Description

BACKGROUND OF THE INVENTION

This application claims priority benefit of TW Patent Application Ser. No. 105118320 filed 2016 Jun. 8 which is hereby incorporated herein by reference its entirety.

1. FIELD OF THE INVENTION

The present invention is an authentication system and method thereof, and more particularly to an authentication system and method thereof for integrating heterogeneous network.

2. DESCRIPTION OF THE PRIOR ART

Conventional wireless communication transmission only uses a single wireless communication system to transmit data, which allows the access authentication thereof to independently operate, so that the access authentication method purely depends on the technical specifications and technologies of the wireless communication system. For example, 4G LTE transmits IMSI through the terminal or GUTI performs relevant authentications and registrations with its background HSS server to acquire the authorization for network transmission service, and Wi-Fi uses 802.1X authentication to provide the authentication and network access control mechanism and helps the data reach an encryption effect.

The technical content of the U.S. patent application “System and method for heterogeneous carrier aggregation” (US 20130242897) discloses that when accessing the mobile network and transmitting the Wi-Fi, it is required that the terminal Wi-Fi module DHCP function is disabled and the IP address of the mobile network is assigned to the terminal wireless network module to avoid terminal access and errors occurring when transmitting, however, the relevant heterogeneous network access authentication control mechanism is not taken into consideration in the application, and the wireless network and mobile communication network cannot be simultaneously accessed by the terminal device.

In the unified authentication platform controlling heterogeneous network access authentication mechanism disclosed by the technical content of the U.S. patent application “Authentication method and system oriented to heterogeneous network” (US 20150012986), when the terminal device requests to sign in one of the networks, it is requested that the request is sent to the unified authentication platform, after receiving the signal, the unified authentication platform sends the authentication code to the terminal and the network to be accessed. The terminal device transmits the authentication code to the network to be accessed again to verify the authentication code, so as to finish the heterogeneous network access authentication mechanism. However, the application only can allow the terminal device to access a network, which causes operational inconvenience.

In conclusion, how to provide a technical means which can allow the terminal device to communicate with the wireless network and mobile network and perform the transmission in the same time becomes a technical issue to be solved in this field.

The wireless router 12 is used to provide a wireless network service (such as Wi-Fi) for a connecting device. The wireless gateway 13 is connected and configured with the wireless router 12. The heterogeneous network router 11 is connected with the mobile network core system 14 and the wireless router 12 so as to provide a mobile network service (such as, 3G4G mobile communication service) for the connecting device. The authentication server 15 is connected with the wireless gateway 13 and the mobile network core system 14, and the heterogeneous network router 11 is configured with the splitting operation between the wireless router 12 and the heterogeneous network router 11. When an external terminal device 2 (such as, smart phone, tablet, etc.) with a communication function is located in a telecommunication service covering range of the heterogeneous network router 11 and the wireless router 12, then the heterogeneous network router 11 is triggered, to authenticate the terminal device 2 when the terminal device 2 has a heterogeneous network integration access condition, the authentication server 15 is triggered to authenticate the terminal device 2, and after the authentication server 15 finishes the authentication of the terminal device 2, the terminal device 2 is ordered by the heterogeneous network router 11 to communicate with the heterogeneous network router 11 and the wireless router 12 in the same time so as to perform the splitting operation of the telecommunication traffic.

In another embodiment, the authentication server 15 inquiries whether the account of the terminal device 2 subscribes a heterogeneous integrating service or not so as to perform the authentication operation. In another embodiment, the wireless gateway 13 is used to control the data transmission operation or IP assignment operation of the wireless router. In another embodiment, the heterogeneous network router 11 and the wireless router 12 perform the splitting operation of the downlink telecommunication traffic of the terminal device 2. In another embodiment, the heterogeneous network router 11 further selects the wireless router 12 which has better communication service to perform the splitting operation.

