The Spirent SMLC Emulator (SSE) is an integrated component of the ULTS system that

allows full control of all assistance data provided to a mobile device during automated

A-GPS testing. The SSE simulates the core functionality of an actual SMLC, allowing for a mobile device to request and receive assistance data through standard 3GPP signaling.

By default, SMLC communication logging is disabled, so you would not see detailed SMLC logging in the default folder: C:\Program Files\Spirent Communications\Spirent SMLC Emulator\EventLog, if further SMLC event log need to be checking, you should config as below:

1, Open fileULTSLogConfig.log4net  under C:\Program Files\Spirent Communications\TestDrive ULTS\ as txt format.

2, Change 4^th line <level value="OFF" /> to <level value="ALL" /> as below:

<?xml version="1.0" encoding="utf-8" ?>

<log4net>

3, Save the file and reopen TestDrive ULTS, after running required test cases, you will get SMLC log under C:\Program Files\Spirent Communications\Spirent SMLC Emulator\EventLog
