Abstract
A communication system having a controlled device (105), for which an abstract representation (AR) (107) is provided as interface on a controlling device (103). When the quality of the connection between the controlling device (103) and the controlled device (105) drops below a predetermined level, or if some similar criterion is met, the system selects a second controlling device (104) which is better suited for controlling the controlled device (105) and generates a migration event to indicate this. The first controlling device (103) transfers control over the controlled device (106) to the second controlling device when it receives said migration event. This can be done by uploading the AR (107) to the second controlling device (105), possibly supplemented with the current state of the AR (107) to perform a fully transparent transfer.
