METHOD AND APPARATUS FOR DATA TRANSFER

摘要

A method and apparatus for ad hoc addressing and group creation for wireless devices is described. A wireless communication device (100) that has a sensor (124) for sensing the contact (FIG. 2) or close proximity (FIG. 4) of another wireless communication device forms a communication link with the second wireless communication device. The contact or close proximity of the two devices operates to identify the two devices for which a link will be established (FIG. 8). This provides easy addressing of the desired device, and security as the user must initiate physically contacting or bring the device in very close proximity to the other device. Once the link is established data can be transferred, (902, 904) between the two devices. In the simplest embodiment, the two devices are touched together and personal contact information is automatically exchanged. If a plurality of devices are in close proximity or touched together, an ad hoc network can be formed between all the devices. The network would be established for only as long as needed. A group list, called an electronic contact group (FIG. 10) is formed for the immediate establishment of the network or saved for later use.
