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. |
