Method and apparatus for controlling an optical network unit to restart upon completion of downloading new software

摘要

The invention provides a method and apparatus for controlling an optical network unit to restart upon completion of downloading new software. Upon completion of downloading a new software version, an optical network terminal firstly determines a type of an active image request to be transmitted based upon stored values, of a RstDelayTimeRange attribute and of a RstDelayTrafficThreshold attribute, corresponding to the optical network unit, and then transmits the active image request to the optical network unit. The determined active image request may be a first active image request to instruct the optical network unit to immediately restart and activate the new software version that has been downloaded, or may be a second active image request to instruct the optical network unit to set an activation flag and a third active image request to instruct the optical network unit to immediately restart, both of which are used in combination.

主权项

1. A method, in an optical line terminal of an optical communication network, of instructing an optical network unit to restart, the method comprising:
upon completion of downloading a new software version, determining a type of an active image request to be transmitted to the optical network unit based upon stored values of a RstDelayTimeRange attribute and of a RstDelayTrafficThreshold attribute corresponding to the optical network unit, wherein, the determining the type of the active image request to be transmitted includes determining whether to transmit one of,
a first active image request that includes an instruction to the optical network unit to immediately restart and activate the new software version upon immediately restarting,a second active image request that includes an instruction to the optical network unit to activate the new software version upon a next time of restarting of the optical network unit, such that the optical network unit refrains from restarting until an instruction to restart is transmitted to the optical network unit from the optical line terminal, ora third active image request that includes an instruction to the optical network unit to immediately restart, the RstDelayTimeRange attribute is used for indicating a time range or a time value in or at which a traffic detection is performed on the optical network unit, and the RstDelayTrafficThreshold attribute is used for indicating an upper traffic limit below or at which the optical network unit is determined to be in a silent state; and transmitting the determined first active image request, second active image request, or third active image request to the optical network unit.
