Abstract

PURPOSE:To attain simple check by providing a 1st ID memory storing an individual selective call number different from each receiver and a 2nd ID memory storing a selective call number for check. CONSTITUTION:As ID memories, a 1st ID-ROM 30 comprising an OTP (a ROM possible for write only once) and an EEPROM as a 1st ID memory and a 2nd ID-ROM 24a comprising a ROM disable of rewrite as a 2nd ID memory storing a selective call number for checking are employed. Thus, before an individual selective call number is written in the 1st ID-ROM 30, check is applied by using a selective call number for check stored in the 2nd ID-ROM 24a. Thus, it is not required to replace the ID memory or rewrite the ID memory, and simple check is attained.

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applied to radio selective calling receivers, and in particular, to a wireless selective calling receiver that improves the inspection method of radio selective calling receivers that have different selective calling numbers for each receiver. Relating to a selective call receiver.

〔overview〕

The present invention provides a wireless selective calling receiver having a different selective calling number for each receiver, which includes a first ID memory storing a selective calling number different for each receiver as an ID memory for storing the selective calling number; Inspection of the receiver is simplified by providing a second ID memory in which a selective call number for the receiver is stored.

[Conventional technology]

FIG. 5 is a block diagram showing an example of a conventional radio selective calling receiver.

Referring to FIG. 5, conventionally, this type of wireless selective call receiver has only one writable first ID-ROM 30 for storing a selective call number.

This ID-ROM is a ROM that can be written only once (one-time programmable read-only memory, hereinafter referred to as ○TP) or a ROM that can be electrically erased and rewritten (hereinafter referred to as EEPR).
It's called OM. > is used. After manufacturing radio selective call receivers at a factory, in order to test many receivers at the same time, in the case of ○TP, the ID-ROM of all receivers is
After replacing it with a D-ROM and inspecting it, it was replaced with an ID-ROM in which the selective call number for each receiver was written. Furthermore, when an EEPROM is used, a selective call number for testing is written once and a test is performed, and then the selective call number is rewritten to the selective call number for each receiver.

Furthermore, in addition to selective calling numbers for each receiver, some receivers have a common selective calling number for all receivers, and use the latter during factory inspections.

[Problem that the invention seeks to solve]

In the conventional radio selective calling receiver described above, when testing a large number of receivers at the same time, it is necessary to replace the ID-ROM (○
In the case of TP), it is necessary to rewrite the ID-ROM (in the case of EEPROM), which poses a problem in that it is time-consuming.

Furthermore, in the case where a selective calling number common to all receivers is provided in addition to a selective calling number specific to each receiver, both selective calling numbers must be detected at the same time, resulting in a problem that the hardware becomes complicated. Normally, in addition to the selective call number, the ID-ROM also stores information such as how to make a report (reporting time, whether to use a speaker when making a report, etc.).
There was a problem that this information could not be shared.

The purpose of the present invention is to solve the above-mentioned problems.
To provide a wireless selective call receiver that can easily perform a test without having to take the trouble to replace or rewrite an ID-ROM during the test.

[Means for solving problems]

The present invention provides a wireless signal receiving section, a memory for storing a selective calling number, and a received data processing for processing data received by the wireless signal receiving section and detecting a selective calling number stored in the ID memory. and a reporting unit that performs a reporting operation when the received data processing unit detects a selective calling number stored in the ID memory, wherein the ID memory is different for each receiver. It is characterized by including a first ID memory in which an individual selective call number is stored, and a second ID memory in which a selective call number for testing is stored.

Further, the present invention provides that the received data processing section
It is possible to add an ID memory specifying means for specifying in which of the D memory and the second ID memory the selective call number stored is to be detected.

Further, the present invention provides that the first ID memory is a read-only memory that can be written only once or an electrically erasable memory.
Preferably, the second ID memory is a rewritable read-on IJ-memory, and the second ID memory is a non-rewritable read-only memory.

Further, in the present invention, it is preferable that the received data processing unit includes a decoder and a CPU, and the second ID memory is provided in a partial area of a read-only memory included in the CPU.

[Effect]

The first ID memory stores an individual selective call number that is different for each receiver, and the second ID memory stores a selective call number for testing.

Therefore, before the individual selective call number is written in the first ID memory, the test can be performed using the test selective call number stored in the second ID memory, and it is not necessary to write the ID.
There is no need to replace or rewrite the memory, making it possible to perform inspections easily.
