Refer to Fig. 4, it is that mobile phone and base station utilize the schematic diagram that flows to configuration interface management data transmission path.Between mobile phone 11 and base station 13, can utilize to flow to configuration interface data packet is operated to control, flow control etc.
The configuration interface 111 that flows to of mobile phone 11 comprises: directly carry out the ICP/IP protocol stack 116a, tunnel 115,3G physical channel 113 of transfer of data, ICP/IP protocol stack 116b, the WiFi physical channel 114 of collocation 3G physical channel 113 with application program 112, and the ICP/IP protocol stack 116c of collocation WiFi physical channel 114.Wherein, when mobile phone 11 uploading data, the uploading data of application program 112 is first encapsulated as the data packet of the TCP/IP form corresponding with mobile phone 11 by ICP/IP protocol stack 116a.Then, by the tunnel 115 of mobile phone 11, those data packets are shunted.The tunnel 115 of mobile phone 11 can be sent to uploading data 3G physical channel 113 and WiFi physical channel 114.When mobile phone 11 downloading data, tunnel 115 can receive downloading data from the 3G of mobile phone 11 physical channel 113 and the WiFi physical channel 114 of mobile phone 11.
The configuration interface 131 that flows to of base station 13 comprises: carry out the ICP/IP protocol stack 136a, tunnel 135,3G physical channel 133 of transfer of data, ICP/IP protocol stack 136b, the WiFi physical channel 134 of collocation 3G physical channel 133 with internet 15, and the ICP/IP protocol stack 136c of collocation WiFi physical channel 134.Wherein, when mobile phone 11 uploading data, the tunnel 135 of base station 13 can receive the uploading data that mobile phone 11 spreads out of from 3G physical channel 133 and WiFi physical channel 134.When mobile phone 11 downloading data, the tunnel 135 of base station 13 can, by the data packet of the downloading data being received by internet 15, be sent to the 3G physical channel 133 of base station 13 and the WiFi physical channel 134 of base station 13.
Tunnel 115 has an IP address (that is, mobile phone address (Addr_VT_UE)).For the situation of not using network address translation (Network Address Translation, referred to as NAT), other users of internet 15 can Direct Recognition mobile phone address (Addr_VT_UE).Even in the situation of using network address translation, mobile phone address (Addr_VT_UE) can normal conversion be also external address, do not affect the use of upper level applications.There is general ICP/IP protocol stack 116a on the upper strata of tunnel 115, uses the data of ICP/IP protocol sending and receiving types of applications program according to general fashion.
WiFi physical channel 114 and the 3G physical channel 113 of mobile phone 11 have an IP address that inside is custom.That is, the WiFi address (Addr_WF_UE) of mobile phone and the 3G address (Addr_3G_UE) of mobile phone.WiFi physical channel 114 and 3G physical channel 113 arrange in pairs or groups separately ICP/IP protocol stack 116c, a 116b.ICP/IP protocol stack 116c, the 116b of WiFi physical channel 114 and 3G physical channel 113, the priority in local routing table is lower than the ICP/IP protocol stack 116a of tunnel 115.
Therefore, 3G address (Addr_3G_UE) application programs 112 of the WiFi address (Addr_WF_UE) of mobile phone and mobile phone is stealthy.For other all nodes beyond base station 13, the WiFi address (Addr_WF_UE) of mobile phone and the 3G address (Addr_3G_UE) of mobile phone are also stealthy.In other words, the WiFi address (Addr_WF_UE) of mobile phone and the 3G address (Addr_3G_UE) of mobile phone communicating by letter for mobile phone 11 and base station 13 only.
After the tunnel 115 of mobile phone is enabled, because ICP/IP protocol stack 116c, the priority of 116b in local routing table are lower, ICP/IP protocol stack 116c, 116b can not directly receive data from application program 112, can only receive the data packet transmitting via tunnel 115.
