Embodiment 1

[0072] In the method for controlling the uplink discontinuous transmission state provided by Embodiment 1 of the present invention, when the default uplink DTX switch state of the UE is on and the default SBGP value configured on the network side is used, the uplink DTX switch of the UE after entering the current cell State control process, such as Figure 5 As shown, it specifically includes the following steps:

[0073] Step S40: start.

[0074] In the initial state, the UE is in the state where the uplink DTX state is enabled, and transmits uplink data with the SBGP value configured on the network side.

[0075] Step S41: The network side judges whether the current cell supports enabling the uplink DTX state. When the judgment is yes, execute step S44; when the judgment is no, execute step S42.

[0076] Step S42: The network side configures the uplink data transmission format as the uplink DTX off state, and sends an execution message carrying the uplink data transmissio...

Embodiment 2

[0087] In the method for controlling the uplink discontinuous transmission state provided by Embodiment 2 of the present invention, when the default uplink DTX switch state of the UE is off, then, when the UE enters the current cell, the uplink DTX switch state control process is as follows: Figure 6 As shown, the following steps are performed:

[0088] Step S50: start.

[0089]In the initial state, the UE is in the state of uplink DTX off and transmits continuous data, but the UE still has the SBGP value configured by the network side or 3GPP protocol.

[0090] Step S51: The network side judges whether the current cell supports enabling the uplink DTX state. When the judgment is yes, execute step S52; when the judgment is no, execute step S56.

[0091] If the current cell does not support the uplink DTX on state, then the UE maintains the initial uplink DTX off state, and sends the uplink data including the parity bit but not the RLC layer PDU data, so it directly turns to...

Abstract

The invention discloses a control method, a control device and a communication system of an uplink discontinuous transmission state. The method comprises the following steps that: a network side configures a transformat of uplink data for user equipment (UE), wherein the transformat is used as an uplink discontinuous transmission (DTX) state conversion instruction; an execution message carrying the uplink DTX state conversion instruction is transmitted to the UE; and the UE is indicated to convert the on-off state of the uplink DTX according to the uplink DTX state conversion instruction in the received execution message. With the adoption of the method, the on-off state of the uplink DTX of the UE can be converted, so that the network can control the conversion of the on-off state of the uplink DTX of the UE according to practical demands conveniently.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method, device and communication system for controlling an uplink discontinuous transmission state. Background technique [0002] Discontinuous transmission (DTX) is a standard technology defined in the 3rd Generation Partnership Project (3GPP) international standard and the China Communications Standards Association (CCSA) industry standard. [0003] In the mobile communication system of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), under normal circumstances, after the wireless link is established, the upper layer will continuously send transmission blocks to the The Coded Composite Transport Channel (CCTrCH) is transmitted in the way of service combination and physical resource allocation; when no transport block is provided by the upper layer for any CCTrCH for transmission, it enters the DTX state. According to different link transmission directi...
