Mobile Hand-Off Based on Base Station Priority

The patent applies local quality by differentiating base stations into priority groups (first priority, second priority, third priority) based on their cell size and location characteristics. Instead of uniform treatment, the system assigns different hand-off priorities to different base stations, causing mobile devices to preferentially select smaller cells over larger cells. This resolves the contradiction by maintaining reliable hand-offs through priority-based selection while preventing larger cells from becoming overloaded.

The patent segments the network into hierarchical levels with base stations organized into priority groups. Smaller cells are assigned higher priority levels than larger cells, creating a segmented hand-off strategy where mobile devices are directed to smaller cells first. This segmentation allows larger cells to maintain their coverage function while reducing their load, as smaller cells handle the bulk of mobile device connections.

The patent implements self-service by enabling mobile communication devices to autonomously perform hand-off decisions based on priority information received from base stations. Instead of requiring continuous network-controlled load balancing with complex signaling, the network provides priority information and mobile devices independently select target base stations. This dramatically reduces signaling complexity while maintaining effective load distribution.
