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

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

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

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
