Abstract

PURPOSE:To confirm the receiving function of a receiver by a carrier at the time of the usual operation of a system, in a radio communication equipment used for a private branch pager. CONSTITUTION:A transmitter transmits a calling signal common to the system in each constant time, and a receiver is equipped with a calling mode switching means (i) by which the carrier can select the reception of a calling number specific to the receiver or the reception of the calling signal common to the system. Thus, the carrier can judge whether he is not called because the valid calling signal is not transmitted, or because the calling signal can not be received due to the deterioration of a surrounding radio wave circumstance or the like, by receiving the calling signal common to the system, and confirming the receiving function, so that the uneasiness of the carrier can be erased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio communication device used in a radio calling system for calling a specific person.

[0002]

2. Description of the Related Art In a conventional radio paging system, when a plurality of receivers are called, a transmitter sequentially transmits a transmission signal including an individual calling number of the receiver to be called. In a system that does not have means for transmitting information on whether or not a transmission signal is recognized to the transmitter side in real time, considering the reliability of communication or the possibility that the carrier goes out of the service area of communication, Repeated calls to the same receiver. Alternatively, it is retransmitted after a fixed time.

[0003]

When the above system is used as so-called in-house paging for arbitrarily calling a receiver carrier in a factory, office, etc., the call frequency effective for each receiver greatly differs. The wearer may not be called because the valid call signal is not sent to the receiver with which he / she is carrying, or the environment of the radio wave deteriorates due to surroundings even if a valid call signal is sent, and the receiver malfunctions. , Or the receiver cannot receive because the carrier is out of the communication service area. Therefore, there is a problem in that this kind of anxiety is attached to the wearer. There was also a problem that the reception function of the receiver could not be easily confirmed offline.

Therefore, an object of the present invention is to solve the above-mentioned conventional problems so that a carrier can confirm the receiving function of a receiver during normal system operation.

[0005]

In order to solve the above problems, the present invention sends a plurality of receivers each having a unique calling number and a transmission signal including a calling number corresponding to the unique receiver. In a radio paging system composed of a receiver, the receiver has a paging number peculiar to the receiver, a paging number storage means for internally storing a paging number common to the system, and a paging number peculiar to the receiver. Calling mode switching means for validating one of the calling numbers, a calling number stored in the calling number and calling number storage means included in the received transmission signal, and peculiar to the receiver selected by the calling mode switching means The transmitter has a data comparing means for transmitting a detection signal when the calling number is compared with one of the calling numbers common to the system and the calling numbers match. System call number storage means for storing a common call number, timer means for sending a transmission request signal at a predetermined arbitrary time, and transmission data construction means for incorporating the system call number storage means into a transmission signal when the transmission request signal is detected In order to alleviate the anxiety of the carrier, the carrier can confirm the receiving function of the receiver during normal system operation.

[0006]

In the wireless communication device configured as described above, a valid ringing signal is transmitted from the transmitter to all the receivers on the same system at every predetermined time, and each receiver is portable. It becomes possible to receive by the choice of the person.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a functional block diagram of a transmitter to which an embodiment of the present invention is applied. Calling number sending means b
Sends the calling number corresponding to the receiver to be called to the transmission data constructing means c.

The system call number storage means e stores a system call number common to the system. The transmission data constructing means c incorporates the calling number sent from the calling number sending means b and the system calling number storage means e into the transmission data in a predetermined format. The transmitter d sends out a radio signal modulated by the signal sent from the transmission data constructing means c. The timer means a sends out a transmission request signal of a system call number to the transmission data construction means at every predetermined time, and at that time, the transmission data construction means c causes the system call number storage means e to store the system call number. Embedded in the transmitted data.

FIG. 1B is a functional block diagram of a receiver to which an embodiment of the present invention is applied. The call number storage means f stores a call number unique to the receiver and a system call number common to the system. The signal received and demodulated in the receiving part g is sent to the data comparing means h, and when it coincides with the calling number stored in the calling number storage means f, a signal indicating the match detection is sent to the notifying means j. The mode switching unit i selects whether the calling number compared by the data comparing unit is a unique calling number or a system calling number common to the system. The mode switching means i is realized by an external switch such as a slide switch, and which one is selected is determined by the intention of the wearer.

[0010]

As described above, according to the present invention, the receiver has the calling number storage means, the mode switching means and the data comparing means, and the transmitter has the system calling number means, the timer means,
Since the transmission data constructing means is provided, the carrier can confirm the receiving function of the receiver during normal system operation, and the anxiety of the carrier can be eliminated.
