In particular, SCP 106 may play a role of performing a selective call processing by determining the call type of whether the CDMA / WCDMA plan or the LTE plan based on the call generated in the SGSN (104). For example, SCP 106, if determined to be a CDMA / WCDMA plan, performs call processing in the existing network, and if determined to be an LTE plan, serves to interwork intelligent network call processing to OCS 122. Can be.

In addition, in the embodiment of the present invention, the subscriber information DB 110 managed by the SDP 108 of the intelligent network device 106, 108 to provide a continuous limit service without distinction between the existing network and the LTE network and will be described later.

Here, the call processing protocol of the LTE network may be, for example, a diameter protocol, and the call processing protocol of the existing intelligent network may be, for example, CAM (CAMEL Application Protocol).

Hereinafter, with reference to the above-described configuration, with reference to the timing chart of Figs. 2 and 3 attached to the call processing method in the mobile communication system according to an embodiment of the present invention will be described in detail.

First, in the embodiment of FIG. 2, the UE 100 will be limited to a terminal device of an LTE network plan subscriber, and the LTE plan subscriber is an NB which is a base station equipment of an existing network (for example, a CDMA network or a WCDMA network). A flowchart illustrating an example of making a call attempt through 102.

As shown in FIG. 2, when the UE 100 attempts to connect to the SGSN 104 through the base station equipment NB 102 of the existing network, the SGSN 104 sends an intelligent network protocol to the SCP 106 of the intelligent network device. Call processing request information may be transmitted using S 100.

In this case, the intelligent network protocol may be, for example, a CAP, and the call processing request information may include subscriber information of the UE 100 and plan information (that is, LTE network limit plan information).

When the call processing request information is transmitted to the SCP 106, the SCP 106 may determine the type of the plan based on the subscriber information and the plan information included in the call processing request information (S102).

In the case of the existing network plan subscriber, the intelligent network processing and call processing in the existing network will be performed. However, since the embodiment of FIG. 2 illustrates the case where the plan subscriber of the LTE network is connected to the existing network, the SCP 106 performs such a process. It is determined whether the subscriber is an LTE network plan according to the type of plan, and the call processing request information including the LTE network limit plan information may be transmitted to the OCS 122 which is a billing device of the LTE network (S104). Even in this case, the above-described CAP may be used.

Receiving call processing request information from SCP 106 of the existing network, the OCS 122 of the LTE network may convert the existing network protocol (CAP) into a protocol of the LTE network (for example, a diamond protocol) ( S106), the subscriber information of the UE 100 included in the call processing request information provided from the SCP 106 can be confirmed based on the result of the protocol conversion (S108).

The OCS 122, which is a device, may transmit call processing request information using the LTE network protocol (S200).

In this case, the LTE network protocol may be, for example, a diamond protocol, and the call processing request information may include subscriber information of the UE 100, plan information (that is, WCDMA network limit plan information), and the like.

When the call processing request information is transmitted to the OCS 122, the OCS 122 may determine the type of the plan based on the plan information included in the call processing request information (S202).

In the LTE network plan subscriber, the call processing process in the LTE network will be performed. However, since the embodiment of FIG. 3 illustrates a case in which the plan subscriber of the existing WCDMA network accesses the LTE network, the OCS 122 plans such a plan. By determining whether the subscriber is a WCDMA network plan according to the type, the subscriber information of the WCDMA network may be requested to the SDP 108 (S204).

In response to a request for subscriber information from the OCS 122 of the LTE network, the SDP 108 of the WCDMA network may convert a protocol (diameter protocol) of the LTE network into a protocol (CAP) of the WCDMA network (S206). Based on the conversion result, the information of the corresponding subscriber may be confirmed through the subscriber information DB 110 connected to the SDP 108 (S208).

Thereafter, the SDP 108 may provide the subscriber information response message to the OCS 122 (S210), and the OCS 122 transmits the call processing response message including the subscriber information response message provided from the SDP 108 to the LTE network. It can be delivered to the PGW 118 that is the gateway device of the. In providing such call processing response information, the above-described diagrammatic protocol may be used.

Here, the call attempt message from the PGW 118 may be based on the diamond protocol, and the call attempt message from the SCP 106 may be based on the CAP. In addition, the receiver 402 may receive a subscriber information response message from the SDP 108 which is an intelligent network device of a WCDMA network.

The call type determination unit 404 may serve to determine a call type for whether an LTE network plan call or a WCDMA network plan call is made to the call generated from the PGW 108 provided through the receiver 402.

The subscriber information request message generation unit 406 requests the subscriber information to the SDP 108 of the WCDMA network in which the corresponding plan is accepted when the call type determination unit 404 determines that the WCDMA network plan is called. It can play a role in generating a message.

The transmitter 408 may serve to transmit the subscriber information request message generated through the subscriber information request message generator 406 to the SDP 108.

The protocol conversion unit 410 may play a role of converting a protocol for interworking with SCP 106, which is an intelligent network device of a WCDMA network. For example, a CAP, which is a protocol of a WCDMA network, may be converted into a diagram protocol of a protocol of an LTE network.