Behind the data packet that the application program 112 that receives tunnel 115 transmits and the IP address of receiving terminal, according to the allocation of parameters that user defines or dynamic calculation draws, the data packet of part is sent to 3G passage 12 via ICP/IP protocol stack 116b and 3G physical channel 113.And, the data packet of part is sent to WiFi passage 14 via ICP/IP protocol stack 116c and WiFi physical channel 114.
Base station 13 flow to configuration interface 131, with mobile phone 11 to flow to configuration interface 111 similar and corresponding.What only take mobile phone 11 herein flows to configuration interface 111 as example, and what base station 13 was no longer described in detail in detail flows to configuration interface 131.
The shunt ratio that 115 pairs of data packets of tunnel are shunted institute's reference can be a definite value, or a numerical value of dynamically adjusting.Shunt ratio can be determined by mobile phone 11 or base station 13.About setting and the control mode of shunt ratio, can be applied voluntarily by this case person of an ordinary skill in the technical field, therefore do not repeat.
When shunt ratio is fixing preset value, can provide one to set the page by mobile phone 11, allow user set voluntarily.Or mobile phone 11, when connecting at the beginning, judges after the Channel Bandwidth of 3G passage 12 and WiFi passage 14 initial value calculating.Afterwards, 13 of mobile phone 11 and base stations, just using this initial value as default shunt ratio.
Moreover, because the WiFi passage 14 of same base station 13 may provide branched mobile phone, use, the practice of the power to make decision of dynamically adjusting shunt ratio being given to mobile phone 11, can make mobile phone 11 appropriate according to the applicable shunt ratio of indivedual state computation.Further, shunt ratio also can be arranged in pairs or groups and be adjusted coefficient use.Subsequent embodiment will illustrate, collocation is adjusted coefficient and used a kind of practice of shunt ratio.
Refer to Fig. 5, it is the flow chart of communication means of the present invention.First, in base station, 13 set up and use the TCP of 3G passages 12 to be connected (step S11) with 11 of mobile phones.In the TCP of 3G Path Setup connects, using base station 13 as user side (client), using mobile phone 11 as server (server).
Then the TCP that, judges 3G passage connects whether to be successfully established (step S12).If judgment result is that of step S12 is negative, flow process finishes.If step S12 judgment result is that certainly, in base station, 13 TCP that further set up use WiFi passages 14 with 11 of mobile phones are connected (step S13).During the TCP setting up at WiFi passage 14 connects, using mobile phone 11 as user side (client), using base station 13 as server (server).
Whether the TCP connection that judges WiFi passage 14 thereafter, sets up (step S14) smoothly.If judgment result is that of step S14 is negative, between mobile phone 11 and base station 13, just only carry out transfer of data (step S17) with the TCP connection of 3G passage 12.If step S14 judgment result is that certainly, further according to allocation of parameters and distribute data package, and then make data packet can utilize the TCP of WiFi passage 14 to connect, the TCP of 3G passage 12 connects to transmit data packet (step S15) simultaneously.

Mobile phone 11 is according to the stem of data packet, obtains the IP address of the 3G passage of base station 13 (hereinafter to be referred as the 3G address of base station) (Addr_3G_BS) (step S305).Mobile phone 11 also stores the WiFi address (Addr_WF_BS) of base station and the 3G address (Addr_3G_BS) (step S306) of base station.
Mobile phone 11 utilize 3G passage 12 to base station 13 passback a confirmation, mobile phone 11 is also simultaneously by the IP address (Addr_WF_UE) of the WiFi passage 14 of mobile phone 11, and the 3G address (Addr_3G_UE) of mobile phone is sent to base station 13 (step S307).
Corresponding, base station 13 receives the confirmation that mobile phone 11 returns, and the 3G address (Addr_3G_UE) of mobile phone and the WiFi address (Addr_WF_UE) (step S206) of mobile phone.Thereafter, base station 13 will store the 3G address (Addr_3G_UE) of mobile phone and the WiFi address (Addr_WF_UE) (step S207) of mobile phone.So far during step, the 3G passage 12 that mobile phone 11 and base station are 13 has been set up, so first stage I finishes.When the first stage, I finished, mobile phone 11 has been obtained the WiFi address (Addr_WF_BS) of base station, and the also corresponding WiFi address (Addr_WF_UE) of obtaining mobile phone 11, base station.The WiFi address that these correspondences obtain, will, when second stage II, connect for setting up second TCP.
