| Abstract;On conventional connection method of mobile communication, frequency resources were fixedly distributed to every users, and their terminals were continued to occupy every channels allocated from beginning call to ending one. Therefore, both voice and data calls had low application ratio of the channels by means of non-transmission sections on their informations. In this paper, was proposed a 'user relay scheme' for every terminals under direct communication with a base station to relay data communication services with low requirements for real-timing such as dialugue data communication, short message communication like electronic mail, and so on, by using non-transmission sections of the terminals in mobile communication. As a result of simulation, it was found to enable to widely improve features such as call loss ratio, through-put, and so on under delay time suitable for practice, to prove effectiveness based on the proposed method such as improvement of channel application efficiency, increase of users' capacities accompanied with it, and so on. |
