The present invention relates to proxy handling messages of a mobile user entity in a mobile communications network comprising a first switching control node supporting Circuit Switched Fallback (CSFB) functionality and a second switching control node not supporting the CSFB functionality. The proxy comprises an interface configured to receive a message containing Circuit Switched Fallback Mobile Originated (CSMO) call indicator or a Circuit Switched Fallback Mobile Terminated (CSMT) call indicator from the mobile user entity. A proxy control unit is configured: to determine whether the CSMO call indicator or the CSMT call indicator is set in the received message, initiate routing of the received message to the first switching control node if the CSMO call indicator or the CSMT call indicator is set, and initiate routing of the received message to the second switching control node if neither the CSMO call indicator nor the CSMT call indicator is set. |
