Abstract: An apparatus and method changes an assignment of a receiver channel element (302a-302n), such as a RAKE receiver finger based on transmit power control information (212), such as a power control bit or other suitable information, that is used as part of a closed loop transmit power control system between a transmitter and receiver. In one embodiment, a transmit power control information generator (204) produces the transmit power control information (212) on a per channel basis based on received symbol energy (210) of a received spread spectrum signal (202). A receiver channel element management module (206), analyzes the transmit power control information (212) and produces receiver channel element control information (214) to suitably change assignment of receiver channel elements, such as receiver fingers, based on the transmit power control information (212). The reassignment of fingers is rapid and provides close tracking of rapidly changing radio frequency environments.

Abstract: A method and apparatus for automatically establishing a set of calls in a network is presented. A first device determines a maximum number of simultaneous calls that can be processed by a second device. The first device then determines a time interval necessary to allow calls to be established in a set of channels associated with the second device. Using the maximum number of simultaneous calls and the time interval previously determined, the set of calls are established.

Abstract: The universal Internet based telephony system is implemented as a process that is accessible via an Internet WEB page and executes on the WEB server that hosts the WEB page and/or a back-end Internet telephony server which is accessed and controlled by the WEB server. The customer accesses the universal Internet based telephony system via any existing Java Enabled Internet Browser software resident on the customer's personal computer, either as an adjunct process thereon, or as a dedicated Internet telephony process. When a customer accesses the Internet WEB page and clicks on the universal Internet based telephony system icon, the WEB server on which the WEB page resides executes the resident universal Internet based telephony system hyperlink script and transfers a newly opened browser session to the universal Internet based telephony system WEB site.

Abstract: The protection of data against illicit transfer with respect to specific data can be ensured. An integrated receiver decoder determines whether or not ATRAC (Adaptive Transform Acoustic Coding) data requiring authentication is contained in selected piece-of-music data in accordance with determination data added into transmitted data. When ATRAC data requiring authentication is contained, the integrated receiver decoder performs an authentication process between it and a storage which is a transfer destination of the ATRAC data, and performs downloading of the ATRAC data after confirming that the storage is a valid apparatus to which the downloading may be performed.

Abstract: Tuning for connection admission control (CAC) algorithms in broadband ATM networks is accomplished using an overbooking technique based on aggregate effective bandwidth, AEBW, as an approximation to required bandwidth for given levels and classes of network traffic. An overbooking gain factor, &agr;t is developed—typically in a network operations system—based on long-term measurements supplied periodically by network switches. In operation, overbooking is introduced in small increments until a threshold (such as a cell loss threshold) is reached, at which point overbooking is reduced in a large step. A variety of network measurements can be used to apply the present invention to a range of traffic and service contexts.

Abstract: A first connection stage includes connecting by a switched network control device a call from a first terminal with a terminal selection device, noticing “there is no terminal to be connected” to the first terminal as a selected result from the terminal selection device when no terminal is selected, and disconnecting the call. A second connection stage includes connecting by the switched network control device a call from a second terminal with the terminal selection device, noticing “there is a terminal to be connected” and “a connection number of the first terminal” to the second terminal as a selected result from the terminal selection device when the first terminal is selected, and disconnecting the call.

Abstract: An improved reclocker circuit and router cell are provided that are particularly useful when configured into a router matrix comprising a plurality of interconnected router cells. The improved reclocker circuit includes an integral N-to-1 multiplexer (MUX), wherein N is at least three. The improved router cell includes the reclocker/MUX circuit, a switch, and a fan-out circuit. A plurality of ports are coupled to the router cell circuitry, including an input port, an output port, a plurality of expansion input ports, and a plurality of expansion output ports. The improved router cell couples either the input port or one the expansion input ports to its output port, and it also couples the input port to each of the expansion output ports. By using the improved router cells in the design of a router matrix, jitter induced by the reclocker circuits is minimized.

The transfer controlling unit can generate the packetized data simply by controlling the transfer of the header information stored in the header information memory and the encoded data held in the ES buffers, whereby the media multiplexing can be readily achieved.

Abstract: A method and apparatus dynamically assigns each of a plurality of different information streams associated with one wireless communication unit (12a), to independent communication resources from different communication resource pools from each of a plurality of different wireless network elements (14a-14n), based on, for example, quality of service requirement data determined for each of the information streams. As such, the wireless communication unit (12a) may establish two or more separate links using two or more completely independent radio resources from different wireless base stations in the same system.

Abstract: A method and system for supporting a real-time communication on an integrated packet-based network involve accumulating information about the communication, referred to as signature data, while the communication is being setup and/or is in progress and storing the signature data in a database that is openly accessible to any applications that are connected to the network. Once signature data regarding an active real-time communication is accumulated, portions of the signature data may be utilized to further process the active real-time communication. Providing an openly accessible communication profile that is accumulated while the communication is in progress allows applications to provide a higher level of service by tailoring actions to the profile of the specific communication.

Abstract: A packet transmission control method is achieved by borrowing a first one of a plurality of channels for a first one of a plurality of existing users in response to a packet receiving request, and by transmitting packets to a new user using the first channel.

