Authentication notifying method and system

Abstract

The invention discloses an authentication notifying method, which comprises the following steps that a BBF (broadband forum) authentication, authorization and accounting (AAA) unit sends the MAC (medium access control) address of UE (user equipment) to broadband network gateway (BNG) control equipment when the UE is accessed to a BBF access network and further passes authentication; or when the UE is accessed to the BBF access network and requests an IP (internet protocol) address, the BNG control equipment checks whether the UE passes the authentication or not, and when the BNG control equipment determines that the authentication information of the UE does not exist, the authentication information of the UE is acquired from the AAA unit; or when the UE is accessed to the BFF access network and requests the IP address, a residence gateway (RG) checks whether the UE passes the authentication or not, and when the UE is determined to pass the authentication, the RG notifies the BNG control equipment that the UE passes the authentication. The invention also provides an authentication notifying system. According to the technical scheme disclosed by the invention, the BNG control equipment can know whether the UE requesting to access passes the authentication or not in time.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an authentication notification method and system. 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. Different network connections have different characteristics and transmission capabilities, so as to better meet the diverse needs of users for services. At present, multi-mode terminals can realize seamless connection between different types of wireless access networks, such as cellular Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System), Enhanced Data Rate GSM Evolution Technology (EDGE, Enhanced Data Rate for GSM Evolution), general packet radio service technology (GPRS, General Packet Radio Service) and IEEE 802.11 in the wireless local area network (...

AI Technical Summary

Problems solved by technology

[0007] The existing technology has the following defects: during the authentication process, the UE sends the authentication message to the RG, and after the RG encapsulates it, the authentication message is sent to the AAA to complete the authentication of the UE (that is, the authentication passes figure 2 In this way, without going through BNG); however, in the address allocation stage, the DHCP server assigns the IP address to the user. In this case, since the BNG does not know whether the UE has passed the authentication, it cannot trigger the DHCP server to assign the IP address to the UE. IP address
