Problems solved by technology

[0004] However, the applicant found through research that in order to save the power consumption of the UE, the DRX cycle of the UE is relatively short, which means that when the MAC needs to schedule the UE, the probability of the UE being in a silent period is relatively high, but the existing NBIoT system Continuing the processing scheme of the original LTE (Long Term Evolution, long-term evolution) system, resulting in the MAC needing to consume a large amount of processing resources and processing time for judging when the MAC judges whether multiple timers have timed out in sequence
That is, the current data transmission method has the problem of consuming MAC processing resources and processing time

Embodiment 1

[0079] figure 1 It shows a flow chart of the steps of a method for transmitting data based on a base station in Embodiment 1 of the present application, the base station includes a radio link layer control device RLC and a media access control device MAC, and the method is applied to the RLC, The method may specifically include the following steps:

[0080] Step 101, determine data to be sent.

[0081] It should be noted that the base station may include multiple protocol layers for data interaction, which are respectively from top to bottom: PDCP (Packet Data Channel, packet data channel), RLC (Radio Link Control, radio link layer control), MAC And PHY (Physical, physical layer). Data is usually passed sequentially from PDCP to PHY.

[0082] In a specific implementation, the RLC may receive some data that needs to be sent to the user terminal from the PDCP of the upper layer, and may determine the data as the data to be sent. The user terminal can be a terminal based on t...

Embodiment 2

[0097] figure 2 It shows a flow chart of the steps of a method for transmitting data based on a base station in Embodiment 2 of the present application, the base station includes a radio link layer control device RLC and a media access control device MAC, and the method is applied to the RLC, The method may specifically include the following steps:

[0098] Step 201, receiving the activation configuration message list of each user terminal sent by the MAC.

[0099] Step 202, saving the activation configuration message table of each user terminal locally.

[0100] In a specific implementation, the RLC may receive the activation configuration message table of each user terminal from the MAC, and store the activation configuration message table locally as a preset activation configuration message table, so as to search for the target activation configuration message subsequently.

[0101] Step 203, determine the data to be sent.

[0102] Step 204, in the preset activation con...

Embodiment 3

[0129] image 3 It shows a flow chart of the steps of a base station-based data transmission method according to Embodiment 3 of the present application. The base station includes a radio link layer control device RLC and a media access control device MAC, and the method is applied to the MAC. The method may specifically include the following steps:

[0130] Step 301, receiving the data to be sent sent by the RLC when the current sending time matches the activation time period; wherein, the activation time period is after the RLC determines the data to be sent, in the preset time period of each user terminal Find in the activation configuration message table, the target user terminal pointed to by the data to be sent and the corresponding target activation configuration message, and the activation time period of the target user terminal activation data reception state determined according to the target activation configuration message;

[0131] Step 302, delivering the data to ...

Abstract

The embodiment of the present invention provides a data transmitting method, device and system, and the method includes the steps: determining to-be-transmitted data; searching a target user terminalpointed by the to-be-transmitted data and a corresponding target activation configuration message from a preset activation configuration message table of all user terminals, wherein the target activation configuration message includes an activation time period in which the target user terminal activates a data reception state; reading the current time; transmitting to-be-transmitted data to an MACwhen the current time is matched with the activation time period, wherein the MAC is used to transmit the to-be-transmitted to a target user terminal in a data receiving state. According to the embodiment of the present invention, the method can save processing resources and processing time of the MAC.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a base station-based data sending method, a base station-based data sending device, and a data sending system. Background technique [0002] Currently, a UE (User Equipment, user terminal) usually communicates with a base station with a DRX function (Discontinuous Reception, discontinuous reception) based on an NBIoT (Narrow Band Internet of Things, cellular-based narrowband Internet of Things) system. According to the provisions of the 3GPP 36.321 protocol for the NBIoT system, the RRC (Radio Resource Control, radio resource control) of the base station can configure a DRX cycle for the UE, and the UE determines its own activation time period according to the DRX cycle. When the UE is in the active period, it communicates with the base station by monitoring the PDCCH (Physical Downlink Control Channel) of the base station to receive the NBIoT data delivered...
