Abstract - The increase in the size of the wireless community together with new applications obliges better utilization of the scarce wireless resources. The requirement for communications on-the-move compels the call admissions mechanism to combat forced call termination. Channels need to be reserved in the surrounding cells, and call admissions must employ mechanisms considering these reservations. Keeping in mind that CDMA has been chosen as the air interface for the 3rd generation, we propose a call admission scheme based on interference. As opposed to the previous work in the literature, we have also developed a realistic mobility model to evaluate our proposal. We model the moving-in-groups behaviour of the subscribers on real maps while respecting the non-pass-through feature of parts of the terrain like households.
