Key Terms

5g standalone, dual-mode 5g core, ip multimedia subsystem, mobility management entity, +4 more

8 terms

5g standalone technical

"Agreement accelerates the transition to 5G Standalone (SA)."

5G standalone is a mobile network built entirely on native 5G core and radio technology rather than relying on older 4G systems — like constructing a new end-to-end highway designed for modern traffic instead of adding lanes to an old road. It matters to investors because it unlocks lower delays, greater capacity and flexible virtual “lanes” for different business uses, which can drive new services, higher device demand and different capital and revenue dynamics for carriers and equipment makers.

dual-mode 5g core technical

"Ericsson's cloud-native dual-mode 5G Core solution, as well as Ericsson Cloud IMS"

A dual-mode 5G core is the central network system that can run both legacy 4G services and the newer 5G services at the same time, allowing carriers to support old and new devices during a technology transition. For investors, it matters because it reduces the cost and risk of upgrading networks—like a train station that handles both older and faster trains—enabling faster rollouts, broader customer compatibility, and clearer paths to new revenue from higher-speed services.

ip multimedia subsystem technical

"cloud-based IP Multimedia Subsystem (IMS) solutions.These solutions will enable SoftBank"

IP Multimedia Subsystem is a standardized network framework that lets service providers deliver voice, video, messaging and other real‑time services over Internet Protocol (IP) networks, replacing older circuit‑based systems. For investors, it matters because IMS can speed deployment of new services, improve compatibility between networks and reduce operating costs or unlock new revenue streams—think of it as a common app platform for telecom services that enables faster innovation and partnerships.

mobility management entity technical

"Existing subscriber mobility functions, MME (Mobility Management Entity) and AMF"

A mobility management entity is an organization that plans, coordinates and oversees transportation and mobility services for people who need help getting to medical appointments or living independently, including arranging rides, adaptive equipment and related support. For investors, these entities matter because their efficiency, contract terms and compliance with healthcare rules influence patient access, provider costs and predictable revenue streams—like a traffic controller whose skill can reduce delays and operating expense for the whole system.

access and mobility management function technical

"MME (Mobility Management Entity) and AMF (Access and Mobility Management Function) nationwide"

A network control component that handles how devices connect to and move across a mobile operator’s network, including verifying access, routing initial connections, and maintaining service when a user changes location—think of it as the traffic controller and gatekeeper for phones and IoT devices. Investors care because it directly affects network reliability, customer experience, rollout speed for new services, and operational costs; upgrades or problems with this function can influence subscriber retention and revenue.

massive mimo technical

"deploy AI-powered external control system to optimize Massive MIMO coverageSoftBank Corp."

Massive MIMO is a wireless technology that uses large numbers of antennas at a cell site to send and receive many signals at once, boosting capacity and reliability like turning a single-lane road into a multi-lane highway for data. It matters to investors because it can dramatically increase network speed and efficiency, reduce per-user costs, and drive demand for equipment and services from telecom operators and suppliers.

cloud-native technical

"Ericsson's cloud-native dual-mode 5G Core solution running on Ericsson's Cloud Native"

Cloud-native describes a way of creating and running applications that are designed specifically to operate smoothly on cloud computing platforms. Think of it as building a house with flexible, lightweight materials that can be easily moved, scaled, or adjusted as needed, rather than using rigid, traditional construction. For investors, it signifies technology that is more adaptable, efficient, and capable of quickly responding to changing market demands.

orchestration technical

"Orchestration and automation on cloud infrastructure will simplify operational processes"

Orchestration is the coordinated management of multiple tasks, systems or teams so they work together smoothly, like a conductor ensuring each instrument plays at the right time. For investors, orchestration matters because it improves efficiency, speeds up delivery, reduces errors and operational costs, and makes scaling or changing business processes less risky—factors that can directly affect a company’s profitability and reliability.
