Abstract
Systems and methods are provided to facilitate direct wireless communication between mobile communication devices while avoiding the need for mobile communication devices to periodically scan for in-range devices and avoiding unwanted breaks in traffic caused by changes in the source and/or destination IP address of packets. Mobile communication devices periodically update their positions to a server, which can send a notification when a mobile communication device comes within range. Further, mobile communication devices can encapsulate packets with an IP address used for direct wireless communication to facilitate this direct wireless communication without disrupting traffic over a core network.
