[Outline of seamless push]
Figure 1 is a schematic diagram for explaining the push system. Push system shown in Figure 1, is built in the intranet NET1, such as the and school enterprise. Intranet NET1 is protected by a gateway GW, such as a firewall from the outside of the Internet NET2. Therefore, the push system, the intranet NET1, transmits a push requester apparatus Pu-req for requesting the transmission of the push message, a push gateway PGW to send push messages to the terminal SD of the user, the application to the terminal SD and a application server App-ser, it has become connectable to each other via an intranet NET1.
Push requester apparatus Pu-req is a server or a terminal of the service provider that provides a service to push transmit the application to the user of the terminal SD. Push requester apparatus Pu-req requests the push message to the push gateway PGW. Push message is a message to be triggered to download the application to the terminal, for example, it has a download destination information. Push gateway PGW is a server for push communication push messages ask the user of the terminal SD. Then, the application server App-ser is a server to send the application to the terminal SD of the user. Furthermore, the terminal SD of the user, for example a smart phone, and the like smart pad terminal, PC, where a terminal capable of moving even, collectively referred to by, for example, smart device (Smart
Device: SD) referred to as. Terminal SD is, it is possible to a wireless LAN and WiFi connection or in the Internet an Intranet, may be connected to the Internet via a 3G public telephone network.
The push gateway PGW and terminal SD to establish the connection state by the TCP protocol or the like, can maintain its connection state. By thus always connected state terminal SD, the push gateway PGW is at any time push message can be pushed transmitted to the terminal SD. Further, when the push message is pushed transmitted to the terminal SD, terminal SD is connected to the application server App-ser, download an application corresponding to the push message from the application server App-ser, executed in the terminal SD.
General operation is as follows. Advance, the terminal SD is to establish a connection between the push gateway PGW, maintains its connection status. First, push requester apparatus Pu-req transmits a transmission push messages to the push gateway PGW. The push message, push the destination information indicating whether to push transmission to which the terminal SD is attached. In response, the push gateway PGW is a push destination terminal SD which maintains the connected state, to send push messages.
To push the message is, is embedded information, such as the download destination URL. Download application in the terminal SD, based on the download destination information push messages, connected to the application server App-ser, downloads the corresponding application. And terminal SD executes the downloaded application at the terminal SD.
As described above, the terminal SD of the user, if maintaining the connection state between the push gateway PGW, always receives the push message, it is possible to download and install the corresponding application. This enables the push service of the application. Although the application to be used in business are included secret information of the company, since the application server App-ser is installed in a high-security intranet NET1, the risk of confidential information leakage is low. Further, in the push message, it contains confidential information, such as application download destination URL of, since the push requester apparatus Pu-req is installed in the intranet NET1, a security problem is small. Furthermore, the push gateway PGW also and push the destination information for sending push messages, push client's ID, it is necessary to hold the like password PW, since it is installed in the intranet NET1, security top of the problem is small.
As a condition for feeding at any application in the terminal SD, terminal SD is sometimes maintains a connected state with the push gateway PGW. On the other hand, as described above, the push gateway PGW is installed in the intranet NET1. Therefore, when the terminal SD moves from the intranet NET1 Internet NET2, to maintain the connection state between terminals SD and the push gateway PGW is leaving problem because it is blocked to the gateway GW intranet. Furthermore, the terminal was moved to the Internet NET2 SD is also possible to download the application from the application server App-ser, there is a firewall problems due to the gateway GW.
For example, while the terminal SD is connected to the Internet NET2 the terminal SD builds a push system and a communication path within the intranet NET1 by Virtual Private Network VPN, consider be left always connected, and the push gateway PGW It is. However, through the VPN that stretched the terminal SD of the Internet outside the company, a third party that is considered to access the intranet NET1, leaving security on the problem.
[Summary of Seamless Push System
Figure 2 is a schematic diagram for explaining the seamless push system. According to push system of Figure 2, even if the terminal SD of the user has moved to the Internet NET2, it can be fed seamlessly application to the terminal SD.
2, a push requester apparatus Pu-req for intranet NET1, the application server App-ser is the same as FIG. 1 in that arrangement is that the intranet NET1 established the private push gateway Pri-PGW, have established public push gateway Pub-PGW in Internet NET2. Then, both gateway Pri-PGW, and the Pub-PGW are each other cooperate to send and receive predetermined command.
The characteristic feature is, for example, as follows. First, terminal SD in the Internet NET2 can be accessed via the Internet NET2 to the public push gateway Pub-PGW, to establish a connection due to the TCP protocol, retains its connection state.
Second, private push gateway Pri-PGW, the transmission destination information and the push message, and push client information, whereas with a database Pri-DB that stores a retransmission wait push messages, Internet NET2 database Pub-DB public push gateway Pub-PGW being installed, such secret information is not kept in. Database Pub-DB public push gateway Pub-PGW stores only small or no information secrecy such as a terminal SD of the device ID in the connected state. Using this connection state, the private push gateway Pri-PGW can be pushed send push messages to the terminal SD over a public push gateway Pub-PGW and Internet NET2.
Third, the terminal SD, upon receiving the push message, upholstery Virtual Private Network VPN to the application server App-ser push system in the intranet NET1, from the application server App-ser through the VPN communication path to download the application. Moreover, in order to be able to be pushed receive push messages while stretched VPN, terminal SD maintains its connected state to establish a connection with the private push gateway Pri-PGW via VPN.
