Compact Mobility Unit (CMU)
Move your business forward with an industrial-grade private wireless core
The Nokia Compact Mobility Unit (CMU) performs the mobile packet core functions of your private wireless network for mobile broadband, Internet of Things (IoT), and machine-type communication (MTC) services.
CMU is ideal for enterprises seeking to deploy industrial-grade private wireless networks. It provides all the necessary functions of the mobile packet core (MPC) using field-proven software based on our Cloud Packet Core solution for Communications Service Providers (CSP). With CMU, you get the reliability, scalability, flexibility, and performance you need to meet your business-critical networking requirements for a diverse range of services.
In addition, CMU supports both 4G and 5G radio access network connectivity across licensed, shared (CBRS), and unlicensed (MulteFire) wireless access as well as 3GPP 4G Evolved Packet Core (EPC), 5G non-standalone (NSA) core and 5G standalone (SA) core architectures.
CMU performs these mobile packet core functions:
In LTE and 5G NSA architecture:
- Mobility Management Entity (MME)
- Packet Data Network Gateway (PGW)
- Policy and Charging Rules Function (PCRF)
- Serving Gateway (SGW)
- Home Subscriber Server (HSS)
In 5G SA architecture:
- Access and Mobility Function (AMF)
- Session Management Function (SMF)
- User Plane Function (UPF)
- Authentication Server Function (AUSF)
- Unified Data Management (UDM)
CMU is responsible for the core network functions of a private cellular network implemented in an integrated single appliance, it performs end point authentication, registration and mobility management via MME and AMF, routing, packet forwarding and session management through S/P GW and UPF, end point profile repository, identification and addressing via HSS and AUSF/UDM, and policy control via PCRF.
Feature and benefits
Simple, flexible deployments
CMU simplifies your private wireless network deployment by combining all the essential mobile packet core functions in a pair of HP DL325 Gen10 rack-mounted servers that can fit easily into an IT cabinet or data center. Packaged as a pre-integrated appliance, CMU does not require a network functions virtualization (NFV) infrastructure or orchestration system for lifecycle management.
CMU gives you more flexibility to deploy a private wireless network that meets your unique requirements, offering both centralized and distributed core architectures while by securely maintaining all your business-critical subscriber and operational data on your premises.
CSPs can easily deploy CMU as part of their private-wireless service providing the enterprise dedicated core solution.
Faster Industry 4.0 transformation
CMU accelerates your Industry 4.0 transformation by letting you take advantage of the vast 4G ecosystem to digitalize and automate your operations. CMU supports the non-standalone (NSA) Option 3x configuration as well as the 5G standalone (SA) Core.
To support your business-critical communications you need a network that delivers high-reliability and performance. CMU meets your high availability requirement with hot-standby stateful redundancy and supports edge network configurations for low-latency applications.
Efficient Industrial IoT (IIoT) support
CMU helps your business put the IIoT to work. It provides the scalability, performance and the 3GPP cellular IoT (CIoT) feature you need to support LTE-M and narrowband IoT (NB-IoT) applications efficiently and cost effectively.
