Description

Translated fromJapanese

本発明は、インターネットプロトコル電話機収容交換システム(IP−PBXシステム)、特に、IPネットワーク側の障害発生時に、IP電話機の通話を確保するために接続先を切り替える制御方法に関する。  The present invention relates to an Internet protocol telephone accommodation and exchange system (IP-PBX system), and more particularly, to a control method for switching a connection destination in order to ensure a call on an IP telephone when a failure occurs on the IP network side.

従来のこの種のIP−PBXシステムの例が特許文献1に記載されている。このIP−PBXシステムは、電話機を収容するIP−PBX端末の間で、IPネットワークおよびIP−PBX本体を経由して音声パケットを送受信することにより、電話機の間で通話をしているときに、IP−PBX本体またはIPネットワーク障害(ネットワーク障害という)の発生等によりIP−PBX端末が動作不能となった場合、アナログ局線を経由した通話に緊急に切り替えることによって電話機の間での通話を確保する。  An example of a conventional IP-PBX system of this type is described inPatent Document 1. This IP-PBX system transmits and receives voice packets between IP-PBX terminals that accommodate telephones via the IP network and the IP-PBX main unit, thereby making a call between telephones. If an IP-PBX terminal becomes inoperable due to the occurrence of an IP-PBX main unit or an IP network failure (referred to as a network failure), etc., a call between telephones is secured by urgently switching to a call via an analog line. To do.

緊急切り替えは、IPネットワークを介した通話とアナログ局線を経由した通話の終了の確認を受けた後で行い、また復旧後のアナログ局線からIPネットワークへの緊急切り戻しは、アナログ局線を経由した通話の終了の確認を受けた後で行うことにより、ユーザーの通話が突然に切断されることがないようにしている。  Emergency switching is performed after confirming the end of the call via the IP network and the call via the analog station line, and the emergency switchover from the restored analog station line to the IP network is performed using the analog station line. This is done after receiving confirmation of the end of the call that has passed, so that the user's call is not suddenly disconnected.

本発明によれば、ネットワーク上に設置された電話機に対するネットワーク障害発生時に、その電話機を一旦外部音源装置へ切り替え接続して通話状態を保持し、その状態で切替え先の電話機を呼び出し、応答があると、その電話機を切替え先の電話機へ切り替えることとしたため、ネットワーク障害発生時においても通話を維持したままで電話機を別の電話機に切り替えることが可能となる。  According to the present invention, when a network failure occurs in a telephone set installed on the network, the telephone is once switched and connected to the external sound source device to maintain the call state, and the switch destination telephone is called and responded in that state. Then, since the telephone is switched to the switching destination telephone, it is possible to switch the telephone to another telephone while maintaining the call even when a network failure occurs.

次に、本発明の実施の形態について図面を参照して説明する。  Next, embodiments of the present invention will be described with reference to the drawings.

図1は、本発明の一実施例であるIP−PBXシステムの構成を示す図である。このIP−PBXシステムは、多数の利用者が所有するIP電話機6bがIPネットワーク3に接続されると共に、その利用者が所有する公衆回線加入者電話機(加入者電話機)6cが公衆回線網7に接続されている。なお、図面の煩雑化を回避するために1利用者のみを図示する。  FIG. 1 is a diagram showing a configuration of an IP-PBX system which is an embodiment of the present invention. In this IP-PBX system, anIP telephone 6b owned by a large number of users is connected to theIP network 3, and a public line subscriber telephone (subscriber telephone) 6c owned by the user is connected to thepublic line network 7. It is connected. Note that only one user is shown in order to avoid complication of the drawing.

IPネットワークにはLAN制御装置2を介してIP−PBX1が接続され、IP−PBX1には公衆回線網7と内線用電話機6aが接続されている。また、IP−PBX1には、外部音源装置5および電話機切替え管理メモリ4も接続されている。内線用電話機6aと加入者電話機6cはアナログ信号で作動する通常の電話機である。  An IP-PBX 1 is connected to the IP network via theLAN controller 2, and apublic line network 7 and an extension telephone 6a are connected to the IP-PBX 1. In addition, an externalsound source device 5 and a telephone switch management memory 4 are also connected to the IP-PBX 1. The extension telephone 6a and thesubscriber telephone 6c are ordinary telephones that operate with analog signals.

