Localized Service Hosting Network Discovery and Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing policy configurations for selecting hosting networks fail to effectively discover and select a hosting network suitable for accessing and providing localized services.
Innovation Solution
The implementation of service-based hosting network discovery and selection procedures, where user equipment (UE) receives configuration information specifying a hosting network and includes a traffic routing policy rule with a traffic descriptor to identify traffic for routing via the hosting network, allowing for the detection and selection of the appropriate hosting network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing policy configurations are used for selecting hosting networks, then network selection can be performed, but the ability to effectively discover and select a hosting network suitable for localized services is insufficient
Solution Approach 1:
The system performs preliminary actions by receiving configuration information from the serving network before actual network selection is needed. This configuration information includes traffic routing policy rules with traffic descriptors that pre-identify which traffic should be routed via hosting networks, enabling the UE to be prepared for effective discovery and selection when localized services are accessed
Solution Approach 2:
The serving network acts as an intermediary by providing configuration information that mediates between the UE and potential hosting networks. This configuration information serves as a bridge, enabling the UE to discover and select appropriate hosting networks for localized services without direct complex interactions between the UE and multiple hosting networks
2Productivity
If traffic routing policy rules with traffic descriptors are implemented, then traffic can be identified for routing via hosting networks, but configuration complexity increases
Solution Approach 1:
The serving network acts as an intermediary that generates and provides the traffic routing policy rules to the UE. This mediates the complexity by centralizing the configuration generation at the network side rather than requiring complex configuration at the UE side, thus improving traffic routing efficiency while managing configuration complexity at the network level
Solution Approach 2:
The traffic routing policy rules with traffic descriptors serve multiple functions: they identify traffic for routing, specify hosting network selection criteria, and enable localized service access. This multi-functionality improves productivity by consolidating multiple control mechanisms into a single unified configuration structure

AI summary
There is provided a method performed by a user equipment, UE, for allowing the UE to use a localized service in a hosting network, the method comprising: receiving, via a first network connection with a serving network, configuration information, the configuration information specifying the serving network and including a traffic routing policy rule comprising a traffic descriptor for identifying traffic of the localized service to be routed via the hosting network; detecting that a traffic flow matches the traffic routing policy rule; responsive to detecting that the traffic flow matches the traffic routing policy rule, selecting the hosting network; and establishing a second network connection with the hosting network.
