Embodiment
The invention discloses a kind of mobile terminal call based on AT instruction and switch field survey method and system, for making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is the flow chart of the preferred embodiment of the mobile terminal call switching field survey method that the present invention is based on AT instruction.The mobile terminal call based on AT instruction shown in Fig. 1 switches field survey method, comprising:
Step S101, transmit AT instruction by serial line interface to the mobile terminal that is attached thereto, make described mobile terminal start corresponding call operation according to the AT instruction received.
In the embodiment of the present invention, adopt AT instruction to control mobile terminal and start call operation.AT instruction provides the hardware interface-serial ports of one group of standard.Due to the simplification of hardware designs, newer communication network module nearly all adopts serial ports hardware interface.Therefore, as long as the mobile terminal in the present embodiment is connected the transfer operation can carrying out AT instruction with PC computer with USB line.
Step S102, within the booked call time, in real time monitoring mobile terminal switches to the call state of second area from first area, if detect, described call state changes, then judge that the call state of described mobile terminal is as dropped call.
In the embodiment of the present invention, need to preset a call control information, described call control information comprises: call time and duration of a call time.Preferably, the present invention sets call control information and is: call out 60 minutes, duration of a call 30 seconds.Further, described step S102 specifically comprises step:
S21, control mobile terminal by AT instruction and start corresponding call operation, and the call state of real-time monitoring mobile terminal;
If S22 detects that mobile terminal cannot be connected within the described 30 seconds duration of a call time, then judge that the call state of described mobile terminal is as call failure, and after the described 30 seconds duration of a call time, again control mobile terminal by AT instruction and start corresponding call operation, and return execution step S21;
If S23 detects that mobile terminal is connected within the described 30 seconds duration of a call time, then judge that the call state of described mobile terminal is as access success, and whether the call state that real-time monitoring mobile terminal switches to second area from first area within 60 minutes call times of presetting changes;
If S24 detects that the call state of mobile terminal changes, then judge that the call state of described mobile terminal is as dropped call, and after the described 30 seconds duration of a call time, again control mobile terminal by AT instruction and start corresponding call operation, and return execution step S21;
If S25 detects that the call state of mobile terminal does not change, then control mobile terminal and to stop call operation.
That is, after controlling mobile terminal startup call operation by AT instruction, detect mobile terminal and whether connected phone in 30 seconds that preset, if access failure (i.e. call failure), then interval starts call operation after 30 seconds again, and repeats above operation; If connect, then detect mobile terminal in 60 minutes of calling further and switch to from first area the situation (as: dropped call) whether second area exists call state generation abnormal change, if dropped call, then interval starts call operation after 30 seconds again, and repeats above operation; If non-dropped call, then terminate this time calling field and survey.
Step S103, obtain the relevant abnormalities information of the mobile terminal of dropped call of being in, and described relevant abnormalities information is outputted in default Excel form automatically, to realize switching to mobile terminal call the automation record surveyed field.
In the embodiment of the present invention, described relevant abnormalities information comprises: the time point extremely occurred, call signal quality and intensity and anomalous event type, described anomalous event type comprises: dropped call and call failure.Further, described step S103 specifically comprises step:
S31, detect that mobile terminal is in dropped call or call failure state, then obtain real-time system time and call signal quality and intensity by AT instruction, and is set as the described abnormal time point occurred the real-time system time of acquisition;
