CONVERGED MULTI ACCESS & CORE

OĞUZ SUNAYCHIEF ARCHITECT FOR MOBILE NETWORKING

BIG 5G EVENT MAY 6, 2019

COMAC

• Develop a modular, cost-efficient platform and components with well-defined interfaces to enable access and core networks, including

– A streamlined, simple and cost-efficient implementation of 3GPP cellular core,

– A converged user plane function (CUPF) that unifies user plane components of fixed broadband network gateway, 3GPP cellular core and virtualized 3GPP cellular radio access that would be hosted at the multi-access edge cloud,

– A suite of control plane functions/applications that would intelligently be engaged to ensure proper, and standards compliant and programmatic control of CUPF,

– Access and Core Controllers that intelligently and programmatically map CUPF with the corresponding suite of control plane applications.

MULTI-CLOUD CONNECTED MULTI-ACCESSEDGE Key Takeaways

SDN-Based Programmatic Control of AccessCORD’s SDN controller is the perfect choice to

enable simultaneous programmatic control of

subscriber management for broadband access

and network slicing management for mobile

access.

Multi-Vendor PlatformCORD presents a mobile edge platform that

can be constructed using hardware and

software from multiple vendors – ensuring a

break from vendor lock-in

Open Source Driving Telco TransformationOpen source is a catalyst for the telco community to

come together to deliver a comprehensive and highly

integrated demonstration for the mobile edge

Multi-Cloud ConnectivityCORD allows connectivity to central clouds,

enabling VNF-based service graphs as well as

OTT service components distributed across

such hybrid clouds

Open Source 3GPP CoreONF’s OMEC is a production-grade, release 13, CUPS-

compliant core network platform that is tailored for

use cases such as IoT. Containerized OMEC

components can be natively hosted on CORD.

Multi-Access EdgeCORD, designed to simultaneously support

multiple access technologies is the perfect

platform for the envisioned access and core

convergence with COMAC