Mobile phone 11 and base station 13, after 3G passage 12 is set up first TCP and is connected, not necessarily can be set up second TCP at WiFi passage 14 immediately and connect.Now, base station 13 will maintain and transmit at set intervals information to mobile phone 11 at 3G passage 12, make mobile phone 11 be confirmed still normal operation of 3G passage 12.For example: every S second, base station 13 connects to mobile phone 11 and sends heartbeat messages (for example: " Live ") (step S208) by the TCP of 3G passage 12.Corresponding, mobile phone 11 utilizes heartbeat message to safeguard that the TCP on 3G passage 12 connects (step S308).
Base station 13 continues to send the object of heartbeat message, is the activity that the TCP in order to be maintained on 3G passage 12 connects.When mobile phone 11 for example, does not receive heartbeat message through S second (: 30 seconds), can judge to be accordingly connected with the TCP of 13 of base stations to produce different shape.Now, can attempt on 3G passage, setting up once again mobile phone 11 is connected with the TCP of 13 of base stations.
In second stage II, mobile phone 11 first detects WiFi signal (step S309).Afterwards, mobile phone 11, by the checking of the wireless router at WiFi passage, is obtained an IP address (step S310).Distribute the IP address give mobile phone to be the WiFi address (Addr_WF_UE) of mobile phone herein.
Mobile phone 11 is by WiFi passage 14, and to base station, 13 communication port numbers 5388 sends a TCP connection request (step S311).The communication port numbers 5388 of base station 13 detects the TCP connection request (step S208) that mobile phone 11 utilizes WiFi passage 14 to send.
If the TCP of WiFi passage 14 connects, set up unsuccessfully, flow process comes back to step S308.If the TCP of WiFi passage 14 connects, be successfully established, confirmation (step S209) is returned to mobile phone 11 in base station 13; And mobile phone 11 receives the confirmation (step S312) of returning by WiFi passage 14 base station 13.Now, second stage II finishes.
Afterwards, communication system starts to enter and uses 3G passage 12 to be connected with the TCP of WiF passage 14 the phase III III that transmits data packet simultaneously.In 3G passage 12, the frequency range that mobile phone 11 can use is fixing.In other words, be jointly connected to the number of mobile phone 11 quantity of same base 13, can't affect the frequency range of the spendable 3G passage of mobile phone 11.
On the other hand, in WiFi passage 14, the frequency range that mobile phone 11 can use can be according to the mobile phone quantity of sharing base station 13 and is different.In brief, when mobile phone 11 quantity that are jointly connected to same base station 13 are when more, the frequency range of the WiFi passage 14 that each mobile phone 11 can be assigned to is also less.Related, mobile phone 11 transmits the shunt ratio of data according to 3G passage 12 and WiFi passage 14, also can therefore be affected.
WiFi passage 14 is also passed through in base station 13, and the mobile phone quantity (NUM_WF_UE) that transmission is connected with base station 13 by WiFi passage 14 is to mobile phone (step S210).
Mobile phone 11 receives the mobile phone quantity (NUM_WF_UE) (step S313) being connected with base station 13.Then, mobile phone 11 is according to the parameters such as intensity of the standard of two physical channels and signal, and calculated data package is in the allocation of parameters (step S314) of two passages.Allocation of parameters can comprise shunt ratio (Pi) and adjust coefficient (T) etc.
Mobile phone 11 is 13 transmission allocation of parameters (step S315) to base station.Base station 13 receives after allocation of parameters (step S211), by the 3G address (Addr_3G_UE) of the WiFi address (Addr_WF_UE) of mobile phone, mobile phone, and the corresponding relation of allocation of parameters is stored in (step S212) in user's table of comparisons.Thereafter, 13 of mobile phone 11 and base stations, will carry out flow-dividing control (step S4) to the transmission of data according to allocation of parameters.About the further details of step S4, can be referring to the explanation of Fig. 7, Fig. 8.
