EFFICIENT ALLOCATION AND USAGE OF COMMUNICATION CHANNELS FOR TEXT STREAMS

摘要

A communication system capable of allocating resources to provide text services to IP telephone users upon receiving requests for text services during a telephone call or during the establishment of the telephone call. The system uses available resources for text services efficiently in that it allocates the resources upon receiving a request for text services and de-allocates the resources upon termination of the telephone call or upon receiving a request for termination of text services during the telephone call. A party to the telephone call can make a request for text services or make a request to terminate text services during the telephone call by activating a button on its IP phone.
