Abstract: A mobile communication system has a mobile terminal, basestations, and a Radio Network Controller (RNC). In the case where drop of a frame occurs during data communication in Iub/Iur (between the basestations and the RNC), the RNC executes retransmission of an EDCH FP frame between the RNC and the basestations by transmitting a TN frame to the basestations to repair the drop of the frame without executing retransmission with the terminal device.

Abstract: Embodiments of methods for optimizing power savings in a wireless device by maintaining sleep in sub-frames of an extended Listen Window, in an I.E.E.E. 802.16m communication system. In one embodiment, the Listen Window is extended into the Sleep Window, wherein at least one sub-frame remains designated for sleep. The power savings may be used when HARQ retransmissions are scheduled or for VoIP transmissions and so forth.

Abstract: The present invention is directed to a method and system for broadcasting a message to selected devices. More specifically, the method and system identifies appropriate VoIP devices of a recipient client suitable for a broadcast message and transmits the broadcast message to the identified appropriate VoIP devices over a digital communication channel. The appropriate VoIP devices are selected in accordance with various constraints of broadcasting such as recipient client's preference, functionality and capability of the recipient VoIP device, broadcaster's bandwidth, a set of broadcasting rules, or the like. In order to identify appropriate VoIP devices or a recipient client, the information relating to the recipient client and VoIP devices may be exchanged using the digital communication channel.

Abstract: A telephone relay system enabling a terminal having multiple telephone numbers to originate and receive calls same as a terminal having only one telephone number is provided. When a connection management unit of an agent device receives a call request from a terminal device, it activates a terminal calling unit while designating a current telephone number and also activates a counterpart calling unit to establish a terminal-side connection between the current telephone number of the terminal device and the agent device and a counterpart-side connection between the agent device and the counterpart terminal. When an incoming call from the counterpart terminal arrives, the connection management unit establishes a counterpart-side connection corresponding to the incoming call, and activates the terminal calling unit while designating the current telephone number to establish a terminal-side connection.

Abstract: A serial buffer transports packets through queues capable of operating in a packet mode or a raw data mode. In packet mode, entire packets are stored in a queue. In raw data mode, packet header/delimiter information is not stored in the queue (only packet data is stored). Packets can be transferred out of a queue in response to a slave read request. The serial buffer constructs a packet header in response to the slave read request, and retrieves a specified amount of packet data from the selected queue. The serial buffer also transfers out packets as a bus master when a water level exceeds a water mark within a queue. The serial buffer constructs packet headers for these bus master transfers, which may be performed in a flush mode or a non-flush mode (in packet mode), or in a flush mode (in raw data mode).

Abstract: This disclosure describes techniques for transforming residual blocks of video data. In particular, a plurality of different transforms selectively applied to the residual blocks based on the prediction mode of the video blocks. At least a portion of the plurality of transforms are separable directional transform specifically trained for a corresponding prediction mode to provide better energy compaction for the residual blocks of the given prediction mode. Using separable directional transforms offers the benefits of lower computation complexity and storage requirement than use of non-separable directional transforms. Additionally, a scan order used to scan the coefficients of the residual block may be adjusted when applying separable directional transforms.

Abstract: One embodiment of the present method and apparatus for assisting a peer-to-peer connection between a first node and a second node includes receiving, at a third node, a request for connection assistance from one of the first and second nodes. The third node then connects to both the first node and the second node, receives the data from the first node and delivers the data to the second node. In this manner, data may be transferred between the first and second nodes even if the first and second nodes are unable to directly connect to each other (e.g., due to permanent or temporary limitations).

Abstract: A system that incorporates teachings of the subject disclosure may include, for example, a method for analyzing a wide frequency band with respect to signal power levels in specified narrow frequency bands, detecting narrow band signal power levels received in the specified narrow frequency bands, determining an average composite wideband power level from the narrow band signal power levels, and determining an adaptive threshold from the narrow band signal power levels for detecting narrow band interferers in the wide frequency band. Other embodiments are disclosed.

Abstract: Methods, apparatus, systems and computer program products are defined that provide multiple bindings in a Mobile Internet Protocol (MIP) network environment. The multiple bindings that are established are independent of one another, such that a forward link binding is decoupled from, or otherwise does not affect, a reverse link binding and vice versa. Multiple reverse link-only bindings may be established within an active route set for an access terminal. Additionally a single primary binding may be established that provides a forward link binding and reverse link binding. At any point in time, the access terminal may maintain only one primary binding.

Abstract: At least one substitute path is provided in place of a plurality of existing paths of a network to reallocate traffic carried by the plurality of existing paths. The total bandwidth needed to carry the traffic of the plurality of existing paths is determined. A proposed route is generated from the available links in the network. A portion of the bandwidth of a proposed route may be allocated to the needed bandwidth when the bandwidth of a proposed route is greater than or equal to the needed bandwidth. When the bandwidth of the proposed route is less than the needed bandwidth, at least one further route is generated, and the needed bandwidth is divided among the proposed route and the at least one further route such that a minimum number of further routes are generated.

Abstract: Systems for switching traffic include a physical machine running source and destination virtual machines (VMs). The source VM issues a data unit addressed to the destination VM. The physical machine has a physical network interface in communication with the VMs. The physical network interface transmits a sub-packet, which includes a partial portion of the data unit, over a network while a majority portion of the data unit remains at the physical machine. A network switch on the network receives the sub-packet transmitted by the physical network interface. The network switch performs one or more OSI Layer 2 through Layer 7 switching functions on the sub-packet and returns that sub-packet to the physical network interface. The physical network interface identifies the data unit stored in the memory in response to the sub-packet returned from the network switch and forwards the identified data unit to the destination VM.

Abstract: A user equipment is operated in a mobile communications system, wherein a network part of the mobile communications system is capable of operating in a synchronized mode or in an asynchronous mode. Operation includes recording timing information about a periodically occurring signal received from a neighboring cell. The recorded timing information is used in a blind detection process that ascertains whether the network part of the mobile communications system is operating in the synchronized mode or in the asynchronous mode by detecting at least whether the periodically occurring signal received from the neighboring cell occurred within a predetermined window of time of a corresponding periodically occurring signal received from a serving cell. The detected operating mode of the network part of the mobile communications system is used for controlling subsequent operation of the user equipment.
