Abstract

PURPOSE: A method for processing a call in occurrence of an overload in a mobile communication system is provided to prevent a call incapability state of an adjacent base station due to an excessive paging and provide an originating signal even in an overload state by first limiting a termination call, a factor having much influence in occurrence of the overload. CONSTITUTION: A base station periodically measures an occupancy rate of a CPU to check whether an overload has occurred(S21). The base station determines whether the measured occupancy rate of the CPU is above 85%(S22). If the measured occupancy rate of the CPU is below 85%, the base station regards it as a normal class and performs a normal call processing operation(S23). If the measure occupancy rate of the CPU is above 85%, the base station determines whether the measured occupancy rate is above 90%(S24). If the measured occupancy rate is less than 90%, the base station regards it as an overload minor class and reports only the overload state to a base station managing device(S25). If the occupancy rate of the CPU is above 90%, the base station determines whether the occupancy rate is above 95%(S26). If the measured occupancy rate is less than 95%, the base station regards it as an overload major class, limits a new termination call, and maintains an existing call(S27). If the measured occupancy rate of the CPU is above 95%, the base station regards it as an overload critical state, limits new termination and originating calls, and maintains only the existing call(S28).

Description

이동 통신 시스템의 기지국에서 과부하 발생시 처리 방법{method for processing at overload in base-station of mobile communication system}Method for processing at overload in base-station of mobile communication system

본 발명은 이동 통신 시스템의 기지국에서 과부하 발생시 처리하는 방법에 관한 것으로, 특히 과부하 발생시 착신호를 우선적으로 제한하는 방법에 관한 것이다.The present invention relates to a method for processing when an overload occurs in a base station of a mobile communication system, and more particularly, to a method for firstly limiting an incoming signal when an overload occurs.

도 1은 종래 이동 통신 시스템의 기지국에서 과부하 발생시 처리 과정을 나타낸다.1 illustrates a process of overloading in a base station of a conventional mobile communication system.

도 1을 참조하면, 기지국은 중앙처리장치의 점유율을 주기적으로 측정하여이를 근거로 과부하 여부를 측정한다.(S1)Referring to FIG. 1, the base station periodically measures the occupancy rate of the central processing unit, and measures whether there is an overload based on this.

그리고, 기지국은 중앙처리장치의 점유율이 85%이상인지의 여부를 판단하고,(S2) 중앙처리장치의 점유율이 85%이상이 아닌 경우 정상 등급으로 간주하여 정상 동작을 수행한다.(S3)Then, the base station determines whether or not the share of the central processing unit is more than 85% (S2), and if the share of the central processing unit is not more than 85% is regarded as a normal rating and performs a normal operation (S3).

한편, 기지국은 중앙처리장치의 점유율이 85%이상이면, 중앙처리장치의 점유율이 90%이상인지의 여부를 판단한다.(S4)On the other hand, if the share of the central processing unit is more than 85%, the base station determines whether or not the share of the central processing unit is more than 90% (S4).

기지국은 중앙처리장치의 점유율이 90%이상이 아닌 경우 과부하 최소 등급으로 간주하여 기지국 관리 장치로 과부하 상태만을 보고한다.(S5)If the base station is not more than 90% occupancy of the central processing unit is considered as the minimum overload class and reports only the overload status to the base station management device (S5).

한편, 기지국은 중앙처리장치의 점유율이 90%이상이면, 중앙처리장치의 점유율이 95%이상인지의 여부를 판단한다.(S6)On the other hand, if the share of the central processing unit is 90% or more, the base station determines whether the share of the central processing unit is 95% or more.

기지국은 중앙처리장치의 점유율이 95%이상이 아닌 경우 과부하 최대 등급으로 간주하여 신규 발신호를 제한하고, 기존 호를 유지시킨다.(S7)If the share of the central processing unit is not more than 95%, the base station considers the maximum overload rating to limit the new call signal and maintain the existing call.

