A DNS query is performed "inside the secure connection" to retrieve the IP-address of the Provisioning GANC.

Test procedure
Make the MS join the AP so that the Discovery procedure is kicked off.
The MS will derive SEGW associated with provisioning GANC and provisioning GANC from the IMSI.
The SS is supposed to answer the Discovery Request message before timer TU3901 expires.
Use a default GANC associated with the same SEGW as the provisioning GANC in order to simplify the test sequence.

- If the MS was provisioned with an IP address of the GANC-SEGW, (or received it in the GA-RC DISCOVERY ACCEPT or GA-RC REGISTER REDIRECT message), then the certificate shall contain an IPaddress SubjectAltName that matches that address.
- If the MS was provisioned with an FQDN of the GANC-SEGW, or received it in the GA-RC DISCOVERY ACCEPT or GA-RC REGISTER REDIRECT message, then the certificate shall contain a DNSname SubjectAltName that matches that FQDN.
- If the MS derived the FQDN of the Provisioning GANC-SEGW, then the certificate shall contain a DNSname SubjectAltName that matches that FQDN.
If the MS and GANC-SEGW are not able to set up the SA for any other reason than EAP-SIM or EAP-AKA authentication failure, and the current GANC-SEGW is the SEGW associated to the Provisioning GANC, the MS shall act as if a "Lower layer failure in the MS" has occurred and act as defined in sub-clause 5.6.2.

- if found, the MS shall initiate the GAN Registration procedure towards the stored Serving GANC
When the MS receives GA-RC REGISTER ACCEPT message, it shall:
- Start Keep alive mechanism as defined in sub-clause 6.5 using the received TU3906 Timer IE
The GANC may at any time initiate the deregistration of a MS by sending the GA-RC DEREGISTER message to the MS. When the GA-RC layer in the network has submitted the GA-RC DEREGISTER message to the TCP layer, it may initiate release of its half of the bidirectional TCP connection

683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 81.2.1.2.3 Method of test | Initial conditions
System Simulator:
- 1 GAN cell, default parameter
- 1 GSM cell, default parameter
- Public DNS without knowledge of the serving GANC’s FQDN
- DNS inside of the serving SEGW associated with the serving GANC
- DNS inside of the default SEGW associated with the default GANC
Mobile Station:
- MS has stored a serving GANC associated with the AP-ID
- MS has not stored a serving GANC associated with the GSM cell (CGI)
- MS in state GA-RC DEREGISTERED
Foreseen final state of the MS
The MS will change state to GA-RC REGISTERED.
Test procedure
Make the MS join the AP so that the Registration procedure is kicked off.
The SS is supposed to answer the Registration Request message with Registration Accept before timer TU3904 expires.
The SS requests the MS to deregister. The GSM cell is then removed. The MS should now attempt to register using the stored AP-ID.