Referring to FIG. 2, the authentication method for integrating a heterogeneous network of the second embodiment of the present invention, applied to the authentication system, includes the following steps:

S101: determining whether an external terminal device 2 is located in a service covering range of a heterogeneous network router 11 and one or a plurality of wireless routers 12 of the authentication system or not, wherein the wireless router 12 is configured by the wireless gateway 13 of the authentication system;

S102: enabling the heterogeneous network router 11 to determine that the terminal device 2 has a heterogeneous network integration access condition and the authentication sever 15 of the authentication system is triggered to authenticate the terminal device 2;

S103: after the authentication server 15 finishes the authentication of the terminal device 2, the terminal device 2 is ordered by the heterogeneous network router 11 to communicate with the heterogeneous network router 11 and the wireless router 12 in the same time so as to perform the splitting operation of the telecommunication traffic.

In another embodiment, the authentication server 15 of the authentication method inquiries whether the account of the terminal device 2 subscribes a heterogeneous integrating service or not so as to perform the authentication operation. In another embodiment, the wireless gateway 13 of the authentication method is used to control a data transmission operation or IP assignment operation of the wireless router 12. In another embodiment, the heterogeneous network router 11 and the wireless router 12 of the authentication method perform the splitting operation of the downlink telecommunication traffic of the terminal device 2. In another embodiment, the heterogeneous network router 11 of the authentication method further selects the wireless router 12 which has better communication service to perform the splitting operation.

The operational flow of the authentication system 1 for integrating heterogeneous network with the first embodiment of the present invention is illustrated hereinafter, but the authentication method for integrating heterogeneous network in the second embodiment can also reach the same or similar technical efficacy.

Referring to FIGS. 3-1 and 3-2, when the terminal device 2 is located in a service covering range of a wireless router 12 and the heterogeneous network router 11, i.e. the authentication system is triggered to perform the authentication program. In step 301, when receiving the request, the heterogeneous network router 11 begins to determine whether the terminal device 2 has the access ability of heterogeneous network integrating technology (also has the ability to communicate with the mobile network and the wireless network in the same time) or not. If not, then the system has the access ability of heterogeneous network integrating technology, i.e. enter step 315, the terminal device 2 only uses the mobile network to transmit; if have the access ability of heterogeneous network integrating technology, i.e. enter the step 302, at this time the terminal device 2 begins to communicate with the wireless router 12.

In step 303, whether the communication is successful or not is determined by the wireless router 12. If not, then one proceeds to step 310 to search for other wireless networks to communicate with, and instep 301 further determines whether there are other wireless networks to communicate with or not. If so, then return to the step 302; if not, then enter step 315, and the terminal device 2 only uses the mobile network to transmit.

If the communication is successful, then enter step 304, and the terminal device 2 performs the wireless network authentication. In step 305, the terminal device 2 sends the information relevant to the authentication to the wireless gateway 13 through the wireless router 12. When receiving the authentication request, the wireless gateway 13 transfers the authentication information to the authentication server 15. The authentication server 15 acquires the information relevant to the account of the terminal device from the mobile network core. The authentication information comprises IMSI information, communicating with SSID and other information relevant to the authentication. The authentication server 15 may distinguishes different service rules by the different SSID and authentication information, so that the heterogeneous network integrating technology service and the wireless network service can coexist and efficiently distinguish the different charging type of the account.

The different situations of the charging type of the account are shown in FIGS. 4 and 5, FIG. 4 is the authentication situation of heterogeneous network of high-cost user account, when it is required that the heterogeneous network integrating service is used, it uses SSID as Auto1 to perform the communication (the wireless network service uses SSID as Auto), the authentication server 15 acquires the information relevant to the account thereof, determines that the heterogeneous network terminal 201 describes the heterogeneous network integrating service and is the authorized user of the heterogeneous network integrating service. The steps of the FIG. 4 are described in the following:

S401: determining whether the terminal device 2 has a heterogeneous network integration access condition or not.

S402: the terminal device 2 reporting that it has the heterogeneous network integration access condition.

S403: assigning the terminal device 2 to communicate with the SSID=Auto1.

