OMA LPP Extensions (LPPe) V1.0Background / Relationship to LTE Positioning Protocol (LPP)
3GPP RAN2 Working Group (WG) has defined LTE Positioning Protocol (LPP) - positioning protocol for E-UTRAN
Operates on a transaction basis between a target device and a server
Transaction Types Exchange of positioning capabilities
Transfer of assistance data
Transfer of location information(positioning measurementsand/or position estimate)
Target Device Server
3GPP Evolved

Also: LPP Abort, LPP Error
8
OMA LPP Extensions (LPPe) V1.0
LPP specifications extensible by other fora (outside
3GPP)
OMA LPP Extensions (LPPe) specifications extend
the LPP capabilities for User Plane needs
No new messages – 3GPP LPP messages extended
New positioning methods and procedures
Benefits of OMA LPP Extensions (LPPe) reuse of
3GPP-defined LPP:
Convergence of control and user plane positioning
protocols
Reduced work load
Ability to use the same LPPe protocol in both the
control and user planes
9
OMA LPP Extensions (LPPe) V1.0Key Features
High accuracy satellite positioning
Extends the set of cellular network positioning methods
Enhanced Cell ID, Time-Difference-of-Arrival (TDOA)
Indoor positioning technologies
WLAN
Short-range radio nodes (e.g., Bluetooth)
Sensor support
Assistance data segmentation
Supports sending large amount of positioning assistance information from the server to the terminal
Extends directionality of LPPe messages
LPP Mode qualifies the server and target roles

Out-of-scope for LOCSIP
e.g., Secure User Plane
Location (SUPL)
Location in SIP/IP core (LOCSIP) High-Level Architecture
LOCSIP specifies how to use Session Initiation Protocol
(SIP) to obtain location information
Messaging is based
on SIP SUBSCRIBE /
NOTIFY procedures
Location Client - Functional entity
that subscribes to a Location Server
in order to obtain location information
for one or more Targets.
Location Server - Functional entity
that handles location service
subscription request and retrieves the
location information of the Target.
Target - The device or the
user associated with a device
whose location is requested.
13
Location in SIP/IP core (LOCSIP) Capabilities
LOCSIP allows an application to obtain location information in a SIP/IP core network (e.g., an IP Multimedia Subsystem [IMS])
Reuses capabilities in a SIP/IP core network (e.g., security associations, Application Servers) for receiving and responding to location subscriptions over a standardised SIP-based interface
Synergy with other OMA enablers that potentially use location information (e.g., Presence SIMPLE and PoC)
Reuse available IETF specifications (e.g., IETF Geopriv deliverables)
Rich set of capabilities include:
Support for “Immediate”, “Periodic” and “Area Trigger” Location Delivery
Support filtering of location notifications (accuracy, response time, age)
Support for Location Client in a SIP Application Server or in a terminal.
Location Client able to request location information for a group of Targets, based on referenced list or request-contained list
Support Geographic or Civic location information format
