The present document identifies the impact on the NGN in achieving compliance to the data retention directive [i.1]. The present document makes a number of recommendations to operators and manufacturers that may be sufficient to ensure compliance, and identifies where future standardisation may be required. The present document applies to TISPAN NGN services as specified by TR 180 001 [i.12] (for release 1 specific capabilities) and TR 180 002 [i.13] (for release 2 specific capabilities), and where the NGN user is identified as specified in TS 184 002 [i.11].The present document is structured in the following way:
• NGN analysis with respect to Data Retention:
– annex containing an analysis of the existing Directive and the available provisions in the NGN;
– annex providing a comparison of terms between Directive and NGN.
• Identification of the data that is expected to be retained in the NGN under the DR Directive and a mapping to determine if the data is available in the NGN. The present document does not define the handover domain which is specified in TS 102 657 [i.2] nor does the document cover any conformance aspects relating to IMS. However where other standards bodies are directly impacted by the DR Directive in the NGN the present document identifies in outline form the affected publications from such SDOs. The present document does not address the application of Data Retention in Customer Premises Networks (CPN) or Next Generation Corporate Networks (NGCN).
