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

4. The SS7 Signaling protocol
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
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.

7. 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

8. 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. 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

14. JAIN for MAP The first version of the JAIN MAP API will include a subset of all capabilities of the MAP protocol
Functionalities to be supported:
Short Message Service (SMS)
User to service data transfer (Unstructured Supplementary Service Data)
Subscriber Information (Any Time Interrogation)
Location Service and Emergency Location Information Delivery