The VPN is a technology for connecting a terminal on the Internet to a particular local area network (LAN), is what is referred to as remote type VPN of VPN over the Internet. VPN is to prevent unauthorized access, such as snooping or tampering, is a technology that enables secure communications, is a private network that is implemented using a public network such as the Internet. VPN is transmits tunneling encapsulates the packet, it is one of the features that encrypt packets. In the example of FIG. 2, the terminal on the Internet SD in order to obtain a secure communication path to connect to the application server in the intranet, VPN is constructed.
[Schematic operation of the app push]
Figure 3 is a flowchart showing the schematic operation of the app push system of Figure 2. First, both the push gateway Pri-PGW, Pub-PGW is started (ST1), perform initial registration (ST2). In the initial registration, private push gateway Pri-PGW is, public push gateway Pub-PGW of the IP address of the cooperation partner, ID and password PW, push the destination information of the push requester apparatus (destination
To set the ID). The terminal SD, the push destination information, both push gateway Pri-PGW, sets and IP information of Pub-PGW. Then, public push gateway Pub-PGW is, to set the IP address of the private push gateway Pri-PGW of the cooperation partner. Push the destination information (destination
ID, dest), for example which downloads information indicating whether the application of which in the terminal, or it may be a simplified manner the terminal ID (device ID).
Then, the push message is transmitted (ST3). Specifically, the terminal SD establishes a connection with the pre-push gateway PGW maintain its connection state (ST3-1). Then, it transmits a transmission request of the push requester apparatus Pu-req push message to a push gateway PGW (ST3-2), the push gateway PGW pushes send push messages to the terminal SD in connection (ST3-3).
In response, the terminal SD is, download the application to access the application server App-ser, be installed on the inside (ST4). Download and install by the terminal SD is automatically carried out by a dedicated application.
As described above, the seamless push system of Figure 2, the initial registration ST2, the transmission ST3 push messages, and downloading and installing ST4 applications based on push message, providing application push service. Hereinafter, the terminal is an outline operation when moved to the Internet.
[If the terminal SD is within the intranet]
If the terminal SD is in the intranet NET1, it is available for connection to an intranet. In this case, as described in FIG. 1, the private push gateway Pri-PGW is a push message request to push transmitted to the terminal SD in the pre-connected state, via the terminal SD intranet in response thereto to download and install the application to connect to the application server Pri-ser Te.
[If the terminal in the Internet SD is the connection state]
If the terminal SD is in the Internet NET2, it is available for connection to the Internet. The operation will be described the application is sent in this case. First, in advance, between the private push gateway Pri-PGW and public push gateway Pub-PGW, information such as the mutual IP addresses are exchanged, it is set, respectively. Also, private push gateway Pri-PGW is a destination push destination information and is push message, such as a push client information is set in advance, stored in the database Pub-DB, push the destination information to the terminal SD There is set. In addition, the terminal SD terminal ID (device
It has an ID).
The terminal can be connected by 3G and WiFi Internet NET2 SD establishes a connection by a public push gateway Pub-PGW and TCP protocols, keep maintain its connection state. The connection terminal information is recorded in the database Pub-DB public push gateway Pub-PGW. In this state, the push requester apparatus Pu-req sends request for push message (push request) to the private push gateway Pri-PGW. In this case, the terminal SD, so is outside the intranet, the private push gateway Pri-PGW does not maintain the connection state. Therefore, private push gateway Pri-PGW sends a transfer command of the push message to the public push gateway Pub-PGW (push transfer command) with push message. This push transfer command, for example, are transmitted by HTTP protocol.
In response to the push transfer command, the public push gateway Pub-PGW refers to the database Pub-DB, confirm that the terminal SD of the push message destination is in the connected state, the push message to the terminal SD to push send. In response to this, the terminal SD is to build the application server App-ser and virtual private network VPN in the intranet NET1, by accessing the URL embedded in the push message, download the application automatically. Then, an application that has been downloaded, the terminal SD is installed.
As described above, even while the terminal SD can be connected to the Internet NET2, private push gateway Pri-PGW at any time can push send push messages to the terminal SD, it is possible to send the application. Moreover, always connected, the terminal DS without going through a gateway GW, is established for the public push gateway Pub-PGW installed in the Internet NET2. Then, only when downloading an application, the terminal SD is because it make a push system and the private network VPN in the intranet NET1, it can be kept high security. The public push gateway Pub-PGW installed in an Internet NET2 is the connection information between the terminal SD (terminal ID in the connected state (device
ID)) only without holding, push message and does not need to hold the information that is confidential, such as push-destination information and push client information.
[If the terminal in the Internet SD is in the non-connection state]
Moreover, the seamless push system of Figure 2, even if the connection between the terminal SD and the public push gateway Pub-PGW not maintained, when a subsequent connection is established, and in response, the private push gateway Pri unsent push messages stored in the retransmission queue in the database Pri-DB of -PGW can push transmission.
Outline of the operation is as follows. As described above, after the initial registration has been made, the push requester apparatus Pu-req sends a transmission request of the push message to the private push gateway Pri-PGW. Since the destination terminal SD is not in a connected state via the intranet NET1, private push gateway Pri-PGW stores its push message and the push destination information to the retransmission queue in that database Pri-DB. The private push gateway Pri-PGW sends a push transfer command to the public push gateway Pub-PGW.
Public Push Gateway Pub-PGW, if any in the connected state terminal SD via the Internet NET2, a push message transferred push transmission, whereas, if receiving an acknowledge ACK push transmission from the terminal SD, sending a push transmission completion notification command to the private push gateway Pri-PGW. In response thereto, the private push gateway Pri-PGW, the push message stored in the retransmission queue in the database Pri-DB Sent.
