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 to 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. The minimum set of rules developed must address all call
diversion capabilities present in the current E911 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 that 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 Emergency Service Routing Proxy
(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.
