A method by a coordination node is provided for controlling communications between Li-Fi APs and UEs. The method includes receiving peer connectivity reports from Li-Fi APs which identify Li-Fi APs having at least partially overlapping coverage areas, and developing a handover pathway data structure, based on the peer connectivity reports, that identifies Li-Fi APs that can receive communication handover from other identified Li-Fi APs. The method further includes determining an identifier of a first Li-Fi AP providing Li-Fi communication service for a UE, and accessing the handover pathway data structure using the identifier of the first Li-Fi AP to determine an identifier of a second Li-Fi AP to which handover from the first Li-Fi AP can be performed. The method then initiates handover of the Li-Fi communication service for the UE from the first Li-Fi AP to the second Li-Fi AP.
