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.

A method and terminal are disclosed for cell reselection. 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 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.

Apparatus and methods are provided for enhanced codec control. In one novel aspect, a method includes receiving a codec control command by a user equipment (UE) in a wireless network, determining if the recommended codec characteristic will be applied to a codec executing on the UE, and adjusting a characteristic of the codec executing on the UE based on the recommended codec characteristic. The UE is connected with a radio access network (RAN) and the codec control command includes a recommended codec characteristic. In another novel aspect, the recommended codec characteristic is a maximum bitrate. In another embodiment, the recommended codec characteristic is a type of codec. In yet another novel aspect, the recommended codec characteristic is a radio resource allocation command. In another novel aspect, the UE determines all available codec bitrates that can be performed by the UE and communicates the bitrates before receiving the codec control command.

A method of extended DRX paging includes a base station that transmits extended DRX configuration information and a User Equipment (UE) receives the extended DRX configuration from the base station. The UE determines a first number of frames that are included in a hyper-frame based at least in part on the extended DRX configuration information and selects a hyper-frame number. The hyper-frame number is based at least in part on the extended DRX configuration information. The UE maintains a hyper-frame count and the hyper-frame count is incremented after each hyper-frame. The UE then goes into sleep mode and the UE determines a wake up time before a standard DRX cycle that occurs during the selected hyper-frame. The UE may also determine a first wake up time and a second wake up time based on the selected hyper-frame number and synchronization error between a first cell and a second cell.

A method and an apparatus for detecting a radio network problem are disclosed. The method includes: when a radio link failure (RLF) problem occurs on a user equipment (UE) in a previous cell, a first base station controlling a new cell that a radio resource control (RRC) connection established with the UE receives problem information about the RLF problem sent by the UE, after the RRC connection is established, and the first base station sends the problem information to a second base station controlling the previous cell. In this way, the network side can automatically identify and detect the radio network problem which occurs on the UE, so that the network can perform self-adjustment and optimization, therefore improving the network performance and satisfying use requirements of users.

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.

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.

A method and device of sending Buffer Status Reports (BSRs) includes determining the type priority sequence of BSR by a user terminal, and selecting and processing one BSR based on the type priority.
