Abstract :
In the current implementation of the CT2 systems in Singapore, only handset initiated calls are allowed. This paper will describe a design to allow two-way calling for the CT2 system with minimal modification to the current CT2 infrastructure as well as the public switched telephone network (PSTN). The design makes use of centralized databases in the home location register (HLR) and visitor location register (VLR) to track the location of the handsets. We carried out a computer simulation of the proposed system to determine the potential area of congestion in the system
