Abstract: Systems and methodologies are described that facilitate identifying peers based upon encoded signals during peer discovery in a peer to peer network. For example, direct signaling that partitions a time-frequency resource into a number of segments can be utilized to communicate an identifier within a peer discovery interval; thus, a particular segment selected for transmission can signal a portion of the identifier, while a remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource can be reserved (e.g., unused) to enable identifying and/or correcting timing offset. Further, signaling can be effectuated over a plurality of peer discovery intervals such that partial identifiers communicated during each of the peer discovery intervals can be linked (e.g., based upon overlapping bits and/or bloom filter information).

Abstract: An initiator node in a local cluster included in a wireless network receives an admission request to execute an application comprising a set of tasks. If the initiator node is unable to map the set of tasks to nodes included in the local cluster, the local cluster head node forwards the admission request to the cluster head node of successive clusters in the wireless network in order to have at least one node in each of the successive clusters send resource availability information to the initiator node. The initiator node attempts to map the set of tasks to a subset of the nodes from which resource availability information has been received. This is repeated until the initiator node is able to map the set of tasks to a subset of the nodes in the wireless network or until there are no additional clusters to forward the admission request to.

Abstract: Bandwidth utilization over bearers in a fixed cellular network is improved by reducing the amount of data required to be transported. At each side of the bearer, data blocks (such as Iub blocks) are received and, prior to transmitting them across the bearer, they are analyzed to determine if they can be modified in such a manner to decrease the amount of data. On the other end of the bearer, received blocks are analyzed to determine if they have been modified, and if so, the blocks are reconstructed to a format that may not be identical to the original format but, that is operationally equivalent from a user perspective. The modifications to the blocks can be based on the type of data being transmitted. For instance, if the data is for a video session or and audio session, the modifications can be different. Information regarding the reconstruction of the blocks can be sent to the other end of the bearer as a part of the data or through other channels.

Abstract: Interconnect of communication between mobile objects by another mobile object is enabled. Station A transmits its own identifier to another mobile station on a broadcast basis. Out of other mobile stations, Station B receives the identifier of Station A, and returns a response including its own identifier. Station A notifies Station B of identifiers of nodes with which it can communicate. Station B notifies Station A of identifiers of nodes with which it can communicate. This sequence of processing enables information on nodes with which either station can communicate to be exchanged between Stations A and B, and a communication path to nodes to be found between Station B (station A) and another node via Station A (station B).

In order to enable a second unit providing or forwarding the data packets to the node to influence the QoS for the transmission, it is proposed that the method comprises transmitting data packets of a specific data flow from the node to the first unit using a quality of service treatment which is selected based on a quality of service treatment associated with a quality of service identifier. The quality of service identifier is inserted by a second unit to each packet of the specific data flow. The invention relates equally to a terminal equipment, to a node, to a mobile communication network and to a system comprising means for realizing the proposed method.

Abstract: A system for scheduling access times for transmitting data traffic in a WLAN including both isochronous streams and asynchronous bursts characterized by widely varying parameter values generates a succession of service periods, each having adjustable length and including two or other number of primary access intervals. The service periods may also be adapted to include one or more asynchronous burst periods, each immediately following a primary access interval. Access times for each isochronous stream are scheduled only during a primary access interval, or an immediately following extension period. Asynchronous bursts are scheduled for access times only during asynchronous burst periods. Epoch lengths fluctuate dependent on the dynamic needs and priorities of user traffic. Thus, an access time scheduling is made available that can readily adapt WLAN access to continually changing data traffic conditions, and thereby provide QoS by scheduling access times accordingly.

This is made possible by converting data between formats so it can be routed at a switch. This provides a particular advantage. A cell phone can now transparently change between base stations that are owned and operated by different companies.

Abstract: A wireless media access control supports asynchronous communication and overlapping transmissions. Here, a wireless node may determine whether to request or schedule a transmission based on control messages it receives from neighboring nodes. In some implementations a scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. In some implementations a monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may otherwise have been transmitted during the scheduled transmission period. In some implementations data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

Abstract: A method automatically establishes a base station operating and maintaining channel in International Mobile Telecommunications 2000. A BS initiates a BOOTP Request to the base station controller (BSC) or RNC through the IPOA channel between the BS and the BSC/RNC, and then the BS obtains the IP address allocated to it from the reply from the BSC/RNC, so that an operating and maintaining channel is established between the BS and the BSC/RNC. A BS can establish a maintaining channel for itself automatically when starting, avoiding IP address confliction and parallel starting problems. Moreover, establishing a maintaining channel for the BS results in an easy and small workload. Thus programs and data can be loaded automatically to the BS, and the BS can be effectively configured and maintained by a remote device (i.e., the operating and maintaining station of the BS) at a low cost, and good quality is realized.

Abstract: In a wireless USB data transfers over UWB, software configures hardware thresholds to control data transfer in a manner that uses bandwidth for good connections over bad connections, given the high error rate experienced with wireless USB. Periodic transfers are first attempted before asynchronous transfers, as long as the periodic transfers are successful. When failures are occurring, the hardware includes a mechanism having a software-configurable threshold specifying the number of errors a given endpoint can tolerate before it is paused in the schedule. By pausing transfer attempts that are likely to again fail, endpoints with successful transfers are favored over those experiencing errors. When the number of active transfers pending exceeds a software-configurable notification threshold for isochronous endpoints, the hardware notifies the software of this state, corresponding to a low-buffer condition at the receiver.

