Background

  • The main network elements in the Mobile Packet Switching network are the SGSN/MME and GGSN/PGW in a hybrid UMTS/LTE network.
  • These in collaboration with other core network elements provide the data service for the customers.
  • A good service provision depends on the health of these network elements, hence it is crucial to monitor the alarms.
  • The 'PS Network Alarms' application is a handy tool for this important network operator activity.

Data Source

  • For this application I have selected the SGSN/MME network elements.
  • The alarms are collected from three SGSNMME nodes.
  • Here is the summary:
ps <- read.csv("PS Alarms.csv")
ps$Alarm.ID <- as.factor(ps$Alarm.ID)
psd <- split(ps, ps$Alarm.Source)
summary(ps)

##   Alarm.ID                 Alarm.Source 
##  10254:  29   SGSNMME_01.HW.NF.AA:1976  
##  10334: 205   SGSNMME_02.HW.MW.AA:1712  
##  11608: 908   SGSNMME_03.HW.KK.AA:1542  
##  11609:2108                             
##  12621:  26                             
##  14001:1954

Graphic Comparison

Using the app, we can compare which alarms are more prominent on which nodes.

old.par <- par(mfrow=c(1, 3))
plot(psd[[1]]$Alarm.ID, main="Alarms on SGSNMME 01",xlab='Alarm ID', ylab='Count', ylim=c(0,900))
plot(psd[[2]]$Alarm.ID, main="Alarms on SGSNMME 02",xlab='Alarm ID', ylab='Count', ylim=c(0,900))
plot(psd[[3]]$Alarm.ID, main="Alarms on SGSNMME 03",xlab='Alarm ID', ylab='Count', ylim=c(0,900))

The APP

On the PS Network alarms application you have a dropdown menu option for selecting anyone of the nodes to display the alarms including the option to see all the alarms on all of the nodes, as below.

plot(ps$Alarm.ID, main="Alarms on all SGSNMME's", xlab='Alarm ID', ylab='Count', ylim=c(0,2000))
