Method for determining speed of terminal, and receiver

摘要

The invention relates to a method for determining speed of terminal in a radio system, and to a receiver in a radio system, the receiver comprising means for taking samples from a received signal at given intervals, means for determining a signal instantaneous strength by measuring a signal strength of each sample, and means for calculating a mean strength for a sampled signal within a given time window. For preferably determining the terminal speed the receiver of the invention comprises the means for comparing instantaneous strength values with a calculated mean strength and for calculating how frequently an instantaneous strength moves above or below a mean value within the given time window, and the means for determining an apparatus speed based on the number of transitions.
