Embodiment 2

The group of the present embodiment is numbered 1111111111 group user A (its number is 8613905190600) and all signing vpn services of user B (its number is 8613905190601), user A is as caller, dial the user B of same group, the two is all user in common net.The short codes of user A is 61000, and the short codes of user B is 61001, and the SCP in the present embodiment describes as an example of the SCP of master home example, referring to Fig. 3, comprises the following steps for the charging method of calling subscriber's vpn service:

Step S301: the MSC at calling subscriber A place receives after call request, the HLR belonging to user A inquires the Originating CAMEL Subscription Information O_CSI (CAMEL user signing contract information Origination-CAMEL SubscriptionInformation starts) of user A.

Step S302: the MSC at calling subscriber A place, send IDP (Initial Detection Point according to the Originating CAMEL Subscription Information O_CSI of user A, start detection point) signaling is to the SCP of user A ownership, triggers the signing vpn service of user A, the information such as numbers of calling and called parties are brought.

Step S303: the SCP of calling subscriber A ownership judges group's information of calling subscriber A, and type of call, selects billing scheme.

Step S304: the SCP transmission CCR (Credit-Control-Request, expense control request) of calling subscriber A ownership (Initial_request) message, to OCS, applies for User Status and the avail information of calling subscriber A.

CCR message comprises: calling procedure mark, calling subscriber group numbering, calling subscriber's MSISDN (Mobile Station ISDN Number, mobile site integrated service digital coding) number, calling subscriber's short codes, called subscriber's Mobile Subscriber International ISDN Number (being long code), called subscriber's short codes, calling subscriber's type of call, caller location information, application resource type mark (duration or the amount of money), calling subscriber's closed user group number, calling subscriber's net nickname code character group number.

Step S305:OCS judges calling subscriber's state and avail information according to interface message, by CCA (Credit-Control-Acknolegement, expense control response) (CC-money returns to user's avail) message return to SCP.

Step S306: the SCP of calling subscriber A ownership, according to calling subscriber's state and avail information, carries out charging control to user, and calculating user can call duration.If calling subscriber's state is normal and have call duration to use, allow calling subscriber to call out, flow process goes to step S307; Otherwise flow process goes to step S320.

This step can also be specially: SCP judges calling subscriber's state information, if calling subscriber's state is undesired, goes to step S320.If calling subscriber's state is normal, SCP gives calling subscriber's balance amount information, billing scheme, rear subscriber number, called number, caller current location information and called current location information etc. the accounting module of SCP, calculates user can use call duration by the accounting module of SCP.The call duration that the accounting module of SCP is calculated is as calling subscriber's available call duration.

Step S307～step S309: the SCP of calling subscriber A ownership issues RRBE (Request report BCSM event, request report BCSM event; Wherein, BCSM is Basic Call State Model BCSM, Basic Call State Model), AC (Apply Charging, Apply Charging), Continue (continuation) signaling, to MSC, requires MSC replay call.

Step S310: after the available call duration of calling subscriber A first application is finished, MSC reports ACR (Apply Charging Report, Apply Charging Report) signaling, and the call duration of calling subscriber A is sent up.

Step S311: the SCP of calling subscriber A ownership sends CCR (Update_request, update request) message to OCS, continuation application calling subscriber state and avail information.

Step S312:OCS judges calling subscriber's state and avail information according to interface message, and returns to SCP.

Step S313: the SCP of calling subscriber A ownership, according to calling subscriber's state and avail information, carries out charging control to calling subscriber, and calculating calling subscriber can call duration.If calling subscriber's state is normal and have call duration to use, allow calling subscriber to call out, flow process goes to step S3014.Otherwise flow process goes to step S3017.

Step S314: the SCP of calling subscriber A ownership issues AC (Apply Charging, Apply Charging) signaling to MSC, requires MSC to continue to call out.

Step S315: after end of calling, MSC reports ERB (O-disconnect, caller take out stitches event) to SCP.

Step S316: after end of calling, MSC reports ACR signaling to SCP, and calling subscriber's call duration is sent up.

