Abstract: A system and method of performing multi-layer client assurance in a private cellular network includes a plurality of assurance points within the network. The method includes receiving, by a network entity, a plurality of parameter sets from the plurality of assurance points. Each of the plurality of assurance points can be configured to obtain measurements from a portion of the private cellular network corresponding to a client assurance layer in a client assurance stack. The method can include combining a first parameter set from the plurality of parameter sets with a second parameter set from the plurality of parameter sets. The first parameter set can be associated with a first client assurance layer and the second parameter set is associated with a second client assurance layer. The method can include determining, based on the combined parameter set, a network service level corresponding to the client device.

Abstract: Generic bootstrapping architecture (GBA) based procedures over Constrained Application Protocol (CoAP) for use in authenticating and/or securing communications with Internet of Things (IoT) devices are provided. In one illustrative example, the device sends to a bootstrapping server function (BSF) a first CoAP request carried in a Confirmable (CON) message, where the first CoAP request indicates a request for initiating a bootstrapping procedure. In response, the device receives from the BSF a first CoAP response carried in an Acknowledgement (ACK) message, where the first CoAP response indicates an authentication challenge. The device sends to the BSF a second CoAP request carried in a CON message, where the second CoAP request includes a challenge response to the authentication challenge. The device receives from the BSF a second CoAP response carried in an ACK message, where the second CoAP response includes a bootstrapping transaction identifier (B-TID) which indicates a successful authentication. The device generates a bootstrapping session key (Ks) and stores it in association with the B-TID. An HTTP messaging-based server (e.g. BSF or NAF) may utilize a module, such as a plug-in module, for message translation between CoAP and HTTP.
