Abstract

PROBLEM TO BE SOLVED: To provide teletext information of the same content to all communication terminal equipments receiving a signal from a PDC base station at the same time by converting information into the teletext information and allowing the base station to send teletext information data to the communication terminal equipments. SOLUTION: When a reception circuit 10a receives a radio signal, a logic section 11 discriminates whether or not teletext information data are included in the signal, and storage processing of the teletext information data is finished when the teletext information data are not included and the teletext information data are extracted from the radio signal and stored in a memory 11b when the teletext information data are included. The memory 11b stores the teletext information data as above by each item through classification and the user confirms each teletext information items displayed on a display section 12 and the item number of the teletext information data desired to be extracted is entered from an operation section 13. As a result, a CPU 11a makes an extract request of individual information data to be designated to the memory 11b.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a character information distribution system and a communication terminal according to the present invention will be described with reference to FIGS.

First, the overall configuration of the character information distribution system of the present embodiment will be described with reference to FIG. The National Police Agency 1 or the Japan Highway Public Corporation 2 is an information source of text information that provides traffic information, and the Meteorological Agency 3 is an information source of text information that provides a weather forecast. Here, only the traffic information and the weather forecast are shown as items of the character information, but other various information (life-based information) closely related to life provided by various government agencies are items of the character information.

The character information from each of these information sources is transmitted to the information collecting center 4 (information collecting means) in a centralized manner. The information collection center 4 converts data from these information sources into a format that can be distributed as character information in an existing PDC system,
It transmits to each PDC base station 5 which comprises C system. When the character information data is received from the information collection center 4, each PDC base station 5 distributes the data to each of the PDC portable mobile terminals 6A, 6B, 6C,... (Communication terminal) in real time.

For example, National Police Agency 1 or Japan Highway Public Corporation 2
, Traffic information that changes momentarily is transmitted to the information collection center 4. When the traffic information is received, the information collection center 4 immediately transmits the traffic information to each of the PDC base stations 5, and transmits the traffic information to each of the PDC base stations 5. 5 immediately transmits the received traffic information to each of the PDC portable mobile terminals 6A, 6B, 6C,.
Deliver to.

Next, a functional configuration of the PDC portable mobile terminal (communication terminal) according to the present embodiment will be described with reference to FIG. In this figure, reference numeral 10 denotes a radio unit, which communicates with the PDC base station 5 constituting the PDC system. The radio unit 10 includes a receiving circuit 10a
The radio signal transmitted from the PDC base station 5 to the PDC portable mobile terminal is taken into the receiving circuit 10a and demodulated.

Reference numeral 11 denotes a logic unit,
a, a memory 11b, and a power supply unit 11c. The CPU 11a controls the operation of the PDC portable mobile terminal according to a control program stored in the memory 11b. The CPU 11a includes a receiving circuit 10a
Analyzes control data and character information data included in the radio signal received in step (1), generates control data for transmitting necessary information to the PDC base station 5, and transmits a radio signal to the radio unit 10. Make requests, etc.

The memory 11b stores the control program and also stores and accumulates the character information signal taken into the receiving circuit 10a. The power supply unit 11c includes a CPU 11
Power is supplied to each part of the PDC mobile terminal under the control of a.

Reference numeral 12 denotes a display unit, which displays various information related to the communication with the base station and displays character information based on the character information signal. An operation unit 13 is used to input various operation information to the PDC portable mobile terminal.

First, the accumulation of character information data in a PDC portable mobile terminal will be described with reference to FIG. When the radio signal transmitted from the PDC base station 5 is received by the receiving circuit 10a (step S1), the logic unit 11 (accurately, the PU 11a) determines whether or not the radio signal includes character information data. Is performed (step S2).

If the CPU 11a determines that the character information data is not included, the CPU 11a terminates the storage process of the character information data. The character information data is extracted (step S3), and the extracted character information data is stored and stored in the memory 11b (step S4), and the storage process of the character information data ends.

Next, the display processing of the character information data thus accumulated in the memory 11b will be described with reference to FIG. First, when the user of the PDC portable mobile terminal performs an operation of calling the character information display function by the operation unit 13 (step S10), the CPU 11a
b, a request for extracting a character information item is issued.

Here, the character information data distributed via the PDC base station 5 is collected from a plurality of information sources in the information aggregation center 4 as described above, and the information items are diversified. It is huge. Memory 11b
Stores and classifies such character information data in, for example, a table format for each item of character information data. Under such circumstances, in order to provide only necessary information to the user, the character information items are first extracted from the memory 11b and output to the display unit 12.

The display section 12 displays the character information items input from the memory 11b (step S11). The user confirms the character information item displayed on the display unit 12,
The item number of the character information data to be taken out is input from the operation unit 13 (step S12). As a result, the CPU 11a
Requests the memory 11b to retrieve the individual information data specified by the item number. Memory 11b
Receives this request, reads out the character information data of the item number and outputs it to the display unit 12. Then, the display unit 12 displays individual character information data related to the individual information (step S13).

[0023]
