Communication system for sport interval training, has server using mobile network to control user terminal loudspeaker to give sound output at intensive session start

摘要

A communication system (100) has a server (101) using a mobile communication network (103) to control (105) a user terminal (102). This involves using a program causing the terminal's loudspeaker to emit a sequence of sound pulses at different frequencies, beeps, hums, speech or music that are repeated on a display and indicate to the user that an intensive sporting training period has started. The program is preferably a Java computer program.
