Disclosed are a signaling sending method and apparatus. The method comprises: receiving and decoding Msg3 from a user terminal, the Msg3 carrying non-access layer signaling; determining whether the Msg3 is a link establishment or re-establishment request; and when a determining result is No, sending the non-access layer signaling to a core network. Embodiments of the present invention solve a problem that a terminal in a cluster system cannot send the non-access layer signaling to the network when the terminal is in a non-connected state, so that a method for sending non-access layer signaling in a non-connected state is provided, thereby improving system efficiency.
