Abstract

PURPOSE:To write and rewrite a 2nd selective call No. by radio with no direct connection secured to an exclusive writing device by providing a selective call No. write/rewrite control circuit to a radio selective call receiver in order to receive a selective cell No write/rewrite command signal. CONSTITUTION:A radio selective call receiver contains the storage elements 5 and 6 having a 1st selective call No. area 201 storing the individual selective call Nos and a 2nd selective call No. area 202 storing one or more selective call Nos respectively. In the area 202 the selective call No. can be electrically written and rewritten. That is, a selective call No. write/rewrite control circuit 203 performs the write/rewrite control to store the call No. date in the area 202 based on the individual selective call No. included in a reception signal, a selective call No. write/rewrite command signal, and the call No. data on the selective call No. Thus the selective call No. of the storage element is set or rewritten based on the radio data given from a service source at reception of a new service or at change of the service source. Thence the labor and the time required for these operations can be omitted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is utilized in a wireless selective calling receiver having a plurality of selective calling numbers. In particular, the present invention relates to a wireless selective calling receiver that sets or changes a second selective calling number using wireless data.

〔overview〕

The present invention enables the user to bring the receiver to a service company etc. by setting and changing the selective calling number on the storage means in the wireless selective calling receiver in accordance with the wireless data. This is designed to save you time and effort.

[Conventional technology]

The selective calling number of a conventional wireless selective calling receiver is FROM
is written in. In order to write or rewrite the selective calling number, connect the FROM itself to a dedicated writer, or connect the receiver in which the FROM is installed to a dedicated writer. was. This was the same even if there were two or more selective calling numbers.

[Problem to be solved by the invention]

In this way, in conventional wireless selective calling receivers, the selective calling number is written using a dedicated writing device, so it is necessary to write or rewrite the selective calling number when the receiver is already in service. In some cases, the user has to bring the receiver to the service company and write the number, which is inconvenient.

Note that writing or rewriting the selective calling number is necessary in the following cases. For example, as shown in the table, it is assumed that each selective call number is assigned to the information receiving service. Here, if the information service recipient is receiving stock information and foreign exchange information services, the FROM in the receiver contains selective call numbers IDI, ID2, and I
D3 is written. Here, selective calling number IDI
Individual selective calling number unique to the receiver, selective calling number ID2
is the selective call number for receiving stock information, selective call number TD3
is a selective calling number for receiving foreign exchange information. If the information service recipient wishes to receive news information instead of stock information, it is necessary to rewrite the selective call number ID2 in the PROM to the selective call number ID4. However, conventional receivers have the disadvantage that writing or rewriting the calling number must be performed using a dedicated writing device provided by a service company or the like.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wireless selective calling receiver that can easily register and change a second selective calling number.

(hereinafter referred to as non-purchase margin) [Means for solving the problem] The present invention has a first area for storing an individual selective calling number;
