Description

Method for providing service provider information in number portability service

The present invention relates to a method for providing service provider information in a number portability service. More particularly, the service provider information subscribed to a caller may be texted to a caller in a number portability service that can subscribe to another service provider while using its own original telephone number. It relates to a method for providing.

Conventionally, different identification numbers (for example, 011, 017, 016, 018, 019) are assigned to each mobile communication service provider, and when a caller makes a call to the called party's mobile phone, the called party is called to the caller ID service. By looking at the identification number of the telecommunications carrier indicated by, it was immediately known which telecommunications carrier is the mobile operator to which the caller subscribed. The same is true for landline phones.

However, a number portability system will now be implemented that allows users to change their subscription to a service provider, even if they do not change their phone number. In this case, the service identification recognition by the current carrier identification number will disappear. Accordingly, even in such a case, there is a need for a method for allowing the called party to know where the caller subscribed to.

Therefore, the present invention, when the caller's telephone number is displayed on the called party's telephone by the caller's telephone number display function, by displaying the information of the carrier information subscribed to the called party to the called party, it can give a differentiation and pride to the carrier selection The purpose of the present invention is to provide a service provider information providing method in a number portability service.

According to one embodiment of the present invention for achieving the above object, in a method for providing caller-subscribed carrier information to a called telephone, when a message for requesting location information of the called telephone is input from an originating exchange, A first step of a home location register requesting a service provider's actual registered service provider information to a number portability management database using a caller's telephone number included in the location information request message; A second step of, when the caller receives the service provider information to which the caller is subscribed from the number portability management database, forwarding information of the caller together with the caller's carrier information while requesting routing information to the destination exchange; And a third step of, when the terminating exchange receives a call establishment request from the originating exchange, transmitting the operator information of the originator together with calling the terminating telephone.

Preferably, the home location register analyzes the location information request message and requests business information of the caller only when the calling telephone number is a mobile communication telephone number.

Preferably, the home location register analyzes the location information request message, and analyzes the caller's operator information only for the message requested from the gateway exchange which is the outgoing telephone number being a mobile communication telephone number and a connection path to another communication provider network. request.

Preferably, the number portability management database checks the sender's information at the request of the home location register, and then codes the sender's operator information into a text and transfers the information to the home location register.

Preferably, when the home location register receives the caller's operator information from the number portability management database, the home location register transfers the caller's operator information to the destination exchange by coding a letter.

Preferably, the home location register requests the operator information of the caller through a service server (TIIS), and when the service server receives the caller information from the number portability management database, the service provider of the caller using the caller information. Information is coded and transmitted to the home location register.

Preferably, the home location register analyzes the location information request message, and if it is determined that the caller is a subscriber subscribed to its own network, the caller information of the caller is encoded into a text and the routing information is requested to the destination exchange. The carrier information of the coded sender is transmitted together.

Preferably, the home location register determines whether the caller is a subscriber subscribed to its own network or a subscriber of another service provider through the caller service subscription status information in the location information request message.

Another embodiment of the present invention for achieving the above object is, in the method for providing caller-subscribed carrier information to the destination telephone, after the routing information of the destination exchange in which the called subscriber is located to the originating exchange, When a call establishment request is received from the exchange, the called exchange inquires operator information to a database managing caller's number portability information; And a second step of, when the response to the operator information query is received, the destination exchange calling the destination telephone and transmitting the operator information together.

Preferably, when the number portability management database receives a caller's operator information query from the called exchanger, the number portability management database checks the caller information and codes the text to transmit the operator information of the caller to the destination exchange.

Preferably, when the terminating exchange receives the operator information from the number portability management database, the terminating exchange transmits the coded text to the terminating telephone.

Preferably, the destination exchange requests the operator information of the caller through a service server (TIIS), and when the service server receives the caller information from the number portability management database, the operator information of the caller using the caller information. Is coded as a letter and passed to the destination exchange.

Hereinafter, with reference to the accompanying drawings for the preferred embodiment according to the present invention will be described in detail the configuration and operation.

1 is a diagram illustrating a general number portability service.

In the description of the number portability service of FIG. 1, it is assumed that there are three communication providers. In the illustration of the carrier network, unnecessary network components are omitted to describe the number portability service.

The number portability service will be described with reference to the drawings.

It is assumed that the sender is subscribed to the first carrier network. In addition, it is assumed that the called party was previously subscribed to the second carrier network, but moved to the third carrier network while using the existing telephone number.

