Terminal device, PGW, and TWAG

說明書
Furthermore, in the example of the fourth PDN connectivity procedure, a case has been described in which the UE 10 and the PGW 30 establish the first PDN connection of an operation mode selected by the UE 10 from the operation modes determined based on the operator policy or the operation modes allowed based on the operator policy; however, the fourth PDN connectivity procedure is not limited to this case. The UE 10 may reject the establishment of the first PDN connection.
For example, when the UE 10 does not support the operation mode allowed based on the operator policy and/or when the operation mode allowed based on the operator policy does not comply with the policy of the UE 10, the UE 10 may reject the establishment of the first PDN connection.
In greater detail, the UE 10 may transmit a PDN connectivity reject to the TWAG 74, based on the reception of the PDN Connectivity Accept and/or the seventh identification information included in the PDN Connectivity Accept and/or the PDN connection attribute information and/or the policy of the UE 10.
The UE 10 may transmit the PDN connectivity reject including at least one or more of a PDN connectivity reject message identity (PDN connectivity reject message ID), the Procedure transaction ID, and the Cause. Furthermore, the UE 10 may further include fourth identification information in the PDN connectivity reject. Moreover, the UE 10 may further include the PCO and/or the Tw1 value in the PDN connectivity reject. Note that the UE 10 may transmit the PCO including the fourth identification information.
