Fig. 1 is the Organization Chart of data transferring system 100 of the present invention.Data transferring system 100 comprises running gear UE1, the first networking NW1, the second networking NW2, Content Provider (Content Provider) CTP and resource management apparatus RM.Running gear UE1 is linked to the first networking NW1 by the first path L1, running gear UE1 can be that wireless connections are in the base station of the first networking NW1 herein, running gear UE1 is linked to the second networking NW2 by the second path L2, and running gear UE1 can be that wireless connections are in the base station of the second networking NW2 herein.Running gear UE1 inside has route planning management formula (Routing Policy Manager) RPM, and it has executory formula inventory S, and has many executory application AP1, AP2 to APN in formula inventory S.Resource management apparatus RM and Content Provider CTP is linked to the first networking NW1 and the second networking NW2.First networking NW1 and the second networking NW2 is heterogeneous networking (Heterogeneous Network) each other.But, although only consider the first networking NW1 and the second networking NW2 in the present embodiment, but the present invention is not limited thereto, other embodiment can also consider K heterogeneous networking, and resource management apparatus RM and/or Content Provider CTP is also not limited to outside to be connected on the first networking NW1 and the second networking NW2, such as in other is implemented, in resource management apparatus RM can be, be built in the circuit in running gear UE1.In running gear UE1, executory application AP1, AP2 to APN have respective frequency range use amount respectively, first running gear UE1 can be obtained respectively and be linked to the line quality LQ1 of the first networking NW1 by the first path L1 and be linked to the line quality LQ2 of the second networking NW2 by the second path L2, and after detecting the bandwidth requirements of these executory application AP1, AP2 to APN, produce a frequency range allocation result.Next, running gear UE1 according to frequency range allocation result, can carry out data line to the first networking and/or the second networking, and performs the networking transmission of each application AP1, AP2 to APN.Therefore, the frequency range that all executory applications use will be dispensed in the frequency range that two heterogeneous networkings (NW1 and NW2) provide with optimized, and reaches the object of promoting transmission rate.Detailed frequency range distribution method will be described in down.
Fig. 2 is the schematic diagram of the frequency range distribution method of Fig. 1 embodiment.As shown in Figure 2, consider N number of just at executory application AP1, AP2 to APN in running gear UE1, each application has its bandwidth requirements.In the present embodiment, the bandwidth requirements of each executory application is divided into two classes.The first kind is minimum bandwidth requirements (Minimum Bandwidth Requirement).Equations of The Second Kind is the highest bandwidth requirements (Maximum Bandwidth Requirement), is also called optimization frequency range (Optimal Bandwidth).In fig. 2, the minimum bandwidth requirements of application AP1, AP2 to APN is respectively C1, C2 to CN.The highest bandwidth requirements of application AP1, AP2 to APN is respectively V1, V2 to VN.In the present embodiment, minimum bandwidth requirements C1, C2 to CN can be the state updating of application, navigation system and/or the frequency range periodically needed for return, also can be the lower frequency range amount that the user when application is prospect formula is used.And the highest bandwidth requirements V1, V2 to VN can be the application frequency range used when full speed transfer data, or frequency range amount required when user uses the multimedia application formula of high-res.Route planning management formula RPM can obtain out all executory application AP1, the minimum bandwidth requirements summation C of AP2 to APN and the highest bandwidth requirements summation V in action in device UE1, and wherein C is defined as the totalling of minimum bandwidth requirements C1, C2 to CN, namely
v is defined as the totalling of the highest bandwidth requirements V1, V2 to VN, namely
n is positive integer.Route planning management formula RPM also can obtain out the upper line quality linking corresponding networking of networking interface NWD1 to NWDM all on running gear UE1.According to Fig. 1, if only consider the situation of the first networking NW1 and the second networking NW2, route planning management formula RPM will obtain out running gear UE1 is linked to the first networking NW1 line quality LQ1 by path L1, and obtains out running gear UE1 is linked to the second networking NW2 line quality LQ2 by path L2.But the present invention also can consider the situation at K heterogeneous networking, as shown in Figure 2, if consider K heterogeneous networking, route planning management formula RPM will obtain out the line quality LQ1 to LQK at K networking, and wherein N and K is positive integer.In order to express conveniently, at this only with the example explanation of the first networking NW1 and the second networking NW2.In the present embodiment, the line quality LQ1 of the first networking NW1 and the line quality LQ2 of the second networking NW2 can be the networking metric parameter of any definition, such as transmission speed (Transmission Rate), transmission delay (Transmission Delay), packet error (Packet Error Rate), power loss characteristic (Power Consumption) or expense (Cost).And the frequency range allocative decision that produces of route planning management formula RPM, its target function will the unit of corresponding above-mentioned networking measure.Such as user is for all executory its transmission delays of application AP1 to APN of optimization, then the line quality LQ2 of the line quality LQ1 of the first networking NW1 and the second networking NW2 will be set as the situation (can be Content Provider CTP to detect) considering transmission delay by route planning management formula RPM.If user is for the transmission speed of all executory application AP1 to APN of optimization, then the line quality LQ2 of the line quality LQ1 of the first networking NW1 and the second networking NW2 will be set as the situation considering transmission speed by route planning management formula RPM.Below how explanation running gear UE1 will be distributed in all executory application AP1 to APN frequency range to the first networking NW1 used and the second networking NW2.
