摘要： A wireless Local Area Network (10) provides data service through a data LAN (14) and also provides video broadcast service through a video LAN (26). A wireless LAN subscriber accesses the video LAN through one of a plurality of Video Access Points (VAPs) (281 and 282) that broadcast multiple video programs on a channel having a frequency different than the frequency over which the subscriber accesses the data LAN. Each VAP maintains the video channel in a one-way broadcast-only mode to prevent a wireless LAN subscriber from seeking to uplink information on that channel. In this way, the wireless LAN can employ a common protocol for both data and video transmission, and deliver the video streams at the maximum permissible downlink transmission rate.

摘要： A mobile wireless terminal (16), upon transitioning from a wireless telephony network (12) to a wireless Local Area Network (LAN) (14), 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 (24) in the wireless telephony network identifies a Serving General Packet Radio Service Serving Node (SGSN) (18) 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： A public wireless LAN (11) permits receipt of non-authentication traffic, such as access information requests, from a mobile wireless communications device (121) prior to device authentication by partially opening a controlled port within an access point (181). The wireless LAN re-directs such non-authentication traffic received at the AP from the mobile wireless communications to a local web server (21). The local web server provides reply to the mobile wireless communications device, enabling a determination by the device whether or not to request access. The device seeks access by way of an access request received at the AP. In response, the AP re-directs the access request through an uncontrolled port in the AP to an access server (26) that authenticates device. Upon successful device authentication, the AP fully opens its controlled port to permit the exchange of traffic through that port with the mobile wireless communications device.

摘要： A user (12 1 , 12 2 ) can access a Local Area Network (LAN) (20) on a fee basis without risking transmission of an un-encrypted PIN at upon initial access. The user initially sends a request to the LAN identifying a Billing Agent (26) that maintains an account associated with the user for payment of LAN access charges. The account can be a pre-paid account identified only by a PIN known to the user. After the user has identified the Billing Agent, the LAN queries the Billing Agent for its digital certificate, which the LAN forwards to the user. The user utilizes the certificate to encrypt a PIN for transmission via the LAN to the Billing Agent for authentication. Upon successful authentication, the Billing Agent authorizes the LAN to grant access to the user, allowing the user to connect via the LAN to a private network (14) or a public network (16).
摘要翻译：用户（121,122）可以以费用方式访问局域网（LAN）（20），而不会在初次访问时传输未加密的PIN的风险。用户最初向LAN识别出一个账单代理（26）的请求，该计费代理（26）维护与该用户相关联的帐户以支付LAN访问费用。该帐户可以是仅由用户熟知的PIN识别的预付费帐户。在用户识别出计费代理之后，LAN会向计费代理查询其数字证书，LAN将转发给用户。用户利用证书加密PIN，以便经由LAN传送到计费代理进行认证。在成功认证后，计费代理授权LAN授予对用户的访问权，允许用户经由LAN连接到专用网络（14）或公共网络（16）。

摘要： An operator of a network (20) dynamically establishes a business relationship with a Billing Agent (26) to enable the network operator to receive reimbursement for access charges incurred by one or more users (121, 122 and 123). To establish such a relationship, the network operator first opens a communications channel to the Billing Agent after which the network operator and Billing Agent verify each other. Following verification, the network operator communicates proposed business terms and conditions, including access charges, to the Billing Agent. In response, the Billing Agent sends to the network operator an acceptance of business terms acceptable to the Billing Agent. After reaching agreement on the terms and conditions, the Billing Agent and network operator will each digitally acknowledge a formal agreement that embodies the agreed upon terms.

摘要： A method for mapping from an MPEG-2 transport stream to an IP-based RTP/UDP/IP stack for broadcasting service in a WLAN. All the mapping functions may be performed in a receiver transcoder (Fig. 2). Mobile devices such as laptop computers, cell phones and PDAs have limited battery power, CPU processing and memory resources. To reduce CPU processing power and consumption battery power in these devices certain data processing functions are achieved in the communicating systems, such as the de-multiplexer function (240) that typically prepares an MPEG-2 for retransmission at the local level. When a transcoder, capable of de-multiplexing an MPEG-2 transport stream (105) receives a program it de-multiplexes the stream based on PIDs (204) assigned to each transport packet. This de-multiplexing function extracts several components from a transport stream: video and audio PES/ES (112, 212) associated with programs and PSI (203) (PAT (204, 251) and PMTs (206, 258)).

摘要： Secure access by a mobile wireless terminal (14) of a wireless telephony network (10) is achieved by having a Home Location Register (30) 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) (201 and 202). 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.
摘要翻译：无线电话网络（10）的移动无线终端（14）的安全访问是通过使归属位置寄存器（30）存储终端的临时和永久身份来实现的。在初始注册后接入网络时，终端向服务GPRS支持节点（SGSN）发送临时标识（201和202）。如果网络中没有服务节点知道该终端，则终端不需要如先前所要求的那样清楚地发送它的永久标识。相反，服务节点只需要查询HLR，因为HLR可以将终端的临时身份映射到其永久身份。以这种方式，移动无线终端的永久身份保持安全。

摘要： A method for Authentication Authorization and Accounting (AAA) in an interworking between first and second networks that do not belong in the same administrative domain, using certificate based transactions. In the method according to the invention, the second network sends a public key to the first network, and a certificate to a mobile device. The certificate includes information regarding the subscription level of the mobile device and is signed with a private key of the second network. Upon detection of the first network the mobile device transmits the certificate and the first network authenticates the certificate using the public and private keys of the second network, and authorizes access to the network in response. The first network then sends a session key encrypted with a public key of the mobile device. The mobile device decrypts the session key with a private key and access the first network using the session key. In this manner, interworking is implemented without requiring the deployment of a special interworking function to bridge between the two different types of networks.

摘要： A method for Authentication Authorization and Accounting (AAA) in an interworking between first and second networks that do not belong in the same administrative domain, using certificate based transactions. In the method according to the invention, the second network sends a public key (310) to the first network, and a certificate (315) to a mobile device. The certificate includes information regarding the subscription level of the mobile device and is signed with a private key of the second network. Upon detection of the first network the mobile device transmits the certificate and the first network authenticates (325, 330) the certificate (315) using the public and private keys of the second network, and authorizes access to the network in response. The first network then sends a session key (340) encrypted with a public key of the mobile device. The mobile device decrypts (345) the session key with a private key and access (350) the first network using the session key. In this manner, interworking is implemented without requiring the deployment of a special interworking function to bridge between the two different types of networks.