Refer to Fig. 7, it is dynamically to adjust the schematic diagram that flow-rate ratio is set.First calculate the bare flow ratio P0 (step S51) of two passages.According to 820.11g/n standard, frequency range (BW_WF) the frequency range BW_WF of Hui Shiyige unit of mobile phone 11 spendable radio area networks
unitmultiple.In other words, when mobile phone 11 uses WiFi passage 14, the minimum frequency range of spendable radio area network (min (BW_WF)) is equivalent to the frequency range (BW_WF of unit
unit).According to minimum frequency range (min (BW_WF)=BW_WF
unit) with the frequency range (BW_3G) of the spendable 3G passage 12 of mobile phone 11, can calculate bare flow ratio (P0) by following formula:
P0＝BW_WF
unit/BW_3G
Then calculate the shunt ratio (Pi) (step S52) of WiFi passage 14.The mode that shares frequency range due to 802.11 employings is transmitted data, and current frequency range is the Integer n times of minimum frequency range min (BW_WF).Moreover the quantity (NUM_UE_WF) of jointly using WiFi passage 14 to be connected to the mobile phone 11 of base station 13 also can affect and also affect shunt ratio (Pi).Therefore, the computational methods of the shunt ratio of WiFi passage 14 (Pi) are:
Pi＝n*P0/NUM_UE_WF
When mobile phone 11 is mobile rapid within the scope of WiFi, will there is acute variation in the intensity of the WiFi signal that base station 13 provides, thereby impact is in following length.In order to predict more accurately ensuing shunt ratio (Pi), the present invention will calculate and adjust the practice that coefficient (T) (step S55) is adjusted volume of transmitted data.Can be further referring to the flow chart shown in Fig. 8 about adjusting the account form of coefficient (T).Thereafter, mobile phone 11 will store shunt ratio (Pi) and adjust coefficient (T) (step S57).
Refer to Fig. 8, it is to calculate the flow chart of adjusting coefficient.This figure is further illustrating of Fig. 7 step S55.
First utilize signal strength signal intensity An arrayed recording and upgrade recent signal to noise ratio (step S551).For example: utilize the signal to noise ratio (SNR[t]) of t time point to upgrade the signal to noise ratio of (t-1) time point originally storing (SNR[t-1]); By the signal to noise ratio of current time point (SNRnow) for upgrading the signal to noise ratio (SNR[t]) of t time point.Step S551 can represent by following formula:
SNR[t-1]＝SNR[t]，
SNR[t]＝SNRnow
Next calculates the variation (step S552) of each time point signal to noise ratio.For example: by the signal to noise ratio of t time point (SNR[t]) deduction at the signal to noise ratio of (t-1) time point (SNR[t-1]).Step S552 can represent by following formula:
ΔSNR[t-1]＝SNR[t]-SNR[t-1]
Then, according to signal to noise ratio at t time point, change (Δ SNR[t]), and in the signal to noise ratio of (t-1) time point, changing (Δ SNR[t-1]), prediction changes (Δ SNR[t+1]) (step S553) in the signal to noise ratio of (t+1) time point.Step S553 can represent by following formula:
ΔSNR[t+1]＝2*ΔSNR[t]-ΔSNR[t-1]
Thereafter, the signal to noise ratio at (t+1) time point that draws according to prediction changes (Δ SNR[t+1]), and prediction is in the signal to noise ratio of (t+1) time point (SNR[t+1]) (step S554) with signal to noise ratio at t time point (SNR[t]).Step S554 can represent by following formula:
SNR[t+1]＝SNR[t]+ΔSNR[t+1]
Then, according to the signal to noise ratio of (t+1) time point (SNR[t+1]) and the comparison of each signal-noise ratio threshold, determine to adjust coefficient (T) (step S555).Step S555 is further divided into three kinds of situations in response to the signal to noise ratio snr [t+1] of (t+1) time point by the calculating of adjusting coefficient (T): signal strengthens rapidly, signal attenuation is rapid, signal intensity is little.
