Abstract: A first node (10) and a second node (12) are configured for the transfer of data between them. The second node (12) is configured to determine an extent to which the second node (12) will be available for a prospective transfer (16) of data (e.g., application data) to or from the second node (12). The second node (12) is configured to transmit to the first node (10) control signaling (20) (e.g., application-layer control signaling (20)) that indicates the determined extent. The first node (10) is configured to determine, based on the control signaling (20), whether and/or when to proceed with the prospective transfer (16) of data.

Abstract: 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.

Abstract: A method performed by an Operation and Support System (OSS) node for handling communication between a wireless device and a communication network node in a communication network, which communication network comprises a first radio access node associated with a first gateway and a second radio access node associated with a second gateway. The OSS node determines to initiate a change of an Internet Protocol (IP) address for the wireless device. The OSS node further identifies a session of packets for the wireless device, which session is run over a protocol that supports session continuity even though source or destination IP addresses change in the packets. Furthermore, the OSS node triggers the change of the IP address associated with the first gateway for the wireless device, of packets of the session, to a changed IP address associated with the second gateway.

Abstract: Embodiments include methods for handling data units in a communication protocol layer (e.g., PDCP) of a network node for a wireless communications network. Such methods include receiving, from a lower protocol layer, one or more first data units with corresponding first sequence numbers. Such methods include, upon expiration of a first timer, forwarding the first data units to a higher protocol layer without receiving one or more second data units, from the lower protocol layer, with corresponding second sequence numbers that are lower than the first sequence numbers. Such methods include forwarding, to the higher protocol layer, any of the second data units that were received from the lower protocol layer during a second time period after expiration of the first timer. Other embodiments include network nodes (e.g., base stations, UEs) configured to perform such methods, as well as computer-readable media containing instructions that embody such methods.

The method performed by the media user agent in a node in a communication network for providing media from a media server to a media user client in a user terminal comprises receiving a request for media from the media user client, the request for media comprising information about the requested media; and transmitting a request of the media to a media server, the request comprising the information about the requested media. The method further comprises receiving an MPD from the media server; and autonomously requesting segment(s) of the media from the media server based on the MPD.

Abstract: A network node 606,608 and a method for Packet Data Convergence Protocol (PDCP) reordering. The network node is operating in a wireless communications network 600. The network node buffers in order one or more first data units received out of order by a PDCP layer, wherein the one or more first data units are received from a lower layer during a first time period, and wherein the lower layer is a layer below the PDCP layer. When the first time period has expired, the network node forwards the one or more buffered first data units in order to an upper layer and starts a second time period. Further, the network node forwards, to the upper layer and in any order, one or more second data units received from the lower layer during the second time period.
