Every second counts in critical communications.


Building a broadband public safety backhaul network with utmost resiliency for NG9-1-1

Every packet counts. Therefore high resiliency and service availability are key design considerations when deploying a public safety microwave networks. This session discusses how a Nokia backhaul network solution, based on IP/MPLS and packet microwave, with a multi-ring topology, can provide utmost resiliency for deploying an Emergency Service Network for NG9-1-1. From fault detection, OAM to rapid network restoration, we will discuss how IP/MPLS riding atop packet microwave can leverage full path diversity to restore connectivity even in multi-failure scenarios, ensuring highest network availability for first responders to get their jobs done safely.

Evolution of Next Generation 9-1-1

• The evolution of emergency calling beyond the traditional voice 9‐1‐1 call has caused the current E9‐1‐1 system to no longer be able to support the needs of the next generation personal communications

- The spread of highly mobile, dynamic communications requires capabilities that do not exist today for

9-1-1 emergency callers.

• NG9-1-1 is the evolution of Enhanced 9-1-1 to an all-IP-based emergency communications system

- Next Generation 9‐1‐1 (NG9‐1‐1) networks replace the existing narrowband, circuit switched 9‐1‐1 networks which carry only voice and very limited data.

- Support of real-time text, data, images and video for emergencies that are common in personal communications and the need for inter-communications across states, between states, and across international boundaries require a NG9-1-1 system design with the ability to:

• Enable 9-1-1 calls from a variety of networked devices.

• Provide quicker delivery and more accurate information to responders and the public alike. Delivery will incorporate better and more useful forms of information (e.g., real-time text, images, video, and other data).

• Establish more flexible, secure, and robust PSAP operations with increased capabilities for sharing data and resources, and more efficient procedures and standards to improve emergency response.

• Enable call access, transfer, and backup among PSAPs and between PSAPs and other authorized emergency entities.


NG9-1-1 Summary Definition

• NG9‐1‐1 is a system comprised of hardware, software, data and operational policies & procedures to:

- Process all types of emergency calls including non‐voice (multi‐media) messages

- Acquire and integrate additional data useful to call routing and handling

- Deliver the calls/messages and data to the appropriate PSAPs and other appropriate emergency entities

- Support data and communications needs for coordinated incident response and management

- Provide a secure environment for emergency communications

• The basic building blocks required for NG9‐1‐1 are:

- Emergency Services IP network (ESInet)

- International standards compliant IP functions

- Internet engineering task force (IETF) based IP protocol standards

- Databases and data management

- Security

- Human processes


Emergency Services IP Network (ESInet)

• The primary element of the NG9-1-1 system is the Emergency Services IP Network.

• ESInets use broadband, packet switched technology capable of carrying voice plus large amounts of varying types of data using Internet Protocols and standards.

• ESInets are engineered, managed networks, and are intended to be multi‐purpose, supporting extended Public Safety communications services in addition to 9‐1‐1.

• NG9‐1‐1 assumes that ESInets are hierarchical, or a “network of networks” in a tiered design approach to support local, regional, state and national emergency management authorities.

• A local ESInet, which may typically be county wide, will be interconnected to neighboring county’s ESInet for mutual aid purposes. Because ESInets are IP-based, such interconnections will allow any agency to communicate with any other agency or service on any of the interconnected ESInets.

To address increased bandwidth and resiliency requirements:

1. Separate 9500MSS-1 on each link reducing the single point of failure should a microwave node experience an issue.

2. Identified ring connections providing additional redundant paths through out network

3. Hot-standby links on spur connections reducing single point of failure
