Question: What is a requirement for allocating an International Mobile Subscriber Identity (IMSI) in the context of General Packet Radio Service (GPRS) subscribers?
Option 1: A unique IMSI must be allocated to each packet-domain subscriber, including those with GPRS-only subscriptions.
Option 2: IMSI allocation is optional for GPRS-only subscribers but mandatory for all other packet-domain subscribers.
Option 3: A shared IMSI can be allocated to multiple GPRS-only subscribers for efficiency.
Option 4: IMSI allocation is based on the subscriber's chosen data plan, with unique IMSIs only for premium plans.
Explanation: In telecommunications, uniquely identifying each subscriber is crucial for secure and efficient network management. Allocating a unique International Mobile Subscriber Identity (IMSI) to each packet-domain subscriber, including those with GPRS-only subscriptions, ensures that the network can accurately authenticate, authorize, and manage services for each individual user. This approach prevents potential security breaches and service conflicts that could arise from shared or absent identifiers.
