Abstract: The resource release system minimizes the time that the Mobile Switching Centers in a call initiation process commit resources after the call is terminated. This is accomplished by propagating a Call Release message through the cellular network from the Originating Mobile Switching Center to the Serving Mobile Switching Center as soon as the termination of the call initiation process is determined by the Originating Mobile Switching Center. As the Call Release message is propagated through the cellular network, each Mobile Switching Center that receives the message immediately propagates the message along the path through the cellular network toward the Serving Mobile Switching Center and releases the network resources that have been reserved for this call initiation process, thereby minimizing the amount of time network resources are maintained in a held state for this call initiation.

Abstract: The global authentication continuity feature uses a new ANSI-41 message, the AUTHENTICATION GLOBAL DATA message, to convey global authentication information to the Mobile Switching Center that has just become the serving Mobile Switching Center due to a handoff. This provides continuity of the global authentication process, even though the mobile subscriber wireless communication device hands-off to another Mobile Switching Center. The information that is passed forward from the Visited Location Register of the previous serving Mobile Switching Center to the new serving Mobile Switching Center could be RANDShared Secret Data to perform a Shared Secret Data update, RANDU/AUTH to perform an Unique Challenge, Voice Privacy Masks, and Signal Encryption Keys.
