The invention relates to a system comprising a mobile device (), a device () for transmitting information, a device () hosting a device registry () and a wireless device (). The mobile device () comprises a receiver, a transmitter, storage means and a processor. The processor is configured to use the receiver to determine that a wireless device () has newly connected to the mobile device (), to store or update a profile corresponding to the wireless device () on the storage means, to use the transmitter to transmit first information to at least one device registry (), the first information comprising an identifier of the wireless device (), to use the receiver to determine that a status of the wireless device () has changed to a new status, to update or remove the profile stored on the storage means if the status of the wireless device () has changed co to the new status, and to use the transmitter to transmit second information to the at least one device registry () if the status of the new wireless device () has changed to the new status, the second information comprising the identifier of the wireless device () and the new status. The invention further relates to a device () for transmitting information, the methods performed by these devices and one or more computer program products enabling a computer system to perform these methods.

System and methods for registering wireless devices and transmitting information

The invention relates to a method for controlling access for a user equipment to at least one local device via an intermediary system that is configured to connect to a local network and to a public network. The user equipment is connected to the public network and the at least one local device is connected to the local network. The method comprises a number of steps in the intermediary system. One of these steps is storing one or more location conditions for access for the user equipment to the at least one local device. Another step is receiving first location information of the user equipment over the public network, the first location information indicating a location of the user equipment. Yet another step is controlling access for the user equipment to the at least one local device by verifying whether the first location information satisfies the one or more location conditions. The invention further relates to the intermediary system used in the method.

Method and system for controlling access for a user equipment to a local device

Methods and systems are disclosed enabling establishment of a direct connection between a first device connected to a first network and a second device connected to a second network upon finding a permission response from a third device connected to a third network. Establishment of the direct connection is controlled by a second network node associated with the second network. A connection request is received from the first device at at least one of the second network node or a third network node associated with the third network and a permission indication is found indicating that a connection with the second device is subject to permission from the third device. A permission response may be found from the third device to permit the connection request for enabling establishment of the direct connection. Establishing of the direct connection is enabled between the first device and the second device in response to finding the permission response.

Method for enabling establishment of a direct connection

One aspect of the disclosure relates to a method in a user equipment for instructing establishment of a connection between a first local device and a second local device, the user equipment being connected to a public network, wherein an intermediary system is configured to connect to a first local network, to a second local network and to the public network. A virtual view is generated and, upon receiving a selection of a representation in the view, connectivity information is obtained regarding the communication path between the first local device and the second local device. An ability for user to instruct establishment of communication path in dependence of the connectivity information.

Establishment of a connection between two local devices connected to different networks

Methods and systems enabling the end users of cellular devices to set up infrastructure-based D2D connections with other devices from within the over-the-top (OTT) applications running on their devices are disclosed. The methods are based on dynamically reconfiguring respective network-level firewalls protecting different end user devices.

Infrastructure-based D2D connection setup using OTT services

The invention enables a device to discover one or more other devices within range for a device-to-device mode of communication. This proximity discovery may trigger a target device, e.g. to start listening to signals from a source device or perform any other action based on the proximity discovery like e.g. charging at a toll gate. A source device that wants to be discovered broadcasts a message including an identifier or a representation of the identifier. This identifier may be an identifier of the target device to be contacted or of the source device or a derivation thereof or a common security association used by a set of peers. The target device compares the broadcast identifier with a known identifier to establish proximity discovery.

Proximity discovery, authentication and link establishment between mobile devices in 3GPP LTE

A method is disclosed for establishing a device-to-device communication session between mobile devices which are mutually connectable via a D2D communication channel (DDC) and individually connectable to a mobile network (MN), including preloading an initiation key on each of the mobile devices, the initiation key being associated with a validity period; and on each of the mobile devices: verifying a validity of the initiation key based on a current time; if the initiation key is deemed valid, generating a session key using the initiation key by using the initiation key in performing a key agreement procedure between the mobile devices over the D2D communication channel (DDC), the key agreement procedure resulting in the session key if the initiation key used by each of the mobile devices matches; and establishing the D2D communication session over the D2D communication channel (DDC) based on the session key.
