First of all, for continuous service of the redundant recording guide device, the continuous guide broadcast may be transmitted even if a physical abnormality of one side of the announcement is transmitted through the duplicated recording guide.

So blocking and unblocking are driven by the match exchange processor 10. When the match exchange processor 10 starts operation, the recording guide control unit 20 and the first and second recording guide units 30 are initialized. When the alarm occurs due to a malfunction of the hardware or a failure of the function from the recording guide unit during continuous monitoring, the recording guide control unit 20 detects this.

This is transmitted to the match exchange processor 10. The match exchange processor 10 checks the state of the alarm stored in the memory, and if the alarm is generated at both sides, the state of the channel is idle from Idle to FBLK (Fault Block). Transition to to manage the state.

In addition, if the channel is blocked and unblocked by the operator's request, the block request transitions to MBLK (MMC Block), and MBLK keeps MBLK until the release command is made even in the FBLK state.

Here, the recording guide device services 32 messages capable of recording up to 64 seconds for 2SHW (Sub HighWay). An adaptive differential pulse code modulation (ADPCM) decoder is used and erasable programmable read-only memory (EPROM) is used to efficiently use the memory. The recording guidance message is preserved even in the event of a power failure, and the recording guidance device is designed for remote recording and playback. Thus, the recording guide device transmits / receives a message and an electrical signal related to the recording guide control unit 20 and the time switch 60, which is a time division unit, and the like, and manages state by the matching exchange processor 10, and from the power supply device. The power is supplied.

On the other hand, the recording guide service is a recording guide service fixed to the requested channel when the request for the recording guide device to the recording guide control unit 20, the channel from the state management unit in the matching exchange processor 10 at this time It is determined whether to transmit the announcement broadcast according to the state of the channel by receiving the information of.

When the channel is blocked, the recording guide broadcast cannot be transmitted, and the service is provided only when the recording guide units 30 and 40 are idle.

So, according to the operator's request, the recording guides 30 and 40 are blocked / unblocked (ST1-ST3), and if the first and second recording guides 30 and 40 are normal, the first recording guide. The unit 30 is set to active and the second recording guide unit 40 is set to standby (ST4) (ST5). And if a failure occurs in one of the first and second recording guides 30 and 40, the display of the failure occurs in the recording guide, the recording guide service is performed to the recording guide that does not occur (ST6-ST8) . In addition, when a failure occurs in both the first and second recording guides 30 and 40, the first and second recording guides 30 and 40 display a failure (ST9) (ST10).

As described above, the service in the duplex recording guide device provides a guide broadcast by blocking one of the duplication recording guides by the recording guide control unit 20 and opening one side, and immediately blocking the physical abnormality of one side. By connecting the connected connection is a continuous announcement service is achieved.

As described above, the present invention is to implement the recording guide device in the switchboard for transmitting the announcement broadcast to the subscriber of the mobile communication system with redundancy.

As described above, the redundant recording guide device and the control method of the mobile communication system according to the present invention implements the recording guide device in the switch for transmitting the announcement broadcast to the subscribers of the mobile communication system in redundancy, according to the state management and By controlling the blocking and unblocking of the recording guide device, it is effective to enable continuous service even when a problem occurs in the recording guide device.
