What is OSS KPI ? || What is KPI full form?

OSS (Operations Support System) KPIs (Key Performance Indicators) for a 4G (fourth generation) network are crucial for monitoring and optimizing the performance of the network. These KPIs provide insights into various aspects of network operations, ensuring the network runs efficiently and delivers a quality service to its users. While the specific KPIs may vary depending on the network operator and technology vendor, here are some common KPIs for 4G networks:

Network Availability: This KPI measures the percentage of time the network is available and operational. It's essential for ensuring that the network is up and running when users need it. Call Drop Rate: This KPI indicates the percentage of calls that get dropped or disconnected prematurely. High call drop rates can lead to poor user experience. Handover Success Rate: Handovers are essential for maintaining a seamless connection as a mobile device moves between different cells. This KPI measures the success rate of handovers. Data Throughput: Data throughput KPI measures the average data transfer rate within the network. It helps ensure that users receive the expected data speeds. Latency: Latency is the time it takes for data to travel from the source to the destination. Low latency is crucial for real-time applications like online gaming and video conferencing. Packet Loss Rate: This KPI measures the percentage of data packets lost during transmission. High packet loss can result in reduced data quality and retransmissions. Call Setup Time: This KPI measures the time it takes to set up a voice or video call. Short call setup times contribute to a better user experience.

Coverage and Signal Strength: These KPIs assess the extent of network coverage and the strength of the signal within the coverage area. Weak coverage or low signal strength can lead to connectivity issues. Interference Level: Interference can degrade network performance. Monitoring this KPI helps identify and mitigate sources of interference. Cell Utilization: Cell utilization KPI measures how efficiently the network's cells are being used. Overutilized cells can result in congestion and reduced service quality. Subscriber Data Usage: This KPI tracks the data usage of individual subscribers. It's crucial for understanding user behavior and planning network capacity. Subscriber Churn Rate: Churn rate measures the percentage of subscribers leaving the network. High churn rates can indicate dissatisfaction with network quality. Packet Core Network KPIs: These include KPIs related to the performance of the packet core network, including the mobility management, gateways, and routers. Quality of Service (QoS) Metrics: These metrics measure the quality of service provided to subscribers, including metrics related to voice and data services. Security KPIs: These include KPIs related to network security, such as intrusion detection, firewall performance, and authentication success rates. Energy Efficiency: Monitoring the energy efficiency of the network is essential to reduce operational costs and environmental impact. The specific format for presenting and formatting these KPIs may vary depending on the OSS tools and systems in use by a particular network operator. These KPIs are critical for assessing and improving the performance of a 4G network and ensuring a positive user experience.
