[embodiment]
Below in conjunction with specific embodiment and accompanying drawing, technical scheme is described in detail.
As shown in Figure 1, in one embodiment, a kind of call answer method, comprises the following steps:
Step S10, sends alarm request.
In the present embodiment, user sends alarm request by mobile communication terminal to rescue centre or other mobile communication terminals.Such as, dialing mobile communication terminal number is 13511112311.In addition, GPS (Global Positioning System, GPS (Global Position System)) locating information can in alarm request, be comprised, for locating the geographical position residing for the mobile communication terminal sending alarm request.
Step S20, receives the response to alarm request, and sets up talking link.
Concrete, send alarm request for the first mobile communication terminal to the second mobile communication terminal to say, after second mobile communication terminal receives the alarm request of the first mobile communication terminal transmission, it is responded, after first mobile communication terminal receives this response, talking link is set up, to converse with the second mobile communication terminal.
Step S30, detects the signal whether receiving and trigger programmable button and produce, if so, then terminates, if not, return step S10.
Concrete, after talking link is set up, detect the second mobile communication terminal by DTMF (Dual Tone Multi Frequency, dual-tone multifrequency) and whether send the signal triggering programmable button and produce, namely after detection callee answers, whether press programmable button, and the first mobile communication terminal receives the corresponding signal of generation, if, then represent that this alarm request is effective, if not, then represent that this alarm request is invalid, need continue to send alarm request.Wherein, programmable button can be * button or # button etc., and other any buttons.
Further, in one embodiment, above-mentioned call answer method, also comprises step: sending short messages at definite time warning message, and this SMS alarm information comprises GPS locating information.Concrete, the interval transmitting time sending SMS alarm information can be set, as every 1 minute sends once.
Further, in one embodiment, above-mentioned call answer method, also comprises step: show the state, talking state and the transmission SMS alarm information state that send alarm request respectively.Concrete, when sending alarm request, display sends the state of alarm request; After talking link is set up, display talking state; When sending SMS alarm information, display sends SMS alarm information state.
As shown in Figure 2, in one embodiment, a kind of mobile communication terminal, comprises alarm unit 10, receiving element 20, detecting unit 30 and control unit 40.Wherein:
Alarm unit 10, for sending alarm request.
In the present embodiment, user sends alarm request by the alarm unit 10 of mobile communication terminal to rescue centre or other mobile communication terminals.Such as, dialing mobile communication terminal number is 13511112311.In addition, GPS (Global Positioning System, GPS (Global Position System)) locating information can in alarm request, be comprised, for locating the geographical position residing for the mobile communication terminal sending alarm request.
Receiving element 20, for receiving the response to alarm request, and sets up talking link.
Concrete, the receiving element 20 of mobile communication terminal receive that other mobile communication terminals or rescue centre send to after the response of alarm request, set up talking link with other mobile communication terminals or rescue centre, to converse.
Detecting unit 30, for detecting the signal whether receiving and trigger programmable button and produce.
Concrete, after talking link is set up, detecting unit 30 is by DTMF (Dual Tone Multi Frequency, dual-tone multifrequency) detect the signal whether mobile communication terminal receiving alarm request sends the generation of triggering programmable button, namely after detection callee answers, whether press programmable button, and the mobile communication terminal sending alarm request receives the corresponding signal of generation, if, then represent that this alarm request is effective, if not, then represent that this alarm request is invalid, need continue to send alarm request.Wherein, programmable button can be * button or # button etc., and other any buttons.
Control unit 40, during for detecting the signal receiving and trigger programmable button generation at detecting unit 30, control alarm unit 10 to stop sending alarm request, time also for detecting the signal not receiving and trigger programmable button generation at detecting unit 30, control alarm unit 10 and continue to send alarm request.
Further, in one embodiment, alarm unit 10 is also for sending short messages at definite time warning message, and SMS alarm information comprises GPS locating information.Concrete, the interval transmitting time sending SMS alarm information can be set, as every 1 minute sends once.
As shown in Figure 3, in one embodiment, above-mentioned mobile communication terminal, except comprising alarm unit 10, receiving element 20, detecting unit 30 and control unit 40, also comprises display unit 50.
Display unit 50, is controlled by control unit 40, for showing the state, talking state and the transmission SMS alarm information state that send alarm request respectively.
Concrete, when sending alarm request, display sends the state of alarm request; After talking link is set up, display talking state; When sending SMS alarm information, display sends SMS alarm information state.
Above-mentioned call answer method and mobile communication terminal, after setting up talking link according to alarm request and response, detect until receive the signal triggering programmable button and produce, just stop sending alarm request, can guarantee the validity that alarm request responds to improve success rate of seeking help.
In addition, according to GPS locating information, conveniently know the geographical position at the mobile communication terminal place sending alarm request, be convenient to realize relief; By timing SMS warning message, improve success rate of seeking help further; By showing various state, seeking help person is facilitated to go and find out what's going on.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
