  • Publication number: 20260303600
    Abstract: Embodiments include methods performed by a data collection coordination function (DCCF) of a communication network. Such methods include receiving from a service consumer network function (NFc) a first service request for data and determining a service producer network function (NFp) that produces the data. Such methods include sending to a network repository function (NRF) a request for a second access token granting DCCF permission to access the data on behalf of NFc. The request includes client credentials assertion (CCA) associated with one of DCCF and NFc, and additional credentials assertion (ACA) associated with the other of DCCF and NFc. Such methods include receiving from the NRF the second access token, including subject claim identifying one of DCCF and NFc and additional claim identifying the other of DCCF and NFc.

  • Patent number: 12730582
    Abstract: A memory device includes a memory array configured as quad-level cell (QLC) memory and a control logic operatively coupled to the memory array. The control logic identifies a first two bits of particular pages of a QLC logical state. The control logic causes memory cells of the memory array to be coarse programmed with a threshold voltage distribution of a multi-level cell (MLC) logical state corresponding to the first two bits. The control logic reads the MLC logical state from the memory cells and a second two bits from a cache buffer to determine the QLC logical state. The control logic causes the memory cells to be further coarse programmed with a QLC threshold voltage distribution corresponding to the QLC logical state.
