Provided are an access method and transmission point. In the embodiments of the present invention, indication information sent by a second transmission point is received by means of a first transmission point and is used for indicating that said second transmission point supports relay functionality, such that said first transmission point is capable of accessing, according to the indication information, the wireless access network on which the second transmission point is located; thus the first transmission point is taken as a relay node and accesses the wireless access network.
