Embodiment 1

[0038] see image 3 , the embodiment of the present invention provides a method for controlling access. In this embodiment, the terminal is in a non-roaming state and accesses a 3GPP network from a trusted non-3GPP (such as CDMA) network and is returned after being judged by the AAA server The address of the PDN GW is used as an example for illustration, and the specific steps are as follows:

[0039] Step 101: The terminal accesses a trusted non-3GPP network—CDMA network.

[0040] Step 102: The access gateway PDSN of the CDMA network sends an access request message to the AAA server to perform authentication for accessing the 3GPP network, and carries the identification of the terminal and the multi-mode capability information of the terminal in the access request message.

[0041] Wherein, the AAA server may be an AAA server in a CDMA network, may also be an AAA server in a 3GPP network, or may be an AAA server common to both a CDMA network and a 3GPP network.

[0042] The...

Embodiment 2

[0054] see Figure 5 , the embodiment of the present invention also provides a method for controlling access. In this embodiment, the terminal is in the non-roaming state and accesses the 3GPP network from a trusted non-3GPP (such as CDMA) network and the non-3GPP network The access gateway determines whether it needs to obtain the address of the PDN GW as an example, and the specific steps are as follows:

[0055] Step 201: The terminal accesses a trusted non-3GPP network—CDMA network.

[0056] Step 202: The access gateway PDSN of the CDMA network sends an access request message to the AAA server to perform authentication for accessing the 3GPP network. The access request message carries the identifier of the terminal, and further, it may also carry the multi-mode capability of the terminal information.

[0057] Wherein, the AAA server may be an AAA server in a CDMA network, may also be an AAA server in a 3GPP network, or may be an AAA server common to both a CDMA network a...

Embodiment 3

[0066] see Image 6 , the embodiment of the present invention also provides a method for controlling access. In this embodiment, the terminal is in a roaming state and accesses a 3GPP network from a trusted non-3GPP (such as CDMA) network, and the AAA server returns after judging The address of the PDN GW is used as an example for illustration, and the specific steps are as follows:

[0067] Step 301: The terminal accesses a trusted non-3GPP network—CDMA network, and the terminal is located in the roaming area of ​​the CDMA network at this time.

[0068] Step 302: the access gateway PDSN of the CDMA network sends an access request message to the VAAA (Visit AAA, visit AAA) server in the roaming area, performs authentication for accessing the 3GPP network, and carries the terminal identifier in the access request message and the multimode capability information of the terminal.

[0069] Step 303: After receiving the access request message, the VAAA server forwards the access ...

Abstract

The invention discloses a method for controlling access, an access gateway and an authentication server which belongs to the communications technology field. The method includes steps as follows: when a terminal accesses 3GPP network from non-3GPP network, judging the terminal whether having multi-module ability and switching ability for signed up various type network, and the network type corresponding to the multi-module ability includes at two network types corresponding to one switching ability of the switching ability; if yes, the access gateway in non 3GPP network obtains PDN GW address; if no, no-obtain PDN GW address. The access gateway includes a sending module and a receiving module. The authentication server includes a receiving module and a sending module. The method can realize that the terminal probable occurring network switch is anchored on PDN GW, the terminal no-probable occurring network switch is not anchored when the terminal accesses 3GPP network from non 3GPP for avoiding unnecessary burthen to PDN GW.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for controlling access, an access gateway and an authentication server. Background technique [0002] In order to increase the competitiveness of future mobile networks, 3GPP (the 3rd Generation Project Partnership, Third Generation Partnership Project) is studying a future network architecture, which includes SAE (System Architecture Evolution, System Architecture Evolution) and LTE (Long Term Evolution, long-term evolution of the access network), wherein the evolved access network is called E-UTRAN (Evolved UMTS Territorial Radio Access Network, evolved UMTS Terrestrial Radio Access Network). The SAE network will be able to support the access of multiple non-3GPP (non-3GPP) wireless access networks. The common non-3GPP wireless access networks include: 3GPP2 or CDMA (Code Division Multiple Access) network , 802.16 is WiMAX (Worldwide Interoperability for Microw...
