Abstract

As currently envisioned, the Japanese cellular mobile telephone system ('JTACS") will require up to 180 channels per cell. This is far above the current 120 voice channels capacity of cellular base sites commercially available from Motorola. In addition, the signaling rate of the paging and access channels is being reduced from 10,000 bits per second to 4000 bits per second to accommodate the narrower bandwidth of the JTACS RF channels. As a consequence, it would be helpful if the JTACS system had additional procedures for assign- ing and acquiring paging and access channels thereby providing more flexibility than either the U.S. or U.K. cellular systems currently have. This would alleviate the access limitation of the JTACS signaling channels due to the reduced bit rates.
