Abstract: Methods and systems for managing paging-channel resources, and in particular, dynamically adjusting the page-concatenation level based on PCO in a sector, are disclosed herein. An exemplary method involves (a) at an access network configured to page mobile stations via a paging channel of a sector in the access network, determining a paging channel occupancy (PCO) level for the sector; (b) using the determined PCO level as a basis for selecting a page-concatenation level to be used to page mobile stations in the sector, wherein the page-concatenation level is selected from a plurality of available page-concatenation levels; and (c) applying concatenation to pages to mobile stations in the sector according to the selected page-concatenation level.

Abstract: In a communication system comprising a base station having a set of carrier frequencies, ranging from a lowest to a highest carrier frequency, for serving user equipment devices (UEs), the base station may schedule a first transmission of first bearer traffic to be on a first carrier frequency of the set based at least in part on a correlation between (i) the first bearer traffic being of a first type of bearer traffic and (ii) where the first carrier frequency falls within the range of carrier frequencies. The base station may also schedule a second transmission of second bearer traffic to be on a second, different carrier frequency of the set based at least in part on a correlation between (i) the second bearer traffic being of a second, different type of bearer traffic and (ii) where the second carrier frequency falls within the range of carrier frequencies.

Abstract: Disclosed is a method and system for selecting a target base station for handover of a wireless communication device, where the selecting is based at least in part on a consideration of the target base station's typical control-plane signaling latency in a core network, and particularly based on a comparison of control-plane signaling duration of multiple candidate target base stations. For instance, where all of the base stations are configured to engage in a particular control-plane signaling transaction from time to time, at issue could be which of the candidate target base stations typically engages in that control-plane signaling transaction the quickest.

Abstract: An RF fingerprint of the environment of a base station antenna will be regularly monitored, such as by regularly evaluating various RF metrics of uplink reflections of downlink transmission from the antenna. Through regular monitoring of the RF fingerprint, a baseline RF fingerprint could be established. And through continued monitoring of the RF fingerprint, an unexpected change in the RF fingerprint could then be detected, as an indication that the antenna's RF beam direction may have changed. In response to detecting the unexpected change in the antenna's RF fingerprint, the antenna's RF beam direction could then be newly determined, and the antenna's configuration record could be updated to indicate the newly determined RF beam direction.

Abstract: Disclosed are methods and systems for selection of a handover target for a user equipment device (UE). In particular, a wireless communication system may serve the UE over an air interface connection between the UE and a source base station (BS). While the system serves the UE, the system may make a selection of a handover target for the UE. And in accordance with the disclosure, the selection may be based at least in part on the handover target not having a wireless relay backhaul connection. Once the system selects the handover target using the disclosed approach, the system may then trigger handover of the UE from being served by the source BS to being served by the selected handover target.

Abstract: A method is disclosed to help register a UE with a different network in the event of an unsuccessful registration with a fallback network. In accordance with the disclosure, a UE may be registered on a first network and may then seek to register with a second network via the first network. The first network may attempt to register the UE with the second network, but the attempt to register the UE with the second network may ultimately fail. In response to such failure, the first network may discontinue providing service to the UE. Discontinuing the providing of service to the UE on the first network may result in the UE seeking to register directly with the second network or with a different network. By registering directly with the second network, or a different network, the UE may be able to initiate and/or receive voice calls via that network.

Abstract: A method and system for managing time segments per subframe used for downlink control channel communication by adjacent base stations. The base stations may work with each other to arrange for their respective use of different time segments per subframe for their respective downlink control channel use. Further, each base station may also avoid downlink traffic channel communication in the time segments per subframe that the other base station will be using for control channel communication.

Abstract: Disclosed is a method and system of imposing a policy rule for excessive usage in an access network. According to the disclosure, a policy enforcement point (PEP) may detect that usage by a given client device is threshold high and responsively request, from a policy decision point (PDP), a policy directive that specifies a policy rule to apply to the given client device. However, thereafter, the PEP may determine that the requested policy directive has not been received from the PDP and then responsively apply, to the given client device, a default policy rule for threshold-high usage.

Abstract: Methods and systems for making decisions regarding handing off a user-equipment device from a serving base station to a neighboring base station. Base stations in a wireless communication network measure parameters regarding forward-links from the base stations and reverse-links to the base stations. Each base station transmits its measured parameters to its neighboring base station(s). Each base station can determine differences between the parameters it measures and the parameters measured by a neighboring base station. The differences indicate whether the quality of service provided by the serving base station is greater than the quality of service provided by a neighboring base station. The servicing base station transmits the differences to user-equipment devices served by that base station. The user-equipment device compares the differences pertaining to the serving base station and multiple neighboring base stations and selects a neighboring base station to which the user-equipment device is to be handed over.
