<p>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 (figure 1). A trigger criteria threshold is determined for the mobile device (S1). 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 (S3). 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 (S7). 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.</p> |
