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 .

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
