Disclosed is a method and apparatus and system for managing frequency use in a system where multiple air interface protocols are in use. When a wireless communication device (WCD) is operating under a particular air interface protocol on a particular frequency channel, the WCD detects a threshold signal under another air interface protocol, and the WCD responsively transitions from operating under the particular air interface protocol on the particular frequency channel to operating under the particular air interface protocol on a different frequency channel. The method may thereby help to reduce likelihood of interference.

A method and system for managing access probe transmission in a wireless communication system. Upon determining that an external impact event, such as a severe weather event, natural disaster, criminal activity, has occurred, base stations may wirelessly broadcast a control signal that causes certain wireless communication devices served by the base stations to suppress transmission of access probes, while allowing other wireless communication devices served by the base stations to still transmit access probes. In a given coverage area, suppression of access probe transmission by one or more wireless communication devices may thereby free up access channel capacity to facilitate calls or other communications by other wireless communication devices, such as first-responder devices for instance.

A method to help restrict operation of a mobile device in a situation where a user of the device may be distracted, such as when the user is driving a motor vehicle. The device presents the user with a test and reveals the solution to the test, and the user must then enter into the device the revealed solution within a predefined period of time. If the user enters the revealed solution within the predefined period of time, then a fair assumption is that the user is not distracted. On the other hand, if the user does not enter the revealed solution within the predefined period of time, then a fair assumption is that the user is distracted (e.g., is driving), in which case the device will responsively change an operational characteristic of the device so as to restrict the user's interaction with and operation of the device.

Disclosed is a method, system, and device for secret fingerprint scanning and reporting. When a portable communication device has been lost or stolen, an entity may transmit a fingerprint scan-report trigger message to the device. In response to receipt of the fingerprint scan-report trigger message, the device then automatically invokes an integrated fingerprint scanner to scan a fingerprint of a user of the device and to report the resulting fingerprint data to a remote destination. Optimally, the scanning and reporting are done without notification to a user of the device. The method, system, and device may thereby help to identify the user of the device and to potentially recover the device.

Methods and systems are provided for disabling text-entry capabilities. In one embodiment, a mobile station detects that it is being supported by a given single hand of a user and not by two hands of the user. The mobile station also detects that it is being operated by the single given hand of the user and not by two hands of the user. Optionally, the mobile station also determines that it is moving at greater than a threshold rate or detects more than a threshold degradation in text-entry proficiency. In response to detecting at least that the mobile station is being supported and operated by the single given hand of the user and not by two hands of the user, the mobile station disables one or more text-entry capabilities.

Methods and systems are provided for implementing predictive personality negotiation during session negotiation. In an embodiment, an EV-DO access node negotiates a first session with an access terminal, which involves negotiating a comprehensive set of personalities with the access terminal for the first session. The access node then records a list of personalities actually used by the access terminal during the first session. That list is a subset of the comprehensive set. The access node then negotiates a second session with the access terminal, which involves negotiating only that subset of personalities with the access terminal for the second session.

Methods and systems are provided for dynamic adjustment of forward-link traffic-channel power levels based on forward-link RF conditions. In an exemplary embodiment, a base station provides service on a carrier in a wireless coverage area. The base station computes an Ec/Ior value for the carrier. Based at least in part on the computed Ec/Ior value, the base station adjusts at least one of an initial traffic-channel power level, a minimum traffic-channel power level, and a maximum traffic-channel power level for the carrier. As an example, if Ec/Ior is above a certain threshold, the base station may increase all three of the power levels, so as to improve service quality and coverage of its traffic channels, among other advantages.
摘要:
Methods and systems are provided for carrier selection based on type of packet flow. Service is provided to access terminals on a plurality of carriers in a wireless coverage area. A request is received from a first access terminal. The request indicates that the first access terminal is requesting a packet flow, and the request comprises a packet-flow-type indication. It is determined whether the packet-flow-type indication is associated with an expedited-forwarding quality of service (QoS). If the packet-flow-type indication is associated with an expedited-forwarding QoS, it is further determined that, among the plurality of carriers, a first carrier has the fewest ongoing packet flows having the packet-flow-type indication; responsively, the first access terminal is instructed to conduct the requested packet flow on the first carrier.

Methods and systems are provided for synchronizing reservation status between an access terminal and an access node. In one embodiment, an access terminal receives a report from an access node, the report reflecting a first set of reservations, wherein the first set is a set of reservations that the access node is maintaining with respect to communicating with the access terminal. In response to receiving the report, the access terminal compares the first set of reservations with a second set of reservations, wherein the second set is a set of reservations that the access terminal is maintaining with respect to communicating with the access node. Upon comparing the first set with the second set, the access terminal determines that the first set is not equal to the second set, and responsively sends one or more messages to the access node to cause the access node to modify the first set to match the second set.

Methods and systems are provided for dynamic adjustment of the reverse-link frame-error-rate (RFER) target based on reverse-link RF conditions. In an embodiment, a base station provides service to at least one mobile station on a carrier in a wireless coverage area using a first RFER target. The base station calculates a reverse noise rise (RNR) value for the carrier, and then selects a second RFER target based at least in part on the calculated RNR value. The base station then provides service to at least one mobile station on the carrier in the wireless coverage area using the second RFER target.
