Frequency Band Combination Priority for 5G UE Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-layered 5G deployments, providing the best service experience for User Equipment (UEs) is challenging due to the complexity of multiple frequency bands and cell bandwidths, which limits the ability to serve a maximum number of UEs while meeting desired service experience.
Innovation Solution
A system that receives UE band capabilities, determines frequency band combinations based on these capabilities, identifies optimal combinations for dynamic latching, configures the UE to perform frequency measurements, and facilitates latching to frequency bands with higher priority values to improve user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple frequency bands and carriers are deployed to increase network capacity and coverage, then network competitiveness and service quality improve, but system complexity and difficulty in providing best service experience increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting frequency band selection based on UE capabilities, current frequency band, and priority values. The system changes operational parameters (frequency band combinations) to optimize service quality without increasing system complexity, resolving the contradiction between network capacity and system complexity.
2Area of stationary object
If coverage-based handover is used in multi-layer deployments, then network coverage is extended, but ability to provide best service experience considering UE capabilities and network layout deteriorates
Solution Approach 1:
The patent implements dynamic frequency band latching that adapts to UE capabilities and network conditions. Instead of static coverage-based handover, the system dynamically selects frequency bands based on real-time parameters including UE band capabilities, current frequency band, and priority values, thereby improving service experience while maintaining coverage.
Solution Approach 2:
The system uses feedback mechanisms by continuously evaluating UE capabilities, current frequency band status, and priority values to make informed decisions about frequency band latching. This feedback-driven approach ensures optimal service experience while maintaining network coverage.
3Reliability
If frequency band combinations are selected without priority values, then UE can connect to available bands, but user experience in terms of data rates, voice quality, and battery conservation deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-defining priority values for different frequency band combinations based on UE capabilities and network layout. This preliminary configuration enables the system to make optimal frequency band selections that enhance user experience (higher data rates, better voice quality, battery conservation) while ensuring connection availability.
Data Source
AI summary
User Equipment (UE) band capabilities are received from a UE. A set of frequency band combinations are determined for the UE based on the UE band capabilities. Each frequency band combination of the set of frequency band combinations includes a group of frequency bands, and a frequency band combination priority value. Further, one or more frequency band combinations are identified from the set of frequency band combinations based on a current frequency band of the UE and the frequency band combination priority value. The UE is configured to perform frequency measurements for a plurality of frequency bands based on the one or more identified frequency band combinations. The UE is dynamically facilitated to latch to at least one frequency band based on the frequency measurements of the plurality of frequency bands.
