VoLTE also named as Voice over long term Evolution is a standard for high-speed wireless communication for mobile devices and data terminals. Voice has traditionally been working on circuit switched CS network. To get over this issue, VoLTE was defined. From an LTE network point of view, voice and its associated signaling are just data like any other data with a higher priority though.
Since LTE is data only network, the networks realized that they can use WiFi for the access network in the same way. Voice over Wi-Fi is counter to Voice over LTE in which licensed spectrum mobile network operators are used to carrying packetized voice.
In old days when you were on a call with a friend and you decided to play some movie along and want to check the listings while remaining on the call. T-Mobile customers were able to this form a long time.
However e. Sprint and Verizon subscribers had to end call first to switch to the other task. One cannot measure the high quality of these calls but they have improved a lot when compared to traditional calls which were made via cellular networks. As HD calling uses data network, there is misconception that the voice minutes will affect the data allotment.
It should be kept in mind that all the devices do not support VoLTE but many does. The new flagship devices of Mobile giants like Samsung, iPhone and Huawei do support it. It will take time and slowly but gradually, all areas will be facilitated with this technology. All that switching, plus the need to search for a different signal each time, can give the battery a significant hit.
With VoWiFi superior call quality, users can have better conversations. For businesses, better call quality will save time for employees and boost their efficiency.
Sometimes due to weak cellular reception in homes, office etc. Poor indoor coverage is the worst nightmare but with the inception of VoWiFi, the problem is solved.
VoWiFi facilitates users to make and receive calls reliably even when indoors without having to install new equipment or upgrade their smartphone. However with VoWiFi, one can easily save a lot of money while talking to the dear ones. VoWiFi enables free calls from overseas and roaming locations. VoWiFi enables non-subscriber devices like Wi-Fi tablets to make calls and enables free calls overseas. And when customers have good service experience, they are more likely to stay with their current service provider and tell others about it, which in turn helps service providers reduce churn and attract new customers.

LTE roaming: Issues, challenges, opportunities
Featured Content. Follow Mobile World Live. Get Our Newsletter.Tags: Roaming. Initially, most operators designed their LTE network to support non-voice data services, with voice calls remaining on their 3G network. This was done to launch LTE more quickly and with minimal cost. But that trend is changing.
According to a leading industry report, VoLTE subscriptions are expected to reach 5. Close to 50 operators worldwide have announced the closure of their 3G Networks, and many more are expected to follow in the coming months and years, transforming them to pure LTE network making VoLTE mandatory for voice. We live in a world where people travel the globe and still expect to be connected - wherever they go. But what does this mean for MNOs and their roaming partners? Globally, there are fewer than thirty commercial VoLTE roaming agreements in effect today.
The GSMA has already resolved the key technical challenges related to lawful intercept and emergency calling. This is giving operators greater confidence to establish support for VoLTE roaming.
There are models available now to address uncertainty on the positive or negative impacts of implementing VoLTE roaming. GSMA also provides assistance for these models. VoLTE is one of the key priority for many operators as this will enable them to offer better user experience to their subscribers for voice calls. This attitude has shifted. Many mobile operators are already shutting down their 3G networks, and many more are planning to do the same in the near future.
Overcome the complexity of VoLTE Roaming:
There is now a growing sense of urgency to establish VoLTE roaming capabilities - or risk subscribers losing access to voice services while traveling. MNOs need to gear up their steering platforms to ensure that only VoLTE subscribers with the right handsets are steered to pure LTE networks, while others subscriber are kept on 3G networks. This is required to ensure roamers receive uninterrupted voice services, while also ensuring wholesale costs are optimized.
Typically, TAS is not overloaded with multiple roaming related use cases, like shortcode translations and call corrections, which are VPMN-specific. Also, MNOs need to ensure that their TAS node, and other complementary solutions, are geared up for other roaming related use cases like fraudulent call blocking, fair usage policies, bill shock notifications, and fraud prevention.
These policies are typically dependent on the visited location. Like any other roaming agreement, setting up VoLTE roaming agreements can be expensive both in terms of cost and manpowerand time consuming. From a performance and resource perspective, MNOs should also look at automating VoLTE roaming testing as much as possible, rather than doing it manually.
With 5G Standalone Modethere is no support or fallback to circuit switched voice calls. The IMS core is a mandatory requirement. Moving to IMS for voice services today will provide operators with an easier path to 5G tomorrow. For more information on VoLTE roaming and how we can help, contact us today. In six short months, the Coronavirus pandemic touched almost every corner of the world. However, visibility into ho Our research shows there have been four key reasons for this low adoption rate: 1.
Technical challenges: VoLTE calls, from a technology perspective, are very different than traditional 3G calls, which impacts current rules and regulations around Lawful Interception LI and Emergency Calling services. Financial implications: Under VoLTE, voice services are billed not as minutes of use - but bytes of data consumed.Customers will benefit from near-instant call setup, better sound quality and the ability to have HD Voice conversations with more users outside the mobile-only community.
VoLTE is viewed as a critical next step in continuing to deliver a high quality voice experience. It offers customers HD Voice, while enabling mobile network operators to operate on the basis of an all-IP infrastructure. This is significant in that it produces operational efficiencies and the required foundation for deploying new services, as well as integration for further applications aimed at improving user experience. For mobile network operators, the improved quality leads to increased usage, and ultimately, better revenues.
Mobile voice quality issues are an ongoing concern for network operators and investing in VoLTE is set to greatly reduce customer churn and improve the customer experience. Adding VoLTE to the portfolio also provides mobile operators with a potential competitive advantage over OTT providers, who may not be able to match the quality of experience.

When VoLTE subscribers roam internationally or even within their own countries, their voice calls will most likely use a local 3G network — a.
This is not ideal for operators or their customers. For starters, due to different interpretations of IMS standards, VoLTE networks are not easily interoperable, which makes interconnection, peering and roaming difficult.
In addition, there are several reference architectures for implementing VoLTE roaming, and each has distinct advantages and disadvantages:. It ensures interoperability regardless of the roaming architecture utilized.

In addition, there are several reference architectures for implementing VoLTE roaming, and each has distinct advantages and disadvantages: Local Breakout LBO — Calls are broken out locally. LBO Visitor Routing LBO-VRwhich is characterized by an interaction between the visited network and the home network to establish features and capabilities, with the call finally being routed by the visited network using its carrier relationships.
Because it is an easier solution than LBO, it has been used in some early VoLTE roaming deployments, but it is also considered an interim measure. In an ideal world, a VoLTE roaming implementation would meet four key requirements: The visited country requirements are met, such as emergency calling, regulatory and local numbering plans. The home network is in control.
That is, the home network decides how best to route calls and controls user services. Media is routed via shortest path.
5 things you should know About VoLTE and VoWiFi
The media is optimized so that it takes the shortest path between handset and destination network. Implementation should be simple, quick and easy to adopt and test with each new roaming partner. Steve Gleave.
