The present disclosure provides a method for establishing a connection by a terminal, a second node, a first terminal, and a second terminal. The method includes: determining, by a second node, whether a currently connected first terminal needs to establish a connection to a first node, and if a determining result is yes, obtaining a pre-stored first access parameter corresponding to the first node, the first terminal currently connects to the second node, the first access parameter is obtained by means of statistics collection according to a second access parameter reported by a second terminal, and the second terminal is a terminal connecting to the first node; and delivering, by the second node, the first access parameter to the first terminal. According to the present disclosure, a delay generated during cell handover of a terminal can be reduced, and user experience is improved.
