Title:
SLICE INFORMATION CHANGING METHOD, AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/169283
Kind Code:
A1
Abstract:
In a system in which user equipment holds a slice type as slice information relating to a slice, which is a virtual network created logically on a network infrastructure, a slice information changing method for changing the slice information includes: a step (S1) in which a slice management unit which manages slices in the system sends a slice type change request to a service management unit which manages services that are processed using a network resource; a step (S2A, S2C) in which the service management unit sends the slice type change request to a processing server which performs processing relating to the user equipment; and a step (S2B, S2D) in which, on the basis of the slice type change request, the processing server performs control to cause the user equipment to update the slice type serving as the slice information held by said user equipment.
