Abstract: A controller node in a network implementing software defined networking (SDN) proactively detects network overload conditions in a target node and subsequently prevents the conditions from developing by launching a new virtual network node. The detection and prevention are based on the determination of a probability of failure of the target node as a weighted function of information from the target node and probabilities of failure of related nodes.

Abstract: In mixed numerology case, the performance of a physical downlink shared channel (PDSCH) can be improved by multiplexing PDSCH of one numerology with the channel state information reference signals (CSI-RS) of the other numerology and use of an advanced receiver. However, due to the interference from the PDSCH of the other numerology, the channel estimation for the underlying UE can be impacted if the CSI-RS is corrupted. An adaptive CSI-RS configuration can be deployed where the CSI-RS density is adapted based on the PDSCH transmission of the other numerology. Namely, based on the scheduling decision of the other numerology, the CSI-RS density can be changed. Thus, the impact on channel estimation can be minimized when the data channel of one numerology is multiplexed with the CSI-RS of the other numerology.
Abstract: A method for vNF chaining management includes receiving virtualized network function (vNF) information from a chaining client associated with a particular vNF. A service chaining catalog is updated based on the vNF information and chaining information is transmitted to peering vNFs of the particular vNF. The vNF information can indicate instantiation of a vNF and identify peering vNFs. Updates received from vNFs can be used to update the chaining catalog. Updated vNF information can then be sent to peering vNFs of the vNF which sent the update.

Abstract: A system information block (SIB) in a radio interface is dedicated to broadcast data intended for Internet of things (IoT) devices. The data can be associated with most any IoT service, such as but not limited to, a vehicle-to-vehicle (V2V) and/or vehicle-to-everything (V2X) service. In one aspect, data, associated with an event, that has been aggregated from one or more IoT devices located within a region can be analyzed to determine a geographical area where a message regarding the event (e.g., accident) is to be broadcast. Further, the message can be dynamically prioritized and/or customized to target a particular class of IoT devices (e.g., connected cars) by employing different message identifiers.

Abstract: A pre-distortion system for improved mobile device communications via cancellation of nonlinear distortion is disclosed. The pre-distortion system may transmit an acoustic signal from a network to a device, wherein the acoustic signal includes a linear signal and a nonlinear cancellation signal that cancels at least a portion of nonlinear distortions created once a loudspeaker in the device emits the linear signal. Thus, when a loudspeaker of a mobile device is operating and nonlinear distortions are generated by the loudspeaker or adjacent components of the mobile device in close proximity to the loudspeaker, the pre-distortion system may create one or more nonlinear cancellation signals in the network. The nonlinear cancellation signal may be combined with the linear signal sent to the loudspeaker to cancel the nonlinear distortion signal created by the loudspeaker emitting acoustic sounds from the linear signal. Thus, the nonlinear cancellation signal becomes a pre-distortion signal.

Abstract: Mobile service anchor management (MSAM) is facilitated. MSAM is an anchor management function/system for radio frequency (RF) access configuration/reconfiguration over the downlink, and uplink separated novel frequency division duplex systems. One method comprises determining, by a MSAM system comprising a processor, that a mobile device communicatively coupled to a first network device is associated with a region in which the first network device fails to have line of sight communication with the mobile device; and assigning, by the mobile service anchor management system, the mobile device to a second network device determined to have the line of sight communication for the region. Millimeter watt (mmW) BS devices and devices that operate on other RF bands can be utilized.
Abstract: A more efficient network can be achieved by leveraging an adaptive dejitter buffer. The dejitter buffer can be dynamically adjusted based off a network data analysis.

Thereafter, the dejitter buffer memory can be filled with voice packet data to decrease a packet delay variation at the mobile device.

Abstract: A speed tier based pricing scheme is utilized to increase average revenue per user (ARPU). To offer a speed tier based pricing scheme, the radio environment at a location of the UE can be analyzed to determine the speed tiers that can be offered to the user. In one aspect, an outer-loop scheduler can be utilized to allocate radio bearers to the UE based on a target data throughout associated with a user-selected speed tier. The priority of the non-guaranteed bit rate (GBR) bearers of the UE can be dynamically adjusted to track the target data throughput. In another aspect, a throttling function can be implemented to limit the data throughput of the UE to the target data throughput.
