Embodiment
For making the object of the invention, technical scheme and advantage clearer, the present invention is done to specify further below in conjunction with accompanying drawing.
The present invention realizes that for making up system and implementation process SNS that short range SNS is professional are professional, at first needs a kind of wireless terminal based on Bluetooth technology, and it is simple in structure to require this network to have simultaneously, disposes rapidly the characteristics that cost of access is low.Bluetooth system just in time can satisfy this demand with the characteristic of the mode work of ad-hoc network (Ad hoc networks).
The provisional autonomous system of multi-hop that ad-hoc network is made up of one group of portable terminal that has a wireless transmitter.In this ad-hoc network, each portable terminal has both router feature, can constitute network topology arbitrarily through wireless connections.This ad-hoc network can work alone, and also can be connected with Internet or cellular radio.In any efficient communication scope, the status of all devices all is an equality.
For the wireless terminal based on Bluetooth technology, the equipment that at first proposes communicating requirement during networking is called main equipment (Master), and the passive equipment that communicates is called slave unit (Slave).Utilize TDMA (Time Division Multiple Access, time division multiple access) technology, main equipment can communicate with 7 slave units simultaneously at most and with a plurality of slave units (at most can above 200) maintenance synchronously but do not communicate by letter.The network that a main equipment and more than one slave unit constitute is called the piconet of bluetooth.
If exist the communication of equipment room between the plural piconet, then constituted the scatternet (Scatternet) of bluetooth.Based on the equality of TDMA principle and bluetooth equipment, arbitrary bluetooth equipment not only can be made main equipment but also can make slave unit in piconet and scatternet, also can the master and slave equipment of while double as.So the professional ad-hoc network of this realization SNS is typically not have central site network, has nature networking mode flexibly.
As shown in Figure 1, wireless terminal of the present invention is the wireless terminal that has bluetooth equipment, also comprises blueteeth network maintenance module and SNS application module.Wherein:
Bluetooth equipment is used for utilizing Bluetooth protocol to carry out radio communication with the wireless terminal with bluetooth equipment;
The blueteeth network maintenance module is based on the application module that Bluetooth protocol designs, and is used for being responsible for establishment, operation and the destruction of network;
The SNS application module is the social intercommunion platform that runs on the blueteeth network of having set up, is used to integration, the issue of the information of accomplishing, and user data is shared and function such as exchange.
Said blueteeth network maintenance module and SNS application module can be two software modules, all are built in the wireless terminal device.
Further, said blueteeth network maintenance module comprises again: the network construction module, and the network login module, master-slave equipment handing-over module, the network schemer handover module, wherein:
The network construction module is used for being responsible for the establishment of a blue teeth wireless territory net;
The network login module is used to land a blue teeth wireless territory net of having set up;
Master-slave equipment handing-over module when wireless terminal gets into or withdraws from the blueteeth network at place, is used to accomplish the handing-over of master-slave equipment identity;
The network schemer handover module is used between point-to-multipoint and point-to-point network schemer, switching.
Further, said SNS application module is including, but not limited to the application module of various SNS form of communication, and for example group is discussed, and intercom sends the bluetooth note, shared file, internet game etc.The SNS that the cell phone apparatus merchant can be custom made with self-character certainly uses.
The wireless terminal that has bluetooth equipment also can expand hardware module according to the SNS demands of applications, for example can the external connected electronic music keyboard, and game paddle etc.
Utilize the above-mentioned wireless terminal that has bluetooth equipment to set up the short range SNS system based on the blue teeth wireless terminal as shown in Figure 2, can set up by a wireless terminal as main equipment, other wireless terminal is as the piconet of slave unit.
Wireless terminal carries out bluetooth territory net when setting up as main equipment, needs to accomplish some netinits work.Initial procedure is wanted suitable configuration network setting, for example: maximum user number is set, the pattern that maybe can not come to light that is set to come to light, input suitable network name etc.If desired, any bluetooth PIN or link password can also be set.These initial work are accomplished by the network construction module of wireless terminal, can design these parameters of input or default settings on the interface.