Step S317: the SCP of calling subscriber A ownership, according to selected billing scheme and call duration, calculates this calling charge of calling subscriber A, and goes out caller ticket.

Step S318: the SCP of calling subscriber A ownership sends CCR (Terminate_request) message to OCS, by calling subscriber A, this calls out cost of use information notification OCS.

When calling procedure end of calling reports OCS to call out object information, CCR message comprises: calling procedure mark, calling subscriber group numbering, calling subscriber's Mobile Subscriber International ISDN Number (being long code), calling subscriber's short codes, called subscriber's Mobile Subscriber International ISDN Number (being long code), called subscriber's short codes, calling subscriber's type of call, caller location information, call duration, call out the amount of money of consuming, the resource type mark using, calling subscriber's closed user group number, calling subscriber's net nickname code character group number.

Step S319:OCS deducts this calling charge of calling subscriber A according to interface message, and the result of deducting fees returns to SCP.

Step S320: the SCP of calling subscriber A ownership sends RC (Release Call, call release) message to MSC, call release.

Referring to Fig. 4, step S303 specifically comprises the following steps:

Step S400:SCP receives calling, determines that call flow is calling procedure.

Step S401:SCP, according to calling subscriber's Mobile Subscriber International ISDN Number, judges at this scp database whether calling subscriber is the user of the virtual group of this SCP; Go to step S402 if not this SCP virtual group user; Otherwise go to step S403.

Step S402:SCP judges that called number is called subscriber's short codes or called subscriber's Mobile Subscriber International ISDN Number (long code).If called subscriber's Mobile Subscriber International ISDN Number goes to step S404; Short codes goes to step S405.

Step S403:SCP judges whether calling number or calling subscriber place group block.If blocked, step S405; Otherwise go to step S406.

Step S404:SCP directly continues and exhales, and no longer carries out charging control.

Step S405:SCP call release.

Step S406:SCP judges according to called number whether calling subscriber and called subscriber are the user of same group, if so, go to step S407; Otherwise go to step S408.

If called subscriber's number is Mobile Subscriber International ISDN Number, SCP will utilize whether calling number and called MS ISDN number are the users of same group on this SCP in local data library inquiry numbers of calling and called parties; If called subscriber's number is short codes, SCP will utilize whether calling number and called short codes are the users of same group on this SCP in local data library inquiry numbers of calling and called parties.

Step S407: if calling and called user is the user of same group, further judge whether calling and called user is closed user group user in net.If calling and called user is not same closed user group, go to step S409.Otherwise go to step S410.

Step S408: if calling and called user is not the user of same group, further judge whether called subscriber is the net nickname code character user of caller group.If called subscriber is the net nickname code character of caller group, go to step S411.Otherwise go to step S412.

Step S409: determine that type of call is the common on-net call of group, select caller billing scheme in group's common net.

Step S410: determine that type of call is closed user groupcall in group network, selects closed user group caller billing scheme in group network.

Step S411: determine type of call be the group calling of group network External Number, select group network nickname code character caller billing scheme.

Step S412: determine that type of call is group network outcall, the outer caller billing scheme of group network.

In the present embodiment, user A and user B are domestic consumers in same group network, execution step S409, and selecting billing scheme is call charging scheme in group's common net.

In step S304, suppose that SCP sends to each Field Definition of CCR message of OCS as shown in table 1 below:

Table 1

Message field	Value explanation
		Flow process mark	1-calling procedure, 2-called flow, 3-forward flow process
Calling number	Calling subscriber's Mobile Subscriber International ISDN Number (long code)
		Called number	Called subscriber's Mobile Subscriber International ISDN Number (long code)
Caller short codes	Calling subscriber's short codes
		Called short codes	Called subscriber's short codes
Type of call	1 common on-net call, closed user groupcall in 2 nets, 3 net External Number group callings are, 4 common net outcall
		User's fee current location information	The current place of user's fee area code, calling procedure refers to calling number current location, called flow refers to called number current location
The resource type mark of application	1-applies for the amount of money, and 2-applies for duration
		User group's numbering	User group's numbering
Closed user group number in user network	Closed user group number in user network
		User network nickname code character group number	User network nickname code character group number

