Question: In which of the following scenarios is the service continuity procedure applicable for L2 U2N relay?
Option 1: Only when the L2 U2N Remote UE and L2 U2N Relay UE belong to the same gNB.
Option 2: When the L2 U2N Remote UE and L2 U2N Relay UE belong to the same or different gNBs, for path switch from indirect to direct path, and from direct to indirect path.
Option 3: Only when the two L2 U2N Relay UEs belong to the same gNB.
Option 4: When the source gNB decides to trigger path switching without considering the type of path switch.
Explanation: The service continuity procedure is applicable for various mobility cases, including path switch from indirect to direct path and vice versa when the L2 U2N Remote UE and L2 U2N Relay UE belong to the same or different gNBs. This ensures that service continuity is maintained across different network configurations.
