A method and apparatus for providing different terminating call treatments based on service area

摘要

A routing address representing an alternative terminal is assigned to a particular service area. Such a service area comprises a Local Access and Transport Area (LATA), Mobile Switching Center (MSC) area, Location Area, and Cell Area. Whenever an incoming call is received towards a mobile station currently located within the particular service area, instead of transmitting a routing address representing the mobile station, the serving mobile switching center (MSC) transmits a signal containing the routing address representing the alternative terminal. Instead of routing the call to the intended mobile station, the gateway mobile switching center (GMSC) utilizes the received routing address and reroutes the incoming call to the alternative terminal. By rerouting all incoming calls towards the alternative terminal in case of an emergency, all available access channels are reserved for making outgoing calls by the mobile subscribers located within the emergency service area.
