Network slice management method and device

Abstract

The invention discloses a network slice management method and device, which are used for optimizing the management of end-to-end network slices. The method comprises the following steps: a proxy nodereceiving a network slice creation request from the NSMF, wherein the network slice creation request is used for requesting to create a first end-to-end network slice sharing resources with the created end-to-end network slice; wherein the first end-to-end network slice comprises a first core network slice and a first access network slice; creating a first core network slice according to the network slice creation request, wherein the first core network slice and the created second core network slice share resources; and sending an access network slice creation request to an access network device supporting the network slice agent, the access network slice creation request being used for requesting creation of a first access network slice, the access network slice creation request carryingfirst indication information, and the first indication information being used for indicating that the first core network slice and the second core network slice share resources.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a network slice management method and device. Background technique [0002] The fifth generation (the 5th-generation, 5G) mobile communication system introduces network slicing technology to cope with the differences in network performance requirements of different communication services. In related technologies, the slicing that can be implemented to provide end-to-end network services from an access network (access network, AN) to a core network (core network, CN) for a terminal is called end-to-end network slicing. Hereinafter, AN and CN are collectively referred to as a subnet. The end-to-end network slicing may include subnet slicing, such as core network slicing, access network slicing, and the like. [0003] In the prior art, an end-to-end network slice is managed through a network slice management function (network slice management function, NSMF)...

AI Technical Summary

Problems solved by technology

[0004] The early research on network slicing mainly focused on the core network, and the research on access network slicing is relatively scarce. The deployment of NSSMF in the AN is late, and there may be scenarios where NSSMF is not deployed in the AN. In this scenario, NSMF cannot be connected. Incoming network slices are managed, and end-to-end network slice management cannot be realized

[0005] In addition, even if NSSMF has been deployed in the AN, since NSMF does not understand the implementation details of the control plane of each subnet, it may lead to inconsistent decisions made by NSSMF in each subnet when managing subnet slices
