Abstract: Network nodes in a source and a target communication system, and methods therein for supporting hand over to the target communication system, of a mobile terminal supporting Packet Switched-to-Circuit Switched, PS-to-CS, hand over. The method in the source communication system comprises, when requesting resources for hand over of a mobile terminal engaged in a conversational call to a target node in the target communication system, signaling a first request for PS resources to the target communication system, indicating a bearer B, used for the conversational call, and further signaling a second request for CS resources to the target communication system, indicating the bearer B. Thereby, the target communication system is enabled to decide whether a PS-to-CS HO or a PSHO of the bearer B should be performed.

Abstract: An integrated circuit with two operating modes is described. During a first operating mode, a de-multiplexer selectively couples information received via a common set of pads to first control logic, which decodes the information based on a first serial-interface technique. Moreover, during a second operating mode, the de-multiplexer selectively couples a first portion of the information to the first control logic and a second portion of the information to second control logic, which decodes the second portion based on a second serial-interface technique. By facilitating time-domain de-multiplexing of two similar serial-interface techniques, the integrated circuit can overcome the constraints imposed by a low or limited pin count.

Abstract: Systems and methods for buffering or delaying data packets to facilitate optimized distribution of content associated with the data packets are disclosed. Data packets sent from content providers may be received by a service provider, where information associated with the data packets may be identified. The identified information may be used to associate the data packets with an intended destination for the data packets and identify a type of the data packets, such as a video data packet. Video data packets (and other data packets) may be buffered or delayed such that more time-critical data packets may be accelerated into one or more QAM channels carrying the content. The delayed data packets may be time-sliced into the one or more QAM channels, which may displace empty slots or gaps that may waste bandwidth associated with the QAM channels.

Abstract: A channel selection circuit in a serial audio communication device provides channel selection for insertion or extraction of data to or from a multiplexed serial data stream without the requirement of extra channel selection inputs. The channel selection circuit has multiple counters structured such that each counter represents a channel of the serial data stream. The input of each counter receives one of the multiple synchronizing timing signals. The input of the designated counter receives one timing signal that has the greatest frequency. The remaining counters receive the word select timing signals for determining which channel is being selected. A ready output of each counter is a channel indicator in communication with multiple signal selection circuits for selecting the multiple timing signals to be transferred to a data processing device for inserting or extracting data to or from the multiplexed serial data stream.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and device for transmitting uplink control information when a plurality of cells are configured in a wireless communication system, the method comprising the steps of: generating a UCI; and determining a PUCCH resource for transmitting the UCI. If the reception response information and channel state information are triggered in the same subframe, only a first UCI generated from the reception response information is transmitted through a first PUCCH. If the reception response information and scheduling request information are triggered in the same subframe, a second UCI generated by jointly coding the reception response information and the scheduling request information is transmitted through a second PUCCH. The resource used for a reference signal for demodulating the first or second PUCCH is allocated in consideration of the UCI transmitted on PUCCH.

Abstract: Systems and methods providing uplink coordinated multi-point (CoMP) communication are shown. A second cell may identify at least one first UE communicating with a first cell and capable of causing high uplink interference to the second cell. The second cell may estimate uplink interference from the at least one first UE at the second cell. The second cell may estimate uplink interference on specific resources. For example, the second cell may determine resources assigned to the at least one first UE for data transmission to the first cell (e.g., using pre-scheduling information provided by the first cell) and estimate uplink interference from the at least one first UE on the resources assigned to the at least one first UE. The second cell may schedule at least one second UE for uplink data transmission to the second cell based on the estimated uplink interference from the at least one first UE.

Abstract: A virtual extensible local area network (“VXLAN”) system includes servers having VXLAN tunnel end points (“VTEP”) and virtual machines (“VMs”), multiple routers to transmit network data using bidirectional groups (“BIDIRs”) and rendezvous points (“RPs”), and an associated management and provisioning entity (“MPE”) adapted to arrange BIDIRs dynamically based upon network traffic such that traffic is more evenly distributed across the VXLAN. Some of the routers can be preconfigured as potential RPs, and the MPE can activate and deactivate these routers to and from RP status as needed. The MPE creates and rearranges BIDIRs based upon volume thresholds of traffic being reached in BIDIRs, such as by splitting overloaded BIDIRs. Network traffic can be monitored by VTEPs and RPs.

Automatically providing the first indication that the additional bandwidth is available includes providing the first indication to at least the sender. Finally, the method includes obtaining a second indication, the second indication being arranged to indicate whether the second amount of bandwidth may be accommodated with respect to the path.

Abstract: Traditional computer networks have been designed with the need for highly reliable packet delivery. This is largely handled by a centrally managed simple send-acknowledge protocol. In a highly dynamic mesh network, these methods are inadequate to ensure the most reliable packet delivery. This invention uses the natural redundancy of routes in a mesh and other techniques to increase the reliability of a network, even as the paths to any given node are dynamic in nature.