However, if the terminal SD is not established a connection with the public push gateway Pub-PGW, public push gateway Pub-PGW can not push send push messages that have been transferred to the terminal SD. Therefore, the push transmission completion notification command is not sent to the private push gateway Pri-PGW, will remains a push message to the retransmission queue in the database Pri-DB.
The terminal SD is or turn ON the power from OFF, then move to a location connected to the Internet, at a connectable state to the Internet NET2, terminal SD is TCP protocol the public push gateway Pub-PGW to establish a connection by. In response to this terminal SD of the connection, the public push gateway Pub-PGW is transmitting a retransmission query command newly connected terminal SD addressed push message inquiring whether retransmission waiting, the private push gateway Pri-PGW to.
Then, private push gateway Pri-PGW checks the retransmission queue in the database Pri-DB, if it is stored retransmission waiting push messages of inquiry has been terminal SD addressed in the retransmission queue, public push transfer command sending the push gateway Pub-PGW. In response to this, the public push gateway Pub-PGW pushes send push messages that have been transferred to the terminal SD. After that, the terminal SD has established a VNP to the application server App-ser, download and install the application.
In the above operation, the public push gateway Pub-PGW that receives the push transfer command, if the time the terminal SD is not established a connection, storing the push message transferred in its database Pub-DB is discard does not, is to avoid that the secret information is exposed on the Internet.
Further, even while the terminal SD is stretched push system and VPN in the intranet, to allow push send push messages, the terminal SD, via the VPN, intranet private push gateway Pri- establishes a connection with the PGW, it is desirable to maintain the connection state. Thus, downloading applications can also receive a push message.
Furthermore, private push gateway Pri-PGW, after transmitting the push transfer command does not receive the push transmission completion notification may be periodically repeated transmission of the push transfer command. Or, in combination with sending a push message within the retransmission queue when it receives a retransmission query command push transfer command, and transmitting the periodically push transfer command for push messages in the retransmission queue good.
As described above, according to the seamless push system by 2, even for terminal SD which has moved into the Internet, while maintaining security of the intranet external systems in the intranet, any time or the terminal SD is connected with the Internet when that has been, it is possible to feed the application to push send push messages.
It will be specifically described below seamless push system and its operation in the present embodiment.
Configuration of seamless push system]
Figure 4 is a block diagram of a seamless push system according to the present embodiment. Similar to FIG. 2, the intranet NET1, a push requester apparatus Pu-req for requesting the transmission of the push message, the private push gateway Pri-PGW to send push messages of the push destination to the terminal SD, an application and the application server app-ser to be downloaded to the terminal SD is provided.
On the other hand, in the Internet NET2, having a public push gateway Pub-PGW to send push messages of the push destination to the terminal SD. The terminal SD is while being located in the intranet NET1 is connected to the intranet, while being located in the Internet NET2 is connected to the Internet. Between the intranet NET1 and the Internet NET2, gateway GW is provided to configure the firewall, the security of the intranet NET1 is maintained.
Private push gateway Pri-PGW from push requester apparatus Pu-req push request receiving unit 11 that receives the transmission request of the push message, accepting a connection request by such TCP protocol from the terminal SD of the push receiving unit 31 in an intranet , maintains the connection state via the intranet, the terminal connection receiving unit 12 to be transmitted to the terminal SD in connection push message, synchronizes the public push gateway Pub-PGW transmission status of the transfer and push messages push message with a gateway linking unit 10 to perform in cooperation, and a database Pri-DB that stores necessary data including confidential information and private information. Push request receiving unit 11, a terminal connection receiving unit 12, gateway coordination unit 10 is realized by installing the software on the server.
The application server App-ser has maintains a database of the application sent into the terminal, the application download unit for receiving an application download from application download unit 33 of the terminal SD (not shown).
On the other hand, the public push gateway Pub-PGW includes a terminal connection receiving unit 22, a gateway linking unit 20, and a database Pub-DB. These are achieved by installing the software on the server. Terminal connection receiving unit 22 accepts the connection request by such TCP protocol from the push receiving unit 31 of the terminal SD in the Internet maintains a connection state over the Internet, the terminal being connected to a push message transferred and it sends it to the SD. Gateway linkage unit 20 performs in conjunction with synchronization of a transmission status of the transfer and push messages push message private push gateway Pri-PGW. Database Pub-DB stores the necessary data, except for the secret information or private information. This database Pub-DB is coordination and information such as the IP address of the private push gateway Pri-PGW (cooperation GW information), the terminal SD information (connection terminal building the connection status to the terminal connection receiving unit 22 via the Internet with the information) and.
The terminal SD is pushed reception build a connection with private push gateway Pri-PGW or public push gateway Pub-PGW and TCP protocols, maintaining the connected state, it receives the push message, processing at push message received It has a part 31. This process is like the process for supplying the necessary information included in the push message etc. app download unit 33 and the connection management unit 30.
Furthermore, the terminal SD obtains the URL information of the download destination from the push receiving unit 31 is embedded in the push message, it performs an application download unit 33 to download the management of various connecting an application from the application server App-ser a connection management section 30, and a VPN connection establishing unit 32 to construct the application server App-ser and VPN in the intranet NET1 an instruction from the connection management unit 30. Push receiving unit 31 in the terminal SD, a application download unit 33, a connection management section 30, VPN connection establishing unit 32 are both realized by installing the software in the terminal computer or smart device.
Connection management unit 30 includes information such as private push gateway Pri-PGW and IP address of the public push gateway Pub-PGW, terminal ID (device
And ID), hold the push destination information (destination ID) in the database SD-DB, terminal push the receiver 31 is connected to any of the push gateway according to the network in the connection or, VPN connection to download the application It determines whether or not you need.
