Relay Apparatus Location Request Routing with Regional Segmentation

The patent segments the location information request into distinct components: regional information (for identifying the target area) and eNB identification information (for identifying specific base stations). This segmentation allows the system to first narrow down the search area using regional information, then identify specific eNBs within that region, thereby improving location information accuracy while maintaining manageable message structure complexity through modular organization.

The patent adds a new dimension of regional information to the existing location information request structure. Instead of directly specifying only eNB identifiers, the system introduces a regional dimension that provides contextual information about the target area. This dimensional addition enables more precise location information acquisition by first establishing the regional context before identifying specific eNBs, thus resolving the contradiction between accuracy and complexity.

The patent applies preliminary action by including Global eNB IDs in the location information request before the actual message routing process. By pre-specifying the target eNB identifiers along with regional information, the system enables the receiving end to immediately identify the correct destination without requiring additional routing resolution steps. This preliminary inclusion of routing information ensures accurate message delivery while the structured organization of the request maintains manageable complexity.

The patent uses regional information as an intermediary element that bridges the gap between the requestor and the target eNB. Instead of directly establishing a point-to-point connection, the regional information acts as a mediator that first establishes the target area context, then allows specific eNB identification within that region. This intermediary approach ensures reliable routing while distributing the complexity across multiple manageable fields rather than requiring a single complex identifier.

The patent segments the location information request into regional information and eNB identification information, which enables selective transmission to multiple HeNBs within a specific region. By first defining the target region and then identifying relevant eNBs within that region, the system can efficiently aggregate location data from multiple sources without unnecessary complexity in the request transmission process. The segmented structure allows systematic iteration over multiple eNBs while maintaining clear request semantics.

The patent makes the location information request structure universal by designing it to work effectively whether sent to a single eNB or multiple eNBs. The request format with regional information and eNB identifiers can be applied consistently across different scenarios, enabling the same request mechanism to aggregate location data from multiple HeNBs when needed. This multi-functionality reduces system complexity by using a single request type for various purposes rather than requiring different request formats for single versus multi-target scenarios.
