[AusNOG] Telstra Mobile network bad time zone settings - Brisbane CBD

[derek at madrock.net]

Hi Bruce,

 

To add to the risk, I was involved in a parliamentary enquiry in NZ when working for EY, where customers were being charged extra for calls based on call ticketing inaccuracies, resulting from non-synchronised cells.

 

Other than being very embarrassing for the carrier, it was expensive as they were required to correct the over and under customer payments.

When I was reviewing it, I found older nodes were using a centralised Perl scripts to periodically log into and reset the time, where newer devices were using NTP.

*	The issues was discovered to be a range of things including the centralised Perl script not being able to log into the node (wrong passwords), new nodes not registered centrally when deployed and NTP not configured.
*	Times varied depending on the node drift and if the technician setup old/new nodes properly when deployed.
*	Call ticketing handover when roaming between nodes also negatively contributed to the evidence needed to reconcile billing when syncing issues exist.

 

Just a related point. Good luck with getting it sorted.

 

 

Thanks

Derek

Hi noggers,

 

Hoping someone @ telstra is on the list who can take a look at this one.

 

You have a radio near central station in Brisbane, approx 180 ann st area that is giving off bad time zone data, my phone switched from +10 to +8 and when i walked back to the office again back to +10..

 

I'm based at 300 ann. If you need more data about it please feel free to contact me off list.

These were taken at 11:48pm, and 12:20pm 2nd Oct 2019, 

 

Sorry if there is a page on telstra's site to report this but i guess my google fu was bad this time.

Bruce