S404: the terminal device 2 communicating with the SSID=Auto1.

S405: authenticating the terminal device 2.

S406: the authentication server 15 acquiring the authentication information.

S407: successfully authenticating the terminal device 2 (it has the heterogeneous network integration access condition).

S408: acquiring the layer 2 address of all the connected users.

S409: the terminal device 2 reporting that the communication is successful.

S410: activating the heterogeneous network integrating and communicating operations.

FIG. 5 is the authentication situation of heterogeneous network of low-cost user account, due to the too low cost, the authentication server 15 determines that it does not describe the heterogeneous network integrating service and only can use the mobile network to transmit. The steps of the FIG. 5 are described in the following:

S501: determining whether the terminal device 2 has a heterogeneous network integration access condition or not.

S502: the terminal device 2 reporting that it has the heterogeneous network integration access condition.

S503: assigning the terminal device 2 to communicate with the SSID=Auto1.

S504: the terminal device 2 communicating with the SSID=Auto1.

S505: authenticating the terminal device 2.

S506: the authentication server 15 acquiring the authentication information.

S507: successfully authenticating the terminal device 2 (it has the heterogeneous network integration access condition).

S508: terminating the communication of the terminal device 2.

S509: the terminal device 2 reporting that the communication fails.

S510: only using the mobile network to transmit.

In step 306 the authentication server 15 is enabled to determine whether the terminal device 2 has the authority to access and use the heterogeneous network integrating service or not. If not, enter step 311, where the communication between the wireless router 12 and the terminal device 2 is terminated, and the mobile network is only used to transmit; if so, enter step 307, where the heterogeneous network router 11 regularly or irregularly asks the wireless router 12 for the Layer 2 address data of all the connected users.

In step 308, the heterogeneous network router 11 is enabled to further determine whether the Layer 2 identification address of the terminal device 2 exist in the communication terminal list data or not. If not, enter the step 312 and determine whether the time counter is terminated or not (Time out). If the time counter is terminated, enter the step 315, the terminal device 2 only uses the mobile network to transmit; if the time counter is not terminated, then return to the step 308.

If the Layer 2 identification address of the terminal device 2 exist in the communication terminal list data, then enter the step 309, enabling the heterogeneous network router 11 to determine that whether receives the information that the communication of the terminal device 2 is successful or not. If so, enter the step 314, activating the heterogeneous network integrating technology terminal device 2 and using the mobile network and the wireless network to transmit in the same time; if not, enter the step 313, determining whether the time counter is terminated or not.

If the time counter is terminated, then return to the step 315, at this time, the terminal device 2 only uses the mobile network to transmit. If the time counter is not terminated, then return the step 309. The information that the communication is successful is further transmitted by the terminal device 2, so that the unfinished authentication due to the terminal device 2 can be avoided, but the Layer 2 identification address of the terminal device 2 has existed in the communication terminal list data of the wireless router 12, so that erroneous behavior of the authentication occurs.

When finishing the authentication, whether the wireless gateway 13 distributes the IP address to the terminal device 2 or not, the heterogeneous network integrating can be performed. If the wireless gateway 13 distributes the IP address to the terminal device 2, the terminal device 2 also uses the wireless router 12, wireless gateway 13 and the Internet to transmit. If the wireless gateway 13 does not distribute the IP address to the terminal device 2, the erroneous behavior of the terminal device 2 can be avoided. When the terminal device 2 successfully accesses and enters the heterogeneous network integrating service, the downlink telecommunication traffic of the terminal device 2 is transmitted to the heterogeneous network router 11, the heterogeneous network router 11 performs the splitting and transmits the partial downlink telecommunication traffic through the mobile network, and the wireless router 12 transmits the remaining to the terminal device 2 through the wireless network. The terminal device 2 receives the downlink telecommunication traffic transmitted by the heterogeneous network router 11 and the wireless router 12 in the same time, and rebuilds the received downlink telecommunication traffic.
