Connection attempt management technique in a circuit switching withdrawal situation

摘要

Procedure for managing mobile termination connection attempts for a mobile terminal (450) for which a change of an association from a first routing node (420) to a second routing node (430) is accompanied by a switching switching of circuits, or CS, in which the procedure comprises the following steps performed by the first routing node (420): receiving a first attempt to connect the mobile termination to the mobile terminal (450); in response to the reception of the first attempted mobile termination connection, determining that the mobile terminal (450) cannot be reached by the first routing node (420); determining an identity of the second routing node (430), in which the identity of the second routing node (430) is determined based on the information received by the first routing node (420) from the second node (430) of routing; transmit, to the second routing node (430), a second attempt at a mobile termination connection for a CS connection to the mobile terminal (450).
