Problems solved by technology

However, the defect of this solution is that there must be a preset security association between ePDG and PDN GW. When there is no preset security association between ePDG and PDN GW, or ePDG and PDN GW do not know any information about each other , the non-3GPP network cannot access the 3GPP network

Embodiment 1

[0034] An embodiment of the present invention provides a method for a mobile node to access a 3GPP network through a trusted non-3GPP network, such as figure 1 As shown, the method includes:

[0035] 101: During the authentication process between the mobile node and the authentication server, the mobile access gateway obtains the packet data network gateway address and the first shared key between the mobile access gateway and the authentication server;

[0036] Wherein, the authentication server is: authentication-authorization-accounting server (Authentication-Authorization-Accounting Server, AAA Server) or home subscriber server (Home Subscriber Server, HSS), and the authentication server can also be the aggregate of AAA server and home subscriber server , the first shared key is the mobile access gateway-authentication-authorization-accounting key MAG-AAA KEY.

[0037] 102: The mobile access gateway obtains the second shared key by using the first shared key;

[0038] Sp...

Embodiment 2

[0075] This embodiment provides a method for an untrusted non-3GPP network to access a 3GPP network. When a mobile node accesses a 3GPP network through an untrusted non-3GPP network, as image 3 As shown, the method includes:

[0076] 301: During the authentication process between the mobile node and the authentication server, the evolved packet data gateway acquires the first shared key and the packet data network gateway address between the mobile node and the authentication server;

[0077] 302: The evolved packet data gateway uses the first shared key as the second shared key;

[0078] Wherein, the first shared key is Extensible Authentication Protocol-Master Session Key EAP-Master-Session-Key, and the second shared key is PMIP-KEY.

[0079] 303: The evolved packet data gateway uses the second shared key to establish a security association with the packet data network gateway corresponding to the packet data network gateway address.

[0080] The specific implementation p...

Embodiment 3

[0105] An embodiment of the present invention provides a system for accessing a 3GPP network, such as Figure 5 shown, including:

[0106] Mobile access gateway, authentication server and packet data network gateway;

[0107] The mobile access gateway includes: a first acquisition module, a second acquisition module and an establishment module;

[0108] The first obtaining module is used to obtain the packet data network gateway address and the first shared key between the mobile access gateway and the authentication server during the authentication process of the mobile node and the authentication server;

[0109] The second obtaining module is configured to use the first shared key to obtain a second shared key;

[0110] The establishment module is used to establish a security association with the packet data network gateway corresponding to the packet data network gateway address by using the second shared key.

[0111] Wherein, the first shared key is MAG-AAA KEY, and t...

Abstract

The embodiment of the invention discloses a method, a system and a gateway for accessing a 3GPP network, and belongs to the field of communication. The method comprises that: in the authentication process of a mobile node and an authentication server, a mobile access gateway acquires a packet data network gateway address, and a first shared key between the mobile access gateway and the authentication server; the mobile access gateway acquires a second shared key by utilizing the first shared key; and the mobile access gateway establishes security association by utilizing the second shared keyand a packet data network gateway corresponding to the packet data network gateway address. The system comprises the mobile access gateway, the authentication server and the packet data network gateway. The technical scheme provided by the embodiment of the invention can achieve that the mobile node securely accesses the 3GPP network through a non-3GPP network.

Description

technical field [0001] The invention relates to the communication field, in particular to a technology for a mobile node to access a 3GPP network through a non-3GPP network. Background technique [0002] The next-generation broadband wireless network is an all-IP (ALL-IP) network, which integrates various heterogeneous access networks to provide users with unified and optimal services at any time and any place. The third-generation mobile network 3GPP (Three Generation PP) network is currently developing the long-term evolution (Long Term Evolution, LTE) standard of the 3GPP evolution network. The 3GPP network can integrate the Universal Mobile Telecommunications System Terrestrial Radio Access Network (UMTS Radio Access Networks, UTRAN), Evolved Radio Access Networks (Evolved Radio Access Networks, EUTRAN) and other access networks, such as Wireless Local Area Network (WLAN) and World Interoperability for Microwave Access, WIMAX) etc. are integrated together, and various a...
