Embodiment Construction

[0040] In order to make the content of the present invention more comprehensible, the following specific embodiments are taken as examples in which the present invention can be implemented. In addition, wherever possible, elements / members / steps with the same reference numerals are used in the drawings and embodiments to represent the same or similar parts.

[0041]In 3GPP TS 23.501 and / or 3GPP TS 23.502, a network slice includes required network function instances (required network functions instances, required NFI) and related resources. A user device may request a network slice from the 5G core network during the registration procedure. Then, the user equipment can request network slices from the 5G core network through a request message including network slice selection assistance information (network slice selection assistance information, NSSAI), where the NSSAI can include up to 8 S-NSSAI, and each S-NSSAI NSSAI corresponds to a network slice in a one-to-one manner. In...

Abstract

A method for accessing a network slice and user equipment using the same are provided. The method for accessing a network slice includes: transmitting a request message to a 5G communication network;receiving, from the 5G communication network, allowed network slice selection assistance information in response to the request message; obtaining mutually exclusive network slices information according to the allowed network slice selection assistance information; and establishing multiple sessions respectively corresponding to multiple network slices according to the mutually exclusive network slices information.

Description

technical field [0001] The present disclosure relates to a method for accessing network slices and a user device using the method. Background technique [0002] The fifth generation (fifth generation, 5G) communication network supports network slicing (network slicing) technology to provide different network services for user equipment (UE). A network slice (ie, a network slice instance (NSI)) is a logical network that provides specific network capabilities (network capability) and network characteristics (network characteristics). The network slice can be configured to have control plane (CP) functions and user plane (UP) functions. The user equipment can simultaneously access multiple network slices in the 5G communication network through the next generation radio access network (NG-RAN), so as to use various network slices respectively provided by the multiple network slices. Serve. However, some network slices cannot be accessed at the same time depending on the conte...
