Radio Access Network Device Update for Service-Specific Feature Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecom operators face challenges in optimizing communication network features due to varying requirements from diverse terminal devices, leading to increased complexity and costs, as not all features are necessary for all areas, and existing technologies like Software Defined Radio (SDR) do not efficiently address the need for updating network nodes to support specific services requested by terminal devices.
Innovation Solution
A method and system for updating radio access technology characteristics in network devices, where a core network node receives requests from terminal devices, determines if the radio access network device is updateable, retrieves and delivers a data package to update the device to support the requested service, and optionally updates the terminal device, based on technical and commercial criteria such as narrow-band IoT characteristics, frequency bands, and data speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all possible features are acquired for all base stations, then service coverage and capability are improved, but network cost and complexity increase
Solution Approach 1:
The patent implements preliminary action by proactively detecting terminal device service requirements and preparing appropriate feature configurations before service execution. The network device receives service requirement information, determines corresponding feature sets in advance, and configures radio resources accordingly, preventing the need for all base stations to have all features simultaneously active.
Solution Approach 2:
The patent applies local quality by configuring features specifically where and when they are needed rather than uniformly across the entire network. The system determines feature configurations based on local service requirements, terminal device capabilities, and radio conditions, enabling selective feature activation in specific network areas and time periods.
2Loss of energy
If features are optimized based on terminal device distribution, then network cost is reduced, but service responsiveness and adaptability worsen
Solution Approach 1:
The patent implements feedback mechanisms where the network device continuously monitors terminal device service requirements, radio conditions, and feature usage effectiveness. This feedback loop enables dynamic adjustment of feature configurations, allowing the network to respond to changing service demands while maintaining cost efficiency through selective feature activation based on actual observed needs.
Solution Approach 2:
The patent applies dynamics by making feature configurations adaptable and changeable rather than static. The system can dynamically determine and switch between different feature sets based on real-time service requirements, terminal device movements, and network conditions, enabling cost-effective operation while maintaining service responsiveness.
3Device complexity
If traditional one radio unit per frequency and service model is used, then device simplicity is maintained, but network adaptability and feature flexibility worsen
Solution Approach 1:
The patent applies universality by enabling a single radio unit to perform multiple functions and support multiple services through dynamic feature configuration. The network device can allocate different feature sets to the same radio unit based on service requirements, allowing one radio unit to serve multiple frequencies and service types sequentially, replacing the traditional one-to-one mapping model.
Solution Approach 2:
The patent makes the radio unit configuration dynamic, allowing features and service allocations to change over time based on demand. The same radio unit can be reconfigured for different services, frequencies, and feature sets at different times, providing feature flexibility and adaptability while maintaining physical device simplicity.
