Inside the Journey of a 911 Call

When an emergency strikes, you pick up the phone and call 911. A helpful call taker confirms your address, gets the details of the emergency, and help arrives within minutes. Sounds simple, right?

If you’re dialing 911 from your office, a hotel or a remotely connected softphone, that simple interaction may actually be a pretty complex transaction. It requires multiple systems to integrate and communicate to get you the help you need. West supports the journey of a 911 call from start to finish. Read on to find out what happens behind the scenes and learn about the technologies that enable enterprise 911.

Q&A: The Revolution of Wireless 911 Location Technologies

By John Snapp, VP of Technology

Earlier this month, I presented to carriers and PSAPs about new solutions that promise a better location earlier in the 9-1-1 call flow. I also spoke about the methodology and results from West’s location testing and trials with Google’s Android-based ELS (handset-initiated location).

The following addresses the questions I wasn’t able to respond to during the live event.

Q: We received many similar questions around the timing and availability of the wireless 9-1-1 location technologies discussed. Many asked, when will these solutions be made available? How soon will PSAPs start to benefit from the improved location? What are the potential implementation impacts to carriers and PSAPs?

The Top Three E911 Obstacles Facing Enterprises

When we talk to enterprises about 911, we often hear about the E911 obstacles they face to making sure they can provide appropriate support to their users in a crisis. From roadblocks around awareness, to cost concerns, to management burden, the top three obstacles to enterprise 911 arise again and again in our conversations. Fortunately, enterprises can overcome these obstacles.

E911 Obstacle 1: Not Knowing that E911 is Broken

Perhaps the first obstacle enterprises face when it comes to 911, is knowing that they have a problem to begin with. When embarking on a transition to Unified Communications (UC), or implementing softphones, or adding another UC system to the mix, there are literally thousands of factors your IT team is considering. It’s easy to lose 911 in the shuffle.

What is E911 and Why Should My Enterprise Care?

Enhanced 911, or E911, is a technology that allows for the automatic delivery of a 911 caller’s location in addition to their phone number with their 911 call. When a call taker at a Public Safety Answering Point (PSAP) receives a 911 call, they know where the caller is and where to send help because that caller’s location is displayed right on their screen. This is particularly critical in those emergencies where a caller can’t speak: medical emergencies, emergencies in progress, etc. The question is, do businesses need to pay special attention to how E911 functions in the enterprise?

VoWiFi 911 and Application of Proximity Check

By: Marcus Andronici, Principal Sales Engineer

In recent blogs, we talked about the key components of a VoWiFi 911 solution, as well as VoWiFi user set-up and provisioning. Now I’m going to explore a specific VoWiFi 911 call feature: proximity check.

Wireless location has historically been derived from the cell tower and VoIP location from the subscriber’s pre-provisioned address. However, because of advancements in location-based technology with today’s mobile handsets, it’s now possible to acquire and utilize latitude/longitude (X/Y) directly from a 911 caller’s device.

The Importance of Identifiable E911 Locations for First Responders

Someone in distress, unable to speak, dials 911 from their VoIP system at the office. The Public Safety Answering Point (PSAP) receives the call with the following E911 location information: 123 Main Street, Marketing department, port 16. The PSAP then transmits the location data to first responders. However, once on-site, the emergency team finds a campus that consists of numerous multi-story buildings. Where is the Marketing department, and where is the location of port 16? First responders spend seconds, if not minutes, trying to pinpoint the precise location of the caller.

PSAPs need to transmit location information in a format that first responders can easily identify and understand. When seconds count and emergency teams need to find a person requiring immediate assistance, they simply don’t have time to figure out the location of a port or department within an enterprise’s facility.

4 Key Features of a VoWiFi 911 Solution

By: Marcus Andronici, Principal Sales Engineer

Handset technology has evolved to the point that WiFi calling can often be a seamless experience for your users (on WiFi-enabled devices). For competitive carriers, VoWiFi is a means to:

  • Move calls off your networks to alleviate data/network demands.
  • Deliver differentiated services to your subscribers and reduce subscriber churn.
  • Provide coverage when and where wireless calls aren’t possible i.e., indoor environments where coverage can be limited.
  • Expand your carrier footprint while reducing roaming costs, thus eliminating the need to put additional roaming agreements in place.

Behind the Scenes at West’s Emergency Call Relay Center (ECRC)

By: Tricia McConnell, Sr. Marketing Communications Manager

On a Friday afternoon in the Emergency Call Relay Center (ECRC) at West, call volume is steady but manageable. A vehicle collides with a bus, which triggers a 9-1-1 call from the car’s telematics system. A registered nurse from a 24-hour hotline reports a caller complaining of chest pains and nausea. The ECRC call takers identify the location and nature of these emergencies then conduct warm transfers by contacting the appropriate public safety answering point (PSAP) and confirming that the dispatcher and caller can communicate before dropping off.

The mood in the room back in October 2012 was significantly more intense. Then, as Hurricane Sandy surged up the east coast, PSAPs in impacted areas struggled to manage the overwhelming 9-1-1 call volume. The ECRC staff and other West employees worked extended shifts and through scheduled days off to help PSAPs respond to incoming 9-1-1 calls.

Before You Go VoLTE, Read This

When I’ve spoken with non-nationwide carriers recently, I’ve noticed that there are more and more concerns about Voice over LTE (VoLTE), especially when discussing E9-1-1 for VoLTE. Questions vary widely. Here’s a list of six key areas (in no particular order) before embarking on a VoLTE project.

  • If your network is hosted, develop your VoLTE project plan with your IMS core and UTRAN solution provider(s) and, if you’re already working with Intrado, include us in the 9-1-1 portion of the project plan.  Specifically for VoLTE E9-1-1, you’ll need to consider the call path changes in your IMS core and new signaling e.g. diameter.
  • Consider location servers for Phase 2 location. You’ll need either an eSMLC network for E9-1-1 location or you’ll need to identify a solution provider, like Intrado, for hosted eSMLC.
  • Start the conversation early about SIP for voice path and signaling to your MME for location. The right partner should review all the signaling and connections needed to support VoLTE E9-1-1. Choose a provider that supports the signaling connection needed to support home and roaming device location queries in their MME. Remember, VoLTE is a new voice path that is IP-based (or SIP) and uses new signaling for location queries to and from the eSMLC to the MME and the devices.
  • Create a network checklist for all the regulatory requirements and changes that have to be supported with VoLTE i.e., E9-1-1 and CALEA. It’s essential to engage with the right provider early for planning and testing interoperability of your IMS voice core and MME.
  • As most carriers know, the customer voice call experience is key to a successful VoLTE launch. Not all devices are equal, so you’ll need to look at VoLTE support in your device ecosystem. We encourage testing each VoLTE device out to the cell site edge to ensure you don’t lose significant coverage when you migrate your customers from 3G voice to VoLTE. Beyond providing the best call quality possible, the new FCC rules on wireless indoor location means location technology support is more critical than ever.
  • Network location performance is a crucial component to a successful VoLTE launch. You need to consider tools that help you optimize location performance on your network, such as Intrado’s Location Performance Management (LPM) solution. This tool helps carriers meet compliance for coming changes in E9-1-1 accuracy, as well as enhancing overall commercial location performance on your network. You’ll be able to pinpoint which 3G areas are optimal to turn down first—and you’ll improve your overall customer experience as you roll out  exciting new services with VoLTE.
