Abstract: A method and apparatus for handling a call transfer from a circuit switched access network to a packet switched access network. A Mobile Switching Center Server receives a notification that a call for a terminal requires handover from a circuit switched access network to a packet switched access network. The MSC Server determines whether the terminal is currently registered in an IMS network and/or whether the MSC Server is registered such that it can perform handover from the circuit switched access network to the packet switched access network. If so, then return Single Radio Voice Call Continuity is invoked to perform a handover of the call from the circuit switched access network to the packet switched access network. If not then the MSC Server invokes error handling procedures.

Abstract: A method and an apparatus for reporting buffer status are provided. The method includes: obtaining multiple Transport Blocks (TBs) from a base station within one Transmission Time Interval (TTI); selecting a TB compliant with a condition of transmitting a Buffer Status Report (BSR) among the multiple TBs; and bearing a BSR of a Logical Channel Group (LCG) and a Control Element (CE) sub-header of the BSR onto the selected TB and sending the TB to the base station. In this way, a UE can make full use of the padding bits of the obtained multiple TBs, and report the buffer status flexibly.

Abstract: A method in a radio network node for communicating with a user equipment (UE) during communication between the radio network node and a radio base station in a radio communications network. The radio network node serves the UE within a cell and communicates with the radio base station and the UE over a frequency spectrum in a time division duplexing configuration. The radio network node sets up a first connection over a first part of the frequency spectrum to the radio base station, and a second connection to the UE over the first or a second part of the frequency spectrum. The second part of the frequency spectrum is solely used for communication with UEs within the cell. The radio network node then communicates simultaneously with the UE and the radio base station over respective connections in a time slot of a reference time configured by the radio communications network.

Based on comparisons made with the WCD location coordinates, if the WCD is within range of a wireless local area network (WLAN) access point and remains stationary for a preset time interval, a wireless local area network (WLAN) radio interface may be activated within the WCD to connect to the WLAN via the access point.

Abstract: In general, techniques are described for defining an interface to a network router software infrastructure that allows developers to dynamically extend a routing protocol executed by the network router to distribute data throughout the routing domain for use with custom applications. In some examples, a routing protocol process executing on a control plane of a network device may expose an interface, such as an Application Programming Interface (API), that defines methods and parameters for extending the operation of a routing protocol executed by the routing protocol process.

Abstract: In a communications apparatus, a communication controller transmits and receives signals on any of plural channels. A channel switching controller is responsive to channel switching information selectively defining plural reception-waiting periods using the channels to alter a channel to be used by the communication controller. A neighboring node channel controller exchanges channel switching information with other nodes to manage the channel switching information received from the other nodes. When transmitting transmission signals, a transmission controller refers to the channel switching information of the other nodes, and controls repetitive transmission of the transmission signals on the channel thus searched for.

A SOAPAction header and SOAP envelope can be included in a SIP message to identify a requested service. The SIP message recipient can parse out the SOAP envelope and forward same to a corresponding Web Service.

Abstract: A relay wireless communication device is discovered using probe request. A source device that intends to transmit one or more frames to a destination device transmits the probe request to request a probe response from one or more potential relay devices. A relay device transmits a probe response to the source device when the relay device may operate to forward the one or more frames from the source device to the destination device. The relay device employs one or more considerations to determine its eligibility to serve as relay for the source and destination devices. The source device selects one of the potential relay devices based on their provided probe responses. The source device may select an optimal relay device based upon two or more received probe responses.

Abstract: A radio communication system includes a plurality of mobile station apparatuses and a base statement apparatus. Each of the mobile station apparatuses selects the lowest number and the second lowest number of control channel elements (CCEs) in which downlink allocation information is detected, and obtains two combinations, to be applied to transmission antennas, of a physical resource block (PRB), a cyclic shift amount, and an orthogonal code sequence in the time domain, on the basis of values by adding the numbers of CCEs to an offset value broadcast by the base station apparatus. Each of the mobile station apparatuses spreads pilot signals using spread codes based on the two combinations, arranges the spread pilot signals in PRBs corresponding to the signals, and transmits the signals through the transmission antennas.

