Embodiment two:
The embodiment of the invention two is on the basis of embodiment one, except the load capacity to the transmitting terminal access network detects, can also detect the equipment performance of transmitting terminal and other network performances of the current access network of transmitting terminal, with the purpose of the wireless transmission stability that reaches further lifting file.
The wireless transmission process of supposing file in the present embodiment is by the process of portable terminal to webserver transfer files, and as shown in Figure 2, the method schematic diagram for the embodiment of the invention two may further comprise the steps:
Step 201: portable terminal detects has new file to send task in the task list.
The relevant parameter that can comprise file to be sent in the file transmission task is as file type (text type, video type or audio types etc.) and file size etc.
Step 202: portable terminal is gathered the signal strength signal intensity of current access network, and predicts the signal strength signal intensity of current access network in the very first time section according to collection result.
Wherein, very first time section is the time period that is used for transfer files, and its length is the first setting duration, and the length of the very first time section in this step can be set according to transmission demand.
Because wireless network substantially radially, signal strength signal intensity is that ladder successively decreases around the middle mind-set with the base station, so after portable terminal is gathered network signal intensity in a period of time, can roughly dope the signal strength signal intensity in the following very first time section.Because the following very first time section of prediction is the time that is used for transfer files, whether the signal strength signal intensity that can tentatively judge network in the following very first time section by predicting the outcome meets the requirement of file transfer, thereby whether decision starts or continue the file transfer in following very first time section.For example, when the setting duration of very first time section was 1 minute, portable terminal was predicted signal strength signal intensity in following 1 minute by gathering current signal intensity.

Step 204: portable terminal detects its other resources occupancy, and the resource occupation amount that detects is compared with setting stock number, if the resource occupation amount of portable terminal less than setting stock number, then execution in step 205; Otherwise, execution in step 213.
In this step, state detects in the time of need be to portable terminal not busy, carries out file during state when requiring portable terminal to be in the spare time, is in busy state to avoid portable terminal, can't correctly carry out the problem of file transfer.
The performance parameter of state when the resource occupation amount of portable terminal includes but not limited to that the CPU occupancy, EMS memory occupation amount of portable terminal etc. is can reflect mobile terminal not busy.
Step 205: portable terminal detects the load capacity of current access network, and the load capacity that detection is obtained and the offered load amount of setting compare, if detect the load capacity that obtains less than the offered load amount of setting, then execution in step 206; Otherwise, execution in step 213.
In the step 203～step 205 of present embodiment two, portable terminal detects network and the performance of self respectively, the embodiment of the invention two is not limited to the enforcement order of above-mentioned steps 203～step 205, and the status detection order can sort arbitrarily during signal strength signal intensity, offered load amount and portable terminal not busy.More preferably, status detection detects prior to the offered load amount during with portable terminal not busy, the purpose of doing like this is: portable terminal detects fairly simple to the soft hardware equipment of self, do not need to carry out relatively complicated offered load amount if portable terminal is in busy state and detect, to save the resource of portable terminal.
Step 206: portable terminal judges that whether the network of current access has distributed bandwidth resources for this document transmission process, if then execution in step 207; Otherwise, execution in step 213.
Step 207: portable terminal judges whether to have set up the radio communication channel that is used to carry transfer files with the network of current access, if then execution in step 208; Otherwise portable terminal is set up radio communication channel to the network requests of current access, when radio communication channel is set up successfully, and execution in step 208; Otherwise, execution in step 213.
Step 208: when portable terminal arrives in very first time section, by the radio communication channel of setting up, to webserver transfer files.
Step 209: in very first time section, portable terminal continues the signal strength signal intensity of current access network is gathered, and according to collection result the signal strength signal intensity of current access network in second time period is predicted.
Second time period here is a very first time section adjacent time intervals afterwards, and the length of second time period is the second setting duration.The length of the very first time section and second time period can be the same or different, and generally speaking, for the stability that guarantees to transmit, the very first time section and second time period are set to equal length.
