Abstract: A more efficient network can be achieved by leveraging an adaptive dejitter buffer. The dejitter buffer can be dynamically adjusted based off a network data analysis. A communication handover can be adjusted or shifted based on voice inactivity data related to a forecasted punctuation. The dejitter buffer memory/depth of a mobile device can also be adjusted in accordance with receiving a delay interruption length associated with another mobile device. Thereafter, the dejitter buffer memory can be filled with voice packet data to decrease a packet delay variation at the mobile device.

Abstract: Apparatus for use within an IP Multimedia Subsystem, IMS, network to handle Session Initiation Protocol, SIP, messages. The apparatus comprises a receiver for receiving a SIP message from a peer IMS node, and a SIP message inspector for inspecting a P-Charging-Vector, PCV, header within a received SIP message in order to detect the presence within the PCV header of a parameter and associated handling determinator. The apparatus further comprises a SIP message handler for determining, on the basis of a handling determinator and without reference to said associated parameter, an action or actions to be applied to said parameter and associated handling determinator.

Abstract: Provided are a method and apparatus for transmitting a reference signal in a multi-antenna system. A terminal generates a plurality of reference signal sequences to which cyclic shift values different from each other are allocated, generates an orthogonal frequency division multiplexing (OFDM) symbol to which the plurality of reference signal sequences are mapped, and transmits the OFDM symbol to a base station through a plurality of antennas. The respective cyclic shift values allocated to the respective reference signal sequences are determined on the basis of a parameter n indicated by a cyclic shift field transmitted from a physical downlink control channel (PDCCH).

Abstract: A method and apparatus for selecting a bandwidth option for a cell in a network are disclosed. For example, the method obtains, for the cell, network traffic data for a geographical area, and a physical characteristic of an antenna in the geographical area, determines busy time data traffic from the network traffic data, determines, for the cell, a cell range from the physical characteristic of the antenna, selects a bandwidth option from a plurality of bandwidth options, and determines an average throughput in accordance with the bandwidth option that is selected and the cell range.

Abstract: A method for routing data between at least one guided vehicle and a ground network, wherein said vehicle moves on a track between at least a first and a second communication terminal arranged on the ground along the track. The terminals are capable of exchanging data streams between a ground network and at least one routing module onboard the vehicle.

Abstract: The invention relates to a method for managing multicast traffic in a data network, and network equipment using said method. Hosts receive from a network interface of a router traffic sent by sources in a multicast group. The hosts and the router communicate with one another by using a multicast host-router communications protocol by which the hosts send to the router messages to request multicast traffic from sources in a multicast group. The router receiving one of said messages obtains in said message identifying data which identify the host that has sent said message, and said router stores in specific records for each network interface of the router, host and multicast group information about the sources the traffic of which has been requested by said host in said messages sent to the router.

Abstract: A method and apparatus for bridging network protocols is disclosed. In one embodiment, a data frame is received and stored in a dual-port memory queue by hardware logic. An embedded processor is notified of the data frame once a programmable number of bytes of the data frame have been received and stored. Once notified, the embedded processor may then undertake to read the data frame from the memory queue while the hardware logic is still writing to the memory queue. In one embodiment, the processor may then translate the data frame's protocol and begin transmitting it out over a network connection, all while the data frame's payload is still being received.
