Proximity offloading and service continuity support for mobile communication devices
First Claim
1. A mobile communication device, comprising:
- a processor configured to;
send a first message including a geographic location of the mobile communication device to a server, andreceive, in response to the first message, a second message from the server indicating that a second mobile communication device is within a predetermined range of the mobile communication device; and
a wireless local area network (WLAN) module configured to;
establish a direct wireless communication link with the second mobile communication device in response to the second message,wherein the processor is further configured to;
encapsulate a first packet containing a first Internet Protocol (IP) address used for indirect communication over a network with the second mobile communication device into a second packet containing a second IP address used for direct communication over the direct wireless communication link with the second mobile communication device, to form an encapsulated packet, wherein the second IP address used for direct wireless communication over the direct wireless communication link is generated by the processor; and
transmit the encapsulated packet, via the direct wireless communication link, to the second mobile communication device.

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.

10. A method, comprising:
-
sending, using a processing device of a first mobile communication device, a first message including a geographic location of the first mobile communication device to a server; receiving, using the processing device, in response to the first message, a second message from the server indicating that a second mobile communication device is within a predetermined range of the first mobile communication device; establishing, using the processing device, a direct wireless communication link with the second mobile communication device in response to the second message; encapsulating, using the processing device, a first packet containing a first Internet Protocol (IP) address used for indirect communication over a network with the second mobile communication device into a second packet containing a second IP address used for direct communication over the direct wireless communication link with the second mobile communication device, to form an encapsulated packet, wherein the second IP address used for direct wireless communication over the direct wireless communication link is generated by the processing device; and transmitting the encapsulated packet, via the direct wireless communication link, to the second mobile communication device. - View Dependent Claims (11, 12, 13, 14)
