For an above-mentioned difficult problem of the prior art, current most solution is all towards raising data transmission rate or increase transmission bandwidth.But, present inventor notices, a large amount of overlay informations is there is in the network of reality, if these overlapped data can be found in advance and carry out data processing in advance before transfer of data, make by network only transmission user disappearance part, then can not only reduce the wait time delay of user when transfer of data, the available bandwidth of network can also be saved.Meanwhile, due to mobile network-oriented, the network topological change that the mobility of user causes also should as the Consideration of data prediction.Around mobile subscriber, the user probably closed on has stored the information that this user needs, if now can find these information and realize the transmission of this information, then the server that user need not be connected to far-end goes to obtain these information, thus can reduce propagation delay time further.
For this reason, present inventor conceives in the following areas:
(1) discovery of overlay information and the flow process of Signalling exchange thereof how is realized;
(2) follow-up data transmission policies how is formulated after finding overlay information; And
(3) network topological information how is utilized to realize data prediction and transfer of data, to improve data transmission efficiency further.
Some embodiments of the present invention provide a kind of radio data transmission method and wireless data transmission device, can find that the overlapped data existed in network also carries out data processing in advance before data is transmitted, thus reduce the wait time delay of user when carrying out transfer of data, and save the available bandwidth of network.
Fig. 1 illustrates the indicative flowchart of radio data transmission method according to an embodiment of the invention.In this embodiment, local node wishes to obtain desired data from other nodes.In this radio data transmission method P100, in step s 110, local node sends data message and obtains request, to determine to the response that data message obtains request the destination node therefrom obtaining local node desired data according at least one other node.Wherein, data message obtains the data message that request comprises local node.The data message of local node comprises the information indicating following content: the theme of local node desired data and type, and the data with described theme and type stored in local node.
Here and below, exemplarily instead of restriction, the theme of data can be the theme of the content represented by data.Theme can be for a concrete event, such as, be that certain real-time grave news or certain class specifying information are as transport information.Theme also can be a fuzzy concept, such as when there is occurred events of public safety, user may not know to there occurs what concrete event, but can, with the fuzzyyer theme such as " public safety ", initiate to obtain request to the data message of similar content; After interdependent node receives this request, content-based search can be initiated, by the information feed back of all data relevant to theme to requesting node to the data that this locality stores.The type of data is such as voice, video, text etc.Correspondingly, the information of the type of designation data can be data format information, such as txt, JPEG, wmv, mp3 etc.
The information of the data stored in instruction local node can comprise the source-information of the data stored, such as network address, or source site information+this data content No. ID.Such as, the data content stored is one section of a film, and the film of longer duration can be multiple segment by the cutting of website, source, and every section is distributed an ID.
The type of the data stored in the type of local node desired data and local node can be a type or polytype, and the two does not have inevitable contact.
In the above-described embodiments, before carrying out transfer of data, carry out information interaction at the source node and destination node needing to carry out transfer of data with regard to data waiting for transmission.Send above-mentioned data message by local node (sometimes initiating node or data transfer request node also referred to as transfer of data below) to other nodes and obtain request, the data with described theme and type stored in the theme and type and local node comprising local node desired data in request are obtained at data message, the overlapped data making other nodes can find to exist with local node also carries out data processing in advance, thus enable local node determine suitable destination node according to the response of other nodes, and the nonoverlapping data of data stored with local node that may only obtain from destination node in local node desired data.The signaling consumption obtaining request and response thereof due to data message is little, but can avoid the transmission of overlapped data in subsequent data transmission, therefore effectively can save the network bandwidth.
Fig. 2 illustrates the further indicative flowchart of radio data transmission method according to an embodiment of the invention.As shown in Figure 2, in method P200, obtain except request except sending data message in step S210, in step S220, also receive at least one other node obtains request response to data message, and in step S230, from the response of at least one other node described, obtain data message and the node identification of one or more candidate target node, the data message of described candidate target node comprises and indicates the information of following content: what described candidate target node stored have described theme and type, and with the nonoverlapping data of data that stored in described local node, so that the data determined described destination node and will obtain from described destination node from candidate target node.It is part or all of that the data that candidate target node stores can have in the type of the data needed for local node.
Here, candidate target node can be send other nodes self comprising the response of the data message of described candidate target node, also can be the one or more nodes different from these other nodes.This will in following detailed description.
When candidate target node can be send comprise other nodes self of the response of the data message of described candidate target node time, response data message being obtained to request can not comprise node identification, because local node can obtain the node identification of these other nodes from the basic expense of the communications packet with these other nodes (such as from the packet header of communications packet comprising above-mentioned response).
Thus, local node can determine according to received response the destination node therefrom obtaining local node desired data.
