  • Publication number: 20220256306
    Abstract: The disclosure concerns a method for subscribing a mobile device to information on events from a geo-service hosted on a peripheral server for processing data in an MEC architecture network. The method includes the steps of: sending a registration message to a central server; sending a subscription message, to a type of event, to the peripheral server; receiving a message giving information on an event of the type, the registration message indicating the event type, and sending of the subscription message being subject to the prior reception of a notification message that an event of the type has occurred and that the corresponding information is suitable to be communicated by the peripheral server.

  • Publication number: 20220132449
    Abstract: A method corrects the time defined by an internal clock of an entity capable of receiving signals from a satellite positioning system and of communicating with at least one other entity. When the signals do not allow the satellite positioning of the entity, the method includes: receiving, by the entity, a message originating from the other entity, the message including a first piece of time data associated with the instant the message was transmitted; determining, by the entity, a second piece of time data associated with the instant the message was received by the entity; calculating a time difference between the second piece of time data and the first piece of time data; and then, when the time difference is negative, determining a time correction to be made to the internal clock of the entity.

  • Publication number: 20210377782
    Abstract: A method for reallocating a data processing peripheral server in an MEC architecture includes: a prior step of allocating a current peripheral server to process data for a mobile device, by a management unit, selecting a new peripheral server by the management unit, and notifying peripheral server reallocation to the current peripheral server by the management unit. The selecting is preceded by receiving, by the management unit, of a message dispatched by the mobile device and including a data item representative of a quality of service measured at the level of the mobile device.

  • Patent number: 11044186
    Abstract: Technologies for link capability estimation are disclosed. A compute device may determine a maximum radio bitrate for a certain connection, such as an LTE connection to a specific cell antenna. The compute device may also determine a maximum downlink bitrate for that connection, and store both the maximum radio bitrate and the maximum downlink bitrate in a database on the compute device. At a later time, an application of the compute device may want to know an estimate of the current maximum downlink bitrate, such as for the purpose of selecting a bitrate in streaming a video. The compute device can determine the current maximum radio bitrate, and look for similar entries in the database. Based on entries in the database, a link capability estimation can be determined and provided to the application.

  • Patent number: 10306182
    Abstract: A user equipment (UE) and method of improving video call quality during handover are generally described. After determining that handover has started (306), the UE may suspend (308) frame transmission and store the frames. After determining that handover has completed (310), the UE may discard (312) frames whose age exceeds a predetermined percent of a latency deviation computed from a real-time transport control protocol report. The UE may determine whether transmission of the remaining frames would exceed a delay proportional to a video frame interval multiplied by an uplink bandwidth for a cell to which the UE is connected or a maximum bitrate of a guaranteed bitrate bearer multiplied by a typical period for a non-access stratum bandwidth and discard frames in order of decreasing age until neither the bitrate nor the delay is exceeded by the transmission.

  • Patent number: 10271374
    Abstract: The UE VoIP engine monitors the network pattern periodicity and implements a scalable scheduling strategy that can adapt the VoIP engine and audio driver scheduling to the current local radio configuration in one embodiment. By adapting its scheduling, the VoIP engine can reduce mouth-to-ear delay or power consumption without impacting the audio encoding quality. The UE VoIP engine sends some scheduling preference to the network base station. The network base station monitors UE preferences and decide whether to ignore or accept UE preferences and allows the UE to operate in the conditions that provides the best tradeoff between power consumption and mouth-to-ear delay.
