Warrant requirement to use the Home Location Registry (HLR) for Polling Data
From: M B
Dear New Zealand Police,
In the Telecommunication investigations Manual, a Polling Information Request, through a Comms Centre Polling request, is stated to be sent to the Network Operations Centre (NOC) of the three telcos.
It is described as relating to a "single" polling request. "A query is done on the Home
Location Register (HLR) which is a record of only the last tower a phone polled off. ... There are no historic records and it is constantly overwritten ... . It is not possible to continually ‘track’ from this system as it requires constant manual queries."
1. Please provide the full Telecommunication investigations chapter.
2. Do the New Zealand Police have the access to conduct "manual queries" themselves, or are these relayed to the Telco providers.
3. Is it practically possible to conduct several consecutive manual queries or are there safeguards in place to prevent this? You state that it is not possible to "continually track", but is there anything preventing a bombardment of manual queries as suggested?
4. What is the Warrant / Production Order requirement for single polling requests?
