BACKGROUND OF THE INVENTION
The present invention relates to a method and method for reducing a “status notification message” in a voice processing apparatus, and more particularly to a voice processing apparatus that manages encoding / decoding processing of voice data for mobile communication in a mobile communication system. When a change in the operational status of each functional unit installed in the device is detected for maintenance purposes, a `` status notification message '' to be transmitted to the mobile communication switching device that is the host device of this voice processing device is The present invention relates to a method of reducing a “status notification message” in a voice processing device and a method thereof that can avoid occurrence of a large amount.
[0002]
[Prior art]
FIG. 1 is a diagram showing an embodiment of a mobile communication system. A mobile communication switch 1, a voice processing device 2, a radio base station device 3, a mobile communication switch 1 and a voice processing device 2 are provided. The exchange side transmission path 4 to be connected, the base station side transmission path 5 to which the voice processing apparatus 2 and the radio base station apparatus 3 are connected, the mobile communication exchange 1 and the voice processing apparatus 2 are connected, and control data and the like are transmitted and received. And a control line 6 to be configured. This conventional speech processing apparatus 2 includes a monitoring control unit 21 that manages the operation state in the apparatus, an exchange-side transmission line termination unit 22 that terminates a transmission line with the mobile communication exchange 1, a radio base station apparatus 3, The base station side transmission path termination unit 24 terminates the transmission path of the first and second transmission paths, and an encoding / decoding unit 23 (0 to N) for encoding / decoding data. The radio base station apparatus 3 includes a transmission path termination unit 31 facing the base station side transmission path termination unit 24 in the speech processing apparatus 2, and an encoding / decoding unit 23 (0 to N) in the speech processing apparatus 2. It is comprised from the transmission / reception unit 32 which opposes.
[0003]
The “status notification message” in the conventional speech processing apparatus 2 having such a configuration occurs in the following cases. That is, the supervisory control unit 21 periodically obtains the latest operational status (implementation, failure, error, etc.) of each functional unit, and edits the “status notification message” when a change in operational status of a functional unit is detected. To the mobile communication switch 1. Even when an event that commonly affects the operation state of the encoding / decoding units 23 (0 to N) installed in the apparatus occurs, the supervisory control unit 21 makes a plurality of “status notifications”. Message "was sent to the mobile communication switch 1 all at once.
[0004]
For example, a failure or the like occurs in the base station side transmission path 5 with the radio base station apparatus 3, and the operation state of the base station side transmission path termination unit 24 that terminates the base station side transmission path 5 is abnormal and recovered. Is repeated, the specific bit of the time slot on the base station side transmission path 5 is transmitted between the transmission / reception unit 32 of the radio base station apparatus 3 and the encoding / decoding unit 23 (0 to N) in the speech processing apparatus 2. Since it is used for synchronization, the encoding / decoding unit 23 (0 to N) is out of synchronization (error). The supervisory control unit 21 detects a change in the operating state of the encoding / decoding unit 23 (0 to N), and transmits a “status notification message” to the mobile communication switch 1. Since a large number of encoding / decoding units 23 (0 to N) are mounted, a large number of “status notification messages” of the respective encoding / decoding units 23 (0 to N) are generated.
[0005]
This simultaneous transmission of the “status notification message” causes congestion of the mobile communication switch 1 and reduces the processing capability of the mobile communication switch 1, and thus has a great adverse effect on the mobile communication system.
[0006]
In order to reduce the simultaneous transmission of such “status notification messages”, conventionally, when the exact same message is requested to be output continuously, the second and subsequent outputs are only the message ID, and the same message ID is used. When a message with a part of the content continues, only the message ID and the difference are output (for example, see Patent Document 1).
[0007]
[Patent Document 1]
JP-A-1-306919 (page 1-2, FIGS. 1 and 2)
[0008]
[Problems to be solved by the invention]
The conventional method of reducing the simultaneous transmission of the “status notification message” described above does not reduce the number of messages even if only the message ID is transmitted. Even if the decoding unit 23 (0 to N) is out of synchronization (error), in the case of a failure in the transmission path 5 on the base station side with the radio base station apparatus 3, each encoding / decoding unit Although there is no need to edit the “status notification message” of 23 (0 to N), there is a problem that a large number of messages are generated.
[0009]
The present invention has been made in order to improve the above-described circumstances. Accordingly, an object of the present invention relates to a speech processing apparatus that controls encoding / decoding processing of speech data for mobile communication in a mobile communication system. When the processing device detects a change in the operating state of each functional unit installed in the device for maintenance purposes, a “status notification message” is sent to the mobile communication switching system that is the higher-level device of this voice processing device. Another object of the present invention is to provide a method for reducing a “status notification message” in a voice processing device and a method thereof that can avoid the occurrence of a large amount.

