Abstract: 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).

Abstract: A method for communicating between a cellular system and a client terminal such as a mobile terminal by way of a standard wireless LAN and the Internet allows data communications to traverse the core of the cellular network, thereby allowing monitoring of the time and volume usage by the subscriber for billing purposes. The mobile terminal has a communication protocol for communicating with the wireless LAN, over which is a EAP/EAPOL protocol. A Radio Adaptation Layer (RAL) protocol overlies the EAP/EAPOL protocol. At the cellular system, a Serving GPRS Support Node establishes initial control contact with the mobile terminal by way of EAP/EAPOL. During authentication, the Support Node gives the mobile terminal parameters for an alternative tunnel connection. Once authorization is complete, the mobile terminal closes the EAP/EAPOL connection and opens a new connection tunnel to the Support Node using the parameters.

Abstract: 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.

Abstract: 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)).

Abstract: 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.

Abstract: A method for performing a handover (300) of a mobile terminal (330) between a 3G cell (302) and a WLAN cell (320) when the mobile terminal (330) moves within a 3G cell (302) into the coverage area of the WLAN cell (320) . The present invention proposes that the handover be performed when there are no active calls (324) . If there are ongoing calls, method proposes to wait until the calls are terminated before the handover is performed. After the ongoing calls are terminated, the handover is performed by disassociating (324) from the radio access network of the 3G cell (302) and associating with the access point of the WLAN (320), using the relatively straightforward disassociation and association procedures. The handover method according to the present invention obviates the need for complex and expensive protocols to ensure a seamless and error free handover of calls when moving from the coverage of the 3G cell (302) to the coverage of the WLAN cell (320) . This method can be used with either the loose coupling arrangement or the tight coupling arrangement.

Abstract: An apparatus and a method for implementing a paging mechanism in a wireless LAN, for example, a wireless LAN according to the Hiperlan 2 Technical Specification, for allowing a base station, or an access point, to page a mobile terminal that is not connected with, or associated with, the access point. The present paging mechanism is implemented by transmitting a broadcast channel message (400) that includes an indication that a paging message (410) is included in the current data frame, a second broadcast channel message that includes the information specific to the paging message, and a third broadcast channel message that include information regarding the location of the second broadcast channel message in the data frame. In response to the broadcast channel message indicating the presence of the paging request, the mobile terminal acquires the second and third broadcast channel messages and determines whether the paging request is intended for the mobile terminal.

Abstract: A communications system (10) includes a wireless telephony network (12) and a wireless Local Area Network (LAN) (14), both accessible by a mobile communications device (16). To facilitate transitioning of the mobile communications device to the wireless LAN from the wireless telephony network, the wireless LAN includes a beacon transmitter (30), which generates a synchronization channel having a pattern unique to the wireless LAN. The Wireless LAN synchronization channel is received at a first receiver in the mobile communications device together with a synchronization channel from the wireless telephony. The wireless LAN synchronization channel enables the mobile communication device to synchronize with, for transitioning to, the wireless LAN.

Abstract: A wireless local area network (WLAN) (12) adheres to ANSI/IEEE 802.11 standards and communicates with user terminals (UTs) (14) in a coverage region. The WLAN (12) communicates video and audio to the mobile terminals over a downlink (16) channel. In order to maximize quality of service, the system provides for a method of inhibiting the mobiles terminals from attempting to gain control of the downlink (16) channel during transmission of program information. In particular, the WLAN (12) access point transmits data frames that are separated an inter-frame time period that is shorter than a first inter-frame period defined by the communications standard for allowing a device to gain control of the transmission channel.
