Abstract: A technique for detecting an encoder functionality issue in a media distribution system is presented. In the media distribution system consecutive media segments generated by an encoder are transmitted to a media client, and media descriptions describe expected availability times of media segments for the media client. A method implementation of the technique comprises the step of monitoring an availability time of a media segment compared to an expected availability time of the media segment, wherein the expected availability time is described by, or derived from, a media description. The method further comprises determining whether a deviation of the monitored availability time of the media segment from the expected availability time of the media segment is present, and detecting the encoder functionality issue based on a result of the determination. The encoder functionality issue may comprise one or more of an encoder restart, an encoder malfunction and an encoder time drift.

Abstract: A software-defined media platform having one or more media processing units that may be dynamically instantiated, interconnected and configured according to changes in demand, resource availability, and other parameters affecting system performance relative to demand. In one example media processing method, a source media stream may be received via multicast or unicast. The source media stream may be processed into one or more levels of work product segments having different media characteristics by a plurality of transcoding processing units, as needed. One or more levels of work product segments, or the source media stream, may be packaged (e.g., including resegmenting) into final work product segments having select media characteristics, which may be uploaded to a cloud storage unit for delivery to end users.

Abstract: According to certain embodiments, a network node comprises processing circuitry and computer executable program code. When executed by the processing circuitry, the computer executable program causes the network node to perform actions. The actions comprise obtaining grouping information that associates a plurality of users with a group and determining, based on the grouping information, content to be cached near the users that are associated with the group. The actions facilitate caching the content in one or more caches. The one or more caches are selected from a plurality of caches based at least in part on proximity to the users to associated with the group.

Abstract: A first node receives data packets of a flow and forwards the data packets of the flow to a second node. The first node takes a first decision whether to perform inspection of a payload section of at least one data packet of the flow at the first node and indicate a result of the first decision to the second node. The second node receives the data packets of the flow from the first node. On the basis of the result of the first decision indicated by the first node, the second node takes a second decision whether to perform inspection of a payload section of at least one data packet of the flow at the second node.

Abstract: Method and apparatus for conveying precoding information in a control message (M) from a first node (400) to a second node (402), with information on properties of an associated wireless data transmission (D) between the first and second nodes employing spatial multiplexing and precoding for the data transmission. The first node determines precoding parameters (P) for signal transmission to the receiving node, optionally based on feedback reports (F) from the receiving node. The first node encodes control information bits in precoding information fields of the control message by means of values in TBS fields of the control message, such that the TBS field values determine the interpretation of the bits in the precoding information field(s). The control message (M) is then sent to the second node.

Abstract: There is provided mechanisms for robust wireless radio transmission. A method is performed by a network node. The method comprises acquiring data to be transmitted on a wireless radio link. The method comprises separating the data into a radio access technology (RAT) payload part and a management data part. The method comprises acquiring channel condition values for the wireless radio link. The method comprises dynamically allocating resources between the RAT payload part and the management data part according to the channel condition values. The method comprises transmitting the data over the wireless radio link using said allocated resources.

Abstract: Method and gateway unit for registering a user terminal (34) of a multimedia subscriber being a subscriber of a circuit switched network (32), in an IP multimedia system (IMS) network (31). Registration in the IMS network (31) of a first contact address associated with a circuit switched communication capability of the user terminal (34) for regular communication purposes is used, as well as registration in the IMS network (31) of a second contact address associated with a circuit switched communication capability of the user terminal (34) for messaging purposes.

Abstract: The proposed layer solution defines two or more layers of relay nodes to convey traffic data from a source node to a destination node. All of the nodes in a given layer were selected for that layer because they each satisfied a signal quality requirement specified for that layer, where all relay nodes defined in one layer simultaneously start transmitting in response to a received transmission. Due to the layered approach, the destination node may be configured to decode only the traffic data relayed by the relay nodes in the immediately preceding (final) layer while treating any remaining received signals as noise. As a result, only those access nodes most likely to significantly contribute to and improve the signal quality of traffic data received at the destination node are selected as relay nodes for a particular source-destination node pair.

Abstract: A mechanism for forming and using shortened Uniform Resource Locators or URLs for resources available within a Machine-to-Machine, M2M, network enables the use of a Domain Name Server based routing of M2M messages between entities within the M2M network domain without requiring the memory-intensive storage that would be required for indicating the full network topology associated with the actual resource locations.

Abstract: The present disclosure relates to a base station in a cellular communication network and methods of operation thereof. In one embodiment, a base station determines that the base station is transitioning to an unavailable state. The base station then notifies one or more radio network nodes with which the base station conducts base-station-to-node communication that the base station is unavailable. Thereafter, in one embodiment, the one or more radio network nodes cease communication attempts with the base station. In this manner, the radio network nodes can avoid spending additional resources on attempts to re-establish communication connections to base stations that tend to be offline more often (e.g., low-power base stations (LP-BSs)).
