<p>The present invention relates to a method and a service node for performing dynamic tracking of a group of mobile terminals. The group of mobile terminals for which dynamic tracking is to be performed is first defined. One of the mobile terminals is identified as the reference point. A maximum distance to be respected between the reference point and the other mobile terminals of the group is then provided. Actual distance between the reference point and the other mobile terminals of the group is measured, and a warning signal is issued if the actual distance of one of the mobile terminals of the group is greater than the provided maximum distance.</p> |
