Publication number: 20050138128Abstract: A method for transferring an instant messaging and presence (IMP) session from a source device (101) to a target device (103) includes the steps of registering (130) the target device with an IMP server (105), sending (150, 152) historical IMP session information from the source device to the target device, and subscribing (170) the target device to the IMP server. The target device (103) initiates the transfer of historical IMP session information (thus, we refer to it as a “grab” or “grab transfer”), and the target device (103) may optionally instruct the source device (101) to de-register (160) from the IMP server (105). Related methods for the target device and the source device are disclosed as well as an electronic device operable to be either a source device or a target device.Type: ApplicationFiled: December 23, 2003Publication date: June 23, 2005Inventors: Uri Baniel, Lang Xu
