Description

Integrated management system and apparatus for calling numbers and method

The present invention relates to a communication system, and more particularly, to an integrated caller ID system and apparatus for activating a VoIP service, and a method thereof.

VoIP stands for Voice over internet protocol, also called Internet telephony technology, and refers to a technology that supports not only data but also voice using IP (Internet Protocol), which is a standard protocol in a network.

The biggest advantage of VoIP is that it utilizes existing IP network as it is and integrates telephone service, greatly reducing the line cost of telephone or fax transmission, so that telephone users can make long distance and international phone service in the Internet and intranet environment with only local call fee. Will be able to receive.

In addition, VoIP can manage voice and data traffic on a single device and line, which can be used for applications such as web call centers and desktop video, and, unlike Internet phones, does not require additional gateways and only existing devices such as routers. You can also build

Voice call processing technology can be divided into analog and digital methods, and digital methods are divided into circuit switched (CS) and packet switched (PS). Packet switching is divided into various types according to the backbone. Among them, VoIP is a technology that can reduce communication costs by installing voice on an existing data network without establishing a separate network. It is also easy to build.

These VoIP services have been highly expected in the first commercialization service due to the activation of high-speed Internet service and the strength of low communication rate system. However, since the identification number assigned to the VoIP service is similar to the 0X0 number (for example, 080) recognized as a spam telephone number to users, there is a problem that subscribers avoid subscription. Subscribers who have already subscribed to the VoIP service are increasingly complaining that the other party using the CID (Caller Identification or Calling Number Identification (CNID)) feature misinterprets the number as a spam call and does not answer the call. As a result, a number porting service was introduced that uses existing landline numbers as is and converts them to VoIP, but it does not apply to subscribers who do not have an existing landline number, because of the irrationality of the corresponding number porting method, which increases billing factors. Due to various problems, the effect is insignificant.

Therefore, the technical problem to be achieved by the present invention is to provide an integrated caller ID system and method that can activate the VoIP service.

Another technical problem to be achieved by the present invention is to provide a caller ID integrated management system and method that can organically combine VoIP services and mobile communication services.

It may include. The CS network 102 may include a mobile switching center (MSC) 160, a home location register (HLR) 170, and a visitor location register (VLR) 180.

The CSCF 120 is an entity in charge of a part related to call and session processing, and includes a gateway function, an call control function, a SPD (Serving Profile Database) function, an address processing function, and the like for an incoming call. Include. The gateway function for incoming calls refers to acting as an entry point and performing routing for incoming calls. In addition, it performs service triggering (triggering) for the input call and is responsible for communication with the HSS (130). The outgoing call of the VoIP phone 110 is routed to the UC-TAS 150 by an IMS iFC (initial filter criteria) trigger mechanism of the CSCF 120. The IMS iFC trigger mechanism means that the IMS network 101 performs a trigger to an application server (AS) matching a corresponding condition according to an iFC condition. In the present invention, the originating iFC condition is set to match the UC-TAS 150.

The HSS 130 performs user mobility management between heterogeneous networks and generates security information of a subscriber. The HSS 130 generates data for user authentication, message integrity check, and encryption function support, and supports each service function element authentication procedure. In addition, it checks whether the mobile subscriber can roam and performs network access authority verification function.

The MGCF 140 is a network entity that allows an IMS user and a CS user to communicate with each other and is responsible for signaling conversion for interworking between the IMS network 101 and the CS network 102 (or PSTN) that is an existing network. Although not shown, the MGCF 140 may include a BGCF (Breakout Gateway Control Function), wherein the BGCF is optimally received through number translation for a call that is received from the IMS network 101 to the CS network 102. Select a network.

The UC-TAS 150 stores subscriber information (hereinafter referred to as " call number indication information ") for calling number display, wherein the subscriber information is divided into a calling number for VoIP and a calling number for mobile. Can be set and stored.

Subscriber VoIP caller ID Mobile caller ID Remarks Subscriber 1 One One 1: mobile number
2: VoIP number
3: display restrictions
Default: 1 Subscriber 2 3 One Subscriber 3 2 One Subscriber N One One

Referring to [Table 1], the caller ID display for the subscriber's VoIP call and the mobile call is set to be displayed as a mobile number. The caller ID display for the subscriber's VoIP call is restricted and the mobile call is displayed. Caller ID for the case is set to be displayed as a mobile number. Unless the subscriber has a special setting, it is preferable to set the default values to be displayed as all mobile numbers such as all 1, that is, subscriber 1.

The MSC 160 is responsible for mobility management, location registration / management, authentication, handover, roaming, and the like.

The HLR 170 includes subscriber information and terminal location information, and the terminal location information is included in a signaling address of the VLR 180.

The VLR 180 stores some of the information of the HLR 170 (the current location of the terminal) and is mainly related to call control and service provision.

Figure 2 is a block diagram showing the internal configuration of the integrated calling number management device, that is, the UC-TAS 150 according to an embodiment of the present invention, as shown in the UC-TAS 150 is IUA ( An IMS User Agent (210), a CA Access Adaptation (CAA) 220, a CAMEL Interface (CAMELIF) 230, a Map Interface (MAPIF) 240, and a Database 250 may be included.

The IUA 210 controls the call leg of the IMS network 101 and controls the calling number display setting according to the service information of the calling subscriber, that is, the calling number display information as shown in [Table 1]. . The call leg (or call leg) is a separate segment of call connection, which refers to a logical connection path between a router and a telephony endpoint through a bearer channel or between a router and another endpoint using a session protocol.

