Patent ID: 8792910

Claim:
A method in a first service-related node for providing a deferred distance notification for at least two user devices, said method comprising the steps of: receiving from a second service-related node, a request for a deferred distance notification for the at least two user devices, wherein the request comprises user device identification data for the at least two user devices and a plurality of distance-related event criteria for the at least two user devices; sending to a third service-related node, a request for the location of the at least two user devices; receiving from the third service-related node, location data of the at least two user devices; determining geographical distances between the at least two user devices or between each user device and a reference device based on the location data of the at least two user devices and a known location of the reference device; monitoring fulfillment of the plurality of distance-related event criteria for the at least two user devices based on the determined geographical distances between the at least two user devices or between each user device and a reference device, wherein the distance-related event criteria include: (a) the geographical distance between at least one of the user devices and the reference device is less than a first defined geographical distance; (b) the geographical distance between at least one of the user devices and the reference device is greater than the first defined geographical distance; (c) the geographical distance between any two user devices of a plurality of user devices is less than a second defined geographical distance; and (d) the geographical distance between any two user devices of the plurality of user devices is greater than the second defined geographical distance; triggering the deferred distance notification when an event criterion of the plurality of distance-related event criteria is fulfilled; and sending the triggered deferred distance notification of the user device distance event to the second service node.
