Claim:
1. A method of supporting a transfer of a first optical network unit in a source passive optical network to a target passive optical network, wherein the source passive optical network and the target passive optical network share an optical distribution network, and the method comprises the steps of: obtaining, from a plurality of optical line terminals, load information of respective passive optical networks among a plurality of passive optical networks sharing the optical distribution network wherein, selecting the first optical network unit, the source passive optical network and the target passive optical network according to the load information of the respective passive optical networks and a predetermined transfer policy; sending a first transfer message to a target optical line terminal corresponding to the target passive optical network, the first transfer message including first identifier information of the first optical network unit; sending a second transfer message to a source optical line terminal corresponding to the source passive optical network, the second transfer message including second identifier information of the first optical network unit and wavelength information of the target passive optical network, such that, receiving a registration message from the target optical line terminal, based on the performance of the activation and synchronization process.