The CAA 220 controls the call leg of the CS network 102 and finds a destination number from an IP multimedia routing number (IMRN) to perform re-targeting. The IMRN is IMRN resource information for routing from the MSC 160 to the UC-TAS 150.

The CAMELIF 230 performs a customized applications for mobile network enhanced logic (CAMEL) interface with the CS network 102, and selects and returns an IMRN at the request of the MSC 160.

The MAPIF 240 performs a MAP (Mobile Application Part) interface with the CS network 102.

The DB 250 stores subscriber information including the caller ID information, and stores Session Initiation Protocol (SIP) call information and the IMRN resource information. For example, the subscriber information including the caller ID information may be stored in the SUBS (subscribers) table of the DB, the SIP call information may be stored in a Call table, and the IMRN resource information may be stored in an IMRN table.

3A and 3B illustrate a caller ID display process when VoIP is dialed in the caller ID management method according to an embodiment of the present invention.

3A and 3B, if an outgoing call is attempted from the VoIP phone 110 in step S310, an invitation message INVITE is generated, and an invitation message INVITE generated in the VoIP phone 110 is stored in step S320. It is routed to the UC-TAS 150 by the IMS iFC Trigger mechanism of CSCF 120.

In step S330, the UC-TAS 150 sets the calling number to be displayed according to the calling number display information. More specifically, the IUA 210 of the UC-TAS 150 sets the calling party number related header of the invitation message in the subscriber information table of the DB 250, that is, the calling party number. Set according to the display information. For example, when the calling number display setting is a mobile number, the CID-related header (eg, P-Asserted-Identity header or From header) of the invitation message is set as the mobile number. Or, if the caller ID setting is set to the VoIP number, the header related to the CID of the invitation message is set to the VoIP number. Alternatively, when the caller ID display is set to display restriction, the header value indicating whether caller ID is to be displayed may be set to a value that does not perform caller ID (for example, a privacy header is set to id). In this case, the CID-related header of the invitation message may be configured with a P-Asserted-Identity header as a VoIP number (for example, 0X0-XXXX-XXXX) and a From header as anonymous.

The P-Asserted-Identity header and the From header are both headers used to verify the identity of the sender, and the P-Asserted-Identity header is added to the CID notation because only the From header has a limitation on the CID service. That is, the CID of the calling party is marked on the called terminal according to the value of the P-Asserted-Identity header.

The Privacy header is a header defining whether to provide CID information. If the value is none, it means that no privacy is used, that is, it provides CID information. If the value is id, it means that CID information is not provided. The content of the header information is defined in the standard document of TTAE.IF-RFC3325.

The UC-TAS 150 then forwards the set invitation message to the CSCF 120 for an incoming procedure.

On the other hand, the UC-TAS 150, if the Request-URI (Uniform Resource Identifier) of the invitation message is a feature code for changing the caller ID display setting, and sets the caller ID information of the calling subscriber based on this You can change and end the call. The Request-URI is one of trigger conditions, and means to transfer a call to a corresponding URI.

Figures 4a and 4b shows a caller ID display process when the mobile call from the integrated caller ID management method according to an embodiment of the present invention.

4A and 4B, if the mobile phone 190 attempts to make a call in step S410, the MSC 160 services the UC-TAS 150 by an IN (Intelligent Network) trigger mechanism in step S420. Send a request message (Initial DP).

Subsequently, in step S430, the CAMELIF 230 of the UC-TAS 150 selects an IMRN that can be routed from the DB 250 to the UC-TAS 150 and maps it with the original called number. In step S440, the UC-TAS 150 delivers the mapped IMRN to the MSC 160.

If the MSC 160 changes the target to the mapped IMRN in step S450 to switch the call, the invitation message is routed to the MGCF 140 of the VoIP network, and in step S460, 3GPP IMS of the MGCF 140. The invitation message is routed to the UC-TAS 150 (the CAA 220) by a PSI Routing mechanism.

Subsequently, in step S470, the CAA 220 of the UC-TAS 150 finds the IMRN in the DB 250 by using the Request-URI (IMRN) of the invitation message, and searches the IMRN from the retrieved IMRN to the mapped destination called number. After performing the target change, the CSCF 120 is routed, and the invitation message routed to the CSCF 120 is routed to the UC-TAS 150 by the IMS iFC Trigger mechanism of the CSCF 120.

In step S480, the IUA 210 of the UC-TAS 150 is configured according to the calling party number display setting of the calling subscriber stored in the corresponding table (eg, SUBS (subscribers) table) of the DB 250, that is, according to the calling number display information. Set the calling number to be displayed. For example, as described above, when the calling number display setting is a mobile number, the P-Asserted-Identity header and the From header of the invitation message are set to a mobile number (for example, 01X-XXXX-XXXX). Alternatively, if the caller ID setting is a VoIP number, the P-Asserted-Identity header and the From header of the invitation message are set to a VoIP number (for example, 0X0-XXXX-XXXX). Alternatively, if the caller ID setting is set to display restriction, the P-Asserted-Identity header of the invitation message may be set to a VoIP number (for example, 0X0-XXXX-XXXX), the From header is anonymous, and the Privacy header is id. .

In step S490, the UC-TAS 150 transmits an invitation message in which caller ID is set as described above to the CSCF 120 for an incoming call procedure.

Meanwhile, if the request-URI of the invitation message is a feature code for changing the calling number display setting, the UC-TAS 150 changes the calling number display information setting of the calling subscriber based on this and ends the call. can do.

The present invention can also be embodied as computer readable codes on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored.

Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, and the like. The program code for performing the online advertising method according to the present invention may be a carrier wave ( For example, transmission via the Internet).
