Title:
UE AND COMMUNICATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/132452
Kind Code:
A1
Abstract:
Provided is a communication control method which, when a UE receives a congestion management reason value and a back-off timer value in a state in which network slice information associated with an established PDU session has the potential of being updated, realizes congestion management by using a back-off timer associated with network slice information that the UE has transmitted to a device within a core network and network slice information that the UE has received from a device within a core network, in the state in which the network slice information associated with the established PDU session has the potential of being updated.
