說(shuō)明書(shū)

The IP mobile communication network interface unit 1120 is a function unit through which the PCRF 60 is connected to the PGW 30 and/or the TWAG 74 and/or the AAA 55.

The storage 1140 is a function unit for storing programs, data, and the like necessary for each operation of the PCRF 60. The storage 940 is constituted of, for example, a semiconductor memory, a Hard Disk Drive (HDD), or the like.

As illustrated in FIG. 11, the storage 1140 stores UE context 1142. Note that the UE context may be classified into a UE context stored for each UE 10 and a UE context stored for each PDN connection.

FIG. 12A illustrates the UE context for each UE 10. As illustrated in FIG. 12A, the context includes at least a Subscriber ID and UE NBIFOM capability.

The Subscriber ID is identification information on a user. For example, the Subscriber ID may be an IMSI.

The UE NBIFOM capability is the NBIFOM capability of the UE 10. The UE NBIFOM capability is identification information for each UE 10 indicating whether or not capability of establishing the first PDN connection is supported. In other words, the UE NBIFOM capability is identification information indicating whether or not the UE 10 supports the NBIFOM function. More specifically, for example, the NBIFOM capability may include “allowed” or “Not allowed”.
