METHOD AND APPARATUS FOR IMPLEMENTING A HARD HANDOVER IN BOUNDARY AREA

摘要

A method and apparatus for implementing a hard handover in boundary area are provided, and the method includes: when a mobile terminal which is on a basic frequency of the border cell of the first BSC (Base Station Controller) is moving from coverage area of the basic frequency of the border cell of the first BSC towards the coverage area of basic frequency of the border cell of the second BSC, determining whether a first predetermined handover condition is satisfied, if the first predetermined handover condition is satisfied, then performing an inter-frequency hard handover and handing over the mobile terminal to an interim frequency provided by the first BSC which is different from the basic frequency of the first BSC. Another method for implementing a hard handover in boundary area and a BSC capable of implementing a hard handover in boundary area are also disclosed. The present invention employs the wide coverage characteristic of the interim frequency and avoids the phenomenon of ping-pong hard handover that easily occurs in intra-frequency hard handover area.
