Abstract: After a first broadband access server (BAS) receives a connection request of a first terminal, when a quantity of remaining session resources of the first BAS is less than or equal to a first threshold, the first BAS sends the connection request to a second BAS, so that the first terminal accesses a network via the second BAS, wherein the second BAS is determined by the first BAS by using a BAS pool communication protocol.
