47、service provides a party involved in a communication to transfer that communication to a third party. Procedures for the ECT AS regarding operator determined barring (ODB) are defined in 3GPP TS 24.315 12. 4.2 Description 4.2.1 General description The explicit communication transfer (ECT) service pr
48、ovides a party involved in a communication to transfer that communication to a third party. There are three actors active in a transfer, they are acting in the following roles: transferor: the party that initiates the transfer of the active communication that it has with the transferee; transferee:
49、the party which stays in the communication which is transferred; transfer target: the party which the communication is transferred to and which replaces the transferor in the communication. There are two initial situations in which transfer shall be possible: - the transferor has no ongoing consultation communication with the transfer target (blind/assured transfer), then either: a) the transferor wants to perform the transfer without any further action on the transfer operation (blind transfer); or b) the transferor wants to ha