LAN制御装置2はIP電話機6bとIP−PBX1との間の通信状態を常時監視し、通信が途絶えた場合にはIP−PBX1へ通信が途絶えたIP電話機6bの番号を通知する手段を具備する。  TheLAN control device 2 is provided with means for constantly monitoring the communication state between theIP telephone 6b and the IP-PBX 1 and notifying the IP-PBX 1 of the number of theIP telephone 6b whose communication has been interrupted when the communication is interrupted. .

IP−PBX1は、内線用電話機6a、IP電話機6b、加入電話機6cおよび外部音源装置5が利用者によるイベントを通知する呼制御パケットを受信する手段と、内線用電話機6a、IP電話機6b、加入電話機6cおよび外部音源装置5に音声情報の送信受信の指示や状態の変更を通知する呼制御パケットを送信する手段を具備する。  The IP-PBX 1 includes an extension telephone 6a, anIP telephone 6b, asubscriber telephone 6c, and means for receiving a call control packet for notifying an event by a user, an extension telephone 6a, anIP telephone 6b, and a subscriber telephone. 6c and a means for transmitting a call control packet for notifying the externalsound source device 5 of an instruction for transmission / reception of voice information and a change in state.

内線用電話機6aとIP電話機6bはIP−PBX1の内線電話機として使用され、加入電話機6cは外線電話機として使用される。IP−PBX1は、内線用電話機6aと加入電話機6cからのアナログ信号をIPパケット化し、また内線用電話機6aと加入電話機6cへのIPパケットをアナログ信号化する。  The extension telephone 6a and theIP telephone 6b are used as extension telephones of the IP-PBX 1, and thesubscriber telephone 6c is used as an external telephone. The IP-PBX 1 converts analog signals from the extension telephone 6a and thesubscriber telephone 6c into IP packets, and converts IP packets to the extension telephone 6a and thesubscriber telephone 6c into analog signals.

また、IP−PBX1は、IP電話機6bから、特番により電話機切替え管理メモリ4に切替え電話機番号を登録する手段と、LAN制御装置2から通信が途絶えたIP電話機6bの番号を受信する手段と、通信が途絶えたIP電話機6bの番号を受信したときに、外部音源装置5へ一旦接続して通話を保持した上で、電話機切替え管理メモリ4を参照し、IP電話機6bから切り替え先番号の電話機へ切り替える手段を具備する。  Further, the IP-PBX 1 communicates from theIP telephone 6b with means for registering the telephone number to be switched to the telephone switching management memory 4 by a special number, with means for receiving the number of theIP telephone 6b with which communication has been interrupted from theLAN control device 2, When the number of theIP telephone 6b that has been interrupted is received, the telephone is temporarily connected to the externalsound source device 5 to hold the call, and the telephone switching management memory 4 is referenced to switch from theIP telephone 6b to the telephone of the switching destination number. Means.

図2は、電話機切替え管理メモリ4が格納する電話機切替えテーブルの内容を示す。このテーブルには、ネットワーク障害時に切り替えられる電話機の番号であるIP電話機番号と、切替え先の電話機の番号である電話機切替先番号を対の形で登録される。切替え先の電話機としては、一般的には、IP電話機6bを所有する利用者が所有する加入電話機6cが選ばれる。また、外部音源装置5は、音声ガイダンスや保留音などに利用される音楽をIP−PBX1へ送信する。  FIG. 2 shows the contents of the telephone switching table stored in the telephone switching management memory 4. In this table, an IP telephone number that is a telephone number to be switched when a network failure occurs and a telephone switching destination number that is a telephone number of a switching destination are registered in pairs. Generally, thesubscriber telephone 6c owned by the user who owns theIP telephone 6b is selected as the telephone to be switched to. In addition, the externalsound source device 5 transmits music used for voice guidance, music on hold, and the like to the IP-PBX 1.