Figure 3 illustrates the further indicative flowchart of radio data transmission method according to an embodiment of the invention.Wherein, in step S340, local node determines according to the data message in received response and node identification the destination node therefrom obtaining local node desired data.Such as, the data message that local node can be able to provide according to different candidate target nodes, selects one or more candidate target node therefrom to obtain the data needed for local node as destination node.If necessary, the data of needs can be split by local node, from different destination nodes, carry out data acquisition.Such as, when to have in the type of the data needed for local node respectively a part of for the data that multiple candidate target node stores, dissimilar data can be obtained respectively from multiple candidate target node.
After determining destination node, local node just can initiate data transfer request to destination node, the wherein concrete data message of instruction required for local node, then from the concrete data required for target node accepts, thus the data transmission procedure between local node and determined destination node is launched.
In one case, requesting node has stored a part for desired data content, need other parts downloading desired data content, and when destination node side has complete data content, destination node can before transmitting data to requesting node, the data stored according to requesting node to split this partial data content, and only transmit the part different from the data content that requesting node has stored to requesting node.
In another case, requesting node has stored a part for desired data content, need other parts downloading desired data content, and when destination node side has complete data content, requesting node can directly to the nonoverlapping part of part stored with requesting node in destination node request desired data content.
The transfer of data that any existing proper method carries out between node can be adopted, be not described in detail here.
The step S210-S230 shown in step S310-S330 and Fig. 2 in Fig. 3 is identical, no longer repeats here.
In the above embodiment of the present invention, achieve the discovery of overlay information and determine destination node simply according to overlay information.In order to select optimum destination node and/or determine to obtain which data content from destination node, to improve data transmission quality and QoS of customer further, in the examples below, also consider that the facility information of candidate target node determines the data transmission policies optimized, such as, determine destination node and/or transferring content.
In one embodiment of the invention, radio data transmission method also comprises the facility information obtaining candidate target node from the response of at least one other node.Described facility information comprises the information of at least one in the following content of instruction: the dump energy of the air interface type that candidate target node is supported to the information of the disturbed condition of its peripheral equipment, candidate target node and accordingly available bandwidth, candidate target node, the geographical position at candidate target node place and the data transmit-receive efficiency evaluation of candidate target node.
In another embodiment of the present invention, radio data transmission method also comprises the said equipment information obtaining described candidate target node from candidate target node.Such as, when candidate target node is not other nodes self of the response sending data message acquisition request, can asks by obtaining to candidate target node transmission data message, obtaining the facility information of candidate target node.
Along with the development of social networks, the public is consistent for focusing on of some focus incident to a great extent, therefore the demand for data is also consistent, relevant data may be stored in peripheral equipment, now can not data server download data distally, then corresponding information is obtained from peripheral equipment, the transmission bandwidth of peripheral equipment can be made full use of like this, also can realize data distribution simultaneously.Therefore, in a data transmission policies determination example, need to formulate different data transmission policies according to the position that data store.According to the geographical position at candidate target node place, can determine which week mid-side node stores the data needed for local node, and take nearby principle select target node.
Except nearby principle, alternatively or additionally can also adopt other selection strategy.Such as, local node can one or more according in the information such as the hardware condition of candidate target node (air interface supported, dump energy), network condition (available transmission bandwidth of each air interface and the disturbed condition to the channel of its peripheral equipment), determines destination node and/or adopt which kind of air interface to carry out transfer of data from candidate target node.The overall principle is such as that the candidate target node that prioritizing selection hardware condition is good, network condition is excellent carrys out the large data of transmitted data amount.
Such as, when needing to carry out in real time application process to the data of request, can according to the hardware condition of local node and destination node and network condition estimates the consumption of local node rated output and local node carries out the power consumption of transfer of data and the corresponding consumption of destination node.If the treatment effeciency of destination node is higher, then select to carry out data processing by parameter transmission mode at destination node.Otherwise, the computing of data is carried out at local node.
Except the selection to transmission node, transferring content also can be selected.In one embodiment of the invention, radio data transmission method also comprises: the data that the transmission priority of the data stored according to candidate target node is determined destination node and/or will be obtained from destination node.Such as, the candidate target node that local node can select the transmission priority of stored data high as destination node, and/or obtains the high data of transmission priority from such destination node.In this embodiment, the data message of candidate target node also comprises the information of instruction transmission priority.Or, the data message of candidate target node also can comprise the user interest grading of the data that instruction candidate target node stores and the information of user satisfaction grading, is determined the transmission priority of the data that candidate target node stores by local node according to the user interest grading in the data message of received candidate target node and user satisfaction grading.The data that total transmission priority determination principle is such as user interest grading high (showing the user's request amount of data large), satisfaction is high have high-transmission priority.
When determining the transmission priority of data, such as, collected user can be set up correlation to the grading of the interest of data and satisfaction grading and data, determining the transmission priority of each data according to the interest of user and satisfaction.
The data that can also determine destination node according to the combination of the transmission priority information of the data message of candidate target node, facility information and the data stored thereof and/or will obtain from destination node.
Such as, when destination node electricity abundance, the transmission of all desired datas is carried out to destination node.When destination node electricity is not enough but channel efficiency is higher, the data for high-transmission priority are transmitted.
