Embodiment
In double card double standby mobile phone, there are two cover baseband chips, one of them be a master chip, another is from chip.The inventor finds in realizing process of the present invention: the operating system that these two chips adopt is the same, and the hardware of two chips and software are identical or only be that the structure of the message body of handling in two chips is variant slightly.Because the software and hardware of two chips is basic identical, therefore need not the common AT module that adopts in the existing multicore chip technology, need not to carry out message conversion by the AT module.Two baseband chips in the double card double standby mobile phone can not adopt the AT module and directly communicate.
Fig. 2 is a two-card two-standby mobile phone chip communication system example structure schematic diagram of the present invention, comprises chip 21 and from chip 22; Master chip 21 comprises UI module 211, first communication module 212; Comprise the second communication module 221 and second control module 222 from chip 22; 211 direct communications of UI module connect first communication module 212, and second communication module 221 direct communications connect second control module 222, and first communication module 212 direct communications connect second communication module 221.Therefore, can realize that by this paths of UI module → first communication module → second communication module → control module master chip is to the control from chip.
Wherein, can also comprise first control module 213 in the master chip 21, these first control module, 213 direct communications connect UI module 211, to realize the control of UI module to master chip.
Wherein, first communication module 212 and second communication module 221 can communicate to connect by serial ports or USB interface etc.
Present embodiment has been saved the exploitation of the AT module that adopts usually in the existing multicore chip technology according to the master chip of double card double standby mobile phone with from the characteristics of chip, can save cost, improves speed of production.
Fig. 3 is a two-card two-standby mobile phone chip communication means example structure schematic diagram of the present invention, comprising:
Step 31: when master chip need be controlled from chip, the UI module directly sent to first communication module with first message.
Wherein, first message is the message format that master chip is supported, has corresponding message body.
Step 32: first communication module obtains data message after to described first Message Processing, and described data message is sent to second communication module.
Wherein, if master chip and identical from the chip software and hardware, be that master chip is identical with the message body of supporting from chip, then first communication module only is to transmit this first message to give second communication module to the processing of first message, and promptly first message is identical with data message in this case.
Wherein, if master chip and the message body structure supported from chip are variant slightly, obtain described data message after then needing described first message to be handled by assembly unit and zero bit filling technique.Be specifically as follows: first communication module is ending with the end mark after the parameter in first message is converted to the message name that character string is assembled in first message; Obtain this data message after filling with zero bit filling technique then.
Wherein, first communication module can send to second communication module with this data message by serial ports or USB interface etc.
Step 33: second communication module obtains second message after described data message is handled, and described second message is directly sent to second control module.
Wherein, if master chip and identical from the chip software and hardware, be that master chip is identical with the message body of supporting from chip, then data message is first message, second communication module only is to transmit this data message (first message) to give second control module to the processing of data message, and promptly second message is identical with first message in this case.
Wherein, if master chip and variant slightly from the message body structure of chip support, because data message obtains after adopting assembly unit and zero bit to fill to first message, therefore second communication module obtains manageable second message of second control module after need be resolved this data message, be specifically as follows: the data message that second communication module scanning receives, the zero bit of filling is before removed, obtain second message after the parsing character string.
Wherein, if need to control master chip simultaneously, then the UI module can send command messages simultaneously to first control module in the master chip in the present embodiment.
Present embodiment need not to adopt the AT order to carry out message conversion when interchip communication according to the chip characteristics of double card double standby mobile phone, can simplify flow process.Simultaneously, can directly transmit message or employing assembly unit and zero bit filling technique according to concrete message body structure and handle, can be applied to concrete scene.
