Title:
SERVICE ACCESS TO DISJOINT NETWORK SLICES
Document Type and Number:
WIPO Patent Application WO/2022/145432
Kind Code:
A1
Abstract:
The disclosure is addressing the service access to disjoint network slices. It proposes solutions for on demand registration to a disjoint network slice(s) and a switch between disjoint network slices with minimum interruption. This allows for isolation between the network slices leading to improved 5G security and integrity in the data exchange.
