Abstract

PURPOSE: A method for monitoring failure of a repeater is provided to discriminate whether a repeater has an error through an HLR(Home Location Register). CONSTITUTION: A management server extracts the number of a monitoring terminal of a repeater(S201), and extracts information on the number of the first registered exchange to be stored in a database of the management server(S203). An HLR checks a location registration time of the monitoring terminal matched to a corresponding terminal(S205). The management server extracts a monitoring terminal which has not been checked during the location registration time(S207). The management server checks information on a non-checked monitoring terminal through the HLR(S209). The management server searching information on the number of an exchange finally connected to the corresponding monitoring terminal by searching multiple exchanges connected to the HLR(S211). The management server stores the location registration time information and the number information of the exchange in an ARS server(S213). The management server calculates a time difference between location registration time of the monitoring terminal and information collection time(S215). If the time difference is more than 90 minutes, the management server regards the corresponding monitoring terminal as having been broken down(S217). The management server performs a paging test(S219). The ARS server performs an ARS on a corresponding subscriber(S221). When the ARS server receives a confirmation that the monitoring terminal has been broken down(S223), the ARS server informs an operator accordingly(S225).

Description

Repeater failure monitoring method {MONITORING METHOD FOR REPEATER TROUBLE}

The present invention relates to a repeater in a mobile communication system, and more particularly, to a repeater failure monitoring method for determining whether a repeater has a failure through a home location register (HLR).

In general, a repeater installed in large quantities, especially a repeater installed in an underground sales office may occur to close the repeater due to the transfer of the office. Or there is a sales office, but the number of subscribers increases, it is difficult to determine whether the specific repeater operation as the exchange (MSC) is replaced or reset.

After installing the first monitoring terminal, repeat the paging to monitor the failure. Paging receives information of the monitoring terminal, and receives the unique number, location information, and the like of the monitoring terminal. The exchanger receives the unique number and location information of the monitoring terminal installed in the repeater at regular intervals to determine the current operation state. The exchange performs paging based on the unique number of the initially set monitoring terminal.

Subsequently, when the exchange is replaced or the relay is closed or moved due to the increase in traffic of the repeater, the exchanger does not match the original set unique number of the corresponding monitoring terminal registered in the exchange. At this time, even if the exchange and the unique number do not match, the exchange performs paging with the monitoring terminal according to the unique number initially set for the monitoring of the repeater.

The exchange detects an error state as it performs paging with a unique number of an unmatched monitoring terminal. Such an error condition may occur even when there is no cause of failure of the repeater, and when a failure state of the repeater is received, the relevant manager is notified and unnecessary work is performed.

In other words, if the work efficiency is reduced due to a setting error of the monitoring terminal connected to the exchanger, or if it is mistaken for the loss of the repeater, additional equipment of the repeater is inevitable, thereby increasing the equipment cost. This causes a increase in the service charge of the communication service and causes a problem that the burden on the user increases.

The present invention has been made to solve the above problems, and an object of the present invention is to perform the final paging to the monitoring terminal based on the exchange number information first set in the monitoring terminal and the switch number information last set in the home location register. It provides a failure monitoring method of the repeater to determine whether the failure of the monitoring terminal through.

A failure monitoring method for a repeater according to an aspect of the present invention for achieving the above object, a) collecting the monitoring terminal information of the repeater to be tested; b) collecting initial exchange information registered with a number of the monitoring terminal; c) retrieving the location registration time of the monitoring terminal based on the exchange information; d) retrieving the last registered exchange number last registered from a home location register (HLR) with respect to the number information of the monitoring terminal for which the location registration time is not retrieved; e) calculating a time difference between the location registration time and the information collection time of the test state; f) determine whether the time difference is greater than or equal to the reference value, and if the time difference is less than or equal to the reference value, fetch the monitoring terminal information of the next repeater to be tested and feed back to step b), and if the time difference is greater than or equal to the reference value, the corresponding terminal based on the last exchange number information; Performing a plurality of paging to a monitoring terminal; And g) determining whether the monitoring terminal has a failure according to whether or not the paging is performed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an entire system according to the present invention. 2 is a flowchart for explaining the main operation of the present invention. As shown, it is composed of a home location register 107, an exchange 109, a management server 101, an ARS server 103, a communication server 105 and a mobile communication network 115.

The mobile communication network 115 communicates with a subscriber mobile communication terminal and a mobile communication terminal of an operating agent, including communication with the monitoring terminal 117. The ALS server 103 maintains an error reception database 111 and a subscriber database 113. The management server 101 may be a customer service management system (CSMS) server. The switching unit (MSC: Mobile Switching Center: 109) is registered for the first time in the monitoring terminal 117, the monitoring terminal 117 is a device for monitoring the repeater, in particular, is mounted on the underground repeater that the communication sensitivity is reduced .

The AP server 103 performs paging with a monitoring terminal 117 mounted on the repeater to monitor whether a repeater, for example, an underground repeater has failed. The paging operation is to receive terminal information from the monitoring terminal 117, and generates a failure list of all the repeaters already installed according to whether the terminal information is received.

The fault list information of the repeater may occur due to the replacement of the exchanger 109 initially registered in the monitoring terminal 117, and also the fault list information of the repeater may be generated due to the transfer / close of the repeater. In addition, as the unique number of the switch 109 is changed, paging to the repeater may not be performed, and thus may be extracted to the fault repeater. From this, when failure list information of the primary repeater is generated through paging, the management server 101 makes a database of the failure list information.

