    N-Squared Software N2SCP CAP/INAP Protocol Conformance Statement Version 2020-08 N2SCP CAP/INAP Protocol Conformance Statement Version 2020-08 1 Document Information 1.1 Scope and Purpose This document describes the implementation of the CAMEL (including INAP variants) protocol for real- time SCP flows for voice interaction control using the N-Squared Service Control Point (N2SCP) family of applications. The N2SCP family of applications includes: • N2DSG-SCP (CAMEL/Diameter Signalling Gateway) • N2NP-SCP (Number Portability translation application) • N2ACD-SCP (Advanced Call Distribution application for Toll-Free and other routing services) • …plus other custom SCP services that may be developed. All of these applications use the N2SCP framework. They do not typically use all of the framework. Please refer to the relevant technical guide ([R-N2-DSG-TG], [R-N2-NP-TG], [R-N2-ACD-TG]) for application-specific scenarios and configuration parameters. This document assumes a working knowledge of the relevant CAP/INAP and other telephony concepts, including the standard CAP/INAP interactions between an SCP, an SSP, and an SRP (or Intelligent Peripheral). 1.2 Definitions, Acronyms, and Abbreviations Term Meaning AC Apply Charging ACR Apply Charging Report ARI Assist Request Instructions ASN.1 Abstract Syntax Notation One AT Activity Test BCSM Basic Call State Model CAMEL Customized Applications for Mobile Network Enhanced Logic CAP CAMEL Application Part CIR Call Information Request/Report CTR Connect To Resource CWA Continue With Argument DFC

    Message Automation & Protocol Simulation (MAPS™) Multi-Interface, Multi-Protocol Simulator - TDM, IP, 2G, 3G, 4G, 5G Overview GL's Message Automation & Protocol Simulation (MAPS™) is a protocol simulation/ emulation and conformance test tool that supports a variety of protocols such as MGCP, SIP, MEGACO, SS7, ISDN, GSM, CAS, MC- MLPPP, MAP, LTE, UMTS, SS7 SIGTRAN, ISDN SIGTRAN, SIP I, Diameter, MAP IP, 5G N1 N2, N4 and others. This protocol emulation tool covers solutions for both protocol simulation and analysis. The product also supports RTP, TDM, TRAU GSM, and Mobile traffic simulation over various network. The application includes various test plans and test cases to support the testing of real- time entities. Along with automation capability, the application gives users the unlimited ability to edit messages and control call scenarios (message sequences). "Call Scenarios" are generated through scripts. MAPS™ is designed to work on TDM interfaces as well as on the Ethernet interfaces. TDM signaling protocols such as SS7, ISDN, CAS, MC-MLPPP, MAP, IUP, CAP, INAP, GSM, and FXO/FXS operate over TDM networks, whereas SIP, MEGACO, and MGCP operate over IP networks. MAPS™ supports 3G & 4G mobile protocol simulation such as LTE (S1, eGTP) interfaces, LTE Diameter [S6a, S6d, S13, Cx/Dx, Gx, Rx, SLg, SLh], INAP IP (ANSI, ITU), CAP IP (ANSI, ITU), GSM A over IP, SKINNY, MAP IP, BICC IP, GPRS, and UMTS (IuCS, IuPS, IuH) over IP. MAPS™ architecture supports both Binary and Text Based Protocol Simulation. MAPS™ also supports Location Services (LCS) simulation for positioning mobile devices. Simulates SLg, SLh interfaces (GMLC, MME, HSS), Lg, Lh interfaces (GMLC, MSC, SGSN, HLR), SLs interface (MME, E-SMLC) and Lb interface (MME, SMLC) and interfaces implementing positioning functionality in a cellular network.

  • SS7 Signalling in Mobile Networks – 3 Days
    SS7 Signalling in Mobile Networks – 3 days CONTENTS The SS7 Signalling in Mobile Networks course explains and describes the world’s most widespread inter-exchange signalling system used in fixed and mobile telecommunication today: Signalling System No 7. It provides the basic ideas and structure of the SS7 protocol stack. Different aspects of various signalling protocols and signalling applications in the telecommunications world are covered. There are a few detailed examples from both mobile and fixed networks. The course focus is on ITU SS7 and GSM/UMTS core network protocols that are based on SS7 system. The participants will also gain a general understanding on how to interpret log files and traces taken from live networks. PREREQUISITES General telecom and basic signalling knowledge is recommended. For background knowledge, we recommend the Apis’ course 3GPP Mobile Systems Overview. SS7 Introduction • The overview of the SS7 system • The definition and structure of the SS7 signalling network: SP, STP, SL, LS, etc. • The logical division of SS7: MTP and User Parts • Use of SS7 protocol in 2G and 3G mobile networks and fixed networks • Overview of various SS7 protocols MTP - Message Transfer Part • The functions of the different MTP levels • The structure and functions of MTP signal units, signalling link states and link management functions • MTP 3 message handling – addressing, routing, load sharing, and distribution • The overview of Signalling Network Management and Testing functions ISUP - ISDN User Part • Use and functions of
