Method and apparatus for stable call preservation |
摘要 |
A method and apparatus for preserving call-state information on a wireless communication system is provided. The method includes periodically replicating stable call call-state information between a first and second processor via a network connection. The method also includes performing a transient clear to drop transient calls in existence at the time of an outage of an active first RCS application process or processor. The method also includes forming network-based active call facilities paths to a second RCS application instance and transitioning the second RCS application instance to an active state thereby avoiding a service interruption for the stable calls previously handled by the active first RCS application instance.
