  • Publication number: 20180041897
    Abstract: Some embodiments of the present invention relate to an apparatus, a method, and a computer program product related to coexistence of two network operators, for example a local operator and an incumbent operator. In certain embodiments, a method may include monitoring if network information from a server part of an application is received by a client part of the application. The client part is connected to the server part via a first network that uses a radio access technology. The network information is related to a second network that uses the radio access technology, the second network being different from the first network. The method also includes controlling a cellular radio layer such that it interworks with the second network based on the received network and authentication information.

  • Patent number: 9781085
    Abstract: A method, apparatus and computer program product are disclosed for establishing secure off-network communications between first and second Secure Cellular Devices that each have a cellular identity. The second Secure Cellular Device may assume the role of Remote Device for interaction with the NAF keyserver and may obtain a local key. The first Secure Cellular Device may derive the local key and the two devices may conduct secure communications using the shared local key. The two Secure Cellular Devices may alternate the roles of Secure Host and Remote Device, each twice obtaining or deriving a shared local key such that there are two such keys. The devices may employ one key for secure communication in one direction and the other for communication in the other direction. Alternatively, the devices may derive a unique shared key as a function of the two shared keys.

  • Publication number: 20170272948
    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.

  • Patent number: 9763080
    Abstract: A method, apparatus and computer program product are provided to selectively establish communications with one or more of a plurality of mobile terminals in accordance with a predefined criteria, such as a predefined schedule. In the context of a method, a mobile terminal maintains at least a first subscriber identity module (SIM) and a second SIM is mapped to different subscriber identification numbers. In this regard, the second SIM is mapped to the same subscriber identification number as the SIM of at least one other mobile terminal. The method may also activate the second SIM in accordance with a predefined criteria and may then subsequently deactivate the second SIM. For example, the second SIM may be activated and subsequently deactivated in accordance with a predefined schedule, such as a shift schedule, that identifies one or more time periods in which the second SIM is to be activated.
