ABSTRACT:
A method and system for changing subscriber service features in a radio telecommunications network is disclosed. The method begins by a subscriber originating a call from a telephone located in a telecommunications network to a roamer port located within a Mobile Switching Center (MSC) which may be located inside or outside the subscriber's home coverage area. The MSC sends a dial tone to the telephone. Next, the subscriber sends a feature code and Mobile Identification Number (MIN) through the telephone to the MSC requesting a service feature change. The MSC recognizes and verifies the feature code as a valid code. The MSC also associates a service feature change corresponding to the feature code and associates the MIN with a HLR. The MSC sends a feature request invoke message to the associated HLR requesting a service feature change. Then, the HLR implements the service feature change in the HLR. If the roamer port coverage encompasses more than a single MSC, and the subscriber is located in an MSC that does not include the roamer port, the HLR updates the subscriber's categories in the MSC in which the subscriber is currently registered.
