The benefits of a dual-mode 5G Core Taking a dual-mode approach to core evolution Ericsson’s knowledge and experience now apply to 5G. Commercial deployments will feature one core for multi-access and service delivery, known as a “dual-mode 5G Cloud Core.” This solution enables communications service providers to introduce 5G services flexibly and at their own pace, supporting current services while reducing total cost of ownership (TCO) with an all-cloud native solution. Simultaneously, Ericsson is introducing new network exposure capabilities, which will drive new revenue opportunities by making the core network truly programmable. Network traffic and subscription forecasts continue to grow, boosted
by the anticipation of new 5G-enabled applications and complementary technologies, such as the Internet of Things (IoT) and vehicle-to-everything (V2X). By 2024, mobile data traffic is expected to see a 30 percent compound annual growth rate (CAGR) – 35 percent of which is carried by 5G networks. Next-generation technologies will help create applications that are not yet imaginable, but delivering them reliably and profitably requires an efficient, flexible and programmable core network.
Steps to a smooth 5G introduction From a core perspective, there are two main phases to supporting 5G New Radio (5G NR). The first phase – non-standalone (NSA) – is based on an enhanced Evolved Packet Core (EPC), which Ericsson calls 5G EPC. This phase supports 5G NR radio using an updated 4G core. The second phase – NR standalone (SA) – is a new 5G core (5GC) built on a service-based architecture (SBA). The timings and steps each service provider takes on their 5G journey will
