Abstract

A mobile radio station radio-communicates with a base station in accordance with a code division multiple access scheme to receive an information provision service from an information service center through the base station. The information service center supplies information data for information service, type data indicating the type of information data, and update data including version data of the information data to the base station. The mobile radio station receives the update data transmitted from the base station and displays the type data on a display, when the desired selected type data is selected from the displayed type data by user'"'"'s operation, if it is judged that the corresponding information data is the latest information data based on the version data corresponding to the selected type data, receives the information data. When the information data is the latest information data, the information service center charges an account for the reception of information data by the mobile radio station.

Claims

1. A radio communication system for radio-communicating between a base station and a plurality of mobile radio stations that communicate in accordance with a code division multiple access scheme, said system comprising:

an information service center for supplying to said base station information data including updated news information, updated weather information, and updated stock information for providing information provision service to said at least one of said plurality of mobile radio stations, type data indicating a type of said information data, and update data including version data of said information data; and

said plurality of mobile stations including means for receiving said update data transmitted from the base station and for displaying said type data, and when desired selected type data is selected from said displayed type data by a user'"'"'s operation, for judging that said corresponding information data is latest information data based on said version data corresponding to said selected type data, and for receiving said information data, wherein

said information service center charges an account for reception of said information data by said at least one of said plurality of mobile ratio stations.

2. The radio communication system according to claim 1, wherein

said at least one of said plurality of mobile radio stations updates the information data whenever the information data is received thereby and includes storage means for storing said information data, upon judging that said information data is not the latest information data, and means for reading the stored information data from said storage means for display.

3. The radio communication system according to claim 1, wherein

said information data is repeatedly transmitted to said at least one of said plurality of mobile radio stations, and when said at least one of said plurality of mobile radio stations judges that said information data is the latest data, said at least one of said plurality of mobile radio stations receives said information data being transmitted and transmits an information acquisition report including identification information to said information service center through said base station, and said information service center charges the account on a basis of said information acquisition report.

4. The radio communication system according to claim 3, wherein

said update data is transmitted using a paging channel or a dedicated code channel, and said information data is repeatedly transmitted using a dedicated code channel.

5. The radio communication system according to claim 1, wherein

said information data is not normally transmitted to said at least one of said plurality of mobile radio stations, and when said at least one of said plurality of mobile radio stations judges that said information data is the latest information data, said at least one of said plurality of mobile radio stations demands to connect to said information service center of said base station, after connecting, said information service center transmits said information data to said at least one of said plurality of mobile radio stations through said base station in response to an information transmission request including the identification information from said radio communication terminal and charges the account on a basis of said information transmission request.

6. The radio communication system according to claim 5, wherein

said update data is transmitted using a paging channel or a dedicated code channel, and said information data is transmitted using a traffic channel.

7. A method of radio communication for information provision service for radio-communicating between a plurality of mobile radio stations and an information service center, which provides an information service to the mobile radio station, through a base station in accordance with a multiple division access scheme, comprising the steps of:

supplying information data including updated news information, updated weather information, and updated stock information for providing said information provision service, type data indicating the type of the information data, and update including version data of said information data to said base station by said information service center;

receiving said update data transmitted from the base station and displaying said type data by at least one of said mobile radio stations, when desired selected type data is selected from said displayed type data by a user'"'"'s operation, and, upon judging that said corresponding information data is latest information data based on said version data corresponding to said selected type data, receiving said information data; and

charging an account by said information service center for the reception of said information data by said at least one of said plurality of mobile radio stations.

8. The method of radio communication for information provision service according to claim 7, further comprising the steps of:

updating the information data whenever information is received and storing said information data by said at least one of said Plurality of mobile radio stations, when it is judged that said information data is not the latest information data, reading the stored information data and displaying it by said at least one of said plurality of mobile radio stations.

9. The method of radio communication for information provision service according to claim 7, further comprising the steps of:

transmitting repeatedly said information data to said at least one of said mobile radio stations, when said at least one of said plurality of mobile radio stations judges that said information data is the latest information data, receiving said information data being transmitted and transmitting an information acquisition report including identification information to said information service center through said base station by said at least one of said plurality of mobile radio stations, and charging the account on a basis of said information acquisition report by said information service center.

10. The method of radio communication for information provision service according to claim 7, further comprising the following steps of:

transmitting said information data to said at least one of said plurality of mobile radio stations, when said at least one of said plurality of mobile radio stations judges that said information data is the latest information data, demanding to connect to said information service center of said base station by said at least one of said plurality of mobile radio stations, after connecting, transmitting said information data to said at least one of said plurality of mobile radio stations through said base station in response to an information transmission request including identification information from said radio communication terminal and charging the account on a basis of said information transmission request by said information service center.

11. A mobile radio station for radio-communicating with a base station in accordance with a code division multiple access scheme and receiving information data for information provision service, type data indicating a type of information data, and update data including version data of said information data from an information service center through said base station, said mobile radio station comprising:

communication means for radio-communicating with said base station;

display means for displaying at least reception information;
