Abstract
The short message sending process in vehicular terminal includes the following steps: the vehicular terminal to judge whether to exist blocking in the short message channel after receiving the sending request; the vehicular terminal to judge whether to need monitoring in case of blocking; if so, to send short message in alternate dual-tone multifrequency signal mode and phonetic signal mode; if not, to send short message in continuous dual-tone multifrequency signal; to send short message via the short message channel in case of no blocking; and to end sending. The present invention transmits DTMF signal via FACCH/F or FACCH/H with fast speed and can send the alarm signal and position information to the monitoring center timely. In addition, the DTMF signal has high decoding sensitivity, high decoding speed, strong anti-jamming capacity and high message sending reliability.
Description
(1) technical field
The present invention relates to the method that a kind of car-mounted terminal sends short message.
(2) background technology
At present, increasing vehicle begins to assemble vehicle mounted communication equipment, these equipment adopt GPS/GSM system (global positioning system/global system for mobile communications) usually, directly utilize alerting signal and the location information of the short message service of GSM by GSM network transmission vehicle.In the GSM network, generally be to transmit short message by low speed associated control channel SACCH when distribution services channel () or Separate Dedicated Control Channel SDCCH (during unallocated Traffic Channel).SACCH and SDCCH channel speed are very low, and must the certain signaling information of transmission.When taking place to report to the police, car-mounted terminal sends alerting signal and location information by these two kinds of channels, real-time a little less than, alarm message can not in time be responded probably, and when having a large amount of short messages to send request, the temporary obstruction that will cause channel, thus the alerting signal of making and location information can't in time transmit.
(3) summary of the invention
The object of the present invention is to provide a kind of car-mounted terminal to send the method for short message,, make monitoring and control centre can receive the message of car-mounted terminal comparatively timely by this method.
A kind of car-mounted terminal provided by the present invention sends the method for short message, after comprising the following steps: that car-mounted terminal is received the request of transmission short message, judge whether the note channel blocks: when the note channel takes place to block, this car-mounted terminal need further to judge whether to monitor: if, then adopt touch-tone signal and voice signal interval mode, send short message; If not, then adopt the mode that sends touch-tone signal continuously, send short message; When the note channel blocks, send short message by this note channel; Short message sends and finishes.
Adopt said method, utilize the Dual Tone Multifrequency signal by FACCH/F (Fast Associated Control Channel/at full speed) or FACCH/H (Fast Associated Control Channel/Half Speed) transmission, speed is fast, can comparatively timely alerting signal and location information be sent to monitoring and control centre, and decoding sensitivity, the decoding speed of dtmf signal are very high, antijamming capability is strong, sends the information reliability height.In addition, all within audio frequency range, when transmitting in voice-grade channel, decrement is very little for the frequency of dtmf signal, just need not transform transmitting DTMF signals easily to original voice-grade channel, and does not need any modification to final terminal, and cost is low.

(5) specific embodiment
As shown in Figure 1, the present invention, that is: a kind of car-mounted terminal sends the method for short message, after car-mounted terminal is received and is sent the short message request, judge whether the note channel blocks: when the note channel takes place to block, switch to the DTMF mode, car-mounted terminal need further to judge whether to monitor: if, then adopt touch-tone signal and voice signal interval mode, send short message; If not, then adopt the mode that sends touch-tone signal continuously, send short message to monitoring and control centre; When the note channel blocks, send short message by this note channel.Described short message comprises alerting signal and location information.
In above-mentioned process, principle and process that car-mounted terminal utilizes DTMF to send SMS message are as follows: after setting up speech path, car-mounted terminal sends request with DTMF and issues MSC with the form of message, and MSC sends corresponding D TMF signal according to content to monitoring and control centre after receiving message.Send a sound and need 4 signaling message: START_DTMF (beginning DTMF mode), START_DTMF_ACKNOWLEDGE (beginning DTMF mode is confirmed), STOP_DTMF (stopping the DTMF mode), STOP_DTMF_ACKNOWLEDGE (stopping the DTMF mode confirms).After having set up speech path, car-mounted terminal sends the START_DTMF request message to MSC, comprises the digital massage that needs send in this message, and MSC receives back transmission dtmf signal and beams back START_DTMF_ACKNOWLEDGE and confirm.Car-mounted terminal sends the STOP_DTMF request, stops to send dtmf signal after MSC receives and beams back STOP_DTMF_ACKNOWLEDGE and confirm.Each sound is repeated a said process.Second START_DTMF request can be sent before receiving first START_DTMF_ACKNOWLEDGE, can send dtmf signal continuously.
In the present invention, when taking place when reporting to the police, car-mounted terminal dials into the monitoring number of setting earlier, behind the other side's off-hook, sends the warning frame, parses corresponding field from the GPS frame, sends dtmf signal by top mode in the N under connecing minute.
In order to reduce the transmission quantity of information, increase the real-time of system, defined two kinds of frame formats of warning frame and position frame, as Fig. 2-shown in Figure 4.Wherein report to the police ID (sign), alarm source, check bit figure place is indefinite, and can omit this several sections according to actual conditions.
Monitoring and control centre receives the warning frame at the beginning earlier, the termination number in the intercepting frame, and the position frame acquiescence of next receiving all is to obtain from the car-mounted terminal of acquired termination number sign.For example car-mounted terminal 13916560228 will manually be reported to the police, and the GPS frame is:
GPSON，000020，V，3202.2645，N，11847.8685，E，32.123，0.0，290697，4.6，W
*7
Then its frame that successively sends is
*A13916560228
*(14)
*C118478685 32,022,645 32123
*(25)
Car-mounted terminal can once send when sending the warning frame if the interval of adopting 0.2 second sends DTMF.Transmission position frame can adopt repeatedly 25 (5 seconds) are sent.Promptly allow dtmf signal and voice signal at interval.
If in one minute, will send two frame position frames, can send out in the following ways:
3 (D) 15 (V), 2 (D) 10 (V) 3 (D) 10 (V), 2 (D) 15 (V) (totally 60 seconds)
If in one minute,, can send out in the following ways as long as send a frame position frame:
2 (D) 20 (V) 2 (D) 20 (V), 1 (D) 15 (V) (totally 60 seconds)
D:DTMF wherein, V:VOICE does not influence the monitoring of voice so basically.
