Objective : The project is to provide features to support LTE real time data charging solution implementation over ICC 5.6.
Certain ICC 5.8 features will be back ported and some new features will be implemented in ICC 5.6.
Some of the features are: -
* Support of interoperability with Diameter Gy / Ro 3GPP TS32.299 release 10 in IMS and PS Domain. ;
* Handling the RAT_TYPE change trigger ;
* Introduction of LTE CELL ID. i.e. to determine the origin subscriber's geographic location information in the LTE network for cell based zoning.
* Record received IMEI in CDR. to include an additional parameter ``IMEI number'' in the CDR.
As a part of Professional services team my objective is to plan the ATP strategy and perform acceptance tests. My objective was also to deliver the various documents like acceptance test plans, MOPs, configuration document... etc.
Role : * Perform acceptance tests.
* Interaction with Customer Support Manager and customer for requirement clarification.
* Preparations of Solution Definition Document as well as call flow documents required for new features implementation.
* Design and develop Software Upgrade MOPs for ICC application on 5.6
* Create, update and review of ICC Configuration Document based on the new LTE features
* Create, update and review of 1st call & Basic Functional test Document.
* Create, update and review of new feature Acceptance Test Plan documents based on Feature Description Document (FDD) from ALU ICC R&D team.

Objective : The Alcatel-Lucent 8642 ICC-CRE product enables service providers to use Convergent Rating Engine for pre-paid and post paid services (e.g. Refillable and non- refillable pre-paid Calling card, postpaid service and their billing). There were around 100+ new requirements that were different from the generic ICC product. All these requirements were implemented by customizing the generic ICC-CRE product and were delivered in four different phases (Phase I, II, III, IV). This was a very long duration project and I was involved since requirement analysis to GO-LIVE. Current work profile involves interaction with Systems team to help them in preparing detailed architecture design of the features. Implementation of features as per the design. Involved in production/deployment.
