Embodiment

To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention Formula is described in further detail.

For the ease of understanding the technical scheme in the present invention, first below to substantially general involved by technical solution of the present invention Read and be briefly described：

Existing PLC technology standard can include：Worked out by Home Plug alliance (HomePlug alliances) The standards such as HomePlug1.0, HomePlug AV, HomePlug AV2, HomePlug Green PHY, are worked out by ITU-T The standards such as G.hn, G.hnem, by standards, also PRIME such as IEEE IEEE1901, IEEE1901.2, IEEE1905.1 worked out Standard and G3-PLC standards.Access network (the Access of smart grid-oriented application had wherein both been contained in IEEE1901 standards Network) part, also contains towards indoor net (In-Home network) part of indoor broadband application, and In-Home Part further includes being based on Fourier transformation OFDM (FFT OFDM) part and based on small echo OFDM (Wavelet OFDM part).

IEEE1905.1 standards are the household network standards for having merged wired and wireless two kinds of technology, IEEE1905.1 is that different home network technologies define a unified level of abstraction, and defines the control of some level of abstractions Transmitted between message, any equipment that level of abstraction control message can be in whole hybrid network, any IEEE1905.1 equipment Level of abstraction control message can be received and identified out.

ITU-T G.9972 standard (also known as G.cx standards) is directed to coexisting between the different PLC technologies of following four： Access parts in IEEE1901, In-Home parts, the In-Home portions based on Wavelet OFDM based on FFT OFDM Point, G.hn.

G.9972 the co-existence schemes of standard are as follows：

Refer to shown in Figure 1A, it illustrates the ISP that G.9972 standard is distributed by four symbiotic systems in the prior art The schematic diagram of window, wherein ACC, which are represented, to be distributed to the ISP windows of 1901 access systems, is separated by T_ISPIHC1 afterwards is represented and distributed to The ISP windows of 1901FFT OFDM indoor heating systems, IHC2 represents the ISP windows for distributing to 1901Wavelet OFDM indoor heating systems, IH- The time interval that G represents between the ISP windows for distributing to G.hn systems, two neighboring ISP windows is T_ISP。

G.9972 by T_ISP(6 ac periods) is divided into 3 TDMU, and each TDMU is 2 ac periods, each TDMU is subdivided into 8 TDMS again, and the time and position relationship between them, it illustrates in the prior art as shown in Figure 1B G.9972 schematic diagram of the standard to the division of time domain.

Because any symbiotic system can send ISP signals in allocated ISP windows, and other symbiotic systems can be with The ISP signals are monitored in the ISP windows, therefore the species of simultaneous PLC system on power line can be determined therefrom that, i.e., Current network state can be determined, is G.9972 that these symbiotic systems distribute time-domain resource (i.e. by each according to network state TDMS is allocated to different symbiotic systems according to pre-defined rule), the node of co-existin networks is being allocated in every kind of symbiotic system Time-domain resource transmission data.

Shown in Figure 2, it illustrates the schematic diagram of the resource multiplex system provided in one embodiment of the invention.Should Resource multiplex system can include the first symbiotic system A and the second symbiotic system B, the first symbiotic system A and be wrapped including at least one The first co-existin networks 220 containing the first center control nodes 222 and at least one the first ordinary node 224, the second coexistence system System B includes the second center control nodes 242 and the second co-existin networks 240 of at least one the second ordinary node 244, by First co-existin networks 220 in the first symbiotic system A have no effect on this when being multiplexed the second symbiotic system B and first coexisted Another first co-existin networks 220 in system A, therefore other the first co-existin networks are eliminated in Fig. 2, for the ease of description, Only illustrated below by taking one of the first co-existin networks 220 for needing to be multiplexed as an example.

Needed for any one in first in the first co-existin networks 220 of multiplexed resource, first co-existin networks 220 Heart control node 222 sets n detection time domain, the second co-existin networks into the second symbiotic system B in qualified time domain 240 the second center control nodes 242 send solicitation message, and the solicitation message includes the position of n detection time domain Confidence ceases and the first type information for coexisting net system A, and needs into the first co-existin networks 220 n first of multiplexed resource Ordinary node 224, which is sent, indicates message, and the instruction message is carried and the unique corresponding detection time domain of the first ordinary node 224 Positional information.

First ordinary node 224 of first co-existin networks 220, which is received, indicates message, in the institute of the first ordinary node 224 Corresponding detection time domain sends the intersystem protocol ISP signals corresponding to the first symbiotic system A；

Second center control nodes 242 of the second co-existin networks 240 receive solicitation message, to second co-existin networks Each of 240 specifies node to send detecting event request message, and detecting event request message is used to indicate to specify node in n inspection The ISP signals whether tim e- domain detection receives the first symbiotic system A are surveyed, it is any one in the second co-existin networks 240 to specify node There are the second ordinary node 244 and/or the second center control nodes 242 of transmission demand, special time period in special time period For a period of time determined by the second center control nodes 242.

Unless otherwise specified, detecting event request is transmitted between the second center control nodes 242 and the second ordinary node 244 During message, the second center control nodes 242 and the second ordinary node 244 refer both to be located in same second co-existin networks 240 Node.

Each of second co-existin networks 240 specifies node to detect whether tim e- domain detection receives the first coexistence system at n Unite A ISP signals, and the testing result of each detection time domain is sent to this by testing result reporting message and second net coexists Second center control nodes 242 of network 240.

Second center control nodes 242 of the second co-existin networks 240 collect each specified node of the second co-existin networks 240 The testing result reporting message of transmission, obtains the summarized results of each detection time domain, in first into the first co-existin networks 220 Heart control node 222 send carry the summarized results collect notification message.

