Abstract:
A method for requesting location information, for example, Enhanced Observed Time of Arrival timing information, from mobile wireless communications in wireless communications networks. The exemplary location request (300) includes multiple response interval field (310) specifying intervals at which multiple responses to the location request must be sent or maximum intervals between which multiple responses to the location request must be sent, a final response time field (320) specifying a maximum time interval during which a final response to the location request must be sent, and an initial response time field (330) specifying when an initial response to the location request must be sent.
Abstract:
A method and apparatus is provided for power conservation of a hardware module (142) which is coupleable to a portable electronic device (100). The hardware module (142) has unique identification information associated therewith and stored therein. The unique identification information is provided periodically (308) to the portable electronic device (100) and stored therein (207). To conserve power, the portable electronic device (100) sends a power-down notice (212) to the hardware module (142), the module controller (144) stores current state information of the hardware module (142) in a non-volatile memory (146) thereof, and the hardware module (142) is powered off (214).
