A method is provided for allowing an exchange of context information within a group of users sharing one and the same identifier. The method includes transmitting information between at least one first terminal and a second terminal associated with a common identifier. The method includes a step of sending by the first terminal a notification of state intended at least for the second terminal and carrying an item of information relating to the context in which a user of the first terminal finds himself. The method allows members of a community of users, which is identified by a unique telephone number, to avail themselves of context information relating to the other members of the community at any moment, and in particular at the precise moment at which a setup request for establishing a communication is presented to them.
