    Abstract: The present invention discloses a method and device for processing paging message when Idle State Signalling Reduction (ISR) is active. The method includes the following step: a Mobility Management Entity (MME) determines that a Mobile Switching Center (MSC)/Visited Location Register (VLR) is a default MSC/VLR and the paging message is used for a Short Message Service (SMS), the MME does not send the paging message to a Serving General Packet Radio Service (GPRS) Support Node (SGSN). The present invention can reduce the unnecessary paging signalling in an Evolved Packet System (EPS) and the 2nd Generation (2G)/3rd Generation (3G), therefore avoiding the network resource waste occurred in the interface of the MME and the SGSN, in the air interface of a General Packet Radio Service/Enhanced Data Rate for Global System for Mobile communication Evolution Radio Access Network (GERAN)/Universal Terrestrial Radio Access Network (UTRAN), and in the MSC/VLR.
