Ericsson has always strived for the technology leadership in its offering by designing products based on the latest technology. Going ahead with a similar thought it started exploring an idea of running a mobile core application using a Simplified Infrastructure (SI) to eventually enable the Cloud based solutions. But in order to run these type of applications in the Cloud, the in-service performance provided by such a SI should be the same as the native infrastructure in order to maintain the mobile core application’s QoS. "High availability" of the infrastructure is one of the measure of the ISP and from the ISP point of view, such a migration would be considered feasible only if the SI is able to maintain the same level of availability as provided by the native infrastructure solution without bringing in any major architecture changes within the SI. Hence this master thesis project investigates the feasibility of achieving the same availability as before if the mobile core application is to be migrated from the native infrastructure to the SI. Such a feasibility exploration was the very first attempt with respect to the SI within Ericsson, which was executed through this master thesis project. In order to achieve the goal of this thesis project a detailed system study was carried out, which focused on the native infrastructure architecture, how it was maintaining the "high availability" and how it differed from the SI. In the end, it was possible to confirm that the level of availability of infrastructure services as provided through the SI will be higher than the native infrastructure after the migration if the proposed suggestions of this master thesis project are implemented successfully. These implementations also do not change the architecture of the SI in any major way. The end results of this thesis project were also highly appreciated by Ericsson and are now part of thedevelopment plan for next mobile core infrastructure solution at Ericsson.
