• The demand for data communication over Personal Handy-phone System (PHS) is expected to rapidly increase in the near future. Some applications based on the circuit-switched services have been recently developed. However, the packet-switched service is better than the circuit-switched service for personal data communications in terms of the flexible utilization of radio resources. In this paper, we propose PHS with packet data communications system (PHS-PD), which has four system concepts; (i) to support the Internet access, (ii) to realize compatibility with circuit-switching services, (iii) to share the common radio channels with circuit-switched calls, and (iv) to utilize idle time slots for packet data. Moreover, a novel packet channel structure for sharing radio resources with circuit-switched calls is introduced. Although packet data are transferred using common radio resources, the proposed channel structure prevents any degradation in call loss performance of the circuit-switching service. An evaluation of the maximum packet transmission rate shows that PHS-PD can offer a data communication rate of 20.1 kbps even if circuit-switched calls are in progress. Furthermore, up to 83.6 kbps is possible if circuit-switched calls are quiescent. It is also shown that enough capacity for a practical e-mail service can be ensured by PHS-PD even if the degradation of throughput performance due to packet collisions on random access channels is considered.
