摘要： A method and a device for identifying circuit switched fallback (CSFB) user equipment. The method includes the following steps: determining identification parameters of the CSFB user equipment and common user equipment, where the identification parameter of the CSFB user equipment is different from the identification parameter of the common user equipment; receiving a channel request message sent by user equipment; and identifying the CSFB user equipment according to content of the channel request message and the identification parameter of the CSFB user equipment, where the common user equipment refers to user equipment except the CSFB user equipment. According to the present invention, after receiving a channel request message, a device on a network side can rapidly identify, according to content of the channel request message, that user equipment is CSFB user equipment, so that after the CSFB user equipment is identified, a signaling exchange process between the CSFB user equipment and the network side can be simplified, thereby reducing an overall delay caused when the CSFB user equipment accesses an circuit switched network.
