A user terminal emulation server maintains a database identifying network addresses, UI capabilities, and locations of I/O user devices. Communication sessions are established between first and second user terminal emulation applications and respective first and second I/O user devices proximately located to respective first and second users and which provide acceptable combined I/O user interfaces to the first and second users. When a direct path criterion is satisfied for creating a direct traffic flow, a traffic flow that was from the first I/O user devices to the first user terminal emulation applications is redirected to now be from the first I/O user device to the second I/O user device without passing through either of the first and second user terminal emulation applications.

Providing communication services using sets of I/O user devices

A user terminal emulation server is provided that provides operational functionality of a user terminal using a networked set of I/O user devices that are determined to be proximately located to a user and to have user interface capabilities that are combinable to provide the user with the ability to receive or initiate a communication service with another user terminal through a network entity. The operations for emulating a user terminal may alternatively be performed by an I/O user device that provides communication services (using other I/O user devices.

Providing communication services using sets of I/O devices

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

Transfer of data between nodes

The disclosure provides methods, apparatus and machine-readable mediums relating to buffer status reporting in wireless communication systems. One aspect provides a method performed by a user equipment. The user equipment is configurable to communicate with a radio access node via a plurality of communication protocols, and to communicate with a network node via at least one congestion-controlled application transport protocol. The method comprises: generating a buffer status report comprising an indication of a first amount of data available for transmission from the user equipment, the first amount of data including at least data stored in a buffer for data conforming to the congestion-controlled application transport protocol; and transmitting the buffer status report to the radio access node.

Buffer status reporting in wireless communication systems

A method performed by a first wireless device () is provided. The method comprises transmitting () a radio signal towards the at least one second wireless device indicating that the first wireless device is, or that the at least one second wireless device has an option to be, responsible for beamforming of transmissions over the direct D2D communication link. The method also comprises receiving () information from the at least one second wireless device indicating which of the first wireless device or the at least one second wireless device is to be responsible for beamforming of transmissions over the direct D2D communication link. Further, the method comprises configuring (), based on the received information, which of the first wireless device or the at least one second wireless device is to be responsible for beamforming of transmissions over the direct D2D communication link.

A method is provided for generating a media descriptor file for first streaming media content. The method is performed in a file generator and comprises the steps: obtaining metadata for the first streaming media content, the metadata comprising a reference to a media descriptor file for second streaming media content, the second streaming media content being separate from the first streaming media content; and generating the media descriptor file comprising the metadata.

Media descriptor file comprising a reference to other streaming media content

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.

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.

Network node and methods therein for packet data convergence protocol (PDCP) reordering

A user terminal emulation server is provided that provides operational functionality of a user terminal using a networked set of I/O user devices that are determined to be proximately located to a user and to have user interface capabilities that are combinable to provide the user with the ability to receive or initiate a communication service with another user terminal through a network entity. The operations for emulating a user terminal may alternatively be performed by an I/O user device that provides communication services using other I/O user devices.

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.

A network nodeand a method for Packet Data Convergence Protocol (PDCP) reordering. The network node is operating in a wireless communications network. 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.
