Middleware is currently used in all the customized software systems in order to felicitate the applications to majorly work on their functionality not on to much of process, memory management, load analysis, counter, timers, DataBase [DB], fault detection & correction and other such constraints which are very important in building the network machine software's like what the people use in 3G and 4G networks. (i.e. in IMS, IP Multimedia Subsystems). The middleware of IMS will provide API's (Application Program Interfaces) which will be used by the applications to perform their set of functionality.
