Abstract

The present invention provides an information processing terminal device that is adapted to define a response waiting time before timeout. The information processing terminal device includes a communication section transmitting data to and receiving data from an information providing apparatus, a timing section timing the duration from the time of transmitting data from the communication section to the time of receiving a response from the information providing apparatus made to the transmitted data, and a communication controller defining a response waiting time for the information providing apparatus as a function of the duration timed by the timing section and deciding whether a communication is available between the communication section and the information providing apparatus by referring to the defined response waiting time.

Claims

1. An information processing terminal device comprising:

communication means for transmitting data to and receiving data from an information providing apparatus;

timing means for timing a duration from a time of transmitting data from the communication means to a time of receiving a response from the information providing apparatus made in response to the transmitted data; and

communication control means for defining a response waiting time for the information providing apparatus as a function of the duration timed by the timing means and for deciding whether a communication is available between the communication means and the information providing apparatus by referring to the defined response waiting time.

2. The terminal device according to claim 1, wherein the communication means is adapted to transmit data to and receive data from each of a plurality of information providing apparatuses and the communication control means is adapted to define a response waiting time for each of the information providing apparatuses according to the duration timed by the timing means and to decide whether a communication is available for each of the information providing apparatuses by referring to the defined response waiting time.

3. The terminal device according to claim 1, further comprising:

memory means for storing the response waiting time defined by the communication control means; and

the communication control means being adapted to store identifying information for identifying a previously communicated with information providing apparatus with a corresponding response waiting time in the memory means so as to decide whether a communication is available by referring to the response waiting time stored in the memory means.

4. The terminal device according to claim 1, wherein the communication control means is adapted to update the response waiting time according to the duration timed by the timing means each time it is connected to the information providing apparatus and to decide whether a communication is available for the information providing apparatus by referring to the updated response waiting time.

5. The terminal device according to claim 1, wherein the communication control means is adapted to define the response waiting time according to a shortest response time in a plurality of times of communication with the information providing apparatus and to decide whether a communication is available for the information providing apparatus by referring to the defined response waiting time.

6. The terminal device according to claim 1, wherein the communication control means is adapted to define the response waiting time according to an average value of response waiting times of a plurality of times of communication with the information providing apparatus and to decide whether a communication is available for the information providing apparatus by referring to the defined response waiting time.

7. The terminal device according to claim 1, wherein the communication control means is adapted to define the response waiting time according to a standard deviation of response waiting times of a plurality of times of communication with the information providing apparatus and to decide whether a communication is available for the information providing apparatus by referring to the defined response waiting time.

8. A communication system connecting an information providing apparatus and an information processing terminal device, wherein the information processing terminal device comprises:

communication means for transmitting data to and receiving data from the information providing apparatus;

timing means for timing a duration from a time of transmitting data from the communication means to a time of receiving a response from the information providing apparatus made in response to the transmitted data; and

communication control means for defining a response waiting time for the information providing apparatus as a function of the duration timed by the timing means and for deciding whether a communication is available between the communication means and the information providing apparatus by referring to the defined response waiting time.

9. A communication method to be used for an information providing apparatus and an information processing terminal device for mutual communications, the method comprising:

a transmitting step of transmitting data from the information processing terminal device;

a timing step of timing a duration from a time of transmitting data in the transmitting step to a time of receiving a response from the information providing apparatus made in response to the transmitted data; and

a communication control step of defining a response waiting time for the information providing apparatus as a function of the duration timed in the timing step and for deciding whether a communication is available with the information providing apparatus by referring to the defined response waiting time.

10. An information processing terminal device comprising:

a communication section transmitting data to and receiving data from an information providing apparatus;

a timing section timing a duration from a time of transmitting data from the communication section to a time of receiving a response from the information providing apparatus made in response to the transmitted data; and

a communication controller defining a response waiting time for the information providing apparatus as a function of the duration timed by the timing section and for deciding whether a communication is available between the communication section and the information providing apparatus by referring to the defined response waiting time.

11. A communication system connecting an information providing apparatus and an information processing terminal device, wherein the information processing terminal device comprises:

a communication section transmitting data to and receiving data from the information providing apparatus;

a timing section timing a duration from a time of transmitting data from the communication section to a time of receiving a response from the information providing apparatus made in response to the transmitted data; and

a communication controller defining a response waiting time for the information providing apparatus as a function of the duration timed by the timing section and for deciding whether a communication is available between the communication section and the information providing apparatus by referring to the defined response waiting time.
