Cloud Packet Core (CPC)

Deploy a webscale-class evolved packet core (EPC) and 5G core network

Deploy your evolved packet core (EPC) and 5G core (5GC) without limitations using virtualized network functions (VNFs), cloud-native network functions (CNFs), physical network functions (PNFs) and pre-integrated server-based appliances.

Utilize existing wireless and wireline investments to provide multi-access connectivity that is anchored by a virtualized and cloud-native evolved packet core (EPC) and 5G core (5GC) solution.


What is packet core?

The Nokia packet core provides key components needed for a webscale-class evolved packet core (EPC) and 5G core system (5GC). Deploy diverse services and applications without limitations, either on a private or public cloud and with a distributed or centralized architecture.

With its virtualized, cloud-native disaggregated and state-efficient design, the Nokia packet core is well suited to diverse cloud environments. Nokia’s packet core is infrastructure agnostic and independent of the underlying cloud infrastructure used for orchestration, lifecycle management (LCM) and infrastructure resource management.

Multi-terabit packet core user planes can be created using physical network functions (PNFs) realized with the Nokia 7750 service router. Pre-integrated packet core appliances offer network growth, deliver additional functionality and mitigate end of life challenges due to limited cloud infrastructure.

The Nokia packet core can anchor both wireless (2/3/4/5G NSA and SA) and wireline (xDSL, PON, fiber) access technologies, forming a universal adaptive core.

Packet core products

The Nokia packet core consists of the Cloud Mobile Gateway (CMG), Cloud Mobility Manager (CMM) and Cloud Network Resource Director (CNRD). These products provide key components of an evolved packet core (EPC), a 5G core (5GC) and 2G/3G mobile packet core domains for the creation of a single packet core network.

Packet core products

Cloud Mobile Gateway

The Cloud Mobile Gateway (CMG) supports multi-access connectivity by converging multiple mobile packet core gateway functions.

In 4G evolved packet core (EPC) networks this includes the serving gateway/packet data network gateway/ gateway GPRS support node (SGW/PGW/GGSN), policy control enforcement function (PCEF), subscriber services gateway (SSG) providing carrier-grade network address translation (NAT), TCP optimization, firewall and service chain steering capabilities, hybrid access gateway (HAG) for converged service delivery, home agent node (HA), evolved packet data gateway (ePDG) and trusted wireless access gateway (TWAG).

In 5G core (5GC) networks this includes the session management function (SMF) and user plane function (UPF).

Cloud Mobility Manager

The Cloud Mobility Manager (CMM) is a key control plane element of the Nokia packet core solution built to support the growth of diverse services as well as the evolution to a 5G core system (5GC).

In 4G evolved packet core (EPC) networks the CMM provides the mobility management entity (MME) function, and the serving GRPS support node (SGSN) function in 2G/3G mobile packet core networks.

In 5G core (5GC) networks the CMM provides the access and mobility management function (AMF).

Cloud Network Resource Director

The Cloud Network Resource Director (CNRD) provides two 5G core (5GC) network functions: Network Repository Function (NRF) and Network Slice Selection Function (NSSF), as defined in the 3GPP SBA (Service Based Architecture).    

The NRF stores the network function (NF) registration information. It allows NF to act as "Producer" or "Consumer" of services, besides subscribing to services from other network functions.    

The NSSF defines the correct network slice from the list pre-defined ones, to serve a specific device. It also sets the correct NF and resources to serve the requesting device.

Key packet core design principles

Find out how key principles for designing a 5G packet core are necessary for reliability, flexibility and scalability for the architecture to support many different configurations. The areas of maximised throughput and reduced latency, deployment flexibility, state-efficient core network functions and the need to support multi-generational networks/protocols are explained, calling-out the need for a cloud-native approach to win in 5G.

5G packet core security

The move to cloud infrastructure for 5G networks changes how network security, data protection, and privacy should be addressed. Due to 5G architecture complexity as well as specialized protocols and interfaces used in the communications industry, protecting against security threats is well beyond the capabilities of traditional IT security vendors.  

Nokia takes the security built into our products seriously. Our cloud-native 5G Packet Core is designed for privacy and security, with layered protection based on defense-in-depth design and zero-trust principles and tested against 5G-specific use cases. CSPs get full control to secure their 5G services, thanks to the pervasive and automated security management built into our design practices, 5G core software, and dedicated security solutions.

Wireless and wireline convergence

A key network element within the wireline domain, the Broadband Network Gateway (BNG) can be integrated into a universal adaptive core. Utilizing control and user plane separation allows the BNG subscriber management control plane function to be separated from its user plane function.

Nokia’s approach adds the BNG control plane functionality to the packet core’s session management function (SMF) to create a fully converged control plane for both wireless and wireline access that is unique within the industry.

Packet core customer references

Nokia’s Cloud Packet Core has been selected by service providers around the globe for its reliability, scalability, flexibility and performance that is needed to meet their requirements and economics for today and the future.
