1 is an exemplary configuration diagram of a mobile communication system to which the present invention is applied and is an exemplary configuration diagram of a mobile communication system for automatically changing switch time information using a mobile application unit (MAP) operation message.

Any of the plurality of mobile communication exchanges 100 shown in FIG. 1 can be set as a master or slave exchange by changing only database values.

The mobile communication switch 100 is in charge of a function of interworking with another mobile communication switch 100 in order to process a water receiving request from a mobile communication terminal, and inquiring a subscriber to the home location register 200. When the mobile communication terminal starts and ends a call, the exchange 100 which sets the first call is in charge of charging. At this time, the charging time recorded by the switch 100 is based on the time information held by the switch 100.

The accessory system 110 includes a voice activated dialing (VAD) system, a short message service system (SMS), a virtual private network (VPN) system, and a prepaid card service system (PPS). Pre-paid Service System, etc., each of which receives the call from the mobile communication switch 100 when the voice recognition service call, short message service call, virtual private network service call, prepaid card service call occurs, You will leave a billing record. Of course, the charge record here is duplicated with the charge record generated in the mobile communication switch 100, it is also possible to exclude the charges generated in the mobile communication switch 100 in accordance with the policy of the carrier. For this purpose, billing records should not be visually duplicated.

The home location register 200 is a medium-class computer mainly performing a subscriber information processing device function. The home location register 200 is classified into four types, a network access device, a subscriber database, and an operation management device.

Signaling Transfer Point (Signaling Transfer Point) 210 is a dedicated exchange that is responsible only for the control signal relay used for the control of the call. Therefore, in most switching systems in which the signal relay switch 210 is installed, the MAP Operation Message passes through the signal relay switch 210.

FIG. 2 is a flowchart illustrating a method for adjusting a switch time using a reserved MAP operation message according to the present invention.

As shown in FIG. 1 above, all exchanges drive the time adjustment process at the latest time (301). Since Master or Slave is not fixed and can be changed in the database, the processes running in all exchanges are the same process, and the process itself has no distinction between Master or Slave. As a result of the time reconciliation process inquiring about the other exchange, if the other exchange is set as a slave, it becomes a master that sends time information to that exchange, and if the other exchange is a master, It is the position to receive the adjustment information.

Therefore, it is checked whether the own switch (or another switch) is set as a slave (Slave) after the process starts (302).

As a result of the check 302, all of the exchanges set as the master search for other exchange data and transmit the MAP Operation Message to the exchanges set as the slave (Slave) ( 303).

On the other hand, after the check result 302, the exchanges set as slaves receive the MAP Operation Message from the other exchanges, and then retrieve the counterpart exchange data stored in the counterparts. Check if it is set as its master (304).

As a result of the check 304, if the other exchange is not set as a master, it informs that there is an error in setting a master / slave to a terminal to which an output message is output (305).

On the other hand, if the switch that sent the time adjustment mobile application part operation message is set as its master, the check result 304 compares its own time information with the time information of the received mobile application part operation message. (306).

As a result of the comparison 306, if the time difference is smaller than the allowable error, it is output to the output terminal that the error is not corrected because it is smaller than the allowable error (307).

On the other hand, when the comparison result 306, when the time difference is greater than the tolerance, the slave exchange corrects its exchange time with the time sent from the master exchange (308). After correction (308), an output message is output (309) to the terminal for the operator to recognize that the correction has been made.

This process may be performed every day, and the work execution schedule may be managed by the work schedule of the exchange, and the work execution schedule may be set by the operator by managing the operation data of the exchange.

In order to perform the present invention as described above, an item is configured in advance in a database of an exchange so as to set a master and a slave. In addition, the master exchange drives the process according to the set data to generate the mobile application operation message according to the work schedule and builds the process to transmit to the slave exchange. At this time, use an unused preliminary mobile application operation message. Meanwhile, the slave exchange establishes a process of the exchange to correct its own time information according to the received time information.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

The present invention as described above, by using the reserved operation code (Reserved Operation Code) that is reserved for future use of the MAP operation code (MAP Operation Code) by setting the time of all exchanges to the same, the redundant charging of the exchange Minimizing and reducing the cost of connecting an input / output port and a time coordination server and adding a server for each exchange compared to the conventional method.

That is, in the present invention, by adjusting the time using the remaining MAP Operation Code, which is not used in the present invention, a signal link is configured with another exchange when the exchange is installed, and the time information is updated every day. By transmitting at the shortest time, there is an effect that the time information of the exchange can be easily and automatically matched.
