1  ScopeWord‑p. 5

The present document studies 3GPP system enhancements e.g. CS or PS domain specific access control to cope with several network overload and failure situations. This feasibility study also identifies the potential technical solutions for UTRAN and GERAN access control and overload protection.
Clause 4 reviews the various congestion and node failure scenarios: these will be used to derive any new functional requirements.
Clause 5 identifies the new functional requirements.
Clause 6 contains a presentation of the potential technical solutions.
Clause 7 conclusion.
