The present invention provides a method and an apparatus for resuming the evaluation of initial Filter Criteria (iFC) at a specific point. Two new parameters are defined for inclusion in the service logic of application servers and serving Call Session Control Function (S-CSCF) servers. The first parameter, an iFC index parameter, is a number which indicates an index to a current specific position in the iFC evaluation. The S-CSCF may insert the iFC index parameter into route headers of SIP messages that originate from the S-CSCF to the application servers. The second parameter, an iFC resume parameter, is based on the iFC index parameter or another number along with an original dialog identifier, which the application servers may insert into route headers of SIP messages that originate from the application servers to the S-CSCF to indicate a desire to resume operations at the specific position in the iFC evaluation.

Mechanism to resume filter criteria at a specific point

IMS networks and associated methods are disclosed that provide charging for CAMEL services provided in the IMS network. If a CAMEL service is provided by an application server for a session in an IMS network, then the application server generates CAMEL charging data for the service provided and also generates a charging message, such as a Diameter ACR message. The application server includes the CAMEL charging data in the charging message and transmits the charging message to a charging collector system. The charging collector system generates a CDR for the session, and maps the CAMEL charging data from the charging message to the CDR. The charging collector system then transmits the CDR to a billing system. The billing system may then charge for the CAMEL service provided in the IMS network.

Camel service charging in IMS networks

A method and system for forwarding calls in telecommunication networks are provided. More particularly, control of late call forwarding logic and routing is placed at the home network Gateway MSC and HLR, thus removing the home network service provider's dependency on the visited network capabilities.
