20090161593 | Wireless Multicast for Layered Media - The present invention relates to a method and arrangement for optimizing data rates in communicating multicast data, the method comprising the steps of: obtaining available data rates corresponding to a user station; computing optimal data rate within each access network cell; and controlling the data rate for each data packet at each access network cell. | 06-25-2009 |
20100061231 | MULTI-DOMAIN NETWORK AND METHOD FOR MULTI-DOMAIN NETWORK - Each domain of a multi-domain network collects intra-domain routing information relating to that domain and makes a reduced view of that information available to other domains of the network, and in which each domain of the network uses its own intra-domain routing information together with the reduced-view routing information from the other domains to form a logical view of the network so as to enable that domain to make an end-to-end route selection decision. | 03-11-2010 |
20100202456 | Method and Apparatus for Stream Adaption in a Packet Switched Network - A method is disclosed for use in a packet switched network, comprising carrying descriptor information relating to options for stream adaptation, for example media stream adaptation, in the packet switched network using at least one of the Next Step in Signalling, NSIS, and Resource Reservation Protocol, RSVP, signalling protocols. Carrying the descriptor information may comprise receiving (S | 08-12-2010 |
20100232340 | Method of Transmitting MBMS Data in an E-UTRAN-System - In an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) system Multimedia Broadcast Multicast Service (MBMS) data is transmitted as layered data together with control information comprising information enabling a User Equipment to reconstruct the layered MBMS data. | 09-16-2010 |
20110116491 | IMPROVING TRANSMISSION OF MEDIA STREAMS OF BROADCAST SERVICES IN A MULTIMEDIA BROADCAST TRANSMISSION SYSTEM - In multimedia broadcast transmission a system a method and a device for improving transmission are provided. The optimization is achieved by the combination of a Virtual Time-Slice (VTS) solution within a broadcast service in which time-slice corresponding to a layered broadcast service and a feedback channel through a wireless access network. The VTS allows the system to set the layer content within a broadcast service time-slice according to the user's feedbacks. An optimization algorithm selects the appropriate number of enhancement layers mapped into VTSs. The users provide feedback information based on their own receiving capabilities or on subscription limitations. If a time-division multiplex multimedia broadcast network, e.g. DVB-H network is deployed next to the wireless access network, e.g. a 3G network, then these feedback information can be signaled via this network. | 05-19-2011 |
20130121161 | Apparatus and Method in a Telecommunications Network - An entity in a telecommunications network, for example a user equipment, determines a threshold value relating to a channel switching parameter that is being used by the telecommunications network to trigger a channel switching operation, and uses this threshold value and monitored traffic information to prevent a channel change from occurring, i.e. to maintain channel occupancy. A network node is adapted to remove additional traffic that has been generated by an entity in the telecommunications network to maintain channel occupancy. | 05-16-2013 |
20140099949 | METHODS AND ARRANGEMENTS FOR HANDLING AN IDENTIFICATION OF AN AVAILABLE COVERAGE IN A CELLULAR NETWORK - A method in a base station for handling an identification of an available coverage in a cellular network is provided. The base station serves a first cell in the cellular network. The base station identifies a coverage of a second cell in the cellular network. When the second cell is in the active mode it overlaps a portion of the first cell. When the second cell is in the sleep mode, the base station transmits via the first cell a message to a user equipment located in the portion. The message comprises an indication of the coverage of the second cell, thereby enabling the user equipment to identify the coverage of the second cell as an available coverage for handling of an upcoming data transmission. | 04-10-2014 |
20140301261 | Methods, Device and Node for DRX of Data - A method performed by a radio communication device for discontinuous reception, DRX, of data from a radio network node is disclosed. When information, indicating that data is scheduled to the radio communication device in a DRX cycle, is received ( | 10-09-2014 |
