Abstract: A method is performed at a gateway device including one or more processors and a non-transitory memory. The method includes, receiving, from a first wireless network, a first get authentication token request, where the first get authentication token request includes network information of a second wireless network and information of a first user equipment (UE). The method further includes forwarding the first get authentication token request to the second wireless network in response to receiving the first get authentication token request. The method additionally includes receiving a first authentication token from the second wireless network. The method also includes forwarding the first authentication token to the first UE via the first wireless network in order to associate the first UE with the second wireless network.

Abstract: Systems, methods, and computer-readable media for dynamically assigning devices to specific channels in the CBRS band. One or more dedicated channels within the CBRS band can be selected and a boost channel device group can be formed by exclusively allocating the one or more dedicated channel to the boost channel device group. Further, a normal channel device group can be formed by allocating, to the normal channel device group, one or more channels in the CBRS band that are separate from the one or more dedicated channels allocated to the boost channel device group. One or more devices communicating in the CBRS band can be selectively assigned to either the boost channel device group or the normal channel device group to selectively control communications in the CBRS band over the one or more dedicated channels utilized by the boost channel device group.

Abstract: A method of controlling performance of a wireless device is performed by a node that is in electronic communication with a cellular network. The node includes a processor, a non-transitory memory, and a network interface. The method includes receiving a performance value characterizing a performance of a communication channel between a wireless device and a wireless access point. In some implementations, the wireless device and the cellular network are associated with different radio access technologies (RATs). The method includes determining whether the performance value breaches a performance criterion for the wireless device. The method includes adjusting a first amount of data transmitted to the wireless device from a base station of the cellular network and a second amount of data transmitted to the wireless device from the wireless access point. In some implementations, the combined first and second amounts of data satisfy the performance criterion for the wireless device.

Abstract: Systems, methods, and devices are disclosed for providing a quality of service between nodes. A service provider can receive, from a first node of a customer network to an ingress node of a service provider network, packets bound for a second node on the customer network that is remote from the first node. The packets are mapped to a network segment according to a traffic type based on an identifier associated with the packets that identifies the traffic type of the packets. The packets are sent via their mapped network segment to an egress node with connectivity to the second node of the customer network according to a quality of service associated with the traffic type identified by the identifier.

Abstract: Systems, methods, and computer-readable media for radio resource management in a Citizens Broadband Radio Service (CBRS) network include one or more CBRS devices (CBSDs) which can obtain a group type associated with the CBSDs and their associated Radio Environment Map (REM) reports of one or more frequency channels of the CBRS network. The group type and the REM reports may be provided to a Self-Organizing Network (SON) manager of the CBRS network, where the SON manager may determine and provide to the CBSDs, one or more of a channel utilization information, transmission power, or mobility load management information for the CBSD, based on the group type and the REM reports.

Abstract: In one embodiment, a server generates expected levels of capability associated with possible combinations of settings for first and second adjustable parameters for an aspect of a software image feature. The server receives an indication of a desired level of capability for the aspect of the software image feature and, based on the indication, identifies a particular expected level of capability associated with a particular possible combination of the settings for the first and second adjustable parameters. The particular expected level of capability is closer to a desired level of capability for an aspect of a software image feature than the other expected levels of capability associated with the possible combinations of the settings for the first and second adjustable parameters. The server produces a software image that includes the particular possible combination of the settings for the first and second adjustable parameters.

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.
