Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN); Prevention of Unsolicited Communication in the NGN (V3.1.1)
The present document describes a Prevention of Unsolicited Communications (PUC) service for use in the NGN. The present document defines the method by which a terminating party is prevented from receiving UC. The present document addresses the NGN objectives (including the legal implications) that are met by the PUC service and identifies the requirements to be met by the NGN for PUC. The present document derives from TR 187 009 [i.11]. The present document covers deployment of the NGN in the following scenarios: ? Home networks@ focusing on interconnection from the CNG with the NGN and interaction between the CNG and CND. And proposing UC detection handling on the CNG. ? Enterprise networks@ focusing in interconnection between the NGCN and the NGN and the interaction between the UE and the NGCN and NGN. And proposing UC detection and handling for NGCN devices. ? Single user scenario@ focusing on interconnection between the UE and the NGN and proposing a UC detection handling framework for entities of the NGN. NOTE: The specification of PUC for Common IMS are defined in 3GPP 33.937 [i.12].
