Publication number: 20240070289Abstract: Software is commonly built from a package of software packages, such as open-source packages. A package may require a number of interdependent packages, any one of which may have a security vulnerability. However, the dependencies between packages are often version specific and merely upgrading a package to the newest, or newest non-vulnerable, version may break a dependency and cause the software to be unbuildable (e.g., fail to compile or link) or, if built, faulty. By mapping dependencies to non-vulnerable versions a graphical representation may be built having one or more root-to-leaf paths identifying all the required packages by compatible version but exclude any vulnerable versions. The package may then be built to ensure the resulting software is both internally compatible between packages and absent known security vulnerabilities.Type: ApplicationFiled: August 25, 2022Publication date: February 29, 2024Applicant: MICRO FOCUS LLCInventors: Emil Wareus, Viktor Pettersson, Carl Ternby

Patent number: 11611889Abstract: Disclosed is a method for improving system performance in a wireless communication network comprising one or more network cells. Each network cell comprises one or more transmission points transmitting cell specific information. The method comprises determining (201, 401) whether a first TRxP comprised in a first network cell fulfills a utilization criterion. When it is determined that the first TRxP fulfills the utilization criterion (202, 401) the method further comprises gathering (204, 403) utilization statistics associated with the first TRxP and/or with the first network cell, evaluating (205, 404) the gathered utilization statistics and determining (206,405), based on the evaluated utilization statistics, whether moving the first TRxP to a second network cell will improve overall system performance of the wireless communication network. Also disclosed are arrangements, transmission points, radio control functions and computer program products.Type: GrantFiled: December 6, 2017Date of Patent: March 21, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Niclas Palm, Emil Pettersson, Jan Wichert

Publication number: 20220312453Abstract: A radio base station, RBS (10) of a wireless communication network indicates to a wireless device (14, 18, 20) where in the time and/or frequency domain to perform radio quality measurements. If the RBS (10) determines that one or more wireless devices (14, 18, 20) (including those that are idle) are in risk of performing deteriorated quality measurements, it refrains from scheduling beamformed downlink data in the time/frequency region where the wireless devices (14, 18, 20) perform quality measurements when the reference signals (e.g., Cell Specific Reference Signals, or CRS) are broadcast. This avoids deterioration of the RSRQ due to beamforming gain, and allows existing legacy features that rely on RSRQ to continue to function as originally intended. The restriction is only on beamformed data—the transmission of non-beamformed data in the relevant bandwidth is already accounted for in the use of RSRQ measurements.Type: ApplicationFiled: September 11, 2019Publication date: September 29, 2022Inventors: Emil Pettersson, Niclas Palm

Patent number: 9003051Abstract: Mechanisms are provided to manage media stream transmissions at a content server. A content server detects that a user on a device such as a mobile device has stopped playing a live media stream. The content server maintains information associating the user with the media stream and time information. When the content server detects that a user wishes to resume playing a media stream, the user can continue viewing the media stream from where stoppage occurred. In many instances, the content server stores many hours of live media stream data and allows a user to select a particular starting point.Type: GrantFiled: April 11, 2008Date of Patent: April 7, 2015Assignee: MobiTV, Inc.Inventors: Kent Karlsson, Emil Pettersson, Anders Ödlund, Mesut Yousseinof, Thomas Matsson