Connection management unit 30 performs a network decision in terminals connected as follows. If the terminal SD is via a mobile telephone network such as 3G are connected to the Internet NET2, connection management unit 30 determines that are connected to the Internet NET2, terminal accepting connection portion of the public push gateway Pub-PGW 22 via the Internet to build a connection by TCP protocol. Also, if the terminal SD is connected to the wireless LAN, etc. WiFi, connection manager 30, the identification information of the access point to connect to a wireless LAN (SSID) is, access intranet NET1 registered in advance if it matches the point determines to be connected to the intranet NET1, build a connection by TCP protocol to the terminal accepting connection 12 of the private push gateway Pri-PGW. The connection manager 30, if the SSID of the connected wireless LAN does not match the access point already the registration, it is determined to be connected to the Internet NET2, terminal accepting connection portion of the public push gateway Pub-PGW constructing a connection by TCP protocol 22.
Connection management unit 30, when downloading an application, when connected to the intranet NET1 determines that require the construction of VPN, when connected to the Internet NET2 judged unnecessary.
Private push gateway Pri-PGW and public push gateway Pub-PGW terminal connection receiving unit 12 and 22, the push receiving unit 31 of the terminal SD, when constructing a connection by TCP protocol, ready to socket connection has been completed, socket descriptor identifying the socket connection (IP address and port number), together with the terminal ID that was constructed connection (device), each database Pri-DB,
Pub-DB, is stored in the SD-DB.
When the socket connection is established, the connection state is maintained for the both push gateway and the terminal SD can be transmitted and received data in socket communication. For example, the terminal connection receiving unit 12 of the private push gateway Pri-PGW is not ready to wait for request for socket communication, terminal SD makes a connection request socket communication. Terminal SD is preferably performed automatically when connecting the connection request to the power supply start-up and the Internet or intranet. However, it is also possible to perform manually the user by setting.
The TCP state of the protocol by socket connections are generally as long as the connection of the mobile telephone network or wireless LAN without interruption is maintained. However, if the mobile phone network, it may disconnect condition is not performed for a certain period of time communications by the carrier, such a case, the push receiving unit 31 of the terminal SD is periodically terminal connection receiving unit 12 It communicates with 22, to maintain the connection state.
Push receiving unit 31 in the terminal SD, a VPN connection establishing unit 32, the application download unit 33 is realized by installing the respective application to the terminal SD. VPN connection establishment unit 32, performs a process of building a virtual private network VPN to the application server App-ser. For example, "Android
It can be realized by using a VPN Framework ".
Application download unit 33 performs the process of downloading the application from the application server App-ser through the VPN constructed.
Then, the push receiving unit 31, in addition to the process of maintaining and constructing a communication according to the above TCP protocol, performs a process of constructing a connection with private push gateway Pri-PGW while VPN is built. This is because if the VPN is built, the terminal SD is because it becomes impossible to perform an Internet connection, it is impossible to immediately receive push message when sent request therebetween push message.
[About the data in the database]
Figure 5 is a push gateway Pri-PGW,
It is a diagram illustrating a database of Pub-PGW and terminal DS. Private push gateway Pri-PGW database Pri-DB, a push client information D1, push the destination information D2 which is the destination information of the push message, sent push with the retransmission queue D3, the transmitted push messages and D4, and the connection terminal information D5, and coordination gateway information D6 (such as the IP address of the other PGW) is stored. Data D1, D2, D3, D4 are included confidential information or personal information.
The database Pub-DB public push gateway Pub-PGW, and connection terminal information D5, and coordination gateway information D6 is stored. These information D5, D6 does not have the secret information or private information.
In addition, the database SD-DB terminal SD, a private push gateway Pri-PGW that is associated with an intranet, and information D10, D11 of the respective IP address of the public push gateway Pub-PGW associated with the Internet, and the terminal ID (device1) D12, a transmission destination information D13 of the push message, the terminal and the push gateway Pri-PGW, and the connection information D14 between Pub-PGW stored.
Push client information D1 is authenticated the necessary identification information P-ID of the push requester terminal when pushing requester apparatus Pu-req is a request for sending push messages to the private push gateway Pri-PGW information (password) and a PW. Based on these push client information D1, the push request receiving unit 11 in the private push gateway Pri-PGW authenticates the transmission request of the push messages. Push client information D1 is registered in advance by default.
Push destination information D2, D13 is the transmission destination information for transmitting the push message, information identifying which application or download section in which terminal (destination
ID: dest1, dest2, a dest3, etc.). This information terminal ID (device ID: device1, device2 etc.) in association, are stored in the database Pri-DB. Within the terminal SD, a single or multiple applications of the application download unit 33 in response to the application push the desired service is installed. Therefore, the destination information of the push message D2, D15 is desirably identifiable information or application download unit of which terminal SD throat.
If the terminal SD is that only receive a single app push service, destination information D2 of the push message may be the terminal ID of the terminal SD. However, the terminal ID is information for identifying each terminal ID, which is information that can be easily extracted from a third party. Thus, using the terminal ID to push the destination information, which may be fed to the indiscriminate application do not wish from malicious third parties.
In the example of FIG. 5, push the destination information is given for each app push service that declared like to receive the terminal SD, a database Pri-DB private push gateway Pri-PGW, all push destination information D2, the terminal It is stored in association with the ID. According to the example illustrated in FIG. 5, push the destination information dest1 terminal ID to the terminal is device1,
dest2 and (dest1, device1, dest2, device1), push the destination information dest3 (dest3, device2) is registered for the terminal device ID is device3.