The method comprises: a target HeNB which a user equipment (UE) is to be handed over notifies a Mobility Management Entity (MME) of the tunnel information through a handover acknowledgement message, a handover notification message or a path converting request message; and the MME notifies a fixed network of the received tunnel information through an Evolved Packet Core (EPC) gateway and a Policy and Charging Rules Function entity (PCRF). With the present disclosure, policy interworking between a mobile network and the fixed network can be implemented, and the Quality of Service of the HeNB can be ensured.

Abstract: This invention relates to methods and devices for compensating for path asymmetry, particularly with reference to time and frequency synchronization. The invention has particular application where time and frequency synchronization over packet networks using, for example, the IEEE 1588 Precision Time Protocol (PTP) is being carried out. Typically communication path delays between a time server (master) and a client (slave) are estimated using the assumption that the forward delay on the path is the same as the reverse delay. As a result, differences between these delays (delay asymmetries) can cause errors in the estimation of the offset of the slave clock from that of the master. Embodiments of the invention provide techniques and devices for compensating for path delay asymmetries that arise when timing protocol messages experience dissimilar queuing delays in the forward and reverse paths.

Abstract: Disclosed are a terminal device for receiving a signal in a wireless communication system for supporting a plurality of component carriers and a method thereof. In the terminal device for receiving the signal in the system for supporting the component carriers, a receiver receives a Physical Downlink Control Channel (PDCCH) including control information of a first type component carrier from a base station or a relay. A processor performs a decoding operation or controls an operation in a slip mode on the basis of control information included in a PDCCH in a second type component carrier after a time corresponding to a particular time offset value passes from a transmission time point of the PDCCH.

Abstract: Packet processing is broken into two or more stages. In particular, the network processing unit 26 performs a first stage of packet processing related to packet forwarding and packet modification, and then performs a second stage of packet processing unrelated to packet forwarding and packet modification. Example processes unrelated to packet forwarding and packet modification may include state updates on the network element, such as statistics counter updates, stateful flow tracking, IPFix processing, MAC learning, and other processes important to operation of the network element, but which do not affect the appearance of the packet (e.g. packet format) and which do not affect the forwarding decision of the packet. Once the first stage of packet processing related to packet forwarding and packet modification has been completed, the flag associated with the packet is cleared in the scoreboard, to allow the packet to be transmitted from the reorder queue.

Abstract: Rather than using a large number of transceivers (transmitter/receiver pairs) operating in parallel, Access Points with multiple channels are used to aggregate, or stack, transmitted response communications, e.g., transmitting multiple acknowledgements (ACKs) in a single packet to one or more sources of received packets. The method includes sending on a plurality of channels, by each of a plurality of respective first nodes, a communication to a second node, receiving on the plurality of channels, by the second node, the communication from each of the plurality of first nodes and sending, by the second node, a transmission that contains a response to each communication that was successfully received from each of the plurality of first nodes. The response to each of the plurality of first nodes is part of a single message sent by the second node.

The base station includes a repetition unit configured to repeat the broadcast channel, after the broadcast channel is channel-coded, for the predefined number of times to generate multiple broadcast channels; and a signal waveform changing unit configured to process the generated broadcast channels such that the processed broadcast channels have different signal waveforms. Positions of the broadcast channels in the order of transmission in the predetermined cycle are associated with the signal waveforms of the broadcast channels.

Abstract: A system may receive a connection request, from a user device, that includes information identifying a particular application; identify that the particular application is associated with a group of classes of traffic; establish a group of bearer channels that are associated with the group of classes of traffic, the group of bearer channels being associated with a group of different levels of quality of service (“QoS”); process, via a first bearer channel and according to a first level of QoS, first traffic associated with the user device and the particular application; and process, via a second bearer channel of the group of bearer channels, according to a second level of QoS, second traffic associated with the user device and the particular application, the second bearer channel being different from the first bearer channel, and the second level of QoS being different from the first level of QoS.

Abstract: A method and system for managing broadcast of notifications indicating whether system information has changed, so as to enable served devices to determine when to read and store updated system information. A radio access network tracks changes in system information on a per wakeup cycle basis, so as to determine whether system information has changed since a last instance of broadcasting such a notification in a particular wakeup cycle. If system information has changed, the network responsively broadcasts an indication that system information has changed, so as to cause devices operating on that wakeup cycle to read and store the updated system information. Whereas, if system information has not changed, the network responsively broadcasts an indication that system information has not changed (or forgoes broadcasting an indication that system information has changed), so that devices operating on that wakeup cycle can avoid reading and storing the system information.
