Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current frequency refarming techniques require extensive frequency planning and optimization, making it challenging to dynamically reuse frequency resources from one communication technology to another, especially when transitioning between different communication technologies like GSM and HSPA or LTE, which can lead to increased complexity and costs in cellular networks.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If frequency resources are statically assigned to a specific communication technology, then frequency planning is simplified, but the adaptability to different communication technologies is reduced
Solution Approach 1:
The patent implements dynamic frequency refarming where frequency resources are not statically assigned but dynamically allocated based on real-time network status. The network entity monitors network conditions and automatically adjusts frequency resource allocation between different communication technologies (e.g., GSM, WCDMA, LTE), enabling the system to adapt to changing network demands and technology transitions without requiring extensive manual frequency planning.
2Adaptability or versatility
If frequency resources are dynamically reused between different communication technologies, then adaptability is improved, but frequency planning complexity increases
Solution Approach 1:
The patent employs a self-service mechanism where the network entity autonomously monitors network status information and automatically makes decisions about frequency resource allocation. The system uses pre-configured refarming policies and rules to determine when and how to refarm frequency resources between different communication technologies, eliminating the need for complex manual frequency planning and optimization while maintaining high adaptability.
Solution Approach 2:
The patent implements a feedback mechanism where the network entity continuously monitors network status information (such as traffic load, signal quality, and resource utilization) and uses this feedback to dynamically adjust frequency resource allocation. The refarming decisions are based on real-time network conditions and predefined policies, allowing the system to automatically optimize frequency resource usage without increasing planning complexity.
3Reliability
If manual frequency planning is performed for refarming, then frequency resource allocation is controlled, but the transition time between communication technologies increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring refarming policies and rules in the network entity before actual frequency refarming is needed. These policies define the conditions and parameters for frequency resource allocation between different communication technologies. When refarming is triggered, the system can immediately execute the pre-planned actions based on current network status, significantly reducing transition time while maintaining controlled and reliable frequency resource allocation.
