  • Patent number: 12573382
    Abstract: Generally discussed herein are devices, systems, and methods for generating a phrase that is confusing to a language classifier. A method can include determining, by the LC, a first classification score (CS) of a prompt indicating whether the prompt is a first class or a second class, predicting, based on the prompt and by a pre-trained language model (PLM), likely next words and a corresponding probability for each of the likely next words, determining, by the LC, a second CS for each of the likely next words, determining, by an adversarial classifier, respective scores for each of the likely next words, the respective scores determined based on the first CS of the prompt, the second CS of the likely next words, and the probabilities of the likely next words, and selecting, by an adversarial classifier, a next word of the likely next words based on the respective scores.

    Abstract: Video decoding innovations for multithreading implementations and graphics processor unit (“GPU”) implementations are described. For example, for multithreaded decoding, a decoder uses innovations in the areas of layered data structures, picture extent discovery, a picture command queue, and/or task scheduling for multithreading. Or, for a GPU implementation, a decoder uses innovations in the areas of inverse transforms, inverse quantization, fractional interpolation, intra prediction using waves, loop filtering using waves, memory usage and/or performance-adaptive loop filtering. Innovations are also described in the areas of error handling and recovery, determination of neighbor availability for operations such as context modeling and intra prediction, CABAC decoding, computation of collocated information for direct mode macroblocks in B slices, reduction of memory consumption, implementation of trick play modes, and picture dropping for quality adjustment.

  • Patent number: 8774385
    Abstract: A service based Ringback Tone service that may be personalized by a calling party instead of a called party. The calling party generates and stores an originating profile that contains Ringback Tones or Ringback messages associated with a Ringback Tone subscriber (called party). When the calling party contacts the called party, the Ringback Tone chosen by the calling party and associated with the called party is then sent to the calling party until the calling party answers the call.

  • Patent number: 7702364
    Abstract: A base station in a wireless communication network saves connection information that enables it to recognize currently authenticated mobile stations. The base station carries out localized connection management processing for authenticated mobile stations, at least for certain types of packet data connection events. By carrying out localized processing, the base station skips the connection management signaling between it and a supporting mobile switching center that would otherwise be required for processing such events. Thus, in a cdma2000 base station embodying such localized processing, the MSC's involvement in packet data connection state transitions, short data burst deliveries, etc., can be eliminated or at least greatly reduced, thereby minimizing the MSC's role in supporting packet data services.

  • Patent number: 7295545
    Abstract: The invention relates to a method for maintaining a Point-to-Point Protocol (PPP) connection between a Mobile Terminal (MT) and a Packet Data Serving Node (PDSN). Responsive to a detection at the PDSN that the PPP connection between the PDSN and the MT is inactive, the method sends a first Link Control Protocol (LCP) Echo Request, which including a Short Data Burst (SDB) parameter, wherein the SDB parameter indicates that the message is sent using SDB, from the PDSN to a Base Station Controller/Packet Control Function (BSC/PCF) for locating the MT. The method further determines on the reception of SDB parameter, not to setup a traffic channel (TCH) between the MT and a serving BS. Next, the method sends from the BSC/PCF to the BS a second LCP Echo Request, which includes a NO Traffic Channel (No TCH) parameter instructing not to setup a traffic channel for the MT.

  • Patent number: 7103662
    Abstract: A system and method is disclosed for improved session management when roaming between access networks (AN) within a data cellular network. In one embodiment, gateway functionality is added to one AN in each subnet. The Gateway AN (GAN) provides session transfer capabilities during a dormant handoff with a source AN located in a different subnet. The GAN is responsible for receiving session information request messages from target AN's within the local subnet, querying other GANs within other subnets to locate the subnet that contains the source AN for the session and routing the session information back to the target ANs. In another embodiment, an extended session is established across several ANs within a subnet. When an Access Terminal (AT) initiates a new extended session, the responsible AN negotiates a common session across the ANs covered by the extended session area. During the session negotiation, each AN establishes a new session and allocates a new Unicast Access Terminal Identifier (UATI).

  • Publication number: 20050186971
    Abstract: A Base Station Controller (BSC) in a wireless communication network stores paging location information for a mobile station, and uses that information to determine whether paging the mobile station for mobile-terminated packet data delivery requires mobile switching center (MSC) involvement. For example, the BSC may send a service request message to the MSC to initiate paging of the mobile station by the MSC if the paging location information identifies a service area that is not exclusive to the BSC, and autonomously page the mobile station if the identified service area is exclusive to the BSC. Also, the BSC may autonomously page the mobile station along with sending a service request to the MSC, on the chance that the mobile station actually is within a service area controlled by the BSC. The BSC also may send a service request to the MSC if autonomous paging fails.

    Abstract: The present invention relates to method for integrating a Wireless Local Area Network (WLAN) and a Wireless Wide Area Network (WWAN) and to a Wireless Local Area Network Serving Node (WSN) therefore. For doing so, the WSN receives Remote Authentication Dial-In User Service (RADIUS) Request message from an Access Point (AP), the RADIUS Request message including terminal's credentials. The WSN proxies the RADIUS Request message at a RADIUS proxy capability. The WSN authenticates the terminal using the terminal's credentials. The WSN manages charging operation for the terminal.
