Abstract: In systems and methods for managing call admission, a channel request comprising a first service level priority is received from a first wireless device at an access node. Channels of the access node associated with a second service level priority greater than or equal to the first service level priority are selected. A loading of the selected channels is determined, and the loading of the selected channels is compared to a loading criteria. When the determined loading meets the loading criteria, a preemption attempt is performed of a channel associated with a third service level priority less than the first service level priority.

Abstract: A method and system is disclosed for coordinating codec assignment and radio configuration in wireless communication sessions. When a communication session is set up for an access terminal (AT) operating in a wireless communication system, a network device, such a base station, can determine a coding rate to assign the AT for its air interface in a manner that accounts for radio configuration in a wireless coverage zone of the base station. The base station could use a distribution of types of cover codes in use to monitor radio configuration, and then assign a codec and coding rate for new calls based on the distribution.

Abstract: In a shared communication service plan in which multiple subscribers operate under a common billing account, a method and system is provided for more equitably allocating service costs among the subscribers in the group, by allocating overage costs based on the extent to which each subscriber used base services available to the group. For instance, if the group plan includes a designated number of base minutes of service per month and defines a per-minute overage cost for minutes used beyond the base number, the method and system may allocate to a given subscriber a portion of the group's overage cost, with the portion being determined based on the portion of the group's base minutes used by the subscriber. Advantageously, an invoice may then be generated setting forth the equitable allocation among the subscribers in the group, thus allowing the group to more readily determine how much each subscriber should pay.

Abstract: A plurality of frequencies are generated at a wireless device and a frequency which a user perceives as the loudest frequency is determined. A first frequency range is selected comprising a first minimum frequency and a first maximum frequency. A ringtone is processed to shift the second frequency range to within the first frequency range, wherein an average frequency of the processed ringtone is the determined loudest frequency.

Abstract: A user, identified by a network access identifier (NAI) or other user identifier, uses a communication device, identified by a hostname or other device identifier. An Internet Protocol (IP) address is obtained for the communication device, e.g., when the user logs in for access to a packet-switched network. An association between the IP address and the hostname is registered in a domain name server. An association between the user identifier and the hostname is registered in an RWHOIS server. An application may query the RWHOIS server to determine the hostname of the communication device being used by the user and then query the domain name server to determine the IP address of the communication device.

Abstract: 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.

Abstract: An address assignment device may support assigning either a public address or a private address to a client device. In order to increase the number of client devices that can share a public address via network address translation, the client device may be assigned a public address when the client device's expected port utilization is at or above a port utilization threshold. However, the client device may be assigned a private address when the client device's expected port utilization is below the port utilization threshold.

Abstract: While a first and second entity are engaging in a communication session on a wireless link, the first entity may be sending a series of power control commands (PCCs) directed to the second entity at a first transmission rate. Additionally, the first entity may monitor an actual and expected transmission-power adjustment of the second entity. Based on this monitored actual and expected transmission-power adjustment, the first entity may decide to alter the PCC transmission scheme for the second entity. For instance, if the monitored actual and expected transmission-power adjustment differs by a threshold extent, the power-controlling entity may decide to increase the PCC transmission rate for the power-controlled entity and/or increase the transmission-power adjustment instructed by PCCs directed to the second entity. In response, the first entity may begin sending the series of PCCs directed to the second entity according to the altered PCC transmission scheme.

Abstract: A mobile station receives system time information from a source base transceiver station (BTS) in a spread spectrum communication system. The mobile station estimates a distance between the mobile station and the source BTS. The mobile station calculates a propagation delay based on the estimated distance. The mobile station develops a propagation-delay-adjusted time reference based on the system time information and the calculated propagation delay. The mobile station uses the propagation-delay-adjusted time reference to search for a target pseudonoise (PN) offset corresponding to a target BTS in the spread spectrum communication system. The mobile station may be closer to the target BTS than the source BTS.

Abstract: A wireless communication device (WCD) that is configured to originate and receive push-to-talk (PTT) calls may be identified by a standard identifier in standard PTT calls and may be identified by an emergency identifier in emergency PTT calls. The WCD may be configured to recognize an emergency trigger and, in response to the emergency trigger, originate an outgoing emergency PTT call, using the emergency identifier. If, while engaged in a standard PTT call, the WCD receives an incoming emergency PTT call that includes the WCD's emergency identifier, the emergency PTT call may preempt the standard PTT call. For example, the WCD may convey audio from the emergency PTT call to a speaker or other audio output interface, instead of audio from the standard PTT call. The WCD may also release the standard PTT call.
