CSSR stands for Call Setup Success Rate, which is a key performance indicator (KPI) in cellular networks. It measures the success rate of call connections within a network, including the initial setup and connection to the network service. The significance of CSSR lies in its ability to reflect the network’s performance and reliability from the user’s perspective. A high CSSR indicates a reliable network with a good user experience, as most calls are successfully connected without issues. Conversely, a low CSSR can point to potential problems in the network that may need to be addressed to improve service quality.
The Call Setup Success Rate (CSSR) is typically measured from the Mobile Switching Center (MSC) in a cellular network. The MSC is responsible for call handling and connection setup in the network’s core. It interfaces with various other nodes, such as the Base Transceiver Station (BTS) and the Base Station Controller (BSC), to facilitate the process of call setup and ensure successful call connections. By measuring CSSR at the MSC, network operators can assess the performance of the core network in handling call setups.
To monitor and track the Call Setup Success Rate (CSSR) for your network, you can use network monitoring tools that offer performance metrics tracking. Here’s a general approach:
1. Choose a Network Monitoring Tool: Select a tool that supports Key Performance Indicators (KPIs) relevant to telecom networks, including CSSR. Some tools offer free trials to test their capabilities.
2. Configure the Tool: Set up the tool to connect with your network elements using protocols like SNMP, which is commonly used for collecting information from various network devices.
3. Set KPI Thresholds: Define the thresholds for CSSR that align with your network’s performance goals.
4. Enable Alerts: Configure alerts to notify you when the CSSR drops below the defined threshold, indicating potential issues.
5. Regular Reporting: Schedule regular reports to analyze trends and identify areas for improvement.
6. Analyze Data: Use the data collected by the tool to make informed decisions about network management and optimization.
Remember, the specific steps may vary depending on the tool you choose. It’s essential to ensure that the tool you select can accurately track and report on CSSR and other relevant KPIs for your network.
