The logic level of the sampling pin of device 750 is overturn, i.e., is changed into low level from high level.The central processing unit 750 can root
Interrupt signal is produced according to the logic level change, and then, operated by the generation of the interrupt signal Trig control signal, export the control
The control terminal that signal processed switchs to switching.
Optionally, four built-in aerials are preset in the mobile terminal, at least built-in aerial and corresponding radio frequency
Connected between receiving circuit the antenna switching circuit.
When external antenna device does not access external antenna connector, i.e., the one kind provided such as Fig. 8 a does not access external antenna
Mobile terminal structural representation shown in.The detection pin of external antenna connector 810 is vacant state, and output high level is extremely
Central processing unit 850.So as to the control signal that output control antenna does not switch of central processing unit 850 to antenna switching circuit
820.The first end for switching switch in the antenna switching circuit 820 is connected with the second end, with connect RF receiving circuit 830 with it is interior
Put antenna 860.The radiofrequency signal received by RF receiving circuit 830 to built-in aerial 860 is filtered, net mate etc.
After reason, export to radiofrequency signal processor 840.The radiofrequency signal after processing is demodulated by radiofrequency signal processor 840
Processing, and the radiofrequency signal after demodulation process is exported to the central processing unit 850.
When external antenna device accesses external antenna connector, i.e. the shifting such as a kind of Fig. 8 b access external antennas provided
Shown in the structural representation of dynamic terminal.Because the state output end of the external antenna device 870 docked with the detection pin is low
Level, external antenna connector 810 detection pin connection external antenna after, the level of the detection pin is pulled low, output it is low
Level is to central processing unit 850.Central processing unit 850 produces interrupt signal, and then, generation control letter is triggered by the interrupt signal
Number, the control signal is exported to the control terminal for switching switch.Control switching switch connection first end and the 3rd end, and disconnect first
The connection at end and the second end, realizes part built-in aerial 860 switching to external antenna.In part, the connection of built-in aerial 860 is penetrated
While frequency receiving circuit 830, external antenna device 870 also connects RF receiving circuit 830 by switching switch.Pass through radio frequency
It is defeated after the processing such as the radiofrequency signal that receiving circuit 830 receives to built-in aerial 860 and external antenna is filtered, net mate
Go out to radiofrequency signal processor 840.Processing is demodulated to the radiofrequency signal after processing by radiofrequency signal processor 840, and
Radiofrequency signal after demodulation process is exported to the central processing unit 850.
The embodiment of the present invention provides a kind of compatible built-in and external antenna mobile terminal, outer in external antenna device access
After putting antenna connector, the radio frequency being connected with built-in aerial of quantity will be set by central processing unit control antenna switching circuit
Receiving circuit switches to connection external antenna device, realizes after external antenna device access, replaced using external antenna built in
Antenna is communicated, and makes full use of MIMO, multiband carrier aggregation capacity of base station etc., can be lifted to greatest extent mobile whole
The data downloading speed at end, solve the problems, such as, because the MIMO function limitations of built-in aerial influence downloading rate, to have reached and improved
Antenna performance, so as to improve the effect of the handling capacity of data under MIMO mode agreement.
Pay attention to, above are only presently preferred embodiments of the present invention and institute's application technology principle.It will be appreciated by those skilled in the art that
The invention is not restricted to specific embodiment described here, can carry out for a person skilled in the art various obvious changes,
Readjust and substitute without departing from protection scope of the present invention.Therefore, although being carried out by above example to the present invention
It is described in further detail, but the present invention is not limited only to above example, without departing from the inventive concept, also
Other more equivalent embodiments can be included, and the scope of the present invention is determined by scope of the appended claims.
