Publication number: 20150358883Abstract: The present disclosure concerns movements, such as handovers, of user equipments (UEs) 120a-e from one radio cell 130a to another radio cell 130b. Disclosed herein are methods as well radio network nodes 110a, 110b. A radio network node 110a, 110b may, for example, select the most suitable UE(s) 20a-e to move from a source radio cell 130a to a target radio cell 130b in case the traffic load in the source radio cell 130a is below or equal to the traffic load of the target radio cell 130b. Hereby it is made possible to improve the resource utilization.Type: ApplicationFiled: January 11, 2013Publication date: December 10, 2015Inventors: Samuel AXELSSON, Rasmus AXÉN, Sven EKEMARK, Olof Axel GRANBERG, Walter MÜLLER, Parisa PAKNIAT

Publication number: 20150207700Abstract: A method and network node (400) for supporting evaluation of performance of a radio network. The network node employs carrier aggregation with multiple carriers used in corresponding multiple cells (Cell 1, Cell2, Cell 3). The network node retrieves (4:1) statistical information regarding utilization of radio resources, wherein the statistical information indicates secondary cell use of radio resources in a particular cell. The network node reports (4:5) the statistical information to an Operation and Maintenance, O&M, node (404), thereby enabling the O&M node to use the statistical information for evaluating (4:6) how a measured performance of the radio network is related to secondary cell usage.Type: ApplicationFiled: September 27, 2013Publication date: July 23, 2015Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: Per Elmdahl, Samuel Axelsson, Rasmus Axén, Fredrik Gunnarsson

Publication number: 20100115588Abstract: The present invent ion relates to a mobile advertisement system (100), a method and an application server (40) used to prevent user equipments (10) hosting a forged client 5 application or client software to get access and to hold an external data network connection. According to the present invention, an application server (40) is adapted to receive from the core network (20) of the advertisement system (100) a message comprising an end user identification number (e.g. MSISDN). The application server is further configured to trigger an advertisement confirmation timer which expects to receive an advertisement display confirmation message from the client of the user equipment (10). Upon the timer expiring, the application server (40) request the core network (20) to disconnect the user equipment thereby preventing the user equipment hosting a forged client application to get access and to hold a external data network connection.Type: ApplicationFiled: March 26, 2007Publication date: May 6, 2010Applicant: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Hanna Johannesson, Saswat Panigrahi, Emil Fengpei Zhang, Samuel Axelsson
