WI Acronym:  FS_SDCI
Rapporteur:  Mr. Xu, YangChina Unicom

The scope of the present document is to study sponsored data connectivity improvements including:
  • Solutions for sponsored data connectivity to cope with the increasing configuration update capacity requirements, possible maintenance difficulties and long deployment cycle. This work covers both PCEF and TDF.
  • Solutions for provisioning of the information needed to support detection while traffic is encrypted in the operator's network for sponsored data services. This work includes identification of the required information.
  • Introduce sponsored data connectivity functionality to TDF as currently exists in case of PCEF. Normative specifications should be developed based on the evaluations and conclusions of this study item.
This work covers both PCEF and TDF.
