In DEVICE_BASED_PRICING project,Bharti wanted to send special offers to those subscibers which have 4G compatable handsets.

In NRT DATA 20MB, Bharti wanted to know those customers whose last one hour of data usage is greater than 20MB and how it is impacting Bharti, what is there sentiments for Bharti and competitors, Text analytics for NRT Campaigning and Report purposes.

In SGSN,GGSN Project we have developed an application which is responsible for converting binary data to human readable format. The binary data could be structured or un-structured. In this, we have done some scripting also for logging and error handling so that if application crashes (file system full or System shut down) due to any reason, It should be logged and tracked so that processing can be start from there, where it is crashed.

In HLR PARSER project,we have developed an HLR(HOME LOCATION REGISTER )Parser which is responsible for coverting binary data to human readable format. The binary data could be structured or un-structured.In this we found those subscribers raw CDR’S whose entry in Home Location Register .

In MSC Project ,we have deployed an application which is responsible forcall data record in terms of sms,call and data.
