Abstract

A method for improved sector handoff within a sectorized communication cell utilizing a wireless communication systems. A sector handoff of a mobile radio telephone is performed in accordance with a first set of parameters if the mobile radio telephone is not in close proximity to a base antenna. Sector handoff of the mobile radio telephone is performed in accordance with a second different set of parameters when the mobile radio telephone is in close proximity of the base antenna. The second different set of parameters are utilized in close proximity to the base antenna to avoid drops and adverse handoffs in high interference, low signal strength areas and provide improved sector handoff when the mobile radio telephone encounters distorted conditions, such that improved sector handoff can be achieved.
