Answer 1

Answer:

GPRS needs the following parts of a typical GSM

(C) The circuit-switched core for localization and authentication

Answer 2

GPRS needs the following parts of a typical GSM (D) None of these​.

Explanation:

The GSM core network is only little impacted by the introduction of GPRS. To provide a routing path for packet data between the wireless terminal and a gateway node, all that is required is the addition of new packet data switching and gateway nodes, as well as an upgrade to existing nodes.

Does not need any part of GSM:

• The GSM architecture is made up of three key interconnected subsystems that communicate with each other and with users via network interfaces.

The packet-switched core for data transmission:

• Packet switching is a way of organising data that is transferred over a digital network into packets in telecommunications.

The circuit-switched core for localization and authentication:

• The process of tailoring content, products, and services to unique local markets is known as localization.
