| Abstract | At the present, with the development of ETL Mobile networks, Lao P.D.R, demands of connection between ETL Mobile and service providers, existing and new network are increasing more and more. Therefore, traffic measurement and analysis are necessary and important for network management and operation. This research studies the behaviours of traffic between GSM and providers (fixed, mobile and international), GSM and three media gateways of NGN network, NGN and providers, NGN and BSCs of ETL Mobile network. The research also studies signalling link traffic between CS and HLR, CS and SCP. The GPRS behaviour is also considered like attempts, failure and success. The analysis consists of statistic number of calls, traffic profile, calls success ratio, calls failure ratio, calls answer ratio, mobile subscriber behaviour, holding time and conversation time. The links load and failure ratio of GPRS (reject network behaviour and reject subscriber behaviour) attached and activate PDP also considered. The results of traffic measurement show that number of calls between GSM and LTC Mobile1 is the highest (44.47% and 37.16% of from and to GSM) because of larger network and higher subscriber density as compared to Tigo (34.24% and 20.56% of from and to GSM) which is the lowest. Same as reasons above, Startel (24.42% and 27.68% of from and to NGN) is lower than LTC Mobile2 in case of NGN network. Beside that, with population density, larger network and wide area of coverage of MGW_VTE, number of calls between GSM and MGW_VTE is larger than other two media gateways. Traffic between mobile to mobile almost rise up the highest peak value at 20:00 PM, in the contrary, traffic between mobile and fixed providers rise up and get the highest value at working time 10:00 AM. The traffic profile indicated that busy hour happened at 19:00 – 20:00 PM every day. Traffic of working days is always higher than Saturday and Sunday. Calls failure ratio from providers and BSCs to NGN is higher than from NGN to provider and BSCs, 9.97% and 1.70% respectively. With low charging rate as same company, almost ETL’s fixed subscribers are provided for government officer and no charge. The average holding time and duration of conversation time from ETLF1 to GSM is longer than other mobile and fixed providers, 28.2 minutes and 18.7 minutes of holding time and conversation time respectively. Only 2.3 minutes and 1.8 minutes of mean from GSM to ETLF1 because charging it taking place. The signalling links load (SCP and CS, HLR and CS) are similar during a week with average about 20%, and links down rate is very small with below 0.08%. The percentage of GPRS attempt and success are not much different and failure rate also not much with different in cases of network and subscriber behaviour. |
