Abstract: A method of managing modulation for transmission of data in anticipation of handover. When a source base station is serving a UE and determines that the UE is going to hand over to a target base station, the source base station automatically transitions to transmit data to the UE with a low-order MCS selected without regard to CQIs reported by the UE, or at least to apply an MCS corresponding with a CQI lower than that reported by the UE. By applying a low-order MCS to transmit data to the UE, the source base station may increase the likelihood that the data will arrive successfully at the UE, as the low-order MCS may be more tolerant to noise than higher-order MCSs.

Abstract: A base station may provide wireless service on an air interface that defines different mutually exclusive groups of random access channel (RACH) instances for different uses. In one example, the air interface may define a first group of RACH instances having groupings of preambles for designating a value of a characteristic, and define a second group of RACH instances that does not have groupings of preambles. As another example, the air interface may define a first group of RACH instances that has groupings of preambles for designating a value of a first characteristic, and define a second group of RACH instances that has groupings of preambles for designating a value of a second characteristic. The base station may then differentially handle random access requests based on whether the base station receives a preamble in a RACH instance of the first group or rather the second group.

Abstract: In order to provide better wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas that are configured to provide coverage at these different altitudes. The RAN may assign resources, such as transmit power or frequencies, to wireless coverage areas serving particular altitude ranges in a proportion that is commensurate with the number of WCDs being served by these particular altitude ranges. As a result, RAN and WCD performance may improve.

Abstract: A wireless communication device (WCD) may determine that the WCD has bearer traffic queued for transmission to a radio access network (RAN). The WCD may be configured to transmit the bearer traffic and neighbor reports over a reverse-direction channel of the RAN. The neighbor reports may contain information related to wireless coverage areas. One or more characteristics of the bearer traffic may also be determined. Based on the one or more characteristics of the bearer traffic, the neighbor reports may be scheduled to be transmitted over the reverse-direction channel at a particular rate. The WCD may transmit the neighbor reports over the reverse-direction channel at the particular rate.

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.

Abstract: A method and system to assign a contention-free access resource is disclosed. A first network may be configured to serve user equipment devices (UEs) according to a first protocol and a second network may be configured to serve UEs according to a second protocol. The method involves the first network detecting an attempt to set up a circuit-switched-fallback (CSFB) call between (i) a UE served by the first network and (ii) a remote party, where the CSFB call is to be served by the second network to which the UE would transition to be served with the CSFB call. The method further involves, in response to detecting the attempt to set up the CSFB call, the first network assigning a contention-free access resource to the UE, so as to allow a contention-free access request by the UE to the first network.

Abstract: As disclosed, while a wireless communication device (WCD) is idling on a particular carrier frequency of a base station, the base station may receive a message broadcast by that base station, the message specifying multiple relative sets of priority levels defined for a set of carrier frequencies and correlating each of the multiple relative sets of priority levels with respective different WCD operational characteristics. In particular, the message may specify a first correlation of one relative set of priority levels with one WCD operational characteristic and includes a second correlation of a different relative set of priority levels with a different WCD operational characteristic. The WCD may select one of the relative sets of priority levels responsive to the WCD having a WCD operational characteristic that the message correlates with the selected relative set of priority levels. The WCD may then apply the selected relative set of priority levels.

Abstract: Disclosed is a method and system to manage paging channels in a wireless communication network. When the network encounters a situation where the network is to transmit an access response message in a coverage area to a mobile station, the network will determine whether the mobile station is in an access handoff state. If not, the network will transmit the message to the mobile station on a paging channel selected based on the mobile station's identifier. Otherwise, the network will transmit the message to the mobile station on both that paging channel and a default paging channel (e.g., primary channel) selected without consideration of the mobile station's identifier. This process can help avoid an access handoff failure. Further, a radio access network may opt to use the default paging channel in response to the wireless coverage area having a different number of paging channels than an adjacent coverage area.
