Embodiment two

Fig. 2 shows the flow diagram according to the network-building method of the embodiment of the present application two, the present embodiment still from center from The angle of equipment illustrates network-building method provided by the embodiments of the present application.As shown in Fig. 2, the network-building method can be used for group Build Radio Network System.

The network-building method is different according to the difference of the wireless communication protocol of use, below with BLE (Bluetooth Low Energy for) communicating, the overall process of the link establishment of entire Radio Network System is described.But those skilled in the art should be bright , BLE communication scenes are merely illustrative, and in actual use, those skilled in the art are referred to the application reality The scheme for applying example realizes the Radio Network System networking under other communication scenes.

The Radio Network System that network-building method through this embodiment is set up includes main equipment and from equipment, and main equipment can be with Carry out data transmission with from equipment, includes center from equipment and at least one periphery from equipment from equipment.Wherein, center is from equipment It is formed from equipment from equipment local area networks, and by outside from equipment local area networks for being connected and communicated with main equipment, and with periphery Enclose the link information that the first communication link is sent from equipment.Periphery can be built from equipment according to the link information of the first communication link It is vertical to intercept link, to intercept the data of the first communication link.

The network-building method of the present embodiment includes：

S201：Multiple and to preserve interactive information from carrying out information exchange between equipment, wherein interactive information includes identity letter Breath and key information.

In this step, it is multiple from equipment include center from equipment and one or more peripheries from equipment.

By taking Bluetooth communication as an example, before carrying out Radio Network System foundation by the equipment of Bluetooth communication, can first it carry out Information exchange, information exchange may be used the mode of device pairing and realize in Bluetooth communication.For example, by device pairing, it is more A interaction from the unpaired messages such as progress identity information, key information between equipment.Interactive pairing letter can be preserved from equipment Breath, for carrying out identification and data exchange in following link communication.

Can be triggered from device pairing behavior by certain specific behavior or event, for example, pressing external key, to from Equipment charge event etc..Wired either wireless transmission method may be used in pairing can be with measured communication protocol or private There is agreement completion.

By taking Bluetooth communication as an example, Bluetooth pairing is carried out from equipment by unpaired message.Wherein, unpaired message includes but unlimited In identity information and key information etc..Identity information includes：System address (System Address) and private address (Private Address), system address are in all addresses shared from the device, are from the external unification of equipment local area networks Address, and private address is then respectively from the exclusive address of equipment, for characterizing each from equipment.

From device pairing when the key information that interacts can be from being used on the second communication link in equipment local area networks Encryption information, to ensure the safety of information transmission.

It is said as first step it should be noted that, although in the present embodiment information exchange will be carried out from equipment It is bright, but those skilled in the art are not limited to it should be apparent that this step can be executed in the arbitrary opportunity before step S203 The present embodiment executes sequence.If in addition, having existed for corresponding interactive information from equipment, the step can be omitted.

S202：The first communication link is established with main equipment.

Main equipment is the owner of data source, and before Radio Network System sets up completion, main equipment is by constantly sweeping It retouches and intercepts, identification potentially can be initiated the connection actively from equipment after finding from equipment, create the first communication link.At this point, Main equipment is transferred to link connection state, while as the ends master of the first communication link, being responsible for link parameter maintenance and data Distribution.

It is the audient using data from equipment, is the consumer of data, before network foundation, as broadcaster (Advertiser), the relevant information of oneself is constantly broadcasted by system address (System Address), it would be desirable to be set by master Standby scanning is arrived, and establishes connection therewith.Wherein, it is established with main equipment centered on the slave equipment of the first communication link from equipment.

After from device power, button or detection in into working condition, three kinds of activities can be created：System broadcasts (system-ADV), directional broadcasting (Direct-ADV) and direct scan (Direct-Scan), wherein directional broadcasting and orientation are swept It is that the private address information matched based on apparatus described above is carried out to retouch, and system broadcasts are carried out based on system address.

As shown in figure 3, these three activities can be based on a kind of communication standard or two different logical using time division multiplexing Beacon standard carries out.Abscissa in Fig. 3 is time shaft, and as can be seen from Figure 3 in the same equipment, three kinds of differences are movable Time of origin is different, and carries out system broadcasts in the first time slot from equipment, broadcast, third are oriented in the second time slot Scanning is oriented in time slot.System broadcasts period (System Adv are formed between adjacent system broadcasts twice Interval), the directional broadcasting period (Direct Adv Interval) is formed between adjacent directional broadcasting twice, it is adjacent Twice direct scan section (Direct Scan Interval) is formed between direct scan.

