1. A method for hotspot detection, the method comprising: computing, by a device, a ratio of a local user density within a first distance zone of a user density map towards a hotspot center point candidate to a local user density within a second distance zone of the user density map towards the same hotspot center point candidate; if the computed ratio exceeds a threshold, assigning, by the device, particular candidate points of the user density map within a certain distance to the hotspot center point candidate to a hotspot, the hotspot representing a concentrated conglomeration of users of the mobile communication network; and detecting, by the device, a center point of the hotspot based on the particular candidate points assigned to the hotspot.
