Embodiment 1
[0051] The triggering method in this embodiment is: after the UE passes the authentication, the BBF AAA triggers the BWAG to establish a GTP tunnel (Tunnel) to the PDN-GW.
[0052] After the 3GPP UE that initiates an authentication request from the BBF AAA access network is successfully authenticated by the 3GPP network, the BBF AAA obtains the subscription information and access mode of the UE from the UE authentication success response message returned by the 3GPP network.
[0053] Next, the BBF AAA sends the UE's Attach Request message to the BWAG, which carries the UE's subscription information.
[0054] In the next step, the BWAG establishes a session with the PDN gateway of the 3GPP network and establishes a tunnel; the PDN gateway provides the IP address of the UE to the BWAG.
[0055] In the next step, the BWAG replies to the BBF AAA with the UE's attach success message, which carries the UE's IP address.
[0056] In the next step, the BBF AAA sends a UE authenticatio...
Embodiment 2
[0061] This embodiment provides the specific signaling and corresponding process of the corresponding specifications of the fixed network access gateway when the RG is a routing type. For the specific process, please refer to Figure 4 , including step S401 to step S412.
[0062] Step S401, the non-BBF UE sends an authentication protocol start (EAPoL-Start) message to the RG, and performs authentication through the 802.1X protocol. UE is an 802.1X client, and RG is an 802.1X authenticator.
[0063] Step S402, after receiving the EAPoL Start message sent by the UE, the RG sends an authentication protocol ID request (EAPIdentity Request) message to the UE to notify the UE to report the user name.
[0064] Wherein, after receiving the EAP Identity Request message sent by the RG, the UE replies an authentication protocol ID response (EAPIdentity Response) message to the RG, wherein the message carries the user name.
[0065] Subsequently, the RG encapsulates the received EAP Ide...

Abstract
The present invention discloses an address allocation method and device. The method comprises: after a mobile network UE accessing from a fixed network succeeds in mobile network authentication, the fixed network access gateway receives an attachment request message sent by a fixed network AAA server, wherein , the attach request message carries the subscription information of the UE; the fixed network access gateway sends the attach request message to the mobile network gateway, and establishes a session with the mobile network gateway according to the subscription information; the fixed network access gateway receives the UE allocated by the mobile network gateway IP address, send an attach success message to the fixed network AAA server, where the attach success message carries the IP address. The invention solves the problem of how to apply the fixed network access gateway introduced into the network structure in the related art.
Description
technical field [0001] The present invention relates to the communication field, in particular to an address allocation method and device. Background technique [0002] With the development of network technology and user demand for services, terminals are gradually becoming multi-mode, and can choose to access different types of access networks to carry diverse services. Since different network connections have different characteristics and transmission capabilities, it can better meet the needs of users with multiple services. Multi-mode terminals can realize seamless connection between different types of wireless access networks, such as cellular UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) / EDGE (Enhanced Data Rate for GSM Evolution, enhanced data rate GSM (Global System for Mobile communication, global mobile communication system) evolution technology) / GPRS (General Packet Radio Service, general packet radio service technology...
