Abstract: In a method for managing access by a user device to multimedia services delivered by a communication system, the user device accesses the multimedia services through a Radio Access Technology (RAT). An information element sent to the user device from the communication system includes restriction information that indicates the types of RAT that the user device may use to access the multimedia services. The restriction information also includes the types of RAT that the user device cannot use to access the multimedia services. The information element also includes additional restriction information indicating the multimedia services that can be accessed by the user device, and the multimedia services that cannot be accessed by the user device. The additional restriction information is based on subscription information for the user device.
