AT Command Pausing for UE Measurement Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face inefficiencies in managing Quality of Experience (QoE) reports due to the inability to temporarily pause and resume application-level measurement information from user equipment (UE) without stopping and restarting the measurement processes, which is inefficient for brief pauses required during network overload conditions.
Innovation Solution
The implementation of Attention (AT) commands and unsolicited result codes between a modem processor and an application processor in UE allows for temporary pausing and resuming of application-level measurement information transmission in response to network commands, enabling efficient management of QoE reports by configuring the modem to send unsolicited result codes indicating pause or resume instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continuously sends application-level measurement information to the network element, then the network can maintain real-time performance monitoring, but the network becomes congested during overload conditions
Solution Approach 1:
The patent implements dynamic pause/resume functionality where the UE can temporarily suspend measurement reporting in response to network overload conditions and resume when conditions improve. This is achieved through pause commands and resume commands exchanged between the network element and UE, allowing the system to adapt its reporting behavior dynamically based on network status, thereby resolving the contradiction between continuous monitoring and network congestion.
2Object-generated harmful factors
If the UE pauses measurement reporting to alleviate network congestion, then network load is reduced, but the measurement process must be restarted to resume reporting
Solution Approach 1:
The patent ensures continuity of measurement gathering by maintaining the measurement process during pause periods. The UE continues to gather application-level measurement information even when reporting is paused, and upon receiving a resume command, the measurement process continues without requiring restart. This is achieved through the resume command mechanism that restores the reporting function while preserving the ongoing measurement context, eliminating the need to restart measurement processes.
3Loss of energy
If the network element sends pause commands to reduce QoE reports, then network resources are conserved, but the UE cannot distinguish between different application services
Solution Approach 1:
The patent segments the pause/resume functionality at the application service level by including service identifiers in the pause commands and resume commands. This allows the network element to selectively pause reporting for specific application services while maintaining reporting for other services. The UE uses these service-specific identifiers to differentiate between applications and applies pause/resume logic accordingly, enabling granular control that conserves network resources while preserving adaptability across different service types.
Data Source
AI summary
Various embodiments of methods of managing data measurement reporting may include sending from an application processor of a user equipment (UE) to a modem of the UE an attention (AT) command to configure the modem to send an unsolicited result code in response to receiving a pause command or a resume command related to sending of application level measurement information being gathered by the UE, receiving a pause command from a network element while sending of application level measurement information being gathered by the UE to the network element, sending from the modem to the application processor an unsolicited result code including a pause indication or instruction to temporarily pause sending of the application level measurement information in response to the received pause command and the AT command, and pausing sending of the application level measurement information by the modem in response to the pause command.
