    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 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: 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 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 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).

    摘要: A communications network (10) advantageously provides wireless telephony service to a mobile terminal user (16) from one of a first radio access mechanism (18, 20) of a wireless telephony network (12) and a second radio access mechanism (30, 32) of a wireless Local Area Network (14). The first radio access mechanism provides service at a first quality of service (QoS) level specified in a primary Packet Data Protocol (PDP) context established with the mobile terminal user during which the mobile terminal user is assigned an address for data communication. When the mobile terminal user transitions from the first access node to the second access node, the user receives service in accordance with a secondary PDP context activated by the mobile terminal user. The secondary PDP context specifies the same data address as the primary PDP context but a different QoS level.

    摘要: A mobile terminal user (16) can trigger a handoff from a first radio access node (18) to a second radio access node (30) in a communications network by making such a request to one of the two nodes. The request made by the mobile terminal user (16) will trigger in the network (10) a command to relocate (handoff) the mobile terminal user. In response to the command, the mobile terminal user is assigned to the second radio access node (30) and is released from the first radio access node (18).
