Question: In a Public Land Mobile Network (PLMN), when establishing communication between a User Equipment (UE) in one network and a terminal in another, which of the following types of terminating networks is also a mobile network, similar to the originating network?
Option 1: PSTN (Public Switched Telephone Network)
Option 2: ISDN (Integrated Services Digital Network)
Option 3: PLMN (Public Land Mobile Network)
Option 4: PSPDN (Packet Switched Public Data Network)
Explanation: The correct answer is Option 3, PLMN, because the question specifically asks for a terminating network type that is also a mobile network, similar to the originating network. According to the context, communication can be established between a UE in one PLMN (originating network) and a terminal in another PLMN (terminating network), indicating PLMN is indeed a possible type of terminating network when considering mobile-to-mobile communications across different networks. PSTN, ISDN, and PSPDN are all types of non-mobile networks, making them incorrect choices for this specific scenario focusing on mobile network-to-mobile network communication.
