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.

COMAC EVOLUTION
Multi-Access Co-Existence3GPP cellular and broadband access sharing the same infrastructure and
edge cloud control and orchestration
User-Plane ConvergenceConverging the user planes of 3GPP RAN CU, 3GPP Core and BNG
OMECUse-case optimized,
disaggregated, open source 3GPP core
Control-Plane ConvergenceConverging control plane functions of authentication, subscriber management, session management, etc.
COMACPlatform hosting converged user and control planes with SDN-control, FCAPS-capable edge services mediation with global orchestration connectivity

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
