Abstract
A mobile device and a method and circuit for determining a position of the mobile device is disclosed. A positioning signal is received at a communication circuit of the mobile device. The received positioning signal is sent from the communication circuit to a position-determining module for determining the position of the mobile device from the positioning signal. A switch may be configured to selectively couple the position-determining module to the communication circuit.
Claims21
A method of determining a position of a mobile device, the method comprising:
- receiving a positioning signal at a circuit of the mobile device, wherein the circuit is configured for wireless two-way communication;
- and
- sending the received positioning signal from the circuit, prior to a communication modem of the circuit, to a multilateration location and monitoring service (M-LMS) module of the mobile device via a switch that selectively couples the circuit to the M-LMS module to determine the position of the mobile device from the positioning signal.
A circuit for determining a position of a mobile communication device, comprising:
- a communication circuit including an antenna and a communication modem, wherein the communication circuit is configured for wireless two-way communication;
- a splitter configured to split a positioning signal received at the antenna prior to the positioning signal being received at the communication modem;
- a multilateration location and monitoring service (M-LMS) module configured to determine the position of the mobile device using the split positioning signal;
- and
- a switch configured to selectively electrically couple the M-LMS module to the communication circuit at the splitter to send the split positioning signal to the M-LMS module.
A mobile communication device, comprising:
- a circuit including an antenna and a communication modem, wherein the circuit is configured for wireless two-way communication;
- a splitter configured to split a positioning signal received at the antenna prior to the positioning signal being received at the communication modem;
- a multilateration location and monitoring service (M-LMS) module configured to determine a position of the mobile device using the split positioning signal;
- and
- a switch configured to electrically couple the M-LMS module to the splitter to direct the split positioning signal to the M-LMS module.
