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 method and apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.

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.

Abstract: A method and apparatus to help minimize tuneaway time of a user equipment device (UE), by dynamically scheduling when the UE should tune away to scan for coverage of a particular wireless communication system, such as a time division duplex (TDD) system for instance. The UE may receive downlink transmissions from a TDD system and determining a downlink transmission schedule of the TDD system based on when those downlink transmissions occurred. Further, the UE may then use the determined downlink transmission schedule as a basis to schedule tuneaway of the UE from a serving system to scan for coverage of the TDD system.

Abstract: Described are various approaches for considering inter-base-station link congestion levels in connection with handoff of a mobile station when the source base station (or another entity) is able to select a target base station for handoff from among a plurality of base stations. In one aspect, the plurality of base stations are each communicatively linked via a respective inter-base-station link with the source base station serving the mobile station. The source base station (or another entity) selects the target base station from among the plurality of base stations based at least in part on a congestion level of each base station's respective inter-base-station link. The source base station then hands off the mobile station to the target base station.

Abstract: A method and system for vertical handoff of a mobile station from a first-protocol RAN to a second-protocol RAN. The method and system provide a make-before-break vertical handoff, by having the first-protocol RAN (i) acquire, on behalf of the mobile station, a traffic channel assignment defining one or more traffic channel parameters for air interface communication in the second-protocol RAN, and (ii) pass to the mobile station, via the first air interface protocol, the one or more traffic channel parameters so that the mobile station can then readily switch over to communication under the second-protocol RAN. Optimally, the acquisition and passing of the one or more second-protocol traffic channel parameters may occur without the mobile station having requested the handoff, without the mobile station having asked for the traffic channel assignment, and without the mobile station having yet begun communication with the second-protocol RAN.

Abstract: An access terminal establishes a session with a first radio access network (RAN). As a result, the access terminal receives a Unicast Access Terminal Identifier (UATI) assigned by the first RAN and establishes configuration settings for radio communications between the access terminal and the first RAN. The access terminal moves from the first RAN to a second RAN. Before the access terminal has a session established with the second RAN, the access terminal receives a request from a user to originate a call. In response, the access terminal sends the second RAN a connection request that includes the UATI assigned by the first RAN. The second RAN evaluates the UATI included in the connection request and determines that it was previously assigned to the access terminal by another RAN. Based on this determination, the second RAN grants the connection request by assigning a traffic channel to the access terminal.

Abstract: Methods and systems are disclosed that may help a base station to adjust forward-link data rates in a given sector based on transmission-power variations in neighboring sectors. An exemplary method involves a base station that serves a first sector: (a) determining a respective transmission power for each of two or more channels of a second sector, (b) detecting a transmission-power difference between at least two of the channels of the second sector, and (c) in response to detecting the transmission-power difference: (i) determining a data rate control (DRC) adjustment for the first sector based at least in part on the transmission-power difference; and using the determined DRC adjustment to determine a forward-link data rate for at least one access terminal in the first sector.
