6What is an NSI Phone?
- Every cell phone is unique and must be positively
identified via an electronic handshake with the
wireless switch before service is activated. - An NSI phone is one that has not completed the
handshake, or has failed the handshake. - Discarded (failed)
- Newly purchased (failed)
- Power up (not complete)
- Service lost/restored (not complete)
7Why are NSI Phones Capable of 9-1-1?
- Congressional pressure (Eshoo, D-Ca)
- FCC Mandate
- Similar to warm dial tone for landline
- For 9-1-1 calls, carriers skip the handshake
- The road to hell..
8How do NSI Phones Work?
- Call routing based on cell sector (same as normal
wireless call) - PSAP receives ESRK, but no CBN
- The CBN is typically 911 7 digits of Electronic
Serial Number - Location info is provided (assuming capability of
phone and PSAP) - Accuracy not adequate to pinpoint user (same as
normal Phase 2)
9NSI Phones Are Perfect Harrassment Tools
- No phone numberno CBN, in exact location, not
traceable - Many children find amusement by playing with
their NSI phones - Older users are malicious
- No good deed goes unpunished
10Consequences
- Dispatcher in Chicago, victimized by one too many
prank calls, chastised child for playing with the
phone. The call was legitimate, however, with
tragic results and lawsuits. - Numerous anecdotal reports of false reports of
serious crimes causing responders to kick in the
doors of innocent, sleeping, unsuspecting victims - Intentional misdirection of police away from a
crime in progress.
11Statistics
- Tennessee
- 2 of NSI calls are legit
- Oct-Dec 06 54 different callers dialed 9-1-1
from an NSI phone more than 10 times (max140) - Of these 54 people, 8 were children
12More Statistics
- Florida
- 12-county survey for one month
- 4 of all NSI calls were legit
- Michigan
- 2-month survey
- .05 of 1000 NSI calls were legit (5 calls)
- Washington
- Snohomish County-6 week survey
- 2 of 553 NSI calls were legit
13What is Being Done About NSI Phones?
- FCC has amended the NSI mandate to allow carriers
to block harassment calls - Carriers are reluctant to block calls due to
liability concerns and cost considerations - Who has authority to identify a harasser?
- No existing technology to block specific NSI
calls.
14What is Being Done About NSI Phones?
- Petition to FCC
- NENA, APCO, NASNA, several states
- Petition called for FCC Notice of Inquiry
- FCC Notice of Inquiry (Nov 3, 2003)
- 70 Respondants with various recommendations
- Block all NSI Phones terminate NSI requirement
- Block specific NSI Phones using various
technologies - NENA submitted reply response
15NENA Response to FCC Notice of Inquiry
- Opposed termination of NSI requirement and
supported blocking of individual calls - Called for Advisory Working Group for negotiated
rule making - Identified issues to be resolved
- What technology to be used to block calls?
- How to define a harassment call what triggers
blocking? - Liability
- How long should blocking persist on any one
phone? - Funding/Cost Recovery
16Options
- Terminate all 9-1-1 service for NSI phones (if
the phones dont work for regular calls, why
should there be an expectation for 9-1-1?) - Or,
- Block Harassment Calls from specific phones
17Technology for Blocking Individual NSI Calls
- Block at the PSAP
- Recommended by carriers
- Assuages liability concerns
- Places burden for blocking on the entity that
wants the calls blocked - Does hardware/software exist to block NSI calls?
- Can calls be routed to recording?
18Technology for Blocking Individual NSI Calls
- Block at the MSC/MPC
- Development work required
- How to communicate block order?
- Automated timer on blocks
- Calls can be routed to recording
- Possible call processing delays for all 911 calls
19Potential issues if all NSI wireless handsets are
blocked
- The carrier processing the call may not be able
to distinguish a handset that has no active
account with any carrier from a handset
subscribed to a carrier with whom the carrier
processing the call does not have an automatic
roaming agreement. - A carrier may block a 911 call due to billing
errors or disputes or a simple case of a check
lost in the mail. - Immediately and for several seconds after power
on, MSC to MSC handoff, recovery from loss of
service in a tunnel etc, system "reboots", and
other normal network events a handset will appear
to be non-initialized and be blocked from making
911 calls.
20Potential Issues if we block individual wireless
handsets
- Each suspect handset will have to be blocked on
every carrier with a compatible air interface or
the handset will simply roam to another
compatible network. - Bad actors will simply get another NSI handset at
a yard sale or thrift store. There is a virtually
unlimited supply of such handsets. - Bad actors may donate the blocked handset to a
thrift store which could prevent a decent citizen
from making a 911 call to request help for
someone else who really needs it. - Call processing can be delayed or complicated as
the telephones electronic serial number on every
911 call will have to be compared to a list of
blocked serial numbers. - Because it is extremely difficult, perhaps
impossible, to uniquely identify NSI handsets
even using the ESN of the handset, the wrong
handset may be blocked when attempting to block a
harassing caller or other inappropriate 911
calls.
