Abstract

Methods, systems, and computer program products for using an LRN based query and response mechanism (e.g., a switching office number portability processing system) to route calls to IP multimedia subsystem (IMS) subscribers are disclosed. According to one method, an LRN based response message including a communications service subscriber identifier is received. An IMS gateway LRN associated with the communications service subscriber identifier may be determined. The IMS gateway LRN associated with the communications service subscriber identifier may be inserted into the LRN based response message and routing the message.

Description

[0001] related application [0002] This application claims the benefit of U.S. Provisional Patent Application Serial No. 60 / 902,543, filed February 21, 2007, and U.S. Patent Application Serial No. 11 / 731,772, filed March 30, 2007, both applications Each of the applications in is hereby incorporated by reference in its entirety. technical field [0003] The subject matter described herein relates to modifying location routing number response messages (eg, number portability response messages) and network node offloading. More specifically, the subject matter described herein relates to routing calls to users of an IP Multimedia Subsystem (IMS) using a location routing number based query and response mechanism. Background technique [0004] Local Number Portability (LNP) allows telephony service subscribers to retain their same directory number when they change service locations and / or service providers. The Telecommunications Act 1996 introduced requirements for telephone ...
