Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The construction of the present invention and the effects thereof will be clearly understood through the following detailed description. Prior to the detailed description of the present invention, the same components will be denoted by the same reference numerals even if they are displayed on different drawings, and the detailed description will be omitted when it is determined that the well-known configuration may obscure the gist of the present invention. do.

4 is a diagram illustrating a push service in a downward direction according to one embodiment of the present specification.

Referring to FIG. 4, the push service providing system may include at least one push service providing apparatus 600a, 600b, 600c,..., 600n, or 600, and a push service gateway (or push service hub 700). Include.

The push service gateway (or push service hub 700) is interworked with a communication network of each operator, and when a push message transmission request is received from the push service providing apparatus 600, the push service gateway 700 is pushed through the communication network of the operator. You can pass a message.

The push service providing apparatus 600 may provide a real time service such as KakaoTalk, My People, Naver Line, Nate On Talk, and the like. In addition, the push service providing apparatus 600 may provide a real time service based on a web or a wireless application protocol (WAP).

When there is a push message to be transmitted to the terminal, the push service providing apparatus 600 transmits a message push request signal including a message to be transmitted to the terminal and terminal identification information to the push service gateway 700. Here, the message push request signal may include a message to be transmitted to the terminal, a message PDU, terminal identification information, push service gateway identification information, a return flag, and the like. Here, the message PDU refers to an application identifier for identifying an application program to transmit a message among application programs included in the terminal, and the reply flag indicates whether a reply to the push service is required.

Here, service data and update data transmitted and received to provide a real-time service may be expressed in a hypertext markup language (HTML) or a wireless markup language (WML).

As described above, the service providing device 600 provides a push service by transmitting only one push request to the push service gateway (or push service hub) 700 without directly making a plurality of push requests to each operator's communication network. As a result, the overhead of the network of the overlayer can be reduced.

When the push service gateway 700 receives the message push request signal including the message and the terminal identification information from the service providing apparatus 600, the push service gateway 700 identifies the communication network of the operator using the terminal identification information and identifies the identification. The push message through the established communication network. In this case, there may be a push server node (not shown) that transmits an actual push message to each terminal in the communication network of each operator.

That is, when the push service gateway 700 receives the push request from the service providing apparatus 600, the push service gateway 700 checks the operators through the terminal identification information and sends a message to the push server node (not shown) in the confirmed operator's communication network. And a push request signal including corresponding terminal identification information. Here, the push request signal may be a signal for requesting a push of a message to a terminal corresponding to the terminal identification information. In this case, the push service gateway 700 may support various types of interface protocols in order to communicate with various types of push server nodes (not shown) that are responsible for transmitting push messages in each operator's communication network. In addition, the push service gateway 700 may convert a push request signal (or message) corresponding to a protocol format required by each push server node (not shown) and transmit the same to a push server node (not shown) of the corresponding operator. . That is, when a push server node (not shown) in each operator's communication network requires a specific type of interface or message format, the push service gateway 700 may generate a push request signal to satisfy the requested interface or message format. Transcoding can be done.

Such a push server node (not shown) is operated by each operator, and when a push request signal is received from the push service gateway 700, the push server nodes (not shown) are terminals corresponding to the terminal identification information included in the push request signal. Send each message. In this case, when the terminal operates in the standby mode, the push server node (not shown) may perform a paging control function for paging the terminal and a push proxy function for transmitting a message using a push service. The terminal identification information includes a telephone number, ID, MAC address, and the like.

On the other hand, examples of the terminal includes a user terminal capable of network communication, such as PC, notebook, laptop, mobile phone, mobile phone, PDA, smart phone.

FIG. 5 is a diagram illustrating a push service in an upward direction according to one embodiment of the present specification. FIG.

As can be seen with reference to FIG. 5, the terminal 100 has various push applications installed in order to receive a service from each push service providing apparatus 600a, 600b, or 600c. In addition, the terminal 100 includes a push middleware (or push service manager) that provides an integrated protocol interface for various push applications.

The push middleware (or push service manager) is connected to the push service gateway 700 through tunneling.

Accordingly, each push application executes the push middleware (or the push service) while executing in the background in the terminal 100 to notify a status signal for informing its status, for example, a keep alive signal or a heart beat signal. Management).

