  • Patent number: 8996003
    Abstract: A method, terminal, system and computer readable medium for cell reselection are disclosed. When in a cell of a Long Term Evolution (LTE) system, the terminal receives a message from the LTE system. The message includes a dedicated priority list for the cell reselection. When the terminal camps on a cell of a non-LTE system, the terminal performs inter-system cell reselection in accordance with the dedicated priority list before a valid time of the dedicated priority list expires. With the discloses method, terminal and system, the problems of establishing a dedicated priority list causes too much increased signaling and too high costs for network update in the prior art when perform inter-system cell (re)selection are effectively resolved.

  • Publication number: 20140348133
    Abstract: 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.

  • Publication number: 20140194123
    Abstract: A system, base station and method are disclosed for detecting a radio network problem. For a handover failure occurs on a user equipment (UE), a first base station receives, problem information about the occurred handover failure from the UE, after a radio resource control (RRC) connection is reestablished or established between the UE and a cell controlled by the first base station. The first base station then transmits the received problem information to a second base station controlling a cell where the handover failure occurs. In this way, the network side can automatically identify and detect the handover failure. As such, the network can perform self-adjustment and optimization, therefore improving the network performance and satisfying use requirements of users.

  • Patent number: 8626166
    Abstract: 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.

  • Patent number: 8620895
    Abstract: During a data-access technique, a query that is associated with an organizational accounting code is used to generate a set of queries for business databases. In particular, when generating the set of queries, the organizational accounting code is mapped to a set of database-specific accounting codes using a reclassification list. After receiving answers to the set of queries (which are associated with the set of database-specific accounting codes) from the business databases, the answers are presented to the user. In this way, the user can access the business databases, which may have incompatible database-specific accounting codes, from a single environment with little or no additional effort or expense.

  • Patent number: 8605642
    Abstract: 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.

  • Patent number: 8412197
    Abstract: 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.

  • Patent number: 8340002
    Abstract: 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.
