Title:
UE AND COMMUNICATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/132451
Kind Code:
A1
Abstract:
The present invention provides a communication control method which, when user equipment (UE) receives the reason value of congestion management and the value of a backoff timer while there is the possibility of network slice information correlated to an established PDU session being updated, realizes congestion management in a state in which there is the possibility of the network slice information correlated to the established PDU session being updated, by use of a backoff timer associated with network slice information that the UE transmitted to a device in a core network and network slice information that the UE received from the device in the core network.
