MOBILE COMMUNICATION SYSTEM, DATA COMMUNICATION METHOD, GATEWAY DEVICE, AND BASE STATION

摘要

The purpose of the present invention is to provide a mobile communication system and a data communication method whereby the resource load can be reduced in a mobile phone system. This mobile communication system is provided with an SGW (40) for transfer of user data to and from an eNodeB (20), and a PGW (50) for transfer of user data to and from an external network. The SGW (40) and the PGW (50) are configured such that small volumes of data sent and received autonomously from a terminal device through the eNodeB (20) is transferred between the SGW (40) and the PGW (50) by using a communication resource for the transfer of control signals, rather than a communication resource for the transfer of user data.