Step S201 is a sequential flow for sequentially searching for errors in the test terminal. The management server 101 first extracts the monitoring terminal number of the database-based repeater. Also, based on the extracted monitoring terminal number information, the switching unit 109 number information first registered in the monitoring terminal 117 is extracted. The extracted number information of the exchange 109 is stored in the database of the management server 101 (S203).

The extraction of the switch 109 number information is based on the registered information when the monitoring terminal 117 is first installed. The registration information can be obtained from a database of a predetermined repeater management computer.

The home location register 107 checks the location registration time of the monitoring terminal 117 matched with the corresponding switch 109 based on the number information of the switch 109 (S205). That is, by checking the last registered information exchange time between the switch 109 and the monitoring terminal 117, the position registration time is checked through the last registration information of the switch 109.

The location registration time information of the inspection completed monitoring terminal 117 is stored in the database of the management server 101, and extracts the monitoring terminal that is not confirmed in the location registration time inspection process (S207). The non-confirmed monitoring terminal 117 is a case where the first registered switch 109 number information is different or may be caused by a substantial failure cause. Accordingly, the management server 101 separately stores the monitoring terminal 117 information which is not confirmed in the database.

The management server 101 repeats the above process to generate list information of the non-confirmed monitoring terminal 117. The management server 101 queries the unidentified monitoring terminal 117 information through the home location register (HLR) 107 (S209). That is, a plurality of exchanges (MSC) 109 connected to the home location register 107 are searched to retrieve the number information of the switch 109 finally connected to the monitoring terminal 117 (S211).

The management server 101 stores the pre-stored location registration time information and the number information of the switch 109 in the RS server 103 (S213). In addition, the management server 101 monitors the location registration time information, that is, the location registration time of the monitoring terminal 117 which is finally detected from the switch 109 first registered in the monitoring terminal 117. A time for testing the user terminal 117, that is, a time difference with the information collection time is calculated (S215).

The calculated time difference information is provided to the ALS server 103, and when the ALS server 103 recognizes that the time difference between the location registration time and the information collection time is tens of minutes, for example, 90 minutes or less. The management server 101 determines that the monitoring terminal 117 is not in a fault state. Feedback to S201 to select a monitoring terminal to be tested next. On the other hand, if the time difference occurs more than 90 minutes, the management server 101 considers that the monitoring terminal 117 is a failure state (S217).

The management server 101 retrieves the exchange number information of the monitoring terminal 117 previously stored in the RS server 103. The retrieved information is provided to the ALS server 103 and performs paging to the monitoring terminal 117 with the corresponding exchange number. Paging is carried out a plurality of time intervals, for example, three times the paging test (S219).

That is, the paging test provides the switch number information stored in the RS server 103 and the unique number of the monitoring terminal 117 to the communication server 105, the communication server 105 for the switch and monitoring Paging to the monitoring terminal 117 through the mobile communication network 115 based on the unique number of the terminal 117.

If there is a response from the monitoring terminal 117 only once during the paging test, the paging test is performed again for a predetermined number of times, and if there is no response continuously for a predetermined number of times, the management server 101 receives the AL. The S server 103 finally determines that the monitoring terminal 117 is in a broken state. The final determination result is provided to the ALS server 103, and the ARS server 103 performs registration to indicate that the corresponding monitoring terminal 117 is in a fault state to the error reception database 111.

In addition, the ALS server 103 fetches subscriber information of the business place equipped with the monitoring terminal 117 from the subscriber database 113. The ALS server 103 performs an ALS to the corresponding subscriber based on the subscriber information (S221). ALS implementation is a procedure for checking a failure state directly from a subscriber, and notifies the subscriber that the monitoring terminal 117 is in a failure state through the communication server 105 and the mobile communication network 115.

If it is confirmed from the subscriber that the repeater, that is, the failure state of the monitoring terminal 117 from the ALS (S223), the ALS server 103 is notified to the operation personnel through the communication server 105. At this time, the packaged message is notified to the operation personnel in the form of a short message (S225).

The operating agent may be made a business trip for the troubleshooting of the monitoring terminal 117 to a specific place through a short message, it will be possible to replace the monitoring terminal 117 as necessary. The operating agent transmits the troubleshooting result of the monitoring terminal 117 to the RS server 103 through the mobile communication terminal, and the management server 101 based on the received information to the RS server 103. To grasp the current status of the troubleshooting of the monitoring terminal 117.

The RS server 103 modifies the registration information of the error reception database 111 according to the troubleshooting result information received from the operation personnel. Correction of the registered information corrects the fault list information of the monitoring terminal including the action history information.

As described above, the fault monitoring method of the repeater according to the present invention searches for the location registration time based on the exchange information of the initially set monitoring terminal, and only the monitoring terminal for which the location registration time is not retrieved is final through the home location register. Search the connected exchange number information, calculate the time difference between the location registration time and the information collection time, and perform a plurality of paging based on the corresponding exchange number information on the monitoring terminal that generates a difference over the reference time, and responds to the paging. If there is no fault reception and repair through the ALS is performed, not only the search for the fault repeater is accurate, but also the fault monitoring of the repeater is systematically achieved, thereby effectively managing the repeater.

What has been described above is only one embodiment for carrying out a method for monitoring a failure of a repeater according to the present invention, and the present invention is not limited to the above-described embodiment, as claimed in the following claims. Without departing from the gist of the present invention, one of ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.