Here the method in all executory application AP1 to APN of running gear UE1 distribution frequency range to the first networking NW1 used and the second networking NW2 is described in detail with an example.First the state of running gear UE1 is set, the current executory application of running gear UE1 comprises AP1 to APN, wherein AP1 is prospect application (Foreground Program), and AP2 to APN is background applications formula (Background Program).Therefore, route planning management formula RPM can obtain out minimum bandwidth requirements summation C, and C is the prospect Minimum requirements frequency range C1 of prospect application AP1 and background Minimum requirements frequency range C2 to the CN sum of background applications formula AP2 to APN
route planning management formula RPM also can obtain out the highest bandwidth requirements summation V, and V is the prospect the highest demand frequency range V1 of prospect application AP1 and background the highest demand frequency range V2 to the VN sum of background applications formula AP2 to APN
and the definition of prospect application AP1 can be the formula that user performs at present on screen, there is higher relative importance value (Priority), and the definition of background applications formula AP2 to APN can be formula or resident formula (Resident Program) that running gear UE1 is hidden in background in multiplex system.In the present embodiment, the highest bandwidth requirements summation V can be greater than minimum bandwidth requirements summation C, and in prospect application AP1, prospect the highest demand frequency range V1 also can be greater than prospect Minimum requirements frequency range C1.For example, when prospect application AP1 demand frequency range V1 line the highest for prospect of the application, data transmission may be carried out for user for using the media of high-res.Otherwise, when prospect application AP1 is for prospect of the application Minimum requirements frequency range C1 line, data transmission may be carried out for user for using the media of low-res.Route planning management formula RPM also can obtain out the line quality LQ1 of the first networking NW1 and the line quality LQ2 of the second networking NW2.Route planning management formula RPM will according to the line quality LQ1 of the first networking NW1, the line quality LQ2 of the second networking NW2, the highest bandwidth requirements summation V and minimum bandwidth requirements summation C, produce a frequency range allocation result, and utilize this frequency range allocation result to carry out data line to the first networking NW1 and/or the second networking NW2, and perform the data networking transmission of application AP1 to APN.For example, if the line quality LQ1 of the first networking NW1 is better than the line quality LQ2 of the second networking NW2, the frequency range of the first networking NW1 is distributed to prospect application AP1 by route planning management formula RPM, and makes background applications formula AP2 to APN optionally use the frequency range of the first networking NW1 and the second networking NW2.That is, in total frequency range NWB2 that the total frequency range NWB1 provided at the first networking NW1 and the second networking NW2 provides is little unlike the highest bandwidth requirements summation V, the frequency range of prospect application AP1 can be dispensed to compared with good line quality that (transmission speed is large, transmission delay is little, error rate is low ... etc.) the first networking NW1, with allow user before use scape application AP1 time can network swimmingly, and background applications formula AP2 to APN is optionally used the frequency range of the first networking NW1 (if the first networking still has frequency range space) and the second networking NW2, certain level is still had to make the line quality of background applications formula AP2 to APN formula.But, the mode that the present invention distributes frequency range is not limited to aforesaid way, also can be other combination, for example, if when the line quality LQ1 of the first networking NW1 is much better than the line quality LQ2 of the second networking NW2, prospect application AP1 and background applications formula AP2 to APN can be set as the frequency range using the first networking NW1 completely by route planning management formula RPM.According to the above-mentioned characteristic (according to Minimum requirements frequency range summation C and the highest demand frequency range summation V) application AP1 and APN being used frequency range, use bandwidth requirements is dynamically dispensed to (the first networking NW1 and the second networking NW2) in different heterogeneous networkings.This method simultaneously using the frequency range at multiple heterogeneous networking, except can increasing channel capacity (Chanel Capacity), can also make transmission rate information obtain and promote.
