Problems solved by technology

Both LNS and GGSN can only control data at the IP layer, and cannot control functions above the IP layer, and cannot realize more complex network functions
[0004] As a result, the place of origin can only charge for international roaming data according to the duration and traffic

Abstract

The invention discloses a mobile data international roaming user access method and a network device, relating to the technical field of mobile Internet international roaming. The method comprises the steps of: establishing a first protocol tunnel between an agent conversion gateway serving as a tunnel protocol agent and an international roaming user visiting place; obtaining access permission of the international roaming user from an attributive place AAA (Authentication, Authorization and Accounting) by the agent conversion gateway; and establishing a second protocol tunnel between the agent conversion gateway and the attributive place access gateway of the international roaming user. The agent conversion gateway is added in the international roaming network, and the agent conversion gateway can provide agent services and conversion service for accessing to the network of the attributive place for the user based on the authorization result and application need of the user, so that the attributive place access gateway in the CDMA (Code Division Multiple Access) international roaming can perform data roaming control on the user, has the DPI (Deep Packet Inspection) capability, and can perform control and analysis of more than three layers of the network on an IP (Internet Protocol) packet.

Description

technical field [0001] The invention relates to the technical field of mobile Internet international roaming, in particular to a mobile data international roaming user access method and network equipment. Background technique [0002] At present, when CDMA (Code Division Multiple Access, Code Division Multiple Access) users, including CDMA dual-mode users, perform international data roaming, the home network can only perform IP (Internet Protocol, a protocol for interconnection between networks)) packets. Simple control and analysis below layer 3, implementing extensive management, does not have DPI (Deep Packet Inspection, deep packet inspection technology) capability. [0003] Such as figure 1 As shown, the data international roaming user 10, through the LAC (L2TP Access Concentrator, L2TP Access Concentrator) 131 of the visited PDSN (Packet Data Serving Node, packet data service node) 13 of the visited CDMA network, through the VPN (Virtual Private Network , Virtual Pri...
