Question: In a roaming scenario where PCC is deployed in the Home Public Land Mobile Network (HPLMN) but not in the Visited Public Land Mobile Network (VPLMN), and a Gateway (BBERF) is used, what happens to dynamically allocated resources associated with specific EPS Bearers when the User Equipment (UE) moves from the HPLMN to the VPLMN?
Option 1: The dynamically allocated resources are seamlessly transferred to the VPLMN.
Option 2: The UE continues to receive service based on dynamic policies from the HPLMN.
Option 3: The VPLMN allocates new resources based on its own dynamic policy provisioning.
Option 4: The dynamically allocated resources no longer apply after this transition, and the UE receives service according to static policies or static subscriber policies.
Explanation: When a UE moves from an HPLMN (where PCC is deployed) to a VPLMN (where PCC is not deployed), and a BBERF is employed, the dynamic policy provisioning that was in place in the HPLMN no longer applies. In the VPLMN, without local PCC deployment, the UE can only receive services based on static policies or subscriber policies defined outside the PCC framework, leading to the loss of dynamically allocated resources associated with specific EPS Bearers.
