IMPROVED PROCESS FOR TRANSFERRING DATA IN A DUAL TRANSFER MODE BETWEEN A MOBILE NETWORK AND MOBILE STATIONS, AND CORRESPONDING CIRCUIT MOBILITY MANAGEMENT ENTITY

摘要

A circuit mobility management entity (CMM) is intended for a mobile network adapted for transferring data in a dual transfer mode to and from mobile stations. This circuit mobility management entity (CMM) is arranged, when it has established a 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 GTTP procedure is running for a PS signalling procedure which concerns the mobile station, then i) either to require the releasing of the CS connection near the RR entity if the GTTP procedure is ended, ii) or to maintain the CS connection as long as the GTTP procedure is running, and to require the releasing of the CS connection near the RR entity when this GTTP procedure is ended.
