Recommended Method(s) for Location Determination to
Support IP-Based Emergency Services Technical Information Document
document is the first edition of what will be a comprehensive document
addressing many access network configurations. This edition has a narrow
solutions focus and will address only the automated mechanisms for the
residential broadband market, manually configured location mechanisms
for end-points are not discussed. User-provided location information is
beyond the scope of this document. Revised editions of this document
will add new sections to address enterprise, hosted and mobile access
In order to understand the residential broadband market
it is important to understand a few things about how these services are
delivered. Detailed discussions throughout this document describe the
technological and organizational structures that are required to deliver
these services, and the impacts that these have on the potential to
deliver workable location determination and acquisition solutions.
The document is based on the requirements in [TRD] and
reiterates those requirements as the basis for the proposed solutions.
For convenience of the reader, the referenced requirements are excerpted
from the TRD and reproduced in Section 4 of this document. These
requirements are deemed to be desirable characteristics of any solution
regardless of the access technology.
This release of the document describes solutions that
meet the proposed requirements for automatically determining the
location of IP devices inside a residential broadband network. It also
provides recommended solutions to allow the network-determined location
to be acquired by nodes needing it in emergency applications.
This document should be reissued as new location
determination and acquisition solutions are identified for residential
broadband and other IP access networks. This document is expected to be
reissued to address enterprise, WiFi (enterprise and community), 3G
cellular and WiMAX access networks.
