CN-122001895-A - Communication method and device

Abstract

A communication method and a device relate to the technical field of communication and are used for improving the utilization rate of resources and avoiding the waste of the resources. The method comprises the steps that when a first SFU determines that a site is offline, an offline event report message is sent to the MFU, and the offline event report message is used for indicating that the site is offline from the first SFU. And the MFU sends a deletion terminal indication message to the second SFU, wherein the deletion terminal indication message is used for indicating the information of deleting the station. When the site is offline, the source SFU reports the offline event to the MFU in time, and the MFU timely informs other SFUs to delete the site information, so that the resource utilization rate can be improved, and the resource waste is avoided.

Description

Communication method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus. Background In fiber-to-room (Fiber To The Room, FTTR) networking, there may be instances where the terminal is offline. In this case, how FTTR networked devices are handled is not discussed. Disclosure of Invention The embodiment of the application provides a communication method and a communication device, which are used for reducing or avoiding longer service interruption time in the station roaming process. In a first aspect, an embodiment of the present application provides a communication method, where a first sub-optical network unit SFU obtains an association request frame (or a reassociation request frame) from a station, where the association request frame is used for associating the station with the first SFU, and a key used for communication with the station, and the reassociation request frame is used for associating the station with the first SFU. The first SFU sends the association request frame (or reassociation request frame) and the key to the primary optical network unit MFU. Through the scheme, the SFU synchronizes the acquired association request frame and the key to the MFU in the online association stage, so that the association request frame and the key do not need to be acquired again in the roaming stage, the complexity of the roaming switching process is reduced, and the longer service interruption time in the station roaming process is reduced or avoided.
