摘要： A method and apparatus to improve the robustness of a wireless communication link between a base station and a mobile communication device. The method increases power selectively on portions of an uplink communication signal transmitted from the mobile communication device to the base station. The method monitors a quality metric value at the mobile communication device and sets the transmit power level of the first portion of an uplink communication signal to the first power level, if the monitored quality metric value is in a first range of quality values, or sets the transmit power level of the first portion of the uplink communication signal to a second power level, if the monitored quality metric value is in a second range of quality values. The first portion of the uplink communication signal includes control signals used by a base station to maintain connection of the wireless communication link.

摘要： User equipment such as cellular telephones and other wireless electronic devices may communicate wirelessly with 2G and 3G cells in a cellular network. The cellular network may broadcast a list of primary scrambling codes corresponding to 3G cell sites that are potentially available for wirelessly communicating with the user equipment. The user equipment may perform an evaluation of primary scrambling code pilot signal strengths for each of the primary scrambling codes in the list. The user equipment may also maintain a record whenever a more extensive full primary scrambling code scan fails. If the evaluation reveals that at least one signal strength is sufficient, the cellular telephone may establish a corresponding 3G wireless link. If the evaluation does not identify any sufficiently strong 3G cells, a full pilot signal scan may be performed, provided that no full scans have failed within a predetermined time interval before the current time.

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 for minimizing scheduling collisions between networks. In one embodiment, the networks are substantially unsynchronized, and during hybrid network operation (e.g., LTE and CDMA 1× operation), a mobile device can place CDMA 1× voice calls while registered with the LTE network. However, since the LTE and CDMA 1× networks are not coordinated, the mobile device will experience scheduling collisions. In one variant, the LTE network accounts for predictable behaviors (such as CDMA 1× paging), and schedules low priority tasks during likely time interval conflicts. Consequently, even though the mobile device must tune away from the LTE network to check CDMA 1× pages, overall LTE network performance is minimally affected.

摘要： Maintaining communication of a wireless device and using a plurality of wireless communication technologies. A first paging message schedule may be determined for maintaining communication between the wireless device and a first base station associated with a first wireless communication technology. Similarly, a second paging message schedule may be determined for maintaining communication between the wireless device and a second base station associated with a second wireless technology. Additionally, a scheduling conflict may be determined between the first paging message schedule and the second paging message schedule. Accordingly, communication with the first base station may be switched to a third base station using the first wireless technology in response to determining that there is a scheduling conflict.
