It is divided into The first slot TS0 of each frame is
It includes a frame synchronization signal F and a 5-bit group call-in signal C corresponding to each terminal group. The group call-in signal C individually notifies each terminal of whether there is an incoming call in the frame.

される。First, all the terminal groups receive the slot TS0, set the timing of the frame, and confirm the presence or absence of an incoming call to the own group by the group incoming call signal C. Here, it is assumed that the group incoming signal C is assigned to each terminal group bit by bit, and the terminal group corresponding to the bit indicating "1" has an incoming call instruction. In the figure, since the second and fifth bits are "1", it is confirmed that there is an incoming call instruction for the second group and the fifth group.

Slots in which only terminals in the group are assigned to each group
Terminals belonging to other groups receive TS2 and TS5 and do not perform receiving operation until TS0 of the next frame.In this way, by setting the group incoming signal in the first slot TS0 of the frame, each terminal It is not necessary to constantly receive the slots assigned to the group, and particularly when applied to a receiving system using a small battery, the battery consumption is small and the practicality can be improved.

い。In the above embodiment, the terminals are grouped into five groups (N
However, the present invention is not limited to this and can be arbitrarily set in 4 groups or less or 6 groups or more. Further, although one bit is assigned to each group terminal in the group incoming signal, any number of bits may be configured for each group, and the presence of the incoming instruction may be notified by "0". .
