  • Publication number: 20140112351
    Abstract: A communication system, for functioning without the use of dedicated lines or the Internet so as to ensure communication speed, communication quality, and communication trouble countermeasures, including a communication network and domain name server. The domain name server includes a domain name tree with a country number of a telephone number as a level 2 domain name of the domain name tree, and the domain name server receives, from a terminal, a telephone number of a destination terminal. Furthermore, based on the telephone number of the destination terminal, the domain name server (i) seeks out, in the domain name tree, an Integrated Information Communication System (ICS) user address of the destination terminal, and (ii) sends the ICS user address to the terminal, such that the communication system receives, from the terminal, the ICS user address as a destination address, and sends the ICS user frame to the destination terminal.

  • Patent number: 7516242
    Abstract: An integrated information communication system capable of improving information security is provided, in which an IP packet is detected which is sent from an external area toward either an operation management server or a relay apparatus, the detected IP packet is not entered inside the integrated information communication system in order to reduce such a chance that the operation management server and the relay apparatus are unfairly attacked. Also, such an IP packet is detected and discarded, which violates an address application rule established so as to keep secret of a communication company network. An address which is applied to either an operation management server or a relay apparatus employed in the integrated information communication system is sectioned, or classified as an “address which is not opened outside network” with respect to an external area of the communication system. A packet filter is installed in an address control apparatus.
