摘要

The tremendous popularity of wireless technologies during the last decade has created a considerable expansion of wireless networks both in size and use. These facts, together with a great variety of mobile devices and numerous different services that are becoming increasingly resource-demanding, have attracted the attention of many researchers into the area of radio resource planning and optimization. In wireless cellular networks, it is important to develop model or schemes to facilitate effective and efficient utilization of the limited radio resources. In this paper, flowchart for call management scheme through users mobility control is presented. The flowchart along with the analytical expressions pertaining to the scheme are presented and discussed. Particularly, the scheme improves channel allocation to handoff calls for mobile users by considering the direction of their movement. The direction of mobile users with respect to a base station is captured in terms of mobility factor. The mobility factor increases as the user moves closer to a base station. In this case, even if the signal strength of ongoing call of a mobile user is sufficient, it channel allocation can still be retained if its mobility factor is relatively high. In this case, the mobile user will be handed off to the base station it has higher mobility factor value.
