IMS Roaming and Interoperability for VoLTE and RCS

With more than 200 LTE network deployments since 2010, the issue of isolated mobile networks is becoming more prevalent.

According to the GSMA, RCS (Rich Communication Services) adoption is also picking up pace with deployments in 11 countries, supported by 17 operators. This figure is expected to grow to 85 operators by next year.

Combining the Voice-over-IP capabilities of VoLTE (Voice over Long-Term Evolution) with RCS enables operators to offer innovative multime­dia services with strong security and quality of service.


Combining both data and voice services on the same LTE data access network enables mobile operators to optimise network and service management, integrate network resources and simplify service delivery; this results in a significant reduction of operating expense.

This will make their operations easier and less expensive to manage. Operators will be able to pack more information into packets that go from consumer phones to operator cell towers—which is what enables consumers to send more data stream videos. This is vital at a time when the demand for data between consumers on mobile devices is accelerating at a phenomenal level.

The move to super-efficient networks means operators are able to offer new types of services such as video calling and high-definition content streaming. The benefit of offering VoLTE not only increases the possibility for mobile operators to offer better quality voice services, but also enables them to expand to other services such as rich communications. It also changes how they price and sell services to consumers.


Additionally, the evolution of RCS is about interconnecting operators over IPX to expand the consumer base. Regardless of network type, operators need to interoperate globally to offer quality services regardless of subscriber location.

Mobile operators will take advantage of the IPX and its IMS (IP Multimedia Subsystem) interconnect hubs to establish a global nextgen service.


Over the past few years, just over half (56%) of operators have moved to connect with IPX networks in order to meet heavy demand for 4G/LTE connectivity around the world. This uptake means faster, higher quality roaming capabilities for consumers and greater access to networks’ LTE spectrum offerings.

We’re committed to expanding the LTE roaming and interconnect community, and supporting mobile operators in providing a seamless global roaming experience for mobile subscribers.  Just last year we were the first to announce a standards-compliant IMS roaming and interconnect hub for IP-based services, including VoLTE and RCS. This will help to establish a global community in which subscribers can communicate beyond traditional voice and messaging services across any device, network and geography.

Tackling LTE Roaming Challenges

Once again the mobile industry is entering a new phase of technological change. With the proliferation of data services and smartphones, the mobile operator community is working to address the increasing need for bandwidth with the rollout of next generation 4G networks.

As operators launch LTE services in their home markets, consumers will naturally expect the same quality experience everywhere— especially when they are abroad. In view of this, mobile operators that deploy LTE networks in their domestic markets are starting to review available options to ensure LTE services allow seamless roaming overseas.

The first users of LTE will typically be VIP customers or key corporate accounts, a segment made up of high-end users and frequent travellers. To serve these premium customers operators will need to address LTE roaming requirements sooner, rather than later.

Prepare for roaming

LTE enables new services such as video streaming, HD voice and Voice over LTE applications. However, these services also put high demands on the data roaming backbone and require much more bandwidth and resilient network connectivity.  As mobile operators review their LTE Roaming connectivity options, they will need to consider the following business and technical factors in preparation to enable LTE Roaming:


Local Breakout – A new challenge for networks

Going on holiday this summer? In this post, Michel van Veen, IPX business manager for SAP Mobile Services takes a look at the how Local Breakout and IPX will enable operators to meet the strategic challenges presented when customers roam.

As LTE rollouts gain pace, consumers will have access to new networks and higher data speed. While it will take time for the end-user market to catch-up with the industry’s perceptions, the industry still needs to address certain expectations around LTE.


At first glance the roaming advantages dominate the LTE experience. Local Breakout, a mechanism where roaming traffic does not traverse back to the home network and is handled by the local operator, allows for cheaper tariffs and will also bring increased localised revenue. The challenge for the network operators is to understand how and where the placement of Local Breakout can be advantageous for them.
