Several stages has been experienced in the development on wireless mobile network road, that at first occur is CSD, it is the abbreviation of circuit switched data services, and what voice communication was at present adopted also is the CSD technology, in this case, voice call and other data transmit, can not carry out simultaneously, CSD takes Circuit-switched mode, and the WAP business of handset dialing is exactly Circuit-switched mode, its transfer rate only is 9.6kbps, therefore only is fit to a spot of, slow data transmission service.
HSCSD (High Speed Circuit Switched Data) has appearred subsequently, i.e. high speed circuit switched data service.HSCSD belongs to a kind of technology of 2.5G, be the upgraded version of GSM network, can transmit simultaneously through the multiple time-division, rather than have only the single time-division, therefore transmission speed significantly can be risen to usual two to three times, its transmission speed can reach 57.6kbps.
Now most popular is GPRS GPRS (General Packet RadioService), and it is a kind of wireless, packet-switched technology based on gsm system, provides end to end, wireless IP connects.Briefly, GPRS is the technology that a high-speed data is handled, and its method is the form transmission data with " grouping ".Network capacity is only distributed when required, does not just discharge in the time of, and this send mode is called statistic multiplexing.At present, the transmission speed of GPRS mobile radio communication can reach 115kbps.GPRS is the technology that grows up on the GSM basis, is a kind of technology between second generation digital communication and third generation packet-type mobile service, so be commonly referred to 2.5G.
As mentioned above, the speed of mobile radio network is all very slow, and the stability of transmission is also very poor, when user's download during greater than the large resource of 1MB, often needs several minutes, if when downloaded files is bigger, download time well imagines.In case network failure in downloading process, occurs, the part of having downloaded will all disappear, Internet resources have been wasted greatly, more having wasted user's download time and mail downloading charge uses, simultaneously also be difficult to allow user interim time-out in needs be downloaded, make the user almost be difficult to realize at mobile phone to download large resource.
Although in order to solve on the mobile device downloaded resources problem slowly, mobile radio network has more at a high speed appearred, perform to EGPRS (EDGE) enhanced data rate for global evolution and the 3G network of the limit as function with GPRS, the speed of wireless downloading can reach 384Kbps to 2Mbps, but the problem that exists breakpoint to download equally.And because new mobile radio network limited coverage area and high usage charges, short-term can't extensively be adopted by masses, above-mentioned low-speed wireless mobile network also will be widely used in the quite a long time, and how solving the problem of downloading large resource is to be badly in need of solving.
Publication number provides a kind of wireless downloading method of non-JAVA content for the Chinese patent application of CN15922981, and may further comprise the steps: (1) downloads MFD by a portable terminal from the OTA server; (2) described portable terminal is judged MFD according to its mime type, and decomposes MFD and be used for content and download and report to URL; (3) described portable terminal is downloaded to described server requests content, and downloaded contents is downloaded on the described portable terminal, and is stored; (4) described portable terminal is to described server report content download state, and described server responds this; (5) described portable terminal is downloaded successfully to user's displaying contents.But it is unresolved how in the problem that realizes breakpoint transmission download large resource on mobile phone.
Summary of the invention
