The control unit 900 is a function unit for controlling the PGW 30. The control unit 900 implements various processes by reading out and executing various programs stored in the storage 940.

The IP mobile communication network interface unit 920 is a function unit through which the PGW 30 is connected to the SGW 35 and/or the PCRF 60 and/or the ePDG 65 and/or the AAA 55 and/or the GW 74.

The storage 940 is a function unit for storing programs, data, and the like necessary for each operation of the PGW 30. The storage 940 is constituted of, for example, a semiconductor memory, a Hard Disk Drive (HDD), or the like.

As illustrated in FIG. 9, the storage 940 stores an EPS bearer context 942. Note that the EPS bearer context includes an EPS bearer context stored for each UE 10, an EPS bearer context stored for each APN, an EPS bearer context stored for each PDN connection, and an EPS bearer context stored for each transfer path and/or bearer.

First, the EPS bearer context for each UE 10 will be described. FIG. 10A illustrates an example of the EPS bearer context for each UE 10. As illustrated in FIG. 10A, the EPS bearer context includes at least an IMSI, an ME identity, an MSISDN, and a UE NBIFOM capability. The IMSI is information for identifying a user of the UE 10. The ME identity is an ID of an ME, and may be the IMEI/IMISV, for example. The MSISDN represents the phone number of the UE 10.
