<P>PROBLEM TO BE SOLVED: To provide a radio call system that can prioritize a call of some of multiple slave units and also enables other slave units to make a call even in the situation that some slave units are prioritized. <P>SOLUTION: A radio call system (1) includes a master unit (100) and multiple slave units (200a)-(200g), and is a radio communication system in which a calling side slave unit and a receiving side slave unit perform wireless communication via the master unit (100). The calling side slave unit transmits call transmission data, and the master unit (100) receives the call transmission data transmitted by the calling side slave unit, and transmits the call transmission data by allocating slots to the call transmission data by a time division multiple access system according to a set call mode. The receiving side slave unit receives the call transmission data transmitted by the master unit (100), and reproduces the call transmission data. The call mode includes a first call mode in which the master unit (100) preferentially allocates a part of the slots to the call transmission data of the calling side slave unit according to the priority of the calling side slave unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
