Q. What is the interface between HSS (Home Subscriber Server) and 3GPP AAA Server in a Non-Roaming GAN architecture?

View solution

Q. State TRUE or FALSE.
In a Roaming GAN architecture, PCRF element is dividedas vPCRF (Visitor PCRF) and hPCRF (Home PCRF) elements.

Q. In an Evolved Packet System (EPS), what is the interface between vPCRF and hPCRF in Roaming architecture?

View solution

Q. State TRUE or FALSE.
In a Roaming GAN architecture, ePDG uses vPCRF and PDN-Gateway uses hPCRF.

Q. Rove-In refers to hand-over of call to ___ network.

View solution

Q. Rove-out refers to handing of Call to ___ network.

View solution

Q. To provide roaming of calls between Wi-Fi and 3GPP networks, the user SIM contains ____.

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.

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.
