Short-Circuited Message Flows for Wireless Location Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location services in wireless communication networks face inefficiencies due to excessive message traffic and prolonged response times, particularly in periodic location reporting, which can be exacerbated by the need for multiple network entities to communicate and verify location information.
Innovation Solution
Implementing short-circuited message flows by allowing wireless devices to directly exchange location estimates with specific network entities, bypassing intermediate nodes, thereby reducing network traffic and response times, and enabling efficient periodic location reporting across various wireless networks and architectures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional message flows are used for location services, then location information can be obtained through multiple network entities for verification and routing, but network traffic increases and response time is prolonged
Solution Approach 1:
The patent extracts and removes intermediate network entities (V-GMLC, H-GMLC) from the message flow when they are not strictly necessary for location verification. The wireless device communicates directly with the R-GMLC, taking out the intermediate GMLC nodes from the path, thereby reducing response time while maintaining essential verification functions through alternative means.
Solution Approach 2:
The patent segments the location service message flow into two distinct paths: a traditional path through V-GMLC and H-GMLC for cases requiring full verification, and a shortened direct path from wireless device to R-GMLC for cases where verification has already been performed or is not required, allowing selective optimization.
2Reliability
If traditional message flows are used for location services, then comprehensive location processing can be performed through multiple network entities, but system resource usage increases
Solution Approach 1:
The patent extracts unnecessary intermediate processing steps involving V-GMLC and H-GMLC from the message flow. By removing these intermediate entities from direct participation in the location request/response exchange, the system reduces the computational and signaling resources consumed by multiple entities while maintaining location processing completeness through the direct device-to-R-GMLC path.
3Productivity
If direct communication between wireless device and R-GMLC is implemented, then response time and network traffic are reduced, but intermediate verification and routing functions may be compromised
Solution Approach 1:
The patent applies preliminary action by performing verification and routing setup in advance through V-GMLC and H-GMLC before the direct communication path is activated. These intermediate entities prepare and validate the direct connection between the wireless device and R-GMLC, ensuring that when direct communication occurs, the necessary verification has already been completed, thus maintaining reliability while achieving efficiency.

AI summary
A user equipment (UE) sends to a serving network a request for periodic reporting of the UE location to a client entity, periodic location information, a request to use GMLC short circuit, and/or a request to use MO-LR short circuit. Various network entities may accept or reject each of the UE requests. For each location reporting event, the UE may send to the serving network its location estimate (e.g., if available and if MO-LR short circuit is allowed) and an address of a requesting GMLC (e.g., if GMLC short circuit is allowed). The network bypasses location processing if the location estimate is selected for use. The serving network may send the location estimate directly to the R-GMLC and bypass a visiting GMLC and a home GMLC, e.g., using the address provided by the UE. The GMLC short circuit and MO-LR short circuit save system resources and shorten response time.
