  • Patent number: 8351953
    Abstract: In a wireless communication system, a wireless access node provides a wireless communication service to wireless communication devices over a first frequency band class and over a second frequency band class. A control system identifies a subset of the wireless communication devices operating over the first frequency band class that have been in an idle mode for a time period that exceeds a threshold. The wireless access node transfers a signal to the subset of the wireless communication devices to transition from the first frequency band class to the second frequency band class. The wireless access node then provides the wireless communication service to at least some of the subset of the wireless communication devices over the second frequency band class.

  • Patent number: 8305994
    Abstract: Systems, computer-readable storage media, and methods are disclosed for providing wireless voice communication transmissions between a mobile unit and at least one base station. An illustrative method may comprise receiving an access request from a mobile unit. Based on information extracted form the access request and protocols for selecting a communication channel, identifying a selected communication channel for transmissions between the mobile unit and the base station. In the event of congestion or poor RF quality on the selected communication channel, where multiple communication channels associated with a home network are available at a base station, the mobile unit will attempt to access an alternate communication channel before going to a roaming network.

  • Patent number: 8305976
    Abstract: What is disclosed is a method of operating a wireless communication device. The method includes, when in a first mode of operation, transmitting an access request to a wireless access node at a first transmit power, starting a first countdown timer, and awaiting an access request acknowledge from the wireless access node. In the first mode of operation, if the access request acknowledge is received within the first countdown timer, the method includes halting the first countdown timer and awaiting a resource assignment message from the wireless access node, and if the access request acknowledge is not received within the first countdown timer, the method includes retransmitting the access request to the wireless access node at a second transmit power and restarting the first countdown timer.

  • Patent number: 8270966
    Abstract: A method, system, and computer-readable media are provided for reducing mobile device roaming. A set of transition mobile-network attributes are captured by an idle mobile device before switching from a roaming network to a home network. A collection of transition mobile-network attributes are used to generate transition-based data. Active mobile-network attributes are compared to the transition-based data and used to recognize when the mobile device is within an area that can receive one or more services from the home network.

  • Patent number: 8264978
    Abstract: Various systems and methods are provided to manage and operate a wireless communication system. A processing system receives an application data flow from a wireless device located in a sector of a base station. The application data flow comprises a plurality of data packets. At least one of the data packets is inspected for an attribute. Also, an application data flow characteristic is measured for the application data flow. The processing system evaluates the attribute and the application data flow characteristic against a network policy associated with the wireless device. When the attribute and the application data flow characteristic meet the network policy, the processing system provides a wireless communication adjustment notification to the base station.

  • Patent number: 8265645
    Abstract: In a communication system, a wireless access node receives an access request from a wireless communication device. In response, the access node starts an access timer and transfers signaling to the communication system indicating the access request. If the access timer expires before a response to the signaling is received, then the access node provides the wireless communication device with wireless access to the communication system. The access node receives the response to the signaling. If the response is negative and is received before the access timer expires, then the access node denies the access request. If the response is negative and is received after the access timer expires, then the access node terminates the wireless access to the communication system for the wireless communication device.

  • Patent number: 8264966
    Abstract: An RF communication system comprises RF circuitry, access circuitry, and control circuitry. The RF circuitry receives reverse packets from users over reverse RF links. The access circuitry is operationally coupled to the RF circuitry and transfers the reverse packets over a reverse network link. The control circuitry is operationally coupled to the access circuitry and inhibits the transfer of a set of the reverse packets over the reverse network link in response to a reverse overload condition on the reverse network link. The inhibited set of the reverse packets are from the users having a lowest level of reverse packet loss on the reverse RF links.

  • Patent number: 8254406
    Abstract: What is disclosed is a method of operating a wireless access node which exchanges overhead information with user devices in a series of repeating overhead time cycles each comprising a multi-user message and single-user messages. The method includes transmitting the multi-user messages for receipt and use by all of the user devices and transmitting the single-user messages for receipt and use by individual ones of the user devices. The method includes, in response to the single-user messages, receiving acknowledge messages comprising RF condition indicators for the single-user messages. The method includes, if any of the RF condition indicators are below a performance threshold, then suspending further transmission of the multi-user messages in the series of repeating overhead time cycles, and if none of the RF condition indicators are below the performance threshold, then continuing further transmission of the multi-user messages in the series of repeating overhead time cycles.

  • Patent number: 8213358
    Abstract: An embodiment of the current invention is directed to a method of reducing the latency associated with communicating data to a mobile device. It is determined that a threshold period of time has elapsed since a mobile device has communicated a location-determining message. A request for the mobile device to transition to a quick-paging recognition mode is sent to a mobile device configured to perform a process. The process includes: sending a response to the first request as a location-determining message; transitioning to a quick-page recognition mode; receiving an indication to receive a paging-channel message; acquiring the paging-channel message; and returning to the quick-page recognition mode.

  • Patent number: 8131283
    Abstract: Systems, methods, and computer-readable media for controlling roaming of a mobile device when the mobile device is in an active mode while utilizing a roaming network. A duration of an active event for which the mobile phone utilizes the roaming network is referenced. It is determined whether the duration of the active event exceeds an event threshold. The event threshold indicates a maximum amount of time the mobile device is allowed to connect to the roaming network in association with the active event. In instances that the duration of the active event exceeds the event threshold, the mobile device is transferred from the roaming network to a home network of the mobile device.
