Abstract: A video telecommunication connection is established via a landline telecommunications network and an IP multimedia subsystem telecommunications network using a media gateway control function of at least one Internet multimedia-media gateway device in the IP multimedia subsystem telecommunications network. An H.223 multiplex level usable for a telecommunication connection is exposed to an H.223 protocol negotiation, in carrying out an H.245 protocol negotiations for setting up the H.223 protocol negotiations connection for a telecommunication connection. A media gateway control function device is informed when the H.223 logic channels are open by H.245 signaling, thereby enabling the Internet multimedia-media gateway device of the IP multimedia subsystem telecommunications network to carry out at least part of the setup.

Abstract: In the present invention, disclosed is a method for a terminal, which receives a downlink signal from a first base station and transmits an uplink signal to a second base station, transmitting a sounding reference signal (SRS) in a wireless communication system. More specifically, the method comprises the steps of: receiving from the first base station downlink control information including a triggering message of a first SRS; determining transmission power of the first SRS on the basis of the downlink control information; and transmitting the first SRS to the first base station with the transmission power that is determined, wherein a transmission power control command field, which is included in the downlink control information, is applied to a closed loop parameter for determining the transmission power of the first SRS.

Abstract: Circuitry to provide in-order packet delivery. A packet descriptor including a sequence number is received. It is determined in which of three ranges the sequence number resides. Depending, at least in part, on the range in which the sequence number resides it is determined if the packet descriptor is to be communicated to a scheduler which causes an associated packet to be transmitted. If the sequence number resides in a first “flush” range, all associated packet descriptors are output. If the sequence number resides in a second “send” range, only the received packet descriptor is output. If the sequence number resides in a third “store and reorder” range and the sequence number is the next in-order sequence number the packet descriptor is output; if the sequence number is not the next in-order sequence number the packet descriptor is stored in a buffer and a corresponding valid bit is set.

The training information is then used to propagate node information to neighboring data vectors, which generates an indication of faulty nodes or an indication of a normal transmission path.

Abstract: A base station may provide wireless service on an air interface that defines different mutually exclusive groups of random access channel (RACH) instances for different uses. In one example, the air interface may define a first group of RACH instances having groupings of preambles for designating a value of a characteristic, and define a second group of RACH instances that does not have groupings of preambles. As another example, the air interface may define a first group of RACH instances that has groupings of preambles for designating a value of a first characteristic, and define a second group of RACH instances that has groupings of preambles for designating a value of a second characteristic. The base station may then differentially handle random access requests based on whether the base station receives a preamble in a RACH instance of the first group or rather the second group.

Abstract: A method for determining location of a failure causing degradation of a service in a mobile communications network is disclosed. Service trajectories for the mobile terminals are determined (104) by correlating earlier obtained movement trajectories (102) of individual mobile terminals with service session records of the mobile terminals. In the next step distributions of the service trajectories of mobile terminals with degraded service are determined and then a network element around which the service trajectories converge is identified (108) as the location of the failure. An apparatus, a communications network and a computer program product are also disclosed.

Abstract: Methods and apparatus for selecting digital (network) interface technology for programming and data delivery over, e.g., a content-based network. In one embodiment, the network comprises an HFC cable or satellite network that includes a server process interfacing with a plurality of customer premises equipment (CPE), and/or associated client devices, each having different capabilities profiles. The server determines the one or more capabilities possessed by the CPE, and evaluates one or more program or content choices for possible delivery to that CPE based on its profile. The server generates a list of programs or content based on this evaluation, and transmits this list to the CPE, which displays the list for viewing by a user. The user is therefore offered a list of available content that is compatible with their specific configuration.

Abstract: Architecture that facilitates the virtual specification of a connection between physical endpoints. A network can be defined as an abstract connectivity model expressed in terms of the connectivity intent, rather than any specific technology. The connectivity model is translated into configuration settings, policies, firewall rules, etc., to implement the connectivity intent based on available physical networks and devices capabilities. The connectivity model defines the connectivity semantics of the network and controls the communication between the physical nodes in the physical network. The resultant virtual network may be a virtual overlay that is independent of the physical layer. Alternatively, the virtual overlay can also include elements and abstracts of the physical network(s). Moreover, automatic network security rules (e.g., Internet Protocol security-IPSec) can be derived from the connectivity model of the network.

Abstract: A method and apparatus for transmitting ACK/NACK information in a wireless communication system are disclosed. In accordance with a method for transmitting ACK/NACK information, an ACK/NACK signal of downlink transmission in a downlink subframe set is transmitted in a single uplink subframe. In this case, if a first physical uplink control channel (PUCCH) format is established by a higher layer for a downlink receiver, and if one physical downlink shared channel (PDSCH) is transmitted in a downlink subframe set, the ACK/NACK information can be transmitted using a second PUCCH format on PUCCH resources established by a higher layer for the second PUCCH format.

Abstract: A switch receives a state change notice from a server via a port, the state change notice indicating that the state is changed. When a port receives a state change notice, the switch shifts the state of the port to a waiting-for-driver-start-up state to prevent execution of a process that corresponds to a signal that is received from the server. When the port receives, after it is shifted to the waiting-for-driver-start-up state, a signal that satisfies a predetermined condition from the server, the switch releases the port from the waiting-for-driver-start-up state.

Abstract: Handling network data packets classified as being high throughput and low latency with a network traffic management device is disclosed. Packets are received from a network and classified as high throughput or low latency based on packet characteristics or other factors. Low latency classified packets are generally processed immediately, such as upon receipt, while the low latency packet processing is strategically interrupted to enable processing coalesced high throughput classified packets in an optimized manner. The determination to cease processing low latency packets in favor of high throughput packets may be based on a number of factors, including whether a threshold number of high throughput classified packets are received or based on periodically polling a high throughput packet memory storage location.
