ABSTRACT:
A system deactivates an established communication channel between a user station and an access point. The system provides a service to the user station. The system transfers user data stored in a database entity to a serving controller connected between the user station and the access point. The system defines at the serving controller that the user station is not permitted to access the service, and allows for deactivation of the established communication channel based on the transferred user data.
