Abstract
A communication method and apparatus are provided, to support data transmission over a multi-access session through multiple 3GPP paths or multiple non-3GPP paths. Access technologies corresponding to a first transmission path and a second transmission path in the multi-access session are of a same access type. A session management device sends, to a mobility management device, tunnel information and access technology information that correspond to the transmission paths, where the access technology is used to determine an access network device. The mobility management device determines the access network device based on the access technology information, and sends the tunnel information to the access network device. In this application, the session management device sends, to the mobility management device, the access technology information which is a finer granularity than an access type, and the mobility management device can accurately identify a corresponding access network device based on the access technology information.
