The core network architecture of fusion, a platform for realizing complete IP network fusion is provided for fixed network and mobile network, wherein voice and
The call session class business of video is IMS basic services, and builds the important foundation of the multimedia consolidation service of more horn of plenty.
For call session class business, to avoid timely generation ticket during extended telephone conversation from causing charging to lose, it is desirable to network
Possesses the function that generation timing segmentation ticket is provided for extended telephone conversation.In traditional network, the ticket of call session class business
Directly generated by the network element of offer business, talked about by network element according to the timing sliced time spacing value of setting to generate timing segmentation
It is single.And in the ims network, then a kind of new centralized offline charging framework is employed, i.e., call session industry is generated by IMS network elements
It is engaged in relevant charging message and with offline charging interface（Offline Charging Reference Point between an
IMS Network Entity or an AS and CCF, Rf interface）It is sent to offline charging acquisition function（CCF）Unit,
CCF units then collect the charging message of different IMS network element offer and generate ticket.In this new centralized offline charging framework
Under, no longer it is that ticket is directly generated by IMS network elements, therefore for generating the function of timing segmentation ticket for extended telephone conversation,
It is to be undertaken by CCF units.

3）Also a kind of situation is：For the timing sliced time that the generated timing segmentation ticket duration value of guarantee is setting
Spacing value, CCF units, which are taken, accumulates the duration of received charging message, when duration accumulated value is split beyond timing
Time interval value, CCF units then generate the segmentation ticket of the timing sliced time spacing value of a length of setting at one, and remaining
Duration accumulates the duration for being incorporated into next segmentation ticket.This mode, which can solve to require nothing more than, makees the duration of call timing segmentation
Scene, but be not suitable for timing the scene of specific flow information must also be provided while split.