The remittance that the first center control nodes 222 in first co-existin networks 220 are sent according to the second center control nodes 242 Summarized results in total notification message, determines in the first co-existin networks 220 to send the first of the ISP signals in each detection time domain Whether ordinary node 224 has the authority of the second symbiotic system B of multiplexing resource.

In summary, the resource multiplex system provided in the embodiment of the present invention, coexists by the first symbiotic system first First center control nodes of network set n detection time domain in qualified time domain, and notify first co-existin networks Middle n the first ordinary nodes for needing to be multiplexed detect the ISP signals of time domain the first symbiotic system of transmission at n successively, so as to the The specified node of the second co-existin networks detects whether tim e- domain detection receives the ISP signals, first at this n in two symbiotic systems Center control nodes and then collect whether the first ordinary node of determination there is multiplexing second to coexist according to obtained testing result The authority of the resource of system；Solve in the prior art because the problem of G.9972 standard can not be for network allocation extra resource； If the ISP signals that the first ordinary node is sent in the first co-existin networks are not received by the second symbiotic system, Ye Ji One ordinary node transmission data have no effect on the second symbiotic system, then first ordinary node can be multiplexed the second symbiotic system Resource, having reached can ensure to be located at a kind of node in symbiotic system in co-existin networks when needing extra resource, can be with Multiplexing by the resource of other symbiotic systems of its influence, does not improve the effect of resource utilization.

Referring still to shown in Fig. 2, it can also showing for the resource multiplex system provided in another embodiment of the present invention It is intended to.The resource multiplex system can include the first symbiotic system A and the second symbiotic system B, the first symbiotic system A including at least One includes the first center control nodes 222 and the first co-existin networks 220 of at least one the first ordinary node 224, second Symbiotic system B includes the second center control nodes 242 and the second co-existin networks of at least one the second ordinary node 244 240, due to first co-existin networks 220 in the first symbiotic system A had no effect on when being multiplexed the second symbiotic system B this Another first co-existin networks 220 in one symbiotic system A, therefore other the first co-existin networks are eliminated in Fig. 2, for the ease of Description, is only illustrated by taking one of the first co-existin networks 220 for needing to be multiplexed as an example below.

Needed for any one in first in the first co-existin networks 220 of multiplexed resource, first co-existin networks 220 Heart control node 222 sets n detection time domain in qualified time domain, needs multiplexing to provide into the first co-existin networks 220 N first ordinary nodes 224 in source, which are sent, indicates message, and the instruction message carries unique corresponding with the first ordinary node 224 Detection time domain positional information.

Here the n said value can be the total number of all nodes in the first co-existin networks 220, or save part The number of point.Generally, n value is with needing the first common section of multiplexed resource determined by the first center control nodes 222 The number of point 224 is identical, such as, and the first center control nodes 222 find it when distributing resource for each ordinary node 224 In one or the first ordinary node of part 224 need to take extra resource when larger (such as portfolio than), and the first center When control node can be fewer for the resource of its distribution, then it can determine that these first ordinary nodes 224 have and be multiplexed extra money The demand in source；It will be apparent that the first ordinary node 224 can be sent to the first center control nodes 222 for asking the first center Control node 222 is the allocation request message that the first ordinary node 224 distributes extra resource, corresponding, the first center control section Point 222 then judges whether first ordinary node 224 needs to be multiplexed extra resource according to allocation request message.

First ordinary node 224 of first co-existin networks 220, which is received, indicates message, and sending first in detection time domain coexists Intersystem protocol ISP signals corresponding to system A.

In general, the first center control nodes 222 can (such as notification broadcast or unicast indicate to disappear in several ways Breath or by send carry indicate message beacon frame) come indicate the first ordinary node 224 send ISP signals, the present embodiment This is not restricted.Moreover, after the first ordinary node 224 receives instruction message, can also be controlled to the first center Node 222 is replied for representing to have been received by the confirmation message for indicating message.Whether the confirmation message sends, the present embodiment pair This is not restricted.It should be noted that the instruction message and confirmation message said here are not generally EEE1905.1 level of abstractions Control message, but the control message in the first co-existin networks 220.

In a kind of possible implementation, for each the first predetermined ordinary node 224, the first center control nodes 222 can send to these first ordinary nodes 224 and indicate message respectively, it is each indicate to carry in message one with it is first general The positional information of the logical unique corresponding detection time domain of node 224.In alternatively possible implementation, the first center control section Point 222 can send to these multicasts of the first ordinary node 224 and indicate message, indicate to carry n group corresponding relations in message, often Identification information of the group corresponding relation comprising the first ordinary node 224 and with the unique corresponding detection of first ordinary node 224 The positional information of time domain.

First center control nodes 222 can also be controlled at the second center of the second co-existin networks 240 into the second symbiotic system B Node 242 processed sends solicitation message, and the positional information and first that the solicitation message includes n detection time domain coexists System A type information.

Here the first symbiotic system A said type information represents that first symbiotic system A is G.9972 in standard It is any in four kinds of symbiotic systems, therefore the different ISP signals of different types of symbiotic system correspondence；In addition, detection request The network label that message can also carry the first co-existin networks 220 (is first to coexist i.e. for identifying first co-existin networks 220 Which of system A network), the information such as n values.

Second center control nodes 242 of the second co-existin networks 240 receive solicitation message, to second co-existin networks 240 each second ordinary node 244 specified sends detecting event request message, and detecting event request message refers to for instruction Determine node and detect whether tim e- domain detection receives the first symbiotic system A ISP signals at n, wherein, it is second common to specify node Deposit any one in network 240 has the second ordinary node 244 and/or the control of the second center of transmission demand in special time period Node 242, special time period is a period of time determined by the second center control nodes 242.

