H3C ICG Gateway 3G Wireless Access Solution

I. Overview With the distribution of 3G licenses in China and the maturity of commercial 3G networks, users have become more and more strong for 3G wireless applications, because 3G networks bring great convenience to users, and they are right Wired communication methods and improve network reliability are very good. As a leading manufacturer in the field of global network communications, H3C is also in front of supporting wireless 3G communications. At present, its ICG series communication gateway supports complete 3G communication capabilities, including three types of WCDMA, CDMA2000, and TD-SCDMA, support The interface morphology and equipment model are also very rich. The 3G access solution based on the ICG gateway means that the ICG communication gateway provides uplink 3G wireless communication by an external 3G-MODEM (USB interface type) or 3G wireless interface card module to provide a communication application as a backup or supplement as a wired communication link. Way. The main features and advantages of this wireless communication scheme are: The bandwidth of 3G wireless communications has been greatly improved, and the availability has greatly enhanced, and favorable conditions for its popularity and promotion applications; 3G wireless communication is well satisfied with communication needs that are inconvenient to obtain a wired link resource or a mobile communication application scenario, enhance communication adaptability of communication gateway devices; 3G wireless communication coverage network is a public network environment, using gateway equipment powerful network security and data encryption capabilities, fully demonstrate security hazards for wireless communication applications; The 3G wireless communication interface is packaged on the gateway is a standard IP interface, which does not have any functions and business differences with other wired interfaces, which guarantees 3G wireless communication. Second, ICG Enterprise Gateway 3G Typical Applications and Network 2.1 3G wireless interface applied to VPDN networking The H3C ICG gateway serves as a LC device of the L2TP client, the gateway device of the operator, as the LAC device of the L2TP tunnel, the entry of the enterprise center as the LNS device of the L2TP tunnel, the 3G gateway of the enterprise outlets Connect to the operator's LAC device through 3G Wi-Fi The company's LNS device is generally connected to the operator's LAC device through a wired line.
