Abstract
A first UE sending via a sidelink messages to second UE(s) indicating the first UE is changing to a different network access node and therefore might be changing a synchronization source, which the second UE(s) use to maintain a sidelink communication between the first and second UEs. The first UE performs a handover process from a first network access node in the first wireless network to the different network access node in the second wireless network. The second wireless network uses the second synchronization source. The first UE attempts to synchronize the second UE(s) to the second synchronization source. The second UE, and first and second networks may interoperate to effectuate this process. Methods, apparatus, software, and computer program products are disclosed.
