20140245410 | METHOD AND SYSTEM FOR AUTHENTICATING A NETWORK NODE IN A UAM-BASED WLAN NETWORK - The invention relates to a method and system for authenticating a mobile network node in a Wireless Local Area Network, wherein the mobile network node requests access to the WLAN at an access point. Within a closed first network region, before authentication all network protocol layers up to the Layer 3 protocol layer (L3) are set up. An authenticator based on Extensible Authentication Protocol (EAP) is generated on the Web server as captive portal and the Layer 3 protocol layer between the authenticator and the mobile network node comprising an EAP peer is extended bidirectionally by means of a defined bit sequence. In case of an access request, the Web server transmits an authentication stimulus to the mobile node by encoding an EAP message request and transmitting it in the Layer 3 protocol layer by means of the defined bit sequence. The mobile node decodes the EAP message request and transmits, in the Layer 3 protocol layer, by means of the defined bit sequence, an encoded EAP response message to the authenticator, the EAP response message comprises authentication data of the mobile network node. The Web server decodes the EAP response message from the bit sequence, transmits it to an AAA server including an EAP server by means of an authentication inquiry. On the basis of an authentication response by the AAA Server, access is enabled to a second network region for use by the mobile network node by means of a Network Access Server. | 08-28-2014 |
20120282894 | SWITCHING SYSTEM AND CORRESPONDING METHOD FOR UNICAST OR MULTICAST END-TO-END DATA AND/OR MULTIMEDIA STREAM TRANSMISSIONS BETWEEN NETWORK NODES - A method for setting up a data link including requesting an identity of an IP network node by a registration module, transmitting an International Mobile Subscriber Identity (IMSI) stored on a Subscriber Identity Module (SIM) card of the IP network node to the registration module, storing the received IMSI in a user database of the registration module, complementing an IP data channel to form signal and data channels of a GSM network by a signaling gateway module, using the complemented IP data channel as a basis for generating the necessary SS7/MAP functions for authenticating the IP network node, authenticating the IP network node by using the IMSI of the SIM card of the IP network node, receiving an entry in the user database of the registration module upon successful authentication, and setting up a data link to at least some of the network nodes. | 11-08-2012 |
