Abstract
A session establishment method, a data transmission method, and a related apparatus are provided. A first device receives a first message sent by a second device. The first device establishes a first session with a third device based on the first message. The first message carries a first identifier and a second identifier, and the second identifier indicates information about a group to which the first identifier belongs. A fourth device is determined based on the second identifier. According to the application, the efficiency on determining the fourth device is improved, thereby improving data transmission efficiency.
