Be that example illustrates an alternative embodiment of the invention in conjunction with Fig. 4 below with the short message service.

Step 401: calling terminal send short messages to calling mobile exchanging center (Mobile SwitchCenter, MSC)/Service Switching Point (Service Switching Point, SSP);

Wherein calling terminal adds before called number and has dialled prefix, as 8888+13XXXXXXXXX or 8888+0086+13XXXXXXXXX.

Step 402:MSC/SSP is according to calling subscriber's CAMEL-Subscription-Information trigger intelligent business, SSP reports start detection point (Initial Detection Point to SCP, IDP) during message, the parameters C alledPartyBCDNumber in this message (called number) comprises the user and adds the prefix of dialling;

Step 403:SCP sends credit control request incident to message accounting, and (Credit Control Request CCR{event}) applies for deducting fees;

Add the called number of having dialled prefix in the transparent transmission IDP message among the CCR{event}.

Step 404: message accounting is selected corresponding pay account according to the prefix of carrying in the called number;

After OCS receives CCR{event} message request from SCP, carry out number analysis, subscription authentication and the operation of deducting fees, specify according to prefix below in conjunction with accompanying drawing 4-1 and select the pre-paid account or the back specific implementation of pay account:

4041: carry out number analysis, peel off professional prefix;

Successively peel off the professional prefix of called number, international prefix, national code, domestic prefix,

The standard number format is: [professional prefix]+[00 (international prefix)+national code]+[0 (domestic prefix)]+{ Subscriber Number }, and wherein [] is expressed as and non-ly must fills out parameter, and { } expression must be filled out parameter.

The professional prefix here can comprise IP prefix, international gateway prefix, individual freephone (P-FPH, Personal-FreePhone) prefix, appointment payment mode prefix etc.

Step 4042: search the prefix types mapping table according to professional prefix table and obtain prefix types;

The prefix types mapping table can comprise following content:

Prefix	Prefix types ID	The prefix types title
			?17951	??1	The IP prefix
?17911	??1	The IP prefix
			?1	??2	The international gateway prefix
?9	??2	The international gateway prefix
			?1234	??3	Individual's freephone prefix
?7777	??4	Specify the payment mode prefix
			?8888	??4	Specify the payment mode prefix

Pre-configured prefix types mapping table on OCS can be searched this table based on the professional prefix in the called number and obtain its corresponding prefix types, and different prefix types will be carried out different tariff policy and payment policies.When being 8888+13XXXXXXXXX, the prefix types that obtains of tabling look-up is " 4-specifies the payment mode prefix " when called.

Step 4043: search the payment mode mapping table, select corresponding pre-paid account or back pay account;

OCS is at the corresponding rate of call applications of " 4-specifies the payment mode prefix ", and carry out corresponding payment policies (pre-payment/later-payment) based on " 4-specify payment mode prefix ", last pre-defined every kind " 4-specifies the payment mode prefix " corresponding pre-paid account or back pay account of OCS, by looking into the pay account that the payment mode mapping table can obtain current prefix appointment:

Prefix	Pay account
		??7777	The 0-pre-payment

Prefix	Pay account
		??8888	Pay behind the 1-

In some cases, can have limit priority by the pre-paid account or the back pay account of prefix appointment, have precedence over the scheme of specifying pay account by type of service or time period etc.

Step 4044: carry out the operation of deducting fees based on the pay account type of searching;

Step 405:OCS sends credit control response incident (CCA{event}) message to SCP, and indication SCP sends this short message and deducted fees successfully;

This CCA{Event} message issues " resetting the indication of purpose routing address " and " purpose routing address " two parameters, value is " 1-is " " to reset the indication of purpose routing address ", and " purpose routing address " is for peeling off the real called party number that adds the professional prefix of dialling;

Step 406:SCP is to send SMS message event request report (Request Report SMEvent) and be connected (Connect) signaling of MSC/SSP;

In CCA{event} message, " reset the indication of purpose routing address " and the indication of " purpose routing address " two parameters according to OCS, issue when continuing by the DestinationRoutingAddress parameter renegotiation new settings route destination address in the Connect order, its parameter value is taken from " purpose routing address " in the CCA{event} response message, and " purpose routing address " is used for switching equipment (MSC/GMSC) continuing to the real called party number.After user's use adds the business of dialling prefix appointment pay account, need to use the Connect order to reset the number that continues of MSC/SSP, promptly remove the called number (0086+13XXXXXXXXX after the prefix, otherwise MSC/SSP acquiescence uses the called number (8888+13XXXXXXXXX) that has prefix short message can't be sent to real user as the number that continues the international number form).

