Abstract

The cellular call processor having concurrent instances of call models supports mixed media communication connections. The cellular call processor processes each of the media components of the mixed media communication connection in an independent, yet coordinated manner. Thus, each of the media components of the mixed media communication connection can be processed in an efficient media-specific manner and even directed to different destinations. The cellular call processor can implement this capability in a plurality of ways, one of which is to maintain the existing voice call model and create a new call model for each of the other call components in a media-specific manner. Alternatively, multiple instances of the same call model can be used, with each call component being served by a separate instance of the call processing code. Communications among the various instances of the call models occur only at the call setup and release and the call models can be implemented in the same physical network element or can be implemented in separate network elements that are customized for the type of call component being processed.