The
[0023]
Next, the details of the monitoring control unit 21 of the voice processing device 2 will be described with reference to FIG.
[0024]
FIG. 2 is a detailed block diagram illustrating an example of a monitoring control unit of the voice processing device.
[0025]
Referring to FIG. 2, the monitoring control unit 21 of the present embodiment stores the main processing unit 211 that operates by program control and the operation state data of each functional unit (22, 23, 24) in the voice processing device 2. And a transmission processing unit 213 that transmits a “status notification message” to the mobile communication switch 1 via the control line 6.
[0026]
The main processing unit 211 compares the latest operation state of each functional unit (22, 23, 24) in the voice processing device 2 with the operation state data storage unit 212, and detects monitoring means 2111 that detects a change in the operation state. And message editing means 2112 for editing a message to be transmitted to the mobile communication exchange 1 which is a higher-level device.
[0027]
The transmission processing unit 213 adds a header to the transmission message and transmits a “status notification message” via the control line 6 to the mobile communication switching device 1 which is a higher-level device, and the traffic on the control line 6 Traffic monitoring means 2132 for monitoring the traffic.
[0028]
Each of these means generally operates as follows.
[0029]
The monitoring unit 2111 inquires each functional unit for the latest operating state of each functional unit at a predetermined monitoring cycle, and compares it with the operating state of the functional unit stored in the operational state data storage unit 212. Thus, a change in the operating state of the functional unit is detected. When the notification is received from the traffic monitoring unit 2132, the monitoring cycle of the functional unit is changed.
[0030]
The message editing unit 2112 updates the information area of the corresponding functional unit in the operation state data storage unit 212 with the contents of the operation state change of the functional unit detected by the monitoring unit 2111, and sends a “status notification message” to the mobile communication switch 1. ”Is converted to a specified message format and the message is edited. The “status notification message” generated by the message editing unit 2112 is delivered to the protocol processing unit 2131.
[0031]
The protocol processing means 2131 performs signal processing according to the protocol of the control line 6 and sends a “status notification message” to the control line 6.
[0032]
The traffic monitoring unit 2132 monitors the output of the protocol processing unit 2131 and calculates the traffic on the control line 6. When the traffic amount calculated by the traffic monitoring unit 2132 exceeds a preset threshold, the monitoring unit 2111 is notified.
[0033]
Next, referring to FIGS. 3 and 4, the overall operation of the present embodiment shown in FIGS. 1 and 2 will be described in detail.
[0034]
FIG. 3 is a time chart for explaining how the monitoring period is changed according to the present embodiment.
[0035]
First, the monitoring unit 2111 of the main processing unit 211 of the monitoring control unit 21 shown in FIG. 2 periodically inquires each functional unit about the operational status of all the functional units mounted on the voice processing device 2. There are two types of monitoring cycles for inquiring, and the monitoring cycle is usually “T1” (“T1” in the lower part of FIG. 3). An MJ notification (a notification that the amount of traffic on the control line 6 has exceeded the threshold value “S1” from the traffic monitoring unit 2132 is referred to as an “MJ notification” in the sense of “major notification”. 3), the monitoring cycle is changed to “T2” to increase the monitoring cycle (“T2” in the lower part of FIG. 3). From the traffic monitoring means 2132, the MN notification (notification that the traffic amount of the control line 6 has fallen below the threshold value “S2”. It is referred to as “MN notification” in the sense of “minor notification”. Is received as point B.), the monitoring cycle is changed to “T1” and the monitoring cycle is restored (point B in the lower part of FIG. 3).
[0036]
The order of monitoring the operation state of each functional unit in the speech processing apparatus 2 is ascending order (0) of the exchange side transmission line termination unit 22, the base station side transmission line termination unit 24, and the encoding / decoding unit 23 (0 to N). To N).
[0037]
FIG. 4 is a flowchart for explaining the procedure for monitoring the operating state of the encoding / decoding unit. The monitoring procedure for other functional units is the same.
[0038]
In FIG. 4, the monitoring unit 2111 makes an inquiry to the encoding / decoding unit 23 (0) and obtains the latest operation state data from the encoding / decoding unit 23 (0) (step A1). By comparing the latest operational state data of the encoding / decoding unit 23 (0) with the operational state data of the encoding / decoding unit 23 (0) stored in the operational state data storage unit 212, the code A change in the operating state of the encoding / decoding unit 23 (0) is detected (step A2). If there is no change in the operating state of the encoding / decoding unit 23 (0) (No in step A2), the process is terminated (proceeds to step A6). Here, when the operation state of the encoding / decoding unit 23 (0) changes (Yes in step A2), the message editing unit 2112 causes the encoding / decoding unit 23 (0) of the operation state data storage unit 212 to change. ) Is updated (step A3), the message is edited to transmit the “status notification message” (step A4), and the “status notification message” is output to the transmission processing unit 213 (step A5). .
