Base Station Mobility Management via Timer-Based Binding Updates

The patent divides the centralized mobility management function into distributed components at multiple base stations. Each base station maintains local mobility management capabilities, segmenting the previously centralized function. This allows terminals to be managed by their current serving base station rather than requiring all traffic to route through a centralized core network agent, improving routing efficiency while maintaining mobility management capabilities.

By distributing mobility management functions across multiple base stations rather than concentrating them in a single centralized agent, the system eliminates single points of failure. Each base station can independently manage terminals in its coverage area, providing redundancy and fault tolerance. If one base station fails, others continue to operate, maintaining system reliability.

The patent segments the traffic flow by allowing direct local routing between base stations and terminals without requiring all traffic to pass through centralized core network agents. This reduces unnecessary traffic traversal through the core network, improving network efficiency and reducing energy consumption associated with long-distance traffic routing.

The patent implements periodic binding updates at optimized intervals rather than continuous or overly frequent updates. The system determines appropriate update timing based on terminal mobility patterns and network conditions, performing updates only when necessary to maintain accurate location information. This reduces signaling overhead while maintaining sufficient location tracking accuracy for seamless mobility management.
