Mobile Data Charging System and Roam Monitor Controller

Environment: UNIX, C++, STL, JAVA, SVN.

MDCE is a mobile data charging system, that keeps track of the user’s data usage and based on the configured rate plan, rates subscriber’s data usage. The product is already deployed in Maxis (Malaysia). Involved in providing maintenance support to the product.

Roam Monitor Controller is a spinoff of the MDCE. RMC is basically to alert the operator / subscriber (in near real-time) of their high usage or high money spent to control the mobile expense while roaming. In other words it is a solution to prevent customer bill shocks. RMC uses SMPP/ SMTP/ SNMP to alert the operator / subscriber and Oracle DB to log the alerts sent.

•Involved in supporting MDCE (in C++).
•Involved in gathering requirements and designing for RMC.
•Writing various functions and classes as required in RMC.
•Involved in development of RMC product which rates subscriber’s usage and keeps track of subscriber’s usage and amount spent in oracle DB and on crossing the threshold (set by operator/ subscriber) , triggers Alert Module to generate an alert.
•Responsible for developing the alert module (in JAVA) single handedly, which on receiving trigger from RMC, generates the required (smpp/ smtp/ snmp/ file/ db) alert to subscriber / operator. Used RMI, Mutithreading, JMS and JPF in AM development. AM module is now deployed with MDCE in maxis for generating SMS to the subscriber. Enhancements are still in process for other plugins (SMTP/SNMP).

•Involved in development of SOAP APIs for Roamware to use RMC as rating Engine.
