Patent number: 8041355Abstract: A method, terminal, and system for cell reselection are disclosed. The method includes: a terminal obtains a dedicated priority list from a first system; and performs cell reselection according to the dedicated priority list when the terminal camps on a cell of a second system. The corresponding terminal and system are also provided in other embodiments of the invention. According to an embodiment of the invention, the terminal performs cell reselection by using the dedicated priority list obtained from the first system so as to free the second system from establishing the dedicated priority list. Problems in the prior arts that establishment of the dedicated priority list causes too much increased signaling and too high costs for network upgrade are solved.Type: GrantFiled: November 29, 2010Date of Patent: October 18, 2011Assignee: Huawei Technologies Co., Ltd.Inventors: Michael Roberts, Johan Johansson, Boyun Xie, Min Huang

Publication number: 20090274050Abstract: An improved method and a communication means node implementing the method for load control in connection with a multimedia service transmission intended for multiple receivers over a wireless network are disclosed. The receivers in the wireless network are able to respond to requests communicated from an ordering entity by feeding back responses to a management entity in said wireless network. The feedback of these responses uses a different communication means, separate from said wireless network. This different communication means has limited communication resources. A transmission load caused in said different communication means by said feedback of said responses is according to the invention controlled by the different communication means itself.Type: ApplicationFiled: April 29, 2009Publication date: November 5, 2009Applicant: Huawei Technologies Co., Ltd.Inventors: Johan Johansson, Michael Roberts

Publication number: 20090268689Abstract: A method for handover in a telecommunication system is disclosed. The method determines a traffic time pattern in a handover situation where a user equipment is handed over from a source cell to a target cell in the telecommunication system. History information relating to a traffic time pattern used in the source cell by the user equipment being handed over is forwarded from a controller node of said source cell to a controller node of said target cell. In the target cell, a traffic time pattern to be used by said user equipment in said target cell after the handover is estimated by taking into consideration at least said history information.Type: ApplicationFiled: July 6, 2009Publication date: October 29, 2009Inventors: Yusun FU, Johan Johansson

Publication number: 20090147738Abstract: The method and arrangement according to the present invention relates to of scheduling and coding in communication systems utilizing automatic repeat request (ARQ) and/or multihop scheduling and forwarding. According to the inventive method the receiving nodes selectively stores received information, also overheard information, as a priori information and feed back information about their respective stored a priori information to a sending node. The sending node forms composite data packets by jointly encoding and scheduling multiple data packets, which composite data packets are transmitted to receiving nodes. Upon receiving a composite data packet the receiving nodes uses their stored a priori information in the process of extracting data for themselves from the composite data packets.Type: ApplicationFiled: July 7, 2005Publication date: June 11, 2009Inventors: Peter Larsson, Kai-Erik Sunell, Niklas Johan Johansson

Publication number: 20090036092Abstract: The present invention relates to a subscription-based measurement concept where the detailed parameters for a certain measurement report are set by a measurement provider, i.e. a radio base station, instead of the measurement requester. For this purpose the measurement provider “publishes” a certain set of measurements that controller units for radio resource management (RRM) can subscribe to. According to the present invention parameters of measurements are defined in detail in the measuring entity, i.e. the target radio base station, as opposed to being defined by the requesting entity, i. e. the RRM controller.Type: ApplicationFiled: February 12, 2007Publication date: February 5, 2009Inventors: Johan Johansson, Mattias Wahlqvist, Martin Israelsson
