Service Entitlement Server for UE Band Frequency Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) may not be capable of operating in all frequency ranges of the 5G NR n77 band, particularly the 3450-3550 MHz range, leading to inconsistent and inefficient service provision to customers with varying rate plans.
Innovation Solution
A system that dynamically controls frequency range usage based on UE capability and subscriber rate plans, involving a service entitlement server (SES) that authenticates and authorizes frequency ranges, adjusts the UE's capability matrix, and directs communication using authorized frequency ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network operator offers 5G service in multiple frequency ranges (e.g., 3700-3980 MHz and 3450-3550 MHz) to different customers, then service versatility and customer choice are improved, but device compatibility and service reliability deteriorate because user equipment may not be capable of operating in one or more of those frequency ranges
Solution Approach 1:
The system performs preliminary capability assessment by receiving and storing UE capability information indicating supported frequency ranges before service provisioning. The SES uses this pre-collected capability data to determine authorized frequency ranges, preventing compatibility issues before they occur and ensuring reliable service delivery.
Solution Approach 2:
The system assigns different frequency range authorizations to different UEs based on their specific capability profiles. Each UE receives a customized authorization for specific frequency ranges (e.g., some UEs authorized for 3700-3980 MHz, others for 3450-3550 MHz, and some for both), rather than applying a uniform frequency allocation policy to all users.
2Manufacturing precision
If the system dynamically adjusts frequency range authorization based on UE capability and rate plan, then service precision and resource efficiency are improved, but system complexity increases due to the need for capability matrix adjustment and authorization tracking
Solution Approach 1:
The Service Entitlement Server (SES) acts as an intermediary component that centralizes the logic for determining authorized frequency ranges. It receives UE capability information, consults rate plan subscriptions, and outputs authorization decisions. This intermediary architecture manages the complexity by consolidating it in a dedicated component rather than distributing it across multiple system elements.
Solution Approach 2:
The system maintains a dynamic capability matrix that can be adjusted based on changing UE capabilities and rate plan subscriptions. The authorized frequency ranges are not fixed but can be dynamically modified when UE capabilities or subscriptions change, allowing the system to adapt precisely to current conditions while managing complexity through structured data organization.
3Productivity
If the SES authenticates and authorizes frequency ranges based on rate plan subscriptions, then resource allocation efficiency is improved, but processing time and operational complexity increase
Solution Approach 1:
The system performs preliminary authentication of the UE and retrieval of rate plan subscription information before frequency range authorization is needed. By having this data prepared in advance, the actual frequency range determination and authorization process can proceed quickly without time-consuming lookups or validations at the moment of service delivery.
Solution Approach 2:
The SES automatically determines authorized frequency ranges by comparing UE capability information with rate plan subscription data without requiring manual intervention. The system self-authenticates the UE, self-evaluates capability compatibility, and self-issues authorization decisions, eliminating time-consuming manual processing steps.

AI summary
Aspects of the subject disclosure may include, for example, a method that includes receiving, by a processing system, a query from a server regarding a frequency range for use in a communication by user equipment (UE); responding to the query by providing information to the server regarding whether use of the frequency range is authorized; receiving an updated report from the UE, based on the information, regarding capability of the UE to communicate using the frequency range; directing the UE to initiate the communication using a selected frequency range; and dynamically adjusting the selected frequency range. Other embodiments are disclosed.
