Description
Technical field
The invention belongs to wireless communication technology field, automatically adapt to the method for different 3G data cards in a kind of Android system.
Background technology
The 3G data card is the widely used online medium of present cordless communication network.The 3G data card that function is comparatively perfect can be supported conversation, note and online three large major functions, relates in addition some other basic function and the inquiry of information.
Android is as an intelligent mobile phone platform, and its topmost function is the phone part.The function of phone part has comprised the functions such as conversation, note, data connection and SIM card, phone directory.Present most Android equipment has all comprised two processors on hardware structure: one is used for the operation system, runs some application programs, is referred to as application processor, is called for short AP (Application Processor); Another is responsible for the relevant work of Radio-Frequency Wireless Communication, is referred to as baseband processor, is called for short BP (Baseband Processor).Adopt serial ports to communicate between AP and the BP, what communication protocol was used is AT (Attention) instruction.Different vendor, the AT instruction of same manufacturer all can be used very large difference even.Therefore, Android carries out the communication between AP and the BP by a RIL (Radio Interface Layer), has realized public part wherein, the analysis unit of AT instruction is divided leave manufacturer's realization for.
The present main applied environment of Android system is some embedded devices, because the singularity of embedded device, and the realization of Android system framework, the Android system can not support different AT instructions simultaneously under normal conditions, the 3G data card that is to say different model is different for the realization of RIL part, therefore can not accomplish self-adaptation to the situation of external 3G data card.
The present invention is by built-in different 3G data card RIL dynamic link libraries and different configuration parameters on Android equipment, difference according to external 3G data card, guide different RIL dynamic link libraries, load corresponding configuration parameter, thereby solved above-mentioned problem.
Summary of the invention
Fundamental purpose of the present invention is to provide the method for 3G data card self-adapting under a kind of Android system, that is to say so that move the equipment of Android system can many moneys of automatic adaptation 3G data card.
For solving the problems of the technologies described above, technical scheme provided by the invention is: the method for 3G data card self-adapting under a kind of Android system, the method comprises the steps:
Preferably, in the step 101, judged whether external equipment by the USB Host port of monitoring external equipment, if external equipment is the equipment of supporting then enters step 102.
Preferably, in the step 102, judge that the method whether external equipment needs to carry out the pattern switching is, determine whether the CD pattern, if so, then execution in step 103; Otherwise, execution in step 104.
Preferably, in the step 104, external equipment obtains unique identifier, guides corresponding RIL dynamic link library according to unique identifier.
Preferably, in the step 105, after successfully guiding the RIL dynamic link library, pass through unique identifier, from configuration parameter, obtain the corresponding configuration parameter of RIL dynamic link library, in order to controlling procedure information and the AT order parameter in the RIL dynamic link library, thereby reach the purpose of adaptive different external connection peripheral hardware.
Preferably, judge that the method whether external equipment needs to carry out the pattern switching is, determine whether the CD pattern, if so, then execution in step 103; Otherwise external equipment obtains unique identifier, guides corresponding RIL dynamic link library according to unique identifier.
Beneficial effect of the present invention is: so that the 3G data card that can support external different model with a Android equipment reaches an adaptive function as communication module.
Description of drawings

Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
The method of 3G data card self-adapting comprises the steps: under a kind of Android provided by the invention system
In the step 101, judged whether external equipment by the USB Host port of monitoring external equipment, if external equipment is the equipment of supporting then enters step 102.
In the step 102, judge that the method whether external equipment needs to carry out the pattern switching is, determine whether the CD pattern, if so, then execution in step 103; Otherwise, execution in step 104.
In the step 104, external equipment obtains unique identifier, guides corresponding RIL dynamic link library according to unique identifier.
In the step 102, judge that the method whether external equipment needs to carry out the pattern switching is, determine whether the CD pattern, if so, then execution in step 103; Otherwise external equipment obtains unique identifier, guides corresponding RIL dynamic link library according to unique identifier.
The method of 3G data card self-adapting under a kind of Android system may further comprise the steps:
When 1) on detecting USB Host port, external equipment being arranged, judge what whether this peripheral hardware was supported.If this peripheral hardware be support enter next step operation.
2) judge for the peripheral hardware of supporting, if the outer CD pattern that is made as of this moment is then carried out the pattern switching until success; Then directly skip this step, the operation that directly enters next step if not the CD pattern.
3) from configuration parameter, obtain the RIL dynamic link library name of needs guiding according to the unique identifier of external equipment, and load.
4) configuration information in the loading configuration parameter offers the RIL dynamic link library and uses, and carries out the control of idiographic flow and the configuration of AT order parameter.
Fig. 1 is the major part of the whole flow process of the present invention, and as shown in Figure 1, main flow process of the present invention comprises following step:
101, the USB Host port of audiomonitor is until there is the peripheral hardware access.If external equipment is the equipment of supporting then enters next step.If the peripheral hardware that does not exist program to support on the USB Host port, then program can continue listening port.
102, judge whether peripheral hardware needs to carry out pattern and switch, and carries out the equipment that pattern is switched for needs, directly enters next step operation.Otherwise, will jump to subsequent operation.
103, the invocation pattern changeover program carries out the pattern switching.
104, for the pattern handover success or do not need to carry out the peripheral hardware that pattern is switched, obtain the unique identifier of equipment.Guide corresponding RIL dynamic link library according to unique identifier.
105, after successfully guiding the RIL dynamic link library, pass through unique identifier, from configuration parameter, obtain the corresponding configuration parameter of RIL dynamic link library, in order to controlling procedure information and the AT order parameter in the RIL dynamic link library, thereby reach the purpose of adaptive different peripheral.
Said method is so that the 3G data card that can support external different model with a Android equipment as communication module, reaches an adaptive function.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
