Problems solved by technology

However, in existing technical standards and implementation methods, when the network side instructs the terminal to enter the uplink DTX state, the uplink physical channel control message carries the entry into the uplink DTX state to indicate the default uplink DTX state, that is, the default uplink DTX state is on, and always remains It is effective, but there is no method or process to instruct the terminal to turn off the uplink DTX state, which means that the uplink DTX state of the terminal cannot be controlled between on and off

Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0044] Because in the existing technical standards and implementation methods, when the network side instructs the terminal to enter the uplink DTX state, there is no method or process to instruct the terminal to turn off the uplink DTX state, so that the uplink DTX state of the terminal cannot be controlled between on and off. A terminal entering the uplink DTX state will prevent the network side from obtaining the uplink radio frequency signal sent by the terminal within the period of the network side's synchronization and power control mechanism for the terminal, resulting in out-of-synchronization or disconnection of the wireless link between the terminal and the network side and other abnormal phenomena.

[0045] In order to overcome this problem, ...

Abstract

Disclosed are a method, system and device for controlling an uplink discontinuous transmission (DTX) state. When a network side wishes to turn off an uplink DTX state in which a terminal is located, the network side sends to the terminal an uplink physical channel control message not carrying a special burst time sequence arrangement indication, and instructs the terminal to turn off the uplink DTX state, turn on its own radio frequency transmitter, and recover so as to transmit continuously transmitted radio frequency signals.Thus, the method, system and device provided by the present invention can turn off the uplink DTX state of a terminal.

Description

technical field [0001] The present invention relates to the control technology of the radio frequency signal in the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, in particular to a control method for the uplink discontinuous transmission (DTX, Discontinuous transmission) state in the TD-SCDMA system, systems and devices. Background technique [0002] In the TD-SCDMA system, the transmission of DTX radio frequency signals between the terminal and the network side is a standard technology and function defined by the 3GPP international standard. When a wireless link is established between the terminal and the network side in the TD-SCDMA system, if there is no communication interaction between the terminal and the network side temporarily, that is, there is no transmission data block provided by the terminal or the network side for any given coded composite transmission When the channel (CCTrCH) is used to transmit radio frequency signals, the term...
