Disclosed are a message processing method, device and system. The method comprises: an access device establishing at least one tunnel between same and a CGN device; the access device receiving a first data message sent by a first user terminal; the access device acquiring, according to the mapping relationship between a user terminal address and a user identifier, a first user identifier corresponding to the first user terminal, and performing GRE encapsulation on the first data message, so as to obtain a first GRE message, wherein the first GRE message carries the first user identifier; and the access device sending the first GRE message to the CGN device through the at least one tunnel. By means of the embodiment, when a large number of users access a network, the overhead of tunnel resources can be reduced, the configuration process can be simplified, and the system overhead and network resources can be saved. |