電話機切替え管理メモリ4への切替え電話機番号の登録は、IP電話機6bから特番1x+加入電話機番号090−xxxx−xxxxを設定し、IP−PBX1に対して行なう。IP−PBX1は、この設定を受けて、電話機切替え管理メモリ4に切替え電話機番号の登録を行う。電話機切替え管理メモリは登録を行ったIP電話機すべての電話機切替え先番号を管理する。  Registration of the switching telephone number in the telephone switching management memory 4 is performed for the IP-PBX 1 by setting the special number 1x + subscription telephone number 090-xxxx-xxxx from theIP telephone 6b. Upon receiving this setting, the IP-PBX 1 registers the switching telephone number in the telephone switching management memory 4. The telephone switching management memory manages telephone switching destination numbers of all registered IP telephones.

次に、図3〜図5を参照して、ネットワーク障害発生時の電話機切替え処理について説明する。  Next, telephone switching processing when a network failure occurs will be described with reference to FIGS.

先ず、正常時には、例えば、IP電話機6bと内線用電話機6aとは、IPネットワーク3、LAN制御装置2およびIP−PBX1を経由して通話を行なっている。LAN制御装置2はIP電話機6bとIP−PBX1との間の通信状態を常時監視している。  First, at the normal time, for example, theIP telephone 6b and the extension telephone 6a make a call via theIP network 3, theLAN control device 2, and the IP-PBX1. TheLAN control device 2 constantly monitors the communication state between theIP telephone 6b and the IP-PBX 1.

内線用電話機6aとIP電話機6bとの通話中にネットワーク障害が発生し通話が途絶えた場合図(3)、LAN制御装置2はネットワーク障害発生を検出し、IP−PBX1へ通信が途絶えたIP電話機6bの番号を通知する。IP−PBX1はLAN制御装置2から通信が途絶えたIP電話機6bの番号を受信後、内線用電話機6aとIP電話機6bとの接続を内線用電話機6aと外部音源装置5への接続に切り替える(図4)。外部音源装置5は内線用電話機6aにIP電話機6bが電話機切替え中であることをアナウンスする。  When a network failure occurs during a call between the extension telephone 6a and theIP telephone 6b, the call is interrupted. FIG. 3 (3). Report thenumber 6b. The IP-PBX 1 switches the connection between the extension telephone 6a and theIP telephone 6b to the connection between the extension telephone 6a and the externalsound source device 5 after receiving the number of theIP telephone 6b whose communication has been interrupted from the LAN controller 2 (see FIG. 4). The externalsound source device 5 announces to the extension telephone 6a that theIP telephone 6b is being switched.

次に、IP−PBX1は、IP電話機6bの番号により電話機切替えテーブルを参照し、そこに登録されている電話機切替え先番号を得る。いま、電話機切替え先番号が加入電話機6cを指すものとすると、IP−PBX1は加入電話機6cへ呼出しを行う(図4)。加入電話機6cが応答すると、内線用電話機6aと外部音源装置5の接続を、内線用電話機6aと加入電話機6cとの接続に切り替えられる(図5)。  Next, the IP-PBX 1 refers to the telephone switching table by the number of theIP telephone 6b, and obtains the telephone switching destination number registered there. Now, assuming that the telephone switching destination number indicates thesubscriber telephone 6c, the IP-PBX 1 calls thesubscriber telephone 6c (FIG. 4). When thesubscriber telephone 6c responds, the connection between the extension telephone 6a and the externalsound source device 5 is switched to the connection between the extension telephone 6a and thesubscriber telephone 6c (FIG. 5).

以上のような制御を行うことで、ネットワーク障害発生時に内線用電話機6aを切断することなく、IP電話機6bからIP−PBX1へ登録した加入電話機6cへ切り替えて通話を維持することが可能となる。  By performing the control as described above, it becomes possible to maintain the call by switching from theIP telephone 6b to thesubscriber telephone 6c registered in the IP-PBX 1 without disconnecting the extension telephone 6a when a network failure occurs.