Step 210: portable terminal judges whether the interior signal strength signal intensity of second time period of prediction is higher than setting signal intensity, if then execution in step 211; Otherwise, execution in step 212.
Step 211: portable terminal judges whether file transmits to finish after the very first time, section transmission was finished, if, the then wireless transmission process of file end; Otherwise, continuation is transfer files in second time period, and redirect carries out the scheme be similar to step 209, promptly in current slot during transfer files, signal strength signal intensity to next time period detects simultaneously, is to continue transmission or stop transmission according to testing result.
Step 212: in very first time section after the end of transmission, execution in step 213.
Step 213: wait for the unit duration that is provided with, and will wait for that number of times adds N judge whether the cumulative frequency of waiting for reaches maximum times (as 10 times), if then the wireless transmission process of file finishes; Otherwise, jump to step 202.
Be provided with when initial and wait for that number of times is 0, bide one's time no matter step 201 to the arbitrary reason in the step 212 jumps to step 213 back etc., all need the wait number of times is added N, the N value here is a positive number, is 1 as value.
Method by the embodiment of the invention two, before the wireless transmission of carrying out file, whether transmitting terminal has distributed bandwidth resources to signal strength signal intensity, its other resources occupancy, the load capacity of current access network, the network of current access network for this file transfer, when above-mentioned condition all satisfies, and then carry out file transfer by radio communication channel existing or that set up, guarantee in the transmission course of file, the performance of transmitting terminal and wireless network state can satisfy the needs of file transfer, improve the reliability and stability of file wireless transmission.The embodiment of the invention two also is not limited to select transmitting terminal to the signal strength signal intensity of current access network and one or two testing conditions in its other resources occupancy, with the load capacity of the testing conditions selected and current access network together as the basis for estimation of file transfer.

Step 301: transmitting terminal receives that the file from receiving terminal issues request, determines to carry out file transfer.
Step 302: receiving terminal is notified to transmitting terminal with the load capacity of self current access network.
In this step, receiving terminal can be carried at the load capacity of self current access network file and issue and be notified to transmitting terminal in the request, also can be after transmitting terminal receives that file from receiving terminal issues request, reply alternately with receiving terminal, receiving terminal is receiving that replying of transmitting terminal dynamically reports the load capacity of self access network after mutual.
Step 303: transmitting terminal compares load capacity and the setting network load capacity of receiving, if the load capacity that receives less than the setting network load capacity, then execution in step 304; Otherwise, execution in step 305.
It is in order to determine whether the current access network of receiving terminal is in light-load state, if the network of the current access of expression receiving terminal can be supported this document transmission process probably that transmitting terminal compares the load capacity received and setting network load capacity; Otherwise the load of the current access network of receiving terminal is bigger, can not support correctly that the possibility of file transfer is also bigger.
Step 304: the network of transmitting terminal by self current access carries out the wireless transmission of file to receiving terminal, realizes transmission course.
Step 305: transmitting terminal is to the receiving terminal transfer files, and jumps to step 302, and transmitting terminal regains the load capacity of the current access network of receiving terminal.
After step 305 jumps to step 302, the mode that transmitting terminal regains the load capacity of the current access network of receiving terminal can only be after replying alternately with receiving terminal, the load capacity that receiving terminal dynamically reports, and can not be that file issues the load capacity of carrying in the request.
With embodiment one similarly, receiving terminal among the embodiment three is if portable terminal, along with moving of receiving terminal, the load capacity that at every turn is notified to transmitting terminal in the step 302 may be the load capacity of same sub-district, also may be the load capacity of the different districts of same type network, also may be the load capacity of the sub-district of different type network.
Scheme by the embodiment of the invention three, transmitting terminal detected the load capacity of receiving terminal access network before the wireless transmission of carrying out file, when being in underload, the network of determining receiving terminal carries out file transfer, avoided because the network of receiving terminal can't be the receiving terminal allocation of transmission resources when being in busy state, cause receiving terminal can't correctly receive the problem of file, improved the stability of file wireless transmission.
