Fig. 2 is based on an embodiment flow chart of awakening method between a kind of mobile terminal module of the present invention embodiment illustrated in fig. 1.
Embodiment
At first, briefly set forth principle of the present invention.Among the present invention, between the module that two needs wake up mutually, be provided with two holding wires, and adopt the mode of hardware interrupts, realize interrupting waking up state-detection with the other side by described two holding wires.
The present invention will be described in detail below in conjunction with accompanying drawing.
With reference to figure 1, illustrate the structural representation of an a kind of embodiment of multimode terminal among the present invention.As shown in the figure, described multimode terminal comprises gsm module 10 and CDMA module 20, and described gsm module 10 and CDMA module 20 are all as independent communication module.
Be connected with universal serial bus UART between described gsm module 10 and the CDMA module 20, and the GPIO3 of described gsm module 10 is connected with the GPIO13 of described CDMA module 20 as the power supply port; The reset signal of described gsm module 10 is sent to the GPIO14 of described CDMA module 20 by its GPIO4.
And, also be connected with two other holding wire G2C and C2G between described gsm module 10 and the CDMA module 20.The end of described holding wire G2C connects the GPIO1 of described gsm module 10, and the other end connects the GPIO11 of described CDMA module 20; The end of described holding wire C2G connects the GPIO2 of described gsm module 10, and the other end connects the GPIO12 of described CDMA module 20.
Wherein, the GPIO11 of described CDMA module 20 is set to the I/O mouth that interrupts importing, and the GPIO2 of described gsm module 10 is the I/O mouth for being set to interrupt importing also.
Described holding wire G2C initiates interrupt requests to carry out the holding wire of wake operation as gsm module 10 to CDMA module 20, also detects the holding wire of the state of gsm module 10 simultaneously as CDMA module 20.
Equally, described holding wire C2G initiates interrupt requests to carry out the holding wire of wake operation as CDMA module 20 to gsm module 10, also detects the holding wire of the state of CDMA module 20 simultaneously as gsm module 10.
Mutual wakeup process for described two intermodules reaches, and the process of state-detection can be with reference to elaboration hereinafter.
With reference to figure 2, illustrate an embodiment flow chart based on awakening method between a kind of mobile terminal module of the present invention embodiment illustrated in fig. 1.In the present embodiment, with 20 pairs of described gsm modules 10 of described CDMA module the handling process of the GSM end of wake request being arranged is that example is set forth.
As shown in the figure, may further comprise the steps:
Step S21, the CDMA module sends interrupt request singal.
That is, the C2G holding wire of CDMA module by being connected with its GPIO12 sends interrupt request singal to the GPIO2 of described gsm module.
Interrupt request singal herein must be the interrupt request singal that described gsm module is accepted, for example if gsm module GPIO2 is set to the words of level interrupt response, then the CDMA module must send a level interrupt request singal by its GPIO12, and if gsm module GPIO2 is set to pulse edge and triggers interrupt response, then the CDMA module must send a pulse-break request signal by its GPIO12.
Wherein, the interrupt request singal of the interrupt response signal of described gsm module and described CDMA module be defined as in last once Interrupt Process process, determine.Concrete, an one embodiment also can be with reference to elaboration hereinafter.
Step S22, gsm module receives interrupt request singal.
That is, gsm module receives interrupt request singal from holding wire C2G by its GPIO2.
Step S23 judges the state of C2G holding wire, if low level, if execution in step S27 then is high level, then execution in step S24.
Wherein, this deterministic process is finished by gsm module, and this process is promptly as the process of state-detection.
In the present embodiment, when gsm module detects described holding wire C2G upward for high level, think that then the CDMA module is in running order, if low level thinks that then the CDMA module is in resting state;
In like manner, when the CDMA module detects described holding wire G2C upward for high level, think that then gsm module is in running order, if low level thinks that then gsm module is in resting state.
Step S24, the in running order and record of CDMA module.
