Defining signalling requirements and
protocols for:
- telephone
and N-ISDN basic and supplementary services;
- B-ISDN
and multimedia services;
- user
mobility and terminal mobility for UPT and mobile (FPLMTS) services;
- access
and network security;
- control
of transmission equipment (e.g. echo controllers);
Using technologies such as:
- intelligent
network;
- Signalling
System No. 7, including MTP, ISUP, B-ISUP, SCCP and TC;
- Digital
Subscriber Signalling 1 (DSS 1) for N-ISDN;
- Digital
Subscriber Signalling 2 (DSS 2) for B-ISDN;
- data
link layer for DSS 1 and DSS 2;
- ATM
adaptation layer;
Supported by framework and methodology
studies on:
- signalling
and protocol framework for an evolving environment;
- unified
functional specification methodology.
Study
Group 11 is the Lead Study Group for FPLMTS, recognizing that, inter
alia, FPLMTS service
aspects are studied by Study Group 2.
Study
Group 11 should provide technical advice to the TSB concerning the allocation of
signalling area/network codes.
Close
coordination with Study Groups of ITU-T and ITU-R as well as outside forums and consortia
would continue to be maintained.