Step 407:MSC/SSP is by sending to SMSC with short message;

Step 408:SMSC receives and returns response message to MSC/SSP after the short message.

In this embodiment, the user can realize selection before pre-paid account and the back pay account flexibly by add the mode of dialling specified prefix before called number when sending SMS message, and makes the user select the pay account of oneself hope to pay when sending SMS message.

In another embodiment of the present invention, if user applies the mixing paying brand of certain operator, its speech business is default sets different pay account on a time period, any phone that (8:00-17:30) dials during being on duty as the user under this brand all uses the pre-paid account payment, and any phone that (17:30-8:00) dials during coming off duty then uses back pay account payment.Simultaneously, this user has applied for that also the way of paying selection is professional, this professional application way can be modes such as traditional calling application, business hall application, after applying for successfully, operator can inform that this user can be by adding the selection that the mode of dialling prefix realizes pay account by modes such as note or artificial notices, in the present embodiment, can set 7777 for selecting pre-paid account to charge, 8888 for selecting the back pay account to charge.Is that example illustrates this programme below in conjunction with Fig. 5 with concrete calling of this user.

Step 501: the calling subscriber adds group prefix and applies for call proceeding before called number;

For example 8888+13XXXXXXXXX or 8888+0086+13XXXXXXXXX;

Step 502:MSC/SSPA is according to calling subscriber's CAMEL-Subscription-Information trigger intelligent business, SSP is when reporting IDP message to SCP, parameters C alledPartyBCDNumber in this message (called number) comprises the user and adds the prefix of dialling, for example: 8888+13XXXXXXXXX;

IDP message major parameter:

Step 503:SCP begins message by Diameter credit control request, and (Credit ControlRequest CCR{Initial}) adds the calling subscriber prefix of dialling and passes through message accounting;

SCP and message accounting are mutual, application subscription authentication, wholesale price and charge future, its interface parameters can mainly comprise information such as calling number, called number, request charging duration, it is consistent with the CalledPartyBCDNumber number in the IDP message that called number wherein keeps, carry the user and add the prefix of dialling, the intact message accounting that passes through, (Online ChargingSystem OCS) is example to the message accounting in the present embodiment with the line message accounting.

Message name	Parameter name (English)	Parameter name (Chinese)	Value is described
				??CCR{Initial}	??[Requested-Ser??vice-Unit]-??[CC-Time]	Request charging duration	300 seconds
	??[Calling-Party-??Address]	Calling number	??13xxxxxxxxx
					??[Called-Party-??Address]	Called number	??8888+13XXXXXXXXX

Step 504: message accounting is selected corresponding way of paying according to the prefix of carrying in the called number;

After OCS receives CCR{Initial} message request from SCP, carry out the budget operation of number analysis, subscription authentication and first request charging duration, specify the specific implementation of selecting pre-paid account or back pay account according to prefix below in conjunction with accompanying drawing 5-1:

5041: carry out number analysis, peel off professional prefix;

With step 4041, do not give unnecessary details herein.

Step 5042: search the prefix types mapping table according to professional prefix table and obtain prefix types;

With step 4042, do not give unnecessary details herein.

Step 5043: search the payment mode mapping table, select corresponding pre-paid account or back pay account;

With step 4043, do not give unnecessary details herein.

In one case, can have limit priority, have precedence over the scheme of specifying pay account by type of service or time period etc. by the pre-paid account of prefix appointment or back pay account.To specify pre-paid account or back pay account below by 7777 (pre-payment)/8888 (paying in the back) prefix is example:

A. called number does not add the default pay account when dialling prefix

Certain mixing paying brand that operator releases, its speech business is default sets different pay account on a time period, any phone that (8:00-17:30) dialed during user under this brand was on duty all uses the pre-paid account payment, and any phone that (17:30-8:00) dials during coming off duty then uses back pay account payment.

