Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

In the drawings of the present invention, the same reference numerals are assigned to components that perform the same functions unless the functions are specifically distinguished.

1 is a view schematically showing a repeater remote management system using a PDA according to an embodiment of the present invention. Referring to Figure 1, the repeater remote management system using a PDA of the present invention, personal digital assistants (personal digital assistants, hereinafter referred to as "PDA", 11), mobile repeater control system (mobile repeater control system, hereinafter " mRCS ”, 13), the interlocking server 15, the repeater monitoring server (17).

The PDA 11 performs the function of displaying the current repeater status information connected to the relay monitoring server 17, displaying alarms occurring in the repeater, controlling the repeater status, configuring the PDA 11, connecting the CDMA PPP, and upgrading the program. .

The mRCS 13 is interlocked with the interlocking server 15, the repeater monitoring server 17, and the PDA 11 to perform functions such as user authentication database configuration, local database, and server management.

The interworking server 15 receives the current repeater data from the repeater monitoring server 17 and performs a database. To this end, the interlocking server 15 is configured as a database management system (hereinafter referred to as "DBMS") system, and the DBMS is a communication control unit (hereinafter referred to as "CCU") of all these repeaters. , Short Message Service (hereinafter referred to as “SMS”) repeater status data, alarm data of all repeaters, operational history data for all repeaters, configuration information related to specifications, status monitoring data of repeater monitoring servers 17 And so on.

The repeater monitoring server 17 collects the state and alarm information of each repeater from the CCU server 19 and the SMS server 21. And retains this collected current repeater status. The data retained include configuration information, alarm data storage, CCU repeater 31 and SMS repeater 31 status data, LOG data, user information, program information (Version), and the like. In addition, in consideration of a content matching problem with the interlocking server 15 DB, that is, in case of network disconnection, the relay server 15 holds data, and loads data when reconnecting. That is, the CCU repeater 31 and the SMS repeater 31 state data, alarm data, operation history data, and the like are loaded.

The interface between the systems of the above components is as follows. The mRCS 13 and the PDA 11 communicate by HTTP. The mRCS 13 and the interlocking server 15 communicate with the OJD (Oracle Jdbc Driver). The mRCS 13 and the repeater monitoring server 17 communicate with each other through a socket (TCP / IP). The self-management and statistics function of the mRCS 13 uses a web browser.

Here, although not shown, the repeater DB reference information is unified by interlocking the enterprise resource planning (Enterprise Resource Planning, hereinafter referred to as "ERP") and the interlocking server 15.

In addition, the repeater monitoring server 17 is connected to the exchange 25 via the CCU server 19 or via the SMS server 21 and the SMS center 23, which is connected to each base station 27. Connected with The base stations 27 are connected to the respective CCU repeaters 31 through the node distributor 29 or to the SMS repeaters 31 through the radio.

It describes the process of remote management of the repeater using the repeater remote management system using the PDA of the present invention configured as described above.

2 is a flowchart illustrating a method of operating a repeater remote management system using a PDA according to an embodiment of the present invention. Referring to FIG. 2, a user performs a CDMA PPP connection using the PDA 11 (S11). When the PDA 11 attempts a PPP connection to the CDMA using the Ras API of the operating program WinCE, the CDMA attempts a PPP registration to the Ras server of the network. When PPP connection is made between CDMA and Ras server of the network, “CONNECT” signal is sent to PDA 11, and PDA 11 performs system binding with the IP address assigned to TCP / IP system of the operating program.

Thereafter, the user authentication process is performed, when the user inputs his / her ID / PASSWORD (S13) and requests authentication, the PDA 11 transmits authentication data to the mRCS 13 (S15) and thus the mRCS 13 In step S17 to S19, the user authentication table of the interlocking server 15 is searched to determine whether the user is a valid user, and then the authentication is transmitted to the PDA 11 (S21). The PDA 11 receives the authentication presence packet and moves to the main menu, for example, "find repeater" when authentication is completed. It is preferable that the authentication cycle of the user is from the beginning to the end of the program.

At this time, when the authentication is completed in the above authentication process, the program upgrade management is performed in the mRCS (13). That is, when the user of the PDA 11 obtains user authentication after logging in, the program version information of the mRCS 13 is checked at the same time as the user authentication (S23). If a new version is checked, an OK response is transmitted (S25).

If there is no new version, the NO_upgrade packet is transmitted to the PDA 11. The PDA 11 analyzes the received data and displays an appropriate error message upon receiving the NO_Upgrade or Error_System packet. On the other hand, when the PDA 11 receives the OK response, the actual data is received in IKB units and stored in the file system of the PDA 11 (S27). When the file transfer is completed, the procedure call is executed to execute the file. In the installation process, the existing program is forcibly terminated and the program is executed again when the installation is completed (S29).

Thereafter, the searching, status monitoring, alarming, and control processes for the repeaters are performed. These processes will be described in parallel.

