The plurality of client interworking units 430 include access information on an interface that can be connected to a wireless network or an internet network. Accordingly, the plurality of client interworking units 430 receives the registration request message through the interface selected by the client terminal and transmits the received registration request message to the controller 420. In addition, the plurality of client interworking units 430 receives a registration completion message for each terminal from the control unit 420 and transmits the registration completion message to the client terminal 100.

The control unit 420 checks the access network information accessed by the client terminal 100 from the registration request messages received through the plurality of client interworking units 430 and selectively performs authentication according to the access network information. Then, a registration completion message of completing the authentication is transmitted to the corresponding client interworking unit 430.

Accordingly, the controller 420 receives the push messages from the plurality of SP interlocking units 410 and routes the push messages to the authenticated client terminal 100 when transmitting them to the corresponding client terminal 100.

In particular, when the controller 420 checks the access network information from the registration request messages received from the plurality of client interworking units 430, when the access network information is the wireless network, the controller 420 performs access authentication for the corresponding client terminal 100. Omit.

In addition, when the access network information is the Internet network, the control unit 420 generates a terminal-specific authentication number for the client terminal 100 and transmits the generated terminal-specific authentication number to the client interworking unit 430 by including the registration completion message in the registration completion message. .

In addition, the controller 420 checks whether the registration request message received from the plurality of client interworking units 430 includes the identification number for the client terminal, and if it does not include the identification number for the client terminal, newly issues and issues it. The identification number is included in the registration completion message and transmitted to the client interworking unit 430.

In this case, the controller 420 routes both the newly issued identification number and the authentication number to the client interworking unit 430 on the registration completion message.

The load balancer 440 receives its state information every predetermined period from the plurality of SP interlocking units 410 and the plurality of Client interlocking units 430, calculates load information of each interlocking unit, and stores the calculated load information. Manage.

Accordingly, when there is a connection request from the service providing apparatus 500 or the client terminal 100, the load balancer 440 may refer to each of the interlocking units 410 and 430 accessible by referring to load information calculated for each of the interlocking units 410 and 430. By allocating to the service providing apparatus 500 or the client terminal 100, the load of each of the interlocking units 410 and 430 is distributed.

Next, a method of connecting between the client terminal 100 and the push service apparatus 400 through the wireless network or the Internet network will be described in detail based on the above configuration.

4 is a flowchart illustrating a push service providing method for performing selective authentication according to an access method of a client according to the present invention.

First, the client terminal 100 receives and provides access information accessible to the push service apparatus 400 (S100 and S110). Accessible access information is information about an interface that can be connected to a wireless network or an Internet network and includes an IP address of a TCP port and an IP address of a TLS port.

Thereafter, the client terminal 100 checks the access network where the terminal is located (S120).

In addition, the client terminal 100 selects the access information, that is, the port IP address, to access the push service apparatus 400 according to the confirmed access network (S130).

Thereafter, the client terminal 100 accesses the push service apparatus 400 with the access information selected (S140).

In this case, connection authentication may be selectively performed according to a case of accessing through a wireless network and a case of accessing through an internet network.

5 is a flowchart specifically illustrating a process in the case of accessing through a wireless network. FIG. 6 is a diagram illustrating a format of a registration request / delete message of FIG. 5, and FIGS. 7 and 8 are diagrams illustrating a payload configuration of a message according to whether a terminal is registered when a client terminal is connected through a wireless network. to be.

First, referring to FIG. 5, when the client terminal 100 of the present invention attempts a TCP connection to the client interworking unit 430 of the push service apparatus 400 through a wireless network, the client terminal 100 may be a client interworking unit ( In step 430, the registration request message is transmitted.

In this case, the registration request message includes at least information about an access network where the client terminal 100 is located.

Thereafter, the client interworking unit 430 of the push service device 400 transmits a registration request message received from the client terminal 100 to the control unit 420 (S210).

Then, the controller 420 checks whether an identification number (ID) for the client terminal is included in the registration request message received from the client interworking unit 430 (S220).

As a result of the check, if the identification number for the client terminal 100 exists, the control unit 420 stores the identification number of the terminal that already exists in the registration request message (S240), and the identification number for the client terminal 100 does not exist. If not, the control unit 420 issues a new identification number for the client terminal (S230). And it stores the issued information (S240).

Thereafter, the control unit 420 transmits a registration completion message including the issued information to the client interworking unit 430, and the client interworking unit 430 transmits a registration completion message to the corresponding client terminal to allow access through the wireless network. (S250, S260).

