<p><P>PROBLEM TO BE SOLVED: To provide a radio communications device capable of handing over a call established by one network to another network without renouncing the call. <P>SOLUTION: A radio communications device is arranged to communicate time divided signals over first and second time discontinuous systems having first and second frame structures respectively. In such a radio communications device, a multi-mode block 120 switches between communicating signals 60 over a first network 40 during time periods of the first frame structure and communicating signals 70 over a second network 50 during time periods of the second frame structure. Hence over a given period of time, the device simultaneously communicates time divided signals over the first and second networks. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
