Abstract
The invention discloses a method, central coordinator, station and system for power line communication network networking and belongs to the technical field of a communication technology. The method includes the steps that a central beacon of a neighbor network within a preset period of time is intercepted; if the central beacon of the neighbor network is intercepted successfully within the preset period of time, a common area of a communication network and the neighbor network is confirmed according to the central beacon of the neighbor network; in the common area, a multi-network coordination indication message in prior to the networking is broadcast so that the station (STA) receiving the multi-network coordination indication message in prior to the networking can stop clustering behaviors; after network coordination is finished, the central beacon is sent so that the STA receiving the central beacon can carry out the networking according to the central beacon. Due to the fact that before the central coordinator sends the central beacon for the networking, the multi-network coordination indication message in prior to the networking is broadcast, and the station receiving the message stops the clustering behaviors so that the phenomenon that neighbor network coordination is carried out on the central coordinator by the station to cause interference can be avoided. The efficiency of the power line communication network networking is improved.

Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment one
Present embodiments provide a kind of method of power line communication network networking, see Fig. 1, the method flow that the present embodiment provides is specific as follows:
101: the central beacon of intercepting neighbor networks in preset time period;
102: if listen to the central beacon of neighbor networks in preset time period, then determine the common area with neighbor networks according to the central beacon of neighbor networks;
103: before common area broadcast networking, Multi net voting coordinates instruction message, the STA (Station, website) that before making to receive networking, Multi net voting coordinates instruction message stops cluster rows to be;
104: after completing the network coordination, send central beacon, make the STA receiving central beacon carry out networking according to central beacon.
Present embodiments provide the method for another kind of power line communication network networking, see Fig. 2, the method flow that the present embodiment provides is specific as follows:
201: intercept the networking that CCO (Central Coordinator, central coordinator, i.e. concentrator) broadcasts in preset time period before, Multi net voting coordinates instruction message;
202: if Multi net voting coordinates instruction message listen to networking in preset time period before, then stopping cluster rows is, and after the central beacon receiving CCO transmission, carries out networking according to central beacon;
Wherein, preset time period is greater than CCO intercepts time of the central beacon of neighbor networks, CCO broadcasts central beacon time and reception and processes the summation of the time of central beacon.
The method that the present embodiment provides, by concentrator before the central beacon of transmission carries out networking, before broadcast networking, Multi net voting coordinates instruction message, the website making to receive this message stops cluster rows to be, carry out neighbor networks to avoid website to concentrator to coordinate to cause interference, improve power line communication network networking efficiency.
In order to clearly set forth the method for a kind of power line communication network networking that above-described embodiment provides, in conjunction with the content of above-described embodiment, for following embodiment two, a kind of method of power line communication network networking is described in detail, refers to following embodiment two:
Embodiment two
Present embodiments provide a kind of method of power line communication network networking, see Fig. 3, the method flow that the present embodiment provides is specific as follows:
301:CCO intercepts the central beacon of neighbor networks in preset time period, if listen to the central beacon of neighbor networks in preset time period, then perform step 302, if do not listen to the central beacon of neighbor networks in preset time period, then perform step 304;
For this step, due to multiple CCO may be comprised in power line communication network, when at least two CCO work simultaneously, between at least two CCO, mutual interference may be there is.In order to avoid the mutual interference between at least two CCO, after the power-up, CCO needs the central beacon of intercepting neighbor networks in preset time period.If listen to the central beacon of neighbor networks in preset time period, then illustrate except this CCO, also have CCO and the network thereof of neighbor networks, now this CCO needs the network coordination carrying out step 302 and step 303 at the common area of this CCO and neighbor networks, interferes with each other to avoid causing between this CCO and CCO of neighbor networks; If do not listen to the central beacon of neighbor networks in preset time period, then the CCO that there is not mutually interference is described, now this CCO directly sends central beacon and starts networking.
The present embodiment does not limit the concrete timing device of the central beacon of intercepting neighbor networks, includes but not limited to, the beacon listen timer in CCO.The present embodiment does not also limit the concrete set-up mode of preset time period of central beacon and numerical value of intercepting neighbor networks.Such as, the time of the beacon listen timer in CCO is set, makes CCO within the time period of this beacon listen set timer, intercept the central beacon of neighbor networks.
In addition, the present embodiment also misaligns the particular content of entreating beacon package to contain and limits, the central beacon that CCO sends at least comprises SNID (the Short Network Identity of neighbor networks, short network identity), MAC (Media Access Control, medium access control) information and the partition information of beacon period, in addition, other network resource scheduling information can also be comprised.
