摘要

A user terminal transmits and/or receives downlink traffic through cellular/WLAN aggregation by using a first communication and a second communication. The downlink traffic is divided into traffic for cellular communication network and traffic for WLAN. The user terminal further transmits an uplink control signal through the cellular/WLAN aggregation by using the first communication and without using the second communication. The user terminal further notifies the base station of a report regarding the second communication by the first communication. The report indicates a radio link failure in the second communication and includes a reason for the radio link failure. The reason includes a first reason and a second reason. The first reason relates to a radio environment in the second communication. The second reason does not relate to the radio environment.

說明書

Alternatively, the UE 100 may start the cellular/WLAN aggregation when detecting that QoS in the WLAN communication is not satisfied. When a WLAN identifier of a node configured to support the cellular/WLAN aggregation is notified to the UE 100, the UE 100 preferably performs a process to start the cellular/WLAN aggregation after confirming that a connection destination node of the WLAN communication supports the cellular/WLAN aggregation.

FIG. 21 is a diagram showing an operation according to the seventh embodiment. Here, a case in which the UE 100 detects that QoS in the WLAN communication is not satisfied, is assumed.

As shown in FIG. 21, in step S701, the UE 100 transmits by the cellular communication, to the E-UTRAN 10 (eNB 200), a notification indicating that QoS in the WLAN communication is not satisfied.

In step S702, the E-UTRAN 10 transmits, to the UE 100, setting information for starting the cellular/WLAN aggregation, in response to the notification from the UE 100.

In step S703, the UE 100 starts the cellular/WLAN aggregation, on the basis of the setting information from the E-UTRAN 10.

[Eighth Embodiment]

Next, an eighth embodiment will be described. A system configuration, a basic operation of a UE-initiated switching control, a basic operation of cellular/WLAN aggregation, and an operation environment according to the eighth embodiment is similar to those of the first embodiment.