Optionally, the detailed process that the first communication link is established at center from equipment with main equipment includes：

Center sends system broadcast message from equipment, so as to initiate the first connection after main equipment scanning to system broadcast message Request；Center receives the first connection request that main equipment is sent from equipment；The first communication chain is established in center from equipment and main equipment Road.

In other words, after main equipment scanning is listened to from the system broadcast message that device systems are broadcasted, can actively initiation connect It connects, i.e., connection request is generated according to the information of the slave equipment listened to, and be sent to the slave equipment listened to.This listen to from Equipment responds this connection request and establishes the first communication link with main equipment, realizes connection.During the slave equipment listened to is The heart is from equipment.

Simultaneously because respectively using identical system address (system address) from equipment carries out system broadcasts, once After the success of first communication link creation, other same system broadcasts using system address will be by master system mistake Therefore filter in entire Radio Network System, only can have first communication link.Slave equipment on first communication link Will become from the center of equipment local area networks from equipment, other from equipment be from the periphery in equipment local area networks from equipment.

S203：The second communication link is established from equipment at least one periphery, is formed from equipment local area networks.

Center carries out except through system address except system broadcasts from equipment and periphery from equipment, can also pass through demesne (Private Address) is oriented broadcast and direct scan for location, to establish each periphery from equipment and center from equipment it Between slave equipment local area networks.

Specifically, center carries out each periphery from equipment from equipment according to the unpaired message at least one periphery from equipment Direct scan receives the private address that each periphery is sent from equipment by directional broadcasting, wherein demesne of each periphery from equipment Location is different, and the second communication link is established in periphery corresponding with each private address from equipment respectively, is formed from equipment local area networks.

Wherein, it when trigger condition is set up, is successfully joined from the periphery of equipment local area networks and will switch through consultation from equipment As from the center of equipment local area networks (Device Lan) from equipment.

From equipment, there are two trigger conditions centered on equipment switching for periphery, meet one of them and can be carried out switching, First, establish the slave equipment of the first communication link with main equipment, if not from the former center of equipment local area networks from equipment, it can be with Negotiation is switched to new center from equipment, for example, after the completion of equipment local area networks foundation, main equipment scanning is arrived from equipment local area networks In one establish the first communication link from equipment from equipment, and with this, if should from equipment from equipment local area networks be not in The heart from equipment, then with current center centered on device protocol switching from equipment；Second, according to currently from equipment local area networks Center is switched over from the requirement of equipment.For example, when center judges that itself current electric quantity is too low from equipment, it can be according to screening Policy Filtering goes out suitable periphery from equipment, and negotiates carry out center from equipment and peripheral cutting from equipment from equipment with periphery It changes.

It should be noted that in the present embodiment for executing step S203 after first carrying out step S202, but actually answering In, step S202 is executed after step S203 can also be first carried out, alternatively, can also execute parallel.

S204：To it is each periphery from equipment send the first communication link link information so that it is each periphery from equipment according to chain Road information intercepts link with main equipment foundation, intercepts the defeated data of the first communication links.

From equipment and periphery after equipment establishes the second communication link, center can pass through the second communication from equipment at center Link sends the link information of the first communication link from equipment to the periphery, is intercepted (Listen) with providing to establish from equipment to the periphery The information of link.Wherein, the link information of the first communication link includes but not limited to temporal information, frequency information, the volume of link Code rule and encryption information.Optionally, link information can also include access address information.It is responsible for leading to first from equipment in center The link information of letter link is being distributed out of equipment local area networks, and periphery can establish synchronization from equipment according to these information (listen) link is intercepted, the data distributed on the first communication link are obtained.

Establish Radio Network System the first communication link, the second communication link and intercept link these three links it Afterwards, center can be to provide quality of data service (QoS from equipment for periphery from equipment：Quality of Service), with true Protect the data distribution reliability of the Radio Network System.

The quality of data service of the Radio Network System is described in detail below：

For the Radio Network System, distribute Various types of data, all purpose communication association to guarantee reliable and stable transmission View all can consider various handshake mechanisms in standard design, it is ensured that data can be sent to according to schedule.Wherein, referring herein to Handshake mechanism is for ensureing that the quality of data transmission provides reliable data service to carry out the smooth transmission of data.

