Wireless Network Slice Allocation for User Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks often allocate user applications to wireless network slices that do not meet performance requirements, leading to suboptimal performance or unnecessary costs, and fail to efficiently assist User Equipment (UE) in using the optimal network slices for newly downloaded applications.
Innovation Solution
The implementation of a mechanism where the Network Exposure Function (NEF) and Network Control Plane select and allocate optimal wireless network slices based on application requirements, using Radio Resource Control (RRC) reconfiguration to ensure that user applications operate on slices that best match their performance needs, thereby optimizing resource utilization and cost alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user applications are allocated to wireless network slices without optimization, then network setup is simple, but application performance is suboptimal and costs are unnecessary high
Solution Approach 1:
The system performs preliminary actions by analyzing application requirements before application execution and pre-configuring the appropriate network slice. The NEF receives application requirements, matches them with suitable network slices in advance, and establishes the connection before the application needs to run, ensuring optimal performance without manual intervention.
Solution Approach 2:
The Network Exposure Function (NEF) acts as an intermediary between user applications and network slices. It receives application requirements, determines suitable network slices, and manages the allocation process, thereby simplifying the complexity while ensuring optimal performance matching.
2Reliability
If high-performance wireless network slices are allocated to all applications, then application performance is guaranteed, but network costs increase unnecessarily
Solution Approach 1:
The system applies local quality by matching specific network slice characteristics to specific application requirements. Different network slices with different performance levels are allocated to different applications based on their individual needs, rather than uniformly allocating high-performance slices to all applications, thereby avoiding resource waste.
Solution Approach 2:
The system changes parameters by dynamically adjusting network slice allocation based on application requirements. It evaluates parameters such as throughput, latency, and reliability needs of each application and selects network slices whose parameters match the application's performance requirements, optimizing resource utilization.
3Reliability
If manual configuration of network slices for each application is performed, then optimal performance can be achieved, but operational complexity and time consumption increase
Solution Approach 1:
The system enables self-service by allowing applications to automatically receive appropriate network slice allocation without manual configuration. The NEF autonomously analyzes application requirements, selects suitable network slices, and establishes connections, eliminating the need for manual intervention while maintaining optimal performance.
Solution Approach 2:
The system uses feedback by continuously monitoring application performance requirements and adjusting network slice allocations accordingly. The NEF receives feedback about application needs and network slice performance, enabling dynamic optimization without manual configuration.

AI summary
A wireless communication device wirelessly downloads a user application, and in response, wirelessly receives signaling that indicates a wireless network slice for the user application. The wireless communication device wirelessly downloads another user application, and in response, wirelessly receives other signaling that indicates another wireless network slice for the other user application. The wireless communication device executes the user application, and in response, wirelessly transfers a request for the wireless network slice and wirelessly exchanges application data for the user application over the wireless network slice for the user application. The wireless communication device executes the other user application, and in response, wirelessly transfers another request for the other wireless network slice and wirelessly exchanges other application data for the other user application over the other wireless network slice for the other user application.
