1 A Common Framework for Integrating Wireless, Wireline and Internet Networks
JAIN FOR MAP PROJECT GROUP: Maurizio Bonuccelli Piero Lauri Francesca Martelli Renata Bandelloni 10 novembre 2018 PISATEL

2 Cellular Systems The geographic area is divided into cells
Each cell has a Base Station managing the communications A set of cells managed by a single MSC is called Location Area MSC VLR HLR land link land link VLR MSC Base Station Radio link MSC Mobile Switching Center VLR Visitor Location Register HLR Home Location Register 10 novembre 2018 PISATEL

3 Functional Planes TRASMISSION: manage the trasmissive medium
COMMUNICATION MANAGEMENT: provides the means to control user communications MOBILITY MANAGEMENT: manage the databases for the location of any mobile station RADIO RESOURCE MANAGEMENT: provides a stable link between MS and MSC CM MM RR TRASMISSION 10 novembre 2018 PISATEL

6 The SS7 Signaling protocol
TCAP (TRANSACTION CAPABILITIES APPLICATION PART): provides the capability to exchange information between applications using non-circuit related signaling SCCP (SIGNALING CONNECTION CONTROL PART): realyze both connectionless and connection oriented network service and provides additional functions such as Global Title Translation MTP (MESSAGE TRANSFER PART): three levels corresponding to the OSI physical layer, data link layer and network layer. ISUP (ISDN User Part): used to setup and release calls MAP (Mobile Application Part): used for signaling related to a number of services MTP1 MTP2 MTP3 SCCP TCAP MAP ISUP Call-related signaling No call-related signaling 10 novembre 2018 PISATEL

7 Services of the MAP protocol
10 novembre 2018 PISATEL

8 GSM MAP Service Framework
The GSM entities communicate with each other to carry out some service, through MAP dialogues by invoking one of four MAP primitives: REQUEST INDICATION RESPONSE CONFIRM 10 novembre 2018 PISATEL

9 Common services of MAP OPEN and CLOSE MAP dialogue Data DELIMITER

11 The Short Message Service
Not requiring the end-to-end establishment of a traffic path Asymmetric: Mobile Originating Short Message trasmission is considered as a different service from Mobile Terminating Short Message trasmission Ultimate destination (identified by some field in the message) is relevant only for the user and the SMSC, not for the GSM infrastructure 10 novembre 2018 PISATEL

12 MAP Services for SMS Provision of routing information
Forwarding of Mobile Originating and Mobile Terminating SMS message Delivery status reporting Alert service centre Miscellaneous information services 10 novembre 2018 PISATEL

13 MAP Primitives for SMS FROM MSC TO VLR (B): MAP_SEND_INFO_FOR_MO_SM MAP_SEND_INFO_FOR_MT_SM FROM SMSgwy TO HLR (C): MAP_SEND_ROUTING_INFO_SM MAP_REPORT_SM_DELIVERY_STATUS FROM HLR TO SMSgwy (C): MAP_ALERT_SERVICE_CENTRE MAP_INFORM_SERVICE_CENTRE FROM MSC TO HLR (D, via VLR): MAP_READY_FOR_SM FROM MSC TO SMSgwy (E): MAP_MO_FORWARD_SM FROM SMSgwy TO MSC (E): MAP_MT_FORWARD_SM D VLR HLR B C E SMSgwy MSC SMSC 10 novembre 2018 PISATEL

14 Protocols in the Short Message Service

18 by providing a new level of abstraction
JAIN Integrated Network APIs for the Java platform The objective of the JAIN initiative is to create an open value chain from 3rd-party service providers, facility-based service providers, telecom providers, and network equipment providers to telecom, consumer and computer equipment manufactures The JAIN initiative wants to integrate: wireline (PSTN), wireless (PLMN) and packet based (IP and ATM) networks by providing a new level of abstraction 10 novembre 2018 PISATEL

19 The JAIN initiative brings:
Business Drivers and Industry Goals The JAIN initiative takes the telecommunications/Internet market from many proprietary closed systems to a single open environment able to host a large variety of services making next generation telecom application development faster, simpler and less expensive The JAIN initiative brings: Portability: Write Once Run Anywhere Network Convergence: Any network !!! Secure Network Access 10 novembre 2018 PISATEL

20 The JAIN initiative is divided in two areas of development
The Protocol API Specification specify interfaces to wireline, wireless and IP signaling prtocols The Application API Specifications address the APIs required for service creation within a JAVA framework spanning across all protocols covered by the Protocol API Specification 10 novembre 2018 PISATEL

23 JAIN: JCC & JCT Supported services:
JAIN Call Control and JAIN Call Transaction are API for creating, monitoring, controlling, manipulating and tearing down communications sessions in a converged PSTN, PLMN and packed-switched environment. JCC allows to develop applications rapidly and efficiently that can execute on any platform Supported services: First and Third-party originated and terminated calls Voice virtual private networks (VPN) Toll-free number translation Voice-activated dialing Click-to-dial Meet-me conference 10 novembre 2018 PISATEL
