2.1.2.4. Policy response handling
- Forward the response from Policy to the appropriate child thread - it could be a PCI-ANR child thread (in case of PCI-ANR optimization), or PM child thread (in case of autonomous ANR update by PM child thread).
2.1.2.5. Child Thread Status update handling
Clean up the resources associated with the child thread (including cluster details), and kill the child thread.
2.1.3. Terminating
Upon receiving a terminate request clean up all resources.
- Response from policy is handled by a separate thread.
- When positive acknowledgement is received from the policy the cells in the response are removed from the table and when negative acknowledgement is received the negative_ack count for the cell is increased and updated in the table. When no response is received no changes are made.
- When negative_ack count of a particular cell increases beyond a threshold, it is shifted to another table.

These child threads are spawned for handling PCI optimization primarily, though they may also trigger PCI-ANR joint optimization in some cases. The various states and associated actions are described below.

- Start Policy_rsp timer and wait for Policy response by going to "Wait for Policy Response" state (Section 2.2.6).
