Embodiment Construction

[0048] Embodiments of the present invention provide a hierarchical slice-based 5G service bearing method, which is used to implement end-to-end service transmission in a RAN network, a TN network, and a CN network, including the following steps:

[0049] Set the flow label carried by the service flow, and the flow label includes FlowID, NSSID and service type;

[0050] When a new slice is created in the RAN network or TN network, the SDN delivers the NSSID of the slice and the SLA parameters corresponding to the service type to the other two networks, and the ingress PEs of the other two networks receive the NSSID of the slice delivered by the SDN controller. When adding and matching SLA parameters, search whether there are slices that meet the SLA parameter requirements in the network. If so, add the corresponding relationship between the slices in the three networks to the local slice service mapping table. If not, create a configuration that meets the SLA parameter requireme...

Abstract

The invention discloses a hierarchical slice-based 5G service bearing method and system, and relates to the technical field of 5G packet transmission network. The invention adopts a globally unique flow label to carry FlowID, service type and slice information, and through these carried The information realizes the matching of slices in the RAN, TN and CN three-segment networks, realizes efficient cross-slice transmission of services, and effectively solves the end-to-end slice problem. During slice matching, the matching content can be effectively distinguished for different types of services, the matching depth is small, the matching domain is also reduced, and the matching efficiency can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of 5G packet transmission network, in particular to a hierarchical slice-based 5G service bearing method and system. Background technique [0002] End-to-end service delivery based on slices is a basic requirement of 5G networks. However, the processing of services needs to go through three sections of network, radio network RAN ​​(Radio Access Network) + bearer network TN (Trunk network) + core network CN (Core Network), such as figure 1 shown. The slices in each segment of the network are independent of each other. When the packet service enters from one segment of the network to another segment of the network, it does not carry slice information. Therefore, how to use slices to achieve end-to-end business processing is a challenge. The main problems are: [0003] (1) For the services carried by slices in the wireless network RAN, the slice information is lost after leaving the RAN, and the cor...
