IPC: H04W88/02
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a mobile station that does not reduce the frequency utilizing efficiency while conducting non-interruptive hand-over. SOLUTION: When a mobile station MS is resident in an area of a cell #1, its beam radiation is directed in a direction of a wireless base station BS1 to use a communication channel #1 for wireless communication. When the mobile station MS moves to a border area between cells #1 and #2, the mobile station MS sets up a link to wireless base station BS2 with an assigned communication channel #2 for transmission/reception. In this case, the mobile station MS simultaneously holds two communication channels with the same two contents. When the mobile station MS reaches the border between the cells #1 and #2., the communication channel is switched from the #1 to the #2 to interrupt the wireless link with the wireless base station BS1 and leaves only the wireless link with the BS2.  In the soft hand-over above, since beams which are directed to the wireless base stations B1, B2 have a sufficient angle difference, the same frequency can be used.
