Abstract
UE (50) includes a mapping information retaining unit (57) that retains association information in which a type of EPS bearer configured in 4G and a type of QoS flow that corresponds to the service quality and is configured in 5G are associated, and a handover executing unit (59) that acquires, by using the association information, association between the EPS bearer configured by the UE (50) and the QoS flow configured by the UE (50), and executes handover between the EPS bearer and the QoS flow associated with each other.
Claims5
A user device that executes handover between a first radio communication system and a second radio communication system, the user device comprising:
- an association information retaining unit that retains association information in which a type of a bearer configured in the first radio communication system and a type of a flow that corresponds to service quality and is configured in the second radio communication system are associated;
- and
- a handover executing unit that executes, by using the association information, handover between the bearer and the flow associated with each other.
A radio communication system that includes a first radio communication system and a second radio communication system, the radio communication system comprising:
- an association information retaining unit that retains association information in which a type of a bearer configured in the first radio communication system and a type of a flow that corresponds to service quality and is configured in the second radio communication system are associated;
- and
- an association information management unit that transmits the association information to a user device that executes handover between the first radio communication system and the second radio communication system.
A radio communication method implemented in a radio communication system that includes a first radio communication system and a second radio communication system, the radio communication method comprising:
- retaining in which a user device retains association information in which a type of a bearer configured in the first radio communication system and a type of a flow that corresponds to service quality and is configured in the second radio communication system are associated;
- and
- executing in which the user device executes handover between the bearer and the flow associated with each other by using the association information.
