摘要： There is provided mechanisms for triggering mobility measurements. A method is performed by a network node. The method comprises obtaining information about backhaul link quality of a wireless backhaul link of the network node. The method comprises, as a result thereof, sending, to at least a subset of all UEs served by the network node in a cell, an indication for the subset of UEs to perform mobility measurements. The method comprises receiving mobility measurement reports from the subset of UEs. The method comprises determining a handover action for the subset of UEs based at least on the backhaul link quality and on the mobility measurement reports.

摘要： A user terminal emulation server maintains a database identifying network addresses, UI capabilities, and communication protocols of I/O user devices. Communication sessions are established between a user terminal emulation application and a network entity and I/O user devices proximately located to a user and provide a combined I/O user interface. Delay profiles are determined between the application and the I/O user devices. A downlink flow from the network entity is split into a plurality of downlink flow components assigned to the I/O user devices. For each of the downlink flow components, the server formats the component for transmission to the assigned I/O user device, initiates transmission of the formatted downlink flow component to the assigned I/O user device, and controls timing for when the formatted downlink flow component is transmitted to the assigned I/O user device based on the delay profile associated with the assigned I/O user device.

摘要： According to an aspect, a wireless device receives (302) a preview digital image from a computer server and applies object recognition processing (304) to the preview digital image, to determine (306) whether the preview digital image contains a representation of a known object of interest. Responsive to a positive determination, the wireless device transmits (308) an indication of the positive determination. The computer server sends, in response to the transmitted indication, an enhanced digital image corresponding to the preview digital image, or additional image data, which is received (310) by the wireless device. In the latter case, the wireless device forms an enhanced version of the preview digital image using the additional image data. The wireless device at least temporarily stores (312) the enhanced image or image version, e.g., for rendering on a display screen of the device.

摘要： A distributed microphones signal server includes a network interface circuit that communicates with mobile terminals and a plurality of microphones that are geographically distributed. The server receives an audio request message containing a location of the mobile terminal, and selects a microphone from among the plurality of microphones responsive to the location of the mobile terminal. The server obtains an audio stream from the selected microphone, and communicates the audio stream to the mobile terminal. Related methods by a distributed microphones signal server are disclosed. Related computer program products and methods by a mobile terminal are disclosed.

摘要： The application discloses methods and corresponding systems and network devices and/or nodes for enabling user equipment belonging to a home network to access data communication services in a visited network of a wireless communication system. By way of example, there is provided a method that comprises the step of obtaining at least one cryptographic token originating from a network node of the home network of the user equipment and cryptographically signed by a private key associated with the home network, wherein the at least one cryptographic token represents means for accessing data communication services via user data transport functions of the visited network. The method also comprises cryptographically signing the obtained and signed token by a private key associated with the user equipment to generate a double-signed token, and sending the double-signed token to a network node of the visited network, which validates the double-signed token for enabling the user equipment to access data communication services via the user data transport functions of the visited network.
