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： 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 that typically prepares an MPEG-2 for retransmission at the local level. When a transcoder, capable of de-multiplexing and MPEG-2 transport stream receives a program it de-multiplexes the stream based on PIDs assigned to each transport packet. This de-multiplexing function extracts several components from a transport stream: video and audio PES/ES associated with programs and PSI (PAT and PMTs).

摘要： A General Packet Radio Service (GPRS) network (141) includes at least one, and preferably, a plurality of radio access networks (161–16m), each providing radio access to one or more mobile terminal users (121–12n). Associated with one or more of the access networks is a corresponding one of a plurality of Serving GPRS Service Nodes (SGSNs) (241–24m), each node serving to identify and authenticate a mobile terminal user. Advantageously, each SGSN also serves to cache IP packets from a sending mobile terminal user and to examine each packet to determine if the destination IP address corresponds to another mobile terminal user in the network. If so, then that SGSN routes the packet to the destination mobile terminal user. Otherwise, if the packet destination lies outside the network, the SGSN routes the packet to a gateway (32) for routing beyond the network.

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 wireless Local Area Network provides data service through a data LAN and also provides video broadcast service through a video LAN. A wireless LAN subscriber accesses the video LAN through one of a plurality of Video Access Points (VAPs) 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 public wireless LAN permits receipt of non-authentication traffic, such as access information requests, from a mobile wireless communications device prior to device authentication by partially opening a controlled port within an access point. The wireless LAN re-directs such non-authentication traffic received at the AP from the mobile wireless communications to a local web server. 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 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 method of 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： The Quality of Service (QoS) level/service level within a wired network associated with a wireless Local Area Network (LAN) is controlled by assigning to each incoming information frame a Virtual Local Area Network (VLAN) number in accordance with the QoS level/service level determined for that frame. The frame is then routed in the network in accordance with the VLAN number to assure that the path(s) carrying the frame have the requisite characteristics, such as bandwidth, to satisfy the determined QoS level/service level.
