Then, the agency's processing carried out using line concentrator of Fig. 4~Fig. 6 to embodiment of the present invention 1 is illustrated.
In addition, being illustrated respectively to the lower and higher situation of load of agency's processing.
Fig. 4 be indicate agency processing load it is lower (line concentrator act on behalf of process performance relative to processing load condition
Still have surplus energy) figure of the control flow of Shi Shizhi.As an example, it shows from the access in the coverage area of the next line concentrator 12
Device 31 issues the case where MLD frame.
In the lower situation of load of agency's processing, the agentbased control portion 223 of upper line concentrator 22 is handled from agency
Portion 221, which receives, indicates that the agency of this lower meaning of load of agency's processing handles load condition notice.Then, agentbased control portion
223 send to the agentbased control portion 123 of the next line concentrator 12 without agent advertisement.
It receives and is sent to processing unit 121 is acted on behalf of without agent advertisement without the agentbased control portion 123 of agent advertisement.Agency
Processing unit 121, which is received, handles (becoming closing) without after agent advertisement, then no longer implementing agency.
It in the state of acting on behalf of processing unit 121 to close, is sended over from access mechanism 31 in the next line concentrator 12
MLD frame is handled in acting on behalf of processing unit 121 without agency, and carries out generation by the processing unit 221 of acting on behalf of of upper line concentrator 22
Reason processing.
Filtering settings portion will be sent to by the filtering settings notice of agency's treated MLD frame by acting on behalf of processing unit 221
224。
Filtering settings portion 224 is based on the filtering settings notice received, to filter house 222 and the next line concentrator 12
Filter house 122 is filtered setting.
Carry out agency treated MLD frame is sent to information source 50 by acting on behalf of processing unit 221, information source 50 issue with

MC, which is flowed through, is sent to institute by the filter house 222 of upper line concentrator 22, the filter house 122 of the next line concentrator 12
Desired access mechanism (being access mechanism 31 in the explanation).
In agency's processing lower situation of load as Fig. 4, it is same that the higher situation of load is handled with aftermentioned agency
Sample, it is also considered that agency's processing is distributed in the next line concentrator.However, if will be acted on behalf of when agency's processing load is lower
Processing dispersion also can be from the next line concentrator even if then there is the MC stream dispensed for example in upper line concentrator
The dispatching request for carrying out same MC stream may interfere to act on behalf of the function of script, i.e. efficient frequency band use.In other words, to same
One dispatching request is uniformly processed, this has the advantages that efficiency is higher in the frequency band use aspect that MC flows when dispensing.
Then, agency's processing higher state of load is switched to from the agency shown in Fig. 4 processing lower state of load
When movement be illustrated.
Fig. 5 is the control flow for indicating essence when being switched to higher state from agency's processing lower state of load
Figure.As an example, it is shown below the movement of situation: in addition to sending out from the access mechanism 31 in the coverage area of the next line concentrator 12
Other than the dispatching request sent, MLD frame also is sent from the access mechanism 41 in the coverage area of upper line concentrator 22, due to upper
It is higher that the agency of position line concentrator 22 handles load, therefore agency's processing is made to be transferred to the next line concentrator 12, to disperse to act on behalf of
Handle load.
Firstly, the dispatching request from access mechanism 41 is also generated other than from the dispatching of access mechanism 31 request,
Act on behalf of processing unit 221 received MLD frame become and be more than and the state of the related defined threshold of agency's processing number.
It acts on behalf of processing unit 221 and agency's processing load condition notice is sent to agentbased control portion 223, if agentbased control portion
223, which handle load condition notice according to the agency, is judged as that agency's processing load has been more than threshold value, then to the next line concentrator 12
Agentbased control portion 123 send agency implement notice.
Implement notice to 121 transmission agency of processing unit is acted on behalf of in the agentbased control portion 123 for receiving agency's implementation notice.If generation
Reason processing unit 121 receives agency and implements notice, then agency can be implemented by, which becoming, handles (becoming starting).
Therefore, become capable of implementing by act on behalf of filtering settings notice that processing unit 121 carries out filtering settings portion 124, with
And the filtering settings that filter house 122 and filter house 222 are carried out by filtering settings portion 124.
