Latest Patents

Chao-Ching Wu holds a patent for a "Vertical handoff method and system in WLAN/3G integrated networks." This invention involves establishing an IPSec tunnel by assigning parameters TS and SPI, which are translated into TFT (PF I, PF II). A first index is assigned, and a GTP tunnel is created based on TFT (PF I, PF II) and the first index. The GGSN generates a table based on these parameters for user equipment (UE) in the WLAN network to access 3G services. When roaming into the 3G network, the UE assigns a second index, allowing for the establishment of a tunnel between the SGSN and UE based on the second index. This innovative approach ensures that 3G services remain uninterrupted for users.
