Mobile VoIP

Mobile Voice over IP, or Voice over WiFi, empowers operators to offer MSC-based voice services on new IP devices and offer differentiated products that extend mobile services beyond the traditional mobile.

Mobile operators can offer their subscribers new VoIP-based digital phone services without having to implement an IP Core, drastically improving the business case by utilizing the existing mobile core network (MSC) to deliver mobile Voice over IP (VoIP). Operators do not need to invest in deploying a parallel VoIP core, thus saving both CAPEX and OPEX.

Unique Business Value:

Service Differentiation / Network Transformation - Multi Device (or Access) Voice

Users can choose the devices while connecting using the existing mobile core network. Operators can offer primary or secondary line voice service over any 4G or residential broadband connection – Voice over WiFi, Voice over LTE (VoLTE), Voice over WiMAX, and Mobile Voice over fixed devices. The types of devices can be any of the following:

  • Smartphones with Voice over WiFi
  • Tablets
  • PC Softphone and Web clients

Service Differentiation - One Number

One number makes users reachable across multiple devices, since a unique number identity is tied to the user, not the device. For incoming calls to a single number, all provisioned broadband devices within the group may be alerted, providing the freedom of choice between devices. One number service across mobile and broadband devices can also be enabled with MSC/IN or IP based Service Node concepts.

Service Differentiation - Mobility

Unique mobility options to provide service differentiation such as Push to Move/Push to Grab across various broadband devices.

 


Solution components:

Enabling VoIP (Voice over WiFi) service from the Mobile core network is accomplished as a relatively simple overlay to the existing core network.

  • MSC TAS to deliver MSC services to IMS devices. The solution can best be described as a SIP BSC (Base Station Controller) that provides IP-based network connectivity for SIP-enabled devices, and connects to the existing MSC via open standard A Interface. To further add to the simplicity of the solution, the mobile operator uses the existing provisioning and billing systems for VoIP service.
  • MSC TAS in the IMS model, the SIP BSC connects to any standard compliant IMS core S-CSCF as an application server. In this model the MSC in combination with the Mavenir SIP BSC acts as a Telephony Application Server (TAS).
  • Mobile TAS for next generation of all-IP, IMS based rich voice and video telephony services, based on 3GPP MMTEL standards.
  • Mobility Server to enable mobility and service continuity across WiFi (Mobile VoIP), 4G (VoLTE) and 2G/3G (Circuit) domains.

Mavenir works with industry players to complement our solution with various components required to deliver a turnkey solution. The Mavenir components are complemented by industry leading partner components including the Session Border Controller (SBC), Media Gateways (MGW) and Professional Services to provide a turnkey offer. The Mavenir application servers also work with any 3GPP Release 8 compliant IMS vendor equipment that may already exist in the network. Read more about our Partners.
