Local control enhancement in a telecommunications systems
First Claim
1. In a mobile telecommunications system, a method of supporting local control functionality independent of mobile station roaming status, said method comprising the steps of:
- receiving in said system a registration message transmitted from a mobile station, said registration message comprising at least one identification code for determining local control features supported by said mobile station, wherein said local control features are customizations of air interfaces to provide special local services within said system;
determining from said registration message whether said mobile station supports one or more of said local control features also supported by said system; and
responsive to the determination;
transmitting a first type registration confirmation message to said mobile station if said local control features are not supported; and
transmitting a second type registration confirmation message to said mobile station if said local control features are supported.

Abstract
A method and system for providing support of local control functionality in a mobile telecommunications system independently of mobile station roaming status is provided. In the invention, upon receiving a registration access message a visited system accesses a database and determines whether the registering mobile station supports local control features supported by the system. If the mobile station and system support common local control features the system returns a local control registration confirmation message in place of the normal system registration confirmation message. The local control registration confirmation message confirms registration and also serves as an indication to the mobile station that the mobile station and system support common local control features. The mobile station and system may now function accordingly to allow use of the common local control features.
