1  Scopep. 6

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. This work covers both PCEF and TDF.
  • 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.

3  Definitions and abbreviationsp. 6

3.1  Definitionsp. 6

For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply.
A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Sponsored data related rule:
It includes 1) the PFD information identifying sponsored data packets, 2) correlation identifier, 3) charging key.
Sponsored data related information:
It includes the 1) correlation identifier, 2) charging key.
SDC information:
The information of sponsored data connectivity defined in clause 5.2.1 in TS 23.203.
Sponsored data service:
Consuming some certain kind of traffic for free.
Application Service Provider:
the business entity that provides the service. See TS 23.203.
Packet Flow Description:
A template to enable detection of IP-flows to identify a service provided by an ASP. The template includes, for example, a 3-tuple including protocol, server side IP address and port number or the significant parts of the URL to be matched, e.g. host name.
Sponsor:
The business entity taking all or part of the cost of the connectivity. The sponsor has a business relationship with the MNO. The Sponsor may restrict usage to certain users. See TS 23.203.
Sponsored Data Connectivity Information:
It consists of a) the identification of the sponsor and b) the identification of the Application Service Provider (ASP) and its applications (Application Identifier(s) and optionally c) a usage threshold to limit the amount of data or time the user connectivity is sponsored. See TS 23.203, clause 6.2.1 for the definition of sponsored data connectivity information.

3.2  Abbreviationsp. 7

For the purposes of the present document, the abbreviations given in TR 21.905 apply.

4  Architectural Assumptions and Requirementsp. 7

It shall be possible for the 3rd party service provider to add/update/delete information related to sponsored data connectivity for provisioning in the operator network. This information should be validated within operator's network before being accepted in the operator's network.
The provisioning of the information shall be independent of any user and of any IP-CAN session.
The information related to sponsored data connectivity shall be provided towards the operator network in a secure manner.
The enhancements to sponsored data functionality shall be applied either for all subscribers, or for a group of subscribers as nominated by the sponsor.