As long as that is, any second ordinary node 244 and the control of the second center are saved in the second co-existin networks 240 Point 242 has transmission demand in special time period, then can be used as specified node.

In actual applications, second terminal control node is it is determined that during special time period, can include following three kinds of situations：

In the first scenario, when carrying specified in the solicitation message that the first center control nodes 222 are sent Between section when (the first center control nodes 222 ask to arrange detection time domain within the period, and detect whether to be multiplexed the Two symbiotic system B resource), if the second center control nodes 242 allow the first co-existin networks 220 to specify the period to detect at this Whether second symbiotic system B resource can be multiplexed, then the specified period is defined as specific by the second center control nodes 242 Period；

In the latter case, when carrying specified in the solicitation message that the first center control nodes 222 are sent Between section when, if the second center control nodes 242 do not allow the first co-existin networks 220 this specify period detect whether to answer With the second symbiotic system B resource, the second center control nodes 242 can specify another special time period, and then second Center control nodes 242 notify another special time period to the first center control nodes 222, so that the first center is controlled Node 222 processed manages the first co-existin networks 220 and in another special time period detects whether that the second coexistence system can be multiplexed System B resource.

In a third case, the second center control nodes 242 using the default resource of the second co-existin networks 240 as specific Period.

In actual applications, the second center control nodes 242 of second co-existin networks 240 receive detection request disappear After breath, the first center control nodes 222 that can be into the first co-existin networks 220 reply a detection response message, the inspection Surveying response message is used for the detection for indicating that second center control nodes 242 have received the transmission of the first center control nodes 222 Request message.It will be apparent that second center control nodes 242 are after solicitation message is received, can also judge this Whether two symbiotic system B resource allows to be multiplexed by other symbiotic systems, if the resource permission of the second symbiotic system is other common Deposit system multiplexed resource, then the second center control nodes are carried in detection response message is used to indicate second co-existin networks 240 receive the information of first co-existin networks 220 multiplexing request；Otherwise, then the second center control nodes are detecting response message It is middle to carry for indicating that the second co-existin networks 240 refuse the information of first co-existin networks 220 multiplexing request.Need explanation It is that the solicitation message and detection response message said here are IEEE1905.1 level of abstraction control messages, and detects thing Part request message is then the control message in the second symbiotic system 240, and in actual applications, the second center control nodes 242 Detection response message can not also be replied, the present embodiment is construed as limiting not to this.

Each of second co-existin networks 240 specifies node to detect whether tim e- domain detection receives the first coexistence system at n Unite A ISP signals, and the testing result of each detection time domain is sent to this by testing result reporting message and second net coexists Second center control nodes 242 of network 240.It is worth noting that, when the second center control nodes 242 have in special time period During transmission demand, then the second center control nodes 242 oneself, which also turn into, specifies node, i.e. the second center control nodes 242 itself Be also required in detection time domain to detect the first symbiotic system A ISP signals, and by testing result and other specify the detections of nodes As a result collect together.

In actual applications, each specifies node to detect whether tim e- domain detection can receive first and coexist at n respectively System A ISP signals, can be to the second of the second co-existin networks 240 when often detecting the first symbiotic system A ISP signals Center control nodes 242 send testing result reporting message, and the testing result reporting message is carried in correspondence detection time domain inspection Measure the testing result of the first ISP signals that net system A coexists；It will be apparent that when specified node is not detected in some detection time domain To the first symbiotic system A ISP signals, it can also send and examine to the second center control nodes 242 with the second co-existin networks 240 Result reporting message is surveyed, the testing result reporting message is carried is not detected by the first symbiotic system A's in correspondence detection time domain The testing result of ISP signals.

In summary, the resource multiplexing method provided in the embodiment of the present invention, in first in the first symbiotic system The detection time domain that heart control node is notified sends the ISP signals of the first symbiotic system, so as to the specified section in the second symbiotic system Point detects whether tim e- domain detection receives the ISP signals at this n, and then allows the first center control nodes according to obtaining To testing result collect determine the first ordinary node whether have multiplexing the second symbiotic system resource authority；Solve In the prior art because the problem of G.9972 standard can not be for network allocation extra resource；If first is general in the first co-existin networks Logical node is not received after ISP signals by the second symbiotic system, namely the first ordinary node transmission data have no effect on Second symbiotic system, then first ordinary node can be multiplexed the resource of the second symbiotic system, reached can ensure be located at one The node of co-existin networks in symbiotic system is planted when needing extra resource, can be multiplexed not by other symbiotic systems of its influence Resource, improve the effect of resource utilization.

Shown in Figure 19, it illustrates the method stream of the resource multiplexing method provided in further embodiment of the present invention Cheng Tu.Main the second center with the second co-existin networks of one of them applied to system shown in Figure 2 240 of the resource multiplexing method It is illustrated in control node 242.The resource multiplexing method can include：

1901, the detection request for receiving the first center control nodes transmission of the first co-existin networks in the first symbiotic system disappears Breath, solicitation message includes the type information of the n positional information for detecting time domain and the first symbiotic system；

1902, specify node to send detecting event request message to each of the second co-existin networks, detecting event request disappears Cease for indicating to specify node to detect whether tim e- domain detection receives the ISP signals of the first symbiotic system at n, so that each is specified Node detects whether tim e- domain detection receives the ISP signals of the first symbiotic system at n, and by the detection knot of each detection time domain Fruit gives the second center control nodes by testing result reporting message；

Here the specified node said has transmission demand for any one in the second co-existin networks in special time period The second ordinary node and/or the second center control nodes, special time period is determined by the second center control nodes one section Time；Here the ISP signals said are that the first center control nodes need n first of multiplexed resource into the first co-existin networks Ordinary node, which is sent, indicates message, indicates that message carries the positional information with the unique corresponding detection time domain of the first ordinary node When, the ISP signals of the first symbiotic system sent by the first ordinary node in detection time domain.

