2, when a session is requested to the PGW 108 by the SGW 106 (S100), the PGW 108 determines whether the corresponding UE 100 is a subscriber of the cap rate scheme, The subscriber may send a message to the OCS 116 to initialize the limit control request (S102).

If a message for initializing the limit control request is passed to the OCS 116, the OCS 116 may forward a message to the PGW 108 to initialize the limit control response (S104). The message for initializing this limit control response may include the plan information for the UE 100. [

When a message is provided to initialize the limit control response with the PGW 108, the PGW 108 makes a session response to the SGW 106 (S106), and the SGW 106, in response to the session response of the PGW 108, And perform a session control function for the UE 100. [

Thereafter, the PGW 108 may send a message for updating the limit control request to the OCS 116 (S108). In response to the update of the limit control request, the OCS 116 transmits a message for updating the limit control response To the PGW 108.

At this time, the PGW 108 can check whether the charge limit for the UE 100 is expired through the charge information of the UE 100 provided from the OCS 116 (S112), and it is determined that the charge limit has expired A selective CRC request term according to an exemplary embodiment of the present invention may be transmitted to the OCS 116 (S114). Here, the optional limit control request item may include, for example, a service ID indicating an application-specific delimiter, or a group ID, which is a charge unit division unit.

If an optional limit control request item including this service ID or group ID is transmitted to the OCS 116, the OCS 116 may generate an optional limit control response item corresponding to the optional limit control request item (S116). Here, the optional limit control response item may include optional action information after the expiration of the charge limit, for example, call blocking setting information or default bearer setting information.

An optional limit control response item generated via the OCS 116 may be transmitted to the PGW 108 (S118) and the PGW 108 may perform selective call control corresponding to this optional limit control response item S120).

The selective call control of the PGW 108 can be summarized as shown in Table 1 below.
