5G NR n77 Frequency Selection via Service Entitlement Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G NR user equipment (UE) may not be capable of operating in all frequency ranges of the n77 band, such as the 3450-3550 MHz and 3700-3980 MHz ranges, leading to inconsistent service provision to customers with varying rate plans.
Innovation Solution
A system that dynamically controls frequency range usage by user equipment (UE) based on subscriber rate plans, using a service entitlement server (SES) to authenticate and authorize frequency ranges, and adjusts radio resources in real-time with AI assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network operator offers 5G service across multiple frequency ranges in the n77 band, then service coverage and versatility are improved, but device compatibility and ease of operation deteriorate because user equipment may not be capable of operating in all frequency ranges
Solution Approach 1:
The patent implements dynamic frequency range selection where the network dynamically determines and assigns appropriate frequency ranges based on real-time assessment of UE capabilities. The system transitions from static frequency allocation to dynamic adaptation, where frequency ranges are selected and reconfigured based on current network conditions and device capabilities, resolving the contradiction between versatile service coverage and device compatibility.
Solution Approach 2:
The patent applies local quality by customizing frequency range assignments for individual UEs based on their specific capabilities. Each UE receives a tailored frequency configuration matching its operational capabilities, rather than a uniform frequency assignment for all devices. This localized approach ensures optimal service delivery for each device type while maintaining overall network versatility.
2Adaptability or versatility
If the network dynamically adjusts frequency ranges based on subscriber rate plans, then service customization and adaptability are improved, but system complexity and device complexity increase due to the need for authentication and authorization mechanisms
Solution Approach 1:
The patent introduces an intermediary authentication and authorization mechanism that mediates between the UE capability information and the frequency range selection. This intermediary layer handles the complex logic of matching subscriber rate plans with appropriate frequency ranges, shielding the UE from the complexity of authorization protocols while enabling customized service delivery. The intermediary manages the interaction between network policies and device capabilities.
3Productivity
If the network optimizes radio resources in real-time based on UE capability reports, then network performance and productivity are improved, but information processing requirements and measurement precision requirements increase
Solution Approach 1:
The patent implements preliminary action by collecting and processing UE capability information in advance before actual data transmission begins. The system proactively gathers UE capability reports, authenticates subscribers, and pre-determines appropriate frequency ranges and resource allocations. This preliminary processing prevents information loss during real-time operations by ensuring all necessary capability data is available before resource optimization decisions are made.
