  • Patent number: 9516536
    Abstract: A method and device of sending Buffer Status Reports (BSRs) are provided herein. The method includes: determining the type priority sequence of BSR by a user terminal, and selecting and processing one BSR based on the type priority. A user device is also provided. The provided method and device may reduce resource waste because there is no situation that at least two BSRs sending processes are triggered at one time and at least two BSRs are sent at one time.

  • Publication number: 20160286453
    Abstract: A method and terminal are disclosed for cell reselection. In the disclosure, the terminal obtains a dedicated priority list and a valid time of the dedicates priority list for cell reselection from a first communication system, such as a Long Term Evolution (LTE) system, when the terminal is in a cell of the fists communication system. In case that the the terminal camps on a cell of a second communication system, such as a non-LTE system (for example, a UMTS system), and before the valid time expire, the terminal performs cell reselection using the dedicated priority list.

  • Patent number: 9247493
    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.