Then, the movement of following situations is illustrated: that is, shown in fig. 5 from upper line concentrator 22 to the next line concentration
The agency of device 12 handles transfer and completes, and becomes the state that can implement agency's processing by the next line concentrator 12, so that on
Position line concentrator 22 is no longer implemented (closing) and is handled from the agency of the received MLD frame of the next line concentrator 12.
Fig. 6 is the figure for indicating the control flow of the essence in the case where stopping agency's processing of upper line concentrator 22.
That is, showing following movement as the subsequent of the control flow for using Fig. 5 to indicate: agency's processing is transferred from upper line concentrator 22
To the next line concentrator 12, stop the function of acting on behalf of processing unit 221 for the upper line concentrator 22 for originally implementing agency's processing
Only (close).
In the next line concentrator 12 for having started agency's processing, agentbased control portion 123 receives generation from processing unit 121 is acted on behalf of
Reason processing load condition notice.Then, agentbased control portion 123 sends to the agentbased control portion 223 of upper line concentrator 22 and is not necessarily to
Agent advertisement.
It receives and is not necessarily to agent advertisement to the transmission of processing unit 221 is acted on behalf of without the agentbased control portion 223 of agent advertisement.If generation
Reason processing unit 221 receive should without agent advertisement, then no longer implementation by it is in the received MLD frame of upper line concentrator 22, from
The agency of the received MLD frame of the next line concentrator 12 handles (becoming closing).
As described above, will act on behalf of processing be distributed to the next line concentrator 12 from upper line concentrator 22 in the state of, into
Row agency processing.That is, agency's processing of MLD frame transmitted by access mechanism 31 is not carried out by upper line concentrator 22, and under
Position line concentrator 12 carries out, in addition, receiving agency's processing in the next line concentrator 12 and by the filtering of the next line concentrator 12
Configuration part 124 to carry out filtering settings related with the MLD frame to filter house 122 and 222 both sides of filter house.
It is noted herein that not acting on behalf of processing unit 221 to implement the object of agency's processing by (closing) in Fig. 6 is under
The position received MLD frame of line concentrator 12, and to from the received MLD of access mechanism 41 in the coverage area of upper line concentrator 22
Frame implements (opening) agency processing.
That is, the next line concentrator 12 is only to the access in itself coverage area after making agency's processing load
The MLD frame of device 31 carries out agency's processing, and upper line concentrator 22 is only to the access mechanism 41 in itself coverage area
MLD frame carries out agency's processing.
In addition, shown in Fig. 4 traditional thread binding by co-level being converted to from the agency shown in fig. 6 processing scattered state of load
When setting 22 and uniformly carrying out acting on behalf of the state of processing, become following below scheme.
After access mechanism 41 stops sending MLD frame, processing unit 221 is acted on behalf of to agentbased control portion 223 and sends expression agency
The agency of this meaning (lower than this meaning of the second defined threshold related with agency's processing number) of the load reduction of processing is handled
Load condition notice.
Then, agentbased control portion 223 sends to the agentbased control portion 123 of the next line concentrator 12 and is not necessarily to agent advertisement.This
Outside, agentbased control portion 223 sends agency's implementation notice to processing unit 221 is acted on behalf of, to cover model to from the next line concentrator 12
The MLD frame of access mechanism in enclosing is handled.
After as a result, as illustrated by using Fig. 4, agency's processing is uniformly carried out by upper line concentrator 22, by
Filtering settings portion 224 is filtered setting to filter house 222 and filter house 122.
As described above, according to the present embodiment 1, it, can benefit in the communication system that multiple line concentrators are configured to multistage
With multiple line concentrators come control agent processing, therefore there is the load that can disperse agency's processing and can will have same
Process performance line concentrator be applied to large-scale communication system effect.
Also, due to that can be carried out in the case where not carrying out agency's processing to each line concentrator to other line concentrators
Filter setting, therefore have the effect that the load that agency can be inhibited to handle increases, it can not influence as effective use frequency band
In the case where the function of acting on behalf of script, frequency band is effectively utilized.
In addition, can eliminate in previous line concentrator it is generated agency processing repetition, can to agency processing load compared with
