Embodiment
Switch based on MEMS (Micro-Flectro-Mechanical Systems) technology is compared with the conventional switch device, has low-power consumption, low-loss, advantage such as highly integrated.The MEMS technology is with a wide range of applications in the switching field at a high speed at some.
The present invention utilizes the high speed diverter switch to carry out the switching of mobile phone card and radio-frequency front-end just, makes two cover cell phone systems be operated in different time slots, forms " taking turns " standby on the microcosmic.When the first cell phone system received signal, second cell phone system is in the radio listening silence state; When the second cell phone system received signal, first cell phone system is in the radio listening silence state again, avoids the phase mutual interference.The time location of expressing first cell phone system and the second mobile phone system works of Fig. 2 signal.When the first mobile phone clamping fashionable, the first mobile phone system works; When the second mobile phone clamping fashionable, the second mobile phone system works.Switch controlling signal produces by baseband processor.Baseband processor is according to the classification of the mobile phone card of user's use, and the conduction mode of automatic selector switch is realized the standbies simultaneously of the two cards of common mode, perhaps realizes different mode pair card standbies simultaneously.
Embodiment
As shown in Figure 3, the mobile communication terminal that this is routine, comprise first radio-frequency front-end, second radio-frequency front-end, first diverter switch, baseband processor, second diverter switch, the first mobile phone card, the second mobile phone card, and other functional units and power-supply system.In the first mobile phone card and the second mobile phone card, insert two respectively with first radio-frequency front-end and the corresponding mobile phone card of the second radio-frequency front-end mode of operation.Under the control of baseband processor, when first diverter switch is connected first radio-frequency front-end with baseband processor, when second diverter switch was connected the first mobile phone card with baseband processor, this routine mobile communication terminal can be finished the first mobile phone systemic-function; When first diverter switch is connected second radio-frequency front-end with baseband processor, when second diverter switch was connected the second mobile phone card with baseband processor, this routine mobile communication terminal can be finished the second mobile phone systemic-function.
In this example, baseband processor also needs first diverter switch and second diverter switch are controlled except the data processing and control task finishing the regular handset baseband processor and will finish.Finish the read-write to the mobile phone card after switch is stable, the sequencing control that this process need is very tight, this process can rely on software to realize.Consider power problems, switch control module is integrated on the baseband processor, and in view of the power of existing digital signal processing module (DSP, FPGA or MCU etc.), this processing method is to realize easily.
Behind this routine mobile communication terminal when startup, baseband processor is at first controlled second diverter switch and in two cycles the first mobile phone card and the second mobile phone card is connected with baseband processor respectively, and baseband processor is differentiated the mobile phone Card Type.After type was differentiated and finished, baseband processor was arranged on first diverter switch and second diverter switch under the operating state of mating with the mobile phone Card Type according to identification result.In order to adapt to different mobile phone cards, this example first mobile phone card and the second mobile phone card can compatible 2G mobile phone card and 3G mobile cards.Such as present GSM mobile handset card and W-CDMA mobile phone card.
It is the high speed diverter switch of RMSW221 that first diverter switch of this example and second diverter switch all adopt RADANTE MEMS company model.RMSW221 is based on the high speed diverter switch of MEMS technology, and the annexation of itself and baseband processor and mobile phone card (or radio-frequency front-end) as shown in Figure 4.The grid of RMSW221 (gate) is connected with the control signal of baseband processor output, and baseband processor is according to the communications time slot, and the mutual interference of two cover cell phone systems is avoided in the switching of control mobile phone card and radio-frequency front-end.
This routine mobile communication terminal has three kinds of mode of operations:
The first diverter switch short circuit of dual-card dual-standby pattern, first radio-frequency front-end is connected with baseband processor with second radio-frequency front-end simultaneously, by second diverter switch first mobile phone card and second mobile phone is sticked into the row switching, realizes the double-card dual-standby function.When first cell phone system in running order (talking state), second cell phone system is in holding state, utilizes the first mobile phone system communication time slot to send response message to the base station, and the call accepted request signal.When second cell phone system receives call request signal, discern by baseband processor, number priority order according to user's definition in mobile phone communication is thin, notify in real time whether the user is important phone, if as plain old telephone, and strange phone, then carry out record automatically, decide by the user and how to handle.The access situation of two mobile phone cards is seen Fig. 2.Under this pattern, first cell phone system can be operated in identical gsm communication network or cdma communication network (as: CDMA2000 or W-CDMA or TD-SCDMA) with second cell phone system.
The second diverter switch short circuit of double-module double-standby pattern, the first mobile phone card and the second mobile phone card insert baseband processor simultaneously, by the switching of first diverter switch to two cover radio-frequency front-ends, realize double-mode and double-standby function.When first cell phone system in running order (talking state), second cell phone system is in holding state, utilizes the first mobile phone system communication time slot to send response message to the base station, and the call accepted request signal.When second cell phone system receives call request signal, discern by baseband processor, number priority order according to user's definition in mobile phone communication is thin, notify the user in real time, whether be important phone, if as plain old telephone, and strange phone, then carry out record automatically, decide by the user and how to handle.Under this pattern, first cell phone system can be operated in the gsm communication network, and second cell phone system can be operated in cdma communication network (as: CDMA2000 or W-CDMA or TD-SCDMA).
The single deck tape-recorder standby mode descends when the power-supply system power supply capacity, and perhaps the user has specific demand, in the time of need closing wherein a cover system, carrying out mode of operation by the cell phone keyboard button switches, close wherein that a cover system enters the single deck tape-recorder standby mode, play energy-conservationly, economize the effect that takes.