In the present embodiment, each field value of CCR message is as shown in table 2:

Table 2

Further, suppose that in step S305 OCS returns in the CCA message of SCP each Field Definition as shown in table 3 below:

Table 3

Message field	Value explanation
		User Status	0-un-activation, 1-is normal, 2-retention period, 3-pool period, 4-deletes the phase
User balance	The current remaining sum of calling subscriber

Only having User Status is 1, and caller remaining sum is greater than in 0 situation and just allows to call out.

The logic of step S303 in the present embodiment and charging wholesale price authentication logic are just to exist in original vpn service, therefore needn't this service logic of overlapping development while utilizing the method to realize vpn service, and then avoided the overlapping development of hardware and the overlapping investment of hardware device.

Embodiment 3

The group of the present embodiment is numbered 1111111111 group user A (its number is 8613905190600) and all signing vpn services of user B (its number is 8613905190601), user A is as caller, dial the user B of same group, the two is all user in common net.The short codes of user A is 61000, and the short codes of user B is 61001, referring to Fig. 5, comprises the following steps for the charging method of called subscriber's vpn service:

Step S501-step S502: calling subscriber A calls out access MSC and sends SRI message to called subscriber B ownership HLR, called ownership HLR returns to called subscriber B CAMEL-Subscription-Information O_CSI+T_CSI (Termination-CAMEL Subscription Information, terminating CAMEL user signing contract information), calling subscriber A calls out access MSC by the address that obtains called subscriber B ownership SCP in T_CSI data, to called subscriber B ownership, SCP sends IDP message, triggers the vpn service of called subscriber B.

Step S503: the SCP of called subscriber B ownership judges group's information, user profile, type of call, the billing scheme of selection called subscriber B.

Step S504: the SCP that called subscriber B belongs to sends CCR (Initial_request) message to OCS, application called subscriber condition and avail information.

When called flow can be used for the amount of money of calling to OCS application user, CCR comprises: called flow mark, called subscriber group numbering, calling subscriber's Mobile Subscriber International ISDN Number (being long code), calling subscriber's short codes, called subscriber's Mobile Subscriber International ISDN Number (being long code), called subscriber's short codes, called subscriber's type of call, called positional information, application resource type mark (duration or the amount of money), called subscriber's closed user group number, called subscriber's net nickname code character group number.

Step S505:OCS judges called subscriber condition and avail information according to interface message, and returns to the SCP that called subscriber belongs to.

Step S506: the SCP that called subscriber belongs to, according to called subscriber condition and avail information, carries out charging control to called subscriber, calculating called subscriber can call duration.If called subscriber condition is normal and have call duration to use, allow called subscriber to call out, flow process goes to step S507; Otherwise flow process goes to step S521.

For example, SCP judges called subscriber's state information, if called subscriber's state is undesired, goes to step S521.If state is normal, called subscriber's balance amount information, billing scheme, rear subscriber number, called number, caller current location information and called current location information etc. are sent to the accounting module of SCP, calculate called subscriber by the accounting module of SCP and can use call duration.The call duration that the accounting module of SCP is calculated is as called subscriber's available call duration.

Step S507～step S509: the SCP of called subscriber B ownership issues RRBE, AC and Connect signaling arrives MSC, requires MSC replay call.

Step S510: the MSC at the current place of calling subscriber A is according to called MS RN (Mobile Station Roaming Number, mobile station roaming number) continuing called subscriber B.

Step S511: after the available call duration of called subscriber B first application is finished, MSC reports ACR signaling, and called subscriber's call duration is sent up.

Step S512: the SCP that called subscriber B belongs to sends CCR (Update_request) message to OCS, continuation application called subscriber condition and avail information.

Step S513:OCS judges called subscriber condition and avail information according to interface message, and returns to SCP.

