Solving the 4G Roaming Puzzle

As the growth of 4G LTE networks gathers pace many operators are hitting unforeseen challenges as they look to interconnect with legacy networks and ensure their subscribers aren’t left hanging when they step out of their home network.

We look at the challenges for operators and the solutions to roaming and interconnect between LTE and legacy networks.

What's Next for IMS - and how will SDN, network slicing and 5G impact?

Since its inception in 1999 the IP Multimedia Subsystem (IMS) has been the underlying network architecture for 4G rollout worldwide. Successfully standardising the delivery of IP telco networks by splitting the control layer from the network and application layer we look at what the drivers will be for IMS networks in the next 5 years, and what impact SDN, network slicing and 5G will have.

Squeezing more from IMS, NGN & Legacy Networks

The rise of the OTT’s and the increasing abundance of IP networks means operators are in a constant battle to retain and seek new revenue. Keeping existing subscribers happy whilst looking to take advantage of evolving technologies in the IMS, VoWiFi, 4G, 5G and IoT space is a fine balancing act.

Deploying a VoLTE Network

Deploying VoLTE networks is complicated - So much so that Vice President of China Mobile Group, Mr Liu Aili is quoted as saying… “VoLTE network deployment is one of the most difficult projects ever, the implementation complexity and workload is unparalleled in history”.

We look at what drove this reaction and talk more about our experiences of deploying a VoLTE network.

Revenue and Growth Still In SMS

As late as 2014 it was predicted there would be a continued decline in SMS traffic worldwide with the exception of emerging markets. The ascendancy of OTT apps is in no doubt, and for P2P (Person 2 Person) communication its dominance will continue to grow for a wide range of reasons.

BUT, what has happened and can be seen clearly in hindsight is the growth in A2P communication…
