Title: Mobile station
Inventor: AOKI MASATOSHI
IPC: H04B7/26
Filed: 2002-11-07
Abstract: <P>PROBLEM TO BE SOLVED: To distribute a load applied to all mobile stations performing communication by switching mobile stations (clock master) that emit radio waves for synchronization at prescribed timing in the case of performing inter-mobile station communication.  <P>SOLUTION: The clock master performs a switching request to a mobile station in a slave mode (S52) when its own station satisfies a condition of master switching request transmission, e.g. a decrease in capability as a clock master or the like (S51). A mobile station in a slave mode which satisfies a condition of master switching response transmission, e.g. a mobile station whose capability as a clock master is maximum or the like responds to the switching request (S56 and S57). Thus, the current clock master becomes a mobile station of a slave mode (S54), and the mobile station in a slave mode becomes a new clock master at the same time (S58).  <P>COPYRIGHT: (C)2003,JPO
