Abstract

PURPOSE:To widen the range of utilizing service information and to improve convenience by providing a detecting means to detect the pattern of a first call number, call number setting holding means, first and second storing means and display means. CONSTITUTION:A ROM 14 previously stores the own call number and plural call numbers for message information reception, and these call numbers are read out according to an instruction from a CPU 11 and set to a call number setting holding circuit 15 in advance. The call number received by an antenna 20 is shaped to a digital signal by a waveform shaping part 17 after receiving amplification, detection and demodulation at a radio part 16. A decoder 18 compares a signal from the waveform shaping part 17 with the call number set to the call number setting holding circuit 15 in advance and announces the presence/absence of coincidence between the call number in the call signal and the previously set call number to the CPU 11 and when they are coincident, the CPU 11 stores the received information in a memory 19. Thus, the range of utilizing the service information utilizing the radio individual selective call receiver and the convenience can be increased.

In conventional information services, one of these call signals is allocated to send message information to multiple users.
A method is used in which information is transmitted intermittently to multiple wireless individual selective call receivers.

In conventional wireless individual selective calling receivers, the calling number for message information and the own calling number are stored in advance in the ROM built into the wireless individual selective calling receiver of the subscriber who wishes to use the information service. If the received calling signal IDx matches the own calling number, the user is notified that the call has been received by a buzzer, LCD display, etc., and if the received calling signal IDx matches the calling number for message information. The content was displayed on the LCD and also stored in memory.

[Problem to be solved by the invention]

The above-mentioned conventional wireless individual selective calling receiver has a structure in which a call number for receiving message information is stored in advance in the built-in ROM in order to receive information services, so only one type of message information can be received. , and cannot selectively receive other types of information services, and when switching the information service to be used, the ROM must be replaced at the service company, which narrows the scope of use of service information. However, the disadvantage is that it lacks convenience.

[Means to solve the problem]

The wireless individual selective calling receiver of the present invention receives a calling signal transmitted from a base station and sets its own calling number and a second number for receiving message information from an information service to an unspecified number of recipients. detecting means for detecting a predetermined pattern of a first calling number in the calling signal to identify whether it matches any of the calling numbers; and a plurality of second calling numbers for receiving the message information. a first storage means for storing a number in a first storage section in advance; and a second calling number of the object to be identified by reading out the plurality of second call numbers stored in the first storage section. When the second calling number in the calling signal matches the second calling number set and held by the calling number setting holding means and the second calling number set and held by the calling number setting holding means. It has second storage means for storing message information added to the calling signal in a second storage section, and means for displaying the message information stored in the second storage section on an LCD.