That is, when gsm module judges that the C2G holding wire is high level, think that then the CDMA module is in running order, this moment, gsm module was noted the last state of CDMA module.
Step S25, it is the response mode that operating state and setting respond interrupt requests next time that gsm module is set.
Promptly, when the CDMA module sends interrupt request singal to gsm module by the C2G signal, and gsm module to detect the C2G holding wire be high level, show that the CDMA module is an operating state, just illustrate that the CDMA module has this moment need to wake the request that gsm module sends data up.Thereby, when being resting state, then be provided with certainly as operating state so that receive data as if the gsm module current state.
And for the ease of corresponding interrupt requests from the CDMA module next time, gsm module will be provided with the mode that next time responds interrupt requests this moment.
For present embodiment, because this moment, the C2G holding wire was a high level, two modules are all in running order at present, thereby the CDMA module sends interrupt request singal once more and should be low level (also may be prescribed as pulse edge trigger), so the mode that responds interrupt requests of gsm module is set to the mode of low level response next time.
Step S26 wakes gsm module up.
That is, in order to receive data, after oneself state is set is operating state, just wake gsm module up from the CDMA module.
Wherein, need to prove, the described gsm module self working state that is provided with is by the level of G2C holding wire being put height or putting to hang down and realize, if put height, then show gsm module in running order (detecting) for the CDMA module, low as if putting, show that then gsm module is in resting state (detecting for the CDMA module).
After this step finishes, execution in step S29.
Step S27, the CDMA module is resting state and record.
That is, when the holding wire that detects C2G as step S23 is low level, show that then the CDMA module is in resting state at this moment, then need to write down the last state of current C dma module in this step.
Step S28 is provided with the mode that next time responds interrupt requests.
That is, gsm module finishes after described CDMA module sends interrupt requests in response, in order to respond the interrupt requests that CDMA module is next time sent, the response mode of interrupt requests next time need be set.
In the present embodiment, because current CDMA module is in resting state, be low level on the described C2G holding wire, thereby the mode of interrupt requests should be high level triggering (artificial regulation next time, can certainly all be defined as the triggering of pulse edge), thereby the interrupt response mode of described its GPIO2 of gsm module is set to the high level response at this moment.
Step S29 finishes.
Among another embodiment of awakening method, suppose that two modules all are in resting state between a kind of mobile terminal module of the present invention, this moment, one of them module need be waken another up.Waking the CDMA module up with gsm module is example (CDMA module wake gsm module up process similarly):
When gsm module detects the C2G holding wire and is low level (showing that the CDMA module is in resting state), because this moment, the G2C holding wire also was low level (all being in resting state), thereby gsm module only need be put the level of G2C holding wire high getting final product at this moment, so, the GPIO11 of CDMA module only need be set to that rising edge trigger to interrupt or high level triggers and interrupts getting final product.
Need to prove, below only set forth the CDMA module and waken the process of gsm module up, because the process that gsm module wakes the CDMA module up similarly, art technology people only can obtain the process that gsm module wakes the CDMA module up with above-mentioned elaboration, thereby does not set forth at this.
In addition, described two modules are not limited to gsm module and CDMA module, it can be the combination in any between gsm module, CDMA module, TD-SCDMA module, the WCDMA module, because the inside of these communication modules is formed all very ripe, also be that those skilled in the art can obtain easily, thereby it further do not set forth.
In the above-described embodiments, the interrupt response mode of only having set forth the side of being waken up is the mode of level response, and it can also be that pulse edge triggers interrupt response, because process is similar, does not describe at this.
In above-mentioned embodiment, high level is represented in running orderly on two holding wires of regulation C2G and G2C, and low level represents to be in resting state, and it can also be conversely, and promptly low level is represented in running orderly, and high level represents to be in resting state.
Among the present invention, promptly realized interrupting waking up and state-detection, promptly provided cost savings, increased reliability simultaneously again by two holding wires.
Above disclosed only is preferred embodiment of the present invention, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of doing according to claim of the present invention still belongs to the scope that the present invention is contained.
