Problems solved by technology

That is, when using the HSDPA multi-flow technology that distributes traffic between NodeBs, the NodeB cannot currently control the activation or deactivation of the DTX / DRX function
When the UE activates DTX, if the NodeB detects that the uplink pilot is degraded and the wireless link is out of sync, if the DTX is not activated in time, a large number of data services will be retransmitted and even the UE may drop calls.
[0007] Aiming at the problem that the NodeB cannot control the activation or deactivation of the DTX / DRX function when the traffic is distributed between NodeBs in the related technology, no effective solution has been proposed so far.

Embodiment 1

[0036] An embodiment of the present invention provides a flow chart of a DTX / DRX activation method, figure 2 It is the flow of the DTX / DRX activation method according to the embodiment of the present invention Figure 1 ,like figure 2 As shown, the process includes the following steps:

[0037] Step S202, the radio network controller RNC receives a notification from the base station NodeB that DTX / DRX needs to be activated or deactivated;

[0038] Step S204, according to the notification, the RNC instructs the NodeB and / or other NodeBs offloaded with the NodeB to activate or deactivate DTX / DRX.

[0039] Through the above steps, the problem that the NodeB cannot currently control the activation or deactivation of the DTX / DRX function during traffic distribution between NodeBs is solved, and has the beneficial effect of cooperating with other NodeBs to activate or deactivate.

[0040] There are many ways for NodeB to notify RNC that it needs to activate or deactivate DTX / DR...

Embodiment 2

[0045] An embodiment of the present invention provides a discontinuous transmission / discontinuous reception DTX / DRX activation method, image 3 It is the flow of the DTX / DRX activation method according to the embodiment of the present invention Figure II ,like image 3 As shown, the process steps in the following steps:

[0046] Step S302, the NodeB sends a notification to the radio network controller RNC that DTX / DRX needs to be activated or deactivated;

[0047] In step S304, the NodeB and / or other NodeBs that are offloaded with the NodeB receive an indication from the RNC to respond to the notification and activate or deactivate DTX / DRX according to the indication.

[0048] Preferably, NodeB determines that DTX / DRX needs to be activated or deactivated, and sends a radio link parameter update message to RNC to inform RNC that DTX / DRX needs to be activated or deactivated.

[0049] Preferably, the NodeB and / or other NodeBs that are offloaded with the NodeB receive the radi...

Embodiment 3

[0051] An embodiment of the present invention provides a structural block diagram of a device for activating DTX / DRX. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and those that have already been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0052] Figure 4 is the structural frame of the DTX / DRX activation device according to the embodiment of the present invention Figure 1 ,like Figure 4 As shown, the device includes a receiving module 402 and an indicating module 404 .

[0053] The receiving module 402 is configured to receive a notification sent by the base station NodeB that DTX / DRX needs to be activat...

Abstract

Disclosed is a method and device for activating discontinuous transmission / discontinuous reception DTX / DRX. the method comprises: a radio network controller (RNC) receives information of needing to activate or deactivate DTX / DRX sent by a base station (NodeB); the RNC indicates that the NodeB and / or any other NodeB shunting with said NodeB needs to activate or deactivate DTX / DRX according to the information. The present invention solves the problem that the NodeB can not control to activate or deactivate the DTX / DRX function when shunting between NodeBs, and achieves the beneficial effect of activating or deactivating in collaboration with other NodeB.

Description

technical field [0001] The present invention relates to the communication field, in particular to a discontinuous transmission / discontinuous reception DTX / DRX activation method and device. Background technique [0002] With the continuous and rapid development of data services, High Speed ​​Downlink Packet Access (HSPA for short) technology is becoming more and more common, and it is developing towards the direction of multi-antenna and multi-carrier. For example, the R7 version of 3GPP introduced multiple input multiple output (MIMO for short) technology, so that NodeB (base station) can send two The technology of discontinuous transmission / discontinuous reception (DTX for short) was introduced to improve the capacity of the network; subsequently, the R8 version of 3GPP introduced the dual-carrier high-speed downlink packet access (Double Carrier High Speed Downlink Packet Access (DC-HSDPA for short) technology enables NodeB to send HSDPA data to UE from two frequency poin...
