Abstract: Systems and methods herein utilize interworking protocols with centralized functionality to perform CSFB with minimal latency for an inbound and/or outbound communication with a mobile device that is attached to a communication network not operable to service the communication. Embodiments utilize a centralized gateway that communicates in both an LTE network and CS network. In embodiments, the mobile device may be concurrently attached to the LTE network, registered with the centralized gateway, and registered with an MSC of the CS network. Upon the CS network receiving an inbound call for the mobile device or upon the mobile device originating a call, the MSC may set up the call with the mobile device with minimal latency because the mobile device is pre-registered with the MSC.

Abstract: Systems and methods optimizing backhaul transport with respect to communication systems through the use of a heterogeneous backhaul link configuration and corresponding implementation of backhaul link path selection control to provide traffic offloading for traffic congestion mitigation are disclosed. Heterogeneous backhaul link configurations may include one or more backhaul links implementing a plurality of data paths providing different capabilities, such as may comprise a high reliability path and an unpredictable reliability path. Backhaul link path selection control of embodiments implements logic for determining when data is to be carried via one or more of the backhaul link paths.

Abstract: Performance in multiple-input-multiple-output (MIMO) antenna systems may be enhanced by configuring beams in a direction that reduces coupling between the beams. A decoupling metric may be calculated based on signal strengths received through the beams when an antenna system is pointed in different directions. The decoupling metric may be used to select a particular direction for operation of the antenna system. The decoupling metric may be combined with the signal strengths from each beam to select a direction for the antenna. An interface provides information to a user during positioning of the antenna to allow the user to select a direction for placement of the antenna that reduces coupling between beams in the MIMO antenna system.

Abstract: Systems and methods which provide resource sharing techniques implementing opportunistic shared resource utilization using dynamic traffic shaping are disclosed. Embodiments implement a multi-part transmission frame generation process in which data packets of various different traffic flows are selected for the transmission frame to fill the frame capacity. For example, scheduling logic may apply traffic shaping logic to select data packet queues from which data packets are to be included in a frame and to initially determine a number of packets to be included in the frame from each selected data packet queue according to the traffic shaping logic. Thereafter, the frame may be analyzed to determine if excess capacity remains. The scheduling logic may then apply traffic shaping logic to the data packet queues to implement an opportunistic scheme for including additional data packets in the frame and thereby fill the excess capacity.
