ABSTRACT

In Code division Multiple Access (CDMA) based cellular network, all cells share the same frequency bands and user can transmit simultaneously. In hard handoff, the old radio link is established and a handset always communicates with on base station (BS) at any given time. In the handoff procedure, the network needs to set up the new voice path for the handoff call. This setup time is referred as the network response time. If the old radio link is disconnected before the network completes the setup, the call is forcedly terminated. In this paper we introduce the concept of overlap region between adjacent cells and develop an analytical model for hard handoff in CDMA system. Balking and reneging behaviors of calls have also considered in this model. Different performance measures using variation in different parameters are calculated and results have been analyzed graphs.

Keywords :CDMA, Handoff, Base station, overlap region.