It, can be safe and reliable and real-time under the premise of not changing main equipment in the network topology structure of the present embodiment The data by main equipment distribution entirely sent from equipment local area networks, need to ensure above-mentioned three kinds of links thus can By property.

And in the present embodiment, the communication protocol of standard, such as BLE (Bluetooth Low may be used in the first communication link Energy, low-power consumption bluetooth), BT (Bluetooth, classical Bluetooth technology standard), WI-FI, to carry out data transmission and data Quality services.

Second communication link is similar with the first communication link, also can be based on standard agreement, such as WI-FI communications, indigo plant Tooth communicates or IrDA is communicated etc..Communication protocol used by first communication link and the second communication link can it is identical can also It is different.

For the Radio Network System, the reliability of data distribution depends on intercepting the reliability of link.Due to outer It enclosing and obtains required data from equipment by silent mode of intercepting, main equipment can not perceive presence of these peripheries from equipment, because This can not also provide reliable quality of data service by standard agreement.So in the present embodiment, providing one kind passing through center The method for providing quality of data service from equipment from equipment for periphery, it is specific as follows：

As the signal strength (RSSI for intercepting link and receiving：Received signal strength indicator) it is higher than Periphery from the receiving sensitivity of equipment and it is noiseless under the conditions of, periphery can correctly parse data packet from equipment and obtain required number According to, it intercepts at this time normally, it is peripheral to obtain the data that main equipment is distributed by intercepting link from equipment.

When received signal strength is less than sensitivity condition or there is interference, periphery can not be by intercepting link from equipment Directly acquire data.In the present embodiment, when intercepting failure, by from the center of equipment local area networks (Device Lan) from equipment There is provided quality of data service (QoS service) from equipment for each periphery, i.e., ought intercept link deposit when abnormal, from periphery from equipment to Center proposes that data request service, center after receiving data request information, are incited somebody to action from equipment from equipment by the second communication link Relevant data are retransmitted to corresponding peripheral from equipment.

There are following three kinds of situations for actual data transmission procedure, is described as follows：

Fig. 4, which shows the first communication link and intercepts link, receives normal situation.When the first communication link and detect When listening link normal, center receives data from equipment by the first communication link, and periphery is received from equipment by intercepting link In the data that the first communication links are defeated.

In such cases, data transmission procedure is：As shown in figure 4, main equipment (Audio Source) connects week at one In phase (Connect Interval), a data packet (Packet_n) is sent to center from equipment by the first communication link, And a response message (ACK_n) returned from equipment (Audio Sink/Central) by center is received, which uses It is not lost normally in designation date packet.Later, main equipment continued within next connection period, was sent to center from equipment next A data packet (Packet_n+1), and receive the response message (ACK_n+1) returned from center from equipment.

For center is from equipment (Audio sink/central), connected in the period at one, it is logical by first Letter link receives a data packet (Packet_n) of main equipment transmission, and returns to a response message (ACK_ to main equipment N), which is used to indicate data packet and does not lose normally.Later, center is continued from equipment within next connection period, Next data packet (Packet_n+1) that main equipment is sent is received, and a response message (ACK_n+1) is returned to main equipment.

For periphery is from equipment (Audio sink/Peripherals), connected in the period at one, by intercepting Link receives a data packet (Packet_n) and a response message (ACK_n).Later, periphery is continued from equipment next In a connection section, next data packet (Packet_n+1) and a response message (ACK_n+1) are received.I.e. in the first communication The data of chain road transmitted in both directions, periphery can be listened to from equipment.

Fig. 5 shows situation of the center in the first communication link from device data reception failure.Fail in main equipment As scheduled receive center from ACK confirmation messages (response message) that equipment returns when, defined according to standard communication protocol, main equipment By the data before autonomous retransmission, until data transmission success or data failure are abandoned or link time-out disconnects, in the process It intercepts and is possible to will receive multiple identical data in (Listen) link, therefore before carrying out data processing, need to filter out The interception data repeated.

In such cases, data transmission procedure is：

As shown in figure 5, main equipment (Audio Source) was connected at one in the period (Connect Interval), pass through First communication link sends a data packet (Packet_n) to center from equipment, but fails to receive the sound that center is returned from equipment Message (ACK_n) is answered, that is, indicates the data-bag lost or there are other exceptions.At this point, in next connection period, main equipment is retransmitted The data packet (Packet_n Re-TX), if the response message of the data packet for the correspondence repeating transmission for receiving that center returns from equipment (ACK), then next data packet is normally sent in next connection period, otherwise continues to retransmit the data packet until data failure or chain Road time-out disconnects.

