Abstract: A base station could establish maximum transmit power that the WCD should apply per carrier when serving the WCD on multiple carriers, with the base station considering the WCD's total power headroom and a delta of the WCD's uplink receive power per carrier. For instance, the base station could determine the WCD's total power headroom and could determine a receive power delta per carrier, the base station could effectively re-distribute the WCD's total power headroom among the carriers as adjustments to the maximum transmit power per carrier in accordance with a relative comparison of the receive power deltas on the carriers, the base station could further shift the adjustments to keep the sum of the WCD's maximum transmit power of the carriers in line with the WCD's maximum total transmit power, and the base station could direct the WCD to apply the shifted adjusted maximum transmit values.

Abstract: Disclosed is a method and system of selecting a quality of service (QoS) level for a bearer. According to the disclosure, a network controller may track a level of congestion of a base station and report that congestion information to a policy server. Thereafter, the policy server may receive a message indicating that a new bearer is needed for a communication session with a user equipment device (UE) being served by the base station. In response, the policy server may select a QoS level for the new bearer based at least in part on the based station's level of congestion (and also perhaps based on a type of the communication session), and the policy server may then invoke use of the selected QoS level for the new bearer.

Abstract: During the operation of a radio access network (RAN), the RAN will determine a measure of capacity of a frequency channel based on a modulation quality (Rho) of the frequency channel and will intelligently manage use of the frequency channel based on the determined Rho. Through this process, the RAN may thereby attempt to serve each WCD with an appropriate level of service by reducing a maximum load level for the frequency channel. In response to a WCD attempting to register on a frequency channel, the RAN may determine if registering the WCD would cause a current load level to exceed the maximum load level of the frequency channel. If registering would cause a current load level of the frequency channel to exceed the maximum load level, the RAN may cause the WCD to register on a different frequency channel. If not, the RAN may allow the registration.

Abstract: Examples disclosed herein include methods, systems, and devices to help a UE to securely output a copy of a security key stored on the UE. According to examples, a UE receives a test security key from a provider. Based on the received test security key, the UE computes a test result, and then the UE transmits the computed test result to a network authentication system. The UE receives from the network authentication system a response indicating a match between the computed test result and a test result computed by the network authentication system. Based on the received response indicating the match, the UE outputs a copy of the security key stored in the UE to the provider.

Abstract: Disclosed is a method and system for use of orthogonal coding to manage control channel load. Based on evaluation of downlink air interface load, a base station dynamically toggles use of orthogonal coding of downlink control information (DCI) messages for transmission on a downlink control channel. When downlink load is high, the base station may responsively operate in a state in which the base station orthogonally codes DCI messages to facilitate transmitting multiple DCI messages per set of resource elements on the downlink control channel, possibly boosting transmission power in those resource elements to help facilitate successful transmission. Whereas, when downlink load is not high, the base station may responsively operate in a state in which the base station does not orthogonally code DCI messages and thus sends just one DCI message per set of resource elements.

Abstract: A method and apparatus in which (i) a user equipment device registers with a first radio access network (RAN) that provides connectivity with a transport network, (ii) once registered with the first RAN, the device then registers via the first RAN and transport network with a call server, and (iii) in response to the device registering with the call server, but before the device then engages in a call served by the call server, the device registers via the first RAN with a second RAN. The method may thereby help to expedite later handover of a call served by the call server from being via the first RAN to being via the second RAN. Further, by the second RAN registration being conducted in response to registration of the device with the call server, the method may help to ensure usefulness of the registration of the device with the second RAN.

Abstract: A method and system for managing connectivity when a signaling controller is going to be taken out of service. The method involves determining that a WCD served by the signaling controller provides wireless backhaul connectivity for a relay base station, and responsively taking action to proactively transition that WCD from being served by the signaling controller to being served by a different signaling controller without the WCD detaching and reattaching. This may enable the WCD to maintain its network connectivity, including its assigned network address, and may thus enable the relay base station to maintain its network connectivity as well, thereby helping to maintain connectivity for WCDs served by the relay base station and continuity of interfaces between the relay base station and other core network entities.

Abstract: A computing system includes or has access to data records that associate (i) radio frequency (RF) signatures of device coverage from a base station with (ii) locations of devices corresponding with the RF signatures. When a device whose location is at issue is then within coverage of that base station, the computing system receives an RF signature of the device's coverage from the base station, and the computing system (i) finds multiple data records whose RF signatures of coverage from the base station most closely match the received RF signature, (ii) based on the device locations in the multiple data records, determines a representative bearing from the base station and a representative distance from the base station, and (iii) estimates the device's location to have the determined representative bearing and determined representative distance. The estimated device's location may then be used as a basis to provide a location-based service.

Abstract: Disclosed is a method and system to help manage data buffering, which may in turn help manage air interface resources. In accordance with the disclosure, when a base station detects transmitting data transmission to a WCD at a rate exceeding a defined rate cap, the base station may then predict how long it will be before a data buffer that would hold excess data for transmission to the WCD would reach a threshold fill level where the base station would increase air interface resources used for transmission to the WCD. The base station may then determine, based at least on that predicted duration, whether and/or to what extent to the increase the threshold fill level of the buffer, to help defer the buffer from reaching the threshold fill level, and thus to help defer increasing of air interface resources used for transmission to the WCD.

Abstract: A base station and a user equipment (UE) device may communicate over an air interface using a frequency division duplexing (FDD) configuration that provides a time sequence of consecutive subframes for both uplink and downlink communications. A transmitter (either the UE device or the base station) may select a sequence of N subframes for N transmissions of the same data to a receiver using transmission time interval (TTI) bundling, wherein successive subframes in the sequence are separated by one or more subframes. The transmitter may transmit the data M times (where M
