Patent ID: 8339439

Claim:
A system for implementation of videotelephony functionality providing videotelephony communication via a data network, wherein the system comprises radio access means for a radio connection to the data network and for communicating with at least one distant terminal via the data network, and wherein the system further comprises: videotelephony control means coupled to decoding means for decoding of received videotelephony data from a distant terminal, and coupled to encoding means for encoding of videotelephony data to be sent to the distant terminal; coupled to the radio access means, detecting means for detecting an interruption of an actual radio access connection, wherein the detecting means is configured to inform the videotelephony control means about an interruption of the radio access connection; wherein the videotelephony control means is configured, after resumption of the radio access connection, to send a request message to the distant terminal for generation of an independently encoded video frame by the distant terminal for resynchronization of the videotelephony communication at a mobile terminal comprising the system.