As such, when attempting to access through a wireless network, the connection between the client terminal 100 and the push service device 400 may be made without going through a separate authentication process. This is because when the client terminal accesses the wireless network subscribed to the service, the wireless network itself undergoes an authentication procedure so that identification can be performed without performing additional authentication for the connection with the push service apparatus 400.

In this case, the registration request message and the registration completion message have the following format.

It may be configured to include a message type field defined for the type of the message, such as an announcement, a push request or a status query, and a message payload field including the content of the message. .

In this format, access network information where the client terminal is located, an identification number (ID) for the client terminal, authentication information, and the like may be included in the message payload field.

For example, as shown in FIG. 7, when accessing through a wireless network and the identification number (ID) for the client terminal is not registered, the message payload field of the registration request message is set to "3G" as access network information (Net-Type). ", And other authentication types (Auth-Type), client terminal number (User-ID), information storage location (Regi-Cnt), operating system information (OS, OS-Ver), the client terminal using the push service Version information (AOMC-Ver), and so on.

In addition, the registration completion message includes the newly issued identification number information (AOMC-ID) for the client terminal.

As another example, when an identification number (ID) for a client terminal is registered in advance and connected through a wireless network, "3G" is recorded as access network information (Net-Type) in a message payload field of a registration request message. Authentication type (Auth-Type), client terminal number (User-ID), information storage location (Regi-Cnt), operating system information (OS, OS-Ver), version information of the client terminal using the push service (AOMC-Ver As well as the identification number information (AOMC-ID) for the client terminal.

The registration completion message includes identification number information and version information of the client terminal.

As such, the registration completion message in the case of connecting via a wireless network does not include authentication information.

In this case, as shown in FIG. 10, the first registration request message includes an internet network "WiFi" as access network information (Net-Type), and other authentication type (Auth-Type) and client terminal number (User-ID). , Information storage location (Regi-Cnt), operating system information (OS, OS-Ver), version information (AOMC-Ver) of the client terminal using the push service, and the like. In addition, when the identification number (ID) for the client terminal is registered in advance, the primary registration request message may also include identification number information for the client terminal.

Thereafter, the client interworking unit 430 of the push service device 400 transmits the primary registration request message received from the client terminal 100 to the control unit 420 (S301).

Then, the control unit 420 checks whether the identification number (ID) for the client terminal is included in the primary registration request message received from the client interlocking unit 430 (S302).

As a result of the check, if the identification number for the client terminal 100 does not exist, the control unit 420 issues a new identification number for the client terminal (S303), or if there is an identification number for the client terminal 100. The controller 420 generates an authentication number for each terminal (S304).

Subsequently, the control unit 420 includes the terminal-specific authentication number generated in the first registration completion message and transmits the same to the client interworking unit 430, and the client interworking unit 430 receiving the terminal is sent to the corresponding client terminal 100. The vehicle registration completion message is transmitted (S305).

Then, the client terminal 100 requests access to the client interworking unit 430 again with the authentication number for each terminal in the first registration completion message provided from the client interworking unit 430 of the push service device 400 (S306). ). In this case, the client terminal 100 transmits a second registration request message including an authentication number for each terminal to the client interworking unit 430.

Thereafter, the client interworking unit 430 transmits the second registration request message received from the client terminal 100 to the controller 420 to request authentication.

The control unit 420 inquires the terminal information and the terminal-specific authentication number included in the second registration request message to the authentication device 600 to request authentication (S307, S308), and then authenticates the authentication result. Received from 600 (S309).

Thereafter, the control unit 420 stores the authentication result (S310), and transmits the second registration completion message including the authentication result information to the corresponding client terminal through the client interworking unit 430 to allow access through the Internet network ( S311).

FIG. 10 illustrates a payload configuration of a message according to a terminal unregistered state when a client terminal accesses through an internet network, and FIG. 11 illustrates a message payload configuration in a state where a terminal is registered in advance. .

Referring only to the characteristic features of each message payload configuration, in FIG. 10, the primary registration request message is recorded by the Internet network "WiFi" as the access network information (Net-Type) together with the terminal information about the client terminal. Accordingly, the first registration completion message provided from the control unit includes a terminal-specific authentication number (that is, authentication information).

In addition, the secondary registration request message includes an authentication number included in the primary registration complete message, access information (TLS connection), response information, and the like.

On the other hand, when the terminal is registered in advance, as shown in FIG. 11, each registration request and completion message may further include an identification number for the client terminal.
