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 an initial transmit power to a particular WCD based on the particular WCD's altitude. For instance, if the particular WCD is above a threshold altitude, the RAN may set the initial transmit power to the WCD to a lower value. However, if the WCD is below the threshold altitude, the RAN may set the initial transmit power to the WCD to a higher value, to overcome low-altitude signal obstructions. As a result, RAN and WCD performance may improve.

Abstract: A wireless communication system transmits overhead messages including a plurality of message types using a first priority scheme that identifies a first priority for transmitting the plurality of overhead messages based on the plurality of message types. The wireless communication system receives and processes call information to indentify a rate of call a rate of call originations. The rate of call originations is then processed to determine a second priority scheme that identifies a second priority for transmitting the plurality of overhead messages based on the plurality of message types if the rate of call originations exceeds a threshold. The wireless communication system then transmits the overhead messages using the second priority scheme if the rate of call originations exceeds the threshold.

Abstract: A first base station transceiver wirelessly receives communications from a first user in a code division multiplexing format using a first code assigned to the first base station transceiver. A second base station transceiver wirelessly receives communications from a second user in the code division multiplexing format using a second code assigned to the second base station transceiver. The base station transceivers determine and transfer wireless communication performance measurements. A network control system selects the second base station transceiver to assist the first base station transceiver based on the communication performance measurements. In response, the second base station transceiver wirelessly receives communications from a third user in the code division multiplexing format using the first code assigned to the first base station transceiver.

Abstract: The invention is directed to methods and systems for controlling resource utilization. In particular, resources in a wireless telecommunications network may be monitored and controlled to eliminate unnecessary resource usage. Channels on the network, and the users thereof, may be monitored to identify under-utilized channels based on predetermined thresholds. If an under-utilized channel is identified, users may be immediately or subsequently transferred to another channel on the network and resources to the under-utilized channel may be eliminated. The channels may be dynamically monitored such that any changes in usage are addressed and users may be transferred multiple times to conserve 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: 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: During a first time interval, an access point transmits orthogonal frequency division multiplexing (OFDM) signals using a first cyclic prefix length. The access point selects a second cyclic prefix length based, at least in part, on the load of the access point. The access point transmits OFDM signals using the second cyclic prefix length during a second time interval. The load of the access point may be determined based on the amount of downlink data being buffered in the access point for transmission to one or more user devices.

Abstract: Disclosed herein are methods and systems that may, among other possible benefits, help an access network to more quickly re-assign a forward traffic channel. An exemplary method involves an access network: (i) making a determination that a forward traffic channel is invalid, wherein the forward traffic channel is initially assigned to a first access terminal; and (ii) in response to the determination that the forward traffic channel is invalid: (a) after sending a first configuration message indicating that the forward traffic channel is invalid, waiting for at least a predetermined wait period before sending a second configuration message indicating that the forward traffic channel is valid; and (b) before the predetermined wait period has ended, making the forward traffic channel available for re-assignment to a second access terminal.
