- Open-RAN.org - movement by MNOs to separate hardware and software and create open interfaces inside the RAN - many CN members, trying to make their way back in after the disavowal of CN companies in US/EU
GSMA service provisioning
IMS service configuration is defined in GSMA PRD IR.51 and GSMA PRD IR.92.
The service configuration procedure between clients and the Service Provider’s configuration server described in GSMA PRD RCC.14 (including authentication).
- GSMA TS.43 Service Entitlement Configuration
- Describes the procedure for configuration of a device-based service performed during the entitlement verification step of the service or during the activation of that service
- Services are IMS based: Voice-over-Wi-Fi (VoWiFi), Voice-over-LTE (VoLTE), SMS over IP (SMSoIP) and On-Device Service Activation (ODSA)
- Entitlement configuration is usually triggered by the device or client and the user is not aware of an entitlement configuration process taking place.
- It is then preferable for the entitlement configuration server to rely on authentication mechanisms like “User Authentication via HTTP Embedded EAP-AKA” which does not involve user interactions.
- In case access to the device’s SIM data is not possible (which would prevent authentication based on EAP-AKA), authentication following the OpenID or OAuth 2.0 procedure is the preferred alternative.
