Abstract: Embodiments of this application provide a communication method, a communications apparatus, and a storage medium. The communication method includes: sending, by a new master network device, a request to an original master network device, to request context information of a terminal device on the original master network device and an original secondary network device; and receiving the context information of the terminal device on the original master network device and the original secondary network device from the original master network device. This application can effectively simplify implementation steps of resuming a multi-connectivity mode by the terminal device, reduce signaling procedures, and shorten a delay, thereby improving network transmission efficiency.
