Abstract
A communication system for transmitting data of a first mobile station to a second mobile station includes a base station and a relay device. The base station is utilized for configuring an uplink and a downlink of the data to correspond to a first connection ID and a second connection ID respectively and for transmitting a traffic encryption key to the first and second mobile stations so that the first and second mobile stations share the traffic encryption key. The relay device is coupled to the base station and the first and second mobile stations via wireless communication, and utilized for receiving the data encrypted by the traffic encryption key and transferring the data of the first mobile station to the second mobile station according to the first and second connection IDs without going via the base station.
