Abstract: The invention relates to a technique of co-operation between a plurality of client entities communicating among themselves by way of at least one instantaneous-communication channel established between the client entities and said plurality. A first client entity of said plurality dispatches an executable application to at least one second client entity of said plurality by way of said at least one instantaneous-communication channel. This application is then executed by the first client entity in co-operation with an execution of said application on the second client entity.

Abstract: A method for processing data associated with a caller party upon setup of an incoming communication is proposed. The method includes: obtaining, from received signaling data associated with the communication, caller party identification data; transmitting a request for qualification of the nature of the caller party including the caller party identification data; receiving, in response to the request, qualification information on the nature of the caller party including respective likelihood indicators for each of one or more categories to which the caller party corresponds; and reporting incoming communication acceptability information that includes the likelihood indicators for each of the one or more categories through a user interface.

Abstract: The invention relates to a technique of co-operation between a plurality of client entities (10, 11, 12) communicating among themselves by way of at least one instantaneous-communication channel established between the client entities and said plurality. A first client entity of said plurality dispatches an executable application to at least one second client entity of said plurality by way of said at least one instantaneous-communication channel. This application is then executed by the first client entity in co-operation with an execution of said application on the second client entity.