Step S514: the SCP of called subscriber B ownership, according to User Status and avail information, carries out charging control to called subscriber B, and calculating called subscriber B can call duration.If called subscriber B state is normal and have call duration to use, allow called subscriber B to call out, flow process goes to step S515; Otherwise flow process goes to step S517.

Step S515: the SCP of called subscriber B ownership issues AC signaling to MSC, requires MSC to continue to call out.

Step S516: call stops, and the MSC of calling subscriber A reports ACR, the SCP by the call duration information band of called subscriber B to called subscriber B ownership.

Step S517: the SCP of called subscriber B ownership, according to selected billing scheme and call duration, calculates this calling charge of called subscriber B, and go out the ticket of called subscriber B.

Step S518: the SCP of called subscriber B ownership sends CCR (Terminate_request) message to OCS, by called subscriber B, this calls out cost of use information notification OCS.

Called flow end of calling, when reporting OCS to call out object information, SCP can comprise in CCR message: called flow mark, called subscriber group numbering, calling subscriber's Mobile Subscriber International ISDN Number (being long code), calling subscriber's short codes, called subscriber's Mobile Subscriber International ISDN Number (being long code), called subscriber's short codes, called subscriber's type of call, called positional information, call duration, call out the amount of money of consuming, the resource type mark using, called subscriber's closed user group number, called subscriber's net nickname code character group number.

Step S519:OCS deducts this calling charge of user according to interface message, and the result of deducting fees returns to SCP.

Step S520: caller access MSC reports onhook event (ERB).

Step S521:SCP issues call release signaling (RC) to caller access MSC.

Preferably, the idiographic flow of step S503 is as shown in Figure 6:

Step S600:SCP receives calling, determines that call flow is called flow.

Step S601:SCP, according to called subscriber's Mobile Subscriber International ISDN Number, judges at this scp database whether called subscriber is the user of the virtual group of this SCP; Go to step S602 if not this SCP virtual group user; Otherwise go to step S603.

Step S602:SCP call release.

Step S603:SCP judges whether called number or called subscriber place group block.If so, execution step S602; Otherwise go to step S604.

Step S604:SCP judges according to calling number whether calling subscriber and called subscriber are the user of same group, if so, go to step S605; Otherwise go to step S606.

If calling subscriber's number is Mobile Subscriber International ISDN Number, SCP will utilize whether caller Mobile Subscriber International ISDN Number and called MS ISDN number are the users of same group on this SCP in local data library inquiry numbers of calling and called parties; If calling subscriber's number is short codes, SCP will utilize whether caller short codes and called MS ISDN number are the users of same group on this SCP in local data library inquiry numbers of calling and called parties.

Step S605～step S610 is identical with step S407～step S412, repeats no more here.

In the present embodiment, user A and user B are closed user group users in same group network, execution step S608, and selecting billing scheme is the called billing scheme of closed user group in group network.

Preferably, suppose that SCP in step S504 sends in the CCR message of OCS each Field Definition as shown in table 4:

In above-described embodiment, the logic of step S503 and charging wholesale price authentication are just to exist in original vpn service, utilize the method to realize vpn service, needn't this service logic of overlapping development.

Embodiment 4

The group of the present embodiment is numbered 1111111111 group user A (its number is 8613905190600) and all signing vpn services of user B (its number is 8613905190601), user A is as caller, dial the user B of same group, user B is provided with Call Forwarding No Reply business, its forwarding subscriber is user C, transferred number is C number 8613905190602, and user C is the outer user of net.The short codes of user A is 61000, and the short codes of user B is 61001.

Referring to Fig. 7, comprise the following steps for the charging method of the vpn service of called subscriber's forward flow process:

Step S701: after user B called flow triggers, the calling access MSCa/VLR/SSP of user A sends SRI signaling to the HLRb of user B ownership, and HLRb returns to the MSRN of user B in SRI_ACK.The calling access MSCa/VLR/SSP of user A continues according to the MSRN of user B, user B nonreply.MSCb/VLR/SSP sends the SCPb of IDP to user B ownership, triggers the forward flow process IN service of user B.