[0039]
Next, in the transmission processing unit 213 of the monitoring control unit 21 that has received the “status notification message”, the protocol processing means 2131 adds a header or the like to the “status notification message” that is the output of the message editing means 2112, and the control line 6. To send. The traffic monitoring unit 2132 concurrently monitors the traffic status of the control line 6 and outputs an MJ notification to the monitoring unit 2111 when the traffic amount of the control line 6 exceeds the threshold value “S1” (FIG. 3), when the amount of traffic on the control line 6 falls below the threshold “S2,” an MN notification is output to the monitoring means 2111 (point B in FIG. 3).
[0040]
Next, the operation of this embodiment will be described using a specific example.
[0041]
In FIG. 1, for example, the base station side transmission path 5 is abnormal, and the operation state of the base station side transmission path termination unit 24 repeats occurrence of error and error recovery. Similarly, the encoding / decoding unit 23 (0 to N) repeats error generation and error recovery. At this time, the monitoring unit 2111 detects a change in the operation state of the base station side transmission line termination unit 24 and the encoding / decoding unit 23 (0 to N), and generates a large number of “status notification messages” as a result. Will do. As a result, the traffic on the control line 6 becomes high, and the traffic monitoring means 2132 detects that the traffic volume has changed from low to high and has exceeded the threshold “S1” (point A in the upper part of FIG. 3). The MJ notification is output from the traffic monitoring unit 2132 to the monitoring unit 2111. The monitoring unit 2111 receives the MJ notification and changes the monitoring cycle from “T1” to “T2” (point A in the lower part of FIG. 3). The magnitude relationship between the monitoring periods is set to T1 <T2. For this reason, the monitoring cycle becomes longer and slower, and as a result, the “status notification message” is suppressed, and the traffic on the control line 6 decreases. When the traffic on the control line 6 decreases and falls below the threshold “S2” of the traffic volume (point B in the upper part of FIG. 3), the traffic monitoring means 2132 outputs an MN notification to the monitoring means 2111. The monitoring unit 2111 receives the MN notification and changes the monitoring cycle from “T2” to “T1” (point B in the lower part of FIG. 3).
[0042]
Note that the values of the monitoring periods “T1” and “T2” and the threshold values “S1” and “S2” of the traffic amount used in the present embodiment are arbitrary values as system parameters of the voice processing device 2. A configuration that can be set is assumed.
[0043]
As described above, in the present embodiment, the traffic on the control line 6 between the voice processing device 2 and the mobile communication switch 1 is monitored, and the monitoring cycle is changed according to the traffic amount on the control line 6. Therefore, a processing mechanism for dynamically controlling the “status notification message” generated at the timing of the monitoring cycle is provided, and the transmission of a large amount of “status notification message” from the voice processing device 2 can be suppressed. It will be a thing. As a result, it is possible to avoid congestion of the mobile communication switching system 1.
[0044]
Next, a second embodiment of the present invention will be described with reference to FIG.
[0045]
FIG. 5 is a time chart for explaining how the monitoring cycle is changed in the second embodiment.
[0046]
Referring to FIG. 5, in the second embodiment of the present invention, there are three types of threshold values (S11, S12, and S2) of traffic volume monitored by the traffic monitoring unit 2132, and the monitoring unit 2111 monitors This is different from the first embodiment in that there are three types of cycles (T1, T21, and T22).
[0047]
That is, in the second embodiment, it can be assumed that the traffic of the control line 6 does not decrease even if the monitoring period of the monitoring unit 2111 is changed to “T2”. The notification is set in two stages (MJ1 and MJ2), and the monitoring period of the monitoring means 2111 is assigned corresponding to each.
[0048]
The operation of the second embodiment will be described in detail with reference to FIG.
[0049]
The traffic monitoring means 2132 monitors the traffic on the control line 6 and outputs an MJ1 notification to the monitoring means 2111 when the traffic volume exceeds the threshold “S11” (point A in the upper part of FIG. 5). Upon receiving the MJ1 notification, the monitoring unit 2111 changes the monitoring cycle to “T21” (point A in the lower part of FIG. 5). The traffic monitoring unit 2132 monitors the traffic on the control line 6 and outputs an MJ2 notification to the monitoring unit 2111 when the traffic volume exceeds the threshold “S12” (point B in the upper part of FIG. 5). Upon receiving the MJ2 notification, the monitoring unit 2111 changes the monitoring cycle to “T22” (point B in the lower part of FIG. 5). The traffic monitoring unit 2132 monitors the traffic on the control line 6 and outputs an MN notification to the monitoring unit 2111 when the traffic volume falls below the threshold “S2” (point C in the upper part of FIG. 5). Upon receiving the MN notification, the monitoring unit 2111 changes the monitoring cycle to “T1” (point C in the lower part of FIG. 5).
[0050]
