1. An apparatus for fast handover in an optical multi-cell communication system for use in an access point, the apparatus being configured for:
advertising presence of the access point in an optical multi-cell communication system by transmitting shortened frames without a payload portion in an allocated pre-defined part of a common channel of a frame cycle of a link layer or physical layer protocol, wherein the shortened frame contains an identifier of the advertising access point;
pre-registering an end point,
reserving transmission resources of the access point for the end point, and
transmitting an acceptance message which includes timing information of the reserved transmission resources and an endpoint identifier to the end point, in response to a pre-registration request received from the end point.
