Dual-Priority UE EAB Override Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication networks are not optimized for Machine to Machine (M2M) communication, leading to network congestion and operational complexity, with a lack of solutions for configuring dual-priority User Equipment (UE) to facilitate effective M2M services.
Innovation Solution
A method and system that allows an OMA DM server to send overriding indicators to dual-priority UE, enabling it to determine whether to override low priority and/or Extended Access Bar (EAB) settings, thereby managing NAS functional parameters and facilitating the application and promotion of dual-priority UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a mechanism adopting backoff time and Extended Access Bar (EAB) is used to avoid network congestion, then network load is reduced, but MTC UE cannot initiate normal priority requests even when needed
Solution Approach 1:
The patent introduces dynamic priority indication parameters that allow MTC UE to switch between low priority and normal priority modes based on actual service needs. The network can dynamically adjust the priority status of specific UEs through signaling, enabling flexible adaptation between congestion avoidance and service quality requirements.
Solution Approach 2:
The patent changes the priority parameter state of MTC UE by introducing override indication parameters. When the override indicator is set, the UE's priority parameter changes from low to normal, allowing it to bypass EAB restrictions and initiate normal priority requests, thus resolving the contradiction between load reduction and service flexibility.
2Reliability
If existing mobile network is designed mainly for person-to-person communication, then H2H communication is optimized, but M2M and person-machine communication are not optimized sufficiently
Solution Approach 1:
The patent makes the access control mechanism universal by creating a dual-priority system that can serve both traditional H2H communication and M2M communication needs. The same EAB mechanism applies to both UE types, but with the addition of override capabilities that allow MTC UE to access normal priority channels when required, achieving multi-functionality.
Solution Approach 2:
The patent segments the user equipment into different priority categories (normal priority UE and low priority MTC UE) with distinct access control rules. By introducing separate priority indication parameters and override mechanisms for MTC UE, the system creates specialized handling paths while maintaining the overall EAB framework.
3Device complexity
If low priority indicator and EAB indicator are stored in USIM for MTC UE, then access control is simplified, but dual-priority UE configuration is not supported
Solution Approach 1:
The patent nests additional priority control parameters within the existing USIM structure. The override indication parameters are stored alongside the traditional low priority and EAB indicators, creating a layered configuration system where the new parameters work in conjunction with existing ones to enable dual-priority functionality without restructuring the entire USIM architecture.
Solution Approach 2:
The patent pre-configures override indication parameters in the USIM during manufacturing or initial provisioning. This preliminary setup allows dual-priority MTC UE to have the necessary configuration data ready before network access, enabling them to switch between priority modes as needed without requiring complex real-time configuration changes.

AI summary
A method, system and related device for overriding low priority and/or Extended Access Bar (EAB) are disclosed. The method includes the following steps: an Open Mobile Alliance (OMA) Device Management (DM) server sends dual-priority User Equipment (UE) a low priority overriding indicator and/or an EAB overriding indicator; and the dual-priority UE determines whether to override low priority and/or EAB according to the low priority overriding indicator and/or the EAB overriding indicator. The disclosure determines an EAB processing manner of dual-priority UE, implements the NAS functional parameter management for the dual-priority UE, and facilitates the application and promotion of the dual-priority UE.