1903, collect each testing result reporting message for specifying node to send, obtain each detection time domain collects knot Really；

1904, the notice that collects that the first center control nodes transmission into the first co-existin networks carries summarized results disappears Breath, so as to summarized results of first center control nodes in summarized results notification message, it is determined that in each detection time domain hair Send whether the first ordinary node of ISP signals has the authority for the resource for being multiplexed the second symbiotic system.

In summary, the resource multiplexing method provided in the embodiment of the present invention, by the way that in the first symbiotic system first is total to Deposit network the first center control nodes send n detection zone notify to the specified node in the second symbiotic system, so as to Specify node to detect whether tim e- domain detection receives the ISP signals of the first symbiotic system at this n, and then cause the control of the first center Node processed determines whether the first ordinary node has the money for being multiplexed the second symbiotic system according to collecting for the testing result to obtaining The authority in source；Solve in the prior art because the problem of G.9972 standard can not be for network allocation extra resource；If first The first ordinary node is not received after ISP signals by the second symbiotic system in co-existin networks, namely the first ordinary node Transmission data have no effect on the second symbiotic system, then first ordinary node can be multiplexed the resource of the second symbiotic system, reach It can ensure that the node for being located at co-existin networks in a kind of symbiotic system, when needing extra resource, can be multiplexed not by its shadow The resource of other loud symbiotic systems, improves the effect of resource utilization.

Shown in Figure 20, it illustrates the method stream of the resource multiplexing method provided in a still further embodiment of the present invention Cheng Tu.The resource multiplexing method is main common with the second of the second co-existin networks of one of them applied to system shown in Figure 2 240 It is illustrated in node 244.The resource multiplexing method can include：

2001, the detecting event request message that the second center control nodes of the second co-existin networks are sent is received, thing is detected Part request message is used to indicate to specify node to detect whether tim e- domain detection receives the ISP signals of the first symbiotic system at n；

Node is specified to have the second common section of transmission demand in special time period for any one in the second co-existin networks Point and/or the second center control nodes, special time period are a period of time determined by the second center control nodes.

ISP signals are the first center control nodes of the first co-existin networks in the first symbiotic system into the first co-existin networks Need n the first ordinary nodes of multiplexed resource to send and indicate message, indicate that message is carried uniquely right with the first ordinary node The positional information for the detection time domain answered, the ISP signals of the first symbiotic system sent by the first ordinary node in detection time domain.

2002, detect whether tim e- domain detection receives ISP signals at n；

2003, the testing result of each obtained detection time domain is sent to the second center by testing result reporting message Control node, so that each testing result for specifying node to send that the second center control nodes collect the second co-existin networks is reported Message, obtains the summarized results of each detection time domain, and carry to the first center control nodes transmission of the first co-existin networks Summarized results collects notification message, so that the first center control nodes are according to the summarized results collected in notification message, it is determined that Whether the first ordinary node for sending ISP signals in each detection time domain in the first co-existin networks has the second symbiotic system of multiplexing Resource authority.

Here the specified node said has transmission demand for any one in the second co-existin networks in special time period Second ordinary node and/or the second center control nodes, when special time period is one section determined by the second center control nodes Between.

In summary, the resource multiplexing method provided in the embodiment of the present invention, is sent out by receiving the second center control nodes The n detection zone and the type of the first symbiotic system sent, detect whether tim e- domain detection receives the first coexistence system at this n The ISP signals of system, and then cause the first center control nodes to collect the commonly section of determination first according to the testing result to obtaining Whether point has the authority of the resource of the second symbiotic system of multiplexing；Solve in the prior art because G.9972 standard can not be network The problem of distributing extra resource；If the first ordinary node is not total to after ISP signals by second in the first co-existin networks Deposit system is received, namely the first ordinary node transmission data have no effect on the second symbiotic system, then first ordinary node can To be multiplexed the resource of the second symbiotic system, reach the node that can ensure to be located at co-existin networks in a kind of symbiotic system in needs During extra resource, it can be multiplexed not by the resource of other symbiotic systems of its influence, improve the effect of resource utilization.

Refer to shown in Figure 21 A, it illustrates the method for the resource multiplexing method provided in another embodiment of the invention Flow chart.The resource multiplexing method is main with applied to being illustrated in system shown in Figure 2.Due in the first symbiotic system First co-existin networks had no effect on when being multiplexed the second symbiotic system in first symbiotic system another first be total to Network is deposited, therefore for the ease of description, is only illustrated below by taking one of the first co-existin networks for needing to be multiplexed as an example.Should Resource multiplexing method can include：

2101, the first center control nodes set n detection time domain in qualified time domain；

Here the n said value can be the total number of all nodes in the first co-existin networks, or part of nodes Number.Generally, of first ordinary node of the n value with needing multiplexed resource determined by the first center control nodes Number is identical, such as, and the first center control nodes find that one of them or part are common when distributing resource for each ordinary node The portfolio of node is than larger, and the first center control nodes can then determine these when can be fewer for the resource of its distribution First ordinary node has the demand for being multiplexed extra resource；It will be apparent that the first ordinary node can be to the first center control nodes Send for asking the first center control nodes to be the distribution request that the first ordinary node distributes extra resource, it is corresponding, first Center control nodes then judge whether message judges first ordinary node according to allocation request message.

