Embodiment
To combine the accompanying drawing in the embodiments of the invention below, the technical scheme in the embodiments of the invention is carried out clear, intactly description, obviously, the embodiments described below only are the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of embodiments of the invention protection.
Embodiment one
The embodiment of the invention one provides a kind of management method of data transfer mode, and is as shown in Figure 1, comprising:
Concrete, local terminal equipment is monitored the signal quality of all data transfer modes.After receiving the identification information (for example IP address of equipment etc.) of the opposite equip. of user's input, local terminal equipment detects the corresponding opposite equip. of this identification information in all data transfer modes of its support, obtain the data transfer mode of the said opposite equip. of discovery.Local terminal equipment is also monitored the signal quality (for example signal strength signal intensity) of all data transfer modes of finding opposite equip., and the data transfer mode that is higher than preset value for signal quality is confirmed as the data available transmission means.For example; Local terminal equipment is the strong and weak and available bandwidth situation of signal of the various data transfer modes of monitoring in real time; When signal weakening when making that to a certain degree signal to noise ratio exceeds certain threshold value, local terminal equipment is rejected to this data transfer mode outside the data available transmission means automatically.
During local terminal equipment specified data transmission means according to certain collocation strategy; Transmission rate is maximum, fail safe is the highest, minimum data transfer mode perhaps consumes energy in order from the data available transmission means, to select for this collocation strategy; This collocation strategy can also be the priority specified data transmission means that is provided with according in advance; This priority can be provided with by the user in advance, and for example the user is provided with the Bluetooth transmission mode in advance and has limit priority, promptly at first uses bluetooth to carry out transfer of data; This moment, local terminal equipment need not compare according to transmission rate, fail safe or power consumption etc., but directly used bluetooth approach to carry out transfer of data.Need to prove; This collocation strategy can be by the user flexibility setting; For example the user can be arranged on different time sections and use different data transfer modes; Perhaps the fixedly use of user setup data transmission means when the data transfer mode of first cis-position can't be used the data transfer mode of second cis-position in proper order.The data available transmission means of local terminal equipment is an example with WiFi transmission, Infrared Transmission and Bluetooth transmission; If with the transmission rate is criterion; Local terminal equipment is selected access way according to attributes such as the type that transmits file, sizes; Preferentially select the WiFi transmission generally speaking, secondly Infrared Transmission, Bluetooth transmission at last.If file is less, local terminal equipment is selected the higher and more energy-conservation mode of fail safe automatically.If with the security performance is criterion, secondly infrared transmission of the preferential use of local terminal equipment be bluetooth and Wi-Fi.If with the power consumption situation is criterion, then need takes all factors into consideration the power characteristic of file size, bandwidth situation and each access way self and select to judge.
Step 103, when the switch data transmission means, the memory location of the data of last transmission before the local terminal equipment records is switched uses the data transfer mode after switching to proceed transfer of data according to this memory location.
Concrete, the local terminal monitoring of equipment needs when occupied less than threshold value or current data transmission means to current data transmission means signal quality, the switch data transmission means.In the embodiment of the invention, local terminal equipment writes down each data transmission information in the position corresponding with this data transfer mode when using current data transmission means transmission data, for example the position of current data transmission.When the switch data transmission means, local terminal equipment is searched the position of the data of transmitting at last before the switching of record, uses the data transfer mode after switching to proceed transfer of data from this position.
For example; Local terminal equipment is monitored the current data transmission means in real time; When the signal quality of this transmission means drops to this mode normal transmission data desired signal mass range when following (equipment connect break off); Perhaps when the higher application of other priority will take the bandwidth of this data transfer mode, perhaps when detecting the higher data transfer mode of priority, local terminal equipment judgment data transmission means need be switched.The data available transmission means of local terminal equipment is an example with WiFi transmission, Infrared Transmission and Bluetooth transmission still; In the embodiment of the invention; Transmission meanss such as infrared, bluetooth, Wi-Fi all have separately mistake and flow control protocol, and infrared deferring to selects to retransmit ARQ (Automatic Repeat reQuest, repeat requests automatically) agreement; Bluetooth then is the simple numbering ARQ agreement of not having, and these control protocols have all write down transmission and the reception feedback in the file delivery procedure.If under the specific transmission mode, certain Frame transmits failure, can continue to retransmit with this mode.If need carry out transmission means switches; Write down the feedback and the breakpoint location of the last transmit data frames; Carry out the selection of new data transmission mode according to the method for above-mentioned selection data transfer mode, select new data transfer mode after, pass remaining data from the breakpoint noted is continuous.
Embodiment two
The embodiment of the invention two provides a kind of management method of data transfer mode, and is as shown in Figure 2, comprising:
Support all that with local terminal equipment and opposite equip. infrared, bluetooth and Wi-Fi transmission means are example; Consider that opposite equip. possibly not open all transmission meanss (for example only having opened the Infrared Transmission mode), so local terminal equipment uses at first detected infrared mode notice opposite equip. to open its all transmission meanss.
The concrete realization refer step 101-103 of step 202-204.
Need to prove that the embodiment of the invention is that example describes with the transfer of data between local terminal equipment and the opposite equip. only, when local terminal equipment during simultaneously to a plurality of equipment transmission data, this method is suitable equally.For example; Local terminal equipment can basis confirm that with the monitoring result of the signal quality of a plurality of data transfer between devices modes a kind of data transfer mode of optimum and a plurality of equipment carry out transfer of data, also can be respectively with regard to each opposite equip. specified data transmission means.
In the embodiment of the invention; When local terminal equipment and opposite equip. carry out transfer of data; Local terminal equipment obtains available and data transfer mode opposite equip. according to the signal quality of all data transfer modes of finding opposite equip.; Further carry out transfer of data according to collocation strategy definite a kind of mode from the data available transmission means, and the position of the data of transmitting at last before record switches when needing the switch data transmission means, use the data transfer mode after switching to proceed transfer of data from this position; Guarantee the integrality of transfer of data; Data transfer mode when initial sum is switched need not artificial selection, improves user experience, and guarantees reliability of data transmission during the switch data transmission means.
