Application-Layer Measurement Reporting for Air Interface Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-radio dual connectivity architectures, terminal devices face challenges in reporting application layer measurement results efficiently, leading to network air interface congestion and suboptimal user experience optimization.
Innovation Solution
A method is provided for a first access network device to request a terminal device to suspend or resume reporting of application layer measurement results to a second access network device, balancing air interface load and optimizing network operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device reports application layer measurement results to multiple access network devices simultaneously, then comprehensive quality of experience measurement is achieved, but air interface load increases and congestion occurs
Solution Approach 1:
The patent implements dynamic suspension and resumption of measurement result reporting based on real-time air interface load conditions. The terminal device receives suspension indication information from the network side to temporarily stop reporting to the second access network device, and resumption indication information to restart reporting when load conditions improve. This dynamic adjustment resolves the contradiction by adapting the reporting behavior to current network conditions.
Solution Approach 2:
The patent applies different reporting strategies to different access network devices. The terminal device continues reporting to the first access network device while suspending reporting to the second access network device based on load conditions. This localized differentiation allows comprehensive QoE measurement to be maintained through the first node while reducing air interface load by selectively suspending reporting to the overloaded second node.
2Productivity
If the terminal device suspends reporting to the second access network device, then air interface load is reduced, but measurement result collection completeness deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the terminal device receives suspension indication information from the first access network device (which has been notified by the second access network device), processes this feedback to suspend reporting appropriately, and can receive resumption indication information to restore reporting. This feedback loop ensures that measurement result collection remains complete by coordinating suspension actions through the network side rather than uncoordinated local decisions.

AI summary
This application provides an application layer measurement collection method, and a communication apparatus and system. The method includes: A first access network device requests, based on a request from a second access network device, a terminal device to suspend reporting, to the second access network device, measurement results corresponding to all or some of one or more application layer measurement tasks that are configured by the first access network device for the terminal device. According to the method, air interface load balancing of nodes can be supported, to avoid congestion of a network air interface and improve network operation efficiency.
