Question: What is the primary purpose of assigning one or more Temporary Identities to a CTS Mobile Subscriber (CTS-MS) in a telecommunications network?
Option 1: To facilitate efficient handover procedures between different base stations.
Option 2: To enhance the security of data transmission by frequently changing identifiers.
Option 3: For use in paging and requesting access to the network, ensuring privacy and efficient resource allocation.
Option 4: To enable the billing system to accurately charge for services based on subscriber identity.
Explanation: Assigning temporary identities to a CTS-MS is crucial for maintaining user privacy while allowing the network to efficiently manage resources, especially during initial access requests and paging processes. This approach ensures that permanent identifiers are not exposed unnecessarily, thus enhancing security and facilitating efficient network operations.
