Title:
スライスベース通信方法およびデバイス
Document Type and Number:
Japanese Patent JP7035078
Kind Code:
B2
Abstract:
A slice-based communications method and device are disclosed. The method includes: sending, by an AMF node, a first request message to an NSSF node; and receiving, by the AMF node, a response message from the NSSF node, and obtaining, based on the response message, allowed network slice selection assistance information NSSAI of a terminal device and service area information corresponding to the allowed NSSAI. The AMF node obtains the allowed network slice selection assistance information NSSAI of the terminal device and the service area information corresponding to the allowed NSSAI from the NSSF node, to avoid repeated interaction between the AMF node and the NSSF node after a registration area change caused because the terminal device moves. Therefore, this improves signaling exchange and processing efficiency and reduces system overheads.
