VAL Service Area IDs for SEAL Server UE Location Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face challenges in seamlessly integrating and managing Vertical Application Layer (VAL) service areas as location identification attributes, leading to inefficiencies in service delivery and coordination among various VAL service providers, particularly in the context of emerging technologies like 5G and 6G mobile communication systems.
Innovation Solution
Incorporating a VAL service area as a location identification attribute within a Service Enabling Architecture Layer (SEAL) server, enabling seamless automatic service delivery by using a VAL service area ID for UE location management, grouping, and monitoring, thereby eliminating the need for explicit geographical coordinates in each request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If explicit geographical coordinates are used for each location request, then location identification precision is improved, but device complexity and operational complexity increase due to the need to manage and process multiple coordinate sets
Solution Approach 1:
The patent introduces a VAL service area as an intermediary abstraction layer between the user's geographical location and the service delivery system. Instead of directly managing raw geographical coordinates, the system uses VAL service areas as mediators that encapsulate location information, thereby reducing system complexity while maintaining location identification precision through the mapping between service areas and geographical coordinates.
Solution Approach 2:
The patent segments the location management function by separating the geographical coordinate storage (maintained by the network) from the service area identification (used by VAL servers). This segmentation allows the system to handle location information at different levels of abstraction, reducing the complexity of processing individual coordinate requests while preserving precise location identification through the hierarchical structure of service areas.
2Adaptability or versatility
If multiple VAL service providers manage their own service areas independently, then adaptability and service specificity are improved, but loss of information occurs due to lack of centralized coordination and shared location data
Solution Approach 1:
The patent implements a universal VAL service area framework that serves multiple functions simultaneously: it provides service-specific location identification for individual VAL providers while also enabling centralized location management and coordination. The service area structure acts as a multi-functional platform that supports both the specificity of individual services and the information sharing needs of the broader ecosystem, eliminating data loss through standardized interfaces and centralized databases.
3Measurement precision
If the system processes location requests for each UE individually, then measurement precision and location accuracy are improved, but productivity decreases due to increased processing time and network load
Solution Approach 1:
The patent merges the location management functions for multiple UEs into a unified service area framework. Instead of processing location requests individually for each UE, the system combines them into collective service area queries, thereby improving productivity by reducing the number of processing operations while maintaining location accuracy through the structured mapping between service areas and geographical coordinates. This merging enables batch processing and reduces network load significantly.
Data Source
AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a vertical application layer (VAL) server in a wireless communication system is provided. The method comprises transmitting, to a location management server, a user equipment (UE) information request message including a first VAL service area identity (ID) of a first VAL service area and receiving, from the location management server, UE information as a response to the UE information request message. The UE information includes a list of at least one UE whose location is within an application defined proximity range of the first VAL service area corresponding to the first VAL service area ID, and the application defined proximity range includes a range in which the UE information is required.
