CALL DELIVERY TO AN IMS NETWORK FOR A MOBILE DIRECTORY NUMBER HOMED IN A 2G WIRELESS NETWORK |
摘要 |
A system and method to provide call delivery to an Internet Protocol Multimedia Subsystem (IMS) network for a Mobile Directory Number (MDN) homed in a second generation (2G) wireless network, without requiring Wireless Intelligent Network (WIN) operations and associated Mobile Switching Center emulation (MSCe) translations for routing the call request. A Home Location Register (HLR) determines whether the subscriber has subscribed to the IMS services. The HLR-based subscriber profile is enhanced with new IMS-related subscriber information. Enhanced American National Standards Institute-41 (ANSI-41) Mobile Application Part (MAP) operations and a new ANSI-41 parameter allow the MSCe to re-route the call origination request from a Public Switched Telephone Network (PSTN) to an entry point for the IMS network based upon the new IMS-related subscriber information received from the HLR. A Domain Name Server (DNS) supports routing-related traffic distribution.
