The present invention discloses a method for messages transmission in a simplified way, UE transmitting the messages to the network through the lower layer, the method includes following steps: if the lower layer indicates the message has been transmitted successfully, then starting timer, otherwise, ending the current procedure; if the UE has received response from the network before the timer expires, stopping the timer; otherwise, ending the current procedure. The method can effectively avoid unnecessary operations, and reduce energy consumption of the UE.
