  • Apparatus and method for facilitating efficient handover
    Patent number: 8259680
    Abstract: A method and apparatus facilitating efficient handover by a wireless communications device is provided. The method may comprise obtaining at least two handover metrics for a target cell and for a serving cell, wherein the at least two handover metrics are determined by a request received from the serving cell, determining if all the obtained handover metrics for the target cell are greater than or equal to corresponding threshold values, wherein the corresponding threshold values for the at least two handover metrics are determined by the request received from the serving cell, determining if at least one of the obtained handover metrics for the serving cell is less than the corresponding threshold value, and generating a measurement report indicating the target cell as a handover candidate cell.
