| Abstract: | Direct Tunnel is a innovative network optimization technology based on the traditional 3G network architecture, SGSN establishes the direct data access from RNC to GGSN, user data directly transmit in direct tunnel but SGSN and flatten the user palnc network structure. It can be deployed in WCMA and TD-SCDMA networks to enhance the benefits of network investment, improve the network extensibility and reduce network OPEX. Direct Tunnel technology takes the first step to achieve the smooth evolution for LET. |
