. 3 shows above-described embodiment method call establishment, Fig. 4 shows the signaling process when not allowing call establishment.
In another embodiment, do not allow subscriber arrearage, therefore, SCP need know in advance that the duration of call of permission is to prescribe a time limit to conversation.Flow process and above-described embodiment of this embodiment method are basic identical, distinguish as follows:
SCP is as after determining to allow conversation in step 120, send CHECK_ACC (inspection user account) message earlier to accounting server, comprise calling number, called number, call setup time, user's current location, flow process sign parameters such as (calling procedure, called flow, calling transfers etc.) in the message; After accounting server is received, return CALL_DURATION (the available duration of call) message, comprise the maximum duration that allows the caller incoming call in the parameter.And then execution in step 130; And in the communication process of later step 150, having reached as the duration of call of calling and called should the maximum duration of call, and then SCP indication SSP disconnects conversation, execution in step 160 by force.Other step of calling procedure all is identical with the flow process of above-described embodiment.
Fig. 5 shows the GSM network signal flow process of calculating this embodiment of call establishment after the maximum duration of call in advance.
In addition, User Status also may because of user registration report the loss, request timeout business, the term of validity to, reduce event such as user's hire charge and change, at this moment, can be by accounting server proactive notification SCP.Fig. 5 shows accounting server and upgrades message flow after SCP goes up User Status, is that situation with the GSM network is example.In these cases, when accounting server changes in User Status, upgrade the User Status in the local data base, and send the message USERINFO of relevant user profile such as User Status to SCP; After SCP receives message, upgrade local data base, and the response accounting server, can not lose the renewal of User Status guaranteeing.
