Q. The authentication of user SIM to the GANC is done using ___.

View solution

Q. State TRUE or FALSE.
The mobile periodically informs to GANC (Generic Access Network Controller) about the cellular network parameters so that the call may be handed over to the Cellular network if required.

View solution

Q. State TRUE or FALSE.
In Non-Roaming scenario, the mobile can use any local IP of the WiFi network to make and receive calls. In a Roaming scenario, unique global IP is mandatory.