Define several signal-noise ratio thresholds herein, for example: subordinate's signal-noise ratio threshold (thres (i+1)), current signal-noise ratio threshold (thres (i)), prime signal-noise ratio threshold (thres (i-1)), front two-stage signal-noise ratio threshold (thres (i-2)).These signal-noise ratio thresholds are for the size of auxiliary judgment signal to noise ratio.Wherein, compared with the signal-noise ratio threshold of rear class, be greater than the signal-noise ratio threshold compared with prime.For example: thres (i+1)=11, thres (i)=10, thres (i-1)=9, thres (i-2)=8.
First judge whether signal to noise ratio at (t+1) time point (SNR[t+1]) is greater than current signal-noise ratio threshold (thres (i)) (step S555a).If step S555a judgment result is that certainly, represent that the intensity of WiFi signal strengthens rapidly (S555b).Now according to following formula, calculate and adjust coefficient (T):
T＝[SNR(t+1)-thres(i)]/[thres(i+1)-thres(i)]
Due to SNR (t+1) >thres (i+1), relatedly make to adjust coefficient (T) and be greater than 1.This kind of result of calculation representation signal strengthens rapidly, now by the data volume improving via 14 transmission of WiFi passage.
If judgment result is that of step S555a is negative, further compare the signal to noise ratio (SNR (t+1)) of (t+1) time point and the size (step S555c) of prime signal-noise ratio threshold (thres (i-1)).If (t+1) signal to noise ratio of time point (SNR[t+1]) is less than prime signal-noise ratio threshold thres (i-1), representation signal decay is (step S555d) rapidly.Now according to following formula, calculate and adjust coefficient (T):
T＝[SNR(t+1)-thres(i-1)]/[thres(i-1)-thres(i-2)]
Because the signal to noise ratio of (t+1) time point (SNR[t+1]) is less than prime signal-noise ratio threshold (thres (i-1)).That is, SNR[t+1] <thres (i-1).And prime signal-noise ratio threshold (thres (i-1)) is greater than front two-stage signal-noise ratio threshold (thres (i-2)).That is, thres (i-1) >thres (i-2), the adjustment coefficient (T) herein calculating is less than 1.Now by the data volume reducing via 14 transmission of WiFi passage.
Moreover if (t+1) signal to noise ratio of time point (SNR[t+1]) is between prime signal-noise ratio threshold (thres (i-1)) and current signal-noise ratio threshold (between thres (i)), representation signal changes little (step S555e).That is, thres (i-1) <SNR[t+1] <thres (i).Now will adjust coefficient (T) and be set as 0, representative is not adjusted at the data volume of WiFi passage 14 transmission.
Refer to Fig. 9, its be mobile phone and base station in the phase III, uploading data is carried out to the flow chart of triage operator.For simplified illustration, suppose before this flow process starts herein, mobile phone 11 is connected all and has set up with two TCP of 13 of base stations, and hypothesis base station 13 has obtained the WiFi address (Addr_WF_UE) of mobile phone address (Addr_VT_UE), mobile phone, the 3G address (Addr_3G_UE) of mobile phone, shunt ratio (Pi) and adjustment coefficient (T).
First tunnel 115 receives the uploading data (step S61) that application program 112 transmits.Mobile phone 11 transmit uploading datas to base station 13 process, can further divide into initial transfer phase, and general transfer phase.When mobile phone 11 is when using binary channels function at the beginning, based on its mobile status unsettled considering also, use and adjust coefficient (T) collocation shunt ratio (Pi) and determine shunting mode.
When initial transfer phase, the uploading data of mobile phone 11 can transmit (step S63) with shunt ratio (Pi) in WiFi passage 14,3G passage 12 according to adjusting coefficient (T).About further illustrating of step S63, please refer to the flow chart of Figure 10.
