Home gateway apparatus
First Claim
1. A gateway apparatus that connects to a domain name system (DNS) server and a terminal apparatus via a network, and connects to a plurality of internal terminals via an internal network, the gateway apparatus comprising:
- a memory that stores internal naming authority pointer record (NAPTR) records for the plurality of internal terminals, each of the internal NAPTR records comprising a service field and a uniform resource identifier (URI) scheme for an internal terminal, a subset of the internal NAPTR records comprising external NAPTR records, the external NAPTR records being internal NAPTR records which do not include private terminal information; and
a transmitter that transmits only the external NAPTR records in the memory to the DNS server to enable the DNS server to store and manage the external NAPTR records.

Abstract
A home gateway apparatus is connected to a DNS server that stores and manages telephone numbers and an external NAPTR record corresponding to each telephone number. The home gateway apparatus also includes and mutually connects a plurality of internal terminals. The home gateway apparatus includes an NAPTR record generator that generates an internal NAPTR record of all internal terminals; an internal NAPTR memory area that stores the generated internal NAPTR record; an external NAPTR memory area that stores an external NAPTR record, which is selected from the internal NAPTR record to be allowed to be disclosed to the DNS server; and a self NAPTR record notification unit that notifies the DNS server of the external NAPTR record so that the DNS server can register the external NAPTR record in association with a telephone number.

8. A method of providing management information for a plurality of internal terminals connected to a gateway apparatus to a domain name system (DNS) server, the method comprising:
-
storing internal naming authority pointer record (NAPTR) records for each of the plurality of internal terminals in the gateway apparatus, each of the internal NAPTR records comprising a service field and a uniform resource identifier (URI) scheme for an internal terminal, a subset of the internal NAPTR records comprising external NAPTR records, the external NAPTR records being internal NAPTR records which do not include private terminal information; and transmitting only the external NAPTR records stored in the gateway apparatus from the gateway apparatus to the DNS server to enable the DNS server to store and manage the external NAPTR records. - View Dependent Claims (9, 10, 11, 12, 13, 14)