Wireless terminal then can be set up piconet shown in Figure 2 as main equipment with this terminal based on above-mentioned initial parameter.After main equipment was set up piconet, other wireless terminal as slave unit can be linked into through network login module separately in this piconet, and logging in network uses bluetooth equipment ID to get final product, and has protected user's privacy.
In piconet shown in Figure 2, main equipment is responsible for providing clock sync signal and frequency hop sequences, and the address---bluetooth clock and bluetooth device address have defined the characteristic of piconet physical channel for other slave units of access network distribute.Wherein, the Bluetooth address of main equipment (BD_ADDR) decision frequency hop sequences and channel access code, the phase place and the time of the system clock decision frequency hop sequences of main equipment.
In each piconet, adopt one group of pseudo-random hop sequence to confirm 79 frequency hopping channels, this frequency hop sequences is unique for each piconet, by main equipment address and clock decision.The blue teeth wireless channel uses frequency hopping/time division multiplexing (FH/TDD) scheme; Channel is divided time slot with the 625ps time span; Clock according to piconet master is numbered time slot; Number is from 0 being a length of the cycle to (227-1) with 227, the corresponding frequency hopping frequency of each time slot, and frequency hopping rate was 1600 jumping/seconds usually.Main equipment only begins transmission information at the even number time slot, and slave unit only begins to transmit at the odd number time slot, and the beginning of packets of information is corresponding with the beginning of time slot.Utilize time division multiple access (TDMA), main equipment can communicate with 7 slave units simultaneously at most and with a plurality of slave units (at most can above 200) maintenance synchronously but do not communicate by letter.
Special, after two wireless terminal devices are shaken hands through blueteeth network, use when getting into some special SNS, like intercom, then can switch to point-to-point bluetooth communication mode through two wireless terminals network schemer handover module separately.Behind end of conversation, can switch back general mode equally.
Further, because the number of devices of a piconet carrying is limited, then need sets up a plurality of piconet when the equipment that inserts piconet above some and communicate.If exist the communication of equipment room between the plural piconet, then constituted the scatternet (Scatternet) of bluetooth, as shown in Figure 3.Main equipment in the Bluetooth protocol regulation, piconet also can be used as the slave unit in another piconet simultaneously.Blue teeth wireless terminal as 2 or 2 above piconet members has just become bridge (bridge) node.Bridge at most can only be as the main equipment of a piconet, but can be used as the slave unit of a plurality of piconets.Bridge is through each piconet of frequency hop sequence identification.When certain piconet sends data to another piconet, bridge switches to the relaying that corresponding network is accomplished data through the switching between the master-slave equipment (being to switch between the net of piconet) with its frequency.
Equity between each wireless terminal makes piconet be switching to possibility, adopts multiplexing technique to realize that piconet switches in the Bluetooth system.Having developed two kinds of base band data transmission modes in the Bluetooth protocol standard, is respectively synchronization link (SCO) and async link (ACL).If current system has only async link, a wireless terminal can get in current piconet and keep or park mode, and during this period, it can add other piconet through changing channel parameter; If synchronization links sets up, then can only the non-reserved time slot of between on, visit other piconet.
Because a plurality of piconets can not keep synchronously, so must adopt guard time to solve the out-of-alignment situation of a plurality of piconets.A wireless terminal as slave unit that adds two piconets must be taken into account two and join it self local clock compensation, and creates one or another main equipment clock.Because two master clocks are independent, can drift about by time of origin, synchronous in order to guarantee slave unit and two main equipments, must the periodic modification offset.The master-slave equipment switching was divided into for two steps: the time division duplex of (1) designated master device and slave unit (TDD) switches; (2) piconet of all piconet devices switches.When all slave units all receive frequency hopping synchronization (FHS) grouping, each equipment will use the new piconet parameter by new main equipment definition.So far, piconet switches completion.
