Next Generation 9-1-1 (NG9-1-1) in California

​The California 9-1-1 Emergency Communications Branch has provided coordination and direction to ensure that the people of this state enjoy the best 9-1-1 call processing functionality in the nation. While the existing 9-1-1 system has been a success story for more than 40 years, it has been stretched to its limit in the present environment. Unfortunately, it was never envisioned that the current 9-1-1 system would receive calls and data from new and emerging technologies as diverse as what we see today.

The need to transform California’s legacy 9-1-1 system into a Next Generation 9-1-1 (NG9-1-1) system is upon us. The IP based network of NG9-1-1 will allow for capabilities such as location based routing, policy based routing and dynamic call routing between Public Safety Answering Points (PSAPs). Additionally, applications like text, video, and photos along with continual advancements in communications technology create the desire for a more advanced system to access emergency care.

The CA 9-1-1 Branch has taken significant steps towards the implementation of a NG9-1-1 infrastructure in California. In December 2010, the Proposed California NG9-1-1 Roadmap was released, which “identifies the steps and tasks necessary to assess, plan, design, test, implement, and maintain a comprehensive NG9-1-1 system in CA.” The CA 9-1-1 Branch is also actively engaged in five pilot projects to assist in determining the best path forward for the State of California.

While it is important to examine how technology affects 9-1-1 today, it is equally important to understand the operational expectations and impacts to California PSAPs. As such, the CA 9-1-1 Branch conducted a series of six Public Meetings on Next Generation 9-1-1 in California during the first quarter of 2011. The CA 9-1-1 Branch will continue to solicit input from our stakeholders and partners through focus groups and public meetings to foster collaboration and gather critical information on how NG9-1-1 will best serve the PSAPs and California’s citizens.

The CA 9-1-1 Branch is currently engaged in five NG9-1-1 pilot projects in various regions throughout the state. These projects are designed to allow the state to implement, monitor and evaluate various NG9-1-1 platforms in order to validate each solution against requirements identified as necessary for NG9-1-1 in California. These projects will also further define and help structure the statewide strategy that will be used for NG9-1-1 implementation. The status of each of these pilot projects is outlined below along with a link to the fact sheet that offers a brief description. Updates will be made available as the projects progress.

Enhanced 9-1-1 Grant Project

The 9-1-1 Office submitted this request for information to gain comments from vendors interested in providing Enhanced 9-1-1 (E9-1-1) database and network services in California. The 9-1-1 Office intends to solidify the requirements in the NGEN Database Specification to obtain multiple vendor responses for the formal RFP.

One of the highlight features of the hosted configuration is the “any to any” feature, allowing call takers to “roam” from their PSAP to another PSAP within the project and resume taking their calls as if they were at their own workstation. Gridley Police Department (PD) recently had the opportunity to use this feature, leaving their center for two days due to building maintenance and answering calls at Oroville PD – everything functioned as planned!

Beyond Butte County, the Enhanced 9-1-1 Grant Project has seen the completion of site remediation at all 37 PSAPs, and all equipment, including the NG9-1-1 trunks, has been installed. Proof of concept testing for new NG9-1-1 network connectivity has also been completed at all 37 PSAPs. In January 2012, initial proof of concept testing for X/Y (location based) routing with Verizon Wireless also took place with the first seven PSAPs. The goal remains to deploy live wireless traffic on this solution in the third quarter of this year.

Imperial County Project

Brawley PD, Calexico PD, El Centro PD, and Imperial County Sheriff were all cutover to a hosted configuration at the end of September 2011. Like Butte County, Imperial County is also utilizing a dual CPE host configuration. An overall success, the PSAPs continue to work through various issues with the vendor parties. The CA 9-1-1 Branch will be working with the PSAPs in order to develop a project summary and evaluate this specific hosted environment. The implementation of this solution in addition to the solution in Butte County will enhance the CA 9-1-1 Branch’s ability to compare the feature functionality of both solutions and determine the best path forward.

Pasadena RING Project

On January 10, 2012, the CA 9-1-1 Branch participated in the Kick off meeting for the Pasadena RING Project. Implementation is expected to begin in the second quarter of this year. The first phase of the Pasadena RING Project will include Alhambra PD, Beverley Hills PD, Burbank PD, Glendale PD, Pasadena PD, San Fernando PD, Sierra Madre PD, and Verdugo Fire Department. This Project will be the first end to end turnkey network based NG9-1-1 solution implemented in California.

Ventura County Project

In Ventura County, Oxnard PD, Simi Valley PD, and Ventura County Sheriff are excited to be moving forward with the installation of their hosted project. Network build out for the Ventura Hosted Project has begun and PSAP implementation is expected to begin in the second quarter of 2012.

Mendocino County Project

The Mendocino County Project is comprised of three PSAPs – Mendocino County Sheriff, Ukiah PD, and Willits PD. The PSAPs, their consulting firm, and the CA 9-1-1 Branch have reviewed and evaluated the various responses to the Request for Information (RFI). The Project’s consulting firm will prepare recommendations to be submitted to the CA 9-1-1 Branch that outline the solution that best meets the needs of the participating PSAPs.
