Embodiment 2

The embodiment of the present invention provides a kind of method of charging.The present embodiment is applied to the network architecture as shown in Figure 3, in the IMS system, a general AS is set in advance, triggers the OCS charging by general AS, and as shown in Figure 4, the method comprises:

Step 201: the calling subscriber sends call request to CSCF, and wherein, this call request is carried calling number and called number;

Wherein, calling number is used for the sign calling subscriber, and called number is used for the sign called subscriber.The calling subscriber sends call request, and this call request is used for request and converses with the called subscriber.

Step 202:CSCF receives this call request, and this call request is transmitted to general AS;

Wherein, the service provider arranges general AS in advance in the IMS system, general AS is responsible for the call meters of each user in a zone, the service provider arranges one or more CSCF in this zone, calling subscriber in this zone, send call request to one of them CSCF, this CSCF sends to general AS with this call request again.

Step 203: general AS receives this call request, the calling number of carrying according to this call request, from HSS (Home Subscriber Server, the home network client server) obtain the business information that the calling subscriber contracts in advance in, wherein, business information comprises ID, business AS address and the OCS address of business at least;

Wherein, service provider's define grid business, take Network as the one or more logic business of basis definition, and logic business is superimposed upon on Network.The calling subscriber in advance with service provider's Network of contracting, in addition can also be take this Network as the basis and signing other the logic business of service provider, then the business information of service provider's each business that calling subscriber's calling number and calling subscriber contracted is stored in HSS.

Wherein, HSS can store calling subscriber's calling number and the business information that the calling subscriber contracts by the corresponding relation of calling number and business information.Correspondingly,

According to the calling number that call request is carried, the operation of obtaining corresponding business information from HSS is specially: the calling number of carrying according to call request, from the corresponding relation of the calling subscriber of HSS storage and business information, search the business information of correspondence.

Wherein, in the IMS system, have online charging mode and offline charging mode, every kind of mode all is responsible for charging by the OCS of correspondence.The calling subscriber is also this service log-on charging way to signing certain business of service provider in advance, the service provider need to obtain the address of OCS of the charging way of the address of business AS of the ID of the business that the calling subscriber contracts and this business of storage and responsible calling subscriber registration, the address of the ID of the business that the calling subscriber is contracted, the business AS that obtains and the address of OCS be as business information, then this calling subscriber's calling number and business information is stored in HSS.

For example, PPS (Pre-Paid Servie, prepayment service) business is a kind of Network, and VPN (Viirtual Private Network, Virtual Private Network) business is the logic business that is superimposed upon on the PPS business.calling subscriber A and calling subscriber C in advance respectively with the signing PPS business of service provider, and the vpn service of having contracted take the PPS business as basic and service provider, and the charging way that is all both two service log-ons is the online charging mode, wherein, the calling number of calling subscriber A is NumberA, the calling number of calling subscriber C is NumberC, the ID of PPS business is IDpps, the business AS of storage PPS business is PPSAS, and the address of PPS AS is IPpps, the ID of vpn service is IDvpn, the business AS of storage vpn service is VPN AS, and the address of VPN AS is IPvpn, in the IMS system, the address of being responsible for the OCS of online charging is IPocs.the service provider is with the IDpps of PPS business, the address ip pps of PPS AS and the address ip ocs of OCS are as the business information of PPS business, IDvpn with vpn service, the address ip vpn of VPNAS and the address ip ocs of OCS are as the business information of vpn service, corresponding relation with the business information of calling number NumberA and PPS business, the corresponding relation of the business information of calling number NumberA and vpn service, the corresponding relation of the business information of the corresponding relation of the business information of calling number NumberC and PPS business and calling number NumberC and vpn service is stored in respectively in the corresponding relation of calling number as shown in table 1 in HSS and business information.

Table 1

Step 204: general AS obtains rule and policy from management server, from the business information of obtaining, selects business information according to the rule and policy that obtains;

Wherein, general AS can obtain the business information of a Network, can also obtain the business information that is superimposed upon the logic business on this Network.Particularly, general AS obtains rule and policy from management server, if when general AS gets a business information, general AS directly selects this business information, if general AS gets a plurality of business information, select a business information according to the rule and policy that obtains.

For example, rule and policy is set in management server in advance is " priority by business is selected business information ", namely general AS according to the priority of this rule and policy according to each business, selects the business information of the high business of priority.

