Abstract: A method is provided for supplying data to represent the availability value of a plurality of resources that includes receiving a request for presentation of an availability value for a plurality of resources and determining at least two resources having representative values that can be received, two representative values are received each corresponding to a respective one of the two resources and supplying data to represent the calculated availability value. The method includes receiving two criticality coefficients corresponding to the two resources, and calculating the availability value from the two representative values and the two criticality coefficients.

Abstract: A method of supplying data to represent the availability value of a plurality of resources, the method comprising the steps consisting in receiving a request for presentation of an availability value for a plurality of resources, in determining at least two resources having representative values that can be received, receiving two representative values each corresponding to a respective one of said two resources, of supplying data to represent said calculated availability value, of receiving two criticality coefficients corresponding to said two resources, and of calculating said availability value from said two representative values and said two criticality coefficients. The invention is useful in particular in the field of telecommunications between users, and more particularly that of providing means to a system for extending the concept of the availability of a user of a mobile or fixed network.
