  • Publication number: 20240155474
    Abstract: In one illustrative example, a controller for use in a private mobile network may determine network service requirements for an industrial device. The controller may select, from a set of network slices, a subset of network slices having network service requirement configurations that most closely support the network service requirements. Each network slice of the set may be associated with an affinity ranking value that is indicative of a service performance of the network slice for industrial device operation in a cell or a zone associated with a zone or security level value assigned to the industrial device. The controller may identify, from the subset of network slices, a selected network slice associated with a best affinity ranking value for the zone or security level value assigned to the industrial device. The controller may assign the selected network slice and associated service parameters for the communications of the industrial device.

  • Patent number: 11678228
    Abstract: In one illustrative example, a user plane (UP) entity for use in a mobile network may receive a data packet from a user equipment (UE) operative to communicate in one or more sessions via a serving base station (BS) (e.g. eNB or gNB) of the mobile network. The UP entity may detect, in a header (e.g. SRH) of the data packet, an identifier indicating a new serving BS or session of the UE. The identifier may be UE- or BS-added data (e.g. iOAM data) that is inserted in the header by the UE or BS. In response, the UP entity may cause a message to be sent to an analytics function (e.g. a NWDAF) to perform analytics for session or flow migration for the UE.
