Embodiment 1

[0031] Embodiments of the present invention provide a data transmission method, such as figure 2 Shown include:

[0032] S101. The transport network controller acquires slice information of service data transmitted by the transport network; wherein, the source address of the service data is the address of the first user equipment, and the destination address of the service data is the address of the second user equipment.

[0033] It should be noted that, in practical applications, such as image 3When the shown UE1 (first user equipment) and UE2 (second user equipment) perform uRLLC low-latency service communication, the specific service establishment process is as follows:

[0034] 1. When the uRLLC service is established, UE1 will first report the slice information (including the slice type uRLLC slice and the slice ID slice ID) to the radio network controller through the eNodeB, and the radio network controller reports it to the network orchestrator.

[0035] Specifical...

Abstract

The embodiments of the present invention provide a data transmission method and a transport network controller, which relate to the technical field of communication, and solve the problem of how to ensure the service quality of low-latency services. The method includes that: the transport network controller acquires slice information of the service data transmitted by the transport network, wherein a source address of the service data is an address of the first user equipment, and a destination address of the service data is an address of the second user equipment; the transport network controller determines whether a sending link and a receiving link of the service data corresponding to the target slice information in the service data pass through the same transmission node in an access ring of the transmission network, wherein the sending link is a path through which the first user equipment transmits the service data to a core network, and the receiving link is a path through whichthe second user equipment can receive the service data from the core network; and the transmission network is controlled to forward the service data received from the first user equipment to the second user equipment via the transmitting node.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data transmission method and a transmission network controller. Background technique [0002] In recent years, people have paid more and more attention to network delay performance, and gradually become a new hot spot in the communication industry. The low-latency network has also become the development direction that operators are concerned about. With the in-depth development of "Internet +", the telecommunications network has begun to be deeply integrated with all walks of life. Some emerging industries and emerging services have put forward almost stringent requirements for network delay, and some requirements have even reached the existing optical transport network technology and The extent to which the networking structure cannot meet the requirements. Therefore, it is very necessary to conduct an in-depth analysis of the low-latency service requirements, so as t...
