| Abstract(in English) | The Quasi-Zenith Satellite System (QZSS) is expected to provide a high accurate positioning service and allows two-way communication which includes terminal location and short messages. For realizing the random access control scheme of the QZSS short message communication, we have proposed Flag Method and reservation channel (R-Ch) scheme. However, there is unfairness between the number of collisions and the time required to accommodate a mobile terminal. In this paper, we propose an efficient random access control scheme to improve the fairness among the mobile terminals. The proposed scheme can reduce the accommodation time to achieve the complementary cumulative distribution function (CCDF) of $10^{-5}$ by about 26$%$ at the expense of about 3$%$ of the average accommodation time. |
