Abstract
The present invention discloses a method for implement real time data service and a real time data service system. After starting to forward data messages to an accessed user terminal, an access point (AP) of the real time data service system verifies the user terminal, and continues forwarding the data messages to the user terminal after the verification is successful. Therefore, with the method and system of the present invention, when accessing the real time data service system by adopting the way of authentication and key management based on pre-shared key, it is able to authenticate a user before the user obtains a big amount of service data, thereby the accessing security is effectively improved; furthermore, with the method and system of the present invention, it is able to provide free preview service data to the user at first, and after the preview, obtain and verify the WLAN authentication and privacy infrastructure (WAPI) certificate and signature of the user by initiating a signature authentication request to the user, and then start to charge, which is convenient for the user and is favorable for the operators to popularize the real time data service.
