Problems solved by technology

[0006] In the prior art, because the specific situation of each UE is usually not considered, all UEs in a certain coverage area are allocated the same fixed DTX cycle, and even all UEs in the network are uniformly allocated a fixed DTX cycle. Therefore, some UEs affect the link quality because the allocated DTX period is greater than the period it actually needs, while some UEs have a relatively small DTX period, which causes unnecessary interference to other UEs by sending special bursts too frequently

Embodiment Construction

[0065] 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 in conjunction with the embodiments and accompanying drawings.

[0066] figure 1 It is an exemplary flow chart of the DTX control method in the embodiment of the present invention. Such as figure 1 As shown, the process includes the following steps:

[0067] Step 101 , acquiring communication status information of a UE in a current DTX cycle.

[0068] In this step, the communication status information of the UE can be expressed as the link quality information of the UE, or the moving speed information of the UE, or other information, etc. Correspondingly, there are many methods for the network side to obtain the communication status information of the UE kind. Taking the TD-SCDMA system as an example, several implementation methods are listed below to describe this step in detail.

[0069] The first method:...

Abstract

The invention discloses a control method of discontinuous transmission (DTX), and the control method comprises the following steps: the communication condition information of user equipment (UE) in a current DTX period is obtained;, a target DTX period which meets the link quality of the UE is determined according to the communication condition information; and the target DTX period is taken as the current DTX period for the discontinuous transmission. In addition, the invention further discloses a discontinuous transmission (DTX) control system and a wireless network control unit. The technical proposal of the invention can minimize the interference on other users under the premise of ensuring the link quality of the UE.

Description

technical field [0001] The present invention relates to communication technology, in particular to a discontinuous transmission (DTX) control method, system and wireless network control unit. Background technique [0002] In the communication system, some specific services, such as voice services and videophone services, work in a half-duplex mode, that is, when one party speaks, the other party is only answering, and it is reflected in one direction in transmission. (such as upstream) while sending data, in the other direction (such as downstream) there is no actual information to be transmitted, but only background noise. In this case, the link transmission in the direction where there is no actual information to be transmitted can be temporarily interrupted, and the link transmission can be resumed when there is actual information to be transmitted, which is usually called a discontinuous transmission (DTX) technology. Applying this technology to the uplink is uplink DTX...
