摘要
A mobile communication system according to the present invention includes the steps of: causing an UE to switch a radio access network in a connection destination from E-UTRAN to UTRAN/GERAN; causing an MME to receive "Delete Bearer Request" to a voice communication packet bearer from an S-GW; and causing the MME to transmit to the S-GW a "Delete Bearer Response" to the "Delete Bearer Request", without giving an instruction to the UE#1 or the E-UTRAN to release the voice communication packet bearer, if a core bearer disconnection flag is set in the received "Delete Bearer Request".