On the other hand, the database SD-DB of the terminal SD, a data D12 of the terminal ID device1 is, as a push-destination information D13 registered in the terminal dest1,
dest2 is stored, respectively.
The push destination information, unlike the terminal ID, which is information determined between the application push service and the terminal, a high confidentiality. Therefore, it is avoided to be fed an application that does not want from a malicious third party.
If the retransmission queue D3, when the push request receiving unit 11 of the private push gateway Pri-PGW receives the transmission request of the push message, the terminal SD corresponding to the destination information dest1 the push message is not in the connected state, and its push message push2, is stored and the push destination information dest1.
Connection terminal information D5, the terminal SD push gateway Pri-PGW,
Pub-PGW when building the connection by TCP protocol to the terminal connection receiving unit 12 and 22, a socket identifier socket1 specifying the connection destination IP address and port number,
And socket2, with the correspondence between the terminal ID of each terminal (device1, device2). In the example of FIG. 5, the database Pri-DB, the Pub-DB, as connection terminal information D5 device1, socket1 a device2, socket2 and are stored. However, in practice, it does not connect the terminal information of the same terminal both are stored. Further, in the example of FIG. 5, the database SD-DB terminal, socket1 is stored as terminal connection information D14.
Coordination gateway information D6 is the IP address of the other of the push gateway, each of which cooperate. In the example of FIG. 5, IP1 to private push gateway Pri-PGW is, IP2 is set in the public push gateway Pub-PGW.
[App push operation to the terminal in the intranet (1)]
Figure 6 is a diagram showing an application push operation (1) to the terminal in the intranet of the seamless application push system according to the present embodiment. Figure 7 is a flow diagram illustrating the app push operation. In this example, the terminal SD is located within an intranet NET1, an operation in the case that build the connection by the terminal connection receiving unit 12 and the TCP protocol in a private push gateway Pri-PGW.
By default, the private push gateway Pri-PGW database Pri-DB, and cooperation GW information D6 (Pub-PGW, IP2), the push client information D1 (ID, PW) and push destination information D2 (dest1 , device1) and it has been registered. In addition, the database Pub-DB public push gateway Pub-PGW, registered cooperation GW information D6 (Pri-PGW, IP1), push the destination information dest1 the terminal SD is registered.
First, the terminal SD is a smart device via an intranet NET1 is a connection by TCP protocol requests the terminal connection receiving unit 12 of the private push gateway Pri-PGW, build a connection (S0). Thus, the database Pri-DB private push gateway Pri-PGW, connection terminal information D5 (device1, socket1) is registered.
Thereafter, the push request receiving unit 11 of the private push gateway Pri-PGW from push requester apparatus Pu-req, receives the transmission request of the application push message (S1). The app push message transmission request includes the application push message push1 push destination information dest1.
Push request receiving unit 11, with reference to the push destination information D2 in the database Pri-DB, and acquires the terminal ID (device1) corresponding to the push destination information dest1. Furthermore, the terminal connection receiving unit 12, the terminal device1 by referring to the connection terminal information D5 to confirm that you have built the connection state (S2). Then, the terminal connection receiving unit 12, by utilizing the socket identifier socket1, push send push messages push1 the terminal SD with push destination information dest1 (S3).
In response to this, the terminal SD, push message push1 is sent to push the receiver 31 by the socket identifier socket1, further push message push1 is passed to the application download unit 33 corresponding the push destination information dest1. Then, the push receiving unit 31 of the terminal SD returns a reception notification of the push message (S4). Terminal connection receiving unit 12 of the private push gateway Pri-PGW receives this reception notification, confirming that the push communication is completed by registering the push message push1 the Sent push D4.
Thereafter, the terminal SD, based on the connection management unit 30 is connected to an intranet, without building an application server App-ser and VPN, application download unit 33, based on the URL address of the push message, to access the application server app-ser, download the application, install (S5).
As described above, when the terminal to an intranet NET1 is connectable, the terminal since establish and maintain a connection state with the private push gateway Pri-PGW in the initial operation, the request of the push message is generated in timing, push message is forwarded to the terminal, the application is downloaded automatically.
[App push operation to the terminal in the intranet (2)]
8, FIG. 9 is a diagram showing an application push operation (2) to the terminal in the intranet of the seamless application push system according to the present embodiment. Figure 10 is a flow diagram illustrating the app push operation. In this example, when the terminal SD is located within an intranet NET1 to or not located in the intranet, connected to the terminal connection receiving unit 12 in the private push gateway Pri-PGW is not yet constructed, it is a behavior.
App push operation to the terminal in the intranet (1) as well as, by default, the private push gateway Pri-PGW database Pri-DB, and cooperation GW information D6 (Pub-PGW, IP2), push requester information D1 (ID, PW) and push destination information D2 (dest1, device1) and are registered. In addition, the database Pub-DB public push gateway Pub-PGW, registered cooperation GW information D6 (Pri-PGW, IP1), push the destination information dest1 the terminal SD is registered.
In this example, the terminal SD is a smart device is not established a connection to the private push gateway Pri-PGW, therefore, the terminal SD is not registered in the connection terminal information D5 database Pri-DB (S0) .
As shown in FIG. 8, the push request receiving unit 11 of the private push gateway Pri-PGW from push requester apparatus Pu-req, receives the transmission request of the application push message (S1). The app push message transmission request, and a app push message push1 push destination information dest1.
Push request receiving unit 11, with reference to the push destination information D2 in the database Pri-DB, and acquires the terminal ID (device1) corresponding to the push destination information dest1. Furthermore, the terminal connection receiving unit 12, based on the acquired terminal ID (device1), connected by referring to the terminal information D5, the terminal device1 to ensure they do not yet built a connection state (S2). Therefore, the push request receiving unit 11, the push message transmission request received in the retransmission queue D3 (push1,
dest1) to add a (S13).
