Description

一种实现实时监控告警的通信系统及其方法
技术领域
本发明涉及一种通信系统及其控制方法,尤其涉及一种可以实现实时监控告警的通信系统及其方法。
背景技术
现代通信系统的发展,给人们生活带来极大的方便。为了保证通信系统的正常运行,技术人员采取了各种保障措施。如针对通信系统发生故障时向上级管理服务器上报告警或提示信息。这种告警信息在被关注事件发生时或被关注对象状态发生变化时送出,是以状态变迁作为发送告警信息的基础,例如有非法用户使用通信系统或传输链路由正常状态变为故障状态时,发送告警信息。当前这种发送告警信息的方法无法满足通信系统或传输链路处于正常状态下,只是某个监控指标达到了监控值时需要发送告警信息的需求,例如需要将某个阶段的话务量达到一定的数量级后就送出实时信息,这是无法实现的。
另外,对于目前的通信系统,各地区在使用过程中情况差异很大,不同的地区要求不尽相同,如有些电信局需要在某个话务指标达到0.5时就希望得到相关的告警信息,而另外的电信局,则希望该话务指标达到0.7以上时再发送告警信息;有的用户希望半小时的话务指标达到一定值时就发送告警信息,有的用户则关注的是一个小时的结果,还有其他的各种各样的需求,但目前提供的通信系统无法满足这些可以在告警周期和告警阈值都进行定制的需求。
发明内容
本发明提供一种实现实时监控告警的通信系统及其方法,利用通信系统中的话务统计功能,由用户定制告警的信息类型和告警的周期、阈值,来实时对通信网络进行监控。
本发明所述的通信系统,在系统服务器中进一步包括了监控信息储存模块、话务统计定制模块和告警信息发送模块;
所述监控信息储存模块用于存储监控信息,所述监控信息包括监控对象、监控时间、监控周期、监控阈值等信息;
所述话务统计定制模块用于根据上述存储的监控信息,制定话务统计任务,即制定针对被监控对象的话务统计时间、话务统计周期,并执行话务统计,生成话务统计结果;
所述告警信息发送模块用于将上述话务统计结果与监控阈值比较,当话务统计结果超过监控阈值,或话务统计结果低于监控阈值,或话务统计结果介于监控阈值范围内时,发送告警信息。
本发明还提供了一种通信系统中实现实时监控告警的方法,其步骤包括:
步骤一,在通信系统服务器中储存监控对象、监控时间、监控周期、监控阈值等信息;
步骤二,根据上述储存的监控信息,制定话务统计任务,执行话务统计,生成话务统计结果;
步骤三,将上述话务统计结果与监控阈值比较,当话务统计结果超过监控阈值,或话务统计结果低于监控阈值,或话务统计结果介于监控阈值范围内时,发送告警信息。
上述实现实时监控告警方法的步骤二中,所述的制定话务统计任务是指根据系统服务器中存储的监控信息,即监控对象、监控时间和监控周期,来制定针对被监控对象的话务统计时间和话务统计周期。
本发明中还可对通信系统中的多个对象同时进行监控,其方法为:在通信系统服务器中储存对应多个监控对象的监控时间、监控周期和监控阈值等信息,并根据这些监控信息制定多个话务统计任务,通信系统服务器同时执行多个话务统计任务,生成话务统计结果,当话务统计结果超过监控阈值,或话务统计结果低于监控阈值,或话务统计结果介于监控阈值范围内时,发送告警信息。
本发明通过在通信系统服务器中储存监控信息,制定针对监控对象的话务统计任务,既可以对一个对象进行实时监控,也可以对多个对象同时进行监控,同时还可制定针对每个不同监控对象的不同的监控时间、监控周期、监控阈值,改变了现有技术中通信系统对监控对象的监控方式无法满足个性化定制的弊端,做到了对不同监控对象的灵活实时监控。

具体实施方式
本发明中利用了现有通信系统中的话务统计功能,在现有的可以对话务进行周期性统计的功能的基础上,通过定制监控信息与话务统计任务,并将话务统计结果与定制的监控信息相比较,来发现是否存在需要进行告警的监控对象,如存在则进行告警,否则,按定制的监控周期再进行监控。
下面结合说明书附图对本发明做进一步说明。
如说明书附图1所示,本发明所述的通信系统服务器中增加设置了监控信息储存模块、话务统计定制模块和告警信息发送模块。
如说明书附图2所示,本发明对一个监控对象进行实时监控的过程如下:
步骤101,在通信系统服务器中储存监控信息,包括欲进行监控的监控对象,开始进行监控的监控时间,进行监控的时间周期,以及针对该监控对象的监控阈值,例如监控对象为某7号信令链路的负荷,监控时间为9月7日至10月7日,监控周期为半小时,监控阈值为0.7,即对该7号信令链路的负荷在9月7日至10月7日期间内每半小时进行一次话务统计,如果话务统计的结果即平均负荷超过0.7时就发送告警信息;
步骤102,根据上述通信系统中储存的监控信息,制定话务统计任务,即根据监控对象、监控时间和监控周期等信息,来制定针对被监控对象的话务统计时间和话务统计周期的任务;话务统计任务制定完毕,通信系统执行话务统计任务,并生成话务统计结果,例如根据上述的对该7号信令链路的监控信息,制定通信系统在9月7日至10月7日期间内每半小时进行一次话务统计,并生成话务统计结果;
步骤103,通信系统将话务统计结果与服务器中储存的监控阈值进行比较,看话务统计结果是否超过设定的监控阈值,如超过,则执行步骤104,否则,执行步骤102,按设定的监控周期继续进行话务统计,并生成话务统计结果;例如话务统计结果为该7号信令链路的平均负荷为0.8,超过了设定的监控阈值0.7,则执行步骤104;如果话务统计结果为该7号信令链路的平均负荷为0.6,未超过设定的监控阈值0.7,则继续对该7号信令链路进行半小时的话务统计,并生成话务统计结果;
