Abstract:
It is presented a method for assisting access to access protected services in a cellular multimedia delivery system. The method is performed in a wireless device and comprises the steps of: obtaining a set of one or more service identifiers, each service identifier being associated with a service; for each service identified by one of the service identifiers, determining if the service is access protected by reading a configuration associated with the service, independent of any delivery method associated with the service; and transmitting, to a key manager server, a request for service keys for all services which have been determined to be access protected. A corresponding wireless device, compute program and computer program product are also presented.
