  • Patent number: 10791456
    Abstract: A method, apparatus and computer program product are provided to selectively accept requests for communication that may be supported by different identification profiles with the selective acceptance being based upon a predefined criteria, such as the cost of the communications. In the context of a method, a request for communications is received from a network operator. The communications with the network operator are supported by a first of a plurality of identification profiles. The method also includes determining, relative to a predefined criteria, whether the communications should be supported by the first identification profile or by another identification profile configured to support communications with another network operator. In an instance in which the communications should be supported by another identification profile, the method causes the request for communications to be denied.

  • Patent number: 10425812
    Abstract: The invention relates to a method and devices for mutual communication between devices, and to computer programs enabling such communication. According to the invention, in a first device is controlled a transmitter module operable in a local radio communications network to transmit a sequence of radio signal pulses representing a predetermined code. In at least one second device a receiver module is scanning said local radio communications network to detect said predetermined code. A contact network of the user of said at least second device is accessed, and the predetermined code is checked in the second device against the user's contact network for a match stored in the network profiles for the contacts. Then a validation key is fetched, that relates to a matching contact found in said contact network, and a connection establishment request containing the validation key is sent over said local radio communications network from the second device to the first device.
