本発明は一般電話交換網に関し特に区域内通話
を閉番号で区域間通話を開番号で行なう閉番号と
開番号との変換電話方式に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a general telephone exchange network, and more particularly to a conversion telephone system between a closed number and an open number in which calls within an area are made using a closed number and calls between areas are made using an open number.
従来、電話網は同一の加入者番号が存在しない

区域内網と、開放番号方式で運用されている区域
間網とでは、その桁数および意味が異なつてくる
ことは当然である。従つて区域内網と区域間網は
物理的に明確な分離をしておく必要があり、相互

なわち第１図に示すように区域内網１内の通話
（点線Ａ）は閉番号で運用され、区域間網２を通
る通話（点線Ｂ）は開番号で運用される。 Traditionally, telephone networks have used closed number system for intra-area calls (so-called local calls), where the same subscriber number is dialed and connected within an area, and area numbers with a prefix such as "0". There are inter-area calls (so-called long-distance calls) using the open number system, which are connected by dialing and then dialing the subscriber number. The number of digits and the meaning of the selective digit information that subscribers send between exchanges differs between local networks operated using a closed numbering system and interarea networks operating using an open numbering system. Of course it will come. Therefore, it is necessary to keep a clear physical separation between the intra-area network and the inter-area network, and even if they are connected to each other, mutual use cannot be considered. For example, it is not possible to connect intra-area calls using an inter-area network operated with open numbers, and it is not possible to connect intra-area calls using an intra-area network operated with closed numbers. I can't even connect. That is, as shown in FIG. 1, calls within the local network 1 (dotted line A) are operated using closed numbers, and calls passing through the inter-area network 2 (dotted line B) are operated using open numbers.
このように両網が区別されていても従来の伝送
技術は近距離である区域内（市内）伝送方式と遠
距離である区域間（市外）伝送方式が大きく違つ

グからデイジタル化されていく通信網においては
その差がなくなり相互の共用が有用となつてく
る。 Even though the two networks are differentiated in this way, in conventional transmission technology, the short-distance intra-area (intra-city) transmission method and the long-distance inter-area (out-of-town) transmission method were very different, resulting in poor transmission quality. There was also a difference, so it was not a problem. However, in communication networks where the transmission and switching systems are changing from analog to digital, this difference disappears and mutual sharing becomes useful.
本発明の目的は区域内網と区域間網の相互の利
用を可能とすることにより経済的で柔軟性に富ん
だ通信網の運用を行なう閉番号と開番号の変換電
話網方式を提供することにある。 An object of the present invention is to provide a closed number/open number conversion telephone network system that enables economical and flexible communication network operation by enabling mutual use of intra-area networks and inter-area networks. It is in.
本発明の変換電話方式は区域内接続をする交換
機に加入者がダイヤルした区域内通話の選択数字
情報に区域番号を付加する機能を設けることによ
り、区域内通話でも開番号を使用した区域間網に
乗り入れることも出来るし、また区域内網に開番
号運用をした網を作り、区域内通話を乗り入れさ
せることが出来るようにしたものである。 The conversion telephone system of the present invention provides an inter-area network that uses open numbers even for intra-area calls by providing a function for adding an area number to the selected number information for calls within the area dialed by the subscriber in the exchange that connects within the area. In addition, a network with open number operation was created within the area network, and it was possible to make calls within the area.
次に本発明の実施例を第２図と第３図にて説明
する。 Next, an embodiment of the present invention will be explained with reference to FIGS. 2 and 3.
第２図は区域内網１に開番号運用の網１′を作

わちの呼は区域内網１の呼でありながら区域間
網２を利用して接続している。また(b)の呼は区域
間網２内を通過する呼であるかが、区域内網１の
開番号運用網１′を利用して接続している。 FIG. 2 shows a state in which a network 1' for open number operation is created in the intra-area network 1 and used mutually with the inter-area network 2. In other words, the call is connected using the inter-area network 2 even though it is a call on the intra-area network 1 . The call in (b) is a call that passes through the inter-area network 2, but is connected using the open number operation network 1' of the intra-area network 1.

はかることができる。 FIG. 3 is a relay system diagram for explaining the functions added to the exchange. Subscriber SUB dials the closed number 73-1111 and switches frame SW
Information is stored in the register sender RS connected to the output side of the register. When the register sender RS enters an open number operation network (either intra-area network 1' or inter-area network 2), it adds its own area number 427 and sends it as 427-73-1111. In this way, the switching network can be used economically depending on whether or not the own area number is added on the sending side of the switching equipment.
本発明は以上説明したとおり閉番号の呼を開番

内網と区域間網の相互乗り入れを行なう経済的な
変換方式が得られる。 As explained above, the present invention is configured so that a call from a closed number can be changed to an open number, thereby providing an economical conversion method for mutually connecting an intra-area network and an inter-area network.
