US 2003/0152232 A1 · Control of unciphered user traffic

Abstract

In a communications system, the subscriber data in a home network (HLR) of a subscriber (UE) 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 (MSC/VLR, SGSN,UTRAN) 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 if the network operator or the user sets the subscriber ciphering profile accordingly.

Dependent claims

A method of controlling unciphered traffic in a wireless communications system comprising user equipment which is able to communicate with a serving network by means of ciphered and unciphered connections, characterized by the steps of

maintaining a subscriber ciphering profile for at least one subscriber equipment in a home subscriber data base of said at least one subscriber equipment, said subscriber ciphering profile defining how unciphered user traffic should be handled,
the serving network checking the subscriber ciphering profile in an unciphered transaction and the functions according to the subscriber ciphering profile.
