Abstract

For control of connections in cellular telecommunication systems, particularly setting up and releasing of connections, it is checked whether a radio resource control (RRC) connection is already active during setting up of anew mobility management (MM) connection. If an RRC connection is already active, explicit signaling is used. Otherwise, RRC level events can be used to implicitly control MM level events. During releasing of MM connections, it is checked if another MM protocol uses RRC connections, and if that is the case, the releasing of MM connections is signaled explicitly.
