The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.11. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.11 Working Group.

2. doc.: IEEE 802.11-07/0032r1 Submission January 2007 Donghee Shim et al, LG Electronics, Inc.Slide 2 Abstract The recommendations are provided to resolve the comments from 11u internal review regarding emergency call support in 11u draft

3. doc.: IEEE 802.11-07/0032r1 Submission January 2007 Donghee Shim et al, LG Electronics, Inc.Slide 3 Comment 1 – ID 33 in 06-1857-02 Comment in section 7.2.4.7: STA should get the Default Emergency Services from AP Recommendation from commenter: Delete Default Emergency Services Realm IE from Probe Request Question & Recommendation: Why ‘Default Emergency Services Realm IE’ in the Probe Request? If there is no special reason to have ‘Default Emergency Services Realm IE’ in the Probe Request, we can delete that as commenter proposed.

Add Default Emergency Services Realm IE to Probe Response

5. doc.: IEEE 802.11-07/0032r1 Submission January 2007 Donghee Shim et al, LG Electronics, Inc.Slide 5 Comment 3 - ID 49 in 06-1857-02 Comment 3 in section 7.3.2.36: TGu standard shall not impose guaranteed QoS up to the PSAP as this node is outside the.11 network Recommendation from commenter: QoS shall only be guaranteed within the.11 network. Outside the.11 network QoS guarantees shall only be recommended. Thought: Agreed. Follow up commenter’s recommendation. However, it is not clear what is the specific proposal of original commenter. Should we rephrase “DS supports end-to-end QoS from STA to all APs in ESS to PSAP” or delete this condition?

6. doc.: IEEE 802.11-07/0032r1 Submission January 2007 Donghee Shim et al, LG Electronics, Inc.Slide 6 Comment 4 - ID 50 in 06-1857-02 Comment 4 in section 7.3.2.36: If the Expedited Bandwidth Request bit has to be set to 1 there would not be any possibility to have emergency call services without the use of expedited bandwidth request. Recommendation from commenter: Setting of the Expedited Bandwidth Request bit to one shall not be compulsory, but optional. Recommendation: Agree. See the resolution slide for comment 8

7. doc.: IEEE 802.11-07/0032r1 Submission January 2007 Donghee Shim et al, LG Electronics, Inc.Slide 7 Comment 5 - ID 46 in 06-1857-02 Comment 5 in section 7.3.2.36: Change the "AP" to "STA" Recommendation from commenter: Make changes as indicated by the comment Comment and Recommendation: It is not clear which ‘AP’ should be changed to ‘STA’. Let’s go back to the original commenter

8. doc.: IEEE 802.11-07/0032r1 Submission January 2007 Donghee Shim et al, LG Electronics, Inc.Slide 8 Comment 6 - ID 47 in 06-1857-02 Comment 6 in section 7.3.2.36: Should not refer to other TG in the draft. Recommendation from commenter: To remove the reference of 802.11k & 802.11v in the text and place it into a Editorial Note. Comment and Recommendation: Agree. However, it is not clear what is the exact relationship between TGu and TGv / TGk to get the location of the STA to support emergency call

9. doc.: IEEE 802.11-07/0032r1 Submission January 2007 Donghee Shim et al, LG Electronics, Inc.Slide 9 Comment 7 - ID 48 in 06-1857-02 Comment 7 in section 7.3.2.36: There is no definition of PSAP Recommendation from commenter: To define the PSAP in clause 3 & 4 Resolution: Add following definition in clause 3: Public Safety Answering Point (PSAP): A physical location, where emergency calls from the public are received. Resolution (cont’): Add following abbreviation in clause 4: Public Safety Answering Point (PSAP)

10. doc.: IEEE 802.11-07/0032r1 Submission January 2007 Donghee Shim et al, LG Electronics, Inc.Slide 10 Comment 8 - ID 2 in 06-1857-02 Comment 8 (general): In document IEEE802.11- 06/1039r0 three new features are presented in order to provide emergency call services. However, only the feature employing expedited bandwidth request seems to be a non-informative part of the actual draft. Recommendation from commenter: The draft shall include the option of having emergency call services not necessarily using expedited bandwidth request, i.e. by using public security credentials or open authentication SSIDs

11. doc.: IEEE 802.11-07/0032r1 Submission January 2007 Donghee Shim et al, LG Electronics, Inc.Slide 11 Comment 8 (cont’) Resolution: Replace current ‘Interworking Capability Information element format’ by the following table and AP should set one of three options for the emergency call support B0B1B2B3B4B15 QoS MAP Public Security Credentials Expedited Bandwidth Request ESOReserved 111112
