Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in testing user equipment (UE) for application-specific congestion control and unattended/background data traffic, as real applications exhibit non-deterministic and unpredictable behavior, making conformance testing difficult, especially due to operating system complexities.
Innovation Solution
Introducing new test loop modes F and G in user equipment (UE) and system simulators to configure and test application-specific congestion control, allowing for controlled transmission and loopback of packets based on configured data characteristics, such as ACDC categories, packet types, and timing, to simulate and verify UE behavior under specific conditions.

Engineering Contradiction Analysis
1Reliability
If real applications are used for testing, then the testing reflects actual system behavior, but the non-deterministic and unpredictable behavior makes conformance testing difficult
Solution Approach 1:
The patent creates simplified test applications that copy the essential characteristics of real applications (data transmission patterns, packet sizes, timing) without including their non-deterministic complexity. These test applications replicate only the necessary behavior for conformance testing, eliminating OS-level unpredictability while maintaining testing relevance.
Solution Approach 2:
The patent extracts only the essential testing-relevant characteristics from real applications (data patterns, transmission timing, packet structures) and separates them from the complex operating system environment. This extraction creates a controlled test scenario that isolates the specific functionality being tested from unrelated system variability.
2Adaptability or versatility
If operating system functionalities are included in testing, then comprehensive system behavior is tested, but it creates additional difficulties for deterministic testing
Solution Approach 1:
The patent segments the testing process into distinct layers: a controlled test application layer that provides deterministic behavior, and a separate system under test layer. This segmentation allows the test application to maintain precise control over test conditions while still interacting with the full system, including OS functionalities, thereby preserving both coverage and determinism.
Solution Approach 2:
The patent performs preliminary configuration of test applications with predetermined data patterns, timing parameters, and transmission characteristics before actual testing begins. This preliminary setup ensures that all test inputs are deterministic and known in advance, allowing comprehensive system testing while maintaining measurement precision through pre-planned test scenarios.

AI summary
Various communication systems may benefit from appropriate testing, which ensures that a user equipment under a test is implemented according to the specifications. For example, systems that include application specific data transmission may benefit from special test functions for such transmission. A method can include receiving, at a user equipment, a configuration from a system simulator. The user equipment can generate data for transmission according to the received configuration. The method can also include user equipment transmission based on a loop-back, in which the system simulator transmits packets to the user equipment and the user equipment loops the packets back according to configuration.
