Tracking Area List Allocation Using Historical Movement Data

The patent segments the Tracking Area into multiple smaller sub-areas, each with its own TA ID. Instead of allocating a single TA ID that covers a large area, the network divides the coverage area into segments (sub-TAs) and allocates multiple sub-TA IDs to the UE. This segmentation allows the UE to remain within a smaller allocated area for longer periods, reducing the frequency of TA update procedures and signaling overhead while maintaining accurate mobility management.

The patent applies preliminary action by having the UE report its movement trajectory information to the network before the MME makes allocation decisions. The UE provides historical movement data including previously visited TA IDs and movement patterns. The MME uses this pre-collected information to predict future movement areas and proactively allocates an optimized TA List that anticipates where the UE will move, thereby reducing future TA updates while having sufficient information to make accurate allocations.

The patent implements feedback by establishing a closed-loop system where the UE continuously reports its current TA ID and movement trajectory to the MME. The MME uses this feedback information to evaluate the effectiveness of previously allocated TA Lists and to dynamically adjust future allocations. The feedback mechanism provides the MME with accurate real-time information about UE movement patterns, enabling optimized TA List allocation that reduces location updates and improves network resource utilization without excessive complexity.
