Abstract
Embodiments include a method performed by a data collection coordination function (DCCF) of a communication network. Such a method includes receiving a first service request for data from a service consumer network function (NFc) and determining a service producer network function (NFp) that will generate the data. Such a method includes sending a request for a second access token to a network repository function (NRF) that grants the DCCF permission to access the data on behalf of the NFc. The request includes a client credential assertion (CCA) associated with one of the DCCF and NFc and an additional credential assertion (ACA) associated with the other of the DCCF and NFc. Such a method includes receiving a second access token from the NRF, which includes a subject claim identifying one of the DCCF and NFc and an additional claim identifying the other of the DCCF and NFc. Such a method includes sending a second service request to the NFp, which includes the second access token, the CCA, and the ACA.
