    摘要： Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry with first and second ports that are coupled by switching circuitry to first and second antennas. A first receiver in the transceiver circuitry may be associated with the first port and a second receiver in the transceiver circuitry may be associated with the second port. An electronic device may be operated in a single receiver mode in which only one of the receivers is active to conserve power or a dual receiver mode in which signals from both antennas may be received in parallel to compare antenna performance. Based on antenna performance metrics, the electronic device may adjust the switching circuitry to ensure that an optimal antenna is being used.

    摘要： A method to control configuration change times is performed at a mobile wireless communication device when the mobile wireless communication device is connected to a wireless network. The mobile wireless device is connected in a first configuration mode. The mobile wireless communication device receives a control message from a radio network subsystem in the wireless network at a local receive time. The received control message includes a time indication for when to start a configuration mode change of the mobile wireless communication device, which the device extracts from the control message. The mobile wireless communication device reconfigures to a second configuration mode, different from the first configuration mode, based on the extracted time indication and the local receive time.

    摘要： Methods and apparatus enabling dynamic and adaptive network selection. In one embodiment of the invention, a device quickly identifies the a subset of networks providing service to a particular location without obtaining and/or prioritizing a full list of all available networks. A “highest” priority network is selected for registration. For example, a mobile device that cannot locate its home (or last registered) network (e.g., Public Land Mobile Network (PLMN)), searches for any available network. The mobile device can identify its current location from information broadcast by any networks (e.g., a Mobile Country Code (MCC)). Once the mobile has identified its current location, it searches for prioritized networks within its current location.

    摘要： A method and apparatus for adapting transmission to improve quality of service in a mobile wireless device that includes an application processor and a transceiver. An application service connection is established between the mobile wireless device and a remote device. The transceiver in the mobile wireless device monitors real time properties of a radio frequency access link that transports packets for the application service between the mobile wireless device and a wireless communication network. The transceiver provides local feedback to the application processor of updated values of the monitored real time properties. The application processor adjusts packet data generation and transmission in response to the updated values to manage quality of service for the application service connection. Packet data transmission adjustment includes active management of queues in the transceiver by the application processor, selectively dropping packets based on packet classifications and the local feedback information provided to the application processor.

    摘要： A system includes a network controller to communicate with a telecommunications network. The network controller is coupled to one or more unlicensed wireless base stations serving one or more unlicensed wireless access areas. Each unlicensed wireless access area is mapped to one or more licensed wireless access areas. The system includes a mobile station to communicate with the telecommunications network using a licensed wireless communication channel serviced by the telecommunications network in a licensed wireless access area, and an unlicensed wireless communication channel in an unlicensed wireless access area. The mobile station is associated with a licensed wireless network identifier and a licensed wireless location identifier when the mobile station is in the licensed wireless access area and is associated with an unlicensed wireless network identifier and an unlicensed wireless location identifier when the mobile station is in the unlicensed wireless access area.
