Abstract: A dynamic mobile service control architecture for policy-based control and charging of a mobile data network is described. Reference point links logically connecting a subscription profile repository and a service gateway allows the service gateway to receive information about a subscription to a service by a subscriber and forward this subscription information to an external application function that is providing the service to the subscriber through the mobile data network. Reference point links logically connecting a policy server with the service gateway allows the service gateway to receive and enforce policy rules on service data flows passing through the service gateway.

Abstract: A radio base station transmits user common data provided from a user common data control apparatus connected to a communication network to a plurality of mobile stations by radio. The radio base station includes a frame loss detection unit configured to detect loss of user common data that occurs on a transmission route between the radio base station and the user common data control apparatus, and a timing adjustment unit configured to change transmission timing of the user common data for the mobile station according to the loss of the user common data.

Abstract: A communication node contains intelligence for directing both internet protocol (IP) packets and Asynchronous Transfer Mode (ATM) cells toward their destinations. The ATM cells and IP packets may be received within a common data stream. The respective devices process the ATM cells and IP packets to direct the cells and packets to the proper output ports towards their destinations. The device is capable of performing policing and quality of service (QOS) processing on both the ATM cells and the IP packets.

Abstract: In general, techniques are described in which a plurality of network switches automatically configure themselves to operate as a single virtual network switch. A virtual switch is a collection of individual switch devices that operate like as single network switch. As described herein, network switches in a network that are capable of participating in a virtual switch may automatically discover one another. The participating network switches may then elect one of the participating switches as a master switch. The master switch may generate forwarding information and store the forwarding information in the participating switches, including the master switch. The forwarding information causes the participating switches to act like a single network switch.

Abstract: A method selects antennas in an OFDMA wireless network including a base station and a mobile station. The mobile station measures a channel state of a downlink in a downlink subframe using different subsets of available antennas, and selects a subset of receive antennas for downlink reception based on the channel states between the base station and the different subsets of antennas at the mobile station. The base station measures the channel state in an uplink using an uplink subframe received in the base station from the mobile station, and selects a subset of transmit antennas for mobile station's uplink transmission based on the channel states between the base station and different subset of antennas at the mobile station.

Abstract: A mobile ad hoc network (MANET) may include a plurality of mobile nodes. Each mobile node may include a wireless transceiver and a controller cooperating therewith for exchanging isosynchronous Internet Protocol (IP) communications with at least one adjacent mobile node. The isosynchronous IP communications may comprise at least one of voice communications and data communications.

Abstract: An interface for a networking device. A network interface module existing within a networking device monitors certain contacts of a network connection to identify a protocol of the networking system to which it is connected. Based on the detected protocol, the network interface module selects a set of configuration information with which to configure the networking device.

Abstract: The present invention is a novel and improved method and apparatus for supervising a potentially gated channel in a wireless communication system. The first method is an extension of the method used in IS-95 with empty frames simply ignored, but with potentially different thresholds. The mobile station maintains a counter of consecutive bad frames, COUNT1, and a counter of consecutive good frames, COUNT2. COUNT1 and COUNT2 are set to zero at the beginning of a call. For each frame received, the mobile station determines if it is a good frame, a bad frame, or an empty frame. If the received frame is a good frame, COUNT1 is reset to zero and COUNT2 is incremented by 1. If the received frame is a bad frame, COUNT1 is incremented by one and COUNT2 is reset to zero. If the received frame is an empty frame, COUNT1 and COUNT2 are unchanged. If COUNT1 reaches a threshold value, TH1, the mobile station shall disable its transmitter.

Abstract: A system and method for automatically generating a protection route as an alternative to a working route through a network of switches prior to network failure. A switch selects the proposed protection route so that the protection route is disjoint from the working route. Next, a switch or switches determines whether bandwidth is available for the proposed protection route. If so, the protection route is set-up for activation when needed.

Abstract: The present invention provides a highly accurate synchronization method for a satellite communication system (100). The system maintains a downlink symbol counter at an earth terminal and determines a downlink symbol count representative of the time of arrival of a burst transmitted from the earth terminal to a satellite (106, 206). The earth terminal adjusts the downlink symbol counter to correspond to the downlink symbol count (136, 220) upon arrival of a predetermined reference point in a downlink frame. A timing error may initially be determined by launching an entry order wire from the earth terminal to the satellite (116). The timing error may be transmitted to the earth terminal using a correction code which indicates the transmission is early, late, absent, or no change is required (134, 218). The terminal may make additional periodic timing adjustments based on the length of the propagation path between the earth terminal and the satellite (108, 208).

Abstract: The invention relates to a method at a cellular radio communications system which makes possible that the probability of congestion for multislot mobiles in said system is reduced. In the future, the GSM-system will offer high speed data services, at which one of these is HSCSD (High Speed Circuit Switched Data). The HSCSD-service includes two services called “fixed service” and “flexible service”. At the first mentioned service, the mobile is allocated a fixed number of time slots which shall be allocated during the whole call, whereas at the last mentioned service the number of allocated time slots can vary during the course of the call. The mobile stations of today with their simplex filters can perform only one thing at a time, i.e. either transmit, measure or receive signals. It therefore is important to have possibility to allocate consecutive time slots for multislot mobiles.

Abstract: A cell flow synchronization establishing system of an ATM access system, capable of establishing synchronization of cell flow between a mobile station and base stations at the time of hand-off process, is provided. First buffer control unit is provided in the ATM switching station, and second buffer control unit is provided in the mobile station. The first buffer control unit reproduces cell stream to be transmitted by guaranteeing orderness of ATM cell between the first buffer control unit and the second buffer control unit and buffer clear processing is carried out based on predetermined synchronization establishment processing sequence before and after occurrence of handoff.