In the present embodiment, obtaining prospect application AP1 and background applications formula AP2 to APN uses frequency range to obtain for real-time operation or in predetermined period of time.That is, when user optionally to close in execution application with when opening application in non-executing, the use frequency range of new prospect application AP1 ' and new background applications formula AP2 ' to APN ' can be routed planning management formula RPM and detected, and therefore minimum bandwidth requirements summation C and the highest bandwidth requirements summation V will be updated.Similar above-mentioned frequency range allocation flow, route planning management formula RPM will according to the highest bandwidth requirements summation V ' after the line quality LQ2 of the line quality LQ1 of the first networking NW1, the second networking NW2, renewal and the minimum bandwidth requirements summation C ' after upgrading, produce a new frequency range allocation result, and the frequency range allocation result utilizing this new carries out data line to the first networking NW1 and/or the second networking NW2, and perform the data networking transmission of application AP1 ' to APN '.Therefore, when the executory application frequency range of running gear UE1 changes, route planning management formula RPM can its variable quantity of detecting of instantaneity (Real-Time), and redistributes and use frequency range to the first networking NW1 and the second networking NW2.In addition, as shown in Figure 1, running gear UE1 can also carry out frequency range distribution by the resource management apparatus RM being linked to the first networking NW1 and the second networking NW2, the mode of distributing is similar to aforesaid frequency range distribution method, difference is that running gear UE1 can return the situation (comprising minimum bandwidth requirements summation C and the highest bandwidth requirements summation V) of the use frequency range of current executory application to resource management apparatus RM, and resource management apparatus RM can according to the minimum bandwidth requirements summation C of running gear UE1 return and the highest bandwidth requirements summation V, and first networking NW1 line quality LQ1 and the line quality LQ2 of the second networking NW2, frequency range distribution is carried out to applications all in running gear UE1.And this mechanism utilizing multiple heterogeneous network transmission, separately can be applicable to the delivery acceleration of the audio-visual transport tapes such as multimedia in the present invention.For example, if prospect application AP1 is the formula of multimedia video transport tape (Media/Video Data Stream), such as YouTube.Then audio-visual data transmission can be cut into the discrete audiovisual materials of several time interval by running gear UE1, and such as interval is the audiovisual materials of 0 ~ 1 minute the very first time, and the second time interval is audiovisual materials of 1 ~ 2 point etc.Application AP1 is done frequency range and distributes by running gear UE1, utilizes the first networking NW1 to transmit the audiovisual materials in this very first time interval simultaneously, and utilizes the second networking NW2 to transmit the audiovisual materials of this second time interval.Because data frequency range can be scattered in the first networking NW1 and the second networking NW2 by the present embodiment, and use the frequency range at two networkings to carry out data access and transmission simultaneously, therefore solve originally because of frequency range restriction, singly cannot be carried out the problem of audiovisual materials transmission by the first networking NW1 and the second networking NW2.In addition, if the line quality of the first networking NW1 and the second networking NW2 is close, then the transmission time of application AP1 will be reduced to originally about 1/2.Because data transmission is two heterogeneous networkings by time division multiplexing, therefore for single networking, add more free time, effectively can lower network transmission and to be jammed the probability of (Traffic Congestion).
