Message detection method and device

The embodiment of the invention discloses a message detection method and a device. The method comprises the following steps of carrying out association recognition table matching on first matching information in a received message and first matching information in an association recognition table, and outputting protocol information after the successful association recognition table matching when the association recognition table matching is successful, wherein the first matching information in the association recognition table is obtained by extracting contents of a control message for creating a data channel; the first matching information corresponds to a message protocol; and the message protocol is obtained by protocol recognition of the control message. According to the method, when the matching information in the association recognition table is matched, since the matching information in the association recognition table is obtained by extracting the contents of the control message for creating the data channel and corresponds to the protocol obtained after the protocol recognition of the control message, the protocol can be recognized without detecting the contents of the message, and the protocol recognition speed is increased.
