  • Patent number: 6594492
    Abstract: In the context of a completed inter-exchange handoff of a mobile station communication, an anchor exchange may request certain call related information from a currently serving exchange. This request is made through use of an inter-exchange information request message issued from the anchor exchange and sent (perhaps through one or more tandem exchanges) to the serving exchange. Responsive thereto, the serving exchange processes the request, obtains the requested call related information, and returns the requested information in an inter-exchange information request return result message. The information request message may comprise a newly defined ANSI-41 message, a vendor proprietary extension to the ANSI-41 message set, or an enhancement to an existing ANSI-41 message.
