Abstract

This application provides an inter-system handover method and a communication apparatus, and may be applied to an inter-system handover scenario. In a handover process, a source access network device may provide a target access network device with an identity of a terminal device. When determining to add the source access network device as a secondary access network device, the target access network device may send, to the source access network device, a request message for adding a secondary access network device that carries the identity of the terminal device.
