  • Patent number: 9288730
    Abstract: A mobile relay node having communication sessions with a plurality of wireless mobile device (UEs) and a communication link to a source base station via a first communication link is located within a moving vehicle. As the vehicle moves from the coverage area of the source base station to the coverage area of a target base station, the relay node performs a hand off process that initiates a second communication link with the target while maintaining and continuing to relay communications between the UEs and the source. Once the second communication link is active, the relay node switches UE traffic from the source base station to the target base station over the second communication link, and then releases the first communication link.
