The implementation to technical solution of the present invention is described in further detail the grid schematic diagram that-Fig. 1 is the present invention below in conjunction with the accompanying drawings, shows the system architecture of the present invention：By SCP (service control points）, SSP (Service Switching Points）, accounting server, the composition such as Service Maintenance Terminal and various telephone-switching networks.

In Fig. 1, SCP is connected with SSP, and using CAP, ((mobile network strengthens the customization application of logic to CAMEL）Application protocol）, WIN (wireless intelligent networks）, INAP (intelligent network application protocols）, SIP (SIPs）Deng as communication protocol, for Service Trigger Information, call proceeding information, call status information etc..SCP can be support multi-protocols package such as supports CAP, SIP or only supports a kind of equipment of intelligent network protocol, this equipment can have AS (the APPLICATION SERVER, i.e. application server of current broadband network concurrently）Or PARLAY gateway capacities.Connection between SSP and exchange network (wireless network, cable network) is that signalling system No.7 and speech channel are relayed, or broadband bag (PACKET) network such as IP network；SSP equipment can be GSM (Global Link digital mobile telephone networks）, CDMA (CDMA multiplexings）The MSC of network, can also be the MSC SERVER (Mobile Switching Center Server of 3G network）Or IMS (IP multimedia subsystem）CSCF (Call Session Con-trol Function, CSCF）Equipment.

Compared with Traditional IN pre-payment, the business logic software that the present invention is loaded on SCP does not handle the logic related to charging, remaining sum, these functions change to be completed by accounting server, User Status data of the SCP only in the system decide whether call establishment, the number and status data of each service-user are stored in scp database, and state includes：Normally, arrearage, suspend operation, report the loss, freezing, be not used etc..User Status can also play voice message to user for SCP and provide reference.

As shown in figure 1, some accounting servers pass through TCP/IP (transmission control protocols/Internet Protocol with SCP）Network is connected.User's detailed data related to prepayment service, including Subscriber Number, remaining sum, state, the business term of validity, tariff level, charging privileges scheme etc. are stored in database on accounting server.Accounting server also assume responsibility for the execution of pre-payment related service logic instead of SCP, include rate configuration, cost of the phone call to calculate, update user balance, produce the functions such as analytical statement, and when User Status changes, User Status is updated onto SCP in time.

Accounting server can use PC server on hardware, and can select free operating system, database, to reduce cost.On function distinguishing, a Service Maintenance Terminal can be specially set, used In operation software upgrading, charging configuration, check form etc..

Fig. 2 is the flow chart for the method that the embodiment of the present invention realizes pre-payment, by taking the application in GSM network as an example, and SCP does not ask accounting server to calculate the maximum duration of call.

Step 110, during bid, SSP reports IDP message to SCP；

Step 120, SCP is received after IDP message, checks the status data of the prepaid user of charging the need for being locally stored, if it is determined that allow call, performs step 130, if not allowing call, performs step 230;

Step 130, SCP issues RRBE message to SSP, indicates SSP registration inspection Check point notification events；Step 140, SCP sends AC message, CONTINUE message to SSP, indicates SSP replay calls；

Step 150, SSP is according to SCP instruction replay call, and such as continue success, starts call；Step 160, after end of calling（It is probably after end of conversation or to continue unsuccessful between calling and called）', SSP reports E B (event report) message, notification event to SCP, and reports ACR (Apply Charging Report) message, reports the duration of call；

Step 170, SCP sends RC (call release) message to SSP, and call flow terminates；Step 180, SCP, which sends to call, reports that indicating that accounting server is conversed this to accounting server performs Prepaid Service Logic, such as charging, renewal user balance；

Calling report includes the call-informations such as calling number, called number, call start time, end of conversation time, caller location, called position, flow mark (calling procedure, called flow, call forwarding etc.).

Step 190, accounting server is received after SCP message, perform Prepaid Service Logic, and when User Status change renewal local data base User Status；

Performing Prepaid Service Logic includes to user's charging, updates the operations such as local data base user balance, generation ticket, and can further update relevant statistical report form data；

In order to ensure the reliable diffusion of calling report, retransmission mechanism is used between SCP and accounting server, SCP caches this communicating data, if in timer scope after calling report is sent to accounting server Accounting server response is not received inside, it tries retransmit, to ensure the accurate billing to user.

Step 200, accounting server is returned to SCP and responded, and current User Status is carried in the response message；

Step 210, SCP is received after the response of accounting server, judges whether User Status changes, if it is, performing step 220, otherwise, is directly terminated；

Step 220, SCP updates the User Status in local data base, terminates；

Step 230, SCP issues RC message to SSP, indicates SSP call releases and play voice message user to be unable to replay call, and SSP call releases terminate.

Fig. 3 shows signaling process during above-described embodiment method call establishment, and Fig. 4 shows signaling process when not allowing call establishment.

In another embodiment, subscriber arrearage is not allowed, therefore, SCP needs to know the duration of call of permission in advance to prescribe a time limit to call.The flow of the embodiment method and above-described embodiment are essentially identical, distinguish as follows：

SCP is as determined to allow after call in the step 120, CHECK-ACC (inspection Check user accounts) message is first sent to accounting server, message includes the parameters such as calling number, called number, call setup time, user current location, flow mark (calling procedure, called flow, call forwarding etc.)；After accounting server is received, CALL-DURATION (duration of call can be used) message is returned to, parameter includes allowing the maximum duration of caller incoming call.Then step 130 is performed again;And in the communication process of later step 150, the duration of call of such as calling and called has reached the maximum duration of call, then SCP indicates that SSP disconnects call by force, performs step 160.Other steps of calling procedure and the flow of above-described embodiment are all identicals.

Fig. 5 shows the GSM network signaling process for precalculating the embodiment of call establishment after the maximum duration of call.

In addition, User Status may also because user registration report the loss, business of requesting timeout, the term of validity have been arrived, reduce the events such as user's hire charge change, now, can be by accounting server proactive notification SCP.Fig. 5 shows that accounting server updates the message flow after User Status on SCP, is with GSM network Exemplified by situation.In these cases, accounting server is when User Status changes, and updates the User Status in local data base, and sends to SCP the message USER INFO of relevant user information such as User Status;SCP is received after message, updates local data base, and responds accounting server, to ensure that the renewal to User Status will not lose.

In summary, pass through above-mentioned system and method, software (business) on accounting server does not influence user to call when updating, and it is unrelated with specific switching equipment, exchange network, intelligent network protocol, facilitate more business software provider production prepayment services, processing business and updates speed is accelerated, and user is not interfered with during the upgrading of prepayment service software, accounting server and is made a phone call；Accounting server uses PC server, reduces equipment cost, is connected by SCP with switch network rather than Service Process Server is connected with switch network, solves equipment compatibility, Web-compatible sex chromosome mosaicism.

The inventive method also can sample be applied to PHS (personal handyphone systems）, GSM, CDMA, PSTN (PSTN）Network and other all circuit-switched networks, and broadband network such as IP based network NGN (next generation networks）Switch network, IMS network etc..In other networks, its flow is essentially identical, signaling message title, the change of parameter name between only SSP and SCP.
