The configuration includes means.
[実施例コ 以下、図面にもとづいて本発明の詳細な説明する。[Example code] Hereinafter, the present invention will be explained in detail based on the drawings.
第1図は、本発明の一実施例に係る無線電話機の盗難対
策システムの処理手順を示す図である。FIG. 1 is a diagram showing a processing procedure of a wireless telephone anti-theft system according to an embodiment of the present invention.
ここでは、盗難電話機の呼に対する処理方法の選択によ
り、方式Aと方式Bの二つの方式を例にあげて説明する
。Here, two methods, method A and method B, will be explained as examples, depending on the selection of processing methods for calls from stolen telephones.
まず、無線電話機の盗難を確認した加入者1は、無線電
話の運用会社に無線電話機の盗難届け4を提出する。す
ると、運用会社は電話局2へ通知し、電話局2で盗難電
話機番号を登録する(処理5)。First, the subscriber 1 who has confirmed that the wireless telephone has been stolen submits a theft notification 4 of the wireless telephone to the wireless telephone operating company. Then, the operating company notifies the telephone office 2, and the telephone office 2 registers the stolen telephone number (processing 5).
一方、盗難者が発呼を行ない、盗難電話機3から電話局
2に発呼信号6が上がってきたとする。On the other hand, assume that the thief makes a call and a call signal 6 is sent from the stolen telephone 3 to the telephone office 2.
すると、電話局2は、盗難電話機3に対して盗難通知信
号7を送信し、その電話機が盗難状態にあることを通知
する。そして、この通知を受は取った盗難電話a!3は
、盗難通知内容とともに先に発呼した相手先の電話番号
を内蔵された不揮発性メモリに記憶させる(処理8)。Then, the telephone office 2 transmits a theft notification signal 7 to the stolen telephone 3 to notify that the telephone is stolen. Then, I received this notification from the stolen phone a! 3, the telephone number of the called party is stored in the built-in non-volatile memory together with the contents of the theft notification (process 8).
これは、後日回収されたときに読み出すことにより、盗
難電話機であることを確認するとともに、その電話機の
使用者に事情を問うことを可能にさせるものである。By reading this information when the telephone is recovered at a later date, it is possible to confirm that the telephone is a stolen telephone and to question the user of the telephone about the circumstances.
さらに、盗難電話機3は、盗難通知信号の受信確認とと
もに、先に発呼したときの相手先の電話番号を電話局2
に通知する(処理9)。Furthermore, the stolen telephone 3 not only confirms the reception of the theft notification signal but also sends the telephone number of the other party from the previous call to the telephone station 2.
(Process 9).
ここからは、方式Aと方式Bとの二つの処理方式の選択
ができる。From here, you can select two processing methods, method A and method B.
方式Aは、電話局2から直ちに盗難電話機3へ切断信号
10を送り、通話を拒否するものである。In method A, the telephone office 2 immediately sends a disconnection signal 10 to the stolen telephone 3 to reject the call.
この方式むこよれは、盗難電話機3の使用者に故障と思
わせて修理を促すことができ、この電話機3の回収を行
なうことを目的としている。This method of stealing can make the user of the stolen telephone 3 think that it is malfunctioning, prompting him to repair it, and is aimed at recovering the telephone 3.
一方、方式Bは、平常とおり通話を許可する(処理11
)ものの、電話局2て通話を録音する(処理12)。こ
の方式では、後で通話内容を分析し、盗難電話機3を使
用している者の手がかりを得ることを目的としている。On the other hand, method B allows calls as usual (processing 11
) However, the telephone station 2 records the call (processing 12). The purpose of this method is to analyze the contents of the call later and obtain clues about who is using the stolen telephone 3.
ここで、盗難電話機3からかけられた通話を録音する処
理12は、電子交換機が持っている悪意呼追跡機能を利
用することによって実現される。Here, the process 12 of recording a call made from the stolen telephone 3 is realized by using the malicious call tracking function of the electronic exchange.
以降は、方式A、方式Bともに盗難電話機3は通話終了
15に至り、電話局2では盗難電話機3からかけられた
相手先の電話番号および通話録音内容の分析を行なう(
処理13)。そして、盗難電話機3の使用者に関する情
報を収集して捜査に役立て、捜査当局あるいは盗難電話
機3の修理依頼により盗難電話機3の回収を行なうこと
が促進される。Thereafter, in both methods A and B, the stolen telephone 3 reaches the end of the call 15, and the telephone office 2 analyzes the telephone number of the other party called from the stolen telephone 3 and the recorded contents of the call (
Processing 13). Information regarding the user of the stolen telephone 3 is collected and used for investigation, and recovery of the stolen telephone 3 is facilitated by the investigative authorities or a request for repair of the stolen telephone 3.
[発明の効果コ
以上説明したように本発明は、無線電話機の携帯止が進
み、盗難に遭遇する確率が高くなっている昨今にあって
、盗難電話機の回収までの時間の短縮化を図ることが可
能な無線電話機の盗難対策システムを提供できるという
効果がある。[Effects of the Invention] As explained above, the present invention aims to shorten the time it takes to recover a stolen phone, in these days when wireless phones are becoming increasingly mobile and the probability of theft is increasing. This has the effect of providing an anti-theft system for wireless telephones that is capable of tampering.
すなわち、盗難電話機の使用者に関する情報を収集して
捜査能力を向上させることか可能となるとともに、盗難
電話機の使用者に故障と思わせて修理を促し、早期回収
が可能となる。That is, it becomes possible to collect information about the user of the stolen telephone to improve investigative ability, and it also makes the user of the stolen telephone think that it is malfunctioning and urges him to repair it, thereby enabling early recovery.
さらに、回収直後、この盗難電話機に内蔵された不揮発
性メモリの内容を読み出すことにより、電話局から無線
信号で送られた盗難通知内容と盗難後にかけた相手先の
電話番号が分かり、その場で盗難電話機であることが確
認できるため、この電話機の使用者に事情を問うことが
可能となり、盗難後の捜査性の向上と回収までの時間の
短縮化ができるという効果もある。Furthermore, by reading the contents of the non-volatile memory built into the stolen phone immediately after recovery, the content of the theft notification sent by wireless signal from the telephone office and the phone number of the other party called after the theft can be determined. Since it is possible to confirm that the telephone is a stolen telephone, it is possible to question the user of the telephone about the circumstances, which also has the effect of improving investigation performance after theft and shortening the time until recovery.