In a kind of possible implementation, the duration of each detection time domain can be an ISP domain in G.9972 standard Length.

In actual applications, because the standard being based on is different, qualified time domain can have a variety of different selections, It can specifically include：

In the case of the first, qualified time domain, when meeting the first Rule of judgment, is the first symbiotic system A acquiescence Time-domain resource；

In the case of second, qualified time domain, when meeting the second Rule of judgment, is the first symbiotic system A extension ISP windows；

In the case of the third, qualified time domain, when meeting the second Rule of judgment, is the first symbiotic system A extension The acquiescence time-domain resource of ISP windows and the first symbiotic system A；

In the first case described above, refer to shown in Figure 21 B, it illustrates provided in section Example of the present invention A kind of schematic diagram of qualified time domain, the first symbiotic system is G.hn systems, and the second symbiotic system is that EEE1901 accesses system System, the ISP windows G.9972 set for G.hn systems are IH-G, are that the ISP windows that EEE1901 access systems are set are ACC, then first The available TDMS of symbiotic system be TDMS0, TDMS1, TDMS2 and TDMS7, the available TDMS of the second symbiotic system be TDMS3, TDMS4, TDMS5 and TDMS6, now the first center control nodes in the first co-existin networks then can TDMS0, TDMS1, N detection time domain is set on TDMS2 and TDMS7.These n detection time domain can be adjacent time domain, or non-conterminous Time domain.

In the case of above-mentioned second,

Refer to shown in Figure 21 C, it illustrates second of the qualified time domain provided in section Example of the present invention Schematic diagram, the first symbiotic system be G.hn systems, the second symbiotic system be EEE1901 access systems, be G.9972 G.hn systems The ISP windows that system is set are IH-G, are that the ISP windows that EEE1901 access systems are set are ACC, then the first symbiotic system is available TDMS be TDMS0, TDMS1, TDMS2 and TDMS7, the available TDMS of the second symbiotic system be TDMS3, TDMS4, TDMS5 and TDMS6, now the first center control nodes in the first co-existin networks then can ISP windows IH-G and TDMS0, TDMS1, N detection time domain is set on TDMS2 and TDMS7.These n detection time domain can be adjacent time domain, or non-conterminous Time domain.

In the case of the third, referred to above-mentioned shown in Figure 21 D, it illustrates provided in section Example of the present invention The schematic diagram of three kinds of qualified time domains, the first symbiotic system is G.hn systems, and the second symbiotic system is that EEE1901 accesses system System, the ISP windows G.9972 set for G.hn systems are IH-G, are that the ISP windows that EEE1901 access systems are set are ACC, then first The available TDMS of symbiotic system be TDMS0, TDMS1, TDMS2 and TDMS7, the available TDMS of the second symbiotic system be TDMS3, TDMS4, TDMS5 and TDMS6, now the first center control nodes in the first co-existin networks then can in ISP windows IH-G and (expansible time domain can take one behind ISP windows IH-G to expansible time domain behind adjacent with ISP windows IH-G here A part in TDMS, TDMS or multiple TDMS etc.) on set n to detect time domain.These n detection time domain generally can be with For adjacent time domain.

Above-mentioned in the case of the third, above-mentioned n value can also be set by following three kinds of modes, be respectively：

First way, for any symbiotic system, n values are a fixed value；

The second way, for some symbiotic system, n values are a fixed value, when for different symbiotic systems, n Value can be different；

The third mode, for any symbiotic system, n values can dynamically be set.

2102, the first center control nodes send detection request to the second center control nodes of the second co-existin networks and disappeared Breath, solicitation message carries the type information of this n positional information for detecting time domain and the first symbiotic system；

Here the type information for the first symbiotic system said represents that first co-existin networks are G.9972 four in standard Plant any in symbiotic system, therefore the different ISP signals of different types of symbiotic system correspondence, i.e. ISP signals can be only The type of one mark symbiotic system；In addition, the network label that solicitation message can also include the first co-existin networks (is used for Unique mark first co-existin networks are which of the first symbiotic system co-existin networks), the information such as n values.

Generally, the first co-existin networks select to send solicitation message to which or which other symbiotic systems, lead to Be often dependant on the first co-existin networks want be multiplexed which other symbiotic system in resource, therefore the first co-existin networks can to appoint One the second symbiotic system (non-first symbiotic system) finds multiplexed resource.For example, the first co-existin networks can simultaneously to Other all symbiotic systems (above-mentioned second symbiotic system is one in these symbiotic systems) send above-mentioned detection request and disappeared Breath；Above-mentioned solicitation message can also be sent to other each symbiotic systems successively, when the reusable resource of application is met When first co-existin networks are multiplexed, then stop finding reusable resource to other remaining symbiotic systems, it is reusable when application When resource can not still meet the multiplexing of the first co-existin networks, then continue to find reusable resource to next symbiotic system.

It should be added that, (1) if the first co-existin networks be since the ISP windows of the first co-existin networks when N is set in domain and detects time domain, when n value is the first setting means described by step 2101, by n values are for institute It is a fixed value to have for symbiotic system, therefore the second symbiotic system can learn the n values, namely the second symbiotic system can To learn the n detection time domain since the ISP windows of the first symbiotic system in advance, also therefore the first Centroid is sending inspection This n detection time domain can not be carried when surveying request message.(2) if the first co-existin networks are the ISP from the first symbiotic system N is set in the time domain that window starts and detects time domain, when n value is second of setting means described by step 2101, Because n values are a fixed value for the first co-existin networks, therefore, the first center control nodes are for the first time to the second center Control node, which is sent, can carry this n detection time domain in solicitation message, and subsequently in the first center control nodes to the Two center control nodes are sent can be without carrying this n detection time domain in solicitation message.