Abstract: The assignment result reception circuit 11 receives the accumulation assignment result from the external portion, and sends the already-assigned input port and output port information to the assignment request mask circuit 12. The assignment request mask circuit 12 uses the already-assigned input port and output port information received from the assignment result reception circuit 11, performs the mask process on the connection assignment request received from the external portion, and sends its result to the M×N scheduler circuit 13. The M×N scheduler circuit 13 determines the assignment of the port connection in accordance with the information received from the assignment request mask circuit 12, and sends the connection assignment result to the external portion and the assignment result transmission circuit 14.

Abstract: In a TDMA (Time Division Multiple Access) wireless communication system, mobile stations are sorted according to their PV (Protocol Version), and packed by an enhanced FRP (Frequency Re-Packing) function or an enhanced IDCS (Interference Driven Channel Selection) function so mixing of mobile stations with different PVs on the same carrier will be avoided as far as possible. This allows mobile station capabilities to be used with greater advantage, in situations where a protocol or other performance feature used on a carrier must be compatible with the least capable mobile station on the carrier. In a broader sense, the mobile stations can be sorted and then allocated based on any appropriate indicator of mobile station capability, for example PV, mobile station ESN (Electronic Serial Number), and so forth. In this way, a common capability of all mobiles on the same carrier, can be maximized for some or all carriers within a cell.

The digital loop carrier (14, 56) provides subscriber line interfaces (120, 150), network trunk interfaces (122, 152), and a cross-connect matrix (124, 154). The intelligent peripheral (12, 54) is coupled to the digital loop carrier (14, 56) for performing call processing functions. The general purpose computing platform (12, 52) is coupled to the digital loop carrier (14, 56) and intelligent peripheral (12, 54) for controlling and managing call processing operations thereof. The general purpose computing platform (12, 52) may be integrated or co-located with the intelligent peripheral (12, 54).

Abstract: A telephone network is provided with a service node SN (50) having an interface to the Internet. The SN (50) has a voice service browser (51) which it can use to access resources on the Internet, these resources preferably being held on WWW servers (52). A user of the telephone network places his own service logic programs, in the form of applets 55, on his WWW home page (53) together with content items such announcements and messages; these content items may be embedded in the applets (55) or held in separate files. When the SN (50) receives a service request to supply a service to a user identified as having his own service logic programs and content items available on the WWW, the voice service browser (51) reaches out over the WWW to retrieve the relevant service applet (55) and any associated content items. The voice service browser (51) then executes the applet (55) to provide the desired service including the delivery of content items through a text-to-voice converter or the like.

Abstract: A subscriber (12, 14, 16) initiating an Internet telephony call may receive specific content targeted to that subscriber in accordance with a match between at least one of the dialed number and the calling party number. Upon receipt of the subscriber's Internet telephony call, an Internet Telephony Service Provider server (18) searches each of a dialed number database, a calling party number database and a default database to establish a match between the calling party number, the dialed number or a range of either numbers. Upon finding a match, the Internet Telephony Service Provider server retrieves corresponding content, typically in the form of a URL that links to an associated web site, to provide to the subscriber who may elect to retrieve that information at the subscriber's discretion.

Abstract: The present invention provides a method and apparatus for establishing dedicated local area network (LAN) connectivity between network elements (NEs) in an optical transmission network without using any of the payload transport capacity available. In order to provision dedicated LAN connections between NEs, the invention reallocates existing overhead functionality to provide dedicated bandwidth for LAN communications between NEs. At each NE, a respective LAN interface unit provides access to this dedicated bandwidth and allows LAN devices such as personal computers (PCs), servers and monitoring equipment to communicate across NEs of an optical transmission network without consuming any payload transport capacity available therein.

Abstract: The present invention enables a traditional analog telephone to be used with VoIP applications. For example, the user could connect their standard 900 MHz telephone to this invention, establish a VoIP call and enjoy the freedom of movement their cordless telephone provides. The preferred embodiment of the present invention minimizes overhead to the host computer via a dual CODEC modem that incorporates a DSP capable of simultaneous communication with the two CODEC modules. This architecture facilitates a latency and communication overhead reduction as the analog voice signals effectively “stream” from the first CODEC to the second CODEC.

Abstract: An integrated circuit comprising a plurality of functional modules and interconnected via a packet router for conveying request and response packets is described. Transactions involve the dispatch of request packets and receipt of corresponding response packets. Each packet conveys a number of transaction attributes which can control how the packet is managed by control circuitry which controls the flow of packets on the packet router. For example the transaction attributes can include a transaction number, a grouping indicator, a priority indicator and a post indicator.

Abstract: Engine control apparatus for use in passenger cars and other applications includes a special calibration of the intake mixture preparation system. Although this calibration duplicates the optimum calibration for use with a continuously variable transmission (CVT), the apparatus instead includes, for reasons of practicality, a discrete-ratio powershift transmission. Also included is a feedback control system which dispenses with the conventional mechanical connection between accelerator pedal and engine throttle valve. This drive-by-wire control system operates the engine as closely as is practical to the optimum CVT engine operating schedule, a predominantly wide-open-throttle engine operating schedule. The overall combination of special engine calibration and drive-by-wire control with a discrete-ratio transmission can offer the majority of the fuel economy advantage available with a CVT.
