Month Year doc.: IEEE 802.11-yy/xxxxr0 November 2006 Abstract The STA shall include the location information in the request to establish an emergency session in IMS emergency call Initial location information can be determined from the MAC address of AP and put into the emergency call request This proposal describes an idea which facilitates the interaction between DSS and SSPN through SSPN interface to be able to support emergency call feature in WLAN. No change on currently defined architectures and frames for location services support is required. At the end of the presentation, there will be a motion to determine next steps.

Location Information for IMS Emergency sessions Month Year doc.: IEEE 802.11-yy/xxxxr0 November 2006 Location Information for IMS Emergency sessions Location information is needed for 2 main reasons in IMS emergency services. The initial purpose of the location information is to enable the network to determine which PSAP serves the area where the terminal is currently located, so that the network can route the emergency session to the correct PSAP. The second purpose is for the PSAP to get more accurate or updated location information for the terminal during or after the emergency session. If the terminal has location information available, the terminal shall include the location information in the request to establish an emergency session. The location information may consist of network location information, that is the Location Identifier, and/or the Geographical location information. Donghee Shim et al, LG Electronics, Inc.

Location Information in WLAN November 2006 Location Information in WLAN 802.11k or 802.11v location information capability is enabled on AP if AP is located in a regulatory domain that requires this. In 802.11v location proposal, AP delivers the location of a STA to a STA or, STA calculates its location based on time of arrival. In 802.11k location proposal defined a mechanism for carrying location information (per RFC3825) from one 802.11 STA/AP to another 802.11 STA/AP 802.11v has defined the positioning mechanism to locate the STA Donghee Shim et al, LG Electronics, Inc.

Location Information in WLAN for IMS Emergency sessions November 2006 Location Information in WLAN for IMS Emergency sessions The location of AP would be enough as the initial location information for IMS emergency call Assuming that AP does not have its location previously, only available location information to be used as the initial location information for IMS emergency call would be MAC address of AP However, until now, MAC address of AP has not been considered a kind of location information If AP provides the its MAC address to SSPN, then SSPN can provide the geographical location to AP after looking up the mapping table (a data base of the locations of APs are available) and SSPN can control and update the database if needed This location can be transferred to the STA, then the STA can initiate the emergency call request with an initial location information Donghee Shim et al, LG Electronics, Inc.
