Question: What happens to associated resources after a successful X2 Removal procedure between two eNodeBs (eNBs) in an E-UTRAN?
Option 1: Associated resources are automatically reallocated to other connections.
Option 2: The decision to release or retain associated resources is left to the discretion of only one eNB.
Option 3: Both eNBs may release all associated resources after removing the X2 signalling connection.
Option 4: Associated resources are put into a dormant state pending further instructions.
Explanation: Upon successful completion of the X2 Removal procedure, as indicated by the X2 REMOVAL RESPONSE message from the receiving eNB, both eNodeBs (eNBs) not only remove the X2 signalling connection but also have the option to release all resources that were associated with this connection. This ensures efficient resource management within the E-UTRAN.
