GSMA Open Gateway

A GSMA industry initiative providing a framework for standardized network API exposure that enables developers and enterprises to access operator network capabilities. Open Gateway APIs are defined through the CAMARA project and cover authentication, fraud prevention, location services, quality-on-demand, device management, edge computing, and carrier billing. The framework aims to enable federated API access across multiple operators through standardized interfaces.

GSMA Open Gateway in context

Signaling protocols carry the control-plane instructions that set up calls, register subscribers, hand over sessions and route SMS. SS7, Diameter, GTP-C and SIP are the four dominant families, and interconnect exposure of any of them is treated by GSMA FS.11 / FS.19 / FS.20 as a top-tier telecom risk.

Security controls in telecom span signaling firewalls (SS7/Diameter/GTP screening at the network edge), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both the packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36 and, in Europe, NIS2 sectoral rules.

To place GSMA Open Gateway in the wider telecom-security picture, review 5G SBA, CAMARA Project, FASG, IN, KPI and Network Exposure Function (NEF).
