摘要： An electronic device may contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. The electronic device may use the multiple antennas to make received signal power measurements. The signal power measurements may be made for each frequency in a list of frequencies used most recently by the electronic device in conveying data traffic between the electronic device and a wireless network. Based on received signal power measurements, the electronic device may select which frequency to use in performing system acquisition operations to attempt to establish a wireless communications link between the electronic device and the wireless network. The device may make signal power measurements for each antenna in the device to determine which antenna should be used in performing the system acquisition operations or may rotate through antennas in sequence to identify an antenna that can successfully perform system acquisition operations.

摘要： Conserving battery by a wireless user equipment (UE) device in substantially stationary conditions. A first wireless link may be established with a first cell. It may be determined that the UE device is substantially stationary. One or more signal strength and/or signal quality metrics associated with the first wireless link may be measured. The one or more signal strength and/or signal quality metrics may be below a first threshold. The UE may ordinarily be configured to perform a search for neighboring cells if the one or more signal strength and/or signal quality metrics are below the first threshold. The UE may not actually perform a search for neighboring cells, based on determining that the UE is substantially stationary.

摘要： A method to control multiple radio access bearers is performed at a mobile wireless communication device when the mobile wireless communication device is connected to a radio network subsystem in a wireless communication network by first and second bidirectional radio access bearers. The mobile wireless communication device transmits a data packet on an uplink of the first bidirectional radio access bearer to the radio network subsystem. When the data packet is not correctly received by the radio network subsystem, the mobile wireless communication device retransmits the data packet repeatedly. After N retransmissions of the data packet, the mobile wireless communication device releases the first bidirectional radio access bearer while maintaining the second bidirectional radio access bearer. The first bidirectional radio access bearer provides a channel to transport packet switched data, and the second bidirectional radio access bearer provides a channel to transport circuit switched data.

摘要： Establishing a circuit-switched fallback (CSFB) call. A request to establish a CSFB call may be received. A first wireless link with a first cell may be released. The first cell may provide packet-switched services but not circuit-switched services. A second wireless link may be established with a second cell. The second cell may provide packet-switched services and circuit-switched services. The CSFB call may be established via the connection to the second cell. Packet-switched registration with the second cell may be performed after the CSFB call is established.
