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.
