TARGET BASE STATION - BASED MEDIA GATEWAY SELECTION IN A DISTRIBUTED MOBILE SWITCHING CENTER ENVIRONMENT

摘要

A temporary directory number is assigned (225, 240, 250) in a distributed mobile switching center environment in response to receiving (205) a request for routing information at a signaling node (110) in a telecommunication network (100). The request for routing information is associated with a call to a mobile station (140), and the signaling node handles signaling in a geographical area for multiple geographically distributed switching nodes (115(1), 1115(2)). A location of the mobile station is determined (210), and a pool of directory numbers (175) associated with a particular node is identified (215). The particular node is associated with a portion of the geographical area that includes the location. A directory number from the pool of directory numbers is assigned for use in connecting (265) the call to the mobile station.
