Network Slice Mapping via Route Selection Policies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no standardized way to identify applications and their requirements across platforms, making it difficult for telecommunications networks or service providers to manage and map applications to network slices, especially with the increasing number of available applications on multiple mobile platforms, and service providers lack control over UE devices' modems or operating systems.
Innovation Solution
A partnership or subscription service is formed between a service provider and an application provider, allowing the service provider to control which applications access specific network slices by verifying authorization and updating User Equipment (UE) devices' Route Selection Policies (URSP) to ensure applications are mapped to optimal slices based on their requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service providers allow applications to access multiple network slices without standardized identification, then application compatibility across platforms is improved, but network traffic management and slice mapping become unmanageable
Solution Approach 1:
The patent introduces standardized identification parameters (application identifiers, slice identifiers, and mapping rules) to transform the unmanageable mapping process into a controllable system. By defining specific parameters for application-slice correspondence, the system can efficiently manage traffic while maintaining compatibility across diverse applications and platforms.
2Ease of operation
If service providers implement centralized control over UE devices' modems or operating systems, then network slice mapping control is improved, but device autonomy and user privacy are compromised
Solution Approach 1:
The patent introduces an intermediary component (the standardized mapping mechanism) that operates between the service provider's network and the UE device's modem/OS. This intermediary enables controlled slice mapping through standardized interfaces without requiring direct access to or modification of the device's internal operating system or modem, thus preserving device autonomy while achieving mapping control.
3Measurement precision
If manual mapping methods are used for each application, then mapping precision is improved, but the time and resources required for management increase significantly
Solution Approach 1:
The patent implements preliminary action by pre-defining standardized identification rules and mapping criteria for applications and network slices. Instead of performing manual mapping for each application in real-time, the system establishes mapping rules in advance, allowing automated and efficient slice assignment when applications access the network, thereby reducing management time while maintaining mapping precision.
