Abstract

PURPOSE: A data transfer interrupting method in a digital mobile communication system is provided to send only command, which has to be transferred, according to significant degree at overloading and to change degree setting for a corresponding command through a data base. CONSTITUTION: In a data transfer interrupting method in a digital mobile communication system, if a base station manager starts to drive, the degree according to significant degree of each command is set in a data base storing part, and whether a command is associated with a base transceiver subsystem or a base station controller processor(S1-S4). If not, whether the command is a degree changing command is confirmed. If so, the procedure goes to the step(S2). If not, the function corresponding to the command is performed(S5). If the command is associated therewith in the step(S4), a command significant degree stored in the data base storing part is compared. Whether the degree is over the G1 degree of being always performed, is judged. If so, the corresponding command is performed(S6,S13). If the degree is not the G1 degree, whether a CPU state of the processor is an overload state is judged. If the CPU state is less than a threshold value(T1) of a minimum degree, the corresponding command is performed. If the CPU state is higher than the threshold value(T1), whether the CPU state is over a maximum threshold value(T2) is judged(S8). If so, whether the CPU state is over an emergency threshold value(T3) is judged(S9). If below the emergency threshold value(T3), whether the significant degree is over a G2 degree of being performed even at an overload state is judged. If so, a corresponding command is performed(S11,S13).

Description

Data transmission automatic breaking method of the digital mobile communication system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital mobile communication system, and in particular, classifies classes according to necessity and importance to be transmitted in case of CPU overload of a base transceiver station (BTS) or a base station controller (BSC). And less important data is related to a method for automatically blocking data transmission in a digital mobile communication system, which cuts down the transmission, thereby reducing the load on the base station or the control station and has a minimal effect on the system.

Conventional base station manager (BSM) transmits all message signals without filtration that increase the load of the system without being important for reasons such as operator commands. It was.

Therefore, if the BSM sends a lot of message signals for reasons such as an operator command when the base station or the control station is overloaded, the load is added and the class is increased due to the weighted load. Delayed return to steady state degraded the normal operation of the system

In addition, in the overload control state of the base station or the control station, there is a problem in that the efficiency of the system is lowered, such as the call resource is not set for a sustained time as the overload condition continues to prevent additional call setup according to the overload class.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object of the present invention is to classify an operator command with a message signal of an operator command among data sent from a BSM to a base station or a control station. Data of the digital mobile communication system that transmits only the command that must be transmitted according to the importance of the command in case of overload and allows the operator to change the rating setting through the database if the operator wants to change the rating setting for the command. The purpose is to provide an automatic transmission blocking method.

In order to achieve the above object, the present invention sets a class according to the importance of each command at the start of the operation of the BSM, and determines whether the operator command is a command related to a base station or a control station processor. If it is, the class is reset to the changed contents. If it is a command other than the above, the corresponding function is executed for the command. In the case of the command related to the control station or the base station, the command importance level stored in the database is compared and it can be always performed or overloaded. It is determined whether the status is above the minimum threshold T1, above the minimum threshold T2, or above the crisis threshold T3. In case of "Yes", it indicates the instruction hold and the corresponding overload class of the base station or the control station. Characterized in that it performs a command.

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

1 is a block diagram of the present invention, a database storage unit (1) for storing the corresponding grade of the operator command and the contents of the overload grade reported by the control station and the base station, and the command is provided by directly interfaced with the operator and the screen result The operator interface screen processing unit 3 for outputting the operator, the operator command processing unit 2 for generating and interpreting the command contents generated by the operator when the operator interface screen processing unit 3 executes the command, and the operator command processing unit 2 The operator command execution unit (4) generated according to the interpretation and performing the actual necessary command contents, and the request message signal is received by the operator command execution unit (4) according to the requirements in the operator command and report the result The main consists of a base station (or control station) processor 5.

The present invention configured as described above will be described in detail with reference to FIG. 2, which is a flowchart of command processing according to the overload class and command importance of a base station and a control station when performing a command class setting and an operator command of a BSM of a digital mobile communication system.

That is, when the BSM starts to drive, the database storage unit 1 sets the class according to the importance of each command and checks whether the operator performs the command related to the base station or the control station processor when the operator performs the command (steps S1-S4).

Here, if it is not a command related to the base station or the control station, check whether it is an operator command importance level change command, and if it is a command related to a class change, go back to step S2 and set the class again to the changed content. (Step S5).

That is, whether or not to process the operator command is determined by the instruction critical level stored in the database storage unit 1 when the BSM is driven and reported from the base station or the control station when an overload occurs, and the operator command critical class is implemented to be changeable by the operator command.

In the case of the command related to the control station or the base station in step S4, the instruction importance level stored in the database storage unit 1 is compared.

If it is determined that the instruction importance level is always higher than G1 that can be performed, the corresponding command is executed when it is G1, which is the highest priority level that should be performed in any case (steps S6 and S13).

However, if it is not the G1 level, which is the highest priority instruction level to be performed in any case in step S6, it is determined whether the CPU state of the base station or the control station processor is overloaded.

That is, if the threshold value of the minimum level, the minimum level of overload, as in step S7 is smaller than T1, the command is executed because it is not yet overloaded.

However, if the threshold of the minimum grade is greater than T1, it is determined whether the overload condition is greater than or equal to the maximum threshold T2 (step S8).

If the overload condition is less than or equal to the maximum threshold T2, it is determined whether the command importance level is greater than or equal to G3 that can be performed even in the least overload class. A message about the appropriate overload rating of the system is output to the operator so that the operator can easily cope with this situation.

If the operator must execute this command in this situation, the operator command importance level change command in step S3 is executed to change the level to G3 or higher and set the level again as in the step S2.

On the other hand, if the current overload rating is greater than or equal to the maximum threshold T2 in step S8, it is determined whether the overload condition is above the crisis threshold T3 (step S9).

If the overload condition is below the critical threshold T3, it is determined whether the instruction importance level is the G2 level or more that can be performed even at the maximum overload level, and if the level is more than that, the corresponding command is executed (steps S11 and S13).

However, if the instruction importance level is less than G2, the command output message and the message about the corresponding overload class of the base station or the control station processing the command is output to the operator (step S12).

In this case, if the operator must execute this command in this situation, perform the operator command importance level change command in step S3 to change the level to G1 or higher that can be executed unconditionally and reset the class as in step S2, and then execute the command. do.

As described above, the present invention considers the importance of the message and the overload state that many message signals are transmitted by the operator command without considering the BSM at all even when the overload state is previously reported to the base station or the control station. By deciding whether or not to transmit, unnecessary processors added to the base station or control station can be reduced as much as possible, and the overload rating can be prevented from being raised or lasting longer.

In addition, if the range of additional call establishment rejection is determined according to the overload class in the overload control state, the increase of call resource utilization is increased by reducing the duration of the overload state by reducing the additional call setup rejection range by preventing the increase of the overload class. There is an effect that can accommodate the subscriber.
