04 | Keysight | E6965A Location Server Emulator - Technical Overview

Keysight offers additional components to facilitate testing of SUPL-enabled terminals.

The Keysight 8960 Wireless Communications Test Set, with appropriate Lab Application,

is used as the cellular base-station emulator. A Keysight ESG Vector Signal Generator

may be used as a GPS satellite simulator. The E6965A is also capable of operating with

alternative GPS satellite simulators, as long as assistance data for the GPS scenarios is

known and available to the E6965A using a .csv file format.

E6965A Capability

The location server emulator includes:

– SUPL Location Platform (SLP) emulator

– LCS Positioning Server emulator

– Bootstrapping Server Function (BSF)

– Automated RRC and RRLP positioning message encoding/decoding

– Server logging tool (decrypted messages)

The location server emulator supports:

– SUPL v1.0 network-initiated and SET-initiated SUPL sessions

– Proxy flows for 2G GSM/GPRS/EGPRS and 3G W-CDMA / HSPA

– SET-based and SET-assisted A-GPS and Autonomous GPS positioning

– Authentication using PSK-TLS, 3GPP GBA, TLS and certificate

– Test automation through SCPI interface
