Title: USER EQUIPMENT, WIRELESS COMMUNICATION SYSTEM, AND WIRELESS COMMUNICATION METHOD
Abstract:
This UE (50) is provided with: a mapping information retention unit (57) which holds correspondence information in which the type of an EPS bearer established in a 4G system is correlated with the type of a QoS flow that is established in a 5G system so as to correspond to service quality; and a handover execution unit (59) which, using said correspondence information, acquires the correlation between the EPS bearer established by the UE (50) and the QoS flow established by the UE (50) and executes a handover between the mutually correlated EPS bearer and QoS flow.
