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： 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.

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： To effect seamless transition of a mobile terminal user (16) from a first radio access network (12) to second radio access network (14), a temporary home agent (19) in the second radio access network assigns the user a co-location address which becomes the source address for all packets originated by the user while accessing the second network. Packets sent in reply to those originated with the co-location address as the source address pass directly to the mobile terminal user at the second network without first being tunneled through the first radio access network. Upon the transition of the mobile terminal user to the second radio access network, the first radio access network will forward any packets addressed to the user at the first source address.

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 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.
