Method and System of Interaction Between Entities on a Communication Network

摘要

A method and system of interaction between a requesting entity and a responding entity on a communication network based on the session initiation protocol (SIP). A machine-readable service description includes specifications of interaction between the requesting entity invoking a service at the responding entity and the responding entity offering the service. The specifications include at least a set of rules including abstract input/output message formats and SIP protocol binding rules so that the requesting entity may invoke the service to a SIP uniform resource identifier by means of SIP invocation message patterned according to the service description and it may interpret the response provided by the responding entity according to the service description.
