Abstract: A mobile terminal generates an estimate of GPS time. The mobile terminal includes a cellular receiver, a GPS receiver, and a processor. The cellular receiver is configured to receive communication signals from cells in a wireless communication system. The GPS receiver receives GPS signals and determines a GPS time reference therefrom. The processor estimates a cell time reference from the received communication signals, and generates cell-to-GPS timing data that represents a time offset between the cell time reference and the GPS time reference. The processor then estimates GPS time based on a time indicator portion of a received communication signal and the cell-to-GPS timing data. The estimated GPS time may be used by the GPS receiver to acquire GPS signals.

Abstract: Techniques for reducing interference on radio frequencies due to processor frequencies which control a processor in wireless device are disclosed. A method for reducing interference on radio frequencies includes the steps of determining at least one radio frequency used in the wireless device and assigning an interference factor to a potential processor frequency corresponding to at least one radio frequency used in the wireless device. The method further includes the step of selecting a first processor frequency other than the potential processor frequency to avoid interference with the at least one radio frequency.

Abstract: A mobile device integrates a wireless headset with the housing of a mobile terminal. In an exemplary embodiment, the housing of the mobile terminal includes a fastener for mechanically connecting the wireless headset to the housing. When the wireless headset is mechanically disconnected from the housing, a speaker and microphone associated with the wireless headset interfaces with the mobile terminal via a wireless interface. However, when the wireless headset mechanically connects to the housing, the speaker and microphone associated with the wireless headset mechanically and electrically connect to the housing and operate as the speaker and microphone for the mobile terminal. A detector circuit included in the mobile device also determines the position of the wireless headset relative to the mobile terminal, and may automatically select a wireless or electrical interface between the wireless headset and the mobile terminal based on the determined position.
