5G N21 Interface Emulation
MAPS™ 5G-N21 can emulate and test Unified Data Management (UDM) and Short Message Service Function (SMSF) entities in 5G Core Network (5GC) elements via the service-based N21 interface.Brochure
MAPS™ 5G N21 interface can emulate Unified Data Management (UDM), within the 5G Core Network offering services to Short Message Service Function (SMSF) via the service-based N21 interface.
Supports the following services:
GL has enhanced its MAPS™ protocol emulation tool to emulate multi-protocol and multi-interface offering a complete range of test solutions, covering the entire 2G, 3G, 4G and 5G network.
By mimicking real-world customer behavior in lab environments, our solutions allow mobile operators and equipment manufacturers to verify their 5G networks before deployment.
GL also provides a GUI based Multi-Protocol Analyzer for on-line capture and decode of the signaling in real-time both during tests and as a stand-alone tracer for live systems.
- Emulate UDM and SMSF elements
- Supports Nudm_SubscriberDataManagement Services (Get, Subscribe, ModifySubscription, Unsubscribe and Notification operations) and Nudm_UEContextManagement Services (SMSF Registration and Deregistration operations)
- Services use REST APIs based on HTTP and JSON data format
- Supports TLS and TCP transports
- Supports scripted call generation and automated call reception
- Supports customization of call flow and message templates using Script Editor
- Ready-to-use scripts for quick testing
- Provides Call Statistics and Events Status
- Generate multiple subscribers using CSV profiles
- Automation, Remote access, and Schedulers to run tests 24/7

5G N21 Interface Procedures
In 5G N21 interface, MAPS™ acts as either UDM to test SMSF or SMSF to test UDM emulating the Nudm_UEContextManagement and Nudm_SubscriberDataManagement Service Operations.
The below figures depict the Call Generation and Reception of 5G N21 interface between UDM and SMSF.
Please Note: The XX in the Item No. refers to the hardware platform, listed at the bottom of the Buyer's Guide, which the software will be running on. Therefore, XX can either be ETA or EEA (Octal/Quad Boards), PTA or PEA (tProbe Units), UTA or UEA (USB Units), HUT or HUE (Universal Cards), and HDT or HDE (HD cards) depending upon the hardware.
