In the portable terminal of realizing the long distance radio communication by GSM the WLAN communication link to be set is example.In portable terminal, be provided with after the WLAN communication link by single CPU scheme, use this portable terminal to communicate by letter if desired, then need at first to start portable terminal, also need initialization WLAN communication link with WLAN, start ICP/IP protocol, insert WLAN by the WLAN communication link afterwards.Like this, portable terminal if this message is GSM message, then enters corresponding interface when receiving process message; If this message is the WLAN related news, then handle this message by the WLAN communication link.
For two CPU schemes, referring to Fig. 3, need on long distance CPU, connect a low coverage CPU who is used to handle low coverage WLAN communication, and realize and being connected of WLAN communication link that with the low coverage CPU of this new interpolation low coverage CPU is identical with the connected mode in single CPU scheme with the connection of WLAN communication link.Original CPU still realizes original mobile terminal function, and portable terminal was realized by low coverage CPU with being connected then of WLAN.Because two-port RAM has two sets of data lines and address wire, can support two CPU to carry out reading and writing data, can finish two exchanges data between the CPU by two-port RAM, therefore, exchanges data between long distance CPU and the low coverage CPU can realize by two-port RAM, accordingly, also need to add the driving of corresponding two-port RAM.
Be example in the portable terminal of realizing the long distance radio communication by GSM, the WLAN communication link to be set equally.In portable terminal, be provided with after the WLAN communication link by two CPU schemes, use this portable terminal to communicate by letter if desired with WLAN, then need at first to start portable terminal, after starting portable terminal and inserting the GSM network, also need initialization two-port RAM and WLAN communication link, start ICP/IP protocol, insert WLAN by the WLAN communication link more afterwards.Wherein, the initialization of WLAN communication link is realized by low coverage CPU.
By such setting, portable terminal is judged the current WLAN communication link that whether needs to operate when the operation gsm system, and if desired, then gsm system is placed on instruction and data in the two-port RAM; Low coverage CPU is the data in the poll two-port RAM then, if having the data of usefulness, then obtain these data, and these data are sent by the WLAN communication link.When the low coverage CPU WLAN (wireless local area network) data that reception comes to the WLAN communication link are handled,, then data are sent to two-port RAM if these data need send to original CPU; Original CPU then obtains wherein data by the poll two-port RAM, and these data are handled.
Above-mentioned to be two CPU obtain the process of data by the poll two-port RAM, and in fact, two CPU can also obtain data in the two-port RAM by interrupt mode.Specifically, gsm system adopts the mode of interrupting to notify low coverage CPU after being put into instruction and data in the two-port RAM, and low coverage CPU then after receiving the notice that original CPU sends, obtains the data in the two-port RAM; Low coverage CPU also adopts interrupt mode to notify original CPU to obtain data after sending to data in the two-port RAM, and carries out relevant operation.
Though can in portable terminal, realize two by above-mentioned two kinds of schemes apart from radio communication, but, because the realization more complicated of WLAN (wireless local area network), on hardware, need to comprise circuit such as MAC, BBP, rf modulations demodulation, power amplification, if these hardware circuits are directly joined portable terminal, then will increase the volume of portable terminal greatly.Be to solve the volume problem, MAC module, BBP module and rf modulations demodulation module that can choice structure very little single-chip or single module are realized WLAN are integrated in the chip, certainly, and also can be with in the module of whole WLAN communication link basis to.Like this, just can solve the volume problem when in portable terminal, WLAN being set effectively.
In addition, because the power consumption of WLAN even under sleep state, also has 200mW all than higher, this can shorten the stand-by time of portable terminal greatly.And the user wishes that the stand-by time of portable terminal can be long as best one can.For solving power problems, can do following the setting for the WLAN in the portable terminal:
1, because the power consumption of WLAN under resting state is very low, approximately have only 300uW up, and the portable terminal under resting state can be waken by the long distance wireless network, therefore, can be set to resting state by WLAN, portable terminal wakes WLAN again up when needs carry out data interaction by WLAN.
2, because WLAN can be timed and wakes up, and sending beacon and listen for beacons under sleep state, therefore, is to reduce power consumption, and the WLAN in can portable terminal is set to sleep state.The common timing wake-up time of WLAN is 100ms, be to reduce power consumption, improves the stand-by time of portable terminal, can be with the timing wake-up time lengthening, such as, the timing wake-up time is set to 300ms.Certainly, can also according to self needs be set the timing wake-up time neatly by the user, so that the WLAN communication link is in flexible sleep state.
