Intelligent Network? Along an example in this chapter you will learn what an Intelligent Network is, what it is used for, and what its goals are. Items covered include: • the Prepaid Service as an example for the usage of IN • introduction of the main implementation concepts and the main subsystems The IN product of Siemens is named IN@vantage which also is named IN Version 7a. Prede- cessor Versions have existed up to V6.2 and V7b (b because of its Bellcore based architectu- re). With V7a the IN system has become completely redesigned based on the so called @vantage architecture. This course document is based on the actual Version V7a. IN Training Center IN @ INTRO for COMCEL Colombia Page 1-3 IN Introduction V7a Intelligent Network 1.1 Example: Prepaid Service (PPS) Prepaid Service is based on the principle of on-line charging. The subscriber has to book (and load, if this is not automatically following from the booking) an account and only then can per- form calls. During the calls the balance is continuously debited. If the balance is below a certain limit no calls can be set up. When the account balance reaches zero the actual call will be inter- rupted. The subscriber can recharge his account. The service can be seen as a kind of virtual telephone credit card. The benefit of the Service Provider is the guaranteed payment. No post-processing of billing is required. This service is available for mobile and fixed networks. Core Features Prepaid credit account: the subscriber pays before he can make calls, he loads certain a- mounts of money to his account at the system. Online charging during call: the system decreases the account balance during or after the call. Recharging: to

    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.
