Ericsson pushes HSPA world record to 56Mbps. – Ericsson will break its own HSPA world record with the world's first demonstration of HSPA multi-carrier MIMO technology, providing peak downlink data rates of 56Mbps, at the CTIA Wireless exhibition, April 1-3 in Las Vegas, USA. – The increase in speed is achieved thanks to a combination of multiple-input-multiple-output (MIMO) and multi-carrier HSPA technology. MIMO allows for higher peak data rates and increased spectral efficiency, which provides higher network capacity. – HSPA multi-carrier technology with MIMO, which is currently being standardized, is scheduled for commercial deployment in 2010. By the end of 2009, Ericsson will support commercial deployment of multi-carrier technology with speeds up to 42Mbps - an achievement successfully demonstrated at the recent Mobile World Conference in VICTOR MANUEL QUINTERO FLOREZ Barcelona.

    Voice over LTE: Status and Migration Trends Page 1 of 15 Voice over LTE: Status and Migration Trends Lav Gupta, lavgupta (at) wustl.edu (A paper written under the guidance of Prof. Raj Jain) Download Abstract Rapid increase in data traffic over cellular network is necessitating deployment of Long Term Evolution (LTE) in the cellular operators networks. While LTE provides efficient data traffic handling and high data rates, it lacks native circuit switched voice capability. The GSM association has standardized IP Multimedia Subsystem (IMS) based VoLTE solution along with Single radio SRVCC for handover. Migration to this solution requires operators to have expensive and complex IMS deployments. This has led to operators leveraging the existing 2G/3G networks with VoLTE methods like Circuit Switched Fallback (CSFB) and Voice over LTE via Generic Access (VoLGA). This paper describes both, the interim and the long-term, solutions for the operators and their respective pro and cons. Future directions in VoLTE research have also been briefly described.

  • Performance Evaluation of VOICE CALL HANDOVER BETWEEN
    PERFORMANCE EVALUATION OF VOICE HANDOVER BETWEEN LTE AND UMTS Joyce Namakoye A Research Report submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science in Engineering Johannesburg, 2011 DECLARATION I declare that this research report is my own unaided work. It is being submitted for the Degree of Master of Science to the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or examination to any other University. Candidate Signature : Name : Joyce Namakoye Date : 10th January 2012 i ABSTRACT The main objective of seamless mobility is to enable mobile users to stay connected while roaming across heterogeneous networks. As cellular networks evolve from the third generation Universal Mobile Telecommunication System (UMTS) to the Long Term Evolution (LTE), a new Evolved Packet Core (EPC) will support heterogeneous radio access networks on the same platform. UMTS provides voice services in the circuit switched domain; while LTE operates in the packet switched domain. Cellular network operators thus face the challenge of providing voice services during initial deployment of LTE due to difficulty in mobility between the two domains. Seamless voice handover between packet switched LTE and the circuit switched UMTS network is therefore an important tool in solving this problem. This report investigates the performance of inter-Radio Access Technology voice handover between LTE and UMTS. The schemes evaluated were Voice Call Continuity (VCC) for UMTS to LTE handover and Single Radio Voice Call Continuity (SRVCC) for LTE to UMTS handover.