2103, the first center control nodes send to predetermined n the first ordinary nodes and indicate message, indicate that message is carried There is the positional information with the unique corresponding detection time domain of the first ordinary node；

The instruction message is used to indicate the first ordinary node for receiving the instruction message entrained by the instruction message Detect that time domain sends the ISP signals of the first symbiotic system.

In a kind of possible implementation, for each the first predetermined ordinary node, the first center control nodes can Message is indicated to be sent respectively to these first ordinary nodes, it is each to indicate to carry one in message with the first ordinary node only The positional information of one corresponding detection time domain.In alternatively possible implementation, the first center control nodes can be to this A little first ordinary node multicasts, which are sent, indicates message, indicates to carry n group corresponding relations in message, and every group of corresponding relation includes the The identification information of one ordinary node and the positional information with the unique corresponding detection time domain of first ordinary node.

2104, the first ordinary node receives the instruction message that the first center control nodes are sent；

In general, the first center control nodes can (such as notification broadcast or unicast indicate message in several ways Or by send carry indicate message beacon frame) come indicate the first ordinary node send the first symbiotic system ISP signals, The present embodiment is not restricted to this.Moreover, after the first ordinary node receives instruction message, can also be to the first center Control node is replied for representing to have been received by the confirmation message for indicating message.Whether the confirmation message sends, the present embodiment This is not restricted.It should be noted that the instruction message and confirmation message said here are not generally IEEE1905.1's Level of abstraction control message, but the control message in the first co-existin networks.

2105, the second center control nodes receive the solicitation message；

In actual applications, the second center control nodes can coexist after solicitation message is received to first The first center control nodes in network reply a detection response message, and the detection response message is used to indicate the control of the second center Node processed have received the solicitation message of the first center control nodes transmission.It will be apparent that the second center control nodes are connecing Receive after solicitation message, can also judge whether to allow in the second symbiotic system by other symbiotic system multiplexed resources, If the resource of the second symbiotic system allows by other symbiotic system multiplexed resources, the second center control nodes are in detection response Carried in message for indicating that the second symbiotic system receives the information of first co-existin networks multiplexing request；Otherwise, then in second Heart control node is carried in detection response message for indicating that the second co-existin networks refuse first co-existin networks multiplexing request Information.It should be noted that the solicitation message said here and detection response message are IEEE1905.1 level of abstractions Control message, and in actual applications, the second center control nodes can not also reply detection response message, and the present embodiment is not This is construed as limiting.

2106, the second center control nodes specify node to send detecting event request message to each；

As long as that is, any second ordinary node and the second center control nodes are in spy in the second co-existin networks There is transmission demand in section of fixing time, then can be used as specified node.

In the first scenario, when the first center control nodes send solicitation message in carry the specified period When (the first center control nodes request arrangement detection time domain within the period, and detect whether that can be multiplexed second coexists The resource of system), if the second center control nodes allow the first co-existin networks to specify the period to detect whether to be multiplexed at this The resource of second symbiotic system, then the second center control nodes by this specify period be defined as special time period；

In the latter case, when the first center control nodes send solicitation message in carry the specified period When, if the second center control nodes do not allow the first co-existin networks to specify the period to detect whether that can be multiplexed second coexists at this The resource of system, the second center control nodes can specify another special time period, and then the second center control nodes will Another special time period is notified to the first center control nodes, so that net coexists in the first center control nodes management first Network in another special time period detects whether that the resource of the second symbiotic system can be multiplexed.

In a third case, the second center control nodes regard the default resource of the first co-existin networks as special time Section.

For the ease of description, any one in the second co-existin networks only had into transmission in special time period in the present embodiment Second ordinary node of demand is used as specified node 242.

Here the detecting event request message said is used to indicate to specify whether node detects tim e- domain detection at above-mentioned n Receive the ISP signals of the first symbiotic system.

Generally, the second center control nodes receive the first center control nodes transmission solicitation message after, A detecting event request message can be generated, would generally carry in solicitation message and carry in the detecting event request message N detection time domain positional information and the first symbiotic system type information, for indicate specify node this n detect Whether tim e- domain detection receives the ISP signals of the first symbiotic system.Second center control nodes individually can specify section to each Point sends detecting event request message, to each node broadcasts can also be specified to send the detecting event request message, here not It is restricted.

In general, the second center control nodes are phases in the detecting event request message for specifying node to send to each With, detecting event request message is usually the control message in the second symbiotic system.

2107, specify node to receive the detecting event request message that the second center control nodes are sent；

Node is specified after the detecting event request message of the second center control nodes transmission is received, it will usually parse The detecting event request message with obtain n detection time domain positional information and the first symbiotic system type information, so as to In this n detect tim e- domain detection whether can receive the ISP signals of the first symbiotic system.

2108, the first ordinary node sends the ISP signals of the first symbiotic system in detection time domain；

After step 2104, the first ordinary node can parse detection corresponding with first ordinary node in instruction message Time domain, and send the ISP signals of the first symbiotic system in the detection time domain.

2109, specify node to detect whether tim e- domain detection receives the ISP signals of the first symbiotic system at this n；

For each detection time domain, each specified node can be detected whether the detection time domain receives the first coexistence system The ISP signals of system.That is, each specified node can obtain tying with the unique corresponding n detection of n detection time domain respectively Really, for each detection time domain, its corresponding testing result can include：The first symbiotic system is received in the detection time domain ISP signals and the ISP signals of the first symbiotic system are not received in the detection time domain.

