A wireless communication system useful in assisting and locating users of mobile communication units (MUs) with emergency situations. In one embodiment, the system includes position determining equipment (PDE) to generate position data information related to receiving an emergency call request, wherein some of the PDEs are associated with a first wireless carrier and others associated with a second carrier; and a mobile positioning center (MPC) adapted to determine an approximate location of an emergency-calling MU from the position data information received from the PDEs. In another embodiment, the system includes PDEs, wherein at least one is a standalone PDE; and an MPC. In another embodiment, the system includes a mobile switching center (MSC), bases stations restricted to emergency use only, and PDEs associated respectively with the base stations. In another embodiment, the system includes PDEs adapted to transmit position data information to an MPC via a wireless medium.
