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 access to a business information, then general AS directly selects this business information, if general AS gets access to a plurality of business information, then 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 " selecting business information by professional priority ", promptly general AS according to each professional priority, selects the business information of the high business of priority according to this rule and policy.

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

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

Wherein, store the ID of calling number, business and the corresponding relation of residue amount in the 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 calling number of management server stores, professional ID and the corresponding relation that remains amount, if the residue amount of searching is not 0, then execution in step 206.

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

Step 206: general AS sends to corresponding service AS according to the address of the professional AS of the business information of selecting that is used for chargeing 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 and give 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 should determine and to provide professional for this calling subscriber by business AS, then send and be notified to general AS, after then general AS receives this notice, if also there is remaining business information, then from remaining business information, select a business information that is used to charge, begin operation from step 305 again, otherwise, end operation.

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

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

Step 209:OCS receives this charging request, and according to calling number in the request of chargeing and professional ID, 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 charging request, ID according to the business in this charging request carries out wholesale price, obtain charging rate, according to the calling number and the professional ID that carry in this charging request, from the calling number of management server stores, professional ID and the corresponding relation that remains amount, search corresponding 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, then calculate and set aside some time according to residue amount and charging rate; If do not surpass, the time that will set aside some time and be set to preset then, send and 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, existingly at present multiplely carry out the method for wholesale price according to the ID of business, for example, the professional ID and the corresponding relation of price can be set in OCS in advance, wherein, each business can one or more prices of correspondence.

Therefore, OCS carries out the operation of wholesale price according to the ID of the business that the request of chargeing is carried, be specially: OCS receives this charging request, according to the ID of the business of carrying in this charging request, from the corresponding relation of the ID of business and price, search the price of correspondence, if find out a plurality of prices, select a price as charging rate according to predetermined strategy, if find out a price, then 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 calling number in the call request and called number, sets up session channel between calling subscriber and called subscriber;
