scope:

This document addresses integration of an uplink TDOA positioning technology as a remote PDE operating within a GERAN complex as defined in 3GPP Release 6.0. This integration constitutes vendor implementation details of a Location System. 3GPP standards for LCS identify such details as are presented here as being outside the scope of the 3GPP standards. The purpose here, then, is to provide a full description of implementation of a remote PDE such as might be employed in support of an LCS client such as an emergency services (ES) public services access point (PSAP)

The Lbis interface is applicable to North American GSM networks using UTDOA in support of E911 Phase 2 emergency services. The interfaces, protocols, and methods described here are potentially applicable to the integration of other remote PDEs to GERAN and/or UTRAN complexes.
