Abstract
Provided is communication control accompanied with establishment of a multi-access PDN connection or with rejection of establishment of a multi-access PDN connection, based on a response to a PDN connection establishment request from a terminal device. This makes it possible to provide a communication control method and the like accompanied with a multi-access PDN connection establishment request from the terminal device.
Claims7
A User Equipment (UE) comprising:
- LTE interface circuitry configured to receive an Activate default EPS bearer context request message from a Mobility Management Entity (MME) in order to establish a Packet Data Network (PDN) connection, wherein
- the Activate default EPS bearer context request message includes first information indicating a Network-based IP Flow Mobility (NBIFOM) mode,
- the Activate default EPS bearer context request message further includes second information indicating that a request for a use of NBIFOM is accepted, and
- the NBIFOM mode is selected by a PDN Gateway (PGW) or a Policy and Charging Rules Function (PCRF).