It for center is from equipment (Audio sink/central), is connected in the period at one, passes through the first communication Link fails to receive the data packet of main equipment transmission, thus not to main equipment returning response message, until next connection period Interior, center receives the data packet (Packet_n) that main equipment is retransmitted from equipment, and to main equipment returning response message (ACK).

For periphery is from equipment (Audio sink/Peripherals), connected in the period at one, by intercepting Link receives a data packet (Packet_n), and due to the first communication link exception, center is not listened to be returned from equipment Response message.The data packet (Packet_n Duplicate) and response message of repeating transmission are received within next connection period (ACK), periphery filters out the data packet of the repetition received from equipment.

Fig. 6 shows that after data interception failure, mistake is intercepted by being sent to center from device request from equipment for periphery The process of the data packet lost.

In such cases, data transmission procedure is：

As shown in fig. 6, for main equipment (Audio Source), period (Connect is connected at one Interval in), a data packet (Packet_n) is sent to center from equipment by the first communication link, and receive center The response message (ACK) returned from equipment.In next connection period, next data packet (Packet_n+1) is sent, and receive The response message that center is returned from equipment.

It for center is from equipment (Audio sink/Central), is connected in the period at one, passes through the first communication Link receives a data packet (Packet_n) of main equipment transmission, and returns to a response message (ACK) to main equipment.This Outside, there is exception due to intercepting link, periphery can not listen to data packet (Packet_n) from equipment, and center also passes through from equipment Second communication link receives the request data package from equipment (Audio sink/Perpherals) from periphery (ReqPacket_n), center responds the data packet that the request data package will be received by the first communication link from equipment (Packet_n) periphery is sent to from equipment, so that periphery is passed through the second communication link from equipment and is received the data packet (Packet_ n).In next connection period, center receives next data packet (Packet_n+1) from equipment, and returns and ring to main equipment Answer message.

It for periphery is from equipment, is connected in the period at one, fails to obtain what main equipment was sent by intercepting link Data packet (Packet_n), therefore request data package (ReqPacket_n) is sent to center from setting by the second communication link It is standby, obtain its data packet (Packet_n) for failing to receive by intercepting link from center from equipment.In next connection week Phase, periphery listen to next data packet (Packet_n+1) and response message (ACK) from equipment.

Therefore deposited when abnormal when intercepting link, center is received from equipment intercepts the abnormal periphery of link from equipment Data request information；Center is from equipment response data request message, to intercepting the abnormal periphery of link from equipment transmission data The requested data of request message, wherein data include the data sent by main equipment by the first communication link.To protect Data distribution reliability is demonstrate,proved.

In the present embodiment, it needs to provide quality of data service from equipment for periphery from equipment due to center, in order to ensure Data transmission credibility can carry out role and link switching from the center in equipment local area networks from equipment and periphery from equipment.

In the network topology structure of the present embodiment, there are Three roles：Main equipment, center are from equipment and periphery from setting It is standby.During the work time, can be according to respectively from the concrete condition of equipment, for example information about power, average data packet receive situation, into Row center is from equipment and periphery from the switching of equipment.While role switching, corresponding link switching also can same stepping Row.Common handoff procedure is as follows：

From equipment according to setting rule and the peripheral information from equipment, the center of progress switches from equipment at center.Specifically for example：

When meeting setting rule, center is switched to periphery from equipment from equipment, the first communication link carried thereon It can be switched to and intercept link.Wherein, setting rule can be the rule in the communication protocol used, can also be art technology The rule being different from communication protocol that personnel are arranged according to actual demand.

At the same time, a corresponding periphery from equipment can switch centered on from equipment, intercepting link and can also cut before It is changed to the first communication link.This handoff procedure is happened at synchronization point, and handoff procedure is transparent for main equipment, and master sets It is standby to be not necessarily to perceive this change procedure.

It should be noted that according to the difference of the communication protocol of use, the setting rules and methods switched over can not Together.

The network-building method can set up the Radio Network System distributed suitable for wireless data, realize multiple users share number According to meeting data distribution quality services demand.Role switching, link switching can be carried out from equipment according to the regular center of setting, Without being had an impact to main equipment.
