A circuit mobility management entity (CMM) is intended a mobile network adapted for transferring data in a dual transfer mode to and from mobile stations. The CMM is arranged, when it has established a circuit-switched (CS) connection between a mobile station and the mobile network and when it receives from a radio resource entity (RR) of the mobile network, a message informing that the CS procedure corresponding to this CS connection is ended, to determine if a GPRS Tunnelling Transport Protocol (GTTP) procedure is running for a packet-switched (PS) signalling procedure which concerns the mobile station, then either i) require release of the CS connection near the RR entity if the GTTP procedure is ended, or ii) maintain the CS connection as long as the GTTP procedure is running, and require release of the CS connection near the RR entity when the GTTP procedure is ended.
A process for transferring data in a dual transfer mode between a mobile communication equipment and a mobile communication network, said process comprising carrying out a packet-switched signalling procedure by a GPRS Tunnelling Transport Protocol (GTTP) protocol through a circuit-switched connection established between said mobile communication network and said mobile communication equipment, in order to establish a packet-switched connection between them, wherein, when said circuit-switched procedure corresponding to said circuit-switched connection is ended, to determine if a GTTP procedure is running for said packet-switched signalling procedure, then i) either to release said circuit-switched connection if said GTTP procedure is ended, ii) or to maintain said circuit-switched connection as long as said GTTP procedure is running, and to release said circuit-switched connection when said GTTP procedure is ended.
