METHOD AND APPARATUS FOR SOFT HANDOVER AREA DETECTION USING INTER-BAND MEASUREMENTS |
摘要 |
A method and system for soft handover area detection for uplink interference avoidance that includes a network device and mobile device in a communications network. A trigger criteria threshold is determined for the mobile device. The mobile device is using a downlink carrier. If a trigger criteria has risen above or fallen below the trigger criteria threshold, inter-frequency measurements of co-sited cells are performed and compared to determine if a soft handover area exists. Co-sited cells are searched for downlink carriers and reselection is initiated from the downlink carrier to a co-sited cell downlink carrier if the co-sited cell downlink carrier is useable by the mobile device. Reselection is initiated from the downlink carrier to a non co-sited cell downlink carrier if no co-sited cell downlink carrier useable by the mobile device is found. The system provides for reselection while uplink carrier interference is avoided. |
