Embodiment 1
[0134] Such as Figure 7 As shown, the network element in the IMS network receives a SIP service request without a special charging identifier, and the service charging policy on the charging entity is configured so that no charging processing is required in subsequent network elements, and the implementation of the above invention is applied The process includes the following steps:
[0135] S702. The S-CSCF / AS receives the SIP service request message, and the request message does not carry a special charging identifier.
[0136] S704: The S-CSCF / AS sends a charging authorization request message to the charging entity.
[0137] S706, a) The charging entity performs charging authorization processing; b) The charging entity decides that it needs to insert a special charging identifier in the response message according to the service charging policy or user subscription information to identify that subsequent network elements do not need to perform charging processing .

Embodiment 2
[0145] Such as Figure 8 As shown, the network element in the IMS network receives a SIP service request with a special charging identifier, and its identifier is that subsequent network elements do not need to be charged, nor do they need to be calculated according to the local charging policy of the S-CSCF / AS. Fee processing, the implementation process of applying the above invention includes the following steps:
[0146] S802. The S-CSCF / AS receives the SIP service request message, and the request message carries a special charging identifier.
[0147] S804, a) The S-CSCF / AS recognizes the special charging identifier in the SIP service request; b) The S-CSCF / AS determines that it does not need to send a charging request message to the charging entity according to the configured local charging policy.
[0148] S806. After the S-CSCF / AS executes the corresponding SIP service processing, the SIP service request message is forwarded, and the SIP service request message carries the ...
