First Claim
1. A communication system comprising:
- a data center with a wide area network being interposed between the data center and a wireless LAN (Local Area Network) to which a terminal connects to, wherein the data center comprises;
a VPN apparatus that connects with the terminal using a VPN (Virtual Private Network) through the wide area network and the wireless LAN; and
a virtual core network virtualizing at least a part of constituent elements of a core network, wherein the VPN apparatus is connected to the virtual core network,wherein the terminal communicates with a connection destination, from the VPN via the VPN apparatus, via the virtual core network, and further via a packet data network to which the virtual core network connects.
