1. A method of supporting virtual machine (VM) migration between a first wireless transmit/receive unit (WTRU) and a second WTRU via a 5GLAN, wherein the first WTRU is a host of a VM and the second WTRU connects to the 5GLAN, the method comprising the second WTRU:
receiving the VM migrated from the first WTRU, wherein a tenant system interface (TSI) ID is associated with the VM;
sending a PDU session request message to a network node of the 5GLAN, the PDU session request message comprising the TSI ID, a WTRU ID, a 5GLAN network ID, an inner address, a hot migration flag, and a TSI state; and
receiving a PDU session response message from the network node, wherein the PDU session response message includes an indication of an establishment of a PDU session, for use by the VM, between the second WTRU and the 5GLAN and includes the TSI ID, the WTRU ID, the 5GLAN network ID, the inner address the hot migration flag, and the TSI state.
