A CPU of an IP telephone apparatus transmits, to an ENUM server, a message “Request the NAPTR record” corresponding to the destination terminal. The CPU also receives a message “Respond to the NAPTR information” in response to the message “Respond to the NAPTR record”. Further, the CPU automatically transmits, from a network I/F to the ENUM server, the request for the registration of information regarding the apparatus terminal when the switch is initially turned ON after the IP telephone apparatus is installed and connected to the IP network. The request for the registration is previously stored in a memory. The CPU also receives the message “Respond indicating completion of the registration” in response to the request for the registration.

A source IP telephone apparatus obtains, from an ENUM server, NAPTR records of a call destination based on a telephone number of the call destination, the telephone number being input by dialing. The source IP telephone apparatus then selects, from the obtained NAPTR records, a NAPTR record to be used for transmitting a call, based on a priority order, and transmits a call to the call destination based on an access method and a destination number included in the selected NAPTR record. When a destination IP telephone apparatus is busy, the second priority NAPTR record is selected and another call is made by automatically switching the access method.

A CPU controls the entire operation of a CA based on a control program that is stored in a memory. When receiving, for example, from an IP telephone apparatus, a request (Register) to register a NAPTR record of a terminal apparatus, the CPU searches for corresponding user data from a user database, which is described later, sends the retrieved user data to a NAPTR data converter, and stores the converted NAPTR record on an ENUM server. In addition, the CPU functions as a registration processor.

A CPU executes a process for obtaining, from an ENUM server, a NAPTR record of a destination IP terminal by controlling an IP network controller when placing a call to the destination IP terminal, a process for determining whether the destination IP terminal has at least one communication function corresponding to the source IP terminal based upon the communication functions specified in the NAPTR record and a process for displaying, on a display, the at least one communication function that is determined to be stored in the destination IP terminal.

A client, a computer-readable recording medium, and method for acquiring a uniform resource identifier are provided. The client includes a message reception unit which receives a plurality of naming authority pointer (NAPTR) records from a domain name service (DNS) server, each of the NAPTR records comprising a URI and an identifier of a user of the URI; and a URI selection unit which chooses one of the URIs respectively included in the NAPTR records by referencing the identifiers respectively included in the NAPTR records. Accordingly, it is possible to choose a URI to be used by a client from among a plurality of URIs included in URI information received from a DNS server.

The invention relates to an object naming service (ONS) architecture with decentralized management-based electronic produce code (EPC) parsing method. The EPC parsing method comprises the following steps that: firstly, a URI Conversion unit reads a company prefix in an object code and determines a country code top level domain (ccTLD) area which the object code is located at; secondly, the URI Conversion unit carries out conversion on the object code, adds the ccTLD information, and constructs a complete domain name; thirdly, an ONS resolver unit receives the converted domain name and carries out parsing according to a normal DNS query flow until a name server of the domain name returns a corresponding naming authority pointer (NAPTR) record; and fourthly, a Local System unit accesses a corresponding an EPC information server (EPC IS) or EPC discovery server (EPC DS) according to the NAPTR record so as to obtain related information of the object. According to the invention, querying time delay and expenditure of the ONS can be optimized; and privacy protection of object information by all sovereign states and areas can be guaranteed.

When a CPU receives, from a source IP telephone apparatus, a request “Register (Unregister)” for deleting a NAPTR record, or when the reception of the request “Register” for registering the NAPTR record that is regularly received from the source IP telephone apparatus is suspended, the CPU refers to the user data stored in a user database, and transmits, to an ENUM server, a request for deleting the NAPTR record of the source IP telephone apparatus. Further, when a request for the NAPTR record of the source IP telephone apparatus is regularly received from a destination IP telephone apparatus via a network interface and when the deletion process of the NAPTR record is completed, the CPU returns, to the destination IP telephone apparatus, a response indicating that the NAPTR record of the source IP telephone apparatus is deleted.

A CPU in an IP telephone apparatus automatically controls to transmit, from a network I/F to an ENUM server, a request for deleting a NAPTR record when an absent key is pressed.
