Intelligent Network (IN); Intelligent Network Capability Set 1 (CS1) extension; Intelligent Network Application Protocol (INAP); Part 1: Protocol specification for Camel Phase 2

To produce a version of INAP for CS2 Extension in order to cover the protocol procedures for the Camel Phase 2 requirements suitable for implementation in Europe. Close co-operation must be ensured with SMG3 with regard to Camel Phase 2 requirements. The specification should also address aspects of interaction between IN structured networks. The Camel Phase 2 defintions should be fully compatible with the existing CS1 INAP.