When the caller makes a call request using a mobile telephone and is connected to the local exchange 11 of the first carrier network, the local exchange 11 of the first carrier network sends the caller to the gateway (G / W) switch 12. Forward the call request of (101). At this time, the telephone number input from the caller is a telephone number having an identifier of the second communication service provider. The gateway switch 12 requests the location information of the incoming mobile communication telephone to the second communication provider network to which the called party previously belonged through the incoming telephone number (102). The gateway switch 21 of the second telecommunication provider network requests the location information of the called telephone to the called home location register (HLR) 22 (103). Since the called party changed his subscription from the second carrier network to the third carrier network, the home location register 22 of the second carrier network will indicate that the called mobile phone has been changed to another carrier. Therefore, the home location register 22 of the second carrier network notifies the gateway switch 21 that the incoming telephone has been changed to another carrier (104). Then, the gateway switch 21 of the second carrier network notifies the gateway switch 12 of the first carrier network that the called party has changed its subscription to another carrier network (105).

The gateway switch 12 of the first carrier network inquires to the number portability database (NPDB) 13, which manages the number portability information, to which carrier network the incoming telephone has been changed (106). Upon receiving the response to the query (107), the gateway switch 12 requests the location information of the called mobile phone to the gateway switch 31 of the third carrier network to which the called party has moved (108). The gateway switch 31 of the third carrier network requests the location information of the called telephone to the home location register 32 (109). The home location register 32 of the third communication provider network requests routing information from the local switch 33 to which the called telephone belongs, similarly to general call processing, and receives TLDN (Temporary Local Directory Number) as routing information. The home location register 32 then forwards the TLDN, which is routing information, to the gateway exchange 31 (110). Accordingly, the local exchange 33 which is the originating exchange and the terminating exchange is connected (111).

In the process of number portability service as described above, the present invention is performed when an incoming call request is received through a gateway exchange. This will be described with reference to FIGS. 2 to 5.

2 is a view for explaining a process of providing a communication service provider information subscribed to the called party to the called party according to an embodiment of the present invention.

In the figure, the originating exchange may be the gateway exchange of FIG. 1 or, in the case of the same carrier network, may be a specific local exchange. And the destination exchange is a local exchange. The telephony and IP integration system (TIIS) refers to a service node to which home location registers are connected. NPDB is provided for each communication provider and means a database that stores number portability information. A service for providing a service provider information subscribed to by a caller according to the present invention will be referred to as a service provider information display service.

Subscriber must subscribe to this service in order to receive service information display service. This may be provided to all subscribers, but some subscribers do not want to provide the service, so in principle, the information on the service provider should be provided only to the subscribers. In addition, even if the caller is a general wired subscriber, the present service can be provided, but the following description will only be provided for the case where the caller is a mobile communication service subscriber. Here, the mobile communication telephone number identifier includes an 010 identifier according to the number portability service, in addition to the existing operator identifiers (011, 017, 016, 018, 019).

When a location information request message is received from the gateway exchange or a specific local exchange (201), the home location register (HLR) in charge of the called party analyzes the received location information request message. The location information request message includes digit information dialed by the caller, a caller's telephone number, and an exchange identifier. Using this, the home location register checks whether the originating exchange is a gateway exchange or a local exchange, and checks whether the caller is a general telephone subscriber or a mobile communication subscriber through the caller's call. In one embodiment of the present invention, if the caller's telephone number is a mobile telephone number regardless of the calling exchange, the home location register may send a query message through the TIIS to query the number portability database to determine where the caller is currently actually subscribed. Send to (NPDB). This is described below.

If the caller's phone number is a mobile communication phone number, the home location register transmits a service request message to the TIIS to obtain information on the registered service provider. In this case, the service request invocation message, which is the service request message, displays a service information display service on a service identifier, and includes a caller's telephone number and dialed digit information.

If the service identifier is the service provider information display service, the TIIS includes the caller's telephone number included in the message and inquires the service provider information that the caller actually subscribes to the NPDB (203). NPDB searches the database using the calling party's phone number and forwards the current calling party's phone number to TIIS (204). When the TIIS successfully receives a response to the provider information query from the NPDB, the carrier checks the information of the carrier to which the sender is subscribed through the caller's actual phone number included in the received response. For example, SKT => SKT type. In step 205, the caller-subscribed carrier information and the receiver-subscribed carrier information are coded and transmitted to the home location register (205). On the other hand, if the TIIS does not receive a response from the NPDB, it notifies the called home location register to perform the general call processing procedure.

When the home location register receives the coded operator information from the TIIS in response to the service request, the home phone registers the coded operator information while requesting routing information to the destination exchange where the destination phone is currently located (206). On the other hand, when the home location register is notified of the general call processing from the TIIS, it transmits the routing information request to the destination exchange without including the operator information.

