Problems solved by technology

[0007] At present, traditional transport network technology is used to create services in the communication network. The transport network is only used as a transmission pipeline between the base station and the mobile core network. The network capacity of the transport network can only be planned in advance according to the bandwidth requirements of the wireless access service. It is impossible to tailor the corresponding service path for the service according to the specific service characteristics, that is, the network slicing situation corresponding to the service
As a result, the transmission efficiency of the transport network is low, and the quality of service transmission cannot be guaranteed.

Embodiment Construction

[0028] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0029] The embodiments of the present application are applied in a communication network. The embodiment of the present application provides a communication network architecture, specifically as follows figure 1 Said, the communication network includes user equipment UE, base station equipment, transport network, transport network controller, core network, core network controller and network orchestrator. The UE is connected to the core network through a base station and a transport network. The core network is divided into two network slices, slice1 and slice2 in the figure, which provide services for eMBB (Enhance Mobile Broadband, enhanced mobile broadband) business and uRLLC (Ultra Reliable & Low Latency Communication, low latency, high reliability communication) business respectively. . The two network slices share a transport network network. The n...

Abstract

The invention discloses a transmission network service establishment method and equipment, and relates to the field of the communication. Through the transmission network service establishment methoddisclosed by the embodiment of the application, a transmission path suitable for the target service is provided for the target service in the transmission network according to different slice types ofthe target service. The method comprises the following steps: a network composer acquires slice information of the target service; the network composer determines a transmission parameter of the target service according to the slice information, and sends the transmission parameter of the target service to a transmission network controller; the transmission network controller determines the transmission path according to the transmission parameter, and a source address, a host address and a bandwidth requirement of the target service, and sends the transmission path to the transmission network equipment. The establishment method disclosed by the application is applied to the communication network.

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a method and device for establishing a transport network service. Background technique [0002] Diversified service scenarios put forward diverse performance and functional requirements for mobile communication networks. Therefore, the mobile core network is also required to have the ability to adapt to service scenarios, and to provide appropriate network control functions and performance guarantees for each service scenario. , to achieve the goal of on-demand networking. In order to realize on-demand networking, the fifth generation mobile communication technology (5G) proposes the concept of network slicing. [0003] Network slicing is to use virtualization technology to virtualize network physical infrastructure resources into multiple independent parallel virtual network slices according to scenario requirements. Each network slice customizes and tailors networ...
