COMMUNICATION RELAY APPARATUS, COMMUNICATION SYSTEM, COMMUNICATION CONTROL METHOD AND COMPUTER READABLE MEDIUM

摘要

A protocol converting apparatus (communication relayapparatus)relayscommunicationsbetween acellular phone and an specific network (VPN) so that the cellular phone is connected to the VPN in which communication is performed by using an independently set dedicated address. The protocol converting apparatus has a data communication section that performs data communication with the cellular phone, a VPN connecting section that performs data communication with the specific network (VPN), a protocol converting section that converts a communication protocol of communication data, and an address authentication specifying section that specifies a destination of the communication data.
