Abstract: 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.

Abstract: Method, apparatus and systems are provided for key derivation. A target base station receives multiple keys derived by a source base station, where the keys correspond to cells of the target base station. The target base station selects a key corresponding to the target cell after obtaining information regarding a target cell that a user equipment (UE) is to access. An apparatus for key derivation and a communications system are also provided.

Abstract: Embodiments of the present invention relate to the field of communications technologies, and disclose a data transmission method and a device, to reduce a quantity of TCP-layer ACK packets transmitted on a radio air interface link between a first device and a second device, thereby reducing consumption of radio air interface link resources and improving transmission efficiency of radio service data. A specific solution is as follows: obtaining, by a first device, a TCP-layer ACK; and intercepting the TCP-layer ACK if a TCP-layer data packet corresponding to the TCP-layer ACK is a TCP-layer data packet that is obtained by the first device after the first device parses a link layer data packet received through a radio air interface link by the first device, and the TCP-layer ACK satisfies a preset condition. The present invention is applied to a data packet transmission process based on a TCP connection.

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.
