Abstract:
A method of allowing two PHS (Personal Handy-Phone System) slave units respectively connected to two data processing equipment for data communication to directly communicate with each other via radio channels of TDMA (Time Division Multiple Access) frames, said method comprising the steps of:connecting one of said data processing equipment functioning as a server for data communication to one of said PHS slave units, and connecting the other data processing equipment functioning as a client to the other PHS slave unit; causing said PHS slave unit of the server to originate a call addressed to said PHS slave unit of the client via a desired communication channel and thereby setting up synchronization between said PHS slave units with respect to an up-link and a down-link via said communication channel; setting, among m communication slots of a TDMA frame, n (natural number of 1 to m) consecutive communication slots continuing from a slot of said communication channel used for synchronization on at least the down-link extending from one of said PHS slave units to the other PHS slave unit; and causing said PHS slave terminals to interchange data at asymmetrical rates with respect to the up-link and the down-link in respective TDMA frames by respectively using some of the n slots and some of (mâˆ’n) slots.
