<p>A method and system for accessing network are disclosed in the present invention. The method includes that: terminals in a same group execute random number synchronization (402); when an arbitrary first terminal in the group initiates network access, terminals in the group except the first terminal monitor the access of the first terminal according to the synchronized random number (403); after monitoring that the first terminal accesses network successfully, the terminals in the group except the first terminal initiate network access by using Radio Resource Control (RRC) connection uplink resources which are allocated to the group by the network (404). The technical solution of the present invention can reduce the signaling overhead for establishing signaling connection and data bearing.</p>
