A radio access network intelligent controller (RIC) can comprise a physical resource block (PRB) scheduler that can facilitate the streaming of videos. When a user equipment (UE) requests a video, the PRB scheduler can take into account channel quality data associated with the connection between the UE and a distributed unit of a base station. The PRB scheduler can also receive video stream rate information from a video server. Based on the video stream rate information and the channel quality data, the PRB scheduler can make a decision regarding what types of videos to facilitate streaming to the UE.

The present disclosure provides a method for transmitting resources. The method includes: determining the target bitrate of a target moment; in response to the target bitrate being inconsistent with the current bitrate, acquiring target address information of a multimedia resource having said target bitrate; and sending to a server a frame acquisition request carrying the target address information, the frame acquisition request being used to instruct the server to return a media frame of said multimedia resource at the target bit rate.

A system and method for identifying a viable channel within an allocated downstream spectrum and establishing communication via a modem thereon. The disclosed technology provides for the broadband analysis of some or all of the available downstream spectrum to obtain a mapping of available channels and directing the modem to establish downstream communication upon at least one of these channels. The system includes an interface via which a user can specify parameters governing the analysis of the available downstream spectrum and the identification of a viable downstream channel.

This application relates to the field of communications technologies, and in particular, to an auxiliary-link-based call compensation system and apparatus, and chip. The system includes: a first terminal, a second terminal, and a core network device. The first terminal and the second terminal establish a primary link in response to a dialing operation entered by a user. The first terminal and the second terminal establish at least one auxiliary link in response to an auxiliary link establishment condition. The first terminal transmits call data packets with the second terminal by using the primary link and the at least one auxiliary link. The first terminal and/or the second terminal performs post-processing and playing on the call data packets received by using the primary link and the at least one auxiliary link.

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for controlling a congestion window (CWND) value of a communication session of a CDN. In particular, a content server may analyze a request to determine or receive an indication of the type of content being requested. The content server may then set the initial CWND based on the type of content being requested. For example, the content server may set a relatively high CWND value for requested content that is not particularly large, such as image files or text, so that the data of the content is received at the client device quickly. For larger files or files that a have a determined smaller urgency, the initial CWND may be set at a lower value to ensure that providing the data of the content does not congest the link between the devices.

Devices, systems, methods and computer-readable media are provided for data communication to and from a vehicle. A device is provided that includes memory storing processor-executable instructions; and at least one processor in communication with the memory that executes the stored instructions to: receive, from at least one user on the vehicle, at least one request for data communication; identify a plurality of communication links available at a current location of the moving vehicle; form an adaptive bonded communication link using the plurality of communication links to aggregate throughput across the plurality of communication links for the requested data communication, wherein the adaptive bonded communication link is configured to adapt to data communication requirements for the requested data communication and to data communication characteristics of the plurality of communication links as the vehicle moves. Corresponding methods, computer system products, uses, and computer-readable media are also provided.

Methods, systems, and apparatuses for improved content scoring and delivery are described. A quality score for delivered content may be determined based on one or more output metrics. A first quality score may be provided to a content distribution network. The content distribution network may instruct the user device, or the user device may determine without receiving such an instruction, of methods/processes by which it may improve the one or more output metrics associated with output of the delivered content by adjusting one or more output parameters. The first quality score may also be used by the content distribution network to determine methods/processes by which network-related parameters and constraints may be managed in order to improve the quality of delivered content.

A method provides for delivering video content from a server to a plurality of media devices is disclosed that distributes accurately excess bandwidth. The method includes: determining, by the server, the bandwidth to allocate to each of the plurality of media devices using a hypertext transfer protocol-based live streaming client model or a need parameter vector and/or measured bandwidth limitations associated with each of the plurality of media devices and providing the allocated bandwidth to each of the plurality of media devices, wherein the video content is transmitted in a plurality of segments from the server, and wherein each segment is transmitted at a bitrate that may vary from segment to segment.

Correlated quality-of-experience (QoE) and latency measures are generated at a plurality of monitoring points along a multimedia delivery chain including multiple video operations. At each of the plurality of monitoring points, an absolute QoE measure defined on a human perceptual quality scale for media content is computed, and one or more of content extraction or feature extraction on the media content are performed. To a common middleware from each of the plurality of monitoring points, the respective QoE measure and results of the one or more of content extraction or feature extraction are transmitted. Computing and updating an absolute QoE measure for each of the plurality of monitoring points is performed. Computing and updating latencies between multiple monitoring points at the middleware using the results from each of the plurality of monitoring points is also performed.

Disclosed is a method of managing congestion by a Policy Control and Charging Rules Function (PCRF). The method includes receiving at least one piece of video flow related information; receiving, from an evolved Node B (eNB), congestion state information for the eNB and at least one User Equipment (UE); determining a data transmission rate of at least one video flow on the basis of the received congestion state information and the received video flow related information; and adjusting the data transmission rate of the at least one video flow on the basis of the determined data transmission rate.
