The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that, in order to just
Part related to the present invention rather than entire infrastructure are illustrate only in description, accompanying drawing.
It should be mentioned that some exemplary embodiments are described as before exemplary embodiment is discussed in greater detail
The processing described as flow chart or method.Although each step is described as the processing of order, many of which by flow chart
Step can be implemented concurrently, concomitantly or simultaneously.In addition, the order of each step can be rearranged.When its operation
The processing can be terminated during completion, it is also possible to the additional step being not included in accompanying drawing.The processing can be with
Corresponding to method, function, code, subroutine, subprogram etc..
Fig. 1 is a kind of structural representation of the mobile terminal with external antenna provided in an embodiment of the present invention, this implementation
The mobile terminal of example is applicable to user under non-WIFI environment, from the situation of base station downloading data, for example, user utilizes honeycomb
The scenes such as mobile network's viewing video.As shown in figure 1, the mobile terminal can include：
External antenna connector 110, for being accessed for external antenna device 160；
Detection circuit for access (is not drawn) in figure, is connected 110 mouthfuls and the electricity of central processing unit 120 with the external antenna respectively
Connection, for when the external antenna device 160 accesses mobile terminal, exporting and the non-access state of external antenna device 160
Different logic levels is to the central processing unit 120；
Central processing unit 120, the logic level for obtaining detection circuit for access output, judges according to the logic level
The connection status of the external antenna device 160, when having detected the access of external antenna device 160, performs mode of operation and cuts
Operation is changed, and the mode of operation after switching is reported into base station, so that the base station with the mode of operation after switching according to matching
Bandwidth of base station and communication of mobile terminal.
Wherein, external antenna connector 110 can be designed as the newly-increased interface on mobile terminal, and the newly-increased interface can be with
Inserted for external antenna device 160.For example, two external antenna connectors 110 can be reserved on mobile terminals, and will be external
Antenna connector 110 is designed as female form, so that the external antenna connector for being designed to male is accessed.
Optionally, the external antenna connector 110 can also be the multiplexing existing interface of mobile terminal, for example, earphone is inserted
Hole or USB interface.
Optionally, the external antenna connector 110 includes signal reception pin (not drawn in figure) and detection pin (not
Drawn in figure).The signal receives pin and electrically connected with RF receiving circuit 140, for being accessed in the external antenna device 160
During the external antenna connector 110, the signal output that the external antenna device 160 is received to the RF receiving circuit 140.
The detection pin is electrically connected with the detection circuit for access, for accessing the external day in the external antenna device 160
During line connector 110, pin logic level is overturn, and pin logic level after output switching activity to the access detects electricity
Road.
The detection circuit for access can be by the detection pin of external antenna connector be connected to central processing unit 120 certain
One default input and output pin is constituted.For example, when external antenna device 160 does not access external antenna connector 110, this is external
The detection pin of antenna connector 110 is in vacant state, exports high level.So as to make the central processing unit being connected electrically
The logic level of the 120 default input and output pin is high level.But, due to the external antenna docked with the detection pin
The input/output terminal (IO) of device 160 is low level, should when external antenna device 160 accesses the external antenna connector 110
Logic level at detection pin is dragged down by the external antenna device 160, and low level state is presented in the detection pin.So as to, with
The logic level of the default input and output pin of the central processing unit 120 of detection pin connection is overturn, i.e., by high electricity
It is flat to be changed into low level.The central processing unit 120 can preset the logic level change of input and output pin according to this, judge that this is outer
Put whether antenna assembly 160 accesses external antenna connector 110.
If central processing unit 120 has detected external antenna device 160 and accessed the external antenna connector 110, work is carried out
Operation mode switches.The central processing unit 120 realizes two antenna modes when the antenna operating mode for moving terminal is controlled

The instruction of output first controls the radiofrequency signal processor 130 to enable four antenna modes to radiofrequency signal processor 130, and to base
Station reports current mobile terminal to possess the communication capacity for receiving signal using four antenna transmission signals and four antennas.So as to,
Base station can be notified with the corresponding bandwidth of base station of 4 × 4MIMO and communication of mobile terminal.
Using 4 × 4MIMO compared to 2 × 2MIMO, available communication channel increase can increase transmitted per unit time
Data volume.Further, since external antenna is set outside mobile terminal, it can not be limited by the industrial design of mobile terminal, only
Dummy section can greatly improve antenna performance than larger, so that, further improve the downloading rate of mobile terminal.
And, when the external antenna device 160 does not access the external antenna connector 110, central processing unit 120 is defeated
Go out the second instruction to the radiofrequency signal processor 130, control the radiofrequency signal processor 130 to disable four antenna modes, enable two
Antenna mode, and report current mobile terminal to possess using two antenna transmission signals and two antennas reception signals to the base station
Communication capacity.It is thus possible to notify base station with the corresponding bandwidth of base station of 2 × 2MIMO and communication of mobile terminal.
The embodiment of the present invention by detected external antenna access external antenna connector when, switching working mode,
And the mode of operation after switching is reported into base station, base station is known the communication capacity that mobile terminal possesses so that, using with this
The bandwidth of base station of communication capacity matching issues data, and realization makes full use of MIMO, multiband carrier aggregation capacity of base station etc., can
To lift the data downloading speed of mobile terminal to greatest extent, solve because speed is downloaded in the MIMO function limitations influence of built-in aerial
The problem of rate, the effect of the handling capacity for the downloading data for improving mobile terminal is reached.
