Local Overload Compensation through LTE System Level Interference Control in Realistic Scenarios

System level analytical models and simulations usually use analytical propagation models for estimating received signal power. These propagation models are typically based on statistical properties. Consequently, they are very well suited for general assessment of communication technologies and protocols. However, their universality lets them produce unrealistic results in situations where the concrete assessment of network situations is needed. This type of assessment is particularly useful for network self-healing mechanisms, e.g relay positioning. For this purpose, ray tracing based approaches provide detailed assessment of real network configurations. Ray tracing can thus be used for replacing the path loss estimating part in analytical system level Long Term Evolution (LTE) models or simulations. In this work, a novel combination of ray tracing and an existing analytical interference-aware downlink model was made possible through extension of the model. It is shown at the example of a realistic scenario that system level interference control can be used to enhance the overall user satisfaction of the LTE system. This is done through prevention of a full interference situation by throttling non-premium users.
