Problems solved by technology

[0017] 4. There is no necessary synchronization between receiving billing events and creating CDRs
[0019] 6. All charging events used to construct a CDR must originate from the same NE
[0045] Now if you only want the calling S-CSCF or a certain AS to charge the user service, other network elements do not need to charge the user service. Under the current charging mechanism, this requirement cannot be realized

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 .

[0138] S70...

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 ...

Embodiment 3

[0152] Such as Picture 9 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, but according to the local charging policy of S-CSCF / AS, charging is required Processing, the implementation process of applying the above invention includes the following steps:

[0153] S902. The S-CSCF / AS receives the SIP service request message, and the request message carries a special charging identifier.

[0154] S904, a) The S-CSCF / AS recognizes the special charging identifier in the SIP service request; b) The S-CSCF / AS determines that it needs to send a charging request message to the charging entity according to the configured local charging policy.

[0155] S906: The S-CSCF / AS sends a charging authorization request message to the charging entity, and inserts a special charging identifier in the charging authorization request message.

[0156] S908, ...

Abstract

The invention is concerned with the IMS network charging system and the method, includes: step S502, the charging entity adds the special charging marking to the charging respond sending to the net element according to the charging strategy when the charging request is without indication that need not process the special charging marking of the charging process in the charging request receiving from the net element; step S504, when the special charging marking exists in the charging response, the net element adds the special charging marking to the front net element operation response or the following net element operation request; step S506, when the special charging marking exists, the following net elements and the front net element according to the special charging marking and charging strategy confirms whether or not sends the charging request to the charging entity, and adds the special charging marking to the following net element operation request or the front net element operation respond; step S508, the charging entity recognizes the existing special charging marking, confirms whether or not processes charging process according to the special charging marking and charging strategy.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to an IMS network charging system and method. Background technique [0002] IMS is a subsystem superimposed on the existing packet domain in the WCDMA network added in the 3GPP R5 stage. The packet domain is used as the bearer channel for the upper layer control signaling and media transmission. The SIP protocol is introduced as the service control protocol. It is simple to use SIP , Easy to expand, and convenient media combination. By separating service control and bearer control, it provides rich multimedia services; the main functional entities in IMS include the call control entity CSCF that controls user registration, session control and other functions, and the centralized management of user subscriptions The data home user server HSS, the application server AS that provides various business logic control functions, the charging collection function CCF for offline charging and ...
