Abstract
In a communications system, the subscriber data in a home network of a subscriber is provided with a subscriber ciphering profile, which indicates whether an unciphered call, session or data packet is to be rejected, accepted or handled in some other manner. A serving network checks the subscriber ciphering profile in one or more of the following cases: 1) for each setup of an unciphered call or connection, 2) for each unciphered packet switched data transmission session, or 3) for each packet data transmission originating from subscriber equipment, and rejects or accepts the unciphered call, connection, session, or data packet, respectively, according to the subscriber ciphering profile. As a result, unciphered calls, sessions, or packet data transmissions will be reliably rejected.
