Abstract

Currently this process to determine when to switch between sites is only done when the radio is on the control channel. When a subscriber receives a voice channel grant, the subscriber will transition to the voice channel and suspend the sampling proc- ess. The subscriber will remain on the voice chan- nel until a terminator data packet is received or until the radio fails frame sync for 750 msec. If the radio is moving from an area of good RF coverage to an area of poor RF coverage during a voice call, the process of losing frame sync, trying to find a new control channel, alliliating on the new site and receiv- ing a grant for the call on the new site will cause an audio hole of approximately two seconds in the voice call. This will result in a significant amount ofaudio missed during this transition.