In addition, the push middleware (or push service manager) groups each state signal and transmits the state signals to the push service gateway 700, thereby reducing the load on the communication network. The grouped state signals may be transmitted at regular intervals according to the setting of the push middleware (or push service manager). For example, push application 1 delivers a status signal to the push middleware (or push service manager) every 20 seconds, push application 2 delivers a status signal to the push middleware (or push service manager) every 5 seconds, When the push application 3 transmits a status signal to the push middleware (or push service manager) every 15 seconds, the push middleware (or push service manager) groups all status signals to the push service gateway 700 every 30 seconds. Can be delivered to.

When the push middleware (or push service manager) groups and transmits the status signals, for example, if there are 10 status signals received from each push application for 30 seconds, the 10 push signals are transmitted every 30 seconds. Although transmitted to the gateway 700, only one signal representing the ten status signals may be delivered to the push service gateway 700 every 30 seconds.

On the other hand, when grouping the state signals in this manner and transmits at regular intervals, additional modifications are required to allow the service providing apparatuses 600a, 600b, and 600c to operate normally. That is, each of the service providing apparatuses 600a, 600b, and 600c has received a status signal from each application at each set period. If the service signal is not received at the set period, the service application 600a, 600b, or 600c may determine that each push application does not operate normally. .

Accordingly, after the push service gateway 700 sets a period for transmitting and receiving a status signal with the push middleware (or the push service manager) of the terminal 100, the push service gateway 700 transmits the state signal to each of the push service providing apparatuses 600a, 600b, and 600c. Can be notified. Accordingly, the push service providing apparatuses 600a, 600b, and 600c may recognize that the push service providing apparatuses 600a, 600b, and 600c are not abnormal even if they have elapsed from a period in which a status signal should be received from each push application.

Alternatively, if the push service gateway 700 sets a period for transmitting and receiving a status signal with the push middleware (or push service manager) of the terminal 100, and receives the status signal in the set period, The push service providing apparatuses 600a, 600b, and 600c may transmit a status signal, respectively, in accordance with a period set between each push application and each push service providing apparatus 600a, 600b, or 600c. For example, when the push middleware of the terminal 100 groups all the state signals and transmits them to the push service gateway 700 every 30 seconds, the push service gateway 200 may provide a first push service providing apparatus 600a. ) May transmit a status signal every 20 seconds, the second push service providing apparatus 600b may transmit a status signal every 5 seconds, and the third push service providing apparatus 600c may transmit a status signal every 15 seconds.

6 is a flowchart illustrating a process of delivering a push message in a downward direction to a terminal according to an embodiment of the present specification.

Referring to FIG. 6, the push service providing apparatus 600 obtains terminal identification information for message transmission and transmits a push message transmission request including the obtained terminal identification information and the message to the push service gateway 700. (S601). That is, if there is a message to be transmitted to the terminal 100 using the service provided by the push service providing apparatus 600, the terminal acquires terminal identification information using the service, and includes the terminal identification information and the message. The push message transmission request signal is transmitted to the push service gateway 700.

Then, the push service gateway 700 checks the terminal identification information included in the signal (S602), and identifies the corresponding operator through the terminal identification information (S603). In this case, when the push service gateway 700 includes operator information in the signal and terminal identification information, the push service gateway 700 may immediately determine an operator. Otherwise, the push service gateway 700 determines whether the corresponding terminal is subscribed through the terminal identification information. Operators can be identified by searching through the database of each operator.

Subsequently, the push service gateway 700 may transmit a push message to the terminal through the searched operator's communication network (S604). Alternatively, the push service gateway 700 may search for the push server node of the operator and transmit a push request signal to the retrieved push server node as described above.

FIG. 7 is an exemplary view for explaining a method for enabling a message to be transmitted and received between heterogeneous push services according to another embodiment of the present specification, and FIG. 8 is a signal flowchart illustrating the method shown in FIG. 7 in detail. to be.

As can be seen with reference to FIG. 7, assume that operator 1, operator 2, operator 3, and operator 4 exist.

The first push service providing apparatus 600a (for example, KakaoTalk) provides a push service in an area served by the operator 1 and the operator 4, and the second service providing apparatus 600b in an area served by the operator 2. Suppose that (for example, Google Talk) provides a push service, and a third service providing apparatus 600c (for example, a NAVER line service) provides a push service in an area served by Operator3. In addition, suppose that the services provided by the service providing apparatuses 600a, 600b, and 600c are heterogeneous services such as KakaoTalk, Naver Line, Google Talk, and the like.

