System for controlled provisioning of telecommunications services

In a wireless communications network comprising a home register that maintains a profile for a mobile station, and a serving system that maintains a profile for the mobile station when the mobile station is located within a service area associated with the serving system, wherein the home register provides the serving system with a profile for the mobile station in response to a change in the profile maintained by the home register, a method for imposing in the serving system a designated service set for the mobile station by monitoring and modifying information delivered between the home register and the serving system, the method comprising:

• detecting, at a message mediator, a message sent by the home register, the message defining a profile for the mobile station;
• modifying the profile so as to generate a modified message defining a modified profile comprising the designated service set for the mobile station;
• and
• forwarding the modified message to the serving system,
• wherein the message mediator includes a data storage medium, a processor, and logic stored in the data storage medium and arranged to be executed by the processor to carry out the detecting, modifying, and forwarding functions,
• whereby the serving system is arranged to receive the modified profile for the mobile station and to responsively maintain and employ the modified profile comprising the designated service set for the mobile station.
