Voice over LTE (VoLTE)

Voice over LTE empowers 4G LTE operators to offer rich voice, video and messaging services as a core offering. Transformation of circuit-switched networks that carry voice to all-IP 4G LTE networks will realize cost advantages and recover inefficient spectrum for additional data capacity. With 4G, LTE and WiMAX operators can leverage service ubiquity, access mobility, global interoperability and universal user identity of phone number to enable continued monetization of voice and messaging. These fundamental values will help mobile operators compete against the OTT web-based service providers and establish an environment where new user experiences can be offered to any generation of mobile devices.
Mavenir provides 4G Services solutions that power the next generation of voice, video and messaging services over LTE and WiMAX devices, based on widely accepted 3GPP/2 IMS and OMA standards which provide a framework for global interoperability across networks and the traditional circuit domain networks. Mavenir has introduced key innovations to help operators with service differentiation including IMS Centralized Services - 3GPP ICS, that extend the SIP and IMS-based services to 2G and 3G devices empowering true convergence with the single core network.

Mavenir's solution gives mobile operators a time-to-market advantage using a single Mavenir mOne™ Convergence Platform that supports a wide variety services including VoWiFi, VoLTE, SMS/MMS over 4G, and RCS.

Unique Business Value:

Mavenir's 4G LTE Converged Services solution offers a compelling business case with rapid deployment of rich voice, video telephony and RCS services including presence, messaging and media sharing services across 3G and 4G/LTE devices. Mobile operators increase customer loyalty and revenues with new user experiences. Mavenir powered services help solidify mobile user communities around real time communication services to empower operators grab services market share vs. commoditizing into a pipe provider.
Service Differentiation – Service Parity with Legacy Voice
Subscribers will expect complete service parity with a voice enabled 4G device. This includes delivery of CAMEL and WIN based services such as Prepaid, Ring Back Tones, Short Code and Mobile Enterprise VPN. Mavenir offers a range of options for voice services such as reuse of MSC using the MSC TAS product or the use of Convergence TAS with 3GPP/2 call models including CAMEL and WIN triggers to integrate with legacy SCP service platforms. Only Mavenir offers these critical starting points for mobile operators.
Service Differentiation – Converged Voice
Mavenir 4G Converged Services solution enables enhanced services such as One Number (like Google Voice), Multi-device call handling, group conferencing for both Voice and Video to compete against the web services like Google Voice and Skype.  Mobile operators can further differentiate from the web providers with access domain mobility and QoS management to provide a better and simpler service experience to the end users.
Service Differentiation – Converged Messaging
Messaging is a vital source of revenue for global mobile operators, making it critical to continue to offer SMS and MMS over 4G and launch new capabilities to keep the service attractive for an end user. The RCS solution introduces rich messaging services from simple text IM to conversational and group messaging. Bundled with Media sharing, industry driven interoperability, operators can truly grab the opportunity to offer simple but rich user experiences over their multi-generation access networks. The service is extended to non-RCS mobiles via SMS, MMS and Web, with network intelligence to route the message to available device or the client. Read more about Mavenir Converged Messaging solutions.
Service Differentiation – Video Telephony
New smart phones and IP connected devices such as game consoles, tablets, book readers are enabled with video cameras for video recording and content playback from sites such as You Tube. With the Mavenir solution it is easy for mobile operators to offer differentiated value of video telephony services. Video enhances the VoIP value proposition also which leverages hotspot WiFi and up coming 4G coverage. Unlike web service providers, Mavenir controls the seamless transfer of video to voice or vice versa based on access domain availability.
Service Differentiation – Integrated Solution with a Single, Scalable Platform
The entire 4G Converged Services solution is based on our flagship, highly scalable mOne convergence platform with carrier grade reliability and industry leading capacity. The collapsed architecture drastically reduces entry costs for SIP / IMS services and enables operators to focus their resources on marketing and creating differentiated features instead of dealing with operational complexities. The integrated approach makes it easy for mobile operators to focus on services innovation in a highly competitive market. It offers multiple deployment options with distributed or integrated functionality. The modular software architecture with flexible service logic execution engine enables continuous innovation to offer rich end user experience.