Correspondingly, go back the ID of storage service and the corresponding relation of priority in advance in general AS.If general AS gets a plurality of business information, general AS is according to the ID of the business in each business information, from the corresponding relation of the ID of business and priority, searches the priority of each business, selects the business information corresponding to business of priority maximum;

Step 205: general AS is according to business information and the calling number selected, obtain the residue amount of business corresponding to the business information of selection from management server, if the residue amount of obtaining is not 0, with the business information selected as the business information for charging, execution in step 206;

Wherein, store the ID of calling number, business and the corresponding relation of residue amount in management server.Particularly, general AS is according to the ID of the business in the business information of calling number and selection, search corresponding residue amount from the corresponding relation of the ID of the calling number of management server stores, business and residue amount, if the residue amount of searching is not 0, execution in step 206.

Wherein, if the residue amount of searching be 0 and also have remaining business information, general AS need to from remaining business information, reselect a business information according to the rule and policy that obtains, and then carry out this step.

Step 206: general AS sends to corresponding business AS according to the address of the business AS of the business information that is used for charging of selecting with this call request;

Step 207: this business AS receives this call request, and can the calling number of carrying according to call request is determined for this calling subscriber provides this business, if can, reply confirmation to general AS;

Wherein, this business AS can determine that can the calling subscriber use this business, no longer describes in detail at this according to existing method.

Wherein, if determining, this business AS can not provide business for this calling subscriber, send notice to general AS, after general AS receives this notice, if also there is remaining business information, from remaining business information, select a business information that is used for charging, begin operation from step 305 again, otherwise, end operation.

Wherein, in the present embodiment, if general AS gets the business information of a plurality of business, select a business information that is used for the business of charging, and the forwarding conversation request gives business AS corresponding to this business information, this business AS judges operation again, so avoided call request is transmitted to business AS corresponding to each business information, then each business AS judges operation, takies resource thereby reduce, and has saved operation cost; In addition, general AS selects a business information that is used for the business of charging from the business information of a plurality of business, and OCS does not need to do the operation of selecting business information again, thereby has shared the some work of OCS, can reduce the equipment investment to OCS.

Step 208: general AS receives this confirmation, according to the address of the OCS in the business information of selecting, sends accounting request to the OCS of correspondence; Wherein, this accounting request is carried the ID of the business in the business information of calling number and selection at least;

Step 209:OCS receives this accounting request, and according to the ID of the calling number in accounting request and business, setting is set aside some time, and sends response message to general AS, and this response message comprises at least sets aside some time;

Particularly, OCS receives this accounting request, carry out wholesale price according to the ID of the business in this accounting request, obtain charging rate, ID according to the calling number of carrying in this accounting request and business, search corresponding residue amount from the corresponding relation of the ID of the calling number of management server stores, business and residue amount, go out cost of the phone call according to charging rate and the Time Calculation of presetting, judge whether cost of the phone call surpasses the residue amount of searching, if surpass, calculate according to residue amount and charging rate and set aside some time; If do not surpass, the time that will set aside some time and be set to preset, send and to carry the response message of setting aside some time to general AS.

Wherein, be specially according to charging rate and the operation that the Time Calculation of presetting goes out cost of the phone call: charging rate and default time are multiplied each other draws cost of the phone call; Calculating the operation of setting aside some time according to residue amount and charging rate is specially: will remain amount and charging rate and be divided by to draw and set aside some time.The ID of calling number, business and the corresponding relation of residue amount are set in OCS in advance.

Wherein, existing multiple method of carrying out wholesale price according to the ID of business, for example, can arrange the ID of business and the corresponding relation of price in advance in OCS at present, and wherein, each business can corresponding one or more prices.

Therefore, OCS carries out the operation of wholesale price according to the ID of the business that accounting request is carried, be specially: OCS receives this accounting request, according to the ID of the business of carrying in this accounting request, from the corresponding relation of the ID of business and price, search corresponding price, if find out a plurality of prices, according to default price of policy selection as charging rate, if find out a price, with the price of searching as charging rate.

Step 210: general AS receives this response message, sends confirmation to CSCF;

Step 211:CSCF receives this confirmation, according to the calling number in call request and called number, sets up session channel between calling subscriber and called subscriber;

particularly, after CSCF confirmation of receipt information, call request is sent to MGCF (Media Gateway Control Function, MGCF), MGCF receives this call request, search the mobile switch that connects the called subscriber according to the called number that carries in this call request, send demand signalling to this mobile switch, this demand signalling carries calling number and called number, this mobile switch is searched the called subscriber according to called number again, this demand signalling is transmitted to the called subscriber, after the called subscriber receives this demand signalling, reply and confirm that signaling is to this mobile switch, this mobile switch confirmation of receipt signaling also is transmitted to MGCF, MGCF receives the concurrent confirmation of sending of this confirmation signaling to CSCF, CSCF confirmation of receipt information also is transmitted to the calling subscriber, the calling subscriber receives this confirmation, so, set up talk channel between calling subscriber and called subscriber.

