How do you ensure the quality of service and user experience in the core network in IMS?

2 Key Performance Indicators

The key performance indicators (KPIs) are essential metrics for measuring the performance and quality of the core network in IMS, such as availability, reliability, capacity, efficiency, and functionality. Among the common KPIs for the core network in IMS are registration success rate, call setup success rate, call drop rate, call completion rate, call duration, and call quality. It is necessary to regularly monitor these KPIs and compare them with baseline or target values to detect any anomalies, trends, or issues in the core network in IMS.

3 Common Issues and Troubleshooting

The core network in IMS can encounter various issues that affect the quality of service and user experience, such as registration failure, call setup failure, call drop, and call quality degradation. To troubleshoot these issues, you need to use the appropriate tools and methods, such as tracing, logging, testing, and alarming. Tracing involves capturing and analyzing the signaling and media messages between the network elements and the users. Logging requires collecting and reviewing the logs and events from the network elements and the users. Testing involves performing tests and simulations to verify the functionality and performance of the network elements and services. Alarming entails setting up alerts and notifications when the KPIs or the network elements exceed predefined thresholds or values.

4 Network Configuration and Optimization

The network configuration and optimization is the process of adjusting and fine-tuning the parameters and settings of the network elements and services to improve the quality of service and user experience in the core network in IMS. This involves planning objectives, requirements, and constraints; designing an optimal architecture, topology, and layout; implementing changes to the network elements; and evaluating the impact and outcome of configuration changes on KPIs and user feedback. To do this effectively, best practices and guidelines should be followed, such as aligning with business goals and customer needs, balancing cost, complexity, and performance, testing and validating changes before and after implementation, and monitoring results to make adjustments as needed.

5 Tips and Best Practices

To ensure the quality of service and user experience in the core network in IMS, you can apply some tips and best practices. This includes keeping up with the latest standards, technologies, and trends; following industry benchmarks and recommendations; adopting a proactive and preventive approach to network maintenance and management; leveraging automation, analytics, and artificial intelligence capabilities; as well as collaborating and communicating with other stakeholders like vendors, partners, regulators, and customers.
