3 is a timing diagram illustrating a method of interworking a call and a web service according to an embodiment of the present invention.

Referring to FIG. 3 , first, the user terminal 10 may request a VoIP call connection to the target terminal 20 by transmitting a SIP invite signal to the communication server 100 . The communication server 100 specifies the target terminal 20 through the SIP invite signal received from the user terminal 10, and transmits the SIP invite signal to the target terminal 20 to request a VoIP call from the user terminal 10 can be notified (S2). The target terminal 20 may transmit a SIP Ringing signal to the communication server 100 in response to the SIP invite signal (S3). That is, the target terminal 20 may notify the communication server 100 through the SIP Ringing signal that it has received the VoIP call request and is currently waiting for a response to the target terminal. The communication server 100 may transmit the received SIP Ringing signal to the user terminal 10, including web access information previously registered by the target terminal 20 (S4). The user terminal 10 that has received the SIP Ringing signal and web access information from the communication server 100 may display web access information such as a url access address corresponding to the target terminal 20 along with a call back sound. Here, the user terminal 10 may determine whether to request a web access in response to web access information such as a displayed url access address (S5). When the user terminal 10 transmits a web access request (S6), the communication server 100 connects the user terminal 10 to the web service server 30 using a url connection address, etc., and the user terminal ( 10) to provide a web service (S7). On the other hand, when the user terminal 10 does not transmit the web access request or rejects the web access, the web service may be omitted and a VoIP call connection to the target terminal 20 may be provided (S8).

On the other hand, although not shown, the communication server 100 transmits web access information for the first time when the user terminal 10 makes a VoIP call request to the target terminal 20 , and then the user terminal 10 or the target terminal 20 . At the request of , the web access information may be retransmitted to the user terminal 10 during the VoIP call. That is, after the communication server 100 omits the web service and provides a VoIP call connection to the target terminal 20 (S8), the user terminal 10 or the target terminal 20 communicates with the communication server 100 There may be cases in which a web service provision request signal is transmitted. For example, in the case of a user who makes an inquiry to a customer center of a shopping mall, he or she may wish to continue the consultation while viewing the product to be inquired by directly accessing the web site of the corresponding shopping mall. In this case, the user directly transmits a web service provision request signal to the communication server 100 using the user terminal 10 or requests the target terminal 20 by voice to request the web service provision from the target terminal 20 side. A signal may be transmitted to the communication server 100 . Accordingly, the communication server 100 may receive a web service provision request signal from the user terminal 10 or the target terminal 20 during a VoIP call, and transmit web access information to the user terminal ( 10) can be provided.

Here, when the target terminal 20 transmits the web service provision request signal, it can be transmitted as a SIP re-invite signal, and the communication server 100 corresponds to the target terminal 20 in the SIP re-invite signal. including web access information to be transmitted to the user terminal 10 . In addition, when the user terminal 10 transmits the web service provision request signal, the web service provision request signal may be transmitted using the UI of the application for VoIP call connection of the user terminal. In this case, the communication server 100 may receive a request packet including a web service provision request signal transmitted from the user terminal 10, and the communication server 100 includes web access information in response to the request packet. A response packet may be transmitted to the user terminal 10 .

Thereafter, the communication server 100 may receive a web access request from the user terminal 10 in response to the transmitted web access information, and the communication server 100 connects the web service to the user terminal 10 through a VoIP call. It can be served concurrently with

4 is a flowchart illustrating a method for interworking a call and a web service according to an embodiment of the present invention.

Referring to FIG. 4 , the method for interworking a call and a web service according to an embodiment of the present invention includes a call request step (S100), a search step (S200), a web access information providing step (S300), and a web service providing step ( S400) may be included.

Hereinafter, a method of interworking a call and a web service according to an embodiment of the present invention will be described with reference to FIG. 4 .

In the call request step (S100), the communication server may receive a call request to the target terminal from the user terminal, and transmit the call request to the target terminal. Here, the call connection may be a VoIP call request for requesting a call using a Voice over Internet Protocol (VoIP). Since the call request transmitted by the user terminal includes identification information such as a phone number of the target terminal, it is possible to specify a target terminal to which a call is to be made. According to an embodiment, the user terminal may transmit a VoIP call request as a SIP (Session Initiation Protocol) invite signal. In this case, the received SIP invite signal may be transmitted to the target terminal to request a VoIP call connection.

