Re: [Ecrit] Additional text - location mech - wireless & mobilitysupport

["Stark, Barbara" <bs7652 at att.com>]

I don't understand this proposed sentence: " Requirements for endpoint
location determination vary, 
depending on whether an endpoint's resulting location is based 
on internal (device-based) or external (network-based) 
measurements, or by manual provisioning - for mobile capable, or 
fixed environment endpoints, respectively.  "

That is, I understand the first part, up to the dash "-". I don't
understand the part after the dash "-", specifically the use of the word
"respectively".

Is a Femtocell access point (which connects via Ethernet into the LAN of
a home network that is connected by a broadband connection to the
Internet) mobile capable or fixed? The FAP itself is certainly *not*
mobile. It will be able to use GPS or AGPS (with SUPL) to get its
location determined. It will also need to be able to use other methods
to get its location when it finds itself in a basement, unable to make
use of GPS.

Is a GSM/Wi-Fi PDA that is in someone's basement (where GPS doesn't
work, and they can't get a cellular signal), and is connected via Wi-Fi
into a home network, supposed to use internal or external measurements?
It's definitely mobile capable.

Brian:
Below is a proposed change in text to the current phonebcp-06 that adds
some background for various requirements later in the draft that specify
"wireless" and "mobile", per remarks made in the 11/20 ECRIT wg meeting.

1. Section 6. Location and its role in emergency calls

change from:

In Internet emergency calling, where the endpoint is located 
is "determined" using a variety of measurement or wiretracing 
methods.  Endpoints may be "configured" with their own location 
by the access network.

change to:

In Internet emergency calling, the endpoint location 
is "determined" using a variety of measurement or wiretracing 
methods.  Requirements for endpoint location determination vary, 
depending on whether an endpoint's resulting location is based 
on internal (device-based) or external (network-based) 
measurements, or by manual provisioning - for mobile capable, or 
fixed environment endpoints, respectively.  Once location has 
been determined, endpoints may then be "configured" with their 
own location by the access network via some Location Configuration 
Protocol (LCP).
