Question: In an IMS centralized services context, when mapping IMS procedures to GSM procedures due to forking on the remote side (e.g., MSIM scenario), what challenge does the MSC Server enhanced for SeDoC face towards the GSM device?
Option 1: Handling a single early SIP dialogue to multiple GSM dialogues.
Option 2: Managing uni-directional media paths exclusively.
Option 3: Supporting SRVCC without the Sv Interface to MME.
Option 4: Mapping multiple early SIP dialogues to one GSM dialogue.
Explanation: In scenarios involving forking on the remote side, such as MSIM (Multiple Subscriber Identity Module) scenarios, the MSC Server enhanced for Single Device with Multiple Addresses (SeDoC) must manage multiple simultaneous early SIP dialogues. The key challenge here is to correctly map these multiple SIP dialogues into a single coherent GSM dialogue that can be understood and processed by the GSM device, ensuring seamless communication without confusing the device with multiple, seemingly unrelated dialogues. This requires sophisticated handling of signaling to maintain call integrity and user experience.