한편, 기지국은 중앙처리장치의 점유율이 95%이상이면, 과부하 위기 등급으로 간주하여 신규 착발신호를 모두 제한하고, 기존 호만을 유지시킨다.(S8)On the other hand, the base station, if the share of the central processing unit is more than 95%, it is regarded as the overload crisis class, limiting all new initiation signals, and maintains only the existing call (S8).

이와 같이, 종래 이동 통신 시스템의 기지국은 과부하 발생시 먼저 발신호를 제어하고, 계속해서 과부하가 높아지면 이후에 착신호까지 제한한다. 하지만, 이러한 경우 부하 발생의 원인이 과도한 페이징(paging)에 의한 것이라면, 페이징 응답에 실패하는 횟수가 많아지게 되고, 이는 인접 기지국까지 영향을 미치게 되어 여러 기지국이 과부하에 의한 호 제한 상태에 빠지게 되는 문제점이 발생한다.As such, the base station of the conventional mobile communication system first controls the outgoing signal when an overload occurs, and subsequently limits the incoming call when the overload becomes high. However, in this case, if the cause of the load is caused by excessive paging, the number of times that the paging response fails is increased, which affects the neighboring base stations, causing various base stations to fall into the call limit state due to the overload. This happens.

따라서, 본 발명의 목적은 이동 통신 시스템의 기지국에서 과부하 발생시 호 자원을 효율적으로 관리하기 위한 호 처리 방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a call processing method for efficiently managing call resources when an overload occurs in a base station of a mobile communication system.

본 발명의 다른 목적은 이동 통신 시스템의 기지국에서 과부하 발생시 착신호를 우선적으로 제한하는 방법을 제공함에 있다.Another object of the present invention is to provide a method of preferentially limiting an incoming signal when an overload occurs in a base station of a mobile communication system.

도 1은 종래 이동 통신 시스템의 기지국에서 과부하 발생시 처리하는 과정을 나타내는 도면.1 is a diagram illustrating a process of processing when an overload occurs in a base station of a conventional mobile communication system.

도 2는 본 발명에 따른 이동 통신 시스템의 기지국에서 과부하 발생시 처리하는 과정을 나타내는 도면.2 is a diagram illustrating a process of processing when an overload occurs in a base station of a mobile communication system according to the present invention.

이러한 목적들을 달성하기 위한 본 발명은 중앙처리장치의 점유율을 주기적으로 체크하여 기지국의 과부하 발생시 착신호부터 우선적으로 제한하는 것을 특징으로 한다.The present invention for achieving the above objects is characterized in that by periodically checking the occupancy of the central processing unit to limit the incoming signal first when an overload occurs in the base station.

본 발명에 따른 이동 통신 시스템의 기지국에서는 하기 표 1에 기재된 바와 같이 중앙처리장치의 점유율에 따라 과부하 등급을 부여하고, 상기 과부하 등급에 따라 착발신호를 제한한다.In the base station of the mobile communication system according to the present invention, as shown in Table 1 below, the overload rating is assigned according to the occupancy of the central processing unit, and the incident signal is limited according to the overload rating.

이하 본 발명을 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 이동 통신 시스템의 기지국에서 과부하 발생시 처리 과정을 나타낸다.2 shows a processing procedure when an overload occurs in a base station of a mobile communication system according to the present invention.

도 2를 참조하면, 기지국은 중앙처리장치의 점유율을 주기적으로 측정하여 과부하 발생 여부를 체크한다.(S21)2, the base station periodically checks the occupancy rate of the central processing unit to check whether or not an overload occurs.

그리고, 기지국은 상기 측정된 중앙처리장치의 점유율이 85%이상인지의 여부를 판단하고,(S22) 상기 측정된 중앙처리장치의 점유율이 85%이상이 아닌 경우 과부하 상태가 아닌 정상(NORMAL) 등급으로 간주하여 정상적인 호 처리 동작을 수행한다.(S23)Then, the base station determines whether the measured share of the central processing unit is more than 85% (S22), if the measured share of the central processing unit is not more than 85%, the normal (NORMAL) grade not overload In step S23, normal call processing is performed.

