Low-power wireless system for telephone services. |
摘要 |
A small telephone system provides telecommunications services for personal wireless telephone sets over an area which is divided into service cells. Each of the cells is defined by reception characteristics of a plurality of radio base stations within the cell. During a call progress, if the wireless telephone set is mobile, a radio link with the set is handed off from one cell to another as the wireless telephone set moves along. The telephone system includes a service controller and a port being wireline connected between each radio base station and the service controller. The service controller selects radio base stations for setting up radio links with wireless sets of a calling or called persons, and responds to received signal strengths for handing a radio link from radio base station to radio base station, to maintain the quality of the radio link with an active mobile wireless telephone set. <IMAGE> |
