IoT/M2M Network Capacity Planning Analytics

The Internet of Things is gaining popularity and it will enable the development of new applications that will be useful to businesses in almost any industry and in society. It is expected that more than 50 billion IoT devices will communicate via telecoms networks and will send an enormous amount of data. One major challenge to the successful deployment of this large and heterogeneous network is the problem of capacity planning. An in-depth knowledge of IoT traffic characteristics is necessary to optimize the capital expenditure (CAPEX) but no work has been done so far in this area.

All Digital, Multi-Standard Highly Efficient Transmitter forMobile Communication Base Station Applications

A novel transmitter architecture which presents more power efficiency than that of the transmitters being used currently in mobile communication base stations is proposed in this research project. The result of this research fills the gap between the theoretical idea behind this transmitter structure and its practical usage in cellular network base stations. This transmitter can operate over a wide frequency range and with different mobile communication signal standards very power efficiently while maintaining the quality of the transmitted signal.

Exploration of the cloud programming paradigm applied to IMS

For economical and simplification purpose Operators in the Telecom market are looking to move as much as possible of their infrastructure from traditional deployment to Cloud deployment. However Cloud deployment of IMS still need to be defined and developed. This project aims at bringing further the knowledge for such a deployment and helping guide future development for Ericsson. This project focuses on providing future directions for the development of an IP Multimedia System (IMS) in a Cloud environment.

Disaster Recovery as a Green Cloud Service: Balancing Risk, Cost, and Carbon

Unlike centralized computing, which is typically performed in a single data-center, Cloud computing enables the computation to be spread across multiple geographically distributed data-centers which are abstracted as a single system by the Cloud management layer. This computational model enables disaster recovery (DR) by re-establishing the services provided by a data-center affected by the disaster in another healthy data-center capable of hosting the applications providing these services.

"Performance Optimization in 3GPP<->WiFi Traffic Steering *Renewal, previous title ""Stochastic Control in Network Coding Enabled Wireless Systems Year One"""

The mobile traffic has been increased significantly both in volume and in the variety of services in the new generation of broadband mobile networks. This made mobile operators to think about new approaches of data forwarding in wireless cellular networks. With this motivation, mobile operators have started to deploy WiFi to enhance the cellular network capacity. This is done by providing a seamless traffic steering between WiFi and cellular network.

Scalability management for virtualized IMS

IP multimedia subsystem has been identified by mobile network operators as a promising framework for deploying VoLTE and rich communications services. Offering these services in efficient manner makes it even more attractive. Virtualization represents the suitable concept to achieve this. Moreover, deploying IMS in virtualized environment becomes a solution of great potential especially for multi-tenant application providers. This project aims at defining and validating elasticity management approaches of virtualized IMS based on SLA.

Content centric networks

The advent of smartphones and the associated change in usage patterns indicates that carrier voice revenues are constantly going down and are expected to almost vanish in the near future. Data revenues are picking up but not at a rate which will make up for the shortfall in voice revenues. Also, the increase in data revenue is accompanied by a corresponding increase in traffic. This leads to higher costs in deploying and operating networks as well as a significant growth in network complexity. In this project we will be working on

Lossless Ethernet

Telecom operators are demanding more flexible, scalable and energy efficient products. As a system integrator managing networks for operators, Ericsson realize that the benefits of using modern and improved systems is becoming even more critical, as they offer a reduced Operational and Capital Expenditure (i.e. OPEX and CAPEX) of Information and Communication Technology (ICT) systems. The goal of this project is to develop a mechanism to prevent congestion in the network, prevent packets from being dropped and to guarantee delivery of packets between collaborating end-hosts.

IMS applications deployed in virtualization and cloud environments (OpenStack and KVM)

The IP Multimedia Subsystem (IMS) is a key component in the Mobile Next Generation Network, which is used by telecommunications operators throughout the world to provide access to multimedia and broadband services. As these services become more sophisticated, and as the number of clients rises drastically, it is increasingly expensive to install and operate a network that will satisfy the users' expectations. Cloud computing (combined with high-speed networks) provides a potential method for reducing the installation and operational costs of IMS.
