Abstract

A communication terminal includes: a communication unit; a memory; a first obtaining unit for obtaining first data; and a first control unit for detecting, using the communication unit, whether the communication terminal is in a first state in which the communication terminal can exchange the first data with another terminal or in a second state in which the communication terminal cannot exchange the first data with another terminal, thereby storing a part of the first data obtained during the second state in the memory as second data, and for transmitting the second data to another terminal when a transition from the second state to the first state occurs.

Claims

1. A network system comprising at least a first terminal and a second terminal,

said first terminal including:

a first communication unit;

a memory;

a first obtaining unit for obtaining first data; and

a first control unit for detecting, using said first communication unit, whether said first terminal is in a first state in which said first terminal can exchange said first data with said second terminal or in a second state in which said first terminal cannot exchange said first data with said second terminal, thereby storing a part of said first data obtained during said second state in said memory as second data, and for transmitting said second data to said second terminal when a transition from said second state to said first state occurs,

said second terminal including;

a display;

a second communication unit;

a second control unit for sequentially receiving said first data from said first terminal using said second communication unit during said first state, and receiving said second data from said first terminal when the transition from said second state to said first state occurs; and

a display control unit for causing said display to sequentially display said first data and said second data.

2. The network system according to claim 1, wherein

said second terminal further includes a second obtaining unit for obtaining location information of said second terminal,

said first obtaining unit obtains location information of said first terminal as said first data, and

said display control unit causes said display to display locations of said first terminal and said second terminal based on the location information of said first terminal and said second terminal.

3. A communication terminal connectable to another terminal through a network, comprising:

a communication unit;

a memory;

a first obtaining unit for obtaining first data; and

a control unit for detecting, using said communication unit, whether said communication terminal is in a first state in which said communication terminal can exchange said first data with said another terminal or in a second state in which said communication terminal cannot exchange said first data with said another terminal, thereby storing a part of said first data obtained during said second state in said memory as second data, and for transmitting said second data to said another terminal when a transition from said second state to said first state occurs.

4. A communication terminal connectable to another terminal through a network, comprising:

a display;

a communication unit;

a communication control unit for sequentially receiving said first data from said another terminal using said communication unit during a first state in which said another terminal can exchange first data with said communication terminal, and receiving second data from said another terminal when a transition from a second state in which said another terminal cannot exchange said first data with said communication terminal to said first state occurs; and

a display control unit for causing said display to display said first data and said second data.

5. A communication method in a network system comprising at least a first terminal and a second terminal, comprising the steps of:

obtaining, by said first terminal, first data;

detecting, by said first terminal, whether said first terminal is in a first state in which said first terminal can exchange said first data with said second terminal or in a second state in which said first terminal cannot exchange said first data with said second terminal, thereby storing a part of said first data obtained during said second state in a memory as second data;

sequentially transmitting, by said first terminal, said first data to said second terminal during said first state;

sequentially receiving, by said second terminal, said first data from said first terminal during said first state;

transmitting, by said first terminal, said second data to said second terminal when a transition from said second state to said first state occurs;

receiving, by said second terminal, said second data from said first terminal when the transition from said second state to said first state occurs; and

causing, by said second terminal, a display to sequentially display said first data and said second data.

6. A communication method for a communication terminal connectable to another terminal through a network, the communication terminal including a communication unit, a processor and a memory, the communication method comprising the steps of:

obtaining, by said processor, first data;

detecting, by said processor, whether said communication terminal is in a first state in which said communication terminal can exchange said first data with said another terminal or in a second state in which said communication terminal cannot exchange said first data with said another terminal, using said communication unit, thereby storing a part of said first data obtained during said second state in said memory as second data; and

transmitting, by said processor, said second data to said another terminal using said communication unit when a transition from said second state to said first state occurs.

7. A communication method for a communication terminal connectable to another terminal through a network, the communication terminal including a communication unit, a processor and a display, the communication method comprising the steps of:

sequentially receiving, by said processor, first data from said another terminal using said communication unit during a first state in which said another terminal can exchange said first data with said communication terminal;

receiving, by said processor, second data from said another terminal using said communication unit when a transition from a second state in which said another terminal cannot exchange said first data with said communication terminal to said first state occurs; and

causing, by said processor, said display to sequentially display said first data and said second data.

8. A communication program for allowing communication of a communication terminal connectable to another terminal through a network, the communication terminal including a communication unit, a processor and a memory,

said communication program causing said processor to perform the steps of:

obtaining first data;

detecting, using said communication unit, whether said communication terminal is in a first state in which said communication terminal can exchange said first data with said another terminal or in a second state in which said communication terminal cannot exchange said first data with said another terminal, thereby storing a part of said first data obtained during said second state in said memory as second data; and

transmitting said second data to said another terminal using said communication unit when a transition from said second state to said first state occurs.

9. A communication program for allowing communication of a communication terminal connectable to another terminal through a network, the communication terminal including a communication unit, a processor and a display,

said communication program causing said processor to perform the steps of:

sequentially receiving said first data from said another terminal using said communication unit during a first state in which said another terminal can exchange first data with said communication terminal;

receiving second data from said another terminal using said communication unit when a transition from a second state in which said another terminal cannot exchange said first data with said communication terminal to said first state occurs; and

causing said display to sequentially display said first data and said second data.
