Systems, methods, and devices enable group associations based on network determined location information. The various embodiments enable the ad-hoc creation of mobile device groups based on network determined locations. In an embodiment, a server may determine the location of a mobile device and based on the mobile device being located in a pairing zone may add the mobile device to a group. In an embodiment, the server may add the mobile device to the group following the occurrence of a trigger event, such as the mobile device pausing in a given pairing zone for a period of time. In an embodiment, the server may identify that mobile devices are located within a pairing zone and may add all the mobile devices in the pairing zone to the same group.
