Abstract: In a compressed mode, a spread spectrum communication device interleaves bit units across multiple frames using an interleaver, reduces the spreading factor using a framing/spreading unit, outputs the compressed mode frames at a predetermined compressed mode frame timing, and increases the average transmission power in the compressed mode at a radio frequency transmitter. Furthermore, a handover between different frequencies is carried out by establishing synchronization to another frequency carrier, based on a first search code and a second search code which have been detected, and moreover, a handover between different communication systems is carried out by establishing synchronization to a GSM, based on an FCCH and a SCH which have been detected.

Abstract: Systems and methods disclosed herein substantially concurrently transfer a plurality of streams of commands, addresses, and/or data across a corresponding plurality of serialized communication link interfaces (SCLIs) between one or more originating devices or destination devices such as a processor and a switch. At the switch, one or more commands, addresses, or data corresponding to each stream can be transferred to a corresponding destination memory vault controller (MVC) associated with a corresponding memory vault. The destination MVC can perform write operations, read operations, and/or memory vault housekeeping operations independently from concurrent operations associated with other MVCs coupled to a corresponding plurality of memory vaults.

Abstract: Methods, systems, and computer-readable media for collecting data from CPE devices located on a remote LAN are provided. Communication is established over a WAN with a gateway attached to the LAN. The gateway is then used to enumerate the CPE devices on the LAN. A firewall pinhole is created in the gateway for each CPE device on the LAN, and communication is established through the pinholes to the CPE devices to collect the desired data.

Abstract: In a case where internal links connected to plural mobile routers in a mobile network respectively have unique network identifiers initially set, the mobile router, when receiving a network identifier different from the initial setting advertised from another mobile router, selects either one of the network identifier initially set to the self and that advertised, as a network identifier of the internal link connected to the self. Then, if the one selected is identical to that initially set, the mobile router advertises the network identifier to within the mobile network and registers it in a home agent. If not identical, the mobile router registers the one advertised in the home agent as a network identifier of the internal link connected to the self.

Abstract: A wireless device is configured to automatically resign from an ad hoc network. In some aspects the resignation may be based on automatic detection of inactivity associated with the ad hoc network. For example, resignation from the ad hoc network may be based on absence of uplink and downlink traffic at a wireless device, absence of open sockets at a wireless device, or a lack of beacon transmissions by other wireless devices. In the latter case, a lack of beacon transmissions by other wireless devices in the ad hoc network may be indicated by the transmission of a relatively large number of beacons in succession by a wireless device.

Abstract: A method of controlling connection between nodes in a digital interface whereby a first node that is a master node determines a second node to be the master and controls a point-to-point connection or a broadcast connection to another node. The first node having the display device determines the second node to be the master in accordance with a user selection, and transmits a connection command of a predetermined format for transmitting a data stream to the second node. The second node determined as the master in accordance with the transmitted connection command of the predetermined format is allocated with a channel and a bandwidth from an isochronous resource manager (IRM), and performs a point-to-point connection between the second node and the first node to transit the data stream. Thus, the transmission/reception, reproduction, and control of the data stream of the program can be smoothly performed.

Abstract: Within a wireless network, feedback information is used to determine channel quality. A node in the network receives a configuration message indicating at least a first type of feedback information and a subset S1, wherein S1 is a subset of S0, and wherein the set S0 comprises all possible values of the first type of feedback information. The node selects an element E1 from the set S1 and transmits the selected element E1 in a feedback transmission instance.

Abstract: A control system controls a physical layer quality of user data transmitted between first and second ends of a serial bus. The control system comprises a first line driver that has a control input that controls the physical layer quality at the first end. A physical layer quality sensor senses the physical layer quality at the second end and generates control primitives that are fed back over the serial bus to the control input to provide closed loop control of the physical layer quality.

Abstract: Methods of allocating a plurality of periodically distributed frames of communication between a first wireless transceiver and a second wireless transceiver are disclosed. One method includes detecting periodic data for transmission between the wireless base station and the wireless mobile unit. A transmission map that maps frequency and time slots is generated for transmission of the data packets. Allocation information is included within less than all of a plurality of transmission maps of the plurality of periodically distributed frames. The allocation information designates frequency and time slots in which data packets identified as a periodic data type are transmitted to the second wireless transceiver for the plurality of periodically distributed frames.