In the search step (S200), the communication server may search the web access information corresponding to the target terminal from the registered web access information. If the user terminal does not simply support voice calls, but is a terminal that can connect to the Internet, etc., an individual, company, or company that owns the target terminal may want to provide various web services to the user terminal in addition to voice calls. . To this end, individuals, companies, companies, etc. may register web access information together with identification information such as a phone number of their target terminal in the communication server, and the registered web access information may be stored in the communication server. The web access information registered in the communication server may include a uniform resource locator (url) access address of a web page corresponding to the target terminal or application information that provides a web service corresponding to the target terminal. An individual, company, or company that owns the target terminal can operate or manage a web service server for providing web services on the Internet, so the URL (Uniform Resource Locator) access address for accessing the web service server, etc. It may be included in the web access information. In addition, depending on the embodiment, there may be a case in which a separate application for providing a web service is required. In this case, it is necessary to first check whether the application is registered with a user terminal or the like. To this end, application information for providing a web service to the communication server may be registered.

In the web access information providing step (S300), when the communication server receives a response waiting signal corresponding to the call request from the target terminal, the web access information searched for in the response waiting signal may be transmitted to the user terminal. That is, when the communication server transmits the VoIP call request to the target terminal, it may receive a response waiting signal indicating that the VoIP call request has been transmitted and is currently waiting for a response from the target terminal. Thereafter, the communication server may transmit the received response waiting signal to the user terminal, and the user terminal receiving the response waiting signal may output a ring back tone. Here, the step of providing web access information (S300) according to an embodiment of the present invention may further include web access information in the response waiting signal. That is, after receiving the response waiting signal from the target terminal, the communication server may include web access information in the response waiting signal to the user terminal. Accordingly, when there is web access information corresponding to the target terminal, the web access information may be included in the response waiting signal and transmitted to the user terminal. In this case, the user terminal may be provided with web access information corresponding to the target terminal from the communication server, and may select whether to provide a corresponding web service based on the web access information. Meanwhile, when the VoIP call request is received as a SIP invite signal in the call request step S100, a SIP ringing signal may be received as the response waiting signal. In this case, the communication server may provide the web access information to the user terminal in a manner that includes the web access information in the SIP ringing signal.

However, depending on the embodiment, it is also possible for the target terminal to include and transmit web access information such as a url connection address directly in the response waiting signal. That is, the target terminal can include the web access information in the SIP ringing signal and transmit it to the communication server. In this case, the web access information providing step (S300) is a SIP ringing signal between the target terminal and the user terminal using the communication server. By relaying, web access information can be provided to the user terminal. Specifically, the target terminal may transmit the web access information to the user terminal through the call request receiving step and the response waiting signal transmitting step (not shown). First, in the call request receiving step, the target terminal may receive a call request of the user terminal from the communication server, and in this case, the call request may be received in the form of a SIP invite signal as a VoIP call request. In addition, in the response waiting signal transmission step, the target terminal may transmit a response waiting signal including web access information to the user terminal in response to the call request. Here, the SIP ringing signal may be utilized as a response waiting signal, and web access information may be included in the SIP ringing signal and transmitted.

In the web service providing step (S400), when the communication server receives a web access request from the user terminal, it can provide a web service corresponding to the web access information to the user terminal. The user terminal receiving the web access information from the communication server may output a message including the web access information on a display unit, etc., and the user may check the web access information through the display unit or the like. Thereafter, when the user selects to receive the web service, a web access request may be transmitted through the user terminal, and the communication server may connect the user terminal to a web service server corresponding to the web access information. Accordingly, the user terminal may be provided with a web service provided by the web service server while waiting for a VoIP call connection to the target terminal.

According to an embodiment, in order for the user terminal to receive the web service, there may be a case in which a procedure such as a user's login is required. In this case, according to the setting of the user terminal), it is possible for the communication server to perform automatic log-in to each web service server or the like. That is, the communication server provides the user terminal with communication services, such as the user's name, address, user ID (Identification), phone number and USIM (Universal Subscriber Identity Module) information of the user terminal, serial number, model name, IMEI ( User information such as International Mobile Equipment Identity) may be known in advance. Furthermore, when logging in to the web service server, when using an SD (Secure Digital) memory for authentication, a USB (Universal Serial Bus) ID card, etc., SD memory information for authentication and USB ID card information are also transmitted as the user information. It may be included in the server 100 . Accordingly, the communication server may automatically log in to each web service by using user information according to the settings of the user terminal.

Meanwhile, after receiving a web access request from a user terminal and providing a web service, there may be a case where the target terminal responds to the VoIP call request. In this case, the communication server may provide a web service and a VoIP call connection to the user terminal in parallel, or may provide only one of a web service and a VoIP call connection. Here, whether to provide the web service and the VoIP call connection in parallel or to provide only one of the web service and the VoIP call connection may be selected according to a user's input to the user terminal.

