US 6,285,877 B1 · Cellular call processor having concurrent instances of call models to support mixed media communication connections

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.

Dependent claims

A cellular communication system for establishing a multi-media communication connection, having a plurality of media components, for a selected mobile subscriber station to implement multi-media communications with another subscriber station, comprising:

means for initiating a first communication connection, serving a one of said plurality of media components, from said selected mobile subscriber station to a base station;
means for processing said first communication connection by activating a first instance of a call model in said cellular communication system;
means for assigning a reference ID to said first communication connection;
means for initiating a second communication connection serving a second of said plurality of media components, for said selected mobile subscriber station to said base station, using said reference ID to identify said first communication connection;
means for processing said second communication connection by activating a second instance of a call model in said cellular communication system;
and
means for executing said first and said instances of said call models substantially independent of each other to establish said first and said second simultaneous communication connections.
