摘要
A mobile communication system of the present invention comprises: a process wherein a UE switches the connection destination wireless access network from E-UTRAN to UTRAN/GERAN; a process wherein an MME receives, from an S-GW, a Delete Bearer Request to an audio communication packet bearer; and a process wherein the MME, when a core-bearer cut-off flag is set within the received Delete Bearer Request, transmits, to the S-GW, a Delete Bearer Response in response to the Delete Bearer Request, without giving instructions, to UE #1 or the E-UTRAN, to release the audio communication packet bearer.
