Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio paging receiver, and more particularly to a radio paging receiver capable of changing paging means.

[Conventional technology]

Conventionally, as a radio paging receiver capable of changing the calling means, there has been a radio paging receiver which can be changed by attaching a changeover switch to the radio paging receiver itself. In some cases, the operation mode of a certain calling means is changed according to a 2-bit multi-address pattern following the pager ID number of the calling signal.

[Problems to be solved by the invention]

Of the above-mentioned conventional radio paging receivers, the former cannot change the calling means from the calling side, and the latter can change the operation mode of a certain calling means from the calling side, but can be selected. Since the selection range is very narrow, with a maximum of four patterns, it is not possible for the calling side to appropriately select the calling means desired to be used and the operation mode for each of the calling means. There is a drawback that it is not possible to make an appropriate call according to.

[Means for solving the problem]

The radio paging receiver of the present invention includes at least two of a plurality of paging means including a ringing paging means, a vibrator paging means, a message display paging means, and a light emission paging means. A first function of detecting a signal that matches an ID number, and when detecting a signal that matches the own pager ID number, specifies one of the calling units and specifies an operation mode of the specified calling unit. A control unit having a second function of detecting a control signal in the received signal and a third function of operating the calling unit based on the detected control signal.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

 FIG. 1 is a block diagram of one embodiment of the present invention.

In this embodiment, 1 is a wireless receiving unit, 2 is a decoding unit for a data signal received by the wireless receiving unit 1, and 3 is a control corresponding to its own pager ID number and a command number as shown in FIG. The ROM 4 having the item information, the control item status information corresponding to the parameter number, and the basic status information of each calling device, 4 compares the pager ID number received from the decoder 2 with its own pager ID number. When the two pager ID numbers match in this comparison, the decoder 2 analyzes the data consisting of the command number and parameters sent from the decoder 2 to the pager ID number and the information in the ROM 3 to control each device for calling. A control unit having a function of performing the following operations: 5 is a buffer for holding a message; 6 is a message display; 7 is a light emitter;
8 is a speaker, and 9 is a vibrator. Control unit 4 is CP
Realized by U.

FIG. 3 is a flowchart showing the sequence of operations in this embodiment. The operation of this embodiment will be described with reference to FIG.

When the present embodiment is first operated, the control unit 4 controls the calling device of the message display 6, the light emitting device 7, the speaker 8, and the vibrator 9 according to the information on the basic state of each calling device in the ROM 3. Are initialized (step 101). For example, speaker-on, message display-on, vibrator-off, operation time of all paging devices-10 sec, speaker sound pattern-
It is set like the pattern of parameter number 0.
When this initial setting is completed, a pager ID number reception wait state is entered (step 102). This state continues until a pager ID number matching the pager ID number in the ROM 3 is transmitted from the decoder 2.

FIG. 4 is an explanatory diagram of the format of the data signal output from the decoder 2 to the control unit 3. This format is PO
CSAG (Post Office Code Stanardization Advisory Gro
up) signal format (CCIR Rec.584).
SC in the data signal indicated by reference numeral 10 is a synchronization bit, G1 to
G8 is a group consisting of two 32-bit code words.

Each codeword begins with a 1-bit flag and ends with a 1-bit parity bit, as indicated by reference numeral 11. The code word with the flag “0” is a call signal,
It contains 18 bits of the address which is the pager ID number, 2 bits of the multi-address (MA) described above, and 10 check bits. The code word whose flag is “1” is a control signal, and includes 20-bit data and 10-bit check bits. As shown by reference numeral 12, the 20-bit data is composed of five groups of 4 bits called digits, and each command number shown in FIG. 2 and parameters corresponding to each command number are Expressed in units of this digit. Each command number is 4 bits, so it is represented by 1 digit. Parameters are also 1 digit except for messages.
Is represented by

If a call signal having an address that matches the pager ID number is obtained (step 103, YES), verification of the command number is started (step 104). The command number and the parameter are transmitted in the command format illustrated in FIG. 5 following the pager ID number. When receiving a plurality of command numbers and parameters, it is necessary to detect a break between the first parameter and the second command number. As described above, each parameter other than each command number and message is 1 digit
The method of detecting the delimiter between the command number and the parameter by attaching an 8-bit parameter indicating the message length before the parameter indicating the message content is used for the message parameter.

When the number registered as the command number is obtained (step 104, YES), the process enters the parameter collation, and when the parameter collation is completed (step 105),
From the command number and parameter information and the information in the ROM 3, it is analyzed which calling device should be set to which operation mode, and the calling device is set in accordance with the analysis result (step 106). If the registered command number is 0100 in FIG. 2, a parameter indicating the message content is stored in the buffer 5. The parameters of the speaker sound pattern specify the length of the sound (indicated by-and ， in FIG. 2). When the same command number is received twice or more, the parameter of the last received command becomes valid. When the device setting is completed, the process is performed again for the next command number.

If a command other than the registration is received as the command number (step 104, NO), the reception is terminated there and the calling operation is started in the calling device setting state at this time (step 10).
7). At this time, if the message display 6 is ON and a message is stored in the buffer 5, the message is displayed on the message display 6.

When the calling is completed, each calling device is reset to the initial basic state (step 101), and the process waits for reception of the pager ID number again.

In this embodiment, one command number is associated with one parameter, but as shown in FIG.
If the required number of command numbers is reduced by increasing the number of parameters corresponding to one command number,
The required number of signal bits can be saved.

〔The invention's effect〕

As described above, according to the present invention, it is possible to select a device to be used for calling and the functions of these devices by a control signal from the calling side, and the selection range is very wide. There is an effect that an appropriate paging device and its function can be used according to the purpose, the content of the message, and the like at each time.
