Interoperability means that how different telecommunication devices of different generation communicate with each other. This topic is gaining importance because we have to make the devices backward compatible so that old devices can work together with new evolved system and techniques. It is the main problem of today’s telecommunication industry to establish a link between heterogeneous networks.

3. Interoperability
• Interoperability is the ability of a system or device to work
with other systems or devices without any special effort from
user side.
• It is the main problem of today’s telecommunication industry
to establish a link between heterogeneous networks.

6. Need of interoperability
• Interoperability is essential in order to achieve worldwide end
to end connectivity. It enables us to call anybody in the world
using old PSTN, GSM phone or Computer using Internet

8. Customer view of Interoperability
• It is defined as the ability of networks to send and receive data
between interconnected networks keeping the level of quality
as expected by the customer.

9. Interoperability in Networks
• Interoperability in network is defined as the ability of two or
more networks, systems, applications to exchange data in
between them and use these information.

10. How to achieve interoperability
• Interoperability can be achieved either by having to networks
conform to a common protocol ,or by defining a standard
interface to which all networks need to agree.so there is need
of standards to achieve interoperability .

12. Advantages of interoperability
• User benefit
• Network operator
• The manufacturer benefits
• Public authority’s benefits

13. Levels of interoperability
• Physical Level
• Network Level
• Application Level
• Managements Aspects

14. Fixed and Mobile Network Integration
• Network can be used in their current form without modification of
network nodes only minor changes to the protocol.
• The integration can be done by reconfiguration of network systems into
a Generic Radio access network, a backbone transport network and a
service network. For example the integration of GSM,UMTS,PSTN and
ISDN

15. Fixed and Mobile Network Integration
• Major Concerns
• Guarantee of Security in Internetworking
• Impact of mobility on internet(Switching capabilities and control functions)
• Network Interfaces according to provided Standards
