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

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

The interfaces

• Each entity communicate with each other through
  the appropriate interface

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

Services of the MAP protocol

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

9
Common services of MAP

• OPEN and CLOSE MAP dialogue
• Data DELIMITER
• User ABORT
• Provider ABORT
• Provider NOTICE

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

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

13
MAP Primitives for SMS

• FROM MSC TO VLR (B) MAP_SEND_INFO_FOR_MO_SM

JAIN Integrated Network APIs for the Java
platformThe 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
19
Business Drivers and Industry GoalsThe 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

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

JAIN JCC JCT
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