The method of the frequency range distribution that the present invention is directed to multiple running gear will be described below.Fig. 3 describes the Organization Chart of data transferring system 200 of the present invention.Data transferring system 200 of the present invention is the situation considering X (X is positive integer) individual running gear and two heterogeneous networkings.In figure 3, data transferring system 200 comprises first act device UE1 to X running gear UEX, the first networking NW1, the second networking NW2, Content Provider (Content Provider) CTP and resource management apparatus RM.Except X running gear UEX, other (X-1) individual running gear UE1 to UEX-1 is the running gear originally within the scope of the first networking NW1 and the second networking NW2 networking, and X running gear UEX is outside running gear (External Mobile Device), and for line in the first networking NW1 and the second networking NW2.For convenience, below by first within the scope of networking to X-1 running gear UE1 to UEX-1 referred to as running gear UE1 to UEX-1, by X running gear UEX of outside referred to as outside running gear UEX.Running gear UE1 is linked to the first networking NW1 by path L11, is linked to the second networking NW2 by path L12, and running gear UE2 is linked to the first networking NW1 by path L21, is linked to the second networking NW2 by path L22.The rest may be inferred, and the running gear UEX-1 of UEX-1 is also linked to the first networking NW1 and the second networking NW2 respectively by two paths.And outside running gear UEX is linked to the first networking NW1 by path LX1, be linked to the second networking NW2 by path LX2.In the present embodiment, running gear UE1 to UEX inside has route planning management formula (Routing Policy Manager) RPM1 to RPMX respectively, and has executory formula inventory S1 to SX respectively.For example, have many executory application AP11, AP12 to AP1N1 corresponding in the executory formula inventory S1 of running gear UE1, wherein N1 is positive integer.Have many executory application AP21, AP22 to AP2N2 corresponding in the executory formula inventory S2 of running gear UE2, wherein N2 is positive integer.The rest may be inferred, and have many executory application APX1, APX2 to APXNX corresponding in the executory formula inventory SX of outside running gear UEX, wherein NX is positive integer.Running gear UE1 to UEX inside has route planning management formula RPM1 to RPMX respectively.Its effect has been described in Fig. 2, does not repeat them here.Resource management apparatus RM and Content Provider CTP is linked to the first networking NW1 and the second networking NW2.First networking NW1 and the second networking NW2 heterogeneous networking each other.But, although only consider the first networking NW1 and the second networking NW2 in the present embodiment, but the present invention is not limited thereto, other embodiment can also consider K heterogeneous networking, and resource management apparatus RM and/or Content Provider CTP is also not limited to outside is connected on the first networking NW1 and the second networking NW2.In other is implemented, in resource management apparatus RM can be, be built in the circuit in running gear.In each running gear UE1 to UEX, executory application all has respective frequency range use amount.And the route planning management formula RPM1 to RPMX in each running gear UE1 to UEX can obtain out the bandwidth requirements of application in execution.For example, the route planning management formula RPM1 in running gear UE1 can obtain out all executory application AP11, the minimum bandwidth requirements summation C (1) of AP12 to AP1N1 and the highest bandwidth requirements summation V (1).As the definition described in Fig. 1, minimum bandwidth requirements summation C (1) is all application AP11, the minimum bandwidth requirements C11 of AP12 to AP1N1, the totalling of C12 to C1N1, namely
and the highest bandwidth requirements V11 of the highest bandwidth requirements summation V (1) for all application AP11, AP12 to AP1N1, the totalling of V12 to V1N1, namely
in like manner, route planning management formula RPM2 in running gear UE2 can obtain out all executory application AP21, the minimum bandwidth requirements summation C (2) of AP22 to AP2N2 and the highest bandwidth requirements summation V (2), wherein minimum bandwidth requirements summation C (2) is defined as all application AP21, the minimum bandwidth requirements C21 of AP22 to AP2N2, the totalling of C22 to C2N2, namely
and the highest bandwidth requirements summation V (2) is defined as all application AP21, the highest bandwidth requirements V21 of AP22 to AP2N2, the totalling of V22 to V2N2, namely
and the route planning management formula RPMX in outside running gear UEX can obtain out all executory application APX1, the minimum bandwidth requirements summation C (X) of APX2 to APXNX and the highest bandwidth requirements summation V (X), wherein minimum bandwidth requirements summation C (X) is defined as all application APX1, the minimum bandwidth requirements CX1 of APX2 to APXNX, the totalling of CX2 to CXNX, namely
and the highest bandwidth requirements summation V (X) is defined as all application APX1, the highest bandwidth requirements VX1 of APX2 to APXNX, the totalling of VX2 to VXNX, namely
in the present embodiment, the bandwidth requirements summation gone out acquired by each running gear can be broadcasted (such as can utilize specific application that bandwidth requirements index is shared with all running gears), therefore when outside running gear UEX is for carrying out data line to the first networking NW1 and the second networking NW2 (that is when sending the request of data line), all running gear UE1 to UEX will coordinate, distribute with the frequency range of the outside running gear UEX making original running gear UE1 to UEX-1 within the scope of networking and external request data line and be balance and optimized.And how all running gear UE1 to UEX will coordinate the step of frequency range distribution, and the frequency range of the running gear UEX how processing external request line distributes, and will be specified in down.
