ACCOLC

ACCOLC (Access Overload Control) was a process in the United Kingdom for limiting mobile telephone use in times of emergencies. It is like the GTPS (Government Telephone Preference Scheme) for landlines.

This process allowed the telephone networks to limit access in a specific area to registered numbers only and is normally started by the Police Incident Commander (although it can be invoked by the Cabinet Office). The emergency services are responsible for registering their key numbers in advance.

ACCOLC was replaced by MTPAS (Mobile Telecommunication Privileged Access Scheme) in 2009.^[1]

Use

ACCOLC was deployed at the Hillsborough disaster.^[2]
