Abstract:
The present invention relates to a system that limits resources (e.g. reduces energy consumption and/or peak-to average power ratio) of a wireless communication device by limiting communication resources for the communication device from a network function of the cellular core network.
Abstract:
A system, method and protocol for guiding a user to establish an optimal wireless link. The method provides a first device (550) to communicate with a second device (500) in a wireless network, the method including: receiving, by the first device (550), location information of at least one antenna (510, 520) in the second device (500); providing, by the first device (550), an audio, visual, or audiovisual representation of the location of the at least one antenna (510, 520) in the second device (500).
Abstract:
A docking system comprises at least one host (100), multiple peripherals (110,111,112) and a head wearable device (120). The host is arranged for wireless docking with the head wearable device as a dockee. The head wearable device has a camera (123) for capturing an image of the peripherals in an operating environment, and a dockee processor (122) arranged for detecting, via the head wearable device, a focus position in the operating environment based on a viewing direction of a wearer, processing the image for identifying the peripherals, selecting a peripheral out of the peripherals in the image using the focus position, determining a selected host by determining the host that provides access to the selected peripheral, and docking to the selected host and accessing the selected peripheral. The host has a host processor (101) arranged for receiving a selection message indicative of the selected peripheral, docking the head wearable device as the dockee, and providing access to the selected peripheral.
Abstract:
A host device (200) for wireless communication with multiple dockee devices (220,221,230) is coupled to peripherals (210,211) for rendering audio or video (AV) data. The host has a docking processor for docking dockee devices for providing access to the peripherals. The dockee device has a dockee processor arranged for docking, as a dockee device, with the host device for getting access to the peripherals. The docking processor is arranged for docking at least one primary dockee device (230) and at least one secondary dockee device (220,221). Thereby, to the primary dockee device, control is provided over the peripherals for determining the AV data to be rendered. To the secondary dockee device is transferred the AV data to be rendered via the peripherals. For example a primary dockee device, presenter P, is enabled to control and determine the AV contents that are rendered, whereas secondary devices, attendees A, are enabled to monitor the AV data.
Abstract:
A host (100) provides a service to a dockee (120) via wireless docking. The host has a host wireless communication unit (102) and a near field receiver (103). When the user places the dockee near the host within a near field communication (153) distance, a near field transmitter (123) transmits a service search signal comprising a dockee identifier and a dockee service list for indicating services which are relevant to the dockee. The host determines a matching service set of services that are available at the host, and transmits, via the host communication unit, a service available signal comprising the dockee identifier and the matching service set via the host communication unit. The dockee processor determines whether the received dockee identifier corresponds to the dockee identifier and any of the matching services is actually required by the dockee, and if so, initiates the wireless docking with the host.
Abstract:
System for wireless communication comprises a group of wireless devices (110,120,130,140) that include at least one wireless host device (100) securely connected based on first secret data (240) shared by the group. A second secure connection is set-up between a portable wireless device (200) and a wireless host device based on second secret data (250). At least one of the wireless devices is instructed to apply a third secret data for setting up a direct wireless secure connection with the portable wireless device (200). Also the portable wireless device is instructed via the second secure connection to apply the third secret data for setting up the direct secure connections with the wireless devices based on the third secret data. Finally a respective direct wireless secure connection is set-up between the second device and a respective wireless device based on the third secret data. Advantageously latency is reduced in a secure wireless docking system.
Abstract:
A non-SI device (120) is arranged for wireless communication (130) and cooperates with an SI device (110) having access to a subscriber identity. The non-SI device has a transceiver (121) to communicate in a local network and a processor (122) to establish an association with the SI. A non-SI public key is provided to the SI device via a first communication channel. A verification code is shared with the SI device via a second communication channel. The channels are different and include an out-of-band channel (140). Proof of possession of a non-SI private key is provided to the SI device via the first or the second communication channel. From the SI device, security data is received that is related to the SI and is computed using the non-SI public key. The security data reliably enables the non-SI device to access the core network via the local network and a gateway between the local network and the core network.
Abstract:
A wireless device (S) includes a radio (R) for communicating via a wireless communication protocol which employs messages constructed as layer 2 MAC frames each including a layer 2 MAC header and a payload. The wireless device is configured to operate in (i) a first mode in which the wireless device transmits messages (N0, ..., Nn) via the radio each including an IPv6 packet header and an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame, and (ii) a second mode in which the wireless device transmits messages (M0, ... , Mn) via the radio each including an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame without including the IPv6 header. A relay device (T) comprises a radio for communicating via the wireless communication protocol which employs messages constructed as layer 2 MAC frames each including a layer 2 MAC header and a payload. In one power-saving aspect, the relay device is configured to perform a header insertion service (I) in which the relay device receives messages (M0, ..., Mn) via its radio from the wireless device (S), each including an upper layer protocol data unit encapsulated within the payload of a layer 2 MAC frame without including the IPv6 header. The header insertion service inserts header information (A') into the messages (M0, ..., Mn) received from the wireless device (S) and retransmits the messages with complete headers as messages (M0 ', ..., Mn '). In another power-saving aspect, the relay device additionally or alternatively applies an acknowledgement detection criterion to filter out acknowledgements received from the server, and forwards the filtered out acknowledgements to the wireless device (S) via the radio at a reduced rate.
