Description

Prevention of lost charges due to failure of charging storage media in communication systems {IMPREMENTATION METHOD FOR PREVENTING CDR LOSS CAUSED BY STORAGE MEDIA PROBLEM IN TELECOMMUNICATION SYSTEMS}

According to the present invention, when a certain amount of charge is accumulated in a charge memory queue when a charge function is disturbed at an exchange, the present invention is notified to an external charge storage medium (charge settlement center), and the charge accumulated in the charge memory queue is settled online by a charge settlement center. Thereby, the present invention relates to a method of preventing the loss of charges which can prevent the loss of the charges due to the charging function failure of the exchanger and a computer-readable recording medium having recorded thereon a program for realizing the method.

1 is an exemplary configuration of a communication system in which a general exchange and a billing settlement center are interlocked.

As shown in FIG. 1, a communication system in which a general exchanger 10 and a billing settlement center 20 are interworked includes a billing generation unit 11, a call processing unit 12, and a billing transmission unit 13. It includes a switch 10 and a billing settlement center 20 connected to the billing transmission unit (13).

The call processing unit 12 performs call related tasks such as number translation, voice resource allocation, and additional service processing so that a telephone user can use a telephone.

The billing generation unit 11 generates a bill related to a call processed by the call processing unit 12 and temporarily stores it in the billing memory queue 14, and when a certain amount of billing is collected, the billing hard disk 15 or the billing magnetic field is charged. The tape 16 is stored.

The billing transmission unit 13 serves to transmit the billing generated to the billing settlement center (20).

In the related art, if a failure occurs in the charging storage medium 15 or 16 in the exchange 10 or a failure occurs in the charging transfer software SW, a loss of the charge occurs and online charging transfer and settlement are impossible.

That is, conventionally, when charging occurs in the exchanger 10, it is temporarily stored in the charging memory queue 14 and stored in the charging hard disk 15 when a predetermined amount is reached. At this time, if the charging hard disk 15 or the charging magnetic tape (MT) magnetic tape (MT) 16 or the like is not stored and stored in the charging memory rule 14, the charge is accumulated, if the predetermined time elapses in this state The charge on the memory queue 14 is discarded, and a lost call occurs to cause the loss of the charge.

These lost charges are output to the console screen or printer of the exchanger 10 through a Lost Call Dump. If the lost charges increase, the load on the exchanger 10 is increased, causing a chain failure. The lost charges dumped in this way have a problem that makes online automatic settlement impossible.

The present invention has been proposed to solve the above problems, when a certain amount of charge is accumulated in the charge memory queue when the charging function failure in the communication system to inform the external charge storage medium (charge settlement center), the charge A computer-readable record that records lost charges to prevent the loss of charges due to the charging malfunction of the exchanger and the program for realizing the above methods by performing the online charge settlement of charges accumulated in the memory queue to the billing settlement center.

In order to achieve the above object, the present invention provides a method for preventing a lost call due to a failure of a charging storage medium in a communication system, wherein the exchange periodically checks the storage means for the failure of the charging storage medium. A first step of detecting a situation in which charges accumulate in the account and notifying the billing settlement center (external storage medium); A second step of the exchange transferring the lost charge accumulated in the storage means to the billing settlement center after a failure occurs; And when the billing settlement center collects the charges normally from the exchanger and is notified that the lost charges accumulate in the storage means due to a failure of the exchanger, the lost charges accumulated in the storage means are collected and temporarily stored, And a third step of receiving the billing which was not transmitted before the failure occurred at the time of restoration and paying the billing together with the lost billing.

