Unbind a registered connection

The Unbind operation deregisters a connection initiated with the Bind operation and then closes that connection. The unbind PDU initiates the request to close the session, with the response returned in unbind_resp PDU. An unbind request can be initiated by either you or OpenMarket when a connection is no longer needed.