2110, specify node to be sent to the testing result of each obtained detection time domain by testing result reporting message Second center control nodes；

In actual applications, each specifies node to detect whether tim e- domain detection can receive first and coexist at n respectively The ISP signals of system, when often detecting the ISP signals of the first symbiotic system, can send to the second center control nodes and examine Result reporting message is surveyed, the testing result reporting message is used to indicate in correspondence monitoring tim e- domain detection to the first symbiotic system The testing result of ISP signals；It will be apparent that when the ISP letters for specifying node to be not detected by the first symbiotic system in some detection time domain Number, testing result reporting message can also be sent to the second center control nodes, the testing result reporting message is used to indicate Correspondence monitoring time domain is not detected by the testing result of the ISP signals of the first symbiotic system.

In a kind of possible implementation, node is specified after detecting event request message is received, can be to the Two center control nodes, which are sent, carries the detection for specifying node in detecting event response message, the detecting event response message As a result, it is obvious that detection of the node when detecting tim e- domain detection for one can be specified in the detecting event response message comprising this As a result, testing result of the node when detecting tim e- domain detection for all n can also be specified comprising this.

It should be added that, the detecting event request message and detecting event response message said here generally may be used Think the control message in the second co-existin networks, rather than IEEE1905.1 level of abstraction control messages.

2111, the second center control nodes collect the testing result reporting message that each specifies node to send, and obtain each Detect the summarized results of time domain；

It is worth noting that, when the second center control nodes have transmission demand in special time period, then the second center Control node oneself, which also turns into, specifies node, i.e. the second center control nodes itself to be also required to detect that first is total in detection time domain The ISP signals of deposit system, and the testing result of testing result and other specified nodes is collected together.

In a kind of possible implementation, the rule that collects of the second center control nodes can be as follows：

For each detection time domain, if at least one in the second co-existin networks specifies the testing result of node to be in the detection ISP signal of the tim e- domain detection to the first symbiotic system, it is determined that summarized results is second co-existin networks in the detection time domain Detect the first co-existin networks；

For each detection time domain, if each in the second co-existin networks specifies the testing result of node to be not in the detection ISP signal of the tim e- domain detection to the first symbiotic system, it is determined that summarized results be second co-existin networks detection time domain on not Detect the first co-existin networks.

2112, the second center control nodes are sent to the first center control nodes to be carried each detection time domain and collects knot Fruit collects notification message；

It is usually IEEE1905.1 level of abstraction control messages that this, which collects notification message, and this, which collects notification message, can include the The type (i.e. the second symbiotic system is any in four kinds of symbiotic systems) of two symbiotic systems, the network mark of the second co-existin networks Number (i.e. the second co-existin networks are which co-existin networks of the second symbiotic system), the testing result in each detection time domain Deng.

2113, the first center control nodes receive this and collect notification message；

In a kind of possible implementation, the first center control nodes are receiving the transmission of the second center control nodes Collect after notification message, can also be replied to the second center control nodes and collect confirmation message, to indicate that the first center is controlled Node is successfully received this and collects notification message.

It should be noted that collecting notification message and collecting confirmation message for being said here is usually IEEE1905.1 abstract Layer control message.

2114, the first center control nodes are according to collecting that the second center control nodes of each the second co-existin networks are sent Summarized results in notification message, determines that send ISP signals in each detection time domain in the first co-existin networks first commonly saves Whether point has the authority of the resource of the second symbiotic system of multiplexing.

When there are second co-existin networks in the second symbiotic system, the first center control nodes are it is determined that first is common Node whether have multiplexing the second symbiotic system resource authority when rule can be as follows：

First, for each detection time domain, when the summarized results of the second center control nodes of the second co-existin networks is the Two co-existin networks detect the first symbiotic system in the detection time domain, it is determined that send the first symbiotic system in the detection time domain ISP signals the first ordinary node without multiplexing the second symbiotic system resource authority；

Second, for each detection time domain, when the summarized results of the second center control nodes of the second co-existin networks is Second co-existin networks are not detected by the first symbiotic system in detection time domain, it is determined that send the of ISP signals in detection time domain One ordinary node has the authority of the resource of the second symbiotic system of multiplexing.

First, for each detection time domain, when the second center of at least one the second co-existin networks in the second symbiotic system The summarized results of control node is that the second co-existin networks detect the first symbiotic system in the detection time domain, it is determined that in the inspection Survey power of first ordinary node without the resource for being multiplexed the second symbiotic system that time domain sends the ISP signals of the first symbiotic system Limit；

That is, for each detection time domain, if any one second co-existin networks in the second symbiotic system At least one specify node to receive the ISP signals of the first symbiotic system in the detection time domain, then show in the detection time domain Send the authority of resource of first ordinary node without the second symbiotic system of multiplexing of the ISP signals.

Second, for each detection time domain, when the second center control of each the second co-existin networks in the second symbiotic system The summarized results of node is that the second co-existin networks are not detected by the first symbiotic system in the detection time domain, it is determined that in the inspection Survey the authority that time domain sends resource of first ordinary node with the second symbiotic system of multiplexing of ISP signals.

That is, for it is each detection time domain for, if in the second symbiotic system each second co-existin networks institute There is specified node not receive the ISP signals of the first symbiotic system in the detection time domain, then show to send in the detection time domain First ordinary node of the ISP signals has the authority of the resource of the second symbiotic system of multiplexing.

