Network Discovery for Localized Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems lack a process for user equipment (UE) to discover and select networks providing localized services, especially in public network environments.
Innovation Solution
The method involves initiating network discovery from a trigger event, receiving broadcast information about available networks supporting localized services, constructing a list of available networks, and selecting an appropriate network for registration, which can be automatic or manual.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional network selection procedures are used, then UEs can connect to established PLMN networks, but UEs cannot discover networks providing localized services in public network environments
Solution Approach 1:
The patent applies preliminary action by having UEs pre-configured with service area information and localized service identifiers before entering public network environments. When trigger events occur (such as entering a geographic area or detecting specific conditions), the UE proactively initiates network discovery procedures for localized services rather than waiting for conventional PLMN selection to complete. This allows the UE to discover and connect to suitable networks providing localized services without adding significant complexity to the overall network selection process.
2Ease of operation
If UEs are steered only to operator-established networks, then network management is simplified, but access to localized services in limited time or location is prevented
Solution Approach 1:
The patent introduces an intermediary mechanism where the UE maintains both conventional operator-controlled PLMN selection capabilities and enhanced discovery capabilities for localized services. The service area information and localized service identifiers act as intermediaries that bridge the gap between operator-managed networks and localized service providers. This allows the UE to access both operator-established networks for reliable connectivity and localized service networks when needed, without compromising the reliability of either system.
3Productivity
If automatic network selection is used, then network connection is streamlined, but user control over localized service access is reduced
Solution Approach 1:
The patent implements dynamics by making the network selection process adaptive and configurable. The system supports multiple modes of operation: fully automatic network selection for streamlined connectivity, manual selection when users want control over which localized services to access, and hybrid modes where certain conditions trigger automatic discovery while others require user confirmation. The UE can dynamically adjust its behavior based on user preferences, service types, and environmental conditions, allowing both fast automatic connection and user control to coexist.
Data Source
AI summary
Various aspects of the present disclosure relate to a method, apparatus and system that support discovery of a network supporting a localized service. A method for network discovery performed by user equipment in a telecommunications network includes initiating the network discovery based on a trigger event, receiving broadcast information comprising an indication indicating availability of at least one network supporting a localized service, constructing a list of available networks supporting the localized service, and selecting a first network from the list of available networks. The selected network may be a network other than the home network of the user equipment that provides localized services at a particular time and/or location.
