The TSG Intersystem Operations (TSG-N) is responsible for the specifications of the Core network part of systems, based on 3GPP2 specifications.
Specifically, it has a responsibility for:
- core network internal interfaces for call associated and non-call associated signaling;
- management of work items placed under its responsibility;
- validation and verification of specification text it develops.
More specifically, TSG-N will address the following areas of work:
- evolution of core network to support interoperability and intersystem operations;
- UIM support (detachable and integrated);
- support for enhanced privacy, authentication, encryption and other security aspects;
- VHE (Cirtual Home Environment);
- support for new supplemental services (including ISDN interworking);
- optimal interoperability specificiation for international roaming (e.g., selection of required parameters options);
- new features for internal roaming (global emergency number, optimal routing);
- IMT-2000 issues, as necessary, to ensure support of the ANSI-41 family member.
