1  ScopeWord‑p. 7

The present document provides a study into providing a SIP-I based Nc interface (G)MSC-S - (G)MSC-S as an alternative to the existing BICC definition. The document covers the functional description, network architecture and protocol definition for the SIP-I based solution. The contents of this report when stable shall be moved into a Technical Specification 3GPP TS ab.cde along with modifications to existing specifications.
