Abstract
Emergency call numbers are necessary when a user makes an emergency call.
It is impossible a terminal to store all the emergency call numbers of each network. Therefore network should provide these numbers.
Currently, 11u draft v1.0 does not support that STAs can obtain emergency numbers from network.
We propose a method to provide emergency call numbers to STAs by adding information to GAS protocol.

Discussion
Whenever a user makes an emergency call, emergency call numbers are needed.
Emergency call numbers of each SSPN are different.
If not provided by network, STAs should store all the emergency call numbers of each SSPN.
 overhead!

4. Discussion (cont’d) July 2007
In 3GPP IMS call, the network may provide a capability to enable a terminal to obtain local emergency numbers.
This was already debated (07/0033r1)
TS – IP Multimedia Subsystem (IMS) emergency sessions
Defines the stage-2 service description for emergency services in IMS, including the elements necessary to support IP Multimedia emergency services
This document covers also the Access Network aspects that are crucial for the provisioning of IMS emergency services including fixed broadband access aspects, GPRS and 3GPP/WLAN Interworking.
TS – a procedure to provide local emergency numbers for UMTS and GPRS access
By sending the Emergency Number List IE when a UE moves to a VPLMN where its emergency numbers could be changed
