    • This invention relates to a wireless communication system, which comprises plural wireless communication units having different communication protocols, and in which a proper wireless communication unit is automatically selected from the plural wireless communication units in accordance with the operation states of the plural wireless communication units to make communication possible. Thereby, troublesome operation is not required, an optimum wireless communication method can be automatically selected, and communication cost can be reduced. In the wireless communication system of the present invention, when mobile stations are registered in a fixed station, preferential orders of the mobile stations are stored, and calling/call-reception and communication processings are controlled according to the preferential orders.
    • 本发明涉及一种无线通信系统,其包括具有不同通信协议的多个无线通信单元,其中根据多个无线通信单元的操作状态从多个无线通信单元自动选择适当的无线通信单元, 使沟通成为可能。 因此,不需要麻烦的操作,可以自动选择最佳的无线通信方法,并且可以降低通信成本。 在本发明的无线通信系统中,当在固定台登记移动站时,存储移动站的优先顺序,根据优先顺序控制呼叫/呼叫接收和通信处理。