Wherein, when CSCF sends to MGCF with call request, and the mobile network that MGCF connects supports signalling, thus after MGCF receives call request, call request need to be converted to demand signalling, then send.

Wherein, when after setting up session channel between calling subscriber and called subscriber, the calling subscriber just can and utilize business and the called subscriber that AS provides to converse by this session channel.

Step 212: general AS monitors and timing calling subscriber and called subscriber's conversation, if hang up or time of timing reaches when setting aside some time in the interior conversation of setting aside some time, send charge information to OCS, this charge information carries the ID of calling number, business and the time of timing at least;

Particularly, when the calling subscriber is conversing with the called subscriber, general AS begins the conversation that calling subscriber and called subscriber carry out is monitored and timing, if timing is at interior calling subscriber and/or the called subscriber's kill-call of setting aside some time, or be not hung up and time of timing reaches when setting aside some time in the interior conversation of setting aside some time, send charge information to OCS, this charge information carries the ID of time, calling number and the business of timing.

Step 213:OCS receives this charge information, and the ID of time, calling number and the business of carrying according to this charge information deducts fees;

Particularly, OCS receives this charge information, the ID of the business of carrying according to charge information, carry out wholesale price and obtain charging rate, the Time Calculation of carrying according to charging rate and charge information cost of the phone call, the calling number of carrying according to this charge information and the ID of business, from the corresponding relation of the ID of the calling number of management server stores, business and residue amount, search corresponding residue amount, deduct cost of the phone call from the residue amount of searching, the residue amount that obtains being left is updated to remaining residue amount with the residue amount of searching.

Wherein, if the conversation between calling subscriber and called subscriber is hung up, general AS, CSCF or calling subscriber send notice to OCS, and finish all operations; If the conversation between calling subscriber and called subscriber is not hung up, after OCS deducts fees operation, also continue execution in step 214.

Step 214:OCS is according to the ID of calling number and this business, and setting is set aside some time, and sends response message to general AS, and wherein, this response message is carried and set aside some time, and returns to execution in step 212.

Particularly, the first step, whether the remaining residue amount of judgement is 0, if not, carries out second step, if so, carries out for the 3rd step;

Second step, OCS reset sets aside some time, and sends and to carry the setting aside some time to general AS of setting, returns to execution in step 212;

Wherein, OCS resets that in the process of setting aside some time and step 209, the process of setting aside some time to be set identical, no longer describes in detail at this.

In the 3rd step, OCS sends notice to general AS, receives the accounting request of general AS transmission, and this accounting request is carried ID and the calling number of the business that general AS reselects;

Wherein, after general AS reception notification, reselect a business information that is used for charging according to rule and policy from remaining business information, and send call request to business AS corresponding to the business information of selecting, when the confirmation information that receives this business AS, send accounting request to OCS, detailed process is seen the content of step 204-208, no longer describes in detail at this.

In the 4th step, the ID of the business that OCS reselects according to calling number and general AS resets and sets aside some time, and sends response message to general AS, returns execution in step 212.

in embodiments of the present invention, CSCF is transmitted to general AS with the call request that the calling subscriber sends, general AS obtains the business information of each business that the calling subscriber contracts, select the business information of a business, business AS corresponding to business that selects given in the forwarding conversation request, send again accounting request OCS, OCS receives this accounting request, setting is set aside some time, reply is carried the response message of setting aside some time to general AS, general AS receives response message, conversation between calling subscriber and called subscriber is monitored and timing, if be hung up in the conversation of setting aside some time between interior calling subscriber and/or called subscriber, or the time of timing arrives when setting aside some time, send charge information to OCS, OCS receives this charge information, deduct fees according to this charge information.Selected the business information of business by general AS, business AS corresponding to business that selects given in the forwarding conversation request, so only have a business AS to make operation in network, send an accounting request to OCS, OCS does not need to select business according to the ID of the business of carrying in each accounting request and calling number, take resource and performance consumption thereby saved, reduce service provider's operation cost; In addition, general AS selects the conversation between business information and monitoring calling subscriber and called subscriber, has shared OCS work, thereby has reduced the equipment investment to OCS.