On the other hand, when general transfer phase, the uploading data of mobile phone 11 can transmit according to shunt ratio (Pi).First, the individual count device (step S65) that initialization shunting algorithm is used.For example: will send data packet sum (PK_Sum) and be set as 0; And binary channels is sent to alternate frequency (SW) be set as 1.
Secondly, according to shunt ratio (Pi) at binary channels forwarding data (step S66).About further illustrating of step S66, please refer to the flow chart of Figure 11.Then, judge whether to finish twin-channel transfer function (step S67).If step S67 judgment result is that flow process finishes certainly.If judgment result is that of step S67 is negative, increase alternate frequency (step S68).That is, SW=SW+1.
Judge whether alternate frequency SW is greater than default accumulative total numerical value (SW
thres) (for example: SW
thres=100) (step S69).If so, re-execute step S65; Otherwise re-execute step S66.Default accumulative total numerical value (SW provided herein
thres), the precision whether meeting meets shunt ratio (Pi) really according to reality transmission data determines.
For example: if wish, mobile phone 11 and base station 13 utilize the actual ratio of the data packet number that WiFi passage 14 and 3G passage 12 transmit simultaneously, and the precision that meets shunt ratio (Pi) is one thousandth, will preset totally numerical value and be set as 1000.In like manner, can be according to the actual ratio of acceptable volume of transmitted data, and the error degree between shunt ratio (Pi), determine default accumulative total numerical value (SW
thres).
Refer to Figure 10, it is in binary channels, to transmit the flow chart of data according to adjusting coefficient and shunt ratio.First setting alternate frequency (SW) is 1 (step S631), and transmits a data packet (step S633) at 3G passage 12; Then at WiFi passage 14, transmit N data packet (step S635).The number N of the data packet wherein, transmitting at WiFi passage 14 is defined as: N=SW*Pi+T.
Hold, every use 3G passage 12 transmits a data packet, just relatively at WiFi passage 14, transmits N data packet.In general, the number N of the data packet transmitting by WiFi passage 14, can be more than the number of the data packet transmitting by 3G passage 12.
Judge whether WiFi passage 14 successfully transmit data packet, judge N≤1 (step S639) thereafter.If step S639 judgment result is that certainly, finish the flow process at initial transfer phase.
On the other hand, if judgment result is that of S639 is negative, just further add up alternate frequency (SW) (that is, SW=SW+1) (step S637) and re-execute step S633.If judgment result is that of step S639 is negative, representative is not used WiFi passage 14 to transmit data packet.This kind of phenomenon may stem from, and the available WiFi passage 14 frequency ranges adjustment coefficient (T) less and/or that calculate that mobile phone 11 is assigned to is the situation of negative.Now, the tunnel 115 of mobile phone 11 maintains to use with 3G passage 12 and transmits data packet.
Refer to Figure 11, it is according to shunt ratio, in binary channels, to transmit the flow chart of data.First at 3G passage 12, transmit 1 data packet (step S661); Then at WiFi passage 14, transmit the individual data packet of int (Pi) (step S663).Wherein, the result of calculation of its integer part is got in int (Pi) representative to shunt ratio (Pi).According to ratio, maintaining parameter (IF_P) judges whether with WiFi passage 14, to transmit data packet (step S665) again.Step S665 further comprises following steps:
Calculating ratio maintains parameter (IF_P) (step S665a).Ratio maintains parameter (IF_P) and can calculate according to following formula:
IF_P＝int(Pi-int(Pi))×SW)-int(Pi-int(Pi))×(SW-1))
Due to shunt ratio (Pi) integer not necessarily, the ratio of the present invention further provides maintains parameter (IF_P), for making the actual ratio between the quantity of the quantity of the data packet that the WiFi passage 14 of multiple averaging transmits and data packet via 12 transmission of 3G passage, can meet shunt ratio (Pi).