Abstract: The invention relates to communications systems, and particularly to enhancing tolerance to failures in network elements and transmission systems. The fault tolerance is achieved by providing two or more active ATM permanent virtual channel (PVC) connections between a core network element and an access network element, and providing a separate ATM interface unit for each such ATM PVC connection in the core network element. The user and signalling traffic is distributed among these active connections and interface units. In case of a failure in one of the ATM PVC connections or interface units, the communication is maintained over the other connection(s) and interface unit(s). Thus, only part of the transport capacity is lost, and a total block of communication is avoided. Any new communication will be setup over the other connections.

Abstract: Asynchronous Transfer Mode (ATM) data is transmitted in Available Bit Rate (ABR) service over a network path including a spacecraft. The spacecraft payload switches do not provide an indication of congestion, so conventional ABR feedback control using Resource Management cells is ineffective. In one avatar of the invention, the Network Control Center coacting with the spacecraft produces signals representative of congestion in services other than ATM ABR service, and these congestion signals are coupled to the terrestrial source terminal, where return or back Resource Management cells are modified with data derived from the congestion signals, to close a feedback loop including the source of ATM ABR signals, the source terminal, and the spacecraft. The feedback loop tends to maintain excess bandwidth in use for ABR purposes, and tends to prevent congestion.

Abstract: In a W-CDMA communication system, even the RNC goes into the congestion state due to increasing user data, the RNC may distribute loads while continuously performing its processing without causing system down. An ATM network used in a RAN is IP-networked, where a C plane processing device for signaling processing and a U plane processing device for user data processing are provided in a physically separated manner. With the U plane processing device, a backup system is prepared independently from an active system. When congestion occurs in the active system, part of processing is switched to and inherited by the backup system.

Abstract: The present invention proposes a method for controlling transmission resources of a radio access network adapted to transmit data packets in real time traffic and in non-real traffic, the method comprising the steps of obtaining information related to transmission resources required for handling real time traffic; and reserving transmission resources for handling non-real time traffic based on a knowledge of the overall available transmission resources of a radio transceiver device of said radio access network and the information related to the transmission resources required for handling real time traffic by said radio transceiver. Transmission resources are subsequently activated based on channel elements which are identified by pre-selected channel element identifiers. This alleviates the use of hitherto required time consuming channel activation procedures as well as the need to refer to any bearer information.

Abstract: A method for performing discontinuous transmission in an asynchronous transfer mode is described, wherein a downlink transmission of an ATM cell is performed each time a predetermined number of signal frames indicating a speechless period has been supplied, and wherein an uplink transmission of an ATM cell is only performed when a signal frame indicating a useful information has been supplied. In the downlink transmission, an idle frame can be generated at the receiving end, when no ATM cell is received. In the uplink transmission, a signal frame indicating a useless information can be generated, when no ATM cell is received. Thereby, only those signal frames required at the receiving end are transmitted. Moreover, known transmission functions and elements of a synchronous transmission system can be used at the respective ends of transmission.

A master station has a scheduler for determining a transmission band assignment including information about the transmission timing of the data, a transmission amount, and a station that is allowed to access. The scheduler regularly carries out scheduling, and optimizes the transmission band to be assigned dynamically according to the communication type of the data and a state of data transmission. The master station gives a transmission band assignment which is determined by the scheduler to each slave station. A transmitting station executes data transmission (access) to a receiving station based on the given transmission band assignment.

Abstract: A packet transmission method and apparatus for transmitting data packets via a telecommunication network are described, wherein the quality of a received data packet is judged and the data packet is tagged in response to the result of the quality judgment. The tagging is performed by adding a dropping information, wherein a tagged cell is dropped on the basis of the dropping information and a predetermined dropping condition such as a transmission congestion situation and/or an overuse of a contract of a particular connection. In the uplink direction, the quality judgment can be based on an error check or a comparison of a quality base likelihood parameter with a threshold value. In the downlink direction, the quality judgment can be performed on the basis of an uplink quality parameter and/or a downlink power control status. Accordingly, in case of a congestion and/or an overuse of a particular connection, low quality transmission packets are dropped first to thereby reduce traffic.

Abstract: A wireless telecommunications system comprises a radio network layer for carrying mobile-specific signaling, and a transport layer for establishing user channels between system nodes over a transport network. The transport network is visible to the radio network layer only via a primitive interface through which it can request transport services. The invisibility of the transport network to the radio network layer makes the radio network layer independent of the underlying transport network and enables the use of different transport network technologies. The radio network layer signaling procedures and connections are mapped with the underlying transport layer signaling procedures and connections by using binding information at one end of the connection leg, which is exchanged between the network and transport layers through a primitive interface, and used to “identify” the radio network layer and the transport layer connection setup signaling carried out between the nodes.

Abstract: A method of establishing a supplemental channel (SCH) to provide burst timing for high-speed data transmission in a mobile communication system is disclosed. In the SCH establishing method, a source base station transceiver determines that a traffic burst exists and sends a target base station transceiver a burst request message. The burst request message includes forward and reverse burst timing information and channel use time information, which is determined in consideration of a discontinuous transmission (DTX) mode, in order to reserve necessary resources, when a large amount of high rate data is to be transmitted. Then, the target base station transceiver sends the source base station transceiver a burst response message including information about resources committed to the traffic burst.
