摘要： An access arrangement (11) provides secure access by at least one mobile communications device (121-123) 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： 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 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： A method for downloading and displaying a video program using a mobile terminal in an interworking environment that includes a first radio access network having a first data transfer rate and a second radio access network having a second data transfer rate faster than the first data transfer rate. The video program is downloaded through the first or second networks at the first or second transfer rate, respectively. The downloaded video program is displayed at a predetermined playback rate. Excess portions of the downloaded video program that result when a rate at which the video program is downloaded exceeds the predetermined playback rate are buffered. A third data transfer rate that is lower than the first transfer rate is calculated in response to the predetermined playback rate, the buffered excess portions and the time duration of the remainder of the video program. The third data transfer rate is negotiated with the first network for downloading the video program when the difference between first and third data transfer rates exceeds a threshold level.

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.