In addition, the first push service gateway 700a exists in the area serviced by the operator 1 and the operator 4, the second push service gateway 700b exists in the area serviced by the operator 2, and the area serviced by the operator 3 Assume that the third push service gateway 700c exists.

In this case, the first terminal 100a receiving the first push service (eg, KakaoTalk) from the first push service providing apparatus 600a in the communication network of the operator 1 is located in the communication network of the third operator. There is no conventional method for transmitting a push message from the third push service providing apparatus 600c to the third terminal 100c receiving a third push service (eg, Google Talk).

However, according to the second embodiment of the present specification, this problem is solved through each push service gateway 700a, 700b, and 700c. Specifically, it will be described with reference to FIGS. 7 and 8 as follows.

First, the first terminal 100a is subscribed to the first service of the first push service providing apparatus 600a, and the third terminal 100c is subscribed to the third service of the third push service providing apparatus 600c. There is (S801). Accordingly, each of the push service providing apparatuses 600a and 600c transmits the information of the terminal subscribed to the push service gateways 700a and 700c to the corresponding push service gateways 700a and 700c, respectively (S802). As a result, each push service gateway 700a and 700c may know whether any terminal is subscribed to the push service in charge of the terminal.

 Meanwhile, the first terminal 100a hopes to deliver a push message to the third terminal 100c, and thus transmits the push message to the first push service gateway 700a (S803). In this case, the first terminal 100a may insert identification information of the third terminal 100c which is known to the push message. For example, when the user of the first terminal 100a knows the telephone number of the third terminal 100c, the telephone number may be included in the push message.

Then, the first push service gateway 700a checks identification information of the third terminal 100c to receive the received push message (S804).

If the third terminal 100c is not subscribed to the first push service of the first push service providing apparatus 600a, the first push service gateway 700a receives the heterogeneous push service gateway. A request for inquiry about whether the terminal is subscribed is requested (S805). That is, the first push service gateway 700a transmits an inquiry request signal to the second push service gateway 700b and the third push service gateway 700c to the third terminal 100c which is a receiving terminal.

The push service gateways 700b and 700c receiving the inquiry request inquire whether the third terminal 100c is subscribed to the push service provided by the push service gateways 700b and 700c (S806).

When the third push service gateway 700c checks that the third terminal 100c is subscribed to the push service and the inquiry is completed, the third push service gateway 700c receives subscription confirmation information that notifies the receiving terminal of the third push service gateway 700. The first push service gateway 700a is transmitted to the first push service gateway 700a (S807).

In this case, the subscription confirmation information may include a terminal identification number and information of heterogeneous services, and the information of heterogeneous services may include identification information of the heterogeneous services, interface protocol information of the heterogeneous services, and the like.

When the first push service gateway 700a receives the subscription confirmation information, the first push service gateway 700a confirms that the third terminal 100c is subscribed to the third push service gateway 700c through the subscription confirmation information, and sends a message to the third push service. The controller 700c transmits the message to the gateway 700c and requests the third terminal 100c to transmit the message (S808 and S809).

That is, the third terminal 100c subscribed to the heterogeneous push service from the first terminal 100a which is the originating terminal transmits a message transmitted from the first terminal 100a to the first push service gateway 700a and the third. It may be delivered through the push service gateway 700c.

Here, when there are a plurality of terminals that are subscribed to the first push service and request message transmission to heterogeneous push services, several terminals are grouped, and the inquiry request for the receiving terminals is transmitted by group to reduce network load. Can be

In addition, the controller 704 executes the methods stored in the memory unit 704, and transmits and receives a signal through the transmitter 701 and the receiver 702.

More specifically, the receiving unit 702 of the push service gateway 700 receives a message from the calling terminal subscribed to the push service.

That is, the controller 703 controls the transmitter to transmit a signal for requesting whether the receiving terminal is subscribed to the heterogeneous push service to the device in charge of the heterogeneous push service.

The transmitter 702 transmits a message to the second push service when the information indicating that the receiving terminal is subscribed to the heterogeneous second push service through the receiver is received.

In addition, the reception unit 701 receives subscription confirmation information of the reception terminal from the heterogeneous push service manager. When the receiving terminal is subscribed to the heterogeneous push service responsible device, the information on the heterogeneous service is included.
