1. 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.

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.