For example: supposing in the situation that shunt ratio (Pi) is 1.3, during front transmission for twice, is all to transmit a data packet by 3G passage 12; And transmit a package by WiFi passage 14.In addition,, when transmitting for the third time, by 3G passage 12, transmit a package; And transmit two data packets by WiFi passage 14.
Then judge that ratio maintains parameter (IF_P) and whether is more than or equal to 1 (step S665b).If ratio maintains parameter, (IF_P) is more than or equal to 1, at WiFi passage 14, transmits a data packet (S665c) again; Otherwise stop at WiFi passage 14 and transmit data packet (step S665d).
During practical application, may there is branched mobile phone 11 to be connected to base station 13 simultaneously.According to the binary channels annexation with branched mobile phone foundation, a user's table of comparisons can be safeguarded in base station 13.In user's table of comparisons, the mobile phone 11 being connected with base station 13 for each, base station 13 will record the 3G address (Addr_3G_UE) of its title (or identification code), mobile phone address (Addr_VT_UE), mobile phone, fields such as the WiFi address (Addr_WF_UE) of mobile phone, shunt ratios (Pi).
When 13Zi internet, base station 15 receives after the Download Info of mobile phone 11, just follow the stored allocation of parameters corresponding with each mobile phone to transmit Download Info.For example: data packet is transmitted to mobile phone A according to the corresponding allocation of parameters A1 of mobile phone A, A2 in base station 13; And data packet is transmitted to mobile phone B etc. according to the corresponding allocation of parameters B1 of mobile phone B, B2 in base station 13.
Moreover, if base station 13 cannot inquire the virtual ip address of mobile phone C in user's table of comparisons, represent that mobile phone C does not open the diverter function of 3G passage 12 and WiFi passage 14.Now, the tunnel 115 of base station 13 does not process, and the path setting according to mobile phone C (for example: use separately WiFi passage 14 or use separately 3G passage 12) transmits data packet.
Communication system of the present invention, arranges and flows to configuration interface respectively at mobile phone and base station.Flow to configuration interface and can utilize C, Java to write, the mode of installing with software arrange in pairs or groups mobile phone and base station use.Therefore, can't increase the hardware production cost of mobile phone and base station.Moreover, even if the operating system of online passage, mobile phone/base station, actual collocation application program change, still applicable to the communication means of this case.
The present invention can use WiFi passage 14 and 3G passage 12 simultaneously, can improve the transmitting bandwidth between base station 13 and mobile phone 11.Moreover, the problems such as the interruption that the present invention can also avoid producing because of the switching of transfer of data between two passages, shake.Accordingly, while adopting communication means of the present invention, the reliability of transfer of data can significantly promote.Moreover the present invention can be widely used in various operating systems (such as Android, Linux, Windows Phone etc.).In addition, portable apparatus also can adopt different operating systems from server.For example: portable apparatus is used Android operating system, server uses Linux operating system.
Subsidiary one carries, if base station 13 itself is the simple referral purposes as 11 of internet 15 and mobile phones, just do not need to provide address, base station (Addr_VT_BS).On the other hand, once base station, 13 have corresponding address, base station (Addr_VT_BS), and the intercommunication that can be further used as between base station 13 and mobile phone 11 is used.For the purposes of referral, base station 13 can all be deleted the field before self-defined stem, only retains IP stem, TCP stem, data.
In this embodiment, suppose that the shunt ratio (Pi) between mobile phone 11 and base station 13 is the numerical value of a dynamic setting.Shunt ratio (Pi) is dynamically adjusted by the flowing to configuration interface 111 according to the state of network bandwidth of mobile phone 11.
In other application, the configuration interface 111 that flows to of mobile phone 11 also can be for different application programs, and the set-up function of different shunt ratio (Pi) is provided.For example: for the data relevant to the first application program, with the first sub-shunt ratio (Pi1), transmit; And, for the data relevant to the first application program, with the second sub-shunt ratio (Pi2), transmit.About whether further adopting sub-shunt ratio, and the deciding means of sub-shunt ratio, can by the those of ordinary skill of technical field described in this case, be replaced voluntarily and apply, repeat no more herein.