Step S702: the SCP of forwarding subscriber B ownership judges group's information of calling subscriber B, and type of call, selects billing scheme.

Step S703: the SCP that forwarding subscriber B belongs to sends CCR (Initial_request) message to OCS, application forwarding subscriber B state and avail information.

When in forward flow process, SCP can be used for the amount of money of calling to OCS application forwarding subscriber, CCR message comprises: forward flow process mark, there is group's numbering of forwarding subscriber, there is the user's of forward Mobile Subscriber International ISDN Number (being long code), there is the user's of forward short codes, the user's who is forwarded to Mobile Subscriber International ISDN Number (being long code), be forwarded to user's short codes, the type of call of forwarding subscriber, original calling number, there is forwarding subscriber positional information, application resource type mark (duration or the amount of money), the closed user group number of forwarding subscriber, the net nickname code character group number of forwarding subscriber.

Step S704:OCS, according to interface message, judges forwarding subscriber B state and avail information, and returns to SCP.

Step S705: the SCP that forwarding subscriber B belongs to, according to its state and avail information, carries out charging control to forwarding subscriber B, calculating user can call duration.If forwarding subscriber B state is normal and have call duration to use, allow forwarding subscriber B to call out, flow process goes to step S706; Otherwise flow process goes to step S724.

For example, SCP judges the state information of forwarding subscriber, if the state of forwarding subscriber is undesired, go to step S724, if state is normally,, the accounting module that user's balance amount information, billing scheme, forwarding subscriber number, the Subscriber Number being forwarded to, conversion family current location information, user's current location information of being forwarded to etc. is sent to SCP, calculates forwarding subscriber by the accounting module of SCP and can use call duration.The call duration that the accounting module of SCP is calculated is as the available call duration of forwarding subscriber.

Step S706～step S708: the SCP that forwarding subscriber B belongs to issues RRBE, AC and Connect signaling arrives MSCb, requires MSCb replay call.

Step S709～step S718:MSCb/VLR/SSP receives after Connect, sends SRI message to the HLRc of C number home, and HLRc initiates PRN to MSCc/VLR/SSP, and request MSCc/VLR/SSP returns to C number roaming number.MSCc/VLR responds PRN_ACK message to HLRc, carries C number MSRN.The SRI_ACK message that MSCb/VLR/SSP responds by HLRc obtains C number MSRN.MSCb/VLR/SSP replay call, converses between user A and user C.

Step S719: after end of calling, MSCb reports ERB to forwarding subscriber SCP that B belongs to.

Step S720: after end of calling, MSCb reports ACR signaling to forwarding subscriber SCP that B belongs to, and the call duration of forwarding subscriber B is sent up.

Step S721: the SCP that forwarding subscriber B belongs to, according to selected billing scheme and call duration, calculates this calling charge of forwarding subscriber B, and goes out forward ticket.

Step S722: the SCP that forwarding subscriber B belongs to sends CCR (Terminate_request) message to OCS, by forwarding subscriber B, this calls out cost of use information notification OCS.

Forward flow process end of calling, when SCP reports OCS to call out object information, CCR message comprises: forward flow process mark, there is group's numbering of forwarding subscriber, there is the user's of forward Mobile Subscriber International ISDN Number (being long code), occur forward user short codes, the user's who is forwarded to Mobile Subscriber International ISDN Number (being long code), be forwarded to user's short codes, the type of call of forwarding subscriber, original calling number, there is forwarding subscriber positional information, call duration, call out the amount of money of consuming, the resource type mark using, the closed user group number of forwarding subscriber, the net nickname code character group number of forwarding subscriber.

Step S723:OCS, according to interface message, deducts this calling charge of forwarding subscriber B, and the result of deducting fees returns to SCP.

Step S724: the SCP that forwarding subscriber B belongs to sends RC (Release Call, call release) message to MSCb, call release.

Preferably, suppose that SCP in step S703 sends in the CCR message of OCS each Field Definition as shown in table 7:
