Needs for adaptation work and life, the user is more and more stronger to the demand of dual-network and dual-standby terminating machine, require existing terminating machine need possess the function of double-card dual-standby, that is to say, on a terminating machine, can dispose two subscriber identification module (SIM simultaneously, Subscriber identification Module) card, promptly on a mobile phone, dispose two wireless communication modules, two protocol stacks, drive corresponding wireless communication module by the radio interface layer driver module, and carry out the related communication operation as required.
Because aforesaid operations system platform and software architecture thereof are not supported the mechanism of two protocol stacks, two wireless communication modules and two card standbies simultaneously, in order to realize the double-card dual-standby function based on the aforesaid operations system platform, prior art has proposed a kind of expansion RIL agency (PROXY) device based on Windows Mobile platform and has driven two wireless communication modules with realization by radio interface layer.
Fig. 1 is existing expansion RIL agent apparatus structural representation based on Windows Mobile platform.Referring to Fig. 1, this device comprises: the upper application module of customization, Microsoft's upper application module, expansion RIL proxy module, RIL proxy module, RIL driver module, first communication module and second communication module, wherein,
The upper application module of customization, be used to store the upper layer application of multi-mode terminating machine expansion, invoke extensions RIL proxy module, RIL driver module and second communication module, registration is also obtained expansion RIL handle, according to the instruction triggers upper layer application of user's input, call corresponding expansion RIL proxy function according to the expansion RIL handle that obtains;
Wherein, for instance, if original Windows Mobile operating system is only supported the gsm protocol stack, then Ding Zhi upper application module is used to store the relevant upper level applications of CDMA protocol stack, for example, telephony application (TAP, Telephony Application Program), short message service (SMS, Short Message Service) program, SIM card stored program etc., correspondingly, the instruction of user's input comprises the dialing instruction, service order or the instruction of storage SIM card etc. send SMS message.
In the practical application, if the user selects to dial by the gsm protocol stack, then Ding Zhi upper application module is called RIL agency dialing function.
Microsoft's upper application module, be used to store the upper layer application of multi-mode terminating machine Microsoft acquiescence, call RIL proxy module, RIL driver module and first communication module, registration is also obtained the RIL handle, according to the instruction triggers upper layer application of user's input, call corresponding RIL proxy function according to the RIL handle that obtains;
The RIL proxy module, be used to be stored as the dynamic link library (DLL that Windows Mobile carries, Dynamic Link Library), according to the RIL proxy function of calling in the dynamic link library, the DeviceIOControl that will be converted to the RIL driver module the user instruction of Microsoft's upper application module input calls;
Expansion RIL proxy module is used to store the dynamic link library of expansion, and according to the expansion RIL proxy interface function that calls, the DeviceIOControl that will be converted to the RIL driver module the user instruction that the upper application module of customization is imported calls;
In the practical application, the dynamic link library of expansion can be rewritten with reference to the upper layer application of original dynamic link library of Windows Mobile and expansion, and this can be obtained by those of ordinary skills' design, does not repeat them here.
Wherein, can in DeviceIOControl calls, comprise the RIL handle, with sign to calling that the user instruction of the upper application module input of customization is changed.
The RIL driver module is used for calling the handle that comprises according to DeviceIOControl, to first communication module or second communication module transmit operation designated command;
As previously mentioned, if first communication module is the gsm communication module, the RIL handle that comprises in calling according to DeviceIOControl of RIL driver module then is to first communication module transmit operation designated command.
First communication module is used for operating accordingly according to the operational order command execution of RIL driver module output;
If the operational order order is dialing order, i.e. AT order, then the called number that carries in the AT order of first communication module makes a call, and does not repeat them here.
Second communication module is used for operating accordingly according to the operational order command execution of RIL driver module output.
By as seen above-mentioned, the existing method that realizes RIL driving multi-mode terminating machine based on Windows Mobile platform extension RIL agent apparatus, by on the basis of the RIL of original Microsoft proxy module, increasing expansion RIL proxy module, and corresponding change RIL driver module, be used for the upper layer application of customization is handled, thereby the RIL that realizes multi-mode terminating machine drives.But because a RIL driver module needs corresponding a plurality of proxy modules, be after the research staff finishes the dynamic link library of corresponding expansion according to multimode terminal user's demand exploitation, also need the dynamic link library of a plurality of expansions is merged, debugging is placed in the RIL driver module so that dynamic link library of compatible each expansion of energy, like this, RIL drives and realizes more complicated, RIL driver module and each proxy module coupling are big, make that proxy module design reusability is not high, merge, the dynamic link library of debug extensions is loaded down with trivial details, has increased the design cycle, reduced the stability of multi-mode terminating machine; Simultaneously, because the shared RIL driver module of a plurality of proxy modules, the communication efficiency of multi-mode terminating machine is limited by the RIL driver module, and communication efficiency is lower; And the RIL driver module need be safeguarded the state of a plurality of communication modules, has also increased the Design of device complexity.

In this step, calling corresponding RIL proxy function is RIL agency dialing function.
The program example that above-mentioned upper level applications is called RIL agency, registration RIL handle is as follows:
HRESULT?RIL_Initialize(
DWORD dwIndex, //RIL drives the numbering of n;
RILRESULTCALLBACK pfnResult, // upper level applications is registered to the call back function 1 of RILn;
RILNOTIFYCALLBACK pfnNotify, // upper level applications is registered to the call back function 2 of RILn;
DWORD dwNotificationClasses, // user's interest message mask;
DWORD dwParam, // upper level applications is sent to the parameter of RILn;
The RILn handle of HRIL*lphRil // be registered to returns to upper level applications oneself storage;
)。
After succeeding in registration, upper level applications is called by following routine call function:
HRESULT?RIL_Dial(
HRIL hRil, the RIL handle that // upper level applications obtains after registration;
LPCSTR lpszAddress, // the telephone number that transfer to;
DWORD dwType, // exhalation parameter;
DWORD dwOptions // exhalation option;
)。
In this step, call back function is corresponding with RIL agency dialing function.
In the above-mentioned example,, then transfer to successfully or the object information of failing passes to upper level applications by pfnResult, like this, realized dial-up operation from upper level applications to communication module if the user dials " 10000 " number.
Like this, drive by the RIL that designs a plurality of concurrent workings, not only simple in structure, and also system stability, upper level applications is exploitation easily also, and reproducibility is strong, is easy to realize the stand-alone development of many RIL drivings, and each RIL drives exploitation and does not disturb mutually.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
