The components of the sender information providing system 1 of FIG. 1 are generally connected through a network. For example, as shown in FIG. 1, the mobile telephone exchange 100 may be connected to a calling terminal (not shown) and a called terminal 500 via a network. The mobile telephone switching center 100 may be connected to the subscriber information management server 200, the telephone number management server 300 and the spam number management server 400 via a network.

An example of such a network is Wi-Fi, the Internet, a LAN (Local Area Network), a Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area Network), 3G, 4G, LTE and the like.

The mobile telephone exchange 100 receives an incoming call including an origination number and a destination number. The mobile switching center 100 may be, for example, a mobile switching center (MSC) in the 3GPP network and a call session control function (CSCF) center in the 4G and Voice over Long Term Evolution (VoLTE) networks .

The mobile telephone exchange 100 inquires of the subscriber information management server 200 whether the called party corresponding to the called party number is a subscriber to the supplementary service (caller information providing service). That is, the mobile telephone exchange 100 can inquire whether or not the called party is subscribed to the caller information providing service among a plurality of additional services to which the called party subscribes. For example, when the called party is informed from the subscriber information management server 200 that the called party is a subscriber of the supplementary service, the mobile telephone switching center 100 transmits the call origination number and the call origination number And the corresponding sender information can be provided together with the terminal 500 of the called party. For example, when the mobile telephone exchange 100 receives a notification from the subscriber information management server 200 that the called party corresponding to the called party is not a supplementary service subscriber, when the incoming call is connected to the called terminal 500, Only the number can be provided to the terminal 500 of the called party.

When the called party is an additional service subscriber, the mobile telephone exchange 100 inquires of the telephone number management server 300 about the caller information of the caller corresponding to the calling number. At this time, the sender information may include the sender's name, a business name, and the like. For example, when the mobile telephone exchange 100 receives caller information from the telephone number management server 300, when the mobile telephone exchange 100 connects the incoming call to the called terminal 500, It is possible to provide the sender information of the calling party together. For example, when the mobile telephone exchange 100 fails to receive caller information from the telephone number management server 300, when the mobile telephone exchange 100 connects the incoming call to the called terminal 500, the called terminal 500 ) May be notified that the caller information of the incoming call is a spam phone. Alternatively, when the called party is an additional service subscriber, the mobile telephone switching center 100 may directly inquire the calling party information of the caller corresponding to the calling number to the spam number management server 400.

In the 3GPP network, the caller information can be provided to the terminal 500 of the called party using CNAP (Calling Name Presentation). In the 4G and VoLTE networks, the caller information is inserted in the header of the Invite message, The terminal 500 of FIG.

The subscriber information management server 200 receives a request from the mobile telephone switching center 100 to inquire whether the called party corresponding to the called party is a supplementary service subscriber. The subscriber information management server 200 inquires whether the called party of the plurality of supplementary services is subscribed to the caller information providing service and informs the mobile telephone switching center 100 of the inquiry result. At this time, the subscriber information management server 200 may be, for example, a home location register (HLR) in the 3GPP network and a home subscriber server (HSS) in the 4G and VoLTE network.

The telephone number management server 300 provides the inquired caller information to the mobile telephone exchange 100 when the caller information inquiry corresponding to the calling number is requested from the mobile telephone exchange 100. [ For example, when the calling number received from the mobile telephone switching center 100 is '02 -1234-5678 ', the telephone number management server 300 inquires of the calling party information corresponding to the corresponding calling number, Is the 'KT Customer Center', the caller information inquiry result can be provided to the mobile telephone exchange 100.

The spam number management server 400 may determine whether the calling number is a spam number and provide the determination result to the mobile telephone switching center 100. [ For example, if the calling number information corresponding to the calling number is not retrieved from the telephone number management server 300, the spam number management server 400 receives the calling number from the telephone number management server 300, Can be inquired. For example, if the calling number information corresponding to the calling number is not retrieved from the telephone number management server 300, the spam number management server 400 directly receives the calling number from the mobile telephone switching center 100, The number can be inquired. At this time, the spam number management server 400 may be combined with the phone number management server 300, or may be configured independently of each other. Alternatively, the spam number management server 400 may directly retrieve the sender information from the mobile telephone exchange 100 without going through the telephone number management server 300 and inquire.

The called terminal 500 can receive caller information when receiving an incoming call from the mobile telephone switching center 100. For example, assume that the called terminal 500 receives a call connection request from the mobile telephone switching center 100 that includes the calling number of '02 -1234-5678 '. At this time, the called terminal 500 can display the calling number of '02-1234-5678' received from the mobile telephone switching center 100 on the display. In addition, the calling party terminal 500 can display the calling party information corresponding to the calling number received from the mobile telephone switching center 100 on the display. At this time, the sender information may be either the sender's name or the business name.
