  • Patent number: 11082956
    Abstract: In one embodiment, a method is performed by a base station in a wireless network. The method includes receiving from a user device a request to reconfigure already-active uplink semi-persistent scheduling (SPS). The already-active uplink SPS grants the user device a resource block allocation (RBA) and a modulation and coding scheme (MCS) for periodic uplink transmissions. The already-active uplink SPS includes a time-interval parameter, the time-interval parameter specifying a time interval between the periodic uplink transmissions. The request includes information related to a proposed adjustment of the time-interval parameter. The method further includes reconfiguring the already-active uplink SPS. The reconfiguring includes modifying the time-interval parameter based, at least in part, on the information.

  • Patent number: 9781199
    Abstract: A method, system and apparatus are provided for performing peer-to-peer (P2P) data sharing operations between user equipment (UE) devices in a wireless-enabled communications environment. A first client node comprises content data and operates in a server peer mode to provide content data. A second client node submits a request to a P2P application server (P2P AS) for the content data. In response, the P2P AS provides the address of the first client node to the second client node. The second client node then uses the provided address to submit a request to the first client node to provide the content data. The first client node accepts the request and then provides the content data to the second client node.

  • Publication number: 20140243101
    Abstract: Systems and methods that deliver game supplies are described. In some embodiments, a method receives a request for in-game supplies from a first player in an interactive social game. The method presents multiple supply options where each supply option has an associated processing time. A supply option selection is received from the first player that indicates selection of one of the multiple supply options. A supply fulfillment invitation is distributed to a second player of the interactive social game. An in-game benefit is provided to the second player in response to acceptance of the supply fulfillment invitation. The first player is notified upon completion of the processing time for the selected supply option, which indicates availability of the requested in-game supplies to the first player.

  • Patent number: RE46125
    Abstract: A method of relocating the header compression context in a packet network which transmits packets having compressed headers. A connection is established between a mobile terminal and a first network entity and context information used with compression and decompression of the headers of the packets is stored at the mobile terminal and the first network entity. The context information updating is stopped in the mobile terminal and in the first network entity and after that, a snapshot of the compression and decompression context information is taken and stored in the first network entity. The connection between the first network entity and the mobile terminal is changed to a connection between the mobile terminal and a second network entity. The context information snapshot stored by the first network entity is transferred to the second network entity to be stored therein as the context information of the second network entity.
