ATIS 0700002

This Technical Report descrives how the UTDOA position determination system for locating mobile stations may be applied to GSM networks in a manner consistent with 3GPP and other relevant standards. UTDOA (uplink time difference of arrival) is one of the location technologies identified in the 3GPP GSM standards. The Lbis interface and Remote PDE Protocol (RPP) enable upgrading earlier proprietary implementations of UTDOA to a standards-based solution with minimal impact to the network infrastructure.