302:CCO determines the common area with neighbor networks according to the central beacon of neighbor networks;
For this step, the present embodiment is not determined to limit with the concrete mode of the common area of neighbor networks according to the central beacon of neighbor networks to CCO.Such as, owing at least comprising the partition information of beacon period in the central beacon of neighbor networks, therefore, CCO determines the common area original position with neighbor networks according to the beacon period partition information in the central beacon of neighbor networks.
303:CCO Multi net voting before common area broadcast networking coordinates instruction message;
For this step, CCO before the networking that common area is broadcasted Multi net voting coordinate instruction message for inform receive networking before Multi net voting coordinate instruction message this CCO of STA carry out Multi net voting coordination, and make STA stop ongoing networking behavior, to avoid STA, neighbor networks is carried out to CCO and coordinate to cause interference.
304:CCO sends central beacon;
For this step, the central beacon that CCO sends carries out networking for making the STA receiving this central beacon according to this central beacon.
In addition, CCO does not listen to the central beacon of neighbor networks in preset time period or CCO just sends central beacon after completing the network coordination, in addition, can also send central beacon under other circumstances, the present embodiment does not limit the actual conditions sending central beacon.
In addition, the present embodiment does not also send the concrete mode of central beacon to CCO and sends concrete scope and limit, and such as, CCO periodically sends central beacon to whole network scope.
Before 305:STA intercepts the networking of CCO broadcast in preset time period, Multi net voting coordinates instruction message, if Multi net voting coordinates instruction message listen to networking in preset time period before, then performs step 306, otherwise, perform step 307;
For this step, the preset time period that before STA carries out intercepting the networking of CCO broadcast, Multi net voting coordinates instruction message is greater than CCO intercepts time of the central beacon of neighbor networks, CCO broadcasts central beacon time and this STA receives and processes the summation of the time of central beacon, and the present embodiment does not intercept the networking of CCO broadcast to STA before, Multi net voting is coordinated to indicate the concrete numerical value of the preset time period of message to limit.
What deserves to be explained is, the present embodiment does not limit the concrete timing device that STA intercepts, and includes but not limited to, the timer in STA.The present embodiment does not also limit the concrete set-up mode of the preset time period intercepted.Such as, the time of the timer in STA is set, STA is intercepted within the time period of this set timer.
306:STA stopping cluster rows is, and after the central beacon receiving CCO transmission, carries out networking according to central beacon, performs step 308 afterwards;
During concrete enforcement, the present embodiment does not stop cluster rows for specifically limiting to STA, include but not limited to: if cluster is complete and for bunch head, then stop sending bunch beacon, and an instruction message is dismissed in broadcast bunch when STA Multi net voting before listening to networking coordinates instruction message; If cluster is complete and for bunch member, then stop sending finding beacon when STA Multi net voting before listening to networking coordinates instruction message; Non-cluster when if STA Multi net voting before listening to networking is coordinated to indicate message, then stop adding other bunch or setting up new bunch.After execution step 306, perform step 308.
In addition, because CCO sends after Multi net voting before networking coordinates instruction message in preset time period, central beacon can be sent, carry out networking to make the STA receiving this central beacon according to this central beacon.Therefore, after Multi net voting coordinates instruction message before STA listens to networking in preset time period, the central beacon that CCO sends can be intercepted in preset time period, and carry out networking operation according to the result listened to.
Wherein, before preset time period and STA that STA intercepts the central beacon that CCO sends intercept the networking that CCO broadcasts, Multi net voting coordinates to indicate the preset time period of message can be identical, also can be different, the present embodiment is not intercepted to STA the preset time period of central beacon that CCO sends and is limited, also not to STA intercept the preset time period of the central beacon that CCO sends and STA intercept the networking that CCO broadcasts before Multi net voting coordinate to indicate the relation of the preset time period of message to limit.
For intercepting the intercepted result of the central beacon that CCO sends and following four kinds of situations can be divided into according to the concrete mode of intercepted result execution networking operation in preset time period:
The first situation: intercepted result is the central beacon that STA listens to CCO transmission; For this kind of intercepted result, STA according to intercepted result perform networking operation time, STA receive CCO send central beacon, and to this CCO send association request message, with add this CCO be bunch head bunch, complete networking.
The second situation: intercepted result is the central beacon that STA does not listen to CCO and sends, but listens to bunch beacon that bunch hair send; For this kind of intercepted result, when STA performs networking operation according to intercepted result, STA receives bunch beacon, adds this bunch, complete networking according to a bunch beacon.If STA receives multiple bunches of beacons, then STA selects a bunch of beacon in bunch beacon received, and adds this bunch according to bunch beacon selected, and completes networking.The present embodiment does not limit the particular content of bunch beacon, and such as, a bunch beacon comprises resource scheduling information.Select the specific standards of a bunch of beacon to limit when the present embodiment does not receive multiple bunches of beacons to STA, include but not limited to, according to the resource scheduling information in bunch beacon, select a bunch of beacon.