Additionally, according to an embodiment of the present invention, in the web access information providing step (S300), the encrypted url access address may be included in the response waiting signal to be transmitted to the user terminal. That is, in order to prevent hacking or phishing due to exposure of url information, the url access address can be encrypted. In this case, in the web service providing step (S400), the received encrypted url access address may be decrypted, and the user terminal may be connected to the web service server based on the decrypted url access address. In addition, in the web access information providing step (S300), instead of transmitting the entire url contact address to the user terminal, the registration number of the url access address or information on whether to access the web page is included in the response waiting signal. As such, it is also possible to prevent the exposure of url information. In this case, in the web service providing step (S400), the user terminal 10 may be connected to the url connection address registered in the communication server.

In addition, when the web access information includes application information for providing a web service, when a web access request is received in the web service providing step ( S400 ), it can be checked whether the application is installed in the user terminal first. Here, when the application is installed, the application may be executed so that the user terminal may be provided with a web service through the application. On the other hand, when the application is not installed, a message indicating whether to install the application is outputted to the user terminal, so that the user can be inquired about whether to install the application. Thereafter, when the user agrees to the installation of the application, the application can be installed and then the application can be executed. On the other hand, when the user does not agree to the application installation, the web service provision may be canceled and the target terminal may wait for a VoIP call response.

Meanwhile, the method for interworking a call and a web service according to an embodiment of the present invention may further include a call connection step (S500), a web access information retransmission step (S600), and a web service provision step (S700) during a call. . That is, after the communication server first transmits web access information when the user terminal makes a call request to the target terminal, by the request of the user terminal or the target terminal, it is also possible to retransmit the web access information to the user terminal during the call. do.

Specifically, in the call connection step (S500), the communication server may receive a web access rejection instead of a web access request from the user terminal. In this case, the communication server omits the provision of the web service to the user terminal, and the target terminal A call connection may be performed between the target terminal and the user terminal in response to the response of . For example, there may be a case where the user who has been provided with the web access information through the web access information providing step S300 determines that the web service is not necessary. In this case, the user may transmit the web access rejection to the communication server using the user terminal, and the communication server receiving the web access rejection may only perform a call connection to the user terminal without providing a web service. Here, even if the user terminal does not transmit the web access request within the preset response time or the target terminal responds to the call request before the user terminal's web access request, it is treated the same as when the user terminal transmits the web access rejection can do.

However, the user may determine that the web service is needed again during a call with the target terminal. For example, in the case of a user who makes an inquiry to a customer center of a shopping mall, he or she may wish to continue the consultation while viewing the product to be inquired by directly accessing the web site of the corresponding shopping mall. In this case, in the method of interworking call and web service according to an embodiment of the present invention, the communication server transmits the web access information to the user terminal again through the web access information retransmission step (S600), so that the user terminal can access the web You may be given the opportunity to receive services. Specifically, the user may directly transmit a web service provision request signal to the communication server using the user terminal, or request the target terminal by voice to transmit the web service provision request signal to the communication server from the target terminal side. Accordingly, the communication server may receive a web service provision request signal from the user terminal or the target terminal during a call, and upon receiving the web service provision request signal, provides web access information to the user terminal, service can be provided.

Here, when the target terminal transmits the web service provision request signal, the communication server may receive the web service provision request signal from the target terminal as a SIP re-invite signal, and the communication server responds to the SIP re-invite signal. Web access information corresponding to the target terminal may be transmitted to the user terminal. Depending on the embodiment, it is also possible for the target terminal to include web access information such as url access address directly in the SIP re-invite signal, and in this case, the communication server relays the SIP re-invite signal between the target terminal and the user terminal. can do. Here, the transmission of the web service provision request signal from the target terminal may be a case in which the user requests to provide the web service to the target terminal by voice. That is, the counselor on the target terminal side who listens to the user's voice may transmit the web service provision request signal to the communication server by manipulating the user interface (UI) of the target terminal. Here, the SIP re-invite signal is used during call transfer between a voice call and a video call among the SIP protocols of the 3rd Generation Partnership Project (3GPP), and it can be modified and utilized.

Meanwhile, according to an embodiment, it is also possible for the user terminal to directly transmit a request packet including a web service provision request signal to the communication server. That is, the user terminal may include an application for VoIP call connection, and a separate UI for transmitting a web service provision request signal may be included in the application. Accordingly, when the user transmits a web service provision request signal through the UI, the communication server may receive a request packet including the web service provision request signal transmitted from the user terminal. In this case, the communication server may transmit a response packet including web access information to the user terminal in response to the request packet. However, depending on the embodiment, the communication server may make a request to the target terminal and the target terminal may generate a response packet including web access information, and the communication server receives the response packet from the target terminal and relays it to the user terminal. It is also possible to perform

Thereafter, when the communication server receives a web access request from the user terminal, such as when the user clicks the url, the web service can be provided to the user terminal through the web service providing step S700 during a call. That is, the communication server may receive a web access request from the user terminal during a call connection, and may provide a web service corresponding to the web access information to the user terminal in parallel with the call connection. Accordingly, it is possible for the user to receive a web service by making a web access request even during a call.
