User terminal and access point
First Claim
1. A communication system in which supports cellular communication in a Long Term Evolution (LTE) system and Wireless Local Area Network (WLAN) communication, comprising:
- a base station; and
a user terminal, whereinthe base station transmits first information to the user terminal in a state where a predetermined data bearer is established, wherein the predetermined data bearer is a first data bearer between the base station and the user terminal, and the first information is for establishing a second data bearer between the base station and the user terminal,the user terminal receives the first information from the base station in the state where the predetermined data bearer is established,the first data bearer passes through the base station without passing through an access point,the second data bearer;
passes through the base station and the access point; and
is for aggregation in which the cellular communication and the WLAN communication are used to communicate data of the user terminal,the first information includes a bearer identifier indicating the already established predetermined data bearer and type information associated with the bearer identifier, andthe user terminal starts control to change the predetermined data bearer from the first data bearer to the second data bearer if the type information indicates a change from the first data bearer to the second data bearer.

Abstract
In a communication system according to an embodiment, a base station transmits first information for establishing a second data bearer, to a user terminal in a state where a predetermined data bearer is established. The predetermined data bearer is a first data bearer passes through the base station without passing through an access point. The second data bearer: passes through the base station and the access point; and is for aggregation in which the cellular communication and the WLAN communication are used to communicate data of the user terminal. The first information includes a bearer identifier indicating the predetermined data bearer and type information associated with the bearer identifier. The user terminal starts control to change the predetermined data bearer from the first data bearer to the second data bearer if the type information indicates a change from the first data bearer to the second data bearer.