As shown in FIG. 9, finally, the terminal SD, via the intranet NET1, the connection by TCP protocol requests the terminal connection receiving unit 12 of the private push gateway Pri-PGW, build a connection (S14). Thereby, the terminal connection receiving unit 12, a database Pri-DB private push gateway Pri-PGW, and registers the connection terminal information D5 (device1, socket1) (S15).
In response, the push request receiving unit 11, with reference to the push destination information D2, connect the extracted push destination information dest1 for terminal device1 establishing, corresponding to the push message is a retransmission queue D3 thereto Check whether it is stored. In this example, the push message (push1, dest1) has been stored in the retransmission queue, the push request receiving unit 11, to push transmitted by the socket identifier socket1 the push message push1 addressed push destination information dest1 (S16) .
In response to this, the terminal SD, the push receiving unit 31 receives the push message push1, further push message push1 is passed to the application download unit 33 corresponding the push destination information dest1. Then, the push receiving unit 31 of the terminal SD returns a reception notification of the push message (S17). Terminal connection receiving unit 12 of the private push gateway Pri-PGW, the mobile receives the acknowledgment, verify that the push communication of push message push1 is completed, the push message push1 in retransmission queue D3 Sent push D4 It is not, to delete from the retransmission queue D3 (S18).
Thereafter, the terminal SD, based on the connection management unit 30 is connected to the private push gateway Pri-PGW over an intranet, without building an application server App-ser and VPN, application download unit 33, push message on the basis of the URL address of the internal, and access to the application server app-ser, download the application, install (S19).
As described above, when the terminal to an intranet NET1 is connectable, even if the terminal when transmission request of the push message is generated is not established a connection state and private push gateway Pri-PGW, then connection at the timing of establishing the push message is forwarded to the terminal, the application is downloaded automatically.
[If the terminal is within the Internet]
Then, the terminal SD is the operation of the seamless push system when connectable to Internet. As outlined in Figure 2, the seamless push system has established a public push gateway Pub-PGW over the Internet, and private push gateway Pri-PGW intranet NET1, and a public push gateway Pub-PGW in the Internet NET2 to make each other cooperation. By installing the public push gateway Pub-PGW on the Internet, which can be connected to the Internet terminal may establish a connection with that public push gateway Pub-PGW maintain its connection state.
In addition, by mutual cooperation and the private push gateway Pri-PGW and the public push gateway Pub-PGW, secret information and personal information is stored in the database Pri-DB of private push gateway Pri-PGW, public push gateway Pub-PGW of the database Pub-DB is not stored such information.
And, between the two push gateway, by the exchange of the following commands to the push message from reliably private push gateway Pri-PGW to be transferred in a timely manner to the public push gateway Pub-PGW, the terminal SD on the Internet so that application push is forwarded.
Figure 11 is a diagram showing a command to be exchanged between the two push gateway. Figure 11 shows the three commands, and their functions and sender PGW and recipient PGW is. These commands, the GW linkage unit 10 in the private push gateway Pri-PGW shown in FIG. 4, is exchanged between the GW coordination unit 20 of the public push gateway Pub-PGW.
Push transfer command CM1, when retransmitting the case of private push gateway Pri-PGW receives the push message transmission request, the push messages in the retransmission queue, the command to be sent to a public push gateway Pub-PGW is there. This command, the push message (push), push the destination information (dest), and is attached the terminal ID (device). In response to receiving the transfer command CM1 for the push message, the public push gateway Pub-PGW, if the terminal ID (device) is checked whether to establish a connection, has established a connection, the based on the socket information (socket) corresponding to the terminal ID, addressed push destination information (dest), it sends the push message (push1).
Retransmission query command CM2, when the terminal in the public push gateway Pub-PGW was constructed to connect to the private push gateway Pri-PGW from the public push gateway Pub-PGW, push message to the terminal is stored in the retransmission queue dolphin whether the query is a command requesting the transfer of the push message when stored. If stored in the retransmission queue, private push gateway Pri-PGW forwards the Push message to a public push gateway Pub-PGW by the push transfer command CM1.
Transmission completion notification command CM3 responds to push transfer command, and sends the public push gateway Pub-PGW is a push message to the terminal connection status, when receiving the push reception notification from the terminal, from the public push gateway Pub-PGW is a command that is sent to the private push gateway Pri-PGW. In response to this transmission completion notification command CM3, private push gateway Pri-PGW moves the push message that was stored in the retransmission queue D3 Sent push D4, to remove from the retransmission queue D3.
Hereinafter, the terminal is located within the Internet, it will be described in the case of pre-built and connected to public push gateway Pub-PGW, the operation of the application push the case where not yet constructed that connection.
[App push operation to the terminal in the Internet (1)]
Figure 12 is a diagram showing an application push operation (1) to the terminal in the Internet seamless app push system according to the present embodiment. 13, FIG. 14 is a flowchart showing the app push operation. This app push operation (1) is an operation in the case where the terminal has already built a connection with terminal connection receiving unit 22 of the public push gateway Pub-PGW. The initial setting is app push operation to the terminal in the intranet (1) The same as (2).
First, the terminal SD is a smart device is in a state connectable to the Internet, it builds a connection by TCP protocol terminal connection receiving unit 22 of the public push gateway Pub-PGW, connected in that database Pub-DA terminal the device ID and (device1) and the socket information (socket1) is registered in the information D5.
