Abstract

The embodiment of the invention discloses a data transmission method and device, a system, a terminal and an access network device and belongs to the technical field of communication. According to theembodiment of the invention, an SR (Scheduling Request) resource and an uplink transmission resource corresponding to the SR resource are pre-allocated to the terminal; when the terminal has uplink data of appointed business needing to be transmitted, the terminal can send an SR through adoption of the SR resource; the SR indicates that the terminal has the uplink data of the appointed business needing to be transmitted to the access network device; and the terminal sends the uplink data of the appointed business through adoption of an uplink transmission resource corresponding to the SR resource. The time for the terminal to acquire the uplink transmission resource for transmitting the uplink data can be clearly reduced, so the data transmission delay of the uplink data of the appointedbusiness can be reduced.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a data transmission method, device, system, terminal and access network equipment. Background technique [0002] With the continuous development of communication technology, there are more and more types of communication services, and different types of communication services have different requirements for data transmission delay. Among them, the data transmission delay refers to the time it takes for one of the two parties to send business data to the other party, which is mainly caused by the data processing time of the communication device and the communication device waiting for available data transmission resources The time required and the time used to transmit data using data transmission resources are composed of. [0003] In the current Long Term Evolution (English: Long Term Evolution, abbreviated as: LTE) system, both uplink transmission resources and dow...
