Problems solved by technology

[0004] However, the inventor found in the research that the prior art queue management method of "discarding service data when the buffer queue is full" is to discard service data after the buffer queue becomes full, but in fact, usually when the buffer queue becomes full Before the network is full, the network has already been congested. When the network is congested, the data transmitted through the network will have a large transmission delay, which cannot meet the needs of low-latency services.

Embodiment Construction

[0016] Embodiments of the present invention provide a data processing method, device, and system. When sending service data, calculate the transmission delay of the data to be sent to the receiving end; when the transmission delay is less than the minimum delay threshold, the buffer waiting For sent data, when the transmission delay is greater than the maximum delay threshold, the data to be sent is discarded; when the transmission delay is between the minimum delay threshold and the maximum delay threshold, the probabilistic packet loss method is used to process the pending data sent data.

[0017] Through the above method, the transmission delay of service data can be reduced, the requirement of low-latency service can be met, and network resources can be saved.

[0018] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Taking the service data transmission of the CDMA2000 1xEVDO Rev.A network syste...

Abstract

The embodiment of the invention discloses a data transmit method, which comprises calculating transmission delay when data waiting to be transmitted is transmitted to a receiving terminal; and when the transmission delay is smaller than minimum delay threshold, transmitting the data waiting to be transmitted, when the transmission delay is larger than maximum delay threshold, discarding the data waiting to be transmitted, and when the transmission delay is between the minimum delay threshold and the maximum delay threshold, treating the data waiting to be transmitted by adopting a probability packet loss method. Accordingly, the embodiment of the invention also discloses a data treatment device and a communication system, which can effectively reduce the transmission delay of business data and satisfy the business requirement of low delay.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a data processing method, device and communication system. Background technique [0002] Now, as more and more low-latency services are applied in wireless communication networks, higher requirements are placed on the transmission delay of wireless communication networks, and it is hoped to further reduce the transmission delay of business data in wireless networks . The transmission delay of service data in the wireless communication network is generally divided into two parts, one part is the transmission delay on the air interface, and the other is the transmission delay on the network device. The transmission delay on the air interface refers to the delay caused by the transmission of service data on the data transmission channel, while the transmission delay on the network device is mainly caused by the service data waiting to be processed in the buff...