In order to achieve the above object, the present invention provides a communication system including a processor in order to prevent lost calls due to a failure of a charging storage medium. A first function of detecting a situation where charge is accumulated in the storage means and notifying the charge settlement center (external storage medium); A second function of sending, by the exchange, a lost charge accumulated in the storage means to the billing settlement center after a failure occurs; And when the billing settlement center collects the charges normally from the exchanger and is notified that the lost charges accumulate in the storage means due to a failure of the exchanger, the lost charges accumulated in the storage means are collected and temporarily stored, The present invention provides a computer-readable recording medium having recorded thereon a program for realizing a third function of receiving a charge not transmitted before a failure occurs and performing settlement with the lost charge. In order to charge, the loss is detected before the charge occurs and sent to the external storage medium (billing settlement center) online.The charge generated at the exchange cannot be stored due to the failure of the charge storage medium, and the memory accumulates in the memory for a certain time. In this case, it is no longer possible to store the charge in the memory. In general, the lost charge is caused by a lost call dump (LostCall Dump), while the present invention prevents the loss of the charge by using the external storage medium (bill settlement center). In general, the exchange manages the memory queue. In the present invention, when a certain amount of charge is accumulated in the memory queue, the exchange detects the notification and informs the settlement center and transmits the accumulated charge of the memory queue. In this case, the settlement center collects the charges normally at the exchange and when the exchange is notified that the charges are accumulated in the memory queue, the exchange collects and stores the charges accumulated in the memory queue. If this is done, the process is settled by the conventional method. The present invention prevents the loss of charge in the exchanger and By presenting a way to charge the line, it prevents the loss of the charge due to the failure of the exchange, prevents the chain failure of the exchange, thereby contributing to the stabilization of the operation of the exchange, and automating the billing settlement online even in the event of the exchange can do.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, when the charge generated by the exchange cannot be stored in the charge storage medium due to a failure of the charge storage medium (the charge hard disk or the charge magnetic tape) of the exchange, the external charge storage medium (charge settlement center) as another storage medium. Is to utilize. The charge processed in this way is defined as 'Pseudo Lost Call'.

FIG. 2 is a detailed diagram illustrating an embodiment of a non-lost charging process in the charging generator according to the present invention. The charging generator 11 monitors the charging memory queue 14 of the exchange 10. When the charge memory queue 14 detects that a predetermined amount of charges are accumulated, the notification is notified to the billing settlement center 20, and a procedure for transmitting a non-lost charge is shown.

The present invention is to prevent the loss of charges that may occur in the exchanger 10 and to settle on-line billing, it is detected before the loss is generated and transmitted online to the billing settlement center 20, which is an external billing storage medium. That is, the billing generation unit 11 of the exchanger 10 manages the billing memory queue 14, and when a certain amount of billing is accumulated in the billing memory queue 14, the billing settlement center 10 informs the billing settlement center 10. The accumulated charge is transferred to the charging memory queue 14. At this time, the accounting settlement center 20 collects the charges normally in the exchange 10, when accumulates in the charge memory queue 14 due to the failure of the exchange 10, accumulates in the charge memory queue 14 Collected charges are temporarily stored in the file system 21, and when the failure situation of the exchange 10 is terminated, the charges that are not transmitted before the failure is received and processed as lost charges and settled by the existing method.

The exchange 10 should be able to detect the occurrence of lost charges due to the failure of the charging storage medium 15, 16 in advance. To detect before the lost charges are generated in the exchange 10, The state in which the charge is stored (that is, the usage of the charge memory queue 14) may be monitored. That is, a limit value of the appropriate charging memory queue 14 is set in consideration of the charging generation amount and the load in the maximum call occurrence time of the exchange 10, and when the usage of the charging memory queue 14 exceeds this value, the state of expected loss of charging is expected. Judging by

If a charge loss is expected in the exchanger 10, it should be notified to the billing settlement center 20 and changed to a 'loss expected billing state', and the exchanger 10 will transfer the estimated loss loss from the billing settlement center 20. After responding that the preparation is completed, the charging of the charging memory queue 14 is started. At this time, the billing settlement center 20 receives the billing transmitted from the exchange 10 and stores it in the file system 21 regardless of the continuity with the billing received before the failure.

As shown in FIG. 2, the charging generation unit 11 processes non-lost charging in a state in which the charging generation unit 11 always accesses the charging memory queue 14, and the charging memory queue 14 is used. Since it manages the Read Point and the Write Point of, there is an advantage that it is easy to manage the billing memory queue 14, but there is a disadvantage that the billing transfer function should be added.

Referring to FIG. 3, another example of a process of monitoring the usage of the charging memory queue 14 of the exchange 10 and processing the non-lost charging is as follows.

