If it is determined that the data transmission has been successful, the portable terminal 120 displays the success of the processing on the communication information display unit 207 (S520), and if it is determined that the data transmission has failed, The mobile terminal 120 has lost processing Loss is displayed on the communication information display section 207 (S518). In any case, the mobile terminal 120 continues to connect with the external terminal 701 (S522).
- the fax 115 receives the data transmission instruction transmitted from the mobile terminal 120 by the signaling control unit 407 (S 532), the fax 115 determines whether or not the received data transmission instruction can be processed by the overall control unit. Determined by 406. As a result, if it is determined that the processing cannot be performed, the FAX 115 transmits a response indicating that the processing cannot be performed to the portable terminal 120 (S546), and transitions to the initial state (S548).
- the fax 115 transmits data in accordance with the data transmission instruction (S536). Specifically, the fax 15 analyzes the user's request, acquires the data transmitted by the data input / output unit 408 (S538), and can process the acquired data by the data processing unit 405. Convert to data (S540). Subsequently, the fax 115 is transmitted to the external terminal 701 by the signaling control unit 407 (S542). After transmitting the data, the FAX 115 transmits a processing completion response to the portable terminal 120 (S544), and transitions to the initial state (S546).
- the FAX 115 when transmitting data that cannot be processed by the mobile terminal 120 to another terminal, the FAX 115 processes the data, and the data is transmitted from the FAX 115. can do.
- devices displayed as data-processable devices are devices recorded on the usable device information recording medium 207, so that the selected device can be used by the user. It has been confirmed in advance that there is no need to perform such confirmation every time a device is selected, so connection delay can be reduced.
- the network server, the mobile terminal, the network system including the same, and the communication method using the same according to the present invention have been described in detail with the embodiments.
- the present invention is not limited to the embodiments. .
- the communication method for communicating with the external terminal 701 outside the oral IP network 111 has been mainly described.
- the present invention does not include the oral IP network which does not include the communication with the external terminal 701. Applicable to communication within network 111 only can do.
- the available devices are displayed, the user is allowed to select a desired printer, and the selected printer is selected.
- a communication method of transmitting a print processing request in the evening is also included in the present invention. That is, by displaying and selecting an available device based on the information recorded on the available device recording medium 207, a sequence for confirming whether or not the device can be used becomes unnecessary, and connection time delay Can be reduced.
- the mobile terminal since the network management device transmits the device information in response to the registration request, the mobile terminal can acquire the information on the devices that can be used at the first stage of registration in the network. Yes, and because the registration response includes the device information, the mobile terminal has an excellent effect that the device information can be acquired in a simple sequence of the registration request and the response: connected to the network
- the present invention is useful as a network management device for managing terminals, a mobile terminal connected to this network, and a network system, and a communication method using the same.
