Method and device for carrying out security procedures involving mobile stations in hybrid cellular telecommunication systems
First Claim
1. A method for externally triggering a security procedure for performance by a cellular network, where a hybrid cellular telecommunication system communicates with a mobile station and the hybrid cellular telecommunication system communicates with the cellular network, the method comprising:
- sending a security procedure triggering message to the cellular network, after a decision to trigger the security procedure of the cellular network is made by an external element functionally connected to the cellular network;
wherein the hybrid cellular telecommunication system lacks the capacity to perform the security procedure for any mobile station, data related to the security procedure is transferred between the cellular network and the mobile station in both directions via the hybrid cellular telecommunication system, and the mobile station, the hybrid cellular telecommunication system and the cellular network are separate entities.

Abstract
A method (300) for carrying out a security procedure with a mobile station, where a hybrid cellular telecommunication system communicates with a mobile station (301) and the hybrid cellular telecommunication system communicates with a cellular network (308). The method is characterized in that the cellular network carries out the security procedure with the mobile station, the data related to the security procedure is transferred between the cellular network and the mobile station via the hybrid cellular telecommunication system, and the decision of triggering the security procedure of the cellular network is made outside the cellular network (309). The invention also relates to a network element (510) in the hybrid cellular telecommunication system that triggers the security procedure and to a network element (500) in the cellular network that carries out the security procedure after receiving a triggering signal.
