  • Publication number: 20260205379
    Abstract: Aspects of the subject disclosure may include, for example, an intent-based network (IBN) management system that effects changes in a communication network based on high-level intents. High-level intents are translated into operator-level intents by a large language model (LLM). Conflicts between operator-level intents are resolved, and the operator-level intents are mapped to intent functions. The intent functions are then mapped to policies that may effect changes in the network in accordance with the high-level intents. Other embodiments are disclosed.

  • Patent number: 8447968
    Abstract: The present invention provides a method for encrypting data for transmission over a wireless link. The method includes encrypting at least one block of data, at an air-interface application layer, using an encryption algorithm that receives a cryptosynch as input. The value of the cryptosynch is based on an order of the at least one block of data relative to other blocks of data. The value of the cryptosynch is recoverable by a receiver based on the ordering of the ordering of the blocks of data. The at least one encrypted block of data is transmitted to a receiver that is operable to preserve the order of the at least one block of data relative to the other blocks of data.

  • Patent number: 8121187
    Abstract: A Multiple Bit Rate (MBR) video coding method and apparatus for performing video encodings at multiple bit rates and for performing advantageous switching therebetween. Frequent switching points and high video coding efficiency are achieved with use of a plurality of video encodings at each of a plurality of bit rates, wherein the switching points between multiple encodings at a given bit rate are shifted with respect to one another so that the frequency of available switching points is significantly improved without a corresponding loss of coding quality. In addition, one or more “high quality” encodings may be provided at each bit rate, wherein the “high quality” encodings employ infrequent switching points, providing a very high quality encoding at the given bit rate which may be used (or switched to) whenever possible.
