OMA LPP Extensions (LPPe) V1.0
3GPP LPP is a positioning protocol that provides procedures for
- Request and Provision of location information including raw measurements
- Request and Provision of assistance data
- Request and Provision of capabilities
OMA LPP Extensions (LPPe) build on the 3GPP-defined LPP and extends the location, measurement and assistance data capabilities beyond 3GPP LPP without unnecessarily duplicating the work done in 3GPP.
The OMA LPPe Release 1.0 enables support for
- High accuracy GNSS methods in the form of new positioning methods and assistance data types
- Emerging radio network –based positioning technologies including the radio network measurement reports for selected radio access types
- Terminal-to-terminal positioning and assistance data transfer
Moreover, OMA LPPe attempts to be bearer-independent as far as possible with respect to non-bearer associated position methods like A-GNSS and any terrestrial method applicable to a non-serving network.
Security, authentication, privacy and charging are out of scope of LPPe. It is assumed that these services are provided by the user plane protocol which uses LPP/LPPe as the positioning protocol.
