The present invention relates to a terminal, an information inter-cut system and method. In the method, after the terminal receives an information play request signaling sent by an information server, if the terminal itself is performing video share, the terminal will send a video share pause signaling to the other terminal of video share, and will send a request accept signaling to the information server after receiving the response signaling of the other terminal; the information server transmits to the terminal the information data to be played; the terminal plays the received information, and sends a video share restoration signaling to the other terminal to restore the paused video share after the information play is over. The present invention can receive any form of information issued by an operator, without influencing the user performing video share service.

Terminal, information inter-cut system and method

A method for accessing a 3G network includes: a terminal accessing a wireless local area network by adopting a WAPI protocol, and notifying an AAA server of a 3G network through an AP of the wireless local area network that the terminal intends to access the 3G network; the AAA server obtaining identity information of the terminal through the AP, and performing an EAP-TLS negotiation process with the terminal through the AP after determining that the terminal is a subscription terminal of the 3G network according to the identity information; and the terminal accessing the 3G network after finishing the EAP-TLS negotiation process. A system for accessing a 3G network includes an AP of a wireless local area network and an AAA server of a 3G network. The present invention reduces unnecessary processes the message interacting, the certificate verification, the signature verification, and so on and improves the system efficiency.

A method and system for updating and using a digital certificate, and the method comprises: a first terminal establishing a secure link with an access point and using the secure link to send a certificate updating request to the access point, where the certificate updating request includes a digital certificate to be updated which is currently used by the first terminal; and the access point sending the digital certificate to be updated to a local Authentication Service Unit which issues the certificate to be updated; and the local Authentication Service Unit which issues the digital certificate to be updated verifying the digital certificate to be updated, and after the digital certificate is verified to be valid, a local Authentication Service Unit corresponding to the access point generating a new digital certificate of the first terminal and sending the new digital certificate to the first terminal through the access point.

Method and system for updating and using digital certificates

A security service control method and a WLAN terminal are provided, and the method includes: stopping a WPI service between a WLAN terminal and an AP when the WLAN terminal creates a security service of an IP layer and/or a layer above the IP layer, wherein the WPI service comprises: encrypting a data link layer message to be transmitted, and decrypting a received data link layer message. After the WPI service is stopped, when the WLAN terminal cancels the security service of the IP layer and/or the layer above the IP layer, the WLAN terminal completes processes of removing association, association, user authentication and key negotiation in turn with the WLAN AP, and uses a session key obtained through the key negotiation to recover the WPI service. The calculating resources can be saved by using the present invention.

Security service control method and wireless local area network terminal

The present invention discloses a security management method and a security management system for a WAPI terminal accessing an IMS network. The method comprises: an authentication service unit (ASU) sending, under the circumstance that an access point and the WAPI terminal pass the verification of the ASU, a security information request message to a home subscriber server (HSS) (S); the HSS setting security information corresponding to the IMS account information of the WAPI terminal as access layer security after receiving the security information request message from the ASU (S); a proxy-call session control function (P-CSCF) receiving an IMS login request message from the WAPI terminal, inquiring about the security information of the WAPI terminal through the HSS, and allowing the WAPI terminal to execute an IMS service flow under the circumstance that the security information of the WAPI terminal is the access layer security (S).

Security management method and system for WAPI terminal accessing IMS network

A method for pre-authenticating a wireless local area network terminal and a wireless local area network system. The pre-authentication method includes after a current access point (AP) which has set up security association with a station (STA) receiving a pre-authentication start packet sent by the STA, the current AP interacting with a destination AP to verify certificates of the current AP and the destination AP for each other. If a certificate of the destination AP is verified to be valid, the current AP sending key information of the security association set up with the STA by the current AP to the destination AP, and the destination AP saving the key information, the key information including a basic key generated by negotiation between the STA and the current AP.
