| With the development of network technology and communication technology, forms of network access vary from the original telephone dial-up to ADSL and wireless access (WIFI、WCDMA、CDMA2000、 TDSCDMA). Especially with a wide range of access mode signal coverage and fast Internet access,3G is of huge potential for future development. The rapid development of3G mobile communication and mobile Internet technology, together with the growing popularity of mobile Internet, mobile office and mobile payment application requirements continuously improve people’s needs for the quality of the network, real-time Internet access and network security. As mobile Internet applications,3G network represented by wcdma, cdma2000and tdscdma meet the needs of real-time mobile Internet access.3G is a form of access to the Internet with rapid development and wide usage in mobile access technology. Although won praise from corporate users and individual users for its portable equipment, a wide network coverage and low cost,3G mobile access is of defects due to single signal instability as well as low3G access network bandwidth. Based on gateway design under linux system and key technologies of multi-link3G signal access, this thesis focuses on implementing Policy Routing、Load balancing、Bandwidth control、Firewall、other technologies required by3G smart gateway. In addition, a3G smart access gateway system is designed and implemented with related testing laboratories verification.The main researches of the thesis are as follows:1. In-depth analysis and research on related technologies to3G smart integrated access gateway design; 2. Design and implementation of a3G smart access gateway system. Details from system design, key technologies, system performance and other aspects of the system are presented, and verification of the test results is given.3. Network monitoring capabilities for3G smart integrated access gateway system expansion study and propose a better design of the function expansion. |
