VoLTE Roaming and 4G Roaming for Mobile Data

Enabling Seamless VoLTE & 4G Roaming

Mobile customers have high expectations for easy, unfettered access to services wherever they are, so it’s important for Service Providers to enable seamless roaming across diverse network technologies for both Voice over LTE (VoLTE) and 4G/LTE networks.

The reality is that a large percentage of subscribers block their mobile data access, rely on OTT applications or even turn off their device when roaming outside their carrier's operating area to avoid bill shock. That behavior translates into a huge loss of potential revenue for operators.

Dialogic solutions can enable Mobile Network Operators, IPX operators, MVNOs and Wi-Fi operators with solutions to help interwork services and networks to better monetize their investment in new technology as well as their existing infrastructure.

Dialogic VoLTE Roaming and 4G Roaming Enabling Solutions

VoLTE offers faster connections and improved voice quality compared to OTT and circuit switched connections. Service Providers can roll out HD Voice and video sharing services with an end-to-end VoLTE solution built on the unmatched flexibility of our IMS-surround components that include:

  • Virtualized Diameter Signaling Control (DSC);
  • An open and highly scalable Media Gateway Control Function (MGCF);
  • Modern IMS media gateways;
  • Virtualized IMS-ready Session Border Controllers (SBCs);
  • NFV-ready Media Resource Function (MRF) for scalable video and voice media mixing, recording/playback, tones and announcements, IVR;
  • Audio and video transcoding, transrating and transizing;
  • Intelligent Media Resource Broker (MRB) function for stateful and transparent brokering of traffic for IMS application servers

Enabling VoLTE roaming is the next logical step in differentiating networks and giving inbound roamers a better user experience. Along with our advanced signaling control and security functions, operators can support either home routed, local break out or even regional break out of services depending on what’s optimal for the call.

IPX: A Trusted Intermediary for Roaming Enablement

IPX Operators can expand their existing array of services with mobile data and voice roaming solutions. Dialogic’s IPX platform enables operators with a flexible solution to support VoIPX and TDM termination and interworking, and can offer value added 4G, 3G, VoLTE and Wi-Fi roaming enablement services:

  • LTE, 3G. Wi-Fi Roaming Hub

4G Roaming Opportunities

MNOs can take advantage of Dialogic’s signaling interworking solutions to help leverage their 4G investment by enabling secure inbound roaming of both 4G and 3G subscribers.

Local break out of mobile data for 4G roaming is complex and can involve the sharing of policy, charging and authentication information between your network and your customer’s home network. A next generation Diameter Signaling Controller makes implementing 4G roaming for mobile data users easier with an intuitive, GUI-based approach to managing, mediating, enhancing and interworking signaling unlike any other solution on the market today.
