Abstract: A wireless User Equipment (UE) associates video session capabilities with relay identifiers. The UE wirelessly establishes a video session using a network address. The UE receives a handover command and wirelessly attaches to a wireless relay. The UE receives a new network address and a relay identifier that identifies the wireless relay from the wireless relay. The UE determines if the wireless relay supports the video session mobility based on the received relay identifier and the association of the video session capabilities with the relay identifiers. The UE continues the video session using the initial network address when the wireless relay supports the video session mobility. The UE re-establishes the video session using the new network address when the wireless relay does not support the video session mobility.
