Abstract

If an information sending request is received from an information terminal via a data communication connection before search for information requested by the information terminal via a voice communication connection is finished, the sending of the information to the information terminal is prohibited. This prevents old information from being transmitted to the information terminal in response to the information sending request.

wherein the processor is further operable to;

query if data is stored in the first memory after receipt of the information sending request from the information terminal; and

if the data is stored in the first memory, the processor is further operable to;

move the requested information stored in the first memory to the second memory, the data being the requested information; and

allow transmission of the requested information from the second memory to the remote information terminal.

6. The apparatus according to claim 5 wherein the processor is further operable to:

prohibit transmission to the remote information terminal using the at least one communication path when a response to the query is that no data is stored in the first memory after receipt of the information sending request from the remote information terminal.

7. The apparatus according to claim 5 wherein the processor is further operable to:

permit transmission of the requested information from the second memory to the remote information terminal using the at least one communication path in response to an information resending request even if a response to the query is that no data is stored in the first memory.

8. The apparatus according to claim 1 wherein the processor is further operable to:

permit transmission of only a part of the requested information in response to receipt of an information resending request wherein the part of the requested information failed to be sent to the remote information terminal in response to a prior information sending request.

9. The apparatus according to claim 1 wherein the at least one communication path includes:

a communication unit;

a voice communication connection, wherein the communication unit is configured to receive requests for the requested information from the remote information terminal via the voice communication connection; and

a data communication connection, wherein the communication unit is configured to receive the information sending request from the remote information terminal via the data communication connection.

10. An information providing apparatus, comprising:

information search means for searching for information based on a request from a remote information terminal via a voice communication connection;

first storage means for storing the requested information found by the information search means;

control means for prohibiting transmission of any data to the remote information terminal if an information sending request is received from the remote information terminal via a data communication connection before the requested information found by the information search means is stored in the first storage means after receiving the request from the remote information terminal via the voice communication connection.

11. An information providing apparatus, comprising:

a storage device;

a communication path for sending data stored in the storage device to a remote information terminal; and

a processor operable to;

search for information requested from an information terminal via a voice communication connection;

receive an information sending request from the information terminal via the communication path; and

permit transmission of the data stored in the storage device to the remote information terminal over the communication path in response to the information sending request when the information sending request is received before the search for the information requested and when the information requested is found and is stored in the storage device as the data.

12. An information providing system, comprising:

an information terminal; and

an information providing apparatus including a voice communication connection and a data communication connection established by the information terminal, the information providing apparatus including;

a storage device; and

a processor operable to;

search for information requested from the information terminal via the voice communication connection;

store the information requested that is found as a result of the search in the storage device;

receive an information sending request from the information terminal via the data communication connection; and

prohibit transmission of data from the storage device to the information terminal if the information sending request is received before the information requested that is found as the result of the search is stored in the storage device; and

wherein the information terminal includes;

a display device for displaying the information requested that is received from the information providing apparatus.

13. An information providing method for an information center, comprising:

prohibiting transmission of data from the information center to a remote information terminal if an information sending request is received from the remote information terminal via a data communication connection to the information center before a search for information requested from the remote information terminal via a voice communication connection to the information center is finished.

14. The method according to claim 13, further comprising:

searching for the information requested from the remote information terminal via the voice communication connection; and

storing the information requested in a first memory of the information center; and

wherein the search for the information requested from the information terminal is finished when the information requested is stored in a first memory.

15. The method according to claim 13, further comprising:

permitting transmission of data from the information center when the search for the information requested from the remote information terminal is finished; and

prohibiting the transmission of data from the information center to a remote information terminal again after the information requested is sent to the remote information terminal.

16. The method according to claim 13, further comprising:

generating an index for permitting or prohibiting the transmission of data to the remote information terminal;

using the index for determining whether to permit or prohibit the transmission of data to the remote information terminal based on a state of the index and in response to receipt of the information sending request from the remote information terminal.

17. The method according to claim 16, further comprising:

permitting transmission of the information requested to the remote information terminal, regardless of the state of the index, if an information resending request is received from the remote information terminal.
