An exemplary method embodiment includes operating a first Citizens Broadband Radio Service Device (CBSD) to: (i) establish a wireless device to device (D2D) communications link with a second CBSD using D2D wireless communications resources; (ii) send, via the D2D communications link, a first backhaul resource reservation signal to the second CBSD to reserve a first portion of a communications backhaul extending from the second CBSD to a service provider communication network; and (iii) communicate data for a user equipment device (UE) being served by the first CBSD to said service provider communications network via said D2D communications link and the communications backhaul extending from the second CBSD.

Abstract: Techniques for dual connectivity control based on downlink data are discussed herein. A Fourth Generation (4G) base station can receive downlink data to be transmitted to a user equipment (UE). The 4G base station can also receive data from the UE indicating that the UE is associated with a low power state. The 4G base station can further determine a capability of the base station (e.g., an available bandwidth) to transmit the downlink data to the UE. If an amount of downlink data is below a threshold, operations can refrain from establishing a dual connectivity connection. If an amount of downlink data is above a threshold, operations can include establishing a dual connectivity connection. In some cases, thresholds and/or the decision to initiate dual connectivity can be determined based on the state data associated with the UE, such as a battery status, a level of user interaction, and the like.

Abstract: A communication channel merging system detects that a first communication session that is provided via a first communication channel between a first user and a first service provider is concurrent with a second communication session that is provided via a second communication channel between the first user and a second service provider. The system then generates a user score based on information associated with the first and second communication sessions and determines that the user score satisfies a condition that causes the first and second communication sessions to be merged into a merged communication session. The system generates a first channel score for the first communication channel and a second channel score for the second communication channel and determines based on those channel scores that the first communication channel should provide the merged communication session. The system directs the merged communication session to be provided on the first communication channel.

Abstract: The present disclosure describes a method for characterizing a maximum frame size in a network data transmission with a feedback loop. A source device transmits a set of current frames with an initial frame size to a designation device, and receives returning frames from the designation device via a loopback interface. The frame size of subsequent frames to be transmitted is adjusted in bytes. The adjustment of the frame size may be based on a predetermined condition related to the returning frames. The maximum value of the frame size satisfied with the predetermined condition may be designated as the maximum frame size. A plurality of algorithms and machine learning may be used to project the frame size of the subsequent frames and obtain a precise value of the maximum frame size in a network route.

In some embodiments, the security configuration switch is explicitly signaled and is checked based on deciphering failure. In some embodiments that use make before break handover techniques, a source base station may be retained after the path switch.
