Description

  The present invention relates to an authentication technique for performing authentication processing of a terminal in cooperation with each other in a plurality of communication networks operated by a communication carrier.

  In network technology, authentication processing for confirming the validity of a user terminal is one of important technologies. There are various authentication techniques according to the network form. For example, the one described in Non-Patent Document 1 is one of the simplest authentication technologies, and a pair of ID and password managed by the terminal or terminal user and the authentication function is transmitted and received between the terminal and the authentication function. To confirm that the terminal is valid. Non-Patent Documents 2 to 4 are authentication technologies in the next generation network (NGN), and verify the validity of a terminal that connects to a certain line and transmits a registration request (SIP Register). In order to confirm, it is checked whether the terminal ID matches the line information.

  By the way, in recent years, communication networks operated by a communication business are connected to each other, and a case where connection authentication to the other communication network is performed using an authentication technique in one communication network is being studied. As a typical example, the one described in Non-Patent Document 5 is known. Non-Patent Document 5 stores authentication information in a mobile network in EAP (Extensible Authentication Protocol), which is an authentication method for a terminal connected to a wireless local area network (LAN) that forms part of a fixed network. SIM (Subscriber Identity Module) card is used. Thereby, the terminal can be connected to the fixed network using the authentication information of the mobile network, and the user does not need to operate the terminal when connecting to the wireless LAN.

The data is sent to the edge function unit 230 via the Wi-Fi access point 220 (step S11). Next, the edge function unit 230 adds circuit identification information to the received authentication request message (step S12), and transfers the authentication request message to the AAA proxy 240 via the router 210 (step S13). The AAA proxy 240 transfers the received authentication request message to the AAA server 120 via the gateways 202 and 102 (step S14). At this time, the AAA proxy 240 is connected to the connection destination by an address resolution means such as a DNS server (not shown) (which may be included in the mobile network 100, the fixed network 200, or the external network 900, but is not limited thereto). A mobile network may be selected from a plurality.

Here, the present embodiment is different from the first embodiment in that terminal identification information of the SIM terminal 10 is included in the authentication request message. Next, the edge function unit 230 adds circuit identification information to the received authentication request message (step S43), and transfers the authentication request message to the AAA proxy 240 via the router 210 (step S44). The AAA proxy 240 transfers the received authentication request message to the AAA server 120 via the gateways 202 and 102 (step S45). At this time, the AAA proxy 240 is connected to the connection destination by an address resolution means such as a DNS server (not shown) (which may be included in the mobile network 100, the fixed network 200, or the external network 900, but is not limited thereto). The mobile network may be selected from a plurality.

  Next, the AAA server 120 extracts SIM information corresponding to the line identification information and the terminal identification information from a predetermined storage unit using the line identification information and the terminal identification information included in the received authentication request message as keys (step S46). The non-SIM terminal 20 is authenticated by the SIM information (step S47).

For example, in each of the above embodiments, the Wi-Fi access point 220 issues an IP address after notifying the SIM terminal 10 or the non-SIM terminal 20 of the authentication result. However, the IP address is issued prior to the authentication process. It may be. In each of the above embodiments, the Wi-Fi access point 220 pays out the IP address to the SIM terminal 10 or the non-SIM terminal 20, but the payout may be performed by another device. For example, a device in the mobile network 100 may issue an IP address.

  In each of the above embodiments, when transmitting the authentication result to the non-SIM terminal 20, the user profile corresponding to the SIM information of the SIM 10 terminal used in the authentication process is transmitted together with the authentication result. Transmission of the user profile is not always necessary.

  In each of the above embodiments, the function as a subscriber premises apparatus and the function as an access point for constructing a wireless LAN in the user's house are integrated in the Wi-Fi access point 220. You may make it mount as another apparatus. In addition, a plurality of access points may be provided in the LAN 300 at the user's home regardless of whether or not they are integrated in the subscriber premises equipment. Furthermore, the mounting form of each device in the mobile network 100 and the fixed network 200 is not questioned, and it can be distributed in a plurality of devices or aggregated in one device. For example, various implementations for managing the subscriber information 125 in the mobile network 100 and implementations for storing and managing the line identification information (and terminal identification information) and the SIM information in association with each other are adopted. be able to.

  Further, in each of the above embodiments, the non-SIM terminal 20 that does not have SIM information performs an authentication process using the SIM information of the SIM terminal 10 by performing an authentication procedure according to the sequence of FIG. 4 or FIG. However, a SIM terminal having SIM information may perform the authentication procedure. That is, in this case, the SIM terminal performs an authentication process using SIM information related to another SIM terminal instead of its own SIM information.

  Further, in each of the above embodiments, since the case where the first communication network is the mobile network 100 has been illustrated, the example using the SIM information stored in the SIM card as the authentication information in the mobile network 100 has been described. If authentication is possible, other authentication information may be used. Moreover, although the case where the first communication network is a mobile network has been described in the above embodiment, the present invention can also be applied to other communication networks. For example, the first communication network may be a communication network of a service provider that provides various services to users on the network. For example, the Internet is configured by connecting a plurality of communication networks to each other, and a service (for example, a search service) is provided to a user in one of the configuration networks, and the service is provided. When user authentication is performed, the present invention can be applied with the communication network related to the service provision as the first communication network. That is, it should be noted that the first communication network does not necessarily require direct access means from the user terminal. On the other hand, it should be noted that since the second communication network requires line identification information, it needs to be a fixed network having a subscriber premises apparatus and an access line. Moreover, in the said embodiment, although illustrated about the case where there was one 1st communication network, the case where there are multiple 1st communication networks may be sufficient.
