Virtual User Module for HSDPA Network Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deploying and testing Universal Mobile Telecommunications System (UMTS) networks is inefficient and costly due to the need for a large number of real mobile devices to simulate warranted capacity, leading to high expenses and variability in test results.
Innovation Solution
Generating virtual users within the High Speed Downlink Packet Access (HSDPA) network using a testing software module that allocates resources and simulates traffic and feedback, allowing the network to operate as if the virtual users were real, thereby optimizing network performance without the need for physical devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of real mobile devices are used to simulate warranted capacity, then the network can be tested under realistic load conditions, but the cost and complexity of the test increases significantly
Solution Approach 1:
The patent creates virtual users that copy the behavior and characteristics of real mobile devices. These virtual users simulate traffic patterns, channel quality indicators, and user movements without requiring physical devices. The virtual user module generates synthetic load conditions that replicate real network usage scenarios, thereby reducing the need for numerous physical test devices while maintaining test validity.
Solution Approach 2:
The patent introduces a virtual user module as an intermediary between the test controller and the network under test. This module acts as a mediator that generates virtual traffic and simulates user behavior, eliminating the need for direct interaction with numerous physical mobile devices. The intermediary layer simplifies the test architecture by consolidating multiple device functions into a single software-based virtual user system.
2Quantity of substance
If many real mobile devices are deployed to reach warranted capacity, then the network can be adequately loaded for testing, but the expense of purchasing and managing devices increases
Solution Approach 1:
The patent creates virtual users that copy the behavior and characteristics of real mobile devices. These virtual users simulate traffic patterns, channel quality indicators, and user movements without requiring physical devices. The virtual user module generates synthetic load conditions that replicate real network usage scenarios, thereby reducing the need for numerous physical test devices while maintaining test validity.
Solution Approach 2:
The patent replaces expensive physical mobile devices with inexpensive virtual user software instances. These virtual users can be created, modified, and destroyed at will without the costs associated with purchasing, maintaining, and logistics of physical devices. The virtualization approach transforms a high-cost physical resource model into a low-cost software-based model.
3Quantity of substance
If real mobile devices are used to generate warranted capacity, then the network can be tested under load, but the introduction of human operators carrying devices introduces variability and requires longer measurement periods
Solution Approach 1:
The patent enables virtual users to autonomously generate and manage their own traffic patterns, channel quality indicators, and movement behaviors without human intervention. The virtual user module automatically simulates realistic user actions such as data transmission, signal variation, and location changes, eliminating the need for human operators to physically carry and maneuver devices during tests.
Solution Approach 2:
The patent introduces a virtual user module as an intermediary between the test controller and the network under test. This module acts as a mediator that generates virtual traffic and simulates user behavior, eliminating the need for direct interaction with numerous physical mobile devices. The intermediary layer simplifies the test architecture by consolidating multiple device functions into a single software-based virtual user system.
4Quantity of substance
If a large number of physical mobile devices are deployed for testing, then the warranted capacity can be achieved, but the logistics of managing and controlling these devices becomes uncontrolled and complex
Solution Approach 1:
The patent creates virtual users that copy the behavior and characteristics of real mobile devices. These virtual users simulate traffic patterns, channel quality indicators, and user movements without requiring physical devices. The virtual user module generates synthetic load conditions that replicate real network usage scenarios, thereby reducing the need for numerous physical test devices while maintaining test validity.
Solution Approach 2:
The patent creates a universal virtual user module that can simulate multiple user behaviors and traffic patterns through a single software component. This multi-functional module can generate various types of traffic (voice, data, video), simulate different user mobility patterns, and adapt to various network conditions, replacing the need for multiple specialized physical test devices and their associated management procedures.

AI summary
Disclosed is a system and method for testing mobile communications in a High Speed Downlink Packet Access (HSDPA) mobile communications network by generating one or more virtual users. Specifically, a high speed downlink shared channel is scheduled for a user (e.g., a real user or a virtual user) in a plurality of users. One or more network resources are then allocated by a virtual user executable module to the high speed downlink shared channel for a virtual user in the plurality of users.
