Lte Kpi Check [PDF]

he purpose is to check the performance of Network. We have categories of KPI and numbers of KPI of each category. In the Optimization process we have to check the KPI value to monitor and optimize the radio network performance in order to provide better subscriber quality or to achieve better use of installed network resources . Typically KPI can be categorized into following subcategories:'

Accessibility KPI Are used to measure properly of whether services requested by users can be accessed in given condition, also refers to the quality of being available when users needed. eg. user request to access the network, access the voice call, data call, ......

📈 Retainability KPI Are used to measure how the network keep user's possession or able to hold and provide the services for the users

📈 Mobility KPI Are used to measure the performance of network which can handle the movement of users and still retain the service for the user, such as handover,...

📈 Integrity KPI Are used to measure the character or honesty of network to its user, such as what is the throughput, latency which users were served.

📈 Availability KPI Are used to measure the availability of network, suitable or ready for users to use services.

📈 Utilization KPI Are used to measure the utilization of network, whether the network capacity is reached its resource.
