Voice over LTE - Ebook

Our portfolio includes industrialized solutions to launch VoLTE services in weeks instead of months, as well as automated acceptance tests to reduce the TTM of new services you develop. This guarantees full device interoperability and allows for direct IP interconnect and roaming towards other operators. A core network solution that delivers real-time communication services for consumer and business users. Built on world-class test applications, Ericsson Automated Acceptance Tests performs large amounts of automated The solutions are also fully optimized for cloud deployment, agnostic to the underlying infrastructure for both media and control plane, and include critical automation to simplify creation and maintenance of end user services. Using feedback from device partners, the solutions are architected and designed to serve today's market where subscriptions are no longer simply one user with one device and one phone number.

Voice over LTE

When early specification work on LTE started, it was assumed that by the time it was ready for deployment, IP Multimedia Subsystem IMS would be sufficiently advanced that a packet voice solution would already exist and would be relatively simple to "drop on top" of LTE. This has resulted in the development of an "IMS gap. About Us. Contact Us. Follow Us:. Login to your account.

Next generation networks utilize an exhaustive list of architectural components that need to work seamlessly to enable end-to-end services for customers that demand connectivity and content at any-time, any-place and on any device. The following is a list of select interfaces, network nodes and acronyms to better navigate the technical aspects of modern service delivery networks. Optional Media Resource Broker MRB support for seamless scalability without application re-writes and network reconfiguration. Find Out More. Dialogic Service Provider Solutions. Nodes Acronyms. TS

The flow starts every time it is collected, that is why we see "Flow started" when we call collect again. When you do this, the call ends for all participants at the same time. Nemo RF Network solutions support all the latest Nemo technologies e. If your network is live, ensure that you understand the potential impact of any command. The certificate is valid for a term of two 2. The call initiated by UE is known as mobile originated call or mobile originating call. For a flexible update flow, triggers the completion of the update.

IMS VoLTE and 3GPP Nodes

UE is a mobile terminal authorized to be used in an LTE network. UE may be a smartphone, tablet or other communication devices. ISIM contains the following:. SIP-UA provides basic telephony functionality. It can act in two different roles:.

Just as wireline carriers have been abandoning traditional circuit-switched voice for VoIP over the past decade, now mobile carriers are looking to do the same. Adopting this approach, it enables the system to be integrated with the suite of applications that will become available on LTE. When 3GPP started designing the LTE system, prime focus was to create a system which can achieve high data throughput with low latency and at the same time has the. However, service providers also need to have a clear strategy of how to offer voice.

Further VoLTE performance aspects such as parameter optimization and HD voice are discussed, thus serving as a basis to then analyze the DACH mobile network test results for in terms of telephony and data performance. The increasing gap among capacity and demand poses an urgent call for novel network technologies to allow mobile operators to improve performance on a cost-effective basis. In fact, Voice over Long Term Evolution VoLTE is a key component for an innovative set of services determined for all-IP networks: the goal relies on making these novel applications as available as voice and messaging are nowadays, while also offering a flexible interaction with Internet applications. Indeed, LTE focus on a rather flat all-IP access technology aiming at delivering a bandwidth-efficient approach for carrying several types of subscriber traffic at the same time. In other words, the capability of transporting Voice over IP VoIP services along with the provision of high-rate data throughputs, characterizes one of the critical drivers for the development to LTE. As of December , six countries have deployed VoLTE 1 services and still 56 others are currently preparing its implementation [30]. For many operators, VoLTE embodies a future-proof approach to rich media services, thus leaving no other reasonable alternative than to opt for its swift implementation.

Voice over LTE

Historically, mobile phones have provided voice call services over a circuit-switched -style network, rather than strictly over an IP packet-switched network.

We will make the entire picture clear and backup all that we teach with call flows and live labs using an IMS platform. This course also covers enough of other technologies like Diameter and DNS to allow you to understand the complete picture. The lessons in this course are clear, very technical, and always practical, and since much of it is hands-on, you can investigate and reinforce each lesson.