步骤104,发送告警信息。
上述方法中所述的监控周期,是在设定的时间范围内进行话务统计,并生成话务统计结果的时间间隔。
上述方法中,通信系统储存的监控信息,即监控对象、监控时间、监控周期、监控阈值等信息,具体储存在监控信息储存模块中。
上述方法中,根据监控信息制定话务统计任务,并执行话务统计任务,生成话务统计结果,具体可由通信系统中的话务统计定制模块来实现。
上述方法中,将话务统计结果与服务器中储存的告警阈值进行比较,当话务统计结果超过设定的监控阈值时发送告警信息,具体可由通信系统中的告警信息发送模块来实现。
上述方法中,监控对象为某7号信令链路的负荷,也可以为其他的监控项,如发送消息数、接收消息数等等。
上述方法中,设定了在监控时间为9月7日至10月7日期间内,监控周期为半小时,监控阈值为0.7,此处的监控阈值也可以设置为在9月7日至10月7日期间内为不同的数值,即9月7日至9月22日为0.7,9月23日至10月7日为0.8,当被监控的该7号信令链路负荷达到对应的阈值时,发出告警消息。
上述实施例是对7号信令链路的负荷在9月7日至10月7日期间内每半小时进行一次话务统计,如果话务统计的结果即平均负荷超过0.7时就发送告警信息;也可以在话务统计的结果达到监控阈值的其他情况下发送告警信息,即话务统计的结果低于监控阈值时发送告警信息;或将监控阈值设置为一个区间值,当话务统计的结果介于监控阈值范围内时就发送告警信息,如监控阈值范围为0.6至0.8,则当平均负荷为0.7时,因负荷值位于监控阈值范围内,故发送告警信息。
通过上述方法,可以在设定的时间内按设定的时间间隔实时地将话务统计结果与设定的监控阈值相比较,如达到则发出告警信息,而不必一定要等到通信系统发生故障时才发出告警信息,这样大大提高了通信系统维护的灵活性。
本发明还可同时设定多个不同的监控信息,对多个不同的对象进行分别监控,其方法如下:
步骤201,在通信系统服务器中储存多个监控信息,包括欲进行监控的多个监控对象,开始进行监控的监控时间,进行监控的时间周期,以及针对这些监控对象的监控阈值,例如监控对象一的监控信息为7号信令链路半小时的平均负荷达到0.7时发送告警信息;监控对象二的监控信息为9月7日到10月7日所有到H信令点的所有7号信令链路1小时的平均负荷达到0.8时发送告警信息;监控对象三的监控信息为到J局点的出中继电路的2小时的每线平均话务量达到0.8时发送告警信息;
步骤202,根据上述多个监控信息,分别制定话务统计任务,并生成对应的话务统计结果;例如,针对监控对象一制定的话务统计任务为所有7号信令链路的半小时为统计周期的永久话务统计任务;针对监控对象二制定的话务统计任务为到H信令点的所有7号信令链路的9月7日到10月7日的以1小时为统计周期的话务统计任务;针对监控对象三制定的到J局点的出中继的以2小时为统计周期的话务统计任务;通信系统根据上述制定的话务统计任务,以各自对应的统计周期进行话务统计,并生成话务统计结果;
步骤203,将上述各个监控对象的话务统计结果与对应的监控信息中设定的监控阈值相比较,看是否超过设定的监控阈值,如超过,则执行步骤204,否则,重复执行步骤202,按设定的监控周期继续进行话务统计,并生成话务统计结果;例如,监控对象一的7号信令链路半小时的平均负荷大于0.7,则执行步骤204,否则,按设定的统计周期继续进行话务统计,生成话务统计结果,直至设定的监控时间结束;监控对象二在到H信令点的所有7号信令链路的9月7日到10月7日的统计时间内,如果1小时的平均负荷超过0.8,则执行步骤204,否则,按设定的统计周期继续进行话务统计,生成话务统计结果,直至设定的监控时间结束;监控对象三在到J局点的出中继电路的2小时的每线平均话务量达到0.8,则执行步骤204,否则,按设定的统计周期继续进行话务统计,生成话务统计结果,直至设定的监控时间结束;
步骤204,发送对应的告警信息。
上述方法中,对于监控对象一和监控对象三来说,对它们的监控时间是从话务统计任务制定时刻开始的,是一个永久的话务统计任务,通信系统会以对应的监控周期对其进行话务统计,实时生成话务统计结果,当满足告警信息的发送条件时,发送告警信息;而对于监控对象二来说,对它的监控只是一段时间的行为,通信系统在这段设定的监控时间内对其进行话务统计,实时生成话务统计结果,当满足告警信息的发送条件时,发送告警信息,而在设定的监控时间之外时,通信系统无相应的话务统计结果生成。
上述实施例中,也可以设定话务统计结果与监控阈值比较的其他情况,即告警信息不仅仅在话务统计结果超过监控阈值时发送,也可以在话务统计结果低于监控阈值时发送,或是在话务统计结果介于监控阈值范围内发送,如监控对象一,即7号信令链路的监控阈值为0.7,则当7号信令链路半小时的平均负荷低于0.7时发送告警信息;或对监控对象一,即7号信令链路的监控阈值设置为0.6至0.8,则当7号信令链路半小时的平均负荷到达0.7时,因其处于监控阈值范围内,故发送告警信息。
由此可见,本发明可以根据用户的需求,对通信系统的运行状态的结果进行统计监控并自动发送相应的告警信息,有效地提高了系统运行维护的效率。
