Problems solved by technology

Unable to meet the needs of low-latency services
[0006] In order to reduce the transmission delay of the PON network, a fixed bandwidth allocation mechanism can be used to allocate fixed time slots to different service signals, and at the same time reduce the time slot interval between services and the length of the allocated time slot bandwidth to reduce transmission delay. To meet some low-latency data transmission requirements, but because this method requires a fixed service bandwidth, the flexibility of service transmission may be reduced; and when the service bandwidth is less than the fixed bandwidth allocated by the system, there will be idle time slots, Limited bandwidth resources are wasted, so this method has poor bandwidth utilization
It is also possible to reduce the delay by optimizing the DBA algorithm, increase the priority of low-latency service signals, and realize fast forwarding, but this method of reducing delay

Abstract

The invention provides a data transmission method and apparatus. The method comprises the following steps: obtaining a first type of data and a second type of data to be sent, wherein a transmission delay allowed by the first type of data is smaller than the transmission delay allowed by the second type of data; and sending first type of data that needs to be transmitted instantaneously on a firstcarrier frequency band of a transmission channel between a target optical line unit and an optical line unit, wherein the transmission channel allows the simultaneous transmission of the first type of data and the second type of data, and the lowest frequency in the second frequency band for sending the second type of data on the transmission channel is higher than the highest frequency in the first carrier frequency band. By adoption of the data transmission method and apparatus, the technical problem of high cost of transmitting data with different delays in a passive optical network is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method and device. Background technique [0002] With the development of the Internet, IoT applications such as Internet of Vehicles, smart medical care, and smart home have been widely used. Mobile communication is not limited to communication between people, but is also moving towards communication between people and things and between things. Internet will become an inevitable trend. At present, the cellular-based narrowband Internet of Things NB-IOT (Narrow Band Internet of Things, NB-IOT) has become an important branch of the Internet of Everything. As an evolution technology of LTE, 4.5G wireless network not only has a peak rate of up to 1Gbps, but also means more connections based on cellular IoT, supports massive M2M (Machine to Machine) connections and ultra-low latency. Passive Optical Network (PON, referred to as Passive Optical Network) has the...
