2. Introduction
The “ranging purpose indication” in m only has one code to indicate “emergency call”, initially designed for the citizen-to-authority type of emergency service (e.g., E911 in the U.S.).
To support authority-to-authority type of National Security/Emergency Preparedness (NS/EP) service with multiple user priority levels (e.g., Emergency Telecommunications Services [ETS] as specified in the WiMAX Forum Release 1.6 documents and ITU-T Y.2205), the original single code is not sufficient to distinguish the authority-to-authority call from the citizen-to-authority call.
We propose to use the original code to indicate E911 service, and add another code for NS/EP service.

3. Comment 1 Original text: Proposed text:
During the network entry, the ABS shall allocate the emergency service FID through AAI_RNG-RSP upon receiving AAI_RNG-REQ with Ranging Purpose Indication set to code 0b0010.
Proposed text:
Add the following:
“During the network entry, the ABS shall allocate the NS/EP service FID through AAI_RNG-RSP upon receiving AAI_RNG-REQ with Ranging Purpose Indication set to code 0b10000.”
First page: 338; First line: 48

4. Comment 2 Original text: Proposed text:
The AMS may request for Emergency Service flow setup during initial ranging process by setting the Ranging Purpose Indication to code 0b0010 in the AAI_RNG-REQ message. Default service flow parameters are defined for emergency service flow.
Proposed text:
“The AMS may request for Emergency Service flow setup during initial ranging process by setting the Ranging Purpose Indication to code 0b0010 for E911 type services and code 0b1000 for NS/EP services in the AAI_RNG-REQ message. Default service flow parameters are defined for emergency service flow.”

5. Comment 3 Original text: Proposed text: Under Value/Note column
0b0010 = ranging request for emergency call setup. When this value is set, it indicates AMS action of Emergency Call process.
0b1000 – 0b1111 = reserved.
Proposed text:
“0b0010 = ranging request for emergency (e.g. E911) call setup. When this value is set, it indicates AMS action of Emergency Call process.
0b1000 = ranging request for NS/EP call setup. When this value is set, it indicates AMS action of NS/EP Call process.
0b1001 – 0b1111 = reserved”

NS/EP service FID 4
A FID number assigned within the transport FID numbers according to Table 652
It shall be included when an ABS sends an AAI_RNG-RSP in response to an AAI_RNG-REQ with Ranging Purpose Indication set to code 0b1000 when an AMS performs initial ranging.
