Apparatus, system and method for determining a geographical location of a portable communication device
First Claim
1. A position determining entity (PDE) for determining a geographical position of a wireless communication device capable of communicating within at least a wireless wide area network (WWAN), the PDE comprising:
- a processor configured to determine the geographical position based on wireless local area network (WLAN) location information related to a WWAN reverse link (RL) signal received from the wireless communication device at an access point of a wireless local area network (WLAN).

Abstract
A wireless access point receives a reverse link (RL) wireless wide area network (WWAN) signals from a wireless communication device and forwards wireless local area network (WLAN) location information related to the received RL WWAN signal to a position determining entity (PDE). The PDE uses the WLAN location information and, in some cases, other location information to determine the geographical location of the wireless communication device. The WLAN location information is any information that at least assists the PDE in determining the geographical location of the wireless communication device and may include any combination of data related to signal strength of the WWAN RL signal, a propagation time of WWAN RL signal, a distance between the access point and the wireless access point, a geographical location of the access point, and/or a geographical location of the wireless communication device.
