With the surge of data service market opportunities, domestic operators have taken WLAN as the primary bearer for 3G data services. At present, China Telecom has proposed the strategy of “C + W ” “Internet handset ”, and China Mobile has identified “TD + WLAAN ” as the key strategy for the construction of wireless broadband networks. China Unicom has also started to use WLAN to promote solid Network broadband and mobile data services. The article expounds the current situation, level and development trend of 3G + WLAN at home and abroad, and further illustrates the purpose, function, technical level and market prospect of China Telecom’s C + W unified authentication system. Finally, combining with the author’s actual work, Wireless Gateway) C + W unified authentication system in the application and summarizes the specific implementation experience.
