MOBILE COMMUNICATION SYSTEM, MOBILE STATION APPARATUS AND RE-CONNECTION METHOD

摘要

It is possible to complete a re-connection in a short time and prevent instantaneous interruption of communication by including a plurality of base station apparatuses and a mobile station apparatus; the mobile station apparatus comprising: a delay difference detecting unit that detects a difference in reception timing between a signal from the base station apparatus with which the mobile station apparatus currently communicates and a signal from the base station apparatus that is a re-connection destination candidate; a transmission timing calculating unit that calculates, based on the difference in reception timing, a transmission timing to the base station apparatus that is the re-connection destination candidate; and a re-connection processing unit that, having detected a disconnection of the communication with the base station apparatus with which the mobile station apparatus currently communicates, uses the transmission timing, which has been calculated in advance, to start a communication with the base station apparatus that is the re-connection destination candidate decided in advance.
