Through the invention described above USI charging method first embodiment, the USI system can generate user data record UDR in the calling service process, and UDR is reported aaa server, obeys through AAA and accomplishes the professional charging to USI.

Charging described in the embodiment of the invention has two kinds of situation, and a kind of is offline charging (off-lineAccounting), and a kind of is online charging (online Accounting), the detailed description that will combine accompanying drawing that both of these case is carried out below.

Referring to shown in Figure 3, be the schematic flow sheet of professional off-line accounting method second embodiment of USI, this method is applicable to that the user has the situation of USI ability, it comprises the steps:

Step 301, ASP system send business request information to the USI system.

Usually there is multiple situation can trigger the ASP system and sends business request information to the USI system; For example the ASP system receives that an ASP service request from user, ASP system are received from the service request of other ASP system, ASP system and detects and need take place or the like to the incident of USI system request business operation; They all are application layer network internal incidents, this are not done deep description in an embodiment of the present invention.

Comprise in the above-mentioned business request information: the user's of ASP sign (ASP ID), the USI ability that is called USI sign (USI ID), business information (Service Info), ASP charging identifier.

Wherein, ASP ID can be that Applications Service Provider is configured when being deployed in the ASP network, the usually corresponding ASP ID of ASP network.

The ASP charging identifier is generated by the ASP system, and it can be ASP ID, service identification (ServiceID) or type of service (Service Type) etc.

User's USI ID can be the ASP system through before and the user between application layer obtain in mutual, also can be that the ASP system obtains according to the application layer service control logic.The sign that the ASP system obtains in mutual with user's application layer; Or the sign of obtaining according to application layer service control logic user's ID normally, this ID can be a kind of in user's application layer sign (App UserID), user's USI sign (USI ID), user's IP address or user's the NSP sign (NAI).If the ID that the ASP system obtains is user's USI ID, then the ASP system does not need to handle again; If the ID that the ASP system obtains is other signs except that USI ID; Then need to find the corresponding USI ID of this user according to the sign of obtaining; Being the ASP system inquires about according to being identified in the customer data base of getting access to; If found satisfactory user record, then from user record, extract the corresponding USI ID of this user.

After business request information is received by step 302, USI system, confirm to authorize this USI to call according to the USI strategy, as authorize success, then send the USI request message to having the professional network element of opening function.

After business request information is received by the USI system, confirm to authorize this USI to call according to the USI strategy, then the USI system generates corresponding with it USI charging identifier according to the ASP charging identifier, and safeguards the incidence relation of the two.

Because USI ID has only USI system or ASP system to discern, and other network entities in the WIMAX network normally can not be discerned, so the USI system also need be mapped as user's USI ID user's NAI or IP address.Generally; The USI system can get access to user's USI context and be kept at this locality from AAA when user-network access; Comprising user's USI ID corresponding NAI or IP address, so the USI system can inquire user's NAI or IP address according to user's USI ID in the information that preserve this locality; If the USI system is local not about the information of this USI ID, the then NAI or the IP address of USI system inquiring user in the aaa server.
