Overview of GSMA PRD IR.92 5. Service Continuity 6.Systems Voice over LTE Verification sdfsdf7. Summary 8. References Motivations for Enabling Voice over LTE The motivation for the deployment of 3GPP Long-term Evolution (LTE) mobile broadband technology is simple: All things considered, LTE delivers to carriers the lowest cost-per-transported bit. That said, the adage that “voice pays the bills” still applies: though in decline, carriers continue to derive the bulk of their revenues from voice and integrated messaging services. In the context of LTE, this presents a dilemma. A fundamental aspect of legacy technologies such as GSM, UMTS, and cdma2000 is that they possess integrated services1: voice, voice supplementary services (e.g., call forwarding), short messaging, etc. In contrast, LTE makes no such provisions: it is subscriber service-agnostic. Further, LTE is a pure packet technology, with no inherent conception of a circuit-switched (CS) bearer, on which legacy voice services depend. Because of the realities of the cellular revenue model – and, indeed, because cellular subscribers expect service continuity – the question arises: How can we best deliver voice and other legacy services via LTE? As with any engineering exercise, this requires articulation of the requirements. Requirements for Voice over LTE The requirements for voice2 over LTE (VoLTE) solutions fall into one – or both – of two categories: the requirements of cellular subscribers, and the requirements of cellular carriers.

  • Voice Over LTE: Status and Migration Trends Page 1 of 15
    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. Keywords VoLTE, Circuit Switched Fall Back, CSFB, Voice over LTE via Generic Access, VoLGA, Single Radio Voice Call Continuity, SRVCC, IMS, IP Multimedia Subsystem, handover, Evolved Packet Core, Evolved UMTS Radio Access Network, MME Table of Contents 1 Introduction to LTE and VoLTE • 1.1 LTE Overview • 1.2 Basics of Voice over LTE 2 VoLTE Architectures and Protocols • 2.1 Circuit Switched Fallback (CSFB) • 2.2 Voice over LTE via Generic Access (VoLGA) • 2.3 GSMA profile for VoLTE • 2.4 OTT Solutions

    White Paper Single Radio Voice Call Continuity (SRVCC) with LTE By: Shwetha Vittal, Lead Engineer Overview CONTENTS Long Term Evolution (LTE) is heralded as the next big thing for mobile Why SRVCC? pg. 2 networks. It brings in promising technologies such as semi-persistent Single Radio Voice Call Continuity scheduling, transmission time interval (TTI) bundling, and high performance From LTE pg. 3 gains on Quality of end user Experience (QoE). In the end, the primary goal of LTE is to deliver ultra-high speed mobile broadband with peak data rates over SRVCC from LTE to 3GPP2 1XCS pg. 4 100 Mbps. However, in practical applications LTE is facing challenges to provide SRVCC from LTE to 3GPP UTRAN/GERAN pg. 7 the same capabilities as a 2G/3G network during the initial stages of trial deployments and operators’ metered investment in broad network build out. Conclusion pg. 9 One of the key issues of LTE is the delivery of voice services. Voice remains the References pg. 10 “killer application” for operators because it still accounts for a large portion of their revenue. Voice will continue to remain the dominant must-have service in the network for years, and despite the technical challenges of providing service over an all-Internet Protocol (IP) radio access network (RAN), voice is seen as a basic service by the consumer; in short, it is expected. However, voice service continuity is not guaranteed when a Voice over IP (VoIP) subscriber roams between the LTE coverage area and other wireless networks—and it is a significant challenge to deliver voice over LTE networks.
