Using the existing GSM network for location is currently a hot, but usually the system only can complete the location function, and could not communication with others. For the purpose of the voice communication between the mobile terminals in forklifts and the service center, this paper designed a new emergency call system to overcome the above disadvantages, and especially taken their applications into consideration.
