Abstract: Method, apparatus and computer program product measuring signals received through multiple antennas in a mobile wireless device is described. Signals received through at least one of a primary antenna and a secondary antenna, during each cycle in a series of discontinuous reception cycles, is measured. The mobile wireless device switches between the primary and secondary antennas based on comparing the moving averages of the measured received signals to pre-determined thresholds. When unable to decode successfully a signal received on the primary antenna, the mobile wireless device switches to decode signals received on the secondary antenna.

Abstract: 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.

Abstract: 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.

Abstract: 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.
