TS.43 Service Entitlement Configuration image

This document 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. The device services currently covered in this document are Voice-over-Wi-Fi (VoWiFi), Voice-over-LTE (VoLTE), SMS over IP (SMSoIP) and On-Device Service Activation (ODSA) of eSIM Companion devices (associated with the requesting device).

The specification leverages the protocol and document presentation described in GSMA PRD RCC.14. In this context, the term “entitlement” refers to the applicability, availability and status of that service (or feature) on a device.

The entitlement configuration is exchanged between a VoWiFi, VoLTE, SMSoIP or eSIM Companion ODSA client on a device and a Service Provider’s Entitlement Configuration Server. Entitlement configuration defines a mechanism for a Service Provider to inform mobile devices of the status of IP Multimedia Subsystem (IMS) network services like VoWiFi, VoLTE and SMSoIP, and in the eSIM ODSA context it defines the interaction between an ODSA client, a client application on a device that entitles and activates a companion device’s subscription, and the Service Provider.