Here describe the mode of data transferring system 200 frequency range distribution with an example, particularly describe data transferring system 200 at different conditions, to the frequency range processing method of running gear UE1 to UEX.In order to simplified characterization, several representational frequency range condition below will be considered:
(A) if when outside running gear UEX is for carrying out data line to the first networking NW1 and the second networking NW2, and the bandwidth requirements that data transferring system 200 detects UE1 to UEX meets
the wherein NWB1 maximum frequency range amount of supporting for the first networking NW1.Even if this situation represents that all running gear UE1 to UEX use the speed line of minimum bandwidth requirements, the first networking NW1 still cannot allow the running gear UEX supported for line add (meeting excessive loads).Therefore, data transferring system 200 will forbid that the application of outside running gear UEX uses the first networking NW1 to transmit data.In like manner, if meet
the wherein NWB2 maximum frequency range amount of supporting for the second networking NW2, data transferring system 200 will forbid that the application of outside running gear UEX uses the second networking NW2 to transmit data.
(B) if when outside running gear UEX is for carrying out data line to the first networking NW1 and the second networking NW2, and the bandwidth requirements that data transferring system 200 detects UE1 to UEX meets
and
the wherein NWB1 maximum frequency range amount of supporting for the first networking NW1.This situation represents that the first networking NW1 can the frequency range of all executory applications when using minimum bandwidth requirements in load running gear UE1 to UEX, but under the condition that the running gear UE1 to UEX-1 within the scope of networking cannot be made all to use the highest bandwidth requirements at all executory applications, allow outside running gear UEX for line to add under the state of the highest frequency range use amount.Therefore, data transferring system 200 will limit the frequency range that outside running gear UEX uses the first networking NW1.In like manner, if meet
and
the wherein NWB2 maximum frequency range amount of supporting for the second networking NW2, data transferring system 200 will limit the frequency range that outside running gear UEX uses the second networking NW2.
(C) if when outside running gear UEX is for carrying out data line to the first networking NW1 and the second networking NW2, and the bandwidth requirements that data transferring system 200 detects UE1 to UEX meets
the wherein NWB1 maximum frequency range amount of supporting for the first networking NW1.In this case, due to
can be greater than
therefore
the condition set up must meet
the condition set up, represent that the first networking NW1 not only can frequency range when all executory applications all use minimum bandwidth requirements in load running gear UE1 to UEX, also can frequency range when all executory applications all use the highest bandwidth requirements in load running gear UE1 to UEX.Therefore, data transferring system 200 can not limit the frequency range that outside running gear UEX uses the first networking NW1.That is the running gear UE1 to UEX-1 within the scope of all networkings and outside running gear UEX all can use respective optimized frequency range allocation result line.In like manner, if meet
the wherein NWB2 maximum frequency range amount of supporting for the second networking NW2.Data transferring system 200 can not limit the frequency range that outside running gear UEX uses the second networking NW2.
(D) if when outside running gear UEX is for carrying out data line to the first networking NW1 and the second networking NW2, and the bandwidth requirements that data transferring system 200 detects running gear UE1 to UEX meets
the wherein NWB1 maximum frequency range amount of supporting for the first networking NW1.Even if this situation represents that all running gear UE1 to UEX use the speed line of minimum bandwidth requirements, the first networking NW1 still cannot allow the running gear UEX supported for line add (meeting excessive loads).Now, data transferring system 200 will adjust in the running gear UE1 to UEX-1 within the scope of networking, the minimum bandwidth requirements summation of application in all uses at least one running gear.In other words, data transferring system 200 will reduce
bandwidth requirements amount, the application carrying out satisfied outside running gear UEX still can carry out data transmission to the first networking NW1, that is adjustment after
add the maximum frequency range amount NWB1 that C (X) can be less than the first networking NW1 and supports.In like manner, if meet
the maximum frequency range amount that NWB2 supports for the second networking NW2, data transferring system 200 will adjust in the running gear UE1 to UEX-1 within the scope of networking, and at least one running gear, the minimum bandwidth requirements summation of application in all uses, namely reduces
bandwidth requirements amount, the application that carrys out satisfied outside running gear UEX still can carry out data transmission (after adjustment to the second networking NW2
add the maximum frequency range amount NWB2 that C (X) can be less than the second networking NW2 and supports).
