Method and system for central office access to multiple access controllers for wireless extension

摘要

A method and system is provided for selectively directing calls to wireless units in an integrated wireline and wireless communication system as part of a wireless extension service. When a call is forwarded by a wireline switch, the receiving wireless access manager determines whether the intended wireless subscriber unit is being serviced by a different access manager. If so, the call is automatically transferred using a high speed ATM inter-access manager communication line. Efficiency is therefore increased because the originating wireline switch does not need to set up an interoffice trunk line to accomplish the necessary call routing.
