Embodiment 1

[0037] Such as figure 2 As shown, it is a schematic diagram of the implementation flow of the network side data transmission method provided by the embodiment of the present invention, including the following steps:

[0038] S201. The base station receives a data transmission request sent by the MTC terminal in an idle state;

[0039] Specifically, when the MTC terminal is in an idle state, it requests the base station to perform data transmission.

[0040] S202. The base station obtains the service type of the service used by the MTC terminal;

[0041] Specifically, the base station can obtain the service type of the service used by the MTC terminal in the following two ways: 1) The data transmission request sent by the MTC terminal to the base station carries the terminal identifier, and the base station receives the data transmission request sent by the MTC terminal. , according to the terminal identification of the MTC terminal, the service type of the service used by t...

Embodiment 2

[0061] Based on the same inventive concept, Embodiment 2 provides a data transmission device. Since the problem-solving principle of the device is similar to that of the data transmission method, the implementation of the device can refer to the implementation of the method, and repeated descriptions will not be repeated.

[0062] Such as image 3 As shown, it is a schematic structural diagram of a data transmission device provided by an embodiment of the present invention, including:

[0063] The receiving unit 301 is configured to receive a data transmission request sent by the MTC terminal in an idle state;

[0064] An obtaining unit 302, configured to obtain the service type of the service used by the MTC terminal;

[0065] A selection unit 303, configured to select a data retransmission mode according to the service type obtained by the obtaining unit 302;

[0066] The transmission unit 304 is configured to retransmit the transmitted downlink data according to the selec...

Embodiment 3

[0081] Embodiment 3 provides a terminal-side data transmission method. This method is based on the same inventive concept as Embodiment 1. Since the problem-solving principle of this method is similar to that of the data transmission method in Embodiment 1, the implementation of this method can refer to the implementation of the method. Repeated points will not be repeated.

[0082] Such as Figure 4 As shown, it is a schematic diagram of the implementation process of the data transmission method on the terminal side, which may include the following steps:

[0083] S401. When the MTC terminal is in an idle state, send a data transmission request to the network side;

[0084] S402. The MTC terminal receives the feedback message sent by the network side;

[0085] S403. The MTC terminal retransmits the transmitted uplink data according to the received feedback message.

[0086] Wherein, the feedback message received by the MTC terminal may carry the number of data retransmissi...

Abstract

The invention discloses a data transmission method, device, system and related equipment to ensure the reliability of data transmission in an idle state. The data transmission method includes: receiving a data transmission request sent by an MTC terminal in an idle state; Obtaining the service type of the service used by the MTC terminal; selecting a data retransmission mode according to the service type; and retransmitting the transmitted downlink data according to the selected data retransmission mode.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a data transmission method, device, system and related equipment. Background technique [0002] Machine-Type Communication (MTC, Machine-Type Communication) refers to the communication between machines or devices (M2M, Machine to Machine) without human participation. Such as figure 1 As shown, it is a schematic diagram of the MTC terminal communication scene in the prior art. Each MTC terminal communicates with the MTC server through the operator network, and each MTC terminal can send uplink data to the MTC server, and can also receive downlink data sent by the MTC server. Data is transmitted between the MTC terminal and the MTC server through the base station. [0003] With the rapid development of M2M services, the scale of MTC terminals will grow exponentially, and the number of MTC terminals in the same cell may reach tens of thousands. The core net...
