COMMUNICATION METHODS, TERMINAL EQUIPMENT, AND ACCESS NETWORK EQUIPMENT

Abstract

The invention relates to a method of communication, a terminal device, and an access network device, and relates to the field of communication engineering, a method for reporting the success of a master cell group (MCG) link failure. This method comprises the following steps: When the terminal device sends the first data unit to the first access network device via a split MCG, the terminal device determines that an MCG link failure has occurred. In addition, the terminal device sends a second data unit to the second access network device via a split sccondary cell group (SCG) channel, so that the second access network device sends a second data unit to the first access network device, wherein the second data unit contains information used to indicate an MCG link failure.
