Sentinel VoLTE 4.1 :: Sentinel VoLTE Architecture

What does MMTel do?

MMTel (Multi-Media Telephony applications) delivers the core call-control services for voice and video communications, as well as the supplementary services for VoLTE.

Services General information

Services	General information
GSMA required Supplementary Services	Rhino Sentinel VoLTE delivers these services in an LTE/IMS network, following the GSMA IR.92 (v9.0) and IR.94 (v10.0) standards. With the exception of Message Waiting Indication (MWI), all IR.92 services are supported within Sentinel VoLTE. Using Sentinel Create, it is possible to extend the feature set to very easily include other services. Anonymous Call Rejection (ACR) is also supported, even though it is not an IR.92 service.
Flexible Alerting	3GPP defines Flexible Alerting in TS 24.239 and the flexible alerting subscriber data schema is defined in TS 24.239 and TS 29.364. The service allows the creation of a group of member identities bound to a single number, called the `Pilot Number`. When a call to the `Pilot Number` is identified, VoLTE will alert all the members of the group and the caller is bound to the first member of the group that answers the call.
Explicit Communication Transfer	3GPP defines Explicit Communication Transfer in TS 24.629. The service allows a member in a communication dialogue called the `transferor` to transfer their role in the dialogue to another user called the `transfer-target`. The member that remains in the dialogue during the transfer is called the `transferee`.
Session Transfer to Own Device	Is a service that allows an existing originating or terminating session to be transfered to another device. The target device is the one that pulls the session.

Is a service that allows an existing originating or terminating session to be transfered to another device. The target device is the one that pulls the session.
