Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a message storage and switching apparatus, and more particularly to a non-delivery detection system.

[0002]

2. Description of the Related Art In a message storage and exchange device, when data once stored cannot be transmitted to a designated destination due to a line failure or the like, a non-delivery notification notifying a service requester that communication was not possible. Service. Conventionally, in the non-delivery detection method of this message storage and exchange device, a non-delivery notification is defined by a time non-delivery method that defines a non-delivery time meaning a time limit when data is transmitted to a destination, and a retry method that attempts communication a plurality of times. Service was realized.

[0003]

In such a non-delivery detection method in a message storage and exchange device, if a communication request is received by the storage and exchange device that exceeds a data amount that can be processed within a predetermined time, the non-delivery time must be reached by the non-delivery time. There is a problem that non-delivery cannot be detected.

[0004] An object of the present invention is to calculate a transmission amount that can be processed by a storage and switching device within a predetermined time in advance, and immediately notify a non-delivery request to a request that does not terminate communication until a clear non-delivery time. It is an object of the present invention to provide a non-delivery detection method in a message storage and exchange device capable of performing the above-mentioned operations.

[0005]

According to the non-delivery detection method in the message store and exchange apparatus of the present invention, a non-delivery time which means a time limit when data is transmitted to a destination is defined and set in advance. Time definition means, line group management means for pre-defining and setting the data transmission rate and the number of accommodated lines of this group for each line group, and management and failure of unreachable subscribers when data is unsuccessful. Non-delivery management means for outputting a notification of arrival, and a line group for calculating and storing, for each line group, a first data amount indicating a data transmission rate in the set non-delivery time and a communication capability with the number of accommodated lines. A communication capacity management means, a stored data amount management means for storing and managing a second data amount indicating a stagnated data amount for each line group, and a line group corresponding to the destination subscriber information; When receiving a data transmission instruction, the subscriber data management means refers to the subscriber data management means to determine a line group of a corresponding destination by destination subscriber information, and determines the first data amount in the line group. The second data amount is compared with the second data amount. If the second data amount is larger than the first data amount, a non-delivery is notified to the non-delivery management unit, and the second data amount is If the data amount is smaller than the first data amount, the destination analysis means determines that the communication process is possible, and adds the data accumulated from the subscriber when the communication process is determined to be possible to the second data amount. And a stay data subtracting means for subtracting the end of the communication process from the second data amount when the communication process is completed.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a non-delivery detection method in a message storage and exchange apparatus according to one embodiment of the present invention.

[0008] The destination analyzing unit 12 analyzes the destination of the data 11 stored from the accommodation subscriber (not shown). The accumulated data amount management unit 13 calculates the amount of uncommunicated data added by the accumulated data addition processing unit 15 and the accumulated data subtraction processing unit 17.
Is managed as the staying data amounts D1 to Dn corresponding to the line groups. The line group communication capability management unit 14 sets the line speed for each of the line groups K1 to Kn defined in the line group management unit 21 at the time of system restart and the line group non-delivery time definition unit 22 based on the lines L1 to Ln used. Automatically calculates the amount of data that can be communicated per non-arrival time. The non-delivery management unit 16 outputs a non-delivery notification if there is a non-delivered subscriber when the management of the non-delivered subscribers and the communication processing of all destinations are completed. The subscriber data management unit 20 manages subscriber data, and the non-delivery time definition unit 22 manages the non-delivery time.

The operation of the message storage and exchange device having the above configuration will be described. Line group communication capability management unit 14
Is based on the line speed, the number of accommodated lines, and the unreachable time defined by the unreachable time definition unit 15 for each line group defined in the line group management unit 21 at the time of the restart processing.
For example, the amount of data that can be processed in one hour is calculated,
It is set in the corresponding line group G1 to Gn.

After the restart, the data 11 stored by the subscriber
Are processed by the destination analysis unit 12 to develop the destination. When receiving the service designation for transmitting data, the destination analysis unit 12 obtains the line group Lx to which the destination subscriber belongs from the subscriber data management unit 20, and communicates with the stored data amount management unit 13 corresponding to this line group. The communication capabilities in the group communication capability management unit 14 are compared.

When the data amount of the accumulated data amount management unit 13 is larger than the data amount of the corresponding line group communication capacity management unit 14, it is determined that the processing cannot be performed within the non-delivery time, and the non-delivery management unit 16 is notified of the non-delivery. . If it is determined that the data amount of the accumulated data amount management unit 13 is smaller than the data amount of the line group communication capability management unit 14 and processing can be performed within the non-arrival time, the staying data addition processing unit 15 becomes a target of destination analysis. The data amount of the stored data is added to the corresponding stay data of the stay data amount management unit 13.

When there are a plurality of destinations, the staying data in the accumulated data amount management unit 13 and the line group communication capability management unit 1
The comparison of the communication capabilities in 4 is repeated for the destination. When the communication with the destination subscriber is completed, the stay data subtraction processing unit 17
Accordingly, the amount of staying data in the accumulated data amount management unit 13 of the line group to which the destination subscriber belongs is subtracted.

[0013]

As described above, according to the present invention, by judging a communication request that cannot be clearly processed within the non-delivery time, the present invention can promptly send a data transmission request that is determined not to end communication within the non-delivery time. By processing as non-delivery, there is an effect that the early notification of the communication result and the staying data transmission request can be reduced.
