Talk:ACCOLC

It looks like it is a setting on the SIM card - google is bringing up some phreaking-related stuff but it's hard to identify network and country from them. Secretlondon 8 July 2005 05:52 (UTC)

Is ACCOLC also used for non-emergency congestion? -- Karada 09:00, 13 July 2005 (UTC)

I have no idea. I've only seen it used in reference to emergencies - but network congestion much lower profile I guess. Secretlondon 10:18, 13 July 2005 (UTC)

I would mention the fact that if ACCOLC is invoked, users outside the affected cell can telephone a mobile user in the affected cell. In other words, ACCOLC still allow "incoming" calls from other cells with respect to the invoked cell.

Updated Article - July 2010

I have updated the article today. I work for one of the Mobile operators in the UK on the MTPAS team. ACCOLC is now redundant in the UK, and has been fully replaced by MTPAS. —Preceding unsigned comment added by 90.195.124.221 (talk) 21:19, 5 July 2010 (UTC)

Restricting network access gradually

It looks like there is other gradual mean of implementing the above, the article below is very interesting

A simple trick to quickly double the number of calls in a cell is to use what is known as "half rate coding".

This happened in many central London cells on 7 July and involves compressing the call in a way that allows two calls to be carried in the same bandwidth normally used for one.

It causes some loss of quality but both people will still be able to understand one another.

According to David Sutton, network continuity and restoration manager of operator O2, the system works, but only to a point.

ACCESS OVERLOAD CONTROL 

System allows a network's individual cells to be shut down Decision made by a police 'gold' command or the Cabinet Office Emergency servic

silver?

"...In the UK, the authority of a Police "Silver" is required..." I'm not sure (and it's both POV & OR), but I thinks it's a "Gold" level descision to activate the system. Any sources we could actually use on this?? --RedHillian 02:34, 6 January 2007 (UTC)

Separate MTPAS-specific details out to MTPAS?

It seems this article has a lot of information on how MTPAS works, when that information should really go onto the MTPAS page. As I don't know how the systems work, I don't know enough to know if this really is MTPAS being described in the page, so I just wanted to raise this point and let people who know more about it than I do handle it! --TheSophera (talk) 12:46, 2 September 2011 (UTC)
