  • Patent number: 10476926
    Abstract: A scheme for managing delivery of segmented media content in an ABR network, wherein bitrates of a manifest file may be selectively modified or removed based on a client device's video buffer characteristics. An ABR stream delivery server is operative to simulate the client device's video buffer in a streaming session and accordingly modify the manifest files to include metadata for media segments encoded at a particular single bitrate responsive to the buffer performance and other network conditions. Responsive to monitoring the video buffer characteristics of the media player during the streaming session, a selected single bitrate may be moved up or down to other bitrates of the manifest files.

  • Patent number: 10474505
    Abstract: Systems and methods of managing computational resources are provided. In one exemplary embodiment, a method by a controller (305, 407, 500, 600, 700, 1101) for managing computational resources may include dynamically distributing (801) computational resource shares among sequential services that are mapped to one or more processors (303, 403). Further, each sequential service corresponds to an execution step of a remote application (307, 409). Also, a service chain (313-315, 413-415) comprises at least one sequential service. The dynamical distribution is based on estimated and predetermined tail latencies and average execution times of each sequential service in the service chain as well as the service chain such that the latencies are met. In addition, the one or more service chains are executed contemporaneously.

  • Publication number: 20190342797
    Abstract: A method and a migration managing module for managing a migration of a service. The migration managing module determines a point in time relating to completion of the migration of the service based on resource requirements related to the service. For each radio network node a respective impact on a quality of the service is estimated. Moreover, the migration managing module selects from among servers at least one respective target server for which the respective server location measure of said at least one respective target server matches the respective radio network node location measure of said each radio network node, thereby obtaining a set of target servers comprising said at least one respective target server for said each radio network node. For each target server, a respective cost of the migration based on the resource requirements related to the service is determined. A respective tendency as a function of said each probability value, the respective cost and the respective impact is determined.

    Abstract: The embodiments herein relate to a method performed by a testing device for enabling testing of a communication node. The testing device measures a test parameter associated with RF characteristics of the communication node when it is located at a test location during a first condition. The communication node is configured with a node setting during the measurement in the first condition. The testing device measures the test parameter associated with the RF characteristics of the communication node when it is located at the test location during a second condition. The communication node is configured with the same node setting in the second condition as in the first condition. The testing device checks whether a result parameter associated with the test parameter measured during the first and second condition fulfills a requirement.

  • Patent number: 10468044
    Abstract: Vector Quantizer and method therein for vector quantization, e.g. in a transform audio codec. The method comprises comparing an input target vector with four centroids C0, C1, C0,flip and C1,flip, wherein centroid C0,flip is a flipped version of centroid C0 and centroid C1,flip is a flipped version of centroid C1, each centroid representing a respective class of codevectors. A starting point for a search related to the input target vector in the codebook is determined, based on the comparison. A search is performed in the codebook, starting at the determined starting point, and a codevector is identified to represent the input target vector. A number of input target vectors per block or time segment is variable. A search space is dynamically adjusted to the number of input target vectors. The codevectors are sorted according to a distortion measure reflecting the distance between each codevector and the centroids C0 and C1.

  • Patent number: 10470083
    Abstract: A network node determines a system load of the network node for the UE. When the UE is capable of receiving control information on EPDCCH, the system load is determined based on a first and a second system load metrics on a physical resource shared by PDSCH and EPDCCH, which first load metrics comprises a load due to EPDCCH and a load due to multiplexed PDSCH and which second load metrics comprises a load due to multiplexed EPDCCH and a load due to PDSCH. When the UE is not capable of receiving control information on EPDCCH, the system load is determined based on the first system load metrics on the physical resource shared by the PDSCH and EPDCCH and a third system load metrics on a physical resource for carrying PDCCH. The network node further determines whether or not to allocate resources to the UE based on the determined system load metrics.
