Question: In a Location Services (LCS) scenario, what is the primary responsibility of the Location IMS – Interworking Function (LIMS-IWF) in the home network of the target user?
Option 1: To route LCS service requests to the requesting network based on an MSISDN.
Option 2: To authenticate the target user for LCS services using SIP-URI.
Option 3: To provide the target user's location to emergency services directly.
Option 4: To determine the appropriate Home Subscriber Server (HSS) and obtain the MSISDN associated with a given IMS Public User Identity (SIP-URI).
Explanation: The LIMS-IWF in the home network of the target user is tasked with identifying the suitable HSS for querying and retrieving the MSISDN linked to a provided IMS Public User Identity (SIP-URI), crucial for resolving identities and facilitating location services across different networks.