In this state, as in FIG. 8, the push request receiving unit 11 of the private push gateway Pri-PGW from push requester apparatus Pu-req, receives the transmission request of the application push message (S1). The app push message transmission request, and a app push message push1 push destination information dest1.
Push request receiving unit 11, with reference to the push destination information D2 in the database Pri-DB, and acquires the terminal ID (device1) corresponding to the push destination information dest1. Furthermore, the terminal connection receiving unit 12, based on the obtained terminal ID (device1), refers to the connection terminal information D5, the terminal device1 to ensure that they are not constructed yet the connection state in the intranet (S2) . Therefore, the push request receiving unit 11, the push message transmission request received in the retransmission queue D3 (push1,
dest1) to an additional registration (S23).
At the same time, the gateway link unit 10 refers to the push destination information D2, and extracts the terminal ID (device1) corresponding to the push destination information dest1 push message transmission request, the public push gateway Pub push transfer command CM1 and it transmits to the gateway linkage unit 20 in -PGW (S24). This push transfer command CM1, push message push1, push the destination information dest1, it includes terminal ID (device1). At this point, the terminal SD is not only viewable with no build a connection state and private push gateway Pri-PGW intranet, there is a possibility that build the connection state in the Internet, push transfer command CM1 There are sent to a public push gateway Pub-PGW.
In response to the push transfer command CM1, a terminal of the terminal connecting portion 22 in the public push gateway Pub-PGW queries the connected terminal information D5 in the database Pub-DB, push message destination (dest1) (device1) but to confirm whether or not the connection (S25). In this example, already terminal SD at step S0 is maintained to build a connection.
Therefore, the terminal connecting portion 22 in the public push gateway Pub-PGW, due socket information (socket1) Connection terminal information D5, the push message transferred with push transfer command CM1 (push1), push the destination information (dest1 ) to push transmission (S26). In response, the terminal SD as acknowledge push message reception reply push receive notification of (push1) to the terminal connection part 22 (S27).
In response to the push reception notification, the gateway link unit 20 of the public push gateway Pub-PGW is the gateway interconnecting part 10 of the private push gateway Pri-PGW, and transmits the transmission completion notification command CM3 (S28). The transmission completion notification command includes information identifying the push message.
In response to this transmission completion notification command CM3 movement, push message request receiving unit 11 of the private push gateway Pri-PGW is a push message in the transmission queue D3 in the database Pri-DB (push1), the transmitted push D4 to (S29). Thus, the push message is sent twice by mistake is avoided.
Further, the terminal SD, in response to the transmission S26 in the above push message, push the receiving unit 31 transfers to the application download unit 33 corresponding the push message (push1) to push the destination information (dest1). Further, the connection management unit 30 detects that the current terminal SD is connected to the Internet, with reference to the URL contained in the push message (push1), the VPN connection establishing unit 32, an intranet NET1 a virtual private network VPN to the application server App-ser of the inner to build (S30). Further, the connection management unit 30, via the VPN, to establish a connection by private push gateway Pri-PGW terminal connection part 12 and the TCP protocol in an intranet NET1 (S30). Thus, the terminal SD is while downloading the application from the application server App-ser by VPN also allows receive push message.
Then, application download unit 33 of the terminal SD, via a VPN, to download an application corresponding from the application server App-ser to the URL of the push in the message, to install (S31).
As described above, by installing the public push gateway Pub-PGW in the Internet, a terminal capable SD is connected to the Internet, it can be maintained to build a connection state to the public push gateway Pub-PGW. Therefore, at the timing of receiving the transmission request of the push message, the terminal can download the application.
In addition, the database Pub-DB public push gateway Pub-PGW in the Internet, and only registered was constructed connection terminal in the terminal ID (device1), push message (push1) and push the destination information (dest1) personal information and confidential information, such as not registered. Therefore, from the database Pub-DB public push gateway Pub-PGW in the Internet, the risk of such personal information or confidential information is leaked is small.
On the other hand, when downloading terminal SD of the application, since the terminal SD downloads an application to build a VPN application server App-ser intranet NET1, it is possible to store the application in the server in the intranet. Moreover, the terminal SD is being downloaded since build a connection with terminal connection receiving unit 12 in the private push gateway Pri-PGW via the VPN, it is possible to receive even push messages being downloaded.
[App push operation to the terminal in the Internet (2)]
15, FIG. 16 is a diagram showing an application push operation (2) to the terminal in the Internet seamless app push system according to the present embodiment. 17, 18, 19 is a flowchart showing the app push operation. This app push operation (2), the terminal is initially not building a connected state with the terminal connection receiving unit 22 of the public push gateway Pub-PGW, an operation in the case of constructing a subsequent connection state. The initial setting is app push operation to the terminal in the intranet (1) The same as (2).
15, as shown in FIG. 17, first, the terminal SD is a smart device is not build yet connection is established between the public push gateway Pub-PGW in the Internet NET2 (S0). Then, the push request receiving unit 11 of the private push gateway Pri-PGW is, the step of receiving a push message transmission request from the push requester apparatus Pu-req (S1), the gateway link unit 10 in the private push gateway Pri-PGW the push transfer command CM1 to step (S24) of transmitting to the gateway linkage unit 20 of the public push gateway Pub-PGW is similar to app push operation to the terminal in the Internet (1).
In public push gateway Pub-PGW, in response to a push transfer command CM1, terminal connection receiving unit 12 queries the connected terminal information D5 in the database Pub-DB, a terminal ID attached to the push transfer command CM1 (device1 ) it is already checked whether the building connections, to ensure that is not connected (S35). Along with this, the gateway link unit 20 of the public push gateway Pub-PGW is push messages push1 was attached to the push transfer command CM1, discards the push destination dest1. That is, information that contains these personal information or secret information is not stored in the database Pub-DB.