Abstract: A telecommunication system and method for communicating between at least two end users over a telecommunication network, where the communication is defined by a set of parameters. At least two entities, such as one or both of the end users and/or the service providers negotiate an agreed set of values for said parameters that define the desired communication. The entities also negotiate a warranty agreement with the network service provider defining at least one of the agreed parameters to be warranted including a compensation method to be applied should said at least one monitored parameter fail to meet the corresponding one of said agreed values. The agreed warranted parameters are monitored once the communication is established and, in the event of a failure of the monitored parameters to meet agreed values, at least one of the entities is compensated in accordance with the agreed compensation method.

Abstract: A method (18) for scheduling packet data transmissions in a wireless communication system wherein a per-user Priority Function (PF) (24) is based on a channel condition indicated by a Rate Request Indicator (RRI). The method also considers fairness criteria dictated by predetermined Quality of Service (QOS) requirements. In one embodiment, the rate request indicator is a Data Rate Request (DRR). In another embodiment, the rate request indicator is Carrier-to-Interference (C/I) information. In the exemplary embodiment, the base station calculates a Priority Function (PF) for the multiple mobile users. Each PF is a function of the rate request indicator and the projected throughput of a given mobile user. The PF values allow the base station to schedule active mobile units having pending data. The scheduling produces an approximately equal share of the allocated transmission time to the multiple mobile stations.

Abstract: Automated methods and systems for determining and setting router QoS adjustments to control the service level of VoIP voice communications in a packet switching network supporting both voice and data communications. Network topology and service level requirements are processed to determine QoS settings for each of the routers. The QoS settings are transmitted to the routers, for example in the form of a router configuration file, to set the QoS adjustments to achieve the desired VoIP service level. The invention is applicable to packet switching networks comprising routers or equivalent electronic switches providing electronically adjustable QoS settings.

Abstract: A system and a method connect mobile devices via channels which connect a first terminal and a second terminal. A bearer establishment of the connection is identified by the first terminal and/or the second terminal. The first terminal accesses information to identify the second terminal and/or to select a first codec for data to transmit the data in the first codec between the terminals. The first terminal alternatively chooses a first codec without accessing the information. The data in the first codec is transmitted from the first terminal to the second terminal without an exchange of codec capabilities and/or codec preferences. The second terminal is capable of receiving the data sent in the first codec. Alternatively, the second terminal may be incapable of receiving the data sent in the first codec. The first terminal uses capability and/or preference information received from the second terminal to detect cases whether the second terminal is incapable of receiving the data in the first codec.

Abstract: In a telecommunications system, in which a connection comprises a part with an interworking function at both ends, a channel is allocated to the connection between the interworking functions. The required channel capabilities may vary during the connection, whereby the channel capabilities should be changed. When the first interworking function detects that a channel capability must be changed, a first message, which indicates the desired capability change, is transmitted (2-1) to the second interworking function; and the channel capability is changed (2-3,2-5) into the desired one at both ends of the part.

Abstract: System and method for receiving transmissions in a wireless communications system. A preferred embodiment comprises a receiver (such as receiver 400) that can despread and then demodulate a symbol from a transmitter that first spread and then modulated the symbol. By reversing the processing order, the demodulation can be performed at a lower data rate and therefore reducing computational and power requirements.

Abstract: A first switch flashes an FDB upon receiving an FDB flash frame and then floods a multicast group join query message (QRY1). A terminal sends a group join message (RP1) back to the first switch. A second switch, a third switch and the first switch receive RP1 and perform IGMP/MLD snooping, respectively.

Abstract: The invention provides a method and system for distributing personalized content to potentially large numbers of recipients. A pool is selected, from among all content available for distribution, of those content elements that will be made available for simultaneous distribution, and personalized content is selected for distribution from that pool. The content of the pool can change with new selections over time. For each individual recipient, content elements in the pool are examined to determine if they are predicted to be of sufficient interest to that recipient for distribution, and if so, those content elements are distributed. If not, successive content elements in the pool are examined, relaxing the standard for sufficient interest, until at least one content element is found and distributed to the individual recipient.

Abstract: A unified architecture for a multipoint VC session and interactive broadcasting system is provided that includes a server, one or more video accessing points, reflectors and client machines. The server sets up the video communication sessions (VC sessions), each of which is hosted by one video accessing point. The server downloads the A/V client software to client machines. Reflectors direct audio/visual signals to client machines. The reflectors are coupled to the video accessing point and receive a control signal from the video accessing point in order to direct the A/V signals from the client machines participating in the VC session. The client machines process all of the A/V signals. This system for distributing the VC session tasks across these components reduces any bottleneck effect from using a single, central control point to direct the VC session and route the A/V signals.
