Title: Digital mobile telephone system
Inventor: ADACHI KEIZO
IPC: H04W76/00
Filed: 1992-03-06
Abstract: PURPOSE:To increase connection processing quantity by setting a half rate for a call of communication when the use of the channel of a radio base station is concentrated. CONSTITUTION:When a call is issued from a mobile telephone terminal (MSS) 1, the radio base station (MBS) 2 receives a call issuing signal, and a control part (CTL) 23 judges whether or not traffic congestion occurs on a radio channel. When it is decided that the traffic congestion occurs, the CTL 23 sends out a half rate request signal to the MSS 1. The MSS 1 judges whether or not a CTL 13 half rate can be set, and a CTL 13 transmits a feasibility signal to the MBS 2 when the communication is being performed. The CTL 23 transmits a half rate start signal to the MSS 1, and allocates one channel to the MSS 1, and makes a data compression part (HRT) 22 compress speech data by issuing an instruction. The MSS1, when receiving the half rate start signal, reduces input information quantity to a CTL13 digital/analog converter (D/A) 12 to the half, and makes it perform analog conversion.
