Abstract

In general, the present invention provides in one aspect thereof a device for proximity-based communication between the device and at least a second device. The device preferably includes: a communication unit adapted to communicate between the first device and the second device in a wireless manner; a network layer that includes a communication specification for communicating information between the device and the second device through the communication unit, the network layer being adapted to determine or detect physical proximity between the device and the second device and communicate information regarding detection of physical proximity between the device and the second device or a lack of detection of physical proximity between the device and the second device; a PAN Cell Management layer that receives the physical proximity information from the network layer over time, the PAN Cell Management layer translating the physical proximity detection information received over time into time- and proximity-based events; and an application layer including a memory in which at least one computer application is stored, the PAN Cell Management layer communicating information of occurrence of at least one of the proximity-based events to the computer application so that the computer application can perform a task programmed to be performed on occurrence of the one of the proximity-based events.

3. The device of claim 2 wherein network protocol layer communicates information in packets.

4. The device of claim 1 wherein the PAN Cell Management layer aggregates recurring physical proximity detection information received from the network layer over time to translate the physical proximity detection information into one of the time- and proximity-based events, the one of the time- and proximity-based events being a representation of the proximity of the device in relation to the second device at the time of translation.

5. The device of claim 4 wherein the time- and proximity-based events include an entered device proximity event, a still within device proximity event, a temporarily left device proximity event, a returned to device proximity event, and an exited device proximity event.

6. The device of claim 1 wherein the task performed by the computer application includes communication with a third device.

7. The device of claim 6 wherein the third device is in proximity with the device and the communication with the third device is wireless communication through the communication unit.

8. The device of claim 1 wherein the computer program registers in memory an interest in time- and proximity-based events for at least one other computer program on the second device.

9. The device of claim 1 wherein the communication unit, the network layer, the PAN Cell Management layer and the application layer reside in a single mobile device.
