Abstract

A communication terminal device has a storage portion, in which the information retrieved by a base unit is stored so that, when a piece of information of which the retrieval is requested on a remote unit is stored in the storage portion, that piece of information is read out from the storage portion. Moreover, in the storage portion is stored also the information retrieved by the remote unit so that, when a piece of information of which the retrieval is requested on the base unit is stored in the storage portion, that piece of information is read out from the storage portion. This permits the information retrieved via the Internet by either of the base and remote units to be shared between them.

Claims

1. A communication terminal device comprising:

a base unit connected to a server by way of a communication network;

at least one remote unit connected to the base unit; and

a storage portion for storing information retrieved by the base unit,

wherein the base and remote units are each capable of retrieving information from outside the communication terminal device, and, when a piece of information of which retrieval is requested on the remote unit is stored in the storage portion, said piece of information is read out from the storage portion.

2. A communication terminal device as claimed in claim 1,

wherein, when a piece of information is read out from the storage portion, an indication is given saying that said piece of information is from already retrieved information.

3. A communication terminal device as claimed in claim 1,

wherein, when a piece of information is read out from the storage portion, an inquiry is made asking whether to use said piece of information or not.

4. A communication terminal device as claimed in claim 1,

wherein reading-out of information from the storage portion can be restricted.

5. A communication terminal device as claimed in claim 1,

wherein the remote unit can connect directly to the communication network independently of the base unit.

6. A communication terminal device as claimed in claim 1,

wherein only URLs pointing to locations of information are stored in the storage portion.

7. A communication terminal device as claimed in claim 1,

wherein the storage portion is incorporated in the base unit.

8. A communication terminal device comprising:

a base unit connected to a server by way of a communication network;

at least one remote unit connected to the base unit; and

a storage portion for storing information retrieved by the remote unit,

wherein the base and remote units are each capable of retrieving information from outside the communication terminal device, and, when a piece of information of which retrieval is requested on the base unit is stored in the storage portion, said piece of information is read out from the storage portion.

9. A communication terminal device as claimed in claim 8,

wherein, when a piece of information is read out from the storage portion, an indication is given saying that said piece of information is from already retrieved information.

10. A communication terminal device as claimed in claim 8,

wherein, when a piece of information is read out from the storage portion, an inquiry is made asking whether to use said piece of information or not.

11. A communication terminal device as claimed in claim 8,

wherein reading-out of information from the storage portion can be restricted.

12. A communication terminal device as claimed in claim 8,

wherein the remote unit can connect directly to the communication network independently of the base unit.

13. A communication terminal device as claimed in claim 8,

wherein only URLs pointing to locations of information are stored in the storage portion.

14. A communication terminal device as claimed in claim 8,

wherein the storage portion is incorporated in the base unit.
