Description
Technical field
The present invention relates to a kind of communication device and startup method thereof, the communication device and the startup method thereof of particularly a kind of energy integration of wireless access point and wireless network card function.Device of the present invention has one first storage module.This first storage module stores first driver and second driver corresponding to one second operator scheme corresponding to one first operator scheme.One user can pass through user's interface, optionally carries out this first operator scheme or this second operator scheme.
Background technology
The product of communications protocol IEEE802.11 series mainly can be divided into two classes, and a class is radio access point (Access point), and another kind of is wireless network card (Wireless adapter).This two series products is in the design of hardware, and the hardware circuit of its radio function is identical with chip.The main difference of two series products is the difference of its driver function.Load the driver of radio access point, this hardware can show the function of radio access point.Load the driver of wireless network card, this hardware can show the function of wireless network card.
In the IEEE802.11 communications protocol, the role of radio access point and wireless network card has significant different.If integrate the mode of both functions is to adopt both functions are integrated in the driver, allow the user can pass through graphic interface (GUI UTILITY) or hardware (BUTTON voluntarily, SWITCH) man-machine interface notifying operation system, remove the driver that (UNLOAD) moving, again be written into required driver again, because though the method is in the desktop operating systems such as WINXP/WIN2000 of Microsoft, and in the operating environment of LINUX support is arranged, but in some embedded OS, do not support, so this method can be restricted in the use.The method is in the practical operation of program and be not easy to reach thus.If integrate the mode of both functions is to adopt an operating system can load radio access point driver and WLAN Device Driver, and then the size of this operating system can be big than the operating system that can only load a kind of driver.This kind operating system also is not suitable for being used in the embedded system.If this operating system further comprises the function of unloading driver (Unload), the big young pathbreaker of this operating system becomes bigger, also is not suitable for putting into embedded system.
Therefore, a kind of method that can effectively integrate radio access point and WLAN Device Driver is provided, allow the user can on same device, use the function of radio access point or wireless network card, and the user select to use the merit able one of radio access point or wireless network card to truly have its necessity by user's interface.
Fig. 1, Fig. 2, Fig. 3 show the hardware configuration and the startup flow process of the embedded system of prior art.As Fig. 1, the hardware configuration of embedded system generally comprises CPU 1, FLASH (flash memory) 2, DRAM (dynamic RAM) 3 and peripheral device 4.The actuating code that wherein in FLASH 2, comprises two blocks at least, BOOT actuating code 5 and operating system actuating code 6 (driver that comprises peripheral device), as shown in Figure 2.Fig. 3 shows the startup flow process of embedded system.After the general CPU energising, the program reference position default by CPU begins to carry out BOOT actuating code 5 (step S300); Usually can set the parameter value of hardware in the BOOT actuating code module, check whether hardware capability is normal, the operating system actuating code is loaded among the DRAM, and the execution point of CPU jumped to the starting point (step S301) of operating system actuating code among the DRAM; The actuating code of operating system can be carried out necessary hardware and set, and is written into (load) and carries out the driver of peripheral device, and corresponding required process (process) (step S302).
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of communication device, and this communication device has been realized in embedded system fast and effeciently integration of wireless access point and wireless network card function and need not have been changed the driver of former simple function.
A purpose of the present invention is to provide the device of a kind of energy integration of wireless access point and wireless network card.This communication device comprises first driver and second driver corresponding to one second operator scheme corresponding to one first operator scheme.When one of this communication device started this first driver of (Booting) module loading, this device was promptly with this first operator scheme running.When this started this second driver of module loading, this device was promptly with this second operator scheme running.
Another object of the present invention is to provide a kind of user of allowing to pass through the device that user's interface selects to use radio access point or wireless network card function.This device has graphical user's interface or and switches circuit.The user can select to use radio access point or wireless network card function by this graphical user's interface or this commutation circuit.After this user selected this first operator scheme or this second operator scheme, this user's interface or this commutation circuit produced the selection signal of a response user operation.This selection signal is used to determine this first driver of this startup module loading or this second driver.
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