3, be the low coverage radio communication on the portable terminal because WLAN is applied in, therefore, can lower power output be set, to reduce the power consumption of WLAN under emission state for WLAN.Such as, the power output of WLAN is set to 10dbmW～13dbmW.
Certainly, can use WLAN function in the portable terminal better, multiple different sleep state can also be set for the WLAN communication link in the portable terminal, and select voluntarily as required by the user for making the user.Such as, the sleep state of WLAN communication link is set to comprise: complete sleep state, flexible resting state and normal hibernation state.
If the WLAN communication link is in complete sleep state, then the WLAN function just has been closed fully, and portable terminal at this moment is identical with the function of common mobile terminal.In this case, start the WLAN communication link if desired, then need to wake up by portable terminal.
If the WLAN communication link is in flexible resting state, then the user can be by the wakeup time of change WLAN, to adjust the time interval that WLAN sends listen for beacons, to adapt to needs of different applications: if move ageing stronger, then can shorten wakeup time, that is to say, exchange the smooth effect of application with bigger power consumption for; If operation is ageing not strong, then can prolong wakeup time, to reduce power consumption.
If the WLAN communication link is in the normal hibernation state, then the WLAN wakeup time of portable terminal using system acquiescence like this, can not miss under the situation of monitoring signal in assurance, reduces the power consumption of WLAN as much as possible.
Also having a problem is signal interference problem.Though long range communication is different with the frequency range at Near Field Communication place, the modulation demodulation system of employing is also different, but still has crosstalking and problem such as interference between two kinds of communications.What wherein, have the greatest impact is exactly the sensitivity of received signal.The sensitivity of GSM/GPRS or CDMA is-105dBmw that the sensitivity of WLAN (wireless local area network) is-86dBmw that the intensity of these two kinds of radio communication received signals is all very low.The signal that GSM/GPRS or CDMA send is exactly to disturb for WLAN, and is same, and the signal that WLAN sends also is to disturb for GSM/GPRS or CDMA.
For solving signal interference problem, can be when layout and circuit cabling be set, GSM/GPRS or cdma system are arranged in the one side of wiring board, WLAN is arranged in the another side of wiring board, and the radio frequency part on two sides is all used and is inhaled wave apparatus and the screening arrangement such as mask frame, screening cover, to avoid mutual interference, the concrete plan of establishment can be referring to Fig. 4 and Fig. 5.Among Fig. 4, separate at the rf modulations of GSM/GPRS or CDMA be in harmonious proportion power amplification and radio-frequency (RF) switch arranged outside GSM mask frame and inhale wave apparatus.Among Fig. 5, also be provided with the WLAN mask frame in the outside of separating mediation power amplification and radio-frequency (RF) switch at the rf modulations of WLAN and inhale wave apparatus.
Can also improve the central layer thickness on the wiring board, to improve the isolation of these two systems.When the antenna of these two systems is set, can also adopt two kinds of measures of spatial separation and polarization isolation to avoid interference between antennas.Specifically, spatial separation is: keep the invariant position of portable terminal long range communication antenna, the position of WLAN antenna is arranged on the distal-most end of portable terminal middle distance long range communication antenna.Polarization isolation is: these two antennas are set to the orthogonal polarizations mode, with improve two between the antenna isolation, reduce the phase mutual interference between two antennas.The schematic diagram of Fig. 6 for antenna is carried out polarization setting.
By above-mentioned setting, can realize the low coverage radio communication of portable terminal.Can also on the basis of this portable terminal, further add IGRS agreement and application corresponding, so just can realize and the interconnecting of other equipment, resource-sharing and cooperation with service by the IGRS agreement.For the portable terminal of realizing the low coverage radio communication by single CPU, the operation application relevant if desired with IGRS, then the CPU of portable terminal directly handles related data.For the portable terminal of realizing the low coverage radio communication by two CPU, the operation application relevant if desired with IGRS, then the original CPU of portable terminal is placed on data in the two-port RAM; Low coverage CPU is the data in the poll two-port RAM then, if find to have among this RAM the data of usefulness, then carry out relevant operation, and the data after will handling return to original CPU by two-port RAM, and original CPU then obtains data by the poll two-port RAM.Certainly, these two CPU also can adopt interrupt mode to obtain data in the two-port RAM: after the original CPU of portable terminal is placed on data in the two-port RAM, by interrupt mode notice low coverage CPU, low coverage CPU obtains the data in the two-port RAM, and carry out relevant operation, and adopt the data after interrupt mode will be handled to return to original CPU equally by two-port RAM.
The above only is the present invention program's preferred embodiment, not in order to limit protection scope of the present invention.
