Abstract: Methods are described for dynamically managing device locationing groups. According to some aspects, mobile devices may be tracked on a group basis, e.g., as opposed to being tracking on an individual basis. For example, location information for each of a plurality of mobile devices may be received at a location group server (LGS) and the LGS may determine (e.g., based on the location information) that each of the plurality of devices are in a physical location. One or more location group operations may be triggered by the location group server (e.g., based on determining that each of the plurality of devices are in the physical location) and the LGS may receive a location update from a device of the plurality of mobile devices (e.g., wherein the location update is not received from a remainder of the plurality of mobile devices).

Abstract: Described herein are methods and procedures to enhance the 3GPP system with XRM Server functionality to assist VAL servers with the creation and management of spatial anchors. For example, an XRM server may send a spatial anchor ranging request to one or more other services. The one or more other services may determine ranging distances and orientations between a spatial anchor and a user device and send the ranging distances and orientations to the XRM server. The XRM server may receive the ranging distances and orientations, compare the received ranging distances and orientations with predetermined ranging distance and orientation limits for the spatial anchor, and based on the ranging distances and orientations limits being greater than the received ranging distances and orientations, perform one or more spatial anchor operations.
