This paper contributes a new adaptive approach to prevent hando failure due to lack of resources in adjacent cells in a mobile cellular network. Known as the Measurementbased Pre-assignment MPr technique, the technique is useful for implementation in micro pico cellular networks which o ers a Quality of Service QoS guarantee against call dropping. The technique is fully automated, simple, e cient, robust and generic for implementation. The notable feature is that the technique accepts di erent QoS speci cations for di erent grades of hando calls and ensures that these QoS levels are preserved under changing load conditions.
