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

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

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

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

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

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

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
