Abstract: Embodiments of this application provide a data transmission method and a host machine, so that when a host machine cannot directly connect to the Internet, a virtual terminal can still connect to a mobile network. This extends an application scope of the virtual terminal. The host machine obtains a first network address of a physical terminal, where the physical terminal has started to establish a connection or has established a connection to the mobile network; and the host machine sets a second network address of the virtual terminal to the first network address, so that the virtual terminal sends data to the mobile network by using the first network address and/or receives, by using the first network address, data sent by the mobile network. The virtual terminal runs on the host machine.

Abstract: A communication method and an apparatus are provided, so that a terminal device can flexibly perform a handover procedure in a multicast service scenario. The method includes: sending, by a source access device, a first message to an access controller, where the first message is used to request to hand over a terminal device to a target access device, and the first message includes a multicast service context of the terminal device; and receiving, by the source access device, a fifth message from the access controller, wherein the fifth message is used to respond to the message used to request to hand over the terminal device to the target access device, and the fifth message comprises indication information indicating whether to forward multicast service data.

Abstract: This disclosure provides a cache data control method and a device, applied to a first edge cache node. The method includes: receiving a data obtaining request sent from a terminal device, where the data obtaining request includes an identification of to-be-requested data; when the first edge cache node does not include the to-be-requested data, determining a target cache node that includes the to-be-requested data in an edge cache node set corresponding to the first edge cache node and a central cache node corresponding to the first edge cache node; and obtaining the to-be-requested data from the target cache node. This disclosure is intended to improve efficiency of feeding back data information to the terminal device.