The record of the minimum bandwidth requirements summation of the running gear UE1 to UEX-1 within the scope of this adjustment networking and state, will be stored in respective running gear, or be registered in resource management apparatus RM.The frequency range that the state recording of these frequency ranges adjustment comprises running gear UE1 to UEX-1 reduces the information such as (interest concessions) ratio and bandwidth requirements ratio.Therefore, if when outside running gear UEX is again for carrying out data line to the first networking NW1 and the second networking NW2 backward, can the state recording of the respective frequency range adjustment according to the running gear UE1 to UEX-1 within the scope of networking, or according to the state recording that the frequency range that resource management apparatus RM stores adjusts, running gear UE1 to UEX-1 within the scope of networking gets final product active accommodation minimum bandwidth requirements summation separately, or coordinate via resource management apparatus RM, make outside running gear UEX still can carry out data transmission with minimum bandwidth requirements summation C (X).And the wish in order to encourage UE1 to UEX-1 to carry out frequency range reduction (interest concessions), the numerical value that can change into a kind of systematic contributions degree of the interest concessions behaviors such as these ratios and frequency range adjustment, when carrying out data line to the first networking NW1 or the second networking NW2 again after UE1 to UEX-1 leaves, data transferring system 200 just offsets according to the numerical value of the systematic contributions degree of these devices, allows these devices allocate priority that is better or minimum frequency range.
Another mode, when the first networking NW1 and the second networking NW2 frequency range utilization rate are higher than time to a certain degree, data transferring system 200 will close the higher application of frequency range utilization rate by coercion action device UE1 to UEX-1, as audio-visual crossfire formula, the first networking NW1 and the second networking NW2 is made to hold more multi-user.
But above-mentioned frequency range adjustment mode, also can perform under the condition that networks to the first networking NW1 not detecting outside running gear UEX, that is running gear UE1 to UEX-1 within the scope of networking can active accommodation its use frequency range.For example, running gear UE1 to UEX-1 links to the first networking NW1, and each running gear UE1 to UEX-1 all performs at least one application, and therefore each running gear UE1 to UEX-1 can use frequency range by a corresponding running gear.When data transferring system 200 obtains the use frequency range summation of these running gears, and when judging that this uses frequency range summation more than a reservation value, first networking NW1 and/or the second networking NW2 can broadcast the message of a frequency range restriction in running gear UE1 to UEX-1, to make in running gear UE1 to UEX-1 all or the use frequency range of the running gear of part lower than a preset limit, be no more than this reservation value to make the use frequency range summation of running gear UE1 to UEX-1.
The present embodiment is according to above-mentioned different frequency range condition and judge formula, and data transferring system 200 will perform different frequency range allocation strategies to running gear UE1 to UEX.But the present invention is not as limit, in other embodiments, except can utilizing different judgement formulas, the judgement formula of above-described embodiment
or
Also can change and be
And
Wherein Th1 and Th2 is two preset values, and two preset value Th1 and Th2 can be equal or unequal numerical value.And introduce the design flexibility that preset value Th1 and Th2 can increase the frequency range distribution of data transferring system 200.In addition, as shown in Figure 3, the running gear UE1 to UEX-1 originally within the scope of networking can also carry out frequency range return by the resource management apparatus RM being linked to the first networking NW1 and the second networking NW2.Running gear UE1 to UEX-1 can regularly return frequency range to resource management apparatus RM and be distributed by its frequency range and be registered in resource management apparatus RM.When outside running gear UEX wish line is in the first networking NW1 and the second networking NW2, also can return frequency range to resource management apparatus RM and be distributed by the frequency range of itself be registered in resource management apparatus RM, and the frequency range situation of outside running gear UEX and distribution can be broadcast to running gears all within the scope of networking by resource management apparatus RM, and can according to above-mentioned condition, the frequency range of house steward's running gear UE1 to UEX is coordinated.
In sum, the present invention discloses a kind of data transferring system, and its concept, for utilizing multiple heterogeneous networking, distributes the use frequency range of all executory applications.Because the resource (frequency range) at multiple heterogeneous networking is used simultaneously, therefore single networking interface can only be used relative to the design of tradition networking, data transferring system of the present invention is except can significantly except promoting transmission rate, simultaneously also by the use frequency range optimization of all executory applications, allow user before use scape application time can obtain better line quality.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
