A kind of method, system and device of chatting realized
Technical field
The present invention relates to the application technology in the ZigBee network, particularly a kind of method, system and device of in the ZigBee network, realizing chat.
Background technology
ZigBee is a kind of emerging short distance, the radio network technique of low rate, is mainly used near radio and connects.ZigBee has the consensus standard of oneself, coordinates to realize communication between tens thousand of small nodes mutually.These nodes only need energy seldom, by radio wave data are passed to another node from a node in the mode of relay.The ZigBee network can be made up of 64k node, and internodal representative communication distance is 75 meters, but internodal communication distance also can extend to hundreds of rice.
The basis of ZigBee is IEEE (IEEE, Institution of Electricaland Electronics Engineers) 802.15.4.Because IEEE has only related to medium access control (MAC, Medium Access Control) layer and physical layer protocol, so ZigBee alliance expanded IEEE, and its network layer protocol, safe floor and application layer have been carried out standardization.
For the ZigBee network, the layer structure of its network from the bottom to the high level, comprises based on the physical layer of IEEE 802.15.4 and network layer, safe floor and the application programming interfaces of MAC layer and the definition of ZigBee alliance as shown in Figure 1 successively.Wherein, network layer mainly realize in the ZigBee network node adding or deviated from network, receive or abandon other nodes, route querying and transmit functions such as data, support multiple topological structures such as star, tree-like and grid; Safe floor is mainly realized functions such as key management and access; Application programming interfaces are used for providing to the father of node interface of application program, comprise and use the interface that (APS), ZigBee device object (ZDO) and application specifications (Application Profile) are supported in the sublayer, realize the management of upper strata to node, defined some device descriptions in the application specifications, and order of transmitting between these equipment and attribute (message).
Corresponding different application has different application project groups in the ZigBee network, such as local automation (HA, Home Automation), local control lamp (Home Controls Ligting) and telecommunications application (TA, Telecom Applications PTG) etc.In the ZigBee network, the order of some in the application project group and message have been formed one bunch (Cluster), if the different nodes in the network are supported identical bunch, the order and the message that define in then just can utilizing between these nodes bunch communicate.For example, telecommunications is used working group and is just paid close attention to the application of ZigBee network on telecommunications, has defined at present to pay by mails bunch, is used for paying by mails.
But, at present telecommunications use also be not used in the working group chat bunch, also just can't in the ZigBee network, chat.
In fact chat is exactly the process of transmission instant message between the heterogeneous networks entity, for example adopts Open Mobile Alliance (OMA, Open Mobile Alliance)-instant message (IM, Instant Messaging) technology to chat.Below to OMA-IM how to realize the chat simply introduce.
OMA-IM sets up on IP multimedia subsystem, IMS (IMS) framework, and it utilizes initial session protocol (SIP, Session Internet Protocoal) as host-host protocol.Because OMA-IM is on the IMS framework, therefore can compatible various Access Networks.OMA-IM provides three types message, is respectively: Pager-mode, utilize the payload segment in the sip message to send SMS message; Large-mode uses when message-length surpasses 1300 bytes, and under this pattern, session will finish immediately in case the message transmission is finished; Session-mode is used for setting up a session between network entity, to transmit instant message, set up between the network entity of session and can transmit public message, also can send classified information between the network entity that limits simultaneously.
But, the chat of OMA-IM standard application between the network entity that is in large-scale diverse geographic location, and the ZigBee network only is applied to the communication between the interior among a small circle node.Because applied environment difference is so can't be applied in OMA IM in the ZigBee network.For example, with in the scope of market as in the ZigBee network, adopt the OMA-IM standard just can't be to find other users of the similar use node of interest to do shopping jointly by chat in inside, market, this is because the OMA-IM standard is towards large-scale (as the whole world), can not be among a small circle, as realizing chat among a small circle in the scope of market.
Therefore, the applicant finds can't realize chat between the node in the ZigBee network at present.
