<p>A method, system and device for identifying a user terminal in the network. This method causes the user identifier of access layer and of service layer in the network associated, the association principle is that the user terminal address and the domain identifier are used as the user identifier of access layer, and the user terminal is identified by these two information. In addition, this identifying method of domain identifier and application scope may be expanded by setting the corresponding relationship between the domain identifier and the device addresses in the network. This invention scheme causes the exchange between the service layer and the access layer of the network effective, and it causes to inquire about the information of the user terminal according to different service demand. There is no special need to the terminal device, different kinds of terminals may be accessed, the scheme may be realized simply, and there is essentially no signaling expansion demand. The domain identifier expanded may be applied to more complex network scene.</p> |
