Abstract: A message relay arrangement is described. A first terminal sends a first message to a second terminal, where the first message that instructs the second terminal to determine a type of the second terminal based on the first message. Based on the terminal type, the second terminal operating as the first-type terminal sends first measurement information; or operating as the second-type terminal receives first measurement information sent by a first-type terminal, determines quality of a first link between the first-type terminal and the second-type terminal, and sends the quality of the first link to the first terminal. The first terminal receives the quality of the first link sent by the second-type terminal. The first terminal determines a mapping relationship between the first-type terminal and the second-type terminal based on the quality of the first link. The first terminal sends the mapping relationship to terminals corresponding to the mapping relationship.
