The present invention discloses a method, an apparatus and a system for processing user identity information in a GPON system. In this case, the method comprises: 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. By virtue of the present invention, overlong user identity information of the ONU/ONT end can be set and managed by the OLT end.
