  • Patent number: 11172267
    Abstract: A method of downloading video contents from a content server to a client through a base station of a wireless communication network is provided. Each video content includes a sequence of encoded video frames. The method includes having the content server send a video content in a sequence of data packets, each data packet including data corresponding to at least one portion of an encoded video frame, and having a proxy server at the base station classify each data packet according to the type of video frame it correspond to. The method also includes having a scheduler at the base station assign radio resources for the transmission of the data packets to the client based on the classification carried out by the proxy server, and transmitting the data packets to the client by exploiting the radio resource assignment carried out by the scheduler.

  • Publication number: 20200084254
    Abstract: A method of downloading a multimedia content from a content server to a client through a wireless communication network is provided. The multimedia content is subdivided into a plurality of chunks and for each chunk the content server has at least two corresponding versions thereof encoded with different encoding rates. The method includes having the client send a first request of a first version of a corresponding requested chunk, and having a proxy server intercept the first request to generate a second request of a second version of the requested chunk. The method also includes having the proxy server send the second request to the content server in place of the first request, and having the content server send the second version to the client. The second request is generated based on the amount of information content of the versions of said requested chunk.

  • Patent number: 9730242
    Abstract: A method for scheduling radio resource allocation among active flows within a wireless communication network. The method includes, at each working period of the scheduling method; for each active flow, checking presence of priority data to be transmitted within the current working period. Each active flow having priority data to be transmitted within the current working period is classified as a priority active flow. The remaining active flows are classified as non-priority active flows, the non-priority active flows having non-priority data that need not to be transmitted within the current working period. Radio resources are allocated among the priority active flows, and corresponding priority data are transmitted over the respective allocated resources. After completing priority data transmission, the radio resources are allocated among the non-priority active flows and corresponding non-priority data are transmitted over the respective allocated radio resources until the end of the current working period.

  • Patent number: 9107150
    Abstract: A method scheduling link activations within a wireless communications network including at least one network cell including a base station providing radio coverage over the network cell and at least one relay node putting the base station into communication with a user equipment within the network cell over an access link. The relay node communicates with the base station over a backhaul link. The method includes estimating, for the relay node, an access link capacity according to status information indicative of a status of the user equipment associated with the relay node, estimating a backhaul link capacity of the relay node according to the status information, and scheduling, for the relay node, either a backhaul link activation or an access link activation such that one of the backhaul link and access link is activated, in a predetermined time interval, based on a comparison between the access capacity and backhaul capacity.

  • Patent number: 8964867
    Abstract: A method executed in a wireless communication network including at least one base station associated to a corresponding area transmitting/receiving data to/from corresponding user terminals located within the area. The method generates a user-rate matrix for each base station. Each element of the user-rate matrix provides a corresponding score, in terms of achievable rate, to a user terminal or group of user terminals within the corresponding area when a transmission is made to/from the user terminal or group of user terminals, respectively, from/to the base station by employing a selected transmission mode. The method further processes the elements of the user-rate matrix to create a scheduling list sorting the elements by a decreasing score, and associating to each user terminal a corresponding selected transmission mode based on the scheduling list for the transmission/reception of data to/from the base station.

  • Patent number: 8913590
    Abstract: Disclosed herein is a method of managing a hybrid network including a cellular network and a local network wherein a number of dual mode mobile terminals are connectable to a base station of the cellular network through a direct cellular link and are also connectable, one with respect to the other, through the local network by a radio access technique. The method includes the steps of computing a cost associated with a direct connection established along a path (A) extending from a selected mobile terminal to the base station through the cellular link only, computing a cost (Ccg) associated with at least one indirect connection established along a path (B) extending from the selected mobile terminal to the base station through the local network and the cellular network, and selecting for data transmission the path that minimizes the cost.