The third situation: intercepted result is the central beacon that STA does not listen to CCO transmission, does not also listen to bunch beacon that bunch hair send.For this kind of intercepted result, STA according to intercepted result perform networking operation time, STA become bunch head and send bunch beacon, with make other STA receiving this bunch of beacon add with this STA be bunch head bunch, complete networking.
307:STA performs networking operation according to the situation of the beacon listened to;
For this step, the mode of the beacon that STA listens to and execution networking operation comprises following three kinds of situations:
The first situation: STA listens to the central beacon that CCO sends; For this kind of situation, when STA performs networking operation according to the beacon that listens to, STA receives the central beacon that CCO sends, and sends association request message to this CCO, with add this CCO be bunch head bunch, complete networking.
The second situation: STA does not listen to the central beacon that CCO sends, but listens to bunch beacon that bunch hair send; For this kind of situation, when STA performs networking operation according to the beacon listened to, STA receives bunch beacon, adds this bunch, complete networking according to a bunch beacon.If STA receives multiple bunches of beacons, then STA selects a bunch of beacon in bunch beacon received, and adds this bunch according to bunch beacon selected, and completes networking.
The third situation: STA does not listen to the central beacon that CCO sends, and does not listen to bunch beacon that bunch hair send yet.For this kind of situation, when STA performs networking operation according to the beacon listened to, before STA intercepts the networking of CCO broadcast again in preset time period, Multi net voting coordinates instruction message, is divided into again following four kinds of situations in this kind of situation:
If 1 listens to Multi net voting before networking in preset time period coordinate instruction message, then return and perform step 306.
If 2 listen in preset time period CCO send central beacon, then receive CCO send central beacon, and to this CCO send association request message, with add this CCO be bunch head bunch, complete networking.
If 3 listen to bunch beacon that bunch hair send in preset time period, then add this bunch according to a bunch beacon, complete networking; Wherein, if STA receives multiple bunches of beacons, then STA selects a bunch of beacon in bunch beacon received, and adds this bunch according to bunch beacon selected, and completes networking.
If 4 do not listen to any beacon in preset time period, this STA become bunch head and send bunch beacon, with make other STA receiving this bunch of beacon add with this STA be bunch head bunch, complete networking.
In addition, the present embodiment not to again intercept CCO broadcast networking before Multi net voting coordinate instruction message preset time period specifically determine that mode limits.Such as, STA is a time period of Stochastic choice in the longest time of intercept arranged, and again intercept the networking of CCO broadcast within this time period before, Multi net voting coordinates instruction message.Before STA intercepts the networking of CCO broadcast again Multi net voting coordinate the instruction preset time period of message and STA again intercept the preset time period of the central beacon that CCO sends and STA intercept the networking that CCO broadcasts before Multi net voting coordinate to indicate the preset time period of message can be identical, also can be different, the present embodiment does not intercept the networking of CCO broadcast again to STA before Multi net voting coordinate the instruction preset time period of message and STA again intercept the preset time period of the central beacon that CCO sends and STA intercept the networking that CCO broadcasts before Multi net voting coordinate to indicate the relation of the preset time period of message to limit.
308:CCO receives the association request message that STA sends, and STA is added this bunch.
For this step, CCO determines whether this STA belongs to other bunch after receiving the association request message of STA transmission, and gathering in association message of former bunch of head has comprised this STA.If this STA belongs to other bunch, and gathering in association message of former bunch of head has comprised this STA, then according to the association request message that receives, STA is added this bunch, and from topology information by STA from former bunch of deletion; Otherwise STA is directly added this bunch according to the association request message received by CCO.
In addition, whether the present embodiment does not belong to other bunch to STA, and the determination methods having comprised this STA in association message that gathers of former bunch of head limits, include but not limited to: due to bunch head can gather association message in record this bunch in each STA, if bunch head will gather association, message sends to CCO, the association message that gathers that then CCO send according to bunch hair determines whether STA belongs to other bunch, and gathering in association message of former bunch of head has comprised this STA.
In addition, the present embodiment does not limit the concrete implementation according to the association request message that receives STA being added this bunch.
The method that the present embodiment provides, by concentrator before the central beacon of transmission carries out networking, before broadcast networking, Multi net voting coordinates instruction message, the website making to receive this message stops cluster rows to be, carry out neighbor networks to avoid website to concentrator to coordinate to cause interference, improve power line communication network networking efficiency.