3 is a detailed description of another embodiment showing a non-lost charging process in the charging transmitter according to the present invention, in which the charging transmitter 13 monitors the charging memory queue 14 of the exchange and then the charging memory queue. If it is detected in (14) that a certain amount of charge has accumulated, it is notified to the billing settlement center 20, and the procedure for transmitting the non-lost charge is shown.

As shown in FIG. 3, the charging transfer unit 13 processes the non-lost charging in which the charging transfer unit 13 accesses the charging memory queue 14 and the charging memory queue 14 after the non-lost charging processing. Although it is difficult to access the read point and the write point of the data in the form of mutual exclusion with the charge generation unit 11, the original function is utilized in the portion of the non-lost charge transmission. There is an advantage.

2 and 3, the exchanger 10 collects the billing for each call to a certain size to make a billing block, and gives a block number in the order of creation. These billing block numbers generally exist as a unique number from the exchange 10 to the billing settlement center 20. At this time, if the accounting settlement center 20 is notified of the occurrence of non-lost charge due to the failure of the exchanger during the normal charging process, it ignores the existing work and performs the non-lost loss until the charging function of the exchange 10 becomes normal. Gold will be sent and stored temporarily. Afterwards, when the exchange 10 returns to normal, the billing settlement center 20 is generated before the failure of the exchange 10 and stored in the charge storage medium 15 and 16 of the exchange 10 but not received. The system checks the continuity of the billing block number, the talk time in the billing, and the reverse of the time by combining the billing and the non-logging bill collected in the event of a failure, and verify whether the billing is lost and whether it is billable.

4 is a detailed flowchart illustrating a lost charging process in an exchange in a method of preventing a lost charging according to the present invention. The procedure of managing the charging memory queue 14 and detecting a failure situation in the exchange 10 is shown in FIG. Indicates.

In the present embodiment will be described according to the non-lost charge generation process by the charge generation unit 11 as described above in FIG.

As shown in FIG. 4, the lost charging process in the exchanger of the lost charging method according to the present invention is performed when the charge for the call processed by the call processing unit 12 is stored in the charging memory queue (401). In operation 402, the billing generator 11 analyzes the amount of the billed memory queue 14 used.

As a result of the analysis, if the usage of the billing memory queue 14 is greater than a certain value (usage usage> Size Limit), after the non-lost billing is transmitted to the outside (403), it is checked whether the billing memory queue is being accessed (404) or less. If it is, it is checked if the charging memory queue is being accessed (404).

As a result of the check, if the charging memory queue 14 is being accessed somewhere, it waits (405). If not, the corresponding charging block of the charging memory queue 14 is deleted and the memory queue management information is modified (406). Thereafter, after waiting for a predetermined time (407), the process proceeds to step 401 where the charging for the call processed by the call processing unit 12 is stored in the charging memory queue.

FIG. 5 is a detailed flowchart illustrating a process of storing a bill in a billing settlement center in a method of preventing a lost bill according to the present invention, and shows a procedure for non-loss accounting in the billing settlement center 20.

As shown in FIG. 5, the billing storage process in the billing settlement center of the lost billing prevention method according to the present invention is first performed from the exchanger 10 while the billing settlement center 20 is performing normal billing processing (503). When the signal message is received (501), the billing settlement center 20 analyzes whether the message received from the exchange 10 is a non-lost billing transmission status request signal (502), the non-lost billing transmission status request signal (that is, In the case of a non-lost charge generation message, non-lost charges are collected until return to the normal state (504, 505).

If returning to the normal state during the collection, it is checked whether there is a charge that could not be collected before the failure (506), and if there is a charge that could not be collected, after collecting the charge before the failure (507) A non-lost charge is verified (508), and if it does not exist, a non-lost charge collected due to a failure is immediately verified (508). The method of the present invention as described above is implemented as a program and is a computer-readable recording medium. (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

The present invention as described above, to prevent the loss of charges due to the failure of the exchange, thereby preventing the chain failure of the exchange thereby contributes to the stabilization of the operation of the exchange, it is possible to automate the billing settlement online in the event of a charge failure of the exchange. It has an effect.
