MOBILE COMMUNICATION SYSTEM, RADIO COMMUNICATION APPARATUS, NETWORK APPARATUS, AND RADIO TERMINAL
First Claim
1. A mobile communication system supporting direct terminal-to-terminal communication, the mobile communication system comprising:
- a user terminal configured to receive a first control signal via first connection with a base station, and to perform the direct terminal-to-terminal communication with another user terminal based on the first control signal,a network apparatus, included in a cellular communication network, configured to change a proportion of first radio resources to uplink radio resources assigned to the mobile communication system,wherein the user terminal includes;
a network interface configured to receive user data addressed to the another user terminal, via second connection different from the first connection; and
a controller configured to perform a processing of relaying the user data to the another radio terminal through the direct terminal-to-terminal communication,wherein the first radio resources assignable to the direct terminal-to-terminal communication are part of the uplink radio resources.

Abstract
A mobile communication system supports D2D communication being direct terminal-to-terminal communication. The mobile communication system comprises: UE 100-1 that receives a first control signal from a cellular communication network, and performs the D2D communication with UE 100-2 based on the first control signal. The UE 100-1 connects to cable communication network 40 and receives downlink user data addressed to the UE 100-2 from the cable communication network 40. The UE 100-1 performs D2D data relay of transmitting the downlink user data received from the cable communication network 40, to the UE 100-2 through the D2D communication.
