DETECTION OF BEARER LOSS IN AN IP-BASED MULTIMEDIA SESSION

摘要

The present invention provides a method for detecting bearer loss in an IP-based multimedia session. A multimedia session is initiated by an access terminal. A Policy and Charging Rules Function (PCRF) communicates the Session setup information and the bearer characteristics to a Signaling Gateway (SGW). The SGW uses this information to adjust the dormancy timers on the originating side so that the originating access link remains active during the call setup.