For example, refer to shown in Figure 21 E, it illustrates two provided in one embodiment of the invention kind coexistence of systems When topological schematic diagram, both systems are respectively to include section in HomePlug systems and G.hn systems, HomePlug systems Point A, B and C, G.hn system only one co-existin networks, the line that the co-existin networks include in node D, E and F, Figure 21 E are represented The node at line two ends is in mutual communication range.It follows that when node A is in some detection time domain transmission HomePlug systems During the ISP signals of system, node D, E and F in G.hn systems will not receive the ISP signals in the detection time domain, also therefore Node A can be multiplexed the time domain that node D, E and F are distributed in G.hn systems, such as node A can be multiplexed with node D distribution Time domain, namely node A and node D can send data in the time domain distributed for node D simultaneously, and mutual transmission will not be to right Side is interfered.Similarly, node B can also be multiplexed the time domain that node D, E and F are distributed in G.hn systems.And because node C exists When detecting that time domain sends the ISP signals of HomePlug systems, it can be listened to by the node D in G.hn systems, therefore node C is not Resource in reusable G.hn systems.Because the time between the two neighboring ISP windows of same symbiotic system is mutually divided into T_H= 4·T_ISP, i.e., 24 ac periods.If above-mentioned qualified time domain for since the ISP windows of the first co-existin networks can Time domain is extended, then when the topology and interference noise environment in the first co-existin networks and (or) the second symbiotic system are changed When, because the first co-existin networks in the upper multiplexed resource once found have not been suitable for current environment, then first net coexists Network needs to find multiplexed resource again, is that this first symbiotic system needs to wait the arrival of next qualified time domain, i.e., Wait the arrival of next expansible time domain since the ISP windows of the first co-existin networks.This stand-by period up to 24 Ac period.In order to reduce the stand-by period for finding multiplexed resource next time as far as possible, it can be distributed for the first co-existin networks Acquiescence time-domain resource (the i.e. above-mentioned qualified time domain of one of which) on reset n detection time domain, to start as early as possible The process of multiplexed resource is found next time.

Supplementary notes are also needed to, because the present embodiment is based on IEEE1905.1 standard implementations (i.e. the first center Control node and the second center control nodes are IEEE1905.1 equipment, namely to be respectively provided with IEEE1905.1 abstract for these nodes Layer, each node can send and receive IEEE1905.1 level of abstractions control message), thus it is above-mentioned in the first center control section The solicitation message that is transmitted between point and the second center control nodes, response message is detected, collects notification message and typically may be used Think EEE1905.1 level of abstraction control message, and the finger sent between the first center control nodes and the first ordinary node It is then the control message in the first co-existin networks to show message, is sent between the second center control nodes and the second ordinary node Testing result reporting message is the control message in the second symbiotic system.

First co-existin networks in supplementary notes, the first symbiotic system are also needed to when finding resource multiplex, The different co-existin networks having no effect in another first co-existin networks searching resource multiplex, namely the first symbiotic system are being found Resource multiplex is separate.For example, the first symbiotic system is G.hn systems, there is 2 G.hn nets under this G.hn system Network, is G.hn networks 1 and G.hn networks 2 respectively, then whether G.hn networks 1 need to find multiplexed resource and G.hn for present networks It is all by the decision of the Independent Decisiveness of G.hn networks 1, and G.hn networks 2 that when network 1, which starts to find multiplexed resource for present networks, It is unrelated.

Supplementary notes are also needed to, when first co-existin networks are finding the resource multiplex of the second symbiotic system, It is required that all second co-existin networks (can include a co-existin networks or multiple co-existin networks) are equal in the second symbiotic system Determine whether to detect first symbiotic system, if in the second symbiotic system all second co-existin networks be not detected by this One symbiotic system, then show that the first co-existin networks in first symbiotic system can be multiplexed the resource of the second symbiotic system.Very Obviously, the second symbiotic system is the symbiotic system for being used to find multiplexed resource that the first co-existin networks are chosen, if second coexists Network also wants to be multiplexed the resource of other symbiotic systems, can also find multiplexing money to other symbiotic systems through the above way Source.Such as, the second co-existin networks can seek multiplexed resource to other all or selected symbiotic systems simultaneously；Also such as, may be used To seek multiplexed resource to other all or selected symbiotic systems successively, when the multiplexed resource sought is available for the second co-existin networks In use, then stopping finding multiplexed resource to remaining symbiotic system.

Supplementary notes are also needed to, for same detection time domain, step 2108 and step 2109 are typically to enter simultaneously It is capable, but step 2103,2104 and step 2102 between 2107 then without strict sequencing.

In summary, the resource multiplexing method provided in the embodiment of the present invention, coexists by the first symbiotic system first First center control nodes of network set n detection time domain in qualified time domain, and notify first co-existin networks Middle n the first ordinary nodes for needing to be multiplexed detect the ISP signals of time domain the first symbiotic system of transmission at n successively, so as to the The specified node of the second co-existin networks detects whether tim e- domain detection receives the ISP signals, first at this n in two symbiotic systems Center control nodes so according to the testing result to obtaining collect determination the first ordinary node whether have multiplexing second be total to The authority of the resource of deposit system；Solve in the prior art because G.9972 standard can not asking for the extra resource of network allocation Topic；If the first ordinary node is not received after ISP signals by the second symbiotic system in the first co-existin networks, Ye Ji One ordinary node transmission data have no effect on the second symbiotic system, then first ordinary node can be multiplexed the second symbiotic system Resource, the node for being located at co-existin networks in a kind of symbiotic system can be ensured when needing extra resource by having reached, Ke Yifu With not by its influence other symbiotic systems resource, improve the effect of resource utilization.
