When two large companies merge, it often takes a while – years in some cases – before processes get redesigned to span all departments, and the new organization settles into a lean and profitable machine. And the same is true of OSS/BSS. These systems have been designed for two different purposes: to keep the network operational and to keep it profitable. But today’s demanding networks need the functions of both of these systems to work together, and to work across the varying lifecycles of products and services.
There are many factors that have contributed to the extensive use of fiber in telecom networks. As a result of the bandwidth and speed it can offer per dollar spent, the use of fiber is becoming more extensive being pushed deeper and deeper – particularly in the last mile. In a field trial carried out by Ericsson and Telstra, technologies to meet operator demand for seamless upgrade of networks were put to the test.
The concept of self-organizing backhaul networks is not yet as widespread as the concept of SON in the context of radio-access networks. There are, however, ways in which backhaul networks can benefit from SON technology and delay investment in new architecture.
As HSPA evolution continues to address the needs of changing user behavior, new techniques develop and become standardized. This article covers some of the more interesting techniques and concepts under study that will provide network operators with the flexibility, capacity and coverage needed to carry voice and data into the future, ensuring HSPA evolution and good user experience.
Just a couple of years ago, the concept of allowing third-party access to operator assets was practically unheard of in the telecom industry. Today, the picture is quite different. Service exposure is about to create a whole new set of business possibilities for operators, developers and content providers.
There is more to a good user experience than attractive products and services that solve problems and function according to a given set of requirements. Creating products and services that provide compelling experiences for users requires planning, resources, and processes for monitoring progress and measuring quality – crafting UX.
Requiring only half the bitrate of its predecessor, the new standard – HEVC or H.265 – will significantly reduce the need for bandwidth and expensive, limited spectrum. HEVC (H.265) will enable the launch of new video services and in particular ultra HD television (UHDTV).
Delivering a broader portfolio is a challenge. Providing subscribers with the products they pay for in real time – good QoE – and has put the separation of online charging systems (OCSs), the policy and charging rules function (PCRF) and fulfillment systems to the test. To bridge the gap between content and communication services and close the gap created by the shift to real-time charging greater synchronization between OCS and PCRF is needed.
The evolution to denser radio-access networks with small cells in cluttered urban environments has introduced new challenges for microwave backhaul. A direct line of sight does not always exist between nodes, and this creates a need for near- and non-line-of-sight (NLOS) microwave backhaul.
