Cloud Mobile Gateway

Get the flexibility, scale, and performance you need for enhanced broadband, uRLLC and 5G services on any cloud.

What is Cloud Mobile Gateway?

The Nokia Cloud Mobile Gateway performs gateway and related functions within the Packet Core Network. It is built to address the growth of enhanced mobile broadband and deliver new uRLLC connections, Internet of Things (IoT), machine-type communications (MTC), and 5G services.

With the Cloud Mobile Gateway, you get the flexibility, scale, capacity, and performance you need to support more users, devices, and services over licensed, unlicensed, or shared wireless and fixed access.


Cloud-native design

Cloud-native design brings a modern, dynamic, Kubernetes based environment for applications. It allows the implementation of newest technologies like AI/ML and Network Exposure, taking networks to a next level in terms of performance, automation and services.

Our cloud-native software design supports control/user plane separation (CUPS) architecture, software disaggregation, and state-efficient processing. It also provides a common data layer that improves resource utilization for network functions virtualization (NFV) and lowers total cost of ownership (TCO).  

Mobile gateway functions supported by Cloud Mobile Gateway:

  • Serving Gateway (SGW)
  • Packet Data Network Gateway/Gateway GPRS Support Node (PGW/GGSN)
  • Home Agent (HA) for 3GPP2 cellular access
  • User Plane Forwarding Function (UPF)
  • Network Function Repository Function (NRF)
  • Network Slice Selection Function (NSSF)
  • Non-3GPP Interworking Function (N3IWF)
  • Evolved Packet Data Gateway (ePDG) for non-3GPP (Wi-Fi) untrusted access
  • Trusted Wireless Access Gateway (TWAG) for non-3GPP (Wi-Fi) trusted access
  • Subscriber Services Gateway (SSG):
    • Enhanced Traffic Detection Function (TDF) and application awareness for value-added, high-touch services
    • Hybrid Access Gateway (HAG) for converged service delivery across wireless and fixed access

Deployment flexibility: any cloud

The Cloud Mobile Gateway can also be implemented on pre-integrated and modular server-based appliances or cloud-native virtualized network functions (CNFs). It can also be combined with our industry leading PNF mobile gateways to deliver high packet processing and user plane forwarding performance for high-speed services.  

All the Cloud Mobile Gateway deployment options share a common network management system with the Nokia packet core functions. This allows you to right-size your deployment to address diverse service requirements and economics.  

The Cloud Mobile Gateway enables the evolution to a 5G Core by supporting both non-standalone and standalone deployment options and a services-based architecture. It allows you to allocate network resources to a specific service type or enterprise through dedicated core and network slicing capabilities.

Benefits and features of Cloud Mobile Gateway

Improved resource efficiency

  • Supports CUPS architecture, which allows for independent scaling of control or user plane resources to meet individual service requirements
  • With a state-efficient design that dramatically increases subscriber and device connectivity
  • Maximizes resource utilization and reduces network signaling by using a common data layer to store session state information

Increased flexibility and reduced network complexity

  • Disaggregates software into modular components to enable independent scaling and placement that eliminates stranded or underutilized resources
  • Supports centralized and distributed architectures for increased deployment flexibility and optimal resource placement
  • Reduces network complexity by providing a common software base that supports a broad range of mobile gateway functions and access types

Reduced network operational costs

  • Simplifies network engineering and planning by combining multiple mobile gateway functions into a single instance
  • Reduces operation and maintenance (OAM) costs with simplified IT and data center operations, including a common element and network management system (EMS/NMS)
  • Can be deployed within third-party virtualized network environments and NFV infrastructures

Advanced network reliability and redundancy

  • Delivers field-proven reliability with a range of configurable resiliency models
  • Uses cloud-based protection schemes to improve network resource efficiency and ensure high network availability
  • Provides a geo-redundant configuration option to support additional network resiliency

Faster time to market

  • Enables rapid deployment of mobile gateways that are correctly sized for the service and service provider
  • Dynamically adjusts capacity when and where it's needed through automation and cloud lifecycle management
  • Supports tailoring of new services for targeted customers with the SSG function

The cloud mobile challenges facing service providers

CSPs are heading towards 5G and require a clear evolution path and a solution that facilitates:


  • Extreme performance for CapEx optimization, maximizing hardware utilization while ensuring services like uRLLC.
  • A convergent solution supporting mobile (2G/3G/4G/5G)  and fixed access for network simplification.
  • A Cloud agnostic solution with flexible architecture: CMG software is strongly adherent to 3GPP standards, proven to run on different cloud platforms and orchestration systems. Furthermore, it can be deployed on multiple capacity appliances, ensuring the flexibility CSP wants to build the network that meets their needs.

Why choose Nokia’s Cloud Mobility Gateway?

Cloud-native design

CMG is designed bottom up for cloud-native, integrating several open-source services and enabling a modern and dynamic environment for new applications, expanding the monetization possibilities. Furthermore, it implements CNF life cycle management operations (installing, healing, scale-in, scale-out and AI-based) and uses central DevOps/DelOps aspects for integration, delivery and image storage.

Multi generation and multi-access

It is a convergent solution, supporting mobile (2G/3G/4G/5G)  and fixed access for network simplification, and also supports EPC with a clear evolution path to 5G SA.

Extreme high-performance and uRLLC

The Nokia solution uses vFP (Virtual Forwarding Path), which optimizes the use of vCPU and prevents bottlenecks, ensuring high performance and enabling new 5G services.

Any cloud architecture and network scalability

CMG is proven on any cloud architecture: on-premises, edge, regional central private, hybrid and public. This will meet any deployment requirement CSP may need.
