RELAY DEVICE, WIRELESS TERMINAL DEVICE, COMMUNICATION SYSTEM AND COMMUNICATION METHOD

摘要

A communication system includes a wireless terminal device related to a predetermined service or group, a relay device, a base station device to be connected to the relay device, a gateway device, and a mobile management device. In the relay device included in the communication system, a registration processing unit transmits to the mobile management device, a first registration request signal that requests registration of the relay device, and receives first communication path information indicating a communication path between the relay device and the gateway device. A device determination unit receives from the wireless terminal device, a connection request signal that requests connection, and determines based on the connection request signal whether or not to transfer data related to the wireless terminal device. A data transfer unit transfers the data using the communication path indicated by the first communication path information.
