UE Segregation Server RAN Feature Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack the ability to selectively disable radio access network (RAN) features for erroneous user devices, leading to misuse of network resources and decreased throughput, as existing solutions cannot differentiate between problematic and non-problematic devices without affecting all users in a given area.
Innovation Solution
A method and system that utilize a UE segregation server to identify erroneous user equipment based on Type Allocation Code (TAC) information, modify their capability messages, and disable specific RAN features to conserve network resources and improve key performance indicators (KPIs) by comparing TAC information from user equipment with a database of erroneous devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RAN features are disabled for all users in a given area, then network performance is improved, but user experience deteriorates for non-problematic devices
Solution Approach 1:
The patent segments users into two distinct groups: erroneous users identified by matching TAC information against a database, and non-erroneous users. This segmentation allows differential treatment where RAN features are selectively disabled only for erroneous users while remaining enabled for normal users, thus improving network performance without degrading user experience for legitimate devices.
Solution Approach 2:
The patent applies local quality by modifying RAN features at the individual user level rather than applying a blanket restriction to all users in an area. The UE capability information is modified specifically for identified erroneous UEs, allowing the network to apply different feature configurations to different users based on their error characteristics, thereby targeting the problem locally without affecting other users.
2Ease of operation
If RAN features remain enabled for erroneous user devices, then user experience is maintained, but network resources are misused and throughput decreases
Solution Approach 1:
The patent extracts the problematic element (erroneous user behavior) from the overall user population by identifying devices with matching TAC information in the erroneous database. Once extracted and identified, the system modifies the UE capability information for these specific devices to disable problematic RAN features, thereby removing the source of resource misuse and throughput degradation while leaving other users unaffected.
3Loss of energy
If selective disabling of RAN features is implemented, then network resource efficiency is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism (TAC information matching system with erroneous device database) that mediates between the network and user devices. This intermediary layer handles the complexity of identification and selective feature modification, using the MME to intercept and modify UE capability information based on TAC matches, thereby managing system complexity in a centralized manner rather than distributing it across the network infrastructure.
Data Source
AI summary
A system and method to reduce misuse of radio resources, by modifying radio access network (RAN) features of user devices. The UE segregation server unit [302] as disclosed in the present disclosure identifies one or more UE required to be modified due to which network KPI's are getting degraded, based on an analysis performed by a Network Performance Unit [304]. Further, the UE segregation server unit [302] updates/modifies a UE Capability Indication message to disable certain radio capabilities causing some malfunction in the network based on identification of one or more UEs as erroneous UE based on a successful comparison of the at least one TAC information present in the UE Capability Indication message with at least one TAC information of the identified one or more UE that are required to be modified. This disclosure provides improved throughput for network subscriptions in user devices by saving network resources.
