    Abstract: Techniques are described to provide for authentication and subscription management that are decoupled from a Home Subscriber Server (HSS). In one example, a method includes providing a device profile at an authentication function, wherein the device profile comprises identification information for a device for a plurality of access types including a first identifier for the device associated with a cellular access and a second identifier for the device associated with a wireless local area network access; obtaining an access request message associated with the device for the cellular access, wherein the access request message comprises the first identifier and an authentication attribute; generating authentication information for authenticating the device for the cellular access based, at least in part, on the authentication attribute; and generating, for transmission, an access accept message for the cellular access, wherein the access accept message comprises the first identifier, the second identifier, and the authentication information.

    Abstract: Techniques for optimizing performance of narrowband Internet-of-Things (NB-IoT) devices in a wireless wide area network (WWAN) are described. In one embodiment, a method includes providing a NB-IoT base station in an in-band deployment mode to operate within a WWAN. The NB-IoT base station is configured to use a physical resource block of the WWAN for communicating with a plurality of NB-IoT devices. The method includes causing a reduction of a power level for a transmission from an initial power level to a first reduced power level. The method includes obtaining parameters associated with performance and throughput for the WWAN and comparing the parameters to a quality threshold. Based on the comparison of the parameters to the threshold, the method includes determining whether or not to reduce the power level for the physical resource block from the first reduced power level to a second reduced power level.

    Abstract: Various implementations disclosed herein enable controlling access to networks. In various implementations, a method of controlling access to a network is performed by a computing device including one or more processors, and a non-transitory memory. In various implementations, the method includes obtaining an indication that a mobile device having access to a first network utilizing a first radio access technology (RAT) has requested access to a second network utilizing a second RAT. In some implementations, the method includes determining whether the access to the first network satisfies an authentication criterion associated with the second network. In some implementations, the method includes granting the mobile device access to the second network in response to determining that the access to the first network satisfies the authentication criterion associated with the second network. In some implementations, accessing the second network via the authentication criterion satisfies an operating threshold associated with the mobile device.

    Abstract: A method is provided in one example embodiment and may include configuring a slice identity for each of a plurality of virtual radio access network (vRAN) slices, wherein each vRAN slice comprises functionality to perform, at least in part, one or more radio protocol operations on subscriber traffic; configuring an allotment of radio resources that can be utilized by each vRAN slice of the plurality of vRAN slices; receiving, by a slice manager, a subscriber profile identity (SPID) for a subscriber; and mapping the SPID for the subscriber to a particular vRAN slice of the plurality of vRAN slices. The method can further include communicating the mapping for the subscriber to the particular vRAN slice to which the SPID is mapped. The method can further include communicating the allotment of radio resources that can be utilized by the particular vRAN slice to the particular vRAN slice.