한편, 기지국은 상기 측정된 중앙처리장치의 점유율이 85%이상인 것으로 판단되면, 상기 측정된 중앙처리장치의 점유율이 90%이상인지의 여부를 판단한다.(S24)On the other hand, if the base station determines that the measured share of the central processing unit is more than 85%, it determines whether or not the measured share of the central processing unit is more than 90% (S24).

기지국은 상기 측정된 중앙처리장치의 점유율이 90%이상이 아닌 경우 과부하 최소(MINOR) 등급으로 간주하여 과부하 발생 상태만을 기지국 관리 장치로 보고한다.(S25)If the measured share of the central processing unit is not more than 90%, the base station considers the minimum overload (MINOR) level and reports only the overload state to the base station management device.

한편, 기지국은 상기 측정된 중앙처리장치의 점유율이 90%이상인 것으로 판단되면, 상기 측정된 중앙처리장치의 점유율이 95%이상인지의 여부를 판단한다.(S26)On the other hand, if the base station determines that the measured share of the central processing unit is more than 90%, the base station determines whether or not the measured share of the central processing unit is more than 95% (S26).

기지국은 상기 측정된 중앙처리장치의 점유율이 95%이상이 아닌 경우 과부하 최대(MAJOR) 등급으로 간주하여 신규 착신호를 우선적으로 제한하고, 기존 호를 유지시킨다.(S27) 즉, 본 발명에 따른 기지국은 일정 등급 이상의 과부하 발생시 신규 착신호를 먼저 제한하고, 신규 발신호를 허용한다. 이와 같이, 본 발명에 따른 기지국은 과도한 페이징으로 인해 과부하 발생시 신규 착신호를 먼저 제한하고, 발신호를 계속 허용하므로 호 자원을 효율적으로 사용할 수 있다.If the measured share of the central processing unit is not more than 95%, the base station regards it as an overload maximum (MAJOR) class and preferentially restricts new incoming calls and maintains existing calls. (S27) That is, according to the present invention. The base station first limits the new incoming signal when overload occurs over a certain level, and allows the new outgoing signal. As described above, the base station according to the present invention first limits the new incoming signal when overload occurs due to excessive paging, and allows the outgoing signal to be used efficiently.

한편, 기지국은 상기 측정된 중앙처리장치의 점유율이 95%이상인 것으로 판단되면, 과부하 위기(CRITICAL) 상태로 간주하여 신규 착발신호를 모두 제한하고, 기존 호만을 유지시킨다.(S28)On the other hand, if the base station determines that the measured share of the central processing unit is more than 95%, it considers the CRITICAL state to limit all the new start signal, and maintains only the existing call (S28).

상술한 바와 같이 본 발명은 이동 통신 시스템의 기지국에서 과부하 발생시 더 많은 영향을 미치는 요소인 착신호를 먼저 제한함으로써 과도한 페이징으로 인하여 인접 기지국까지 호 불능 상태에 빠지는 것을 방지할 수 있다.As described above, according to the present invention, by limiting an incoming call, which is a factor that affects more when an overload occurs in the base station of the mobile communication system, it is possible to prevent the terminal from falling into a disabled state due to excessive paging.

또한, 본 발명은 이동 통신 시스템의 기지국에서 과다한 페이징으로 인한 과부하 발생시 착신호를 우선적으로 제한하므로써 기지국이 과부하 상태이더라도 발신호를 제공해줄 수 있다.In addition, the present invention can provide an outgoing signal even when the base station is overloaded by first limiting an incoming signal when an overload occurs due to excessive paging in the base station of the mobile communication system.

게다가, 본 발명은 이동 통신 시스템의 기지국에서 과부하 발생시 과부하에 가장 많은 영향을 미치는 요소인 페이징 요소인 착신호를 우선적으로 제어함으로써 효율적으로 과부하를 제어할 수 있다.In addition, the present invention can efficiently control overload by preferentially controlling an incoming signal, which is a paging element, which is a factor that most affects overload when an overload occurs in a base station of a mobile communication system.