The piconet of the system that the present invention is set up is used to realize that SNS is professional belongs to a kind of Ad hoc network.Ad hoc network is a kind of network that shows unique characteristics, and as a kind of novel wireless, multi-hop, no central distribution formula Control Network, it need not network infrastructure, the characteristics that have very strong self-organization, robustness, survivability and make up easily.In the Ad hoc network, each portable terminal has both router and two kinds of functions of main frame: as main frame, the terminal needs running face to application program of user; As router, corresponding Routing Protocol need be moved in the terminal, participates in packet forward and route maintenance work according to routing policy and routing table.Based on the equality of TDMA principle and bluetooth equipment, arbitrary bluetooth equipment not only can be made main equipment but also can make slave unit in piconet and scatternet, and each equipment all is potential main equipment.So it is typically not have central site network, has nature networking mode flexibly.
As shown in Figure 4, provided the flow chart of setting up the SNS operation system, wherein:
For a wireless terminal, at first detect whether there is available blueteeth network:
If do not exist, then this wireless terminal utilize the network construction module with this wireless terminal as main equipment, set up a micro bluetooth network network; After network is set up, utilize SNS application module operation SNS to use;
If there is existing available blueteeth network; Then can select whether to add existing micro bluetooth network network,, then can oneself create the micro bluetooth network network if do not add; If add; Then this wireless terminal signs in to existing micro bluetooth network network as slave unit network entry module, utilizes other users in SNS application module operation SNS application and the network to communicate after the adding.
Wherein, directly initiatively chain rupture in the time of need exitting network as the wireless terminal of slave unit.
Wherein, As the wireless terminal of main equipment when needs withdraw from the micro bluetooth network network; Then need join module and resource is discharged to other slave units be used for link setup, select a slave unit to carry out the function of main equipment and on baseband layer, rebulid communication through getting in touch each other participant through master-slave equipment.Become main equipment behind the slave unit link setup of reception resource, the parameter that provides according to preceding main equipment reorganizes the equipment in the network.When this mode has guaranteed that any role device exits network, can both guarantee that this network continues proper communication.Whole handoff procedure is accomplished by master-slave equipment handing-over module.
In micro bluetooth network, can set up point-to-point, point-to-multipoint connection through wireless channel between wantonly Unit two, can select to use which kind of pattern according to the needs of upper layer application scene.After for example getting into intercom SNS application, then can switch to point-to-point bluetooth communication mode through the network schemer handover module.Healthy and strong more speech quality and confidentiality can be guaranteed like this, behind end of conversation, general mode can be switched back.
Such scheme has solved the problem of each communication between devices of native system and master-slave equipment switching, is sightless to the user, and what attract the user is that the SNS that has the blueteeth network characteristic uses.
The realization of SNS application module of the present invention on wireless terminal is divided into more rudimentary APP mode and higher SNS+local model mode.Wherein, the APP mode is installed in SNS on the wireless terminal with the mode of independent APP, and the user need open application program could get into network environment of the present invention, is the mode of the information obtained of a kind of active.
SNS+local model mode is a kind of more senior mode, and is as shown in Figure 1, and it is incorporated into SNS with the local model of wireless terminal, accomplish that You are among us and we are among you.For example the Home of mobile phone terminal, Contacts, Camera, Album, module such as Music Player and SNS combine, and upgrade the state of these local model and carry out resource-sharing through blueteeth network at any time.For example, from blueteeth network receive the bluetooth note will be from the Home interface eject notification; Can Contacts be sent to the user in the network through bluetooth; Other users in the network can take pictures through the Camera that bluetooth is handled other users; Music Player can make a plurality of users music appreciating or the like together synchronously through blueteeth network.Before the mode of SNS+local model initiatively is pushed to user plane with information, be the SNS wireless terminal of real meaning.
These SNS application modules are including, but not limited to the application module of various SNS form of communication.Discuss like group, intercom sends the bluetooth note, shared file, recreation etc.The application appearance of various novelties can constantly be arranged along with the maturation of blueteeth network.The SNS that the cell phone apparatus merchant can be custom made with self-character certainly uses, and also can run with the mode of App Store.
