FIELD: physics, computer engineering.
SUBSTANCE: invention relates to apparatus for processing user identity information in a GPON system. The method comprises steps of: an optical line terminal OLT determining that a length of a string of user identity information used for an SIP session exceeds a threshold; the optical line terminal OLT constructing an optical network terminal management and control interface OMCI message, wherein the OMCI message carries the user identity information used for the SIP session; the optical line terminal OLT sending the OMCI message to an optical network unit ONU or an optical network terminal ONT; and the optical network unit ONU or the optical network terminal ONT acquiring the user identity information from the OMCI message.
EFFECT: more secure data transmission by changing the extremely long user identity information.
