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 messages that set up calls, register subscribers 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 as top-tier telecom risk.

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

To place GSMA Open Gateway in the wider telecom-security picture, review SOC, 1G, 5G SBA, AAA, ACL and Any-Time Interrogation (ATI) — each entry cross-references back to this page so you can walk the topic in either direction.
