AI Technical Summary

Problems solved by technology

When the service requested by the slice request needs to implement a specific isolation capability, the coordinator cannot select a path that supports a specific isolation capability from the path of A-B-C-E-G-H and the path of A-B-D-F-G-H
This will result in the inability to allocate corresponding network resources to the business corresponding to the slice request, so as to achieve the isolation capability required by the business

Embodiment 1

[0084] figure 2 It is a schematic diagram of a network scenario provided in Embodiment 1 of this application. exist figure 2 In the scenario shown, domain A includes multiple nodes, such as figure 2 R1 and R3 in. R1 and R3 may be edge nodes in domain A. Domain B includes at least one node such as figure 2 R2 in. R2 may be an edge node in domain B. Domain A may be a wireless network, a bearer network or a core network. Domain B may be a wireless network, a bearer network or a core network. Domain A and domain B can be subnets in the same network, or domain A and domain B can be different networks respectively. The control device can communicate with the nodes in domain A and domain B, and configure the nodes in domain A and domain B. R1 and R2 can communicate through multiple paths, such as figure 2 P1 and P2 in. P1 and P2 are used to identify different paths. Wherein, the path identified by P1 may be expressed as R1-R2. The path identified by P2 can be expres...

Embodiment 2

[0125] Figure 5 It is a schematic diagram of a network scenario provided in Embodiment 2 of this application. exist Figure 5 In the scenario shown, domain A includes multiple nodes, such as Figure 5 R1 and R3 in. R1 and R3 may be edge nodes in domain A. Domain B includes at least one node such as Figure 5 R2 in. R2 may be an edge node in domain B. The types of domain A and domain B may be the same as those in Embodiment 1, and will not be repeated here. The control device can configure the nodes in Domain A and Domain B. Specifically, the first domain controller included in the control device may communicate with the nodes in domain A to configure the nodes in domain A. The second domain controller included in the control device can communicate with the nodes in domain B to configure the nodes in domain B. The control device includes a coordinator capable of communicating with the first domain controller and the second domain controller. In an implementation mann...

Abstract

The invention discloses a method for obtaining a network slice, and the method comprises the steps that control equipment receives a slice request sent by a user, the slice request comprises an recognition, and the recognition is used for identifying the isolation level of a slice requested by the user; the control equipment acquires the isolation type of the slice according to the identifier; andthe control equipment performs control according to the isolation type and the resource topology of the slice , wherein the resource topology is used for describing the network topology and the isolation capability of N elements in the network topology, the N elements comprise at least one of a node and a link, the N is an integer greater than or equal to 1, and the network slice comprises a nodeand a link required for realizing the slice.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method, device and system for acquiring network slices. Background technique [0002] figure 1 Schematic diagram of a network scenario for obtaining network slices. exist figure 1 In the shown scenario, the control device includes an orchestrator (orchestrator), a controller (controller) of network (network) A, and a controller of network B. The controller 1 of the network A obtains the topology information of the network A by communicating with the nodes included in the network A. Network A includes Node A, Node B, Node C, and Node D. Controller 1 sends the acquired topology information of network A to the coordinator. The controller 2 of the network B obtains the topology information of the network B by communicating with the nodes included in the network B. Network B includes Node E, Node F, Node G, and Node H. The controller 2 sends the acquired topology infor...
