A method for establishing a self-organized emergency mobile core in a cellular communication network, the cellular communication network having a core element. The method includes the step of storing program code for implementing core network functionality on at least one stationary network element of the cellular communication network allowing to host virtual network functionality. The core network functionality remains inactive when the core element is available. The method includes the steps of detecting an emergency event within the cellular communication network resulting in an unavailability of the core element, and starting operating the core network functionality in order to establish a self-organized emergency mobile core in response to the detected emergency event.

A method for facilitating coordinated multipoint communication providing a plurality of network interface devices for measuring synchronization accuracy in the backhaul network; creating an actual coverage map for the coordinated multipoint communication analyzing the created actual coverage map to determine whether the backhaul network is sufficient for a selected coordinated multipoint technique; if the backhaul network is not sufficient determining one or more key performance indicators creating a conditional coverage map; comparing the actual coverage map with the conditional coverage map; reconfiguring the wireless communication network if the actual coverage map does not match the conditional coverage map.
