Patent number: 10492190Abstract: A first one of a wireless communication device (22) and a base station (20) performs a method for applying a change to a configuration or state of a radio bearer. The radio bearer supports the transfer of data over a radio connection between the wireless communication device (22) and the base station (20) with defined data transfer characteristics. The method includes performing a handshake with a second one of the wireless communication device (22) and the base station (20) to agree on a time to synchronously apply the change at the wireless communication device (22) and the base station (20). The method also includes, in accordance with the agreement, synchronously applying the change at that time.Type: GrantFiled: November 18, 2016Date of Patent: November 26, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Waikwok Kwong, Alessandro Caverni, Bo Hellander, Patrik Karlsson, Fredrik Ovesjö, Jose Luis Pradas

Patent number: 10454827Abstract: A method performed by a network element in a communication network comprises inspecting traffic between a radio device and the communication network. The method also comprises, based on said inspecting, determining that the traffic is part of a TCP subflow of an MPTCP connection. The method also comprises, based on said inspecting, calculating a ratio of how much data is transmitted in the subflow in relation to the total amount of data transmitted in the MPTCP connection over a predetermined time period. The method also comprises observing that the calculated ratio is below a reference ratio. The method also comprises, based on said observing, performing an action for preventing congestion in the communication network.Type: GrantFiled: May 15, 2014Date of Patent: October 22, 2019Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Bo Hellander, Elinor Aminoff, Christofer Lindheimer, Martin Skarve, Jari Vikberg

Patent number: 8903396Abstract: A User Equipment (UE) and a mobile communications network node perform or handle inter frequency measurements. The technology prevents overloading the UE with frequency measurement processing by allowing different requirements for measurements, i.e., measurement performance requirements on different frequencies, i.e., cells. When ordering the UE to perform inter frequency measurements, two or more separate neighbor cell lists may be used. This allows a UE having a certain processor capacity to perform measurement control for more cells and frequencies, i.e., measurements on more than two non-used frequencies, without increasing the processing load of the UE.Type: GrantFiled: October 5, 2011Date of Patent: December 2, 2014Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Bo Hellander, Niilo Musikka

Publication number: 20130109368Abstract: A User Equipment (UE) is reconfigured to a state of a Radio Resource Control (RRC) state machine. The reconfigured UE informs the network not only that a current data session is completed, but also of the expected time to a next data session and/or the expected traffic volume for the next data session. In this way, the network has better information on which to base resource-related decisions.Type: ApplicationFiled: October 27, 2011Publication date: May 2, 2013Applicant: TELEFONAKTIEBOLAGET L M ERICSSON (publ)Inventor: Bo Hellander

Patent number: 8385948Abstract: In a method of improved positioning of user equipments in a telecommunication system comprising at least one user equipment in communication with a core network node via a radio access network node, in response to a user equipment positioning event for said at least one user equipment performing the following steps. Providing S10 user equipment identification data in the core network node for each at least one user equipment, the data comprising at least a parameter indicative of a type for the user equipment, a confidence reporting principle, a geographical reporting format type, and a positioning method, associated with said user equipment type. Providing S20 positioning information in the core network node from the radio access network node based on the positioning event. The positioning information comprising a geographical format representative of the geographic position of the user equipment, and a positioning method applied in at least the radio network node.Type: GrantFiled: December 18, 2008Date of Patent: February 26, 2013Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Karl Torbjörn Wigren, Bo Hellander

Patent number: 6445918Abstract: A method and system for reconnecting dropped calls in a mobile telecommunications network. Upon detecting a call drop of an ongoing call, a mobile station involved in the call transmits a call reconnect request to a target cell in the network. The target cell can be selected from a neighboring cell list received from a serving cell during the call. In response to the call reconnect request, a target switching node associated with the target cell locates the call and reconnects the mobile station to the call using a traffic channel in the target cell.Type: GrantFiled: November 1, 1999Date of Patent: September 3, 2002Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: Bo Hellander
