Document Type and Number:

WIPO Patent Application WO/2020/100719

Kind Code:

A1

Abstract:

Provided is a communication means for implementing an error process in a user device and an error process in a control device in a core network when local area data network (LADN) connectivity cannot be provided, or cannot be modified, in 5GS. Also provided is a communication means for implementing an error process where a control device in a core network denies a request from a user device when local area data network (LADN) connectivity cannot be provided, or cannot be modified, in 5GS. Further provided is a communication means for implementing a suitable error process, performed by a user device, when a request to establish connectivity with an LADN has been denied, or when LADN connectivity cannot be modified.