First, as a method of searching for the repeater, the user searches for the repeater using three search conditions. That is, if any one of the search conditions is entered in the direct search, the local search, the recent find list, and the like (S31), the PDA 11 queries the relay information data from the locally stored local database. And display on a list of screens which are user interfaces of the PDA 11 (S33).

In addition, if you want to perform the repeater region information query, when requesting the repeater region data information query to the mRCS 13 on the displayed screen as shown in Fig. 3 (S35), mRCS 13 is a repeater monitoring server ( The MMDB of 17) and the corresponding table are queried to receive data (S37 to S39). The mRCS 13 transmits the queried data to the PDA 11 (S41), and the received PDA 11 parses the data, makes a database, and stores the data in a local database (S43).

And, if you want to perform the relay status inquiry, as shown in Figure 4, when the user of the PDA (11) selects the repeater and clicks the "status monitoring" button (S45) mRCS key value of the repeater When requesting a query by transmitting to (13) (S47), the mRCS 13 transmits a query packet to the relay monitoring server 17 (S49), and if a response is made from the server, the responded data is mRCS (13). Responsive to (S51), the received mRCS 13 responds to the data to the PDA (11) (S53). The responded PDA 11 parses the repeater packet and displays it on a screen corresponding to the user interface of the PDA 11 (S55).

Meanwhile, in performing the relay alarm display, the PDA 11 user queries the database through the interlocking server 15 and the mRCS 13 for the relay alarm information every predetermined time to receive the relay alarm information and the relay key value. The corresponding icon corresponding to the PDA 11 user interface is displayed (S57 to S61).

As such, when grasping the state of the repeater that performs the search, status monitoring, alarm function, etc., which can be performed in parallel, the PDA 11 may have a problem or control may be performed for the repeater that requires control. Control is performed using the PDA 11. 5 is a screen displayed when the repeater control is performed. On the displayed screen, when the user of the PDA 11 inputs control input data using the user interface for the repeater, and clicks the “Control” button (S63), the received data is reprocessed into a repeater packet to generate the mRCS 13. Transmission to the repeater monitoring server 17 is carried out (S65 to S67). The repeater monitoring server 17 performs control corresponding to the control (S69) and transmits the control performance result to the repeater monitoring server 17 again (S71). The repeater monitoring server 17 transmits the control result packet to the mRCS 13 (S73), and mRCS 13 responds to the PDA 11 by judging whether the control succeeds or fails, and the PDA 11 succeeds. / Warn the user of the failure and roll back the program (S75).

When the control process is performed, the control history management is performed by the mRCS 13, and the mRCS 13 directly generates the history data in the interlocking server 15 database (S77). In the repeater monitoring server 17 or the interlocking server 15, less work is required, and the function implementation in the mRCS 13 is much more convenient. In the PDA 11, the division process adds only one field to the server table and inserts a value in the mRCS 13.

On the other hand, the interlocking relationship between the interlocking server 15, the repeater monitoring server 17, the PDA 11, and the local database will be described schematically.

First, in the case of the interlocking server 15, the mRCS 13 brings data in association with the interlocking server 15 from the request of the PDA (11). The mRCS 13 exchanges data using the jdbc driver of the Oracle DBMS of the interlocking server 15 for interworking with the interlocking server 15. Oracle DBMS's jdbc driver is an application program interface (hereinafter referred to as “API”) for connecting to DBMS remotely using Java language.

In the case of the repeater monitoring server 17, the mRCS 13 imports data in association with the repeater monitoring server 17 from the request of the PDA 11. mRCS 13 is connected to the socket server of the repeater monitoring server 17 for interworking with the repeater monitoring server 17. In order to connect to the socket server of the repeater monitoring server 17, the repeater packet information and the repeater monitoring server 17 protocol are analyzed. The socket server of the repeater monitoring server 17 is a daemon program for interfacing the data retrieved from the SMS and CCU with the outside as a core function of the repeater monitoring server 17.

In the case of the PDA 11, the PDA 11 and the mRCS 13 perform HTTP communication. The mRCS 13 operates as a daemon, receives data required by HTTP, passes the processing to the Java language, and delivers the response processed by the Java language to the PDA 11. The J2EE engine uses Sun's Tomcat Server, and the Java language to code uses JSP.

In the case of a local database, the local database of mRCS 13 uses an Oracle server. mRCS (13) jdbc Driver for Oracle is used for database connection through main engine and Java language. DB connection pool mechanism is used for system optimization. The local database stores PDA 11 user information, session and state information.

On the other hand, in each server management, functions for managing the Tomcat server itself, which is the engine of the mRCS 13, and server connection, statistics, authentication, processor, and logging information are managed. Management allows the administrator to manage anytime, anywhere using a web browser.

The present invention is not limited to the above-described embodiments, and it will be apparent that many modifications are possible by those skilled in the art within the technical spirit of the present invention.

As described above, the repeater remote management system and its operation method using the PDA according to the present invention can overcome the time and space constraints of repeater management, can increase the work efficiency through real-time action history input, repeater database By unifying the standard information of, the reliability of the repeater management can be improved by preventing the absence of the reference information that can occur from the management by the independent database.
