User Equipment Route Selection Across Mobile Technologies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication technologies, such as LTE and certain versions of 5G, lack the User Equipment Route Selection Policy (URSP) functionality, which limits the ability to configure network route selections for applications across multiple mobile communication technologies, making it difficult to manage network traffic effectively and apply differentiated routing or policy treatments.
Innovation Solution
Enabling URSP functionality across multiple mobile communication technologies, including 5G Core, 5G Option 3×, and LTE, by allowing user equipment to perform route selection using User Equipment Route Selection Policy rules and mapping data structures, enabling flexible routing and policy treatments based on application identifiers and network slice information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If URSP functionality is implemented only in 5G Core network, then route selection capability is improved, but network coverage and compatibility are worsened
Solution Approach 1:
The patent extends URSP functionality from 5G Core to both 5G Option 3× and LTE networks, enabling a single UE to perform route selection across multiple mobile communication technologies. This multi-functionality allows the same UE to apply differentiated routing policies whether connected to 5G Core, 5G Option 3×, or LTE network, thereby improving adaptability without requiring separate implementations for each network type.
Solution Approach 2:
The patent introduces a mapping data structure as an intermediary that translates URSP rules from 5G Core terminology into network-specific formats for 5G Option 3× and LTE. This mapping mechanism enables URSP functionality to operate across different network technologies by converting and adapting the route selection policies to match each network's specific requirements, thus expanding coverage while maintaining capability.
2Speed
If URSP rules are applied without mapping data structures, then route selection speed is improved, but compatibility across different network technologies is worsened
Solution Approach 1:
The patent pre-configures mapping data structures that define how URSP rules should be translated and applied to different network technologies before actual route selection occurs. These pre-established mappings enable the UE to quickly interpret and apply URSP rules across 5G Core, 5G Option 3×, and LTE networks without performing complex real-time conversions, thus maintaining speed while ensuring compatibility.
3Productivity
If differentiated routing is implemented for specific applications, then network traffic management is improved, but system complexity is worsened
Solution Approach 1:
The patent segments network traffic management by applying differentiated routing policies to specific applications or service types through URSP rules. Instead of treating all traffic uniformly, the system divides traffic into distinct categories (e.g., voice, data, video) and applies appropriate routing treatments to each segment. This segmentation improves traffic management productivity while keeping the complexity manageable through structured policy definitions.
Solution Approach 2:
The patent utilizes parameter changes in the mapping data structure to adapt routing behavior for different applications and network conditions. By modifying parameters such as priority, QoS requirements, and routing preferences based on application type and network state, the system achieves differentiated routing without requiring complex custom logic for each scenario, thus improving traffic management while controlling system complexity.
Data Source
AI summary
The described technology is generally directed towards enabling user equipment to perform route selection across multiple mobile communication technologies. User equipment route selection allows specifying, by the user equipment, information which affects the way the user equipment's network communications are handled by a communication network. User equipment route selection across multiple mobile communication technologies enables certain route selection capabilities whether the user equipment is connected to a 5G Core network mobile communication technology, a 5G Option 3× network mobile communication technology, or a LTE network mobile communication technology.
