TD S2 160011 LS from CT WG4: LS on Network asserted WLAN Location Information for PDN connection establishment over S2b. (CT WG4) (Revision of TD S2 153752).
Abstract: Clause 4.5.7.2.8 of TS 23.402 defines the means to transfer network provided WLAN Location Information from the WLAN Access Network to the ePDG via the 3GPP AAA Server.
When available, this information is sent by the ePDG to the PGW over S2b during an Initial Attach for emergency session.
In the corresponding Stage 3 extensions, CT WG4 tentatively specified that the network provided WLAN Location Information is signalled over SWm and S2b, when available, during the establishment of emergency and non-emergency PDN connections, subject to a final decision by SA WG2.
This allows a more generic behaviour, and it was assumed that providing that location information over S2b would also be useful for non-emergency PDN connections.
CT WG4 made similar tentative changes for the UE local IP address and port number over S2b, i.e. these parameters are also reported for emergency and non-emergency PDN connections.
Action: CT WG4 kindly asks SA WG2 group to respond to CT WG4 whether they agree on the above extensions for non-emergency PDN connections.
