Abstract

In the context of facilitating a circuit switched to packet switched handover of a call in a cellular communication system (101) a first node (611 711 800) (e.g. packet switched target node) generates a security context for a client (601 701) whose call is being handed over. This involves the first node (611 711 800) receiving (501) at least one cryptographic key from a second node (607 707) (e.g. a circuit switched node supporting the existing connection) and receiving (503) identities of security algorithms supported by the client (601 701) from a third node (609 709) (e.g. a packet switched node supporting the existing connection); The first node (611 711 800) uses (505) the at least one cryptographic key and the identities to generate the security context for the client (601 701).