Again such as, when destination node electricity is not enough and channel efficiency is common, this locality should be carried out for non-real-time service and store.If the memory space inadequate of local node, then delete the data of low transmission priority to provide memory space for the data of high-transmission priority.
By facility information and/or the transmission priority information such as hardware condition, network condition with other node switching candidate target nodes, can reduce the transmission of redundant information to greatest extent, auxiliary data transmission requesting node carries out the formulation of the transmission policy such as selection, the selection of transmission link, the selection of transmission priority of destination node simultaneously.
Describe local node obtains desired data scene from other nodes in the embodiment above.Under the scene of local node to other node uploading datas, similar with above-mentioned radio data transmission method, before carrying out transfer of data, judge whether there is overlapped data in network, and carry out transfer of data according to judged result.
Fig. 5 illustrates the indicative flowchart of radio data transmission method according to another embodiment of the invention.In this embodiment, local node is wished to other node uploading datas.In this radio data transmission method P500, in step S510, data upload checking request is sent at least one other node, described data upload checking request comprises the information indicating following content: local node will to the destination node of its uploading data, the data that local node will be uploaded, and the theme of data that will upload of local node and type.Then, in step S520, when know in destination node from the response of at least one other node described for data upload checking request stored the data with described theme and type, only to destination node upload in the data that local node will upload with the nonoverlapping part of data that stored in destination node.Certainly, this radio data transmission method P500 impliedly comprises local node and receives the step of at least one other node to the response of described data upload checking request, and local node obtains to the response of described data upload checking request the step with the information of the data of described theme and type stored in destination node from least one other node described.
In the above-described embodiments, before carrying out transfer of data, carry out information interaction at the source node and destination node that need to carry out transfer of data with regard to data waiting for transmission, thus local node can be made only to upload and the nonoverlapping data of data that stored in destination node to destination node.Because the signaling consumption of data upload checking request and response thereof is little, but the transmission of overlapped data in subsequent data transmission can be avoided, therefore effectively can save the network bandwidth.
Request or data upload checking request is obtained according to the data message that local node (as source node) sends, can form an interim network based on demand data, the node that this network comprises local node desired data by all or the node that needs receive uploading data from local node form.
In one embodiment of the invention, what local node and other nodes formed is distributed cyberrelationship.That is, local node can send data message to other nodes multiple and obtain request/data upload checking request, and receives corresponding response from the part or all of node described other nodes multiple.Such as, other nodes comprising the data of theme needed for local node and type can send to local node response data message being obtained to request, comprise data message and the node identification of a candidate target node i.e. these other nodes self in response.Again such as, the node of data needing or be ready to receive local node to upload in other nodes (as destination node) can send response for data upload checking request to local node, comprise in response stored in this node (as destination node) there are the theme of the data that local node will be uploaded and the data of type.
Under distributed network relation, enliven neighbor node in neighbor list and/or far-end server that local node such as can be preserved to local node by dedicated signaling or predetermined broadcast signaling send data message and obtain request.Correspondingly, local node also can enliven one or more neighbor node in neighbor list by dedicated signaling or predetermined broadcast signaling to this and/or far-end server sends data upload checking request.Enlivening what preserve in neighbor list is the neighbor node that local node can carry out with it good communication, can be set in advance in local node, and local node can preserve according to communications status periodic maintenance enliven neighbor list.
Fig. 4 illustrates the indicative flowchart safeguarded and enliven the method example of neighbor list.As shown in Figure 4, local node can regularly to sending or from receiving detectable signal (step S410) by the neighbor node in communication range by the neighbor node in communication range; And safeguard according to the quality of received neighbor node to the response of detectable signal or the detectable signal of neighbor node and enliven neighbor list (step S420).Such as, if receive the second best in quality detectable signal or detectable signal response that are not included in the neighbor node transmission enlivened in neighbor list, then this neighbor node is added and enliven neighbor list; On the other hand, if do not receive quality detection signal or the detectable signal response of certain neighbor node enlivened in neighbor list in scheduled time slot, or from the quality of the quality detection signal of this neighbor node or detectable signal response lower than predetermined quality requirement, then delete this neighbor node from enlivening neighbor list.
In another embodiment of the present invention, what local node and other nodes formed is centralized cyberrelationship.That is, local node can send data message and obtain request/data upload checking request to the specific node as central server in network, make response by this central server node to local node.Local node determines the destination node/transferring content of transfer of data according to the response of central server node.Such as, as response data message being obtained to request, central server node can comprise data message and the node identification of multiple node in the network of alternatively destination node in the response.As to data upload checking request response, central server node can comprise in the response stored in destination node there are the theme of the data that local node will be uploaded and the data of type.Above-mentioned candidate target node or destination node can be the one or more nodes different from this central server node, and also can comprise this central server node self.Central server node can be the server of functional independence, also can be other nodes any being integrated with above-mentioned functions in network.
