Executive Overview  

An important feature of NG9-1-1 is the ability of the system to adapt to outages, excessive call volumes, emergencies and normal scheduled PSAP outages. The Policy Routing Function (PRF) described in 08-003 is the function that handles the diversion of calls. To support the PRF, Policy Routing Rules (PRRs) must be developed. These PRRs define where calls are diverted if the target PSAP is unreachable. This Working Group’s charter was to define a template to guide the development of these PRRs. To that end, the committee developed templates to facilitate the PRRs that a 9-1-1 Authority must develop for any new NG9-1-1 System. This minimum set of rules addresses situations requiring call diversion present in the current E9-1-1 system. A 9-1-1 Authority may choose to implement additional and/or enhanced PRRs to divert calls in a manner that takes advantage of capabilities available in a NG9-1-1 system there are not available in E9-1-1 systems.

The template developed is intended to facilitate a discussion between a 9-1-1 Authority and its ESRP vendor. By utilizing the template, PRRs can be described in a way that is understandable by the 9-1-1 Authority and specific enough to be implemented by the vendor.

Without the creation of PRRs, a NG9-1-1 system will not be able to divert calls to an alternative PSAP when the target PSAP is unavailable. Implementation of the PRRs is a necessary step in the deployment of a NG9-1-1 system.