電話機切替え管理メモリ4に格納する電話機切替えテーブルは、図6に示すように、ネットワーク障害時に切り替えられる電話機の番号であるIP電話機番号毎に、切替え先の電話機の番号である複数の電話機切替先番号を登録することもできる。このときの登録は、先ず、IP電話機6bから特番1x+迂回順位1+加入電話機番号090−xxxx−xxxxを設定し、次に、同様の方法で、特番1x+迂回順位2+加入電話機番号090−yyyy−yyyyを設定する、ということを迂回数だけ繰り返すことにより行なう。電話機切替え管理メモリ4は登録を行ったIP電話機すべての電話機切替先番号を管理する。  As shown in FIG. 6, the telephone switching table stored in the telephone switching management memory 4 includes a plurality of telephone switching destination numbers that are switching telephone numbers for each IP telephone number that is a telephone number that is switched when a network failure occurs. Can also be registered. In this registration, first, the special telephone number 1x + thebypass order 1 + the subscriber telephone number 090-xxxx-xxx is set from theIP telephone 6b, and then the special number 1x + thebypass order 2 + the subscriber telephone number 090-yyyy-yyyy in the same manner. This is done by repeating the number of times of detouring. The telephone switching management memory 4 manages telephone switching destination numbers of all registered IP telephones.

これにより、図7に示すように、ネットワーク障害発生時に、IP−PBXは迂回順位1である切替え先の加入電話機6cへ呼び出しを行うが、加入電話機6cが一定時間応答しなかった場合、迂回順位2である加入電話機6dへ呼び出しを行なう。このような手順を迂回順位に従って、電話機切替え先番号が電話機切替え管理メモリ4に登録されている切替え先番号の電話機ごとに繰返し行う。そして、応答があり次第、内線用電話機6aと外部音源装置5の接続を内線用電話機6aとその加入電話機との接続に切り替える。  As a result, as shown in FIG. 7, when a network failure occurs, the IP-PBX calls the switchingdestination subscriber telephone 6c having thebypass priority 1, but if thesubscriber telephone 6c does not respond for a certain time, thebypass priority 2 to thesubscriber telephone 6d. Such a procedure is repeated according to the detour order for each telephone having the telephone switching destination number registered in the telephone switching management memory 4. As soon as a response is received, the connection between the extension telephone 6a and the externalsound source device 5 is switched to the connection between the extension telephone 6a and the subscriber telephone.

以上のような制御を行うことで、ネットワーク障害発生時に内線用電話機6aを切断することなく、また登録した切替え先の加入電話機6cが応答できない場合においても、IP電話機6bからIP−PBX1へ登録した迂回先の加入電話機(例えば、6d)へ切り替えて通話を継続することが可能となる。  By performing the control as described above, theIP telephone 6b registers with the IP-PBX 1 without disconnecting the extension telephone 6a when a network failure occurs and even when the registeredswitching destination telephone 6c cannot respond. It is possible to continue the call by switching to a bypass destination subscriber telephone (for example, 6d).

以上の説明は、IP電話機6bに対する電話機切替えについてであったが、図8に示すように、アナログ信号で作動する通常の電話機である内線用電話機6eについても、同様に内線用電話機6eから加入電話機6cへ切り替えることができる。この場合は、IP−PBX1aが内線用電話機6eに対するアナログ信号とIPパケットの変換を行なっており、また、LAN制御装置2aが内線用電話機6eとIPネットワーク3との間の通信状態を常時監視し、通信が途絶えた場合にはLAN制御装置2へ通信が途絶えた内線用電話機6eの番号を通知する。LAN制御装置2は、そのことをIP−PBX1へ通知し、IP−PBX1が内線用電話機6aの接続先を加入者電話機6cへ切り替える。  The above description is about the telephone switching to theIP telephone 6b. However, as shown in FIG. 8, theextension telephone 6e, which is a normal telephone operated by an analog signal, is similarly changed from theextension telephone 6e to the subscriber telephone. It is possible to switch to 6c. In this case, the IP-PBX 1a converts analog signals and IP packets for theextension telephone 6e, and the LAN control device 2a constantly monitors the communication state between theextension telephone 6e and theIP network 3. When communication is interrupted, the number of theextension telephone 6e for which communication has been interrupted is notified to theLAN control device 2. TheLAN control device 2 notifies the IP-PBX 1 of this, and the IP-PBX 1 switches the connection destination of the extension telephone 6a to thesubscriber telephone 6c.
