METHOD OF CAPABILITY NEGOTIATION OF APPLICATION PROGRAM IN MULTIPOINT DATA CONFERENCE CONTROL MODULE

摘要

PURPOSE: The method for negotiating the capability of the application program of module controlling multi-point data conference is provided to improve the communication performance by enabling all the system, joining to the conference, to communicate each other in the best status. CONSTITUTION: The method comprises the following steps. When the new application capability is registered(601), it is checked if the Capability_ID of the new registered application capability exists in the Capability_List of the capability roster(602). If no, the number of entities sets to one(603). The new Capability_ID is appended to the capability roster(604). If the Capability_List exists, one is added to the number of entities(605) and it is checked if the type of the application capability class is Maximum_Class(606). In case of Maximum_Class, it is checked if the inputted capability value is bigger than the application capability value of the capability roster(607). If yes, the inputted capability value is set as the new capability negotiation value(608). Otherwise, it is checked if the inputted capability value is smaller than the application capability value of the capability roster(607). In case of small, the inputted capability value is set as the new capability negotiation value(611). If the capability class is the logical class, the process does nothing.
