Method and apparatus for providing different terminating call treatments based on service area
First Claim
1. A method for rerouting an incoming call intended for a mobile station to an alternative terminal, said method comprising the steps of:
- receiving a first signal requesting routing instruction for said incoming call, said first signal received within a mobile switching center/visitor location register (MSC/VLR) currently serving said mobile station;
determining at said MSC/VLR a particular service area where said mobile station is currently located;
determining at said MSC/VLR whether a different routing treatment should be applied for said particular service area; and
retrieving a routing address assigned to said particular service area, wherein said routing address represents said alternative terminal; and
transmitting a second signal containing said routing address by said MSC/VLR instructing said incoming call to be routed to said alternative terminal.

Abstract
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.

8. A method for rerouting an incoming call intended for a mobile station located within a particular service area, wherein said particular service area is served by a mobile switching node and all incoming calls terminating within said particular service area need to be rerouted to an alternative terminal, said method comprising the steps of:
-
receiving a first signal requesting routing instruction associated with said incoming call by said mobile switching node; determining at said mobile switching node whether said mobile station is within said particular service area; and in response to an affirmative determination; determining a routine address assigned to said service area wherein said routing address represents said alternative terminal; and transmitting a second signal containing said routine address by said mobile switching node wherein said routing address instructs said incoming call to be routed to said alternative terminal. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A mobile switching center (MSC) for rerouting an incoming call intended for a particular mobile station to an alternative terminal, said MSC comprising:
-
means for receiving a first signal requesting routing instruction for delivering said incoming call to said mobile station; means for determining a particular service area said mobile station is currently located; means for determining whether a different call treatment should be applied for said particular service area; and means responsive to an affirmative determination for retrieving a routing address assigned to said particular service area, wherein said routing address represents said alternative terminal and for transmitting a second signal containing said routing address, said routing address instructing said incoming call to be routed to said alternative terminal. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A mobile telecommunications system comprising:
-
a telecommunications node serving a plurality of service areas, a certain one of said plurality of service areas subject to an alternative routing instruction for terminating incoming calls; an alternative terminal associated with a routing address, said routing address further assigned to said certain one of said plurality of service areas; means for determining that an incoming call is to be terminated to a mobile station currently located within said certain one of said plurality of service areas; and means associated with said telecommunications node for routing said incoming call using said routing address to said alternative terminal for handling instead of to said mobile station. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)