The terminal ID that is attached to the push transfer command CM1 (device1) may be discarded, may be stored as a terminal ID notified by the push transfer command in the database Pub-DB as described below.
Next, as shown in Figure 16, Figure 18, Figure 19, the terminal SD is a smart device, via the Internet, to establish a connection with the TCP protocol to the terminal connection receiving unit 22 of the public push gateway Pub-PGW ( S41). This connection establishment, terminal connection receiving unit 22, the connection terminal information D5 in the database Pub-DB, a terminal ID as the connection terminal information (device1) registers the socket information (socket1) (S42). The gateway link unit 20 of the public push gateway Pub-PGW is the gateway interconnecting part 10 of the private push gateway Pri-PGW, transmits a retransmission inquiry command CM2 (S43). This command CM2, the step S41, S42 to build a connection state in a terminal ID (device1) is attached.
In response, private push message request receiving unit 11 in the push gateway Pri-PGW is pushed destination information (dest1) database corresponding to the terminal ID attached to retransmit inquiry command CM2 (device1) Pri- extracted from the push destination information D2 in DB, based on the push-destination information (dest1), it searches the retransmission queue D3 in the database Pri-DB, detects the retransmission waiting push message information (push1, dest1) to (S44).
In response, the private push gateway Pri-PGW gateway interconnecting part 10 of a push message push1 detected, push the destination information dest1, the push transfer command CM1 to attach the terminal ID (device1), Public and it transmits to the gateway interconnecting part 20 of the push gateway Pub-PGW (S45).
The subsequent operation is similar to the app push operation to the terminal in the Internet step S25 after the (1) operation.
That is, in response to the push transfer command CM1, a terminal of the terminal connecting portion 22 in the public push gateway Pub-PGW queries the connected terminal information D5 in the database Pub-DB, push message destination (dest1) ( device1) to confirm whether or not the connection (S46). This time, the terminal SD at step S41 is maintained already build the connection.
Therefore, the terminal connecting portion 22 in the public push gateway Pub-PGW, due socket information (socket1) Connection terminal information D5, the push message transferred with push transfer command CM1 (push1), push the destination information (dest1 ) to push transmission (S47). In response, the terminal SD as acknowledge push message reception reply push receive notification of (push1) to the terminal connection part 22 (S48).
In response to the push reception notification, the gateway link unit 20 of the public push gateway Pub-PGW is the gateway interconnecting part 10 of the private push gateway Pri-PGW, and attach the information that identifies the push message (push1), transmission It sends a completion notification command CM3 (S49).
In response to this transmission completion notification command CM3 movement, push message request receiving unit 11 of the private push gateway Pri-PGW is a push message in the transmission queue D3 in the database Pri-DB (push1), the transmitted push D4 to (S50). Thus, the push message is sent twice by mistake is avoided.
Further, the terminal SD, in response to the transmission S47 in the above push message, push the receiving unit 31 transfers to the application download unit 33 corresponding the push message (push1) to push the destination information (dest1). Further, the connection management unit 30 detects that the current terminal SD is connected to the Internet, with reference to the URL contained in the push message (push1), the VPN connection establishing unit 32, an intranet NET1 a virtual private network VPN to the application server App-ser of the inner to build (S51). Further, the connection management unit 30, via the VPN, to establish a connection by private push gateway Pri-PGW terminal connection part 12 and the TCP protocol in an intranet NET1 (S51). Thus, the terminal SD is while downloading the application from the application server App-ser by VPN also allows receive push message.
Then, application download unit 33 of the terminal SD, via a VPN, to download an application corresponding from the application server App-ser to the URL of the push in the message, to install (S52).
As described above, the terminal at the timing of establishing a connection with the public push gateway Pub-PGW via the Internet, push message in the retransmission queue is pushed transmitted to the terminal, the application is downloaded to the terminal.
Moreover, when the transmission request first push message receives a push transfer command CM1 when generated, the public push gateway Pub-PGW, the terminal detects the unconnected, push message push1 push destination has been transferred discard the information dest1. Thus, the public push gateway Pub-PGW, personal information or confidential information is not held, it is possible to maintain high security.
Public Push Gateway Pub-PGW, when receiving the first push transfer command CM1, if the terminal is not connected, may hold the terminal ID (device1). In that case, when the subsequent terminal SD establishes a connection to the public push gateway Pub-PGW, it can be collated with its terminal ID, and confirms that the terminal waiting for retransmission push message. However, the public push gateway Pub-PGW, so does not hold the push message, it is necessary to transmit a retransmission request command in place of the retransmission query command CM1 private push gateway Pri-PGW.
In the above embodiment, if the terminal SD is unable to receive only one push message, push the destination information dest is, since the information indicating which downloading unit of which terminal (download application), push the destination it can be used terminal ID as information. However, the terminal ID is because it is information that can be acquired from the terminal SD, the terminal is expected to be transmitted app push messages at random from a third party.
So, in private push gateway Pri-PGW is every app push service, by issuing a separate push destination information dest is the terminal ID, preferably registered in the terminal SD and private push gateway Pri-PGW. Holding the push destination information dest private push gateway Pri-PGW, it is possible not to retain the public push gateway Pub-PGW, the terminal is to be sent to the app push messages at random from a third party Absent. However, in order to be able to see whether the destination terminal in the public push gateway Pub-PGW has established a connection, to push transfer command CM1, in addition to the push message push and push destination information dest, terminal ID (device) is also attached.
