20110319081 | FAST CELL SELECTION IN A MOBILE WIRELESS DEVICE - A method and apparatus for fast cell selection by a mobile wireless device. The mobile wireless device detects when a first wireless cell fails a set of stored suitability criteria and searches for and locates a set of candidate wireless cells to associate with. The mobile wireless device measures at least one received signal metric for each candidate wireless cell in the set of candidate wireless cells. When a candidate cell in the set of candidate wireless cells is identically the first wireless cell, the mobile wireless device evaluates the suitability of the candidate wireless cell using the stored set of suitability criteria for the first wireless cell and the measured at least one received signal metric for the candidate wireless cell. The mobile wireless communication device associates with the candidate wireless cell when the candidate wireless cell meets the stored set of suitability criteria. | 12-29-2011 |
20110320856 | METHOD AND APPARATUS FOR SELECTIVE READING OF SYSTEM INFORMATION IN A MOBILE WIRELESS DEVICE - A method to read selectively system information messages in a mobile wireless communication device. The mobile wireless device receives a first transmission of a multiple segment message through a radio frequency receiver. The mobile wireless device detects decoding errors in at least one of the received segments of the first transmission. In response to detecting decoding errors, the mobile wireless device selectively receives a first subset of segments in a second transmission of the multiple segment message. The mobile wireless device powers down at least a portion of the radio frequency receiver during receive time intervals for a second subset of segments in the second transmission. The first subset of segments in the second transmission corresponds to segments in the first transmission received with decoding errors. The second subset of segments in the second transmission corresponds to segments in the first transmission received without decoding errors. | 12-29-2011 |
20120083264 | METHOD AND APPARATUS FOR TRANSPORT FORMAT SELECTION IN A MOBILE WIRELESS DEVICE - A method and apparatus for transport format selection in a mobile wireless communication device. During a simultaneous voice and data call, the mobile wireless communication device selects a transport format for proper uplink data transmission. Simultaneous voice and data calls require higher uplink transmit power than voice only calls. The mobile wireless communication device selects a transport format based on the uplink transmit power level. At higher transmit power levels, minimum or zero data rates are chosen to maintain sufficient power for simultaneous voice. Transmit format is specified using a transmit format combination indicator. | 04-05-2012 |
20120176963 | VOICE AND DATA CONNECTION CONTROL IN A MOBILE DEVICE - Controlling non-simultaneous voice and data connections between a mobile wireless device and a wireless network is described. Following a voice connection origination failure between the mobile wireless device and the wireless network, the mobile wireless device sends a voice connection redial request only after closing an existing data connection between the mobile wireless device and the wireless network. The mobile wireless device tunes a wireless transceiver to a second voice connection channel radio frequency that differs from a first data connection channel radio frequency and establishes a voice connection with the wireless network on the second voice connection channel radio frequency. | 07-12-2012 |
20120178438 | CONTROL OF MEASUREMENT MESSAGING IN A MOBILE DEVICE - A method to control measurement messaging is performed at a mobile wireless device. The mobile wireless device transmits a first measurement message to a radio access network in a wireless network and stores the first measurement message pending receipt of an acknowledgement from the radio access network. Before receiving the acknowledgement to the first measurement message, the mobile wireless device determines at least one parameter included in the first measurement message requires updating. The mobile wireless device deletes the stored pending first measurement message and transmits a second measurement message to the radio access network including an updated value for the at least one parameter in the first measurement message. | 07-12-2012 |
20120178439 | RADIO RESOURCE MANAGEMENT IN A MOBILE DEVICE - Managing radio resources between a mobile device and a wireless network includes at least the following. An application processor in the mobile device classifies radio resources available into at least two distinct sets, a first set of active connections and a second set of potential connections. The application processor forms a measurement message that includes information about the measured radio resources and communicates the measurement message to a wireless network through a transceiver. Before receiving an acknowledgement of the measurement message from a radio network subsystem in the wireless network, the application processor determines at least one parameter included in the measurement message requires updating. The transceiver stops transmitting the measurement message in response to commands from the application processor. | 07-12-2012 |
20140119219 | CONTROL OF MEASUREMENT MESSAGING IN A MOBILE DEVICE - A method to control measurement messaging is performed at a mobile wireless device. The mobile wireless device transmits a first measurement message to a radio access network in a wireless network and stores the first measurement message pending receipt of an acknowledgement from the radio access network. Before receiving the acknowledgement to the first measurement message, the mobile wireless device determines at least one parameter included in the first measurement message requires updating. The mobile wireless device deletes the stored pending first measurement message and transmits a second measurement message to the radio access network including an updated value for the at least one parameter in the first measurement message. | 05-01-2014 |
