21、e 15 ETS 300 374-1 : 1994 1 Scope This first part of ETS 300 374 defines the Intelligent Network Application Protocol (INAP) required for support of Capability Set 1 (CS1). It supports interactions between the following three Functional Entities (FES), as defined in the Intelligent Network (IN) func
22、tional model: - Service Switching Function (SSF); - Service Control Function (SCF); - Specialized Resource Function (SRF). The scope of this ETS is the further development of the INAP for both the Integrated Services Digital Network (ISDN) and Public Switched Telecommunications Network (PSTN). It is
23、 intended as a guide to implementors and network operators to ensure interworking between different manufacturers equipment for the following IN CS1 defined interfaces (SCF-SSF and SCF-S RF) . As this ETS is intended for the early introduction of IN in the existing ISDN/PSTN, only simple solutions a
24、re assumed for solving the service interaction problems between IN and ISDN/PSTN. NOTE: More sophisticated solutions for the service interactions between IN and the ISDN/PSTN environment should be studied in the scope of future versions of INAP and the ISDN/PSTN signalling standards. 2 Normative ref

The SACF/MACF rules are de
39、fined in prose. The operation definitions are in Abstract Syntax Notation 1 (ASN.l, see CCITT Recommendation X.208 i1411, and the actions are defined in terms of state transition diagrams. Further guidance on the actions to be performed on receipt of an operation can be gained from Clause 6 and from
40、 the relevant detailed procedures in Clause 7. The INAP is a Remote Operations Service Element (ROSE) user protocol (see CCITT Recommendations X.219 1161 and X.229 171). The ROSE protocol is contained within the Digital Subscriber Signalling System No. One (DSS1, see ETS 300 196-1 41) and the Compon
41、ent Sublayer of the Transaction Capabilities Application Part (TCAP, see ETS 300 287 51). NOTE 1: At present, the ROSE Application Protocol Data Units (APDUs) are conveyed in Transaction sublayer messages in Signalling System No.7 (Signalling System No.7) and in the Q.931 FACILITY and Call Control m
42、essages in DSS1 (see ETS 300 403-1 81). Other supporting protocols may be added at a later date. NOTE 2: The INAP (as a ROSE user) and the ROSE protocol have been specified using ASN.l. At present, the only standardized way to encode the resulting PDUs is the Basic Encoding Rules (see CCITT Recommen
43、dation X.209 i1 51). 4.2 Example physical scenarios The protocol supports any mapping of functional to Physical Entities (PES), see ETS 300 348 61 (ITU-T Recommendation 0.1 21 5). It is the responsibility of network operators and equipment manufacturers to decide how to co-locate FES to the best pos
44、sible advantage as this may vary between manufacturers and between network operators. Therefore the protocol is defined assuming maximum distribution (.e. one PE per FE). The figures depicted in this subclause show how INAP would be supported in an Signalling System No.7 network environment. This do
45、es not imply that only Signalling System N0.7 may be used as the network protocol to support INAP. When TCAP appears in one of the following figures, it is to be understood as representing the TCAP functionalities associated with a single dialogue and transaction (as opposed to a TCAP entity). For e
46、ach physical scenario, the typical SRF control procedures to be applied are shown in subclause 7.3.5. The interface between remotely located SCF and SDF is INAP using TCAP which in turn uses the services of the connectionless SCCP and MTP (see figure 1). The SDF is responsible for any interworking t
47、o other protocols to access other types of networks.
