Title:
GATEWAY DEVICE, FEMTOCELL-USE BASE STATION, COMMUNICATION SYSTEM, COMMUNICATION METHOD, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2015/186331
Kind Code:
A1
Abstract:
When a mobile terminal currently performing a telephone communication or currently initiating a call by use of a VoLTE function has moved from an LTE network to 3G femto-network, a GW (100) is connected to an MME (200) placed in an access network in the LTE network and to an FAP (300) the communication area of which is an IMS-femtocell area so as to take over the telephone communication or the initiation of the call. When the mobile terminal currently performing the telephone communication or currently initiating the call has moved from the communication area of the LTE network to the IMS-femtocell area, the call processing of the mobile terminal is caused to be taken over from the MME (200) to the FAP (300).
