Abstract: Methods, apparatus, and systems for providing multicast handover are disclosed. In one example aspect, the method includes receiving, by a first radio access node, a multicast flow comprising data packets of a multicast service, determining, by the first radio access node, whether to initiate a handover procedure for a user device from the first radio access node to a second radio access node, replacing, upon determination to initiate the handover procedure, by the first radio access node, a first portion of the data packets with a flow identifier of a unicast flow, and forwarding, by the first radio access node, the data packets of the multicast service including the flow identifier of the unicast flow to the second radio access node.
