  2. 2. Enabling Roaming Across LTE Networks 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, known as LTE networks. This development will pave the way to full IP convergence, enabling mobile operators to accelerate the time-tomarket for new services that drive customer satisfaction and generate new revenues.
  3. 3. Enabling Roaming Across LTE Networks LTE Networks - Prepare for Roaming As operators launch LTE services in their home markets, consumers will naturally expect the same quality experience everywhere – especially when they are abroad. LTE will enable new services such as video streaming, HD voice and Voice over LTE applications. However, these services will also put high demands on the data roaming backbone and require much more bandwidth and resilient network connectivity.

  5. 5. Enabling Roaming Across LTE Networks As mobile operators review their LTE Roaming connectivity options, they will need to consider the following things to enable LTE Roaming: Diameter Signalling LTE requires a completely new signalling protocol called Diameter. New Roaming Connectivity This new protocol will require mobile operators to establish new roaming connections. Diameter Relay Agent To enable this connectivity, operators will require a Diameter Relay Agent (DRA). An IPX Provider As LTE Roaming proliferates, there will be a need for IPX providers to enable peering both at the data level and at the signalling level.
  6. 6. Enabling Roaming Across LTE Networks An important choice for mobile operators In the new LTE world, mobile operators can work with LTE Roaming hubs, or they can directly connect with mobile operators. Depending on the operator requirements, hubbing allows them to reach operators with one-to-many connectivity, reduce efforts and testing time, accelerate time-tomarket for services and facilitate transaction settlements between operators.
  7. 7. Enabling Roaming Across LTE Networks In the initial stages of LTE Roaming deployments, it is likely operators will use their connection to an LTE Roaming hub to facilitate LTE Roaming. The benefits include: Immediate time-to-market This equips operators to deliver an immediate service to their high-value customers. Cost effectiveness. Mobile operators can monetise their initial rollouts through an LTE Roaming Hub. Technical readiness. An LTE Roaming hub will enable operators to move forward with an LTE roaming solution.
  8. 8. Enabling Roaming Across LTE Networks As the market matures, LTE revenues proliferate, and the necessary network equipment is deployed, mobile operators will also have the option to connect directly with each other. The IPX network will also deliver the bandwidth and network resiliency demanded by consumers.