The destination exchange sends TLDN information to the home location registrar in response to the routing information request (207). The home location register forwards the TLDN information to the originating exchange (208). Then, when a call setup request is received from the originating exchange (209), the called exchange transfers the operator information received from the home location register to the called telephone together when calling the called telephone.

In the above description, the service provider requests information to NPDB through TIIS, codes the service information to TIIS, and transfers the service information to the home location register. However, it requests business information to NPDB directly from the home location register and delivers the information to the home location register. This information may be transferred to the destination exchange. In this case, the operator information may be coded in letters in the NPDB, or may be coded in letters in the home location register.

On the other hand, in the embodiment of the present invention described in Figure 2 has been described as querying the operator information to the NPDB for all mobile communication telephone numbers, which is the location information request received from the local exchange of the call with the calling number is the mobile communication telephone number Instead of querying the provider information, the provider information may be queried only for the location information request received from the gateway exchange. That is, since the carrier information is already known for the location information request received from the same carrier's own network, the service provider does not request the carrier information, and all the location information requests received through the gateway exchange are not the same. Because it is a call received from, the service provider can request information about them only. The requested exchange can be identified through the exchange identifier included in the location information request message.

FIG. 3 is a diagram for explaining a process of providing operator information when the exchange requesting location information is connected to a local exchange, that is, a caller in the same operator network as the called party.

When the location information request is transmitted from the originating exchange to the home location register, the originating exchange includes the dialed digit, the originating telephone number, the exchange identifier, as well as the service subscriber status information of the calling subscriber in the location information request message (301). ).

The home location register analyzes the contents of the location information request message transmitted from the originating exchange, and if the exchange identifier is the local exchange, and as a result of checking the service subscription status information of the originating subscriber, the originating subscriber is subscribed to the operator information display service. Is coded as a letter, and the carrier information coded with the letter is forwarded together with the destination exchange requesting routing information (302).

The destination exchange delivers routing information to the destination home location register, and the home location register forwards the routing information to the originating exchange (303, 304). The terminating exchange transmits the operator information delivered from the home location register to the terminating telephone when calling the terminating telephone after receiving a call setup request from the originating exchange (305).

When the home location register requests the operator information for the call request of all mobile communication phones, the system may be overloaded. Therefore, it may be desirable to optionally request business information from the home location register. This may be possible by checking the originating telephone number, the exchange identifier, and the service subscription status information of the caller included in the location information request message in the home location register. That is, when the caller is subscribed to the same carrier network, the caller's service subscription status information is transmitted when the location information is requested. Therefore, when the home location register transmits the service subscription status information of the caller, the caller determines that the caller belongs to the same operator network, and does not make a service request to the TIIS. As shown in FIG. Code it and pass it to the destination exchange. Of course, if there is no service subscription status information of the caller, the home location register determines that the caller belongs to another communication service provider network and checks the service provider information through the service request to the TIIS as shown in FIG.

4 and 5 are views for explaining a provider information providing method according to another embodiment of the present invention, which shows a method for providing carrier information in the destination exchange.

The process of requesting call setup from the originating exchange to the destination exchange through the location inquiry through the home location register is performed by the normal processing procedure (401 to 405). When the called exchange receives a call establishment request from the originating exchange, it queries the carrier information with the NPDB for all mobile communication telephone numbers (406). When receiving a response to the query (407), and the call to the destination telephone, the carrier information delivered in the response is delivered together. Here, the NPDB responds by coding the service provider information by text while responding the service provider information to the destination exchange. Alternatively, the destination exchange may receive the operator information from the NPDB, code the operator information into a text message, and transmit the same to the destination telephone.

5 is performed through TIIS in querying provider information from the destination exchange to the NPDB as shown in FIG. That is, when the call exchange request is received from the originating exchange, the terminating exchange makes a service request to acquire the operator information with the TIIS while temporarily holding the call of the terminating telephone (506).

The TIIS queries the NPDB the operator's operator information using the outgoing telephone number transmitted from the destination exchange (507). Upon receiving the response 508 to the query from the NPDB, the TIIS encodes the sender's operator information into text and transmits it to the destination exchange (509). The destination exchange calls the destination telephone as described above, and transmits the transferred carrier information together to the destination telephone.

As described above, according to the present invention, the caller attempts to access a call to the called party's terminal and provides a text message to the called party's subscriber information before the call is made. Information about the cognition can be informed to the called party, and this information can be informed to the user, thereby providing discrimination and pride in the selection of the operator, and providing indirect advertising effects.
