Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for selecting serving nodes for access, where the method includes: obtaining reference signal received parameters of at least two nodes; selecting a downlink serving node from the at least two nodes according to the reference signal received parameter of each node; and sending an uplink signal, so that the downlink serving node selects an uplink serving node from the at least two nodes according to the uplink signal; or, selecting an uplink serving node from the at least two nodes according to the reference signal received parameter of each node, and sending an uplink signal. In the embodiments of the present invention, a user equipment selects a downlink serving node from at least two nodes according to the reference signal received parameter of each node; then the user equipment sends an uplink signal.
