This disclosure relates to techniques for performing radio link monitoring and cell searching when moving at high speeds. A movement speed of a wireless device may be determined. When performing a cell search, the manner of the cell search may depend on the movement speed of the wireless device, potentially including cells that are associated with high movement speed being more highly prioritized when the wireless device is determined to be at a higher movement speed than when the wireless device is determined to be at a lower movement speed.

Radio link monitoring and cell search techniques for high movement speeds

A method of data transmission includes establishing a buffer for TCP/IP data packets, receiving and buffering the TCP/IP data packets including TCP payloads and TCP ACKs. A queue of the buffered TCP/IP data is adjusted in accordance with header information of the TCP/IP data packets. The buffered TCP/IP data packets are transmitted sequentially. The method significantly reduces the TCP ACKs, which are transmitted with priority, thereby reducing the round-trip time delay, and improving the data transmission efficiency. An apparatus configured to perform this method is also described.

The present invention provides a power-saving method for a mobile terminal, comprising the steps, after setting the mobile terminal to be in a data service power-saving state, monitoring, by the mobile terminal, a data service in accordance with a monitoring strategy for the data service power-saving state, and triggering a data service power-saving operation when a triggering condition set in the monitoring strategy is met. The present invention further provides a power-saving apparatus arranged within a mobile terminal, comprising a monitoring unit and an executing unit, wherein the monitoring unit is configured to monitor data services of the mobile terminal in accordance with a preset monitoring strategy, and send a power-saving command to the executing unit when a data service power-saving strategy is met. The present invention further provides a mobile terminal comprising the power-saving apparatus. As a result, the mobile can rapidly enter the data service power-saving mode according to the monitoring strategy, reduce unnecessary power consumption, and prolong the service time for the mobile terminal.