B. add the pay account of dialling after the prefix 7777 before the called number

User under this mixing paying brand has opened to add and has dialled prefix and change after the business function of payment mode, no matter be work hours (8:00-17:30) or quitting time (17:30-8:00), the calling of Fa Shenging at any time needs only to add before called has dialled 7777 prefixes, and device will all force to use the pre-paid account payment.

C. add the pay account of dialling after the prefix 8888 before the called number

User under this mixing paying brand has opened to add and has dialled prefix and change after the business function of payment mode, no matter be work hours (8:00-17:30) or quitting time (17:30-8:00), the calling of Fa Shenging has at any time been dialled 8888 prefixes, pay account payment after device will all be forced to use as long as add before called.

Step 5044: carry out the budget operation of first request charging duration with tariff policy based on the pay account type of searching;

Based on the tariff policy of " specify payment mode prefix " type, payment policies finish the budget operation after, the request of being chargeed is first authorized duration and is reserved correlative charges the account of appointment.

Step 505:OCS by credit control response begin (Credit Control Answer, CCA{Initial}) message is returned authenticating result, first charging request mandate available duration via and is given SCP;

Be used to realize IN service owing to add the prefix of dialling, do not need when continuing, so OCS is in the CCA{Initial} response message, also need to return simultaneously " resetting the indication of purpose routing address " and " purpose routing address " two parameters and give SCP, " purpose routing address " is for peeling off the called number (for example: 0086+13XXXXXXXXX, international number form) after the prefix;

CCA{Initial} message major parameter:

Step 506:SCP receives after the CCA{Initial} response message of OCS, issue Apply Charging message (ApplyCharging, AC), provide charge information message (FurnishCharging Information, FCI), connect (Connect) message and give MSC/SSPA;

In CCA{Initial} message, " reset the indication of purpose routing address " and the indication of " purpose routing address " two parameters according to OCS, issue when continuing by the DestinationRoutingAddress parameter renegotiation new settings route destination address in the Connect order, its parameter value is taken from " purpose routing address " in the CCA{Initial} response message; " purpose routing address " is used for switching equipment (MSC/GMSC) continuing to the real called party number.In the ordinary course of things, the called number that the user dialed is consistent with the real called party number, so the default Continue that does not have any parameter that issues of SCP orders the called number conduct that will use MSC/SSP at this moment the user the to dial number that continues to MSC/SSP; After user's use adds the business of dialling prefix appointment pay account, need to use the Connect order to reset the number that continues of MSC/SSP, promptly remove the called number (0086+13XXXXXXXXX after the prefix, otherwise MSC/SSP acquiescence uses the called number (8888+13XXXXXXXXX) that has prefix can't normally be routed to the real called party user as the number that continues the international number form).

Connect orders major parameter:

Message name	Parameter name (English)	Parameter name (Chinese)	Value is described
				?Connect	??DestinationRouting??Address	The purpose routing address	The called number of 0086+13XXXXXXXXX international number form
	??GenericNumbers	Calling number	60+ calling number: 6013xxxxxxxxx

Step 507: caller MSC replay call is to called MS C;

Caller MSC is implemented to the call proceeding of real called party number according to the new route destination address " DestinationRoutingAddress " of Connect order appointment.

Need to prove, calling subscriber's pay account and tariff policy have been determined by above step, handle CCR/CCA{Initial} message at OCS, and issue first AC and Connect through SCP and continue after the order call through, MSC/SSP monitors the whole session process in real time, when the time slicing that issues uses up, between SCP and the message accounting by CCR{Update}/CCA{Update} to using the charging of duration, and next time slicing is reserved in application, when user's call release, SCP triggers CCR{Terminate} message again to OCS, and OCS finishes the charging to last call duration, and stops current sessions by CCA{Terminate} message.

CCR{Update}, number resource, tariff policy and pay account in the CCR{Terminate} message reuse CCR{Initial} message, do not need to report again again information such as calling number, called number, do not need to re-execute again the operation of subscription authentication, number analysis yet, only need carry out to the charging of last time slicing and to the budget/reservation operations of next time slicing getting final product based on the tariff policy that analyzes among the CCA{Initial} and payment policies, and finally in CCR{Terminate} message, generate charging bill.

The scheme that inventive embodiments provides is the real time altering payment mode when per call, has avoided loaded down with trivial details service handling flow process and time waiting.
