SIMULTANEOUS SERVICE PROVIDING SYSTEM BETWEEN HETEROGENEOUS NETWORKS

摘要

PURPOSE: A simultaneous service providing system for heterogeneous networks is provided to set a packet data network-gateway (P-GW) as a final terminal of signal transmission and implement seamless wireless local area network (WLAN) offloading. CONSTITUTION: An evolved packet data gateway (ePDG) (10) is linked with a first wireless network. A serving gateway (S-GW) (15) and a P-GW (20) are linked with a second wireless network. Multiple first access point (AP) parts (30) transmit and receive signals of the first wireless network to and from a mobile communications terminal. Multiple second AP parts (40) transmit and receive signals of the second wireless network to and from the mobile communications terminal. The P-GW includes a flow-based deep packet inspection (DPI) module part.
