Comparing with prior art, the invention possesses features of simple technique, and being able to roam multiple networks seamlessly by using the wireless network card.
Description
Technical field
The present invention relates to the method for the control of automaticallying switch between a kind of network various modes, relate in particular to the control method that automaticallyes switch between the network various modes in a kind of wireless Internet card.
Background technology
Along with notebook computer day by day popularize and with people's inseparable internet, applications of living, mobile office, the demand of mobile Internet access is increase thereupon also, this demand has been complied with in the appearance of this new portable terminal product of wireless Internet card just.Present wireless Internet card mainly passes through two kinds of internetwork connection modes, CDMA, GPRS and the WCDMA that will go on the market, TD-SCDMA, CDMA2000 with being connected of mobile network.The control method that in these prior aries, does not relate to automatically switching network pattern in the dual-mode wireless card of surfing Internet, therefore how making gets online without being tethered to a cable is stuck in seamless roam in a plurality of networks, then be that problem to be solved is arranged in the prior art, be particularly related in a kind of TD-SCDMA/GPRS dual-mode wireless card of surfing Internet and automatically switch, the construction of TD-SCDMA network needs the time in several years, the dual-mode wireless online is very necessary and extensive market, comprised CDMA simultaneously, GPRS and the WCDMA that will go on the market, TD-SCDMA, two or two combination and multiple combinations of the 4G pattern in CDMA2000 and the research and development.
Summary of the invention
Purpose of the present invention is exactly to provide the control method that automaticallyes switch between the network various modes in a kind of wireless Internet card for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: the control method that automaticallyes switch between the network various modes in a kind of wireless Internet card is characterized in that this method comprises the following steps:
(1) wireless Internet card is in the GPRS connection status;
(2) whether detect the TD-SCDMA network strength greater than nominal threshold value, if testing result is then returned step (1) for not;
(3) if the result of detection is for being in the step (2), then synchronous with the maintenance of TD-SCDMA sub-district;
(4) connect with the TD-SCDMA sub-district;
(5) wireless Internet card is in the TD-SCDMA connection status;
(6) whether detect the TD-SCDMA network strength less than nominal threshold value, if testing result is then returned step (5) for not;
