+= 5G system TS29514 Npcf Protocol Modules for TTCN-3 Toolset with TITAN, Description
+:author: Gábor Szalai
+:toc: left
+
+== About This Document
+
+This is the description for the 5G system TS29514 Npcf protocol module. The 5G system TS29514 Npcf protocol modules are developed for the TTCN-3 Toolset with Titan. 
+
+== Functionality
+
+The 5G system TS29514 Npcf protocol module implements the object structures of the 3GPP TS 29514 v15.1.0<<_5, [5]>> in a formalized way, using the standard specification language TTCN-3. This allows defining of test data (templates) in the TTCN-3 language and correctly encoding/decoding messages when executing test suites using the Titan TTCN-3 test environment.
+The 5G system TS29514 Npcf protocol module uses Titan’s JSON encoding <<_3, [3]>> and hence is usable with the Titan test toolset only.
+
+=== System Requirements
+Protocol modules are a set of TTCN-3 source code files that can be used as part of TTCN-3 test suites only. Hence, protocol modules alone do not put specific requirements on the system used. However, in order to compile and execute a TTCN-3 test suite using the set of protocol modules the following system requirements must be satisfied:
+
+* Titan TTCN-3 Test Executor version CRL 113 200/6 R5A (6.5.pl0) or higher installed. For Installation Guide see <<_2, [2]>>. Please note: This version of the test port is not compatible with Titan releases earlier than CRL 113 200/6 R5A.
+
+===	Installation
+The set of protocol modules can be used in developing TTCN-3 test suites using any text editor. Since the 5G system TS29514 Npcf protocol is used as a part of a TTCN-3 test suite, this requires TTCN-3 Test Executor be installed before the module can be compiled and executed together with other parts of the test suite. For more details on the installation of TTCN-3 Test Executor see the relevant section of <<_2, [2]>>.
+
+== Interface description
+
+=== Encoding/decoding and other related functions
+This product also contains encoding/decoding functions, which assure correct encoding of messages when sent from Titan and correct decoding of messages when received by Titan. 
+
+==== Implemented encoding and decoding functions

+f_dec_EventsSubscReqData(in octetstring stream, out EventsSubscReqData pdu) return integer 
+----
+
+== Usage
+
+The protocol module provides abstract data types for JSON objects used by the services defined in the standard <<_5, [5]>>. The protocol module provides encoder and decoder functions for the JSON objects. The decoder function validates the received JSON object based on the JSON schema as well. Only the validated JSON value is decoded.
