A method for performing load balancing of data flows from a user equipment (UE) between a first radio access network and a second radio access network, wherein the UE is attached to the said first radio access network, the method comprising providing preference data from the first radio access network to the UE representing radio related parameters, determining the presence of an access network discovery and selection function (ANDSF) of the UE, evaluating, at the UE, including using ANDSF if present, the preference data to determine if a data flow can be offloaded to the second radio access network, and on the basis of the evaluation, offloading a data flow of the UE from the first radio access network.

A method, in a radio communication system, for setup or modification of data flows between user equipment (UE) in dual connectivity with a primary node and a secondary node of the system, comprising switching a data path between the primary node and the secondary node by transmitting message data between the primary node and secondary node to establish a direct user plane path between the secondary node and a serving gateway (S-GW) of the system.

A method for load balancing among carriers within a wireless communication network, this method comprising the following steps—collecting information indicative of a user traffic profile, this user traffic profile being associated with a user equipment connected through a first carrier frequency to the wireless communication network; deciding on whether to offload the traffic of the user equipment from the first carrier frequency to a second carrier frequency on the basis of at least the information indicative of the user traffic profile.

A leaky repeater access node (LRAN) includes a first directional antenna and a second directional antenna to transmit and receive signals in at least one first frequency band, and a third antenna to transmit and receive signals in a second frequency band. The LRAN also includes first analog components to split a first signal received by the first directional antenna into a first portion and a second portion. The first analog components amplify the first portion and provide the amplified first portion to the second directional antenna. The first analog components also convert the second portion to the second frequency band and provide the converted second portion to the third antenna.

A method of small cell deployment is performed in response to an initialization request or a performance alarm. The method includes selecting an initial number (N) of small cell candidate locations of one or more feasible small cell locations for small cells on a three dimensional grid of nodes representation of an area of interest and determining, feasible M-sized small cell tuples having small cells that do not conflict with each other, wherein M has an initial value less than or equal to N. The method also computes at least one performance Key Performance Indicator (KPI) for a subset of the feasible M-sized small cell tuples, and searches for a first tuple of the subset of the feasible M-sized small cell tuples, the at least one performance KPI of the first tuple satisfying one or more constraints on the small cell deployment.

A method for interfacing a plurality of videoconferencing client devices the method comprising, in a computer server ( 5 ) connected to a client devices:—receiving a first client video stream ( 7 ) from the video routing client ( 4 );—tagging a video image of the first client video stream received from the video routing client;—sending, through a bidirectional communication channel ( 14 ), the first client video stream ( 21 ) to a mixing client ( 2 );—receiving, through the bidirectional communication channel with the mixing client, a mixed video stream ( 15 ) from said mixing client;—detecting in the mixed video stream received from the mixing client a video image portion which is different from the tagged video image of the first client video stream;—extracting the detected video image portion from the mixed video stream;—generating a second client video stream ( 23 ) from the extracted video image portion;—sending the second client video stream to the video routing client.

A transmission device includes a first connecting module for connecting a DC/DC power converter to a telephone wire line or to a CPE wire line, and a second connecting module between the telephone and CPE wire lines, a detection module configured to detect a power feeding request signal on the CPE wire line, and a switching module configured to controls the second connecting module in its open state, and send a power ready signal on the CPE wire line, and a not control the second connecting module and not send a signal on the CPE wire line in a standby-by state, so that a total power consumption of the detection and switching modules is lower than a threshold in a stand-by state and higher in the active state, and the detection module is configured to control the switching module in response to a detection of the power feeding request signal.

A user equipment method, user equipment and a computer program product are disclosed. The user equipment method comprises: determining a first indicator indicative of a potential throughput for a channel between the user equipment and a base station when using a network assist interference suppression scheme; determining a second indicator indicative of a potential throughput for the channel between the user equipment and the base station without using the network assist interference suppression scheme; calculating an effective indicator indicative of an effective potential throughput for the channel between the user equipment and the base station based on the first indicator and the second indicator; and transmitting the effective indicator to the base station. In this way, rather than transmitting only an indicator of the potential throughput when not using the network assist interference suppression scheme or only transmitting an indicator which indicates the throughput when using the network assist interference suppression scheme, instead an effective throughput is transmitted which may be based on both of these indicators and so is likely to be more stable. Also, by only transmitting a single throughput indicator, the need for additional signalling to carry those additional indicators is avoided, which enables an improved indicator to be provided using existing signalling.

In accordance with an embodiment, the vectoring controller is configured to iterate through successive crosstalk acquisition cycles and, within respective ones of the crosstalk acquisition cycles, to configure sequences of crosstalk probing symbols for transmission over the respective communication lines, to receive sequences of error samples as successively measured by respective receivers coupled to the respective communication lines while the sequences of crosstalk probing symbols are being transmitted, and to determine crosstalk estimates between the respective communication lines based on the sequences of error samples. The vectoring controller is further configured to randomize the successive sequences of crosstalk probing symbols used during the successive crosstalk acquisition cycles, and to iteratively configure the vectoring processor based on the successive crosstalk estimates.

An example method provides a method of determining access times and channels for a wireless communication device. One embodiment includes selecting, at a wireless communication device, one of a plurality of time intervals in a periodically repeating access cycle for transmission of an access signal based on an identification number identifying the wireless communication device, negotiating a preamble assignment for the selected one of the plurality of time intervals, and transmitting the access signal over an access channel in the selected one of the plurality of time intervals using a preamble corresponding to the preamble assignment.
