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.

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

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.

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.

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 .

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

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

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

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
