  • Patent number: 9155101
    Abstract: Embodiments relate to systems and methods for dynamic association ordering based on service differentiation in wireless local area networks. A WiFi™ or other access point can broadcast beacon information to surrounding stations, and receive probe requests from those stations seeking to associate with the access point. The access point can determine a classification for each station, depending on station attributes such as subscription status, handoff status, or others. Stations receiving a higher classification can enter the association process sooner than those with lower classifications. The association order can be managed by inserting a delay in the probe response, by broadcasting the classifications which will be processed in the next beacon interval, or by adjusting the order in which association steps will be performed.

  • Patent number: 9154588
    Abstract: Robust Header Compression (ROHC) offers a way to compress packet header information for more efficient transmission of data. The compression is achieved through various confidence modes set up by the transmitter and the receiver. The Initialization and Refresh state (IR) is the first state of the compressor. This provides a complete, uncompressed context of the data that is being transmitted. In typically operation, the ROHC compressor will periodically transmit IR packets providing context information allowing the ROHC decompressor to decompress one or more packets following the IR packet. However, under certain conditions such as decompressor start-up, it is possible for the decompressor to miss an IR packet. Exemplary methods and apparatus are described in which a decompressor uses a later-received IR packet to decompress earlier packets for which the decompressor had not received context information.

  • Patent number: 9137304
    Abstract: A distributed cloud storage system includes a cloud storage broker logically residing between a client platform and a plurality of remote cloud storage platforms. The cloud storage broker mediates execution of a cloud storage process that involves dividing a data item into multiple portions and allocating the portions to multiple selected cloud storage platforms according to first and second rules defining a key known only to the cloud storage broker or to the client. At some later time when it is desired to retrieve the data item, the key is retrieved from storage and the rules are executed in a reverse fashion to retrieve and reassemble the data item.

  • Patent number: 9130866
    Abstract: In one embodiment, a network frame is received at flow aware navigator between a client computer and a server computer. The flow aware navigator is configured to determine whether the network frame should be forwarded to one or more network services for processing before forwarding the network frame to the server computer. If the flow aware navigator determines that the network frame should be forwarded to one or more network services for processing before forwarding the network frame to the server computer, the flow aware navigator forwards the network frame to the one or more network services for processing. In response to receiving the processed network frame from the network services, the flow aware navigator then forwards the processed network frame to the server computer.

  • Patent number: 9131477
    Abstract: A system and method for addressing RLC unrecoverable errors experienced by User Equipment (UE) in a wireless network help the network to resolve the errors without shifting the UE into an Idle mode and dropping voice calls. A measurement event provides the buffer occupancy and identifies the affected radio bearer to the network. If the state of the bearer is not changed, the UE provides a Signaling Connection Release Indication message or a Radio Bearer Release Indication message to the network, the latter message identifying the radio bearer to be released without taking down the entire signaling connection for the domain.

  • Patent number: 9118473
    Abstract: Certain aspects of the present disclosure provide techniques and apparatus for combining the data (e.g., the channel station information (CSI) and the block acknowledgment (BA)) from one or more stations (STAs) capable of multi-user (MU) transmission in an effort to reduce the number of frames involved in a MU frame exchange. For certain aspects, the BA frames may be moved before a MU transmission and combined with the CSI frames, thereby effectively acknowledging a prior MU transmission. By reducing the number of frames involved, the efficiency of MU exchanges may be increased.

  • Patent number: 9083431
    Abstract: A modulator generates a modulation signal from an input signal. A serial-parallel converter generates a subcarrier modulation signal from the modulation signal. An IFFT unit performs an inverse fast Fourier transformation on the subcarrier modulation signal, generating first data. A decomposer decomposes the first data into real data and imaginary data. An operator performs a predetermined operation using a predetermined threshold value, a boundary value and the real data, generating positive data and negative data. Another operator performs a similar operation on the imaginary data. A generator adds the positive data and negative data based on the real data, and adds the positive data and negative data based on the imaginary data, generating real operation data and imaginary operation data. A synthesizer synthesizes both operation data to generate a baseband signal. A transmitter generates a transmission signal from the baseband signal, and transmits it to another apparatus via an antenna.

  • Patent number: 9042297
    Abstract: A first node receives information associated with a mobile station to allow for establishment of a session for the mobile station that is attached to a first wireless access network in a first service domain. In response to the received information, the first node sends messaging to a home agent in a second service domain that is of a different type than the first service domain. The first node receives, from the home agent, an Internet Protocol (IP) address allocated to the mobile station in the second service domain, where the IP address is allocated in response to the messaging, and where services provided to the mobile station are anchored in the second service domain.

  • Patent number: 9026591
    Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for forming communication threads. A system configured to practice the method receives a first log of first communications in a first modality and receives a second log of second communications in a second modality. Then, the system analyzes the first log and the second log to determine relationships between the first communications and the second communications. The system identifies, based on the relationships, sets of communications having a relationship strength above a threshold, and can form communication threads based on the sets of communications. The system can form communication threads by adding a meta-data tag to a communication unit. Example modalities include short message service (SMS), text, instant messages, phone calls, video calls, emails, events, social networking, and voicemail. The system can further rank the importance of communications threads based on user actions, to yield an importance value.
