Step S10: the start-stop of next up period of local side apparatus downlink broadcast constantly, comprising time window period that is used to apply for the registration of and the time slot arrangement of distributing to each ustomer premises access equipment.
In this step; Characteristic according to the EOC half-duplex network; Time shaft is divided into the period arrangement that uplink and downlink replace successively; And keeping a segment protect respectively at interval between the up-downgoing, between the ascending time slot of hour of log-on window and ustomer premises access equipment and between the ascending time slot of ustomer premises access equipment, come the sending direction and the transmitting apparatus in a certain moment in the uniform dispatching whole system by local side apparatus.
For example as shown in Figure 4, at first after local side apparatus powers on, total time shaft is divided into the up-downgoing period and replaces five equilibrium.Segment protect then was that segment protect is again that segment protect so circulates at interval when the descending period of 300ms adding 3ms at interval afterwards when the up period of 300ms adding 3ms at interval when the descending period of for example first 300ms was added 3ms.
First time slot arrangement is: the length of the up period that will set deducts the length of the time window period of application for registration, all gives the current ustomer premises access equipment of having accomplished registration according to the sequencing of registration again.If have no registered ustomer premises access equipment to exist, the then next up moment all is used to time window period of applying for the registration of.
Step S11: whether the ustomer premises access equipment that receives broadcasting is registered, if having not yet registered then get into step S12, if registered then get into step S15.
Step S12: unregistered ustomer premises access equipment sends application for registration to local side apparatus at the time window of applying for the registration of in the period.
Furtherly, intercept broadcasting earlier after unregistered ustomer premises access equipment powers on, learning the definite time window that is used to apply for the registration of after the period, the time point that begins from the hour of log-on window at random postpones up again transmission application for registration of a period of time to local side apparatus.This measure is to bump when preventing that a plurality of ustomer premises access equipments from sending application for registration.Ustomer premises access equipment is intercepted downstream message after sending application for registration all the time; If do not receive the response of application for registration in next descending period; Then can be judged as registration timeout, continue up transmission application for registration according to the hour of log-on window period of up-to-date arrangement, till succeeding in registration.
Step S13: local side apparatus carries out the mandate audit of legitimacy to ustomer premises access equipment after receiving application for registration, and the information that audit is accomplished through the descending transmission registration of back local side apparatus is given ustomer premises access equipment.
