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： Methods and apparatus enabling a mobile device to receive paging notifications from multiple networks. In one embodiment of the present invention, a first device connected to a first network momentarily ignores the first network, to monitor a second network instead. The first device identifies and prioritizes a list of applications of the first network; the prioritized listing allows the first device to preempt one of its lower priority tasks to monitor the second network for paging messages instead. The described methods and apparatus enable e.g., GSM paging for Class B cellular devices which are connected to GPRS NMO-2 type networks. The Class B cellular device can ignore certain GPRS data (which is tolerant to error), to decode GSM paging channels, which would otherwise be missed.

摘要： Methods and apparatus for resolving frequency errors in a wireless device transitioning from a first communication network to a second communication network are disclosed. The methods and apparatus effect reception of a first and second channels from the second communication network where the first channel has known characteristics. The first channel is then decoding for a prescribed period and an initial frequency error value is determined based on the decoding of the first channel. A digital frequency rotator is then adjusted based on the initial frequency error value for purposes of decoding the second channel. The second channel is then decoded using the digital frequency rotator as adjusted based on the initial frequency error value, without further calculation of the frequency error.

摘要： A terminal obtains a monitored set containing GSM neighbor cells and/or UMTS neighbor cells. The terminal operates in a compressed mode and obtains from a UMTS network at least two transmission gap pattern sequences for different measurement purposes, e.g., for “GSM carrier RSSI measurements” (GAP1), “GSM initial BSIC identification” (GAP2), and “GSM BSIC re-confirmation” (GAP3). The terminal makes RSSI measurements for the GSM cells using multiple transmission gap pattern sequences, e.g., using GAP1, GAP2 and GAP3. The terminal identifies the BSIC for at least one GSM cell by (1) detecting the tone on the FCCH using multiple transmission gap pattern sequences, e.g., using GAP2 and GAP3, and (2) decoding the SCH using multiple transmission gap pattern sequences, e.g., using GAP2 and GAP3. The use of multiple transmission gap pattern sequences for RSSI measurement and BSIC identification allows the terminal to complete the cell measurements and send a report sooner, which may improve performance.