Abstract: An architecture, system and method are provided for efficiently transferring packets of data across a communication network. The communication network is structured such that there are hierarchical levels of high speed switches existing throughout the network. Distributed routing of packets is achieved by comparing identification numbers of only select switches with the destination address on a field-by-field basis. Not all fields need be compared at all switches. Once routing is achieved within the structured network, transfer to a destination termination device occurs through a single look-up table only when departing the network if multiple termination devices are present at that exit node. The routing operation between termination devices can therefore be achieved using a single mapping operation (if more than one termination device must be selected) and is backward compatible with devices external to the network and protocols used by those devices.

Abstract: When receiving data to be transmitted from LAN 4 to WAN 5, operation information showing that operation has been executed in operation sections of a terminal connected to LAN is detected by a PC condition receiving section 111. It is judged that the operation has been executed based on the operation information during a predetermined period X before and after the time when the data are transmitted to WAN. The data received during the predetermined period X are transmitted to WAN as a result of the judging.

Abstract: A system and method permits a wireless communication terminal (such as a mobile telephone) to access Internet audio services. The wireless terminal communicates in WAP protocol to a WTA Internet server acting as a gateway between a mobile network and a wired network, and requests a channel to an audio service residing on a particular Internet origin server. The WTA server initiates establishment of an audio channel with the origin server. The WTA server also instructs the wireless terminal to answer automatically the next voice telephone call it receives, and the WTA server instructs the mobile network to place a voice phone call to the wireless terminal. The wireless terminal automatically answers, and there is then established a speech path from the wireless terminal, over the mobile network, through the WTA server, to the origin server. The wireless terminal may access the Internet audio service over this audio path.

Abstract: Active packets are utilized by a mobile terminal in a wireless network to set-up a wireless call via a signaling process, and for mobility management via a mobility process as the mobile terminal moves from one cell to another in a subnet. Active packets instantiate an agent in the fixed network to handle signaling between the mobile terminal and the fixed network, and then instruct the agent to negotiate setup of an open channel between the mobile terminal and the destination device. Moreover, active packets foster the handoff of the mobile terminal as the terminal moves from one cell to another in a subnet. Finally, the signaling process and mobility process are coordinated so that lost active packets are mitigated during roaming by the mobile terminal.

Abstract: The invention concerns an efficient strategy for sharing link bandwidth in a mixed rigid-elastic traffic environment, as well as a strategy for sharing bandwidth among elastic traffic flows. The idea according to the invention is to sharing the link bandwidth among rigid and elastic traffic by dividing the link bandwidth into a first common part CCOM for elastic as well as rigid traffic and a second part CELA dedicated for elastic traffic. Subsequently, one or more admission control parameters for the elastic traffic are determined in order to restrict the number of elastic traffic flows simultaneously present on the link. In particular, by formulating a call-level model for elastic traffic and determining a maximum number NELA of admissible elastic traffic flows based on call-level constraints for the elastic traffic related to throughput and/or blocking, the so-called throughput-to-blocking trade-off for elastic traffic can be fully considered.

Abstract: Scheduling packets are exchanged among neighboring nodes of a computer network. These scheduling packets include descriptions of a transmitting node's 2-hop neighborhood within the computer network, and nodes are able to determine transmission schedules from information received via said scheduling packets. Preferably, the computer network is a synchronized network in which time is dived into a number of frames, each of which are made up of a plurality of slots. In such cases, the exchange of scheduling packets should occur within a first number of the slots of each frame, preferably in a common communication channel. Transmission schedules may be determined, at least in part, because nodes advertise their availability using the scheduling packets. The above-mentioned descriptions may include an identification of received communication times and/or channels, an identification of requested communication times and/or channels and an identification of available communication times and/or channels.

Abstract: After receiving a time division multiplex signal including a plurality of digital data signals transmitted in accordance with different transmission schemes, the received time division multiplex signal is demodulated by a demodulation circuit, and it is judged by a detection circuit whether each of the demodulated digital data signals is received correctly or not. When it is detected that a digital data signal transmitted by any one of the plurality of different transmission schemes is not received correctly, the relevant digital data signal is replaced by a suitable signal such as a null packet signal which does not affect a correct reception of the remaining digital data signals transmitted by the remaining transmission schemes to form a corrected time division multiplexed signal even if a digital data signal is not received correctly.

Abstract: Data packets transmitted over a cable network are suppressed by hardware at the transmitting end and expanded on the receiving end. This conserves bandwidth as well as reduces the processing resource requirements in both the CM and the CMTS. An extended header element is added to a data packet that is to be transmitted over the cable network. The extended header element contains an index that is used along with the SID to access a rule. The rule is used to determine which bytes are to be suppressed at the transmitter and expanded at the receiver.

Abstract: The link layer (68, 64) of the sending end of a wireless link (66) is enhanced (10, 74) by providing a mechanism for discriminating (36, 38; 79, 82) between special, critical or otherwise important packets from among a plurality of packets send over the wireless link. Special link layer treatment (42; 89) is accorded to such special, critical or otherwise important packets, while the remaining packets are subjected to normal link layer treatment (44; 86) before transmission over the wireless link.
