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： 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 (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 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
摘要翻译：通用分组无线服务（GPRS）网络（141）包括至少一个，优选地，多个无线电接入网络（161-16m），每个无线电接入网络提供对一个或多个移动终端用户（121-12n）的无线电接入。与一个或多个接入网络相关联的是多个服务GPRS服务节点（SGSN）（241-24m）中的相应的一个，每个节点用于标识和认证移动终端用户。有利地，每个SGSN还用于缓存来自发送移动终端用户的IP分组，并且检查每个分组以确定目的地IP地址是否对应于网络中的另一个移动终端用户。如果是，则SGSN将该分组路由到目的移动终端用户。否则，如果分组目的地位于网络外部，则SGSN将分组路由到网关（32），用于路由超出网络

摘要： The Quality of Service (QoS) level/service level within a wired network (160) associated with a wireless Local Area Network (LAN) (100, 100') is controlled by assigning to each incoming information frame a Virtual Local Area Network (VLAN) (160) number in accordance with the QoS level/service determined for that frame. The frame is then routed in the network in accordance with the VLAN (160) 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 method for controlling bandwidth allocation of first and second data packet types (e.g. TCP traffic, real time traffic, VOIP traffic) in a single rate network by determining, by a device, a throughput rate of the first data packet type (e.g. TCP traffic, non-real time traffic,…) in the network and reducing, by the device, the throughput rate of the first data packet type when the throughput rate reaches a predetermined level is described. A method for controlling bandwidth allocation of each of a plurality of data packet categories in a multi-rate network by determining, by a device, a throughput rate of one of a plurality of data packet categories/classes (the jth data packet category) and reducing the throughput rate of the jth data packet category when the throughput rate reaches a predetermined level, wherein a maximum bit rate of a data packet category is based on a distance between members of the data packet category and the device and wherein said jth data packet category transmits TCP packets, is described. In a particular embodiment, transmission control of the rate is carried out depending on the distance from the device user to the device (e.g. an Access point of a WLAN).
