Mobile Station Application Status Reporting for Cellular Network Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular radio systems lack efficient methods to monitor and report the performance of packet-switched services, such as Music Download and Mobile-TV, making it difficult for operators to identify and address service disruptions and optimize network resources.
Innovation Solution
A method and device that enable mobile stations to send status messages to the cellular radio system, including parameters like application data volume and user experience, allowing operators to monitor Key Performance Indicators (KPIs) and perform cell tuning, with the message structure comprising fields for application type, timing, issues, location, and payload, transmitted via the GPRS signaling layer to the IP Multimedia Subsystem (IMS) node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drive tests are performed to collect radio system performance data, then network planning and resource management are improved, but cost and time consumption increase
Solution Approach 1:
The mobile station automatically generates and transmits performance indication messages to the network without requiring manual intervention from operators or third parties. The system enables users to self-report their experience quality, eliminating the need for expensive and time-consuming drive tests while providing continuous network performance data.
Solution Approach 2:
The invention implements a feedback mechanism where mobile stations continuously report their service experience quality to the network operator. This feedback loop allows the operator to receive real-time information about packet-switched service performance from actual users, enabling proactive network optimization without requiring manual measurement campaigns.
2Reliability
If drive tests are used to monitor service performance, then network coverage assessment is improved, but operational complexity increases
Solution Approach 1:
The mobile station autonomously monitors its own service experience and generates performance indication messages without requiring external testing equipment or manual operations. This self-service approach simplifies operational complexity while maintaining comprehensive service level monitoring across the network.
Solution Approach 2:
The performance indication message structure is designed to be universally applicable across different packet-switched services and network conditions. A single standardized message format enables the system to monitor various service types (music download, mobile TV, MBMS) and report different quality parameters, eliminating the need for multiple specialized monitoring systems.
3Productivity
If the network collects detailed application performance data, then resource optimization is improved, but information processing requirements increase
Solution Approach 1:
The invention extracts only the essential performance information needed for network optimization into structured messages. By selectively capturing key parameters (service type, quality indicators, timing data) rather than transmitting complete application data streams, the system reduces data processing requirements while maintaining sufficient information for effective resource allocation and network planning.
Solution Approach 2:
The system transforms complex application performance data into standardized parameters and metrics that are easier to process and analyze. The performance indication messages convert detailed service experience information into structured fields (service type, quality level, timing), simplifying data processing while preserving the essential information needed for optimization decisions.
Data Source
AI summary
In a cellular radio system a message is transmitted in the uplink from a mobile station running an application to the cellular radio system informing the radio system of the status of the application thereby enabling the operator of the radio system to collect such data for use in optimizing the planning of the radio system or as an input parameter when detecting and trouble shooting problems in the radio system network.
