Cloud Packet Core (CPC)

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

Complete evolved packet core and 5G core deployment flexibility with virtualized network functions (VNFs), cloud-native network functions (CNFs), physical network functions (PNFs) and pre-integrated modular server-based appliance solutions. Nokia’s packet core allows service providers to deploy without limitations and host whatever they envision to profit from opportunities.

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

What is packet core?

The Nokia packet core provides key components needed for a webscale-class evolved packet core (EPC) and 5G core network enabling service providers to deploy diverse services and applications without limits, 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. It can be deployed as a virtual evolved packet core (EPC) or 5G core using virtualized network functions (VNFs) and cloud-native network functions (CNFs). Our mobile 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 to those service providers that do not have a network function virtualization infrastructure (NFVI).

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, realized with the Nokia CMG). These products provide key components of an evolved packet core (EPC), a 5G core and 2G/3G mobile packet core domains, allowing service providers to build a single packet core network.

Cloud Mobile Gateway

The Cloud Mobile Gateway (CMG) supports multi-access connectivity by converging multiple mobile packet core gateway functions while offering various virtualized and cloud-native configuration options that provide deployment flexibility. The CMG can be deployed as a standalone network function or in various combinations.

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 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 packet core solution built to support the growth of broadband and enterprise services as well as the evolution to a 5G core.

The CMM provides the access and mobility management function (AMF) in 5G core networks, the mobility management entity (MME) function in 4G evolved packet core (EPC) networks, and the serving GRPS support node (SGSN) function in 2G/3G mobile packet core networks. 

Cloud Network Resource Director

The Cloud Network Resource Director (CNRD, realized with the Nokia CMG) provides 5G core network functions that include the network repository function (NRF) and network slice selection function (NSSF).

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.
