Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of mobile phone sends big data under the WAP mode method, to keep network under the connection situation, to send data continuously and to support the data breakpoint transmission, improve transmitting efficiency and stability, save the GPRS network flow, overcome mobile phone sends big data under the WAP network connecting mode deficiency.
Mobile phone provided by the present invention sends the method for big data under the WAP mode, comprise data to be sent are divided into a plurality of cell data bags; Create interface channel, send described cell data bag one by one; After receiving the correct response message that receives of expression that server end returns, judged whether that remaining described cell data bag does not send, if, then keep interface channel not disconnect, directly initiate the request of the next described cell data bag of transmission; If not, then disconnect interface channel and point out the user to send success.
Preferably, before described method also is included in and sends described cell data bag, record the sequence number of the described cell data bag of current transmission.
Preferably, described method backs up described cell data bag before also being included in and sending described cell data bag, for making a mistake or the described cell data bag of network disconnection back repeating transmission.
Preferably, after described method also is included in and receives the response message that described server end returns, will send the protection timer and reset.
Preferably, if wherein described response message represents that server end correctly receives the packet that the user uploads, the memory source of monopolizing when once sending described cell data bag before then discharging, and reset passages connection status sign.
Preferably, if wherein described response message represents that server end receives mistake, disconnect and create interface channel after connecting again again and lay equal stress on and send described cell data bag, realize breakpoint transmission.
Preferably, in case wherein create the total degree that the number of times of interface channel surpasses restriction again, then finish whole process of transmitting, the corresponding error message of prompting user.
Preferably, the size of wherein said cell data bag is no more than 10KB.
Beneficial effect of the present invention is, a kind of transmission mechanism quick, stable relatively when sending mass data under the WAP network connecting mode can be provided.Simultaneously, at the narrow bandwidth in the GSM mobile handset, thereby the unstable characteristics that cause bust this easily of transmission adopt the breakpoint transmission function can well guarantee the stability of transmitting, and better save the GPRS flow.
Description of drawings
Fig. 1 is mobile phone of the present invention sends the method for big data under the WAP mode preferred embodiment.
Specific embodiment
Fig. 1 is mobile phone of the present invention sends the method for big data under the WAP mode preferred embodiment.It is example that present embodiment sends mail with mobile phone.As shown in Figure 1, before beginning to transmit data, need to create interface channel, the sign that resets and send, and total mail data is divided into the 10KB size is the cell data bag (step S101) of the upper limit.The cell data bag size here is rule of thumb to be worth and to decide, and when the general cell packet was excessive, the mobile phone end sends this cell data bag can take too much system time, causes system task to stop up easily, thereby influences the real-time response of other application.
The transmitting element packet, and the packet of this time transmission backed up (step S102).Judge whether correctly receiving element packet (step S103) of server.Particularly, when receiving the response message that server end returns, if this response message represents to receive mistake, judge then whether retransmit number of times surpasses restriction (step S105), if surpass restriction, then resend a packet, and the number of times (step S107) of record repeating transmission, surpass certain limitation and then finish whole process of transmitting (step S106), the prompting user sends failure.
For the number of times upper limit of retransmitting, the selected influence that needs to consider two aspect factors of its size, first gateway server (as the WAP of China Mobile server) holding time to each interface channel, general, gateway server can disconnect this passage by force after sending the data of 50KB, and returns HTTP 500 error codes, and the mobile phone end disconnects old interface channel in this case, and create new interface channel again, continue to retransmit a last packet; It two also can require the mobile phone end to retransmit this packet after to be upstream server ends to the packet that receives resolve failure, and the probability that general this situation occurs is not high, and whole process of transmitting considers that 3～5 surpluses get final product.
What receive when the mobile phone end is the response message that correctly receives the packet that the user uploads from the described server end of expression that server returns, and when for example correctly receiving answer back code, judges whether remaining data bag (step S104) to be sent in addition earlier.If be last packet, then close connection, finish whole process of transmitting (step S106), the prompting user sends and finishes; Otherwise keep to connect, the process of transmitting sign that resets begins to send next packet (step S102), until the transmission remaining data bag that finishes.
The E-mail service of mobile phone electronic mail service and computer is similar, and major function comprises the transmitting-receiving of Email, the setting of the management of address list, the management of annex, blacklist, the deletion of mail and classification etc.Because mobile phone end GPRS speed uplink is slow more many than downstream rate, the GPRS speed uplink of mobile phone end becomes the key factor that the restriction e-mail applications is popularized at the 2.5G mobile phone.Use the method in the present embodiment, under the same hardware environment, when mobile phone used this method to send big data under the WAP mode, efficient improved more than 35%, makes that big data transmission procedure is more stable, and saved the GPRS flow.
Mobile phone disclosed by the invention sends data continuously in the method that sends big data under the WAP network mode under the situation of maintenance network connection passage, the breakpoint transmission function is provided, and retransmit a last packet during at server response timeout or network error, effectively raise the efficient of whole process of transmitting, further strengthen stability of data transmission, also well saved the GPRS network flow simultaneously.
The above only is preferred embodiment of the present invention, and the ordinary technical staff in the technical field of the invention is not in breaking away from spirit of the present invention and essence, when making various corresponding changes and distortion.Therefore, protection scope of the present invention is as the criterion when looking claims person of defining.
