(Other) Network Partner Monitoring

It is difficult for the database processing device 40 and the exchange connection guide device 20 connected to the same network to know the state of each other accurately. Therefore, the NPP 31 of the switched connection guide apparatus 20 simultaneously transmits an echo message to each CPU of the database processing apparatus 40 every second, and waits for the response of this message to arrive within 2 seconds. If the response message does not arrive, it is determined that the CPU has not reached the message and the call message is not transmitted to the CPU.

The SERVER-IN processor 41 of the database processing device 40 receives an echo message from the NPP 31 and delivers it to an ECHO-CATCHER processor (not shown). The ECHO-CATCHER processor processes this message and sends it to the SERVER-OUT processor 44, which forwards it to the NPP 31. If the echo message does not reach the ECHO-CATCHER processor within 3 seconds, the exchange connection guide device 20 determines that a failure has occurred and informs the SERVER-IN and SERVER-OUT processors 41.44 to handle the new virtual circuit connection request.

(Wave) load balancing function

Since the database processing device 40 is composed of two VAX computers and operates in ALL-ACTIVE to process different call messages at the same time, appropriate load balancing should be made among these CPUs. Since the original call message is generated in the switched connection guide device 2, the NPP 31 is responsible for load balancing. Although the messages should be transmitted to the CPUs with a low load, it is technically very difficult for the NPP 31 to know the load status of the CPU within a short time. Therefore, the NPP 31 transmits one by one at the moment of receiving a call message to each CPU.

As described above, the present invention provides an exchange access guide device for connecting and processing incoming calls on a public telephone network, a database processing device for collecting and managing change telephone numbers, and a communication control subsystem for communication between the two devices. It is easy to expand the capacity of the system according to the increase of subscribers, it is possible to interwork with the electronic exchange by R2 signaling method, and it does not need the manual work related to the main terminal box (MDF), providing convenience of operation and making emergency change. Data can be processed immediately, and it can be applied to various guide service fields as well as providing prompt and accurate guide information service.
