The embodiment of the invention relates to a paging processing method, an information display method, a device and a system. The paging processing method comprises the steps of receiving paging request message which is registered by a called party UE (User equipment) and sent by an MSC (Mobile Switching Center Server); when the called party UE is in the connection state, sending paging notification message to the called party UE, and returning the paging state message of the called party UE to the MSC. According to the embodiment of the invention, after an MME (Mobility Management Entity) receives the paging request message of the MSC, if the called party UE is in the connection state, besides the condition that a CS (Circuit Switching) domain paging notification message is sent to the called party UE, the paging state message returns to the MSC, so that the condition that the called party UE receives the paging notification message is indicated for the MSC, the phenomenon that the MSC terminates the calling process, or the misoperation that the called party UE is paged on one side of the CS domain due to the overlong waiting time during the period that a circuit domain network waits the called party UE to confirm whether CS Fallback executes or not can be avoided, and the paging success rate is increased.
