摘要： A wireless Local Area Network (LAN 11) capable of providing “enterprise guest” hosting includes at least one an e-open wireless LAN access point (15) that provides access to both guests and local users. Upon receipt of a request for access, the access point forwards the request to an authentication proxy. The authentication proxy then authenticates the party requesting access in accordance with that party's status (that is, whether the party is a local user or guest). Upon successful authentication, the network routes the traffic from a local user differently as compared to that for a guest. For example traffic from guests goes to gateway for receipt in an external network such as the Internet, whereas traffic from the local user goes to a local network, e.g., a corporate intranet. In this way, the Wireless LAN 11, after ascertaining the status of the party requesting access, can limit guest traffic according to the guest access policy.

摘要： An access arrangement ( 11 ) provides secure access by at least one mobile communications device (12 1 -12 3 ) by first authenticating the device itself, and thereafter authenticating the traffic therefrom. To authenticate the traffic from the mobile communications device, an authentication server ( 24 ) associated with the access arrangement ( 11 ) establishes a Wired Equivalent Privacy (WEP) encryption key for both the access arrangement and the mobile communications device. The authentication server provides the WEP encryption key to the device in connection with a command to cause the device to execute a resident ActiveX control to encrypt traffic with the WEP encryption key. Utilizing the Active X control within the mobile communications device to encrypt traffic with the WEP encryption key provides a simple, easy-to-implement method to achieve secure access.

摘要： Secure access by a mobile wireless terminal of a wireless telephony network is achieved by having a Home Location Register store the terminal's temporary and permanent identities. Upon accessing the network following initial registration, the terminal sends a temporary identity to a Serving GPRS Support Node (SGSN). If no serving node in the network knows the terminal, the terminal need not sent its permanent identity in clear as was previously required. Rather, the serving node need only query the HLR since the HLR can map the terminal's temporary identity to its permanent identity. In this way, the permanent identity of the mobile wireless terminal remains secure.

摘要： A mobile wireless terminal, upon transitioning from a wireless telephony network to a wireless Local Area Network (LAN), seeks identification by sending the same identity information used for identification in the wireless telephony network. Upon receipt of the identity information, a wireless LAN Access Server in the wireless telephony network identifies a Serving General Packet Radio Service Serving Node (SGSN) that had last served the wireless terminal in the wireless telephony network prior to transition. The wireless LAN Access Server forwards the identity information to the SGSN, which, in turn, provides an identification response for validating the terminal.

摘要： "autenticação, autorização, contabilidade transitiva na inter-operação entre redes de acesso". um método e um sistema para permitir um dispositivo de usuário (240) que já foi autenticado por uma primeira rede de comunicações para ganhar acesso a uma segunda rede de comunicações sem sofrer autenticação pela segunda rede de comunicações. a primeira rede de comunicações e a segunda rede de comunicações têm uma relação de confiança pré-estabelecida entre elas. um pacote é recebido do dispositivo de usuário (240) que inclui uma chave pública do dispositivo de usuário, pela segunda rede por meio da primeira rede (210) . uma chave de sessão é enviada da segunda rede (220) para o dispositivo de usuário (240), por meio da primeira rede (210), quando um endereço de protocolo de internet (ip) fonte associado ao pacote cai dentro de uma faixa alocada na primeira rede (210). a chave de sessão é criptografada com a chave pública do dispositivo de usuário. o dispositivo de usuário descriptografa a chave de sessão usando uma chave privada e usa a chave de sessão depois disso para acessar a segunda rede (220). também um mapeamento é gerado para correlatar a identidade do dispositivo de usuário (240) com a chave de sessão de modo que os dados de uso relacionados ao dispositivo de usuário (240) são gerados pela segunda rede de comunicações e transmitidos à primeira rede de comunicações, que gera informação de contabilidade indicativo do acesso do dispositivo de usuário (240) da segunda rede de comunicações.

摘要： THE INVENTION PROVIDES AN APPARATUS AND A METHOD FOR IMPROVING THE CONTROL OF ACCESS BY A TERMINAL DEVICE IN A WLAN (115) ENVIRONMENT HAVING AN ACCESS POINT (130) FOR DETERMINING WHETHER THE DEVICE UTILIZES AN IEEE 802.1 x PROTOCOL BY THE ACCESS POINT (130) COMMUNICATING TO THE DEVICE, A PACKET, WHEREBY IF THE DEVICE UTILIZES A IEEE 802.1x PROTOCOL THE DEVICE APPROPRIATELY RESPONDS AND OTHERWISE THE ACCESS POINT (130) DETERMINES THAT THE TERMINAL DEVICE PROTOCOL DOES NOT EMPLOY A IEEE 802.1x PROTOCOL AND SELECTS AN AUTHENTICATION MECHANISM COMPATIBLE WITH THE TERMINAL DEVICE. IF THE DEVICE IS NOT AN IEEE 802.1x CLIENTS, AN IP PACKET FILTERING IS CONFIGURED TO REDIRECT A USER HTTP REQUEST TO A LOCAL SERVER (120), AND WHEN THE HTTP REQUESTS ARE THEREBY REDIRECTED, THE HTTP SERVER (120) PRESENTS THE TERMINAL DEVICE WITH INFORMATION SPECIFICALLY RELATED TO THE BROWSER BASED AUTHENTICATION.

摘要： A method is described for receiving a multicast in user devices in a network issuing a request to join a multicast group, identifying multicast data packets associated with the multicast group, monitoring transmissions of the multicast data packets to determine whether the identified multicast data packets are being transmitted in an already established unicast session and establishing a unicast session and processing multicast data packets if an already established unicast session does not exist A method is described for receiving a multicast transmission in user devices in a network establishing a unicast session with a dedicated terminal, identifying multicast data packets associated with a multicast group, monitoring transmissions of the multicast data packets and processing the multicast data packets by the dedicated terminal. Additonally, an apparatus is described for accepting a request to join a multicast group, for identifying multicast data packets associated with the multicast group, establishing a unicast session, for encapsulating said multicast data packets in a unicast frame and for forwarding the unicast frame via the unicast session.
