Abstract

The embodiment of the present invention discloses a network slice registration method and device based on non-standard S-NSSAI in a roaming scene, relates to the field of communication technology, and is used to solve the problem of network slice registration when a roaming UE uses a non-standard S-NSSAI to register network slices in the prior art The technical problem of low access efficiency. In the embodiment of the present invention, by presetting the mapping relationship between the S-NSSAI of the user's home PLMN and the S-NSSAI of the local PLMN in the access and mobility management function AMF, the roaming UE can effectively simplify the use of non-standard S-NSSAI to register network slices The S-NSSAI mapping process between PLMNs improves the access efficiency of network slices when roaming UEs use non-standard S-NSSAIs to register network slices. The embodiment of the present invention is used for a roaming UE to use a non-standard S-NSSAI network slice registration process.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a non-standard S-NSSAI-based network slice registration method and device in a roaming scenario. Background technique [0002] Currently, network slice access is identified through network slice selection assistance information (network slice selection assistance information, NSSAI). Each NSSAI contains a plurality of network slice selection assistance information (single network slice selection assistance information, S-NSSAI), which can be regarded as a collection of S-NSSAI. S-NSSAI can be a standard value or a non-standard value, and each S-NSSAI corresponds to a specific network slice instance. [0003] When performing network slice registration, if the user equipment (UE) uses a non-standard S-NSSAI in the roaming scenario, according to the requirements of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GP...
