Description

Low-cost wireless monitoring method based on mobile communications network
Technical field
The present invention relates to remote wireless monitoring technology, wireless communication technology, the network communications technology, software engineering, specifically be meant the wireless monitoring method based on mobile communications network of a kind of low cost or zero cost.Belong to information technology and wireless monitor field.
Background technology
At present, known wireless monitoring method is meant: utilize self-built special wireless network or limited shared wireless network, the monitoring that monitoring side implements monitored object, for example conventional method such as microwave monitoring system, radio frequency monitor system; The method that also has some to utilize existing mobile communications network to monitor in addition, for example GSM alarm, GPRS remote power environmental monitoring system etc.
For utilizing self-built special wireless network or limited shared wireless network to implement the method for monitoring, the user needs oneself to build wireless network, and construction investment is huge, and the maintenance for network simultaneously also needs great amount of manpower and material resources.
Secondly, for the method for utilizing existing mobile communications network to monitor, it is the remote wireless monitoring that utilizes SMS (Short Message Sevice), GPRS (General Packet Radio Service), IVR (Interactive Voice Response) or pure voice channel mode to implement that the wireless monitoring method in for example present GSM, CDMA and the PHS network does not have outer.Because the monopoly of mobile communications network resource, in the practical application based on the method for supervising of mobile communications network, communication expense still can be in any more at present.Use cost is too high to be to hinder a lot of wireless monitors to use the principal element that can't popularize.For example GSM automobile or household alarm can realize that long distance wireless reports to the police, but high usage charges are hung back a lot of users, also make much to have used the user of a period of time to abandon gradually using.Therefore, still well do not used and popularized based on the wireless monitoring method of mobile communications network at present, do not obtained sufficient industrialization and scale yet.(writing the China Youth Press referring to waiting of " remote wireless monitoring technology " model ease publishes)
Simultaneously, for the method for utilizing existing mobile communications network to monitor, as present GSM, wireless monitoring method in CDMA and the PHS network is to utilize SMS (Short Message Sevice), GPRS (General Packet Radio Service), in IVR (Interactive Voice Response) or the pure modes such as voice channel, monitored object side and monitor supervision platform side need complicated circuit to carry out signal processing, if communication functions such as superposing voice prompting, then make circuit structure relatively complicated, increase a lot of potential fault points simultaneously, significantly reduced the reliability and stability of product and system.For example present GSM automobile or the household alarm that occurs on the market, after the user dials main frame number and connection, how have the automatic speech prompting user operates, but because external physical environment (for example field intensity, temperature etc.), signal interference etc. are all multifactor, or baffledly a period of time of after go out the situation that realize voice disappears having used.This is the common problem that this series products is used, and has influenced product quality and user's reliability greatly.
Summary of the invention
In order to address the above problem; the present invention aims to provide a kind of low-cost wireless monitoring method based on mobile communications network; utilize this low-cost wireless monitoring method can significantly reduce real-time, reliability and stability that communications expense, raising transfer of data and other function in the wireless monitor application realize easily and effectively based on mobile communications network; allow based on the wireless monitoring method of mobile communications network more flexibly, the scope of application is wider; and be easier to universal and popularization, thereby form the industrialization and the scale of this application.
One, reaches effect in order to achieve the above object, it is a kind of cheaply based on the wireless monitoring method of mobile communications network that the present invention solves technical method that its technical problem adopts, its primary and foremost purpose is: reduce monitoring side user's monitoring use cost, comprise following feature and step:
1.1 the mode that monitored instruction produces
The mode of monitored instruction is whether to realize by caller in the mobile communications network and called communication request link establishment among the present invention, and the switching value that whether produces ring of the communication terminal by the monitored object side is used as monitored instruction and carries out exercises with the actuator of control monitored object side specifically.
When monitoring side implements policer operation at needs to monitored object, call by certain rule to the communication terminal (called) of monitored object side as caller by the communication unit of monitored object side earlier, after this caller communication request link establishment, communication terminal in called monitored object side promptly can produce called ring, but do not produce conversation this moment, and the foundation that also is this caller communication request link provides the mobile communication carrier of service not begin to charge at this point.
Subsequently, after the communication terminal of monitored object side produces called ring, after monitored object side or the affirmation of monitoring side interlock circuit, allow communication terminal or monitoring side hang up the reception and the transmission of this time calling out immediately to finish signaling.
1.2 signaling rule
In order reaching the remote monitoring object to be implemented various supervisory control actions, just monitor command must to be carried out encoding and decoding in a manner described.Because the mode of monitored instruction is whether to realize by caller in the mobile communications network and called communication request link establishment among the present invention, be switching value therefore, can be understood as 0 and 1.
But because the settling time of caller communication request link is relevant with several factors, the network condition of several factors and mobile communication carrier is associated, but can not have this method to grasp.Therefore monitor the transmission means of signaling and be not suitable for real-time or synchronizing capacity requires very high application, but enough for general civilian application.
1.2.1 simple rule
For the monitoring that only needs switch motion, the signaling rule is very simple, can whether be consistent with the foundation (called terminal ringing) of communication request link or opposite, and note the number of times of dialing, carry out switching manipulation by the parity of dialing number of times by monitoring side and monitoring side.For example the n time ring, system definition is " opening " operation, and then the n+1 time ringing system carried out " pass " operation; In like manner the n time ring, system definition is " pass " operation, and then the n+1 time ringing system carried out " opening " operation.
1.2.2 complex rule
Must assign the situation of complicated monitor command for monitoring side, at first need to select a tame mobile communication carrier (as China Mobile, CHINAUNICOM, China Telecom etc.), and according to its network condition and switch characteristic, obtain setting up caller link () shortest time Tmin and maximum duration Tmax also promptly: carry out making call to cried the generation ring by terminal from caller, if the communication terminal of monitored object side is t from producing ring to the time span of hanging up this time communication linkage (call request), the communication terminal of establishing the monitored object side again is f to the sample frequency of bell signal, then must satisfy relation: (Tmax-Tmin) f<=1; F<=1/t.
After the condition more than satisfying, encode for the mode that the monitor command of monitoring side just can machine code, coding rule is applicable to all decoding method systems of present main flow.Simultaneously, monitored object side fibrous root carries out decode operation according to identical decoding method system, and carries out the monitor command of monitoring side.
1.3 the utilization means of CRBT, CRBT (caller ring-back tone)
For under the state of not setting up conversation, be under the free state, can guarantee that also the user obtains voice service, the invention provides by set the method for special ring-back tone in the network of relation side of mobile communications network, to allow the user obtain the voice service of hommization, the while has significantly been reduced the use cost of mobile communications network.The present invention can adopt multiple Ring Back Tone Technology, comprises multimedia color ring back tone, IP CRBT or the like.
Must feed back to the quantity of state of monitoring side 1.3.1 determine the monitored object side
After monitoring side implemented the various operations of monitoring to monitored object, normal conditions monitoring side need obtain the feedback of monitored object.Before the caller ring-back is set, must determine the quantity of state of monitored object side feedback earlier.For example: if need only be " opening " or " pass " to monitoring side's feedback states, then quantity of state be 2; If must feedback " just ", " bearing ", " zero ", then quantity of state be 3, and by that analogy, and to establish quantity of state be n.
1.3.2 the segmentation of caller ring-back tone
If the communication terminal of monitored object side is t from producing ring to the time span of hanging up this time communication linkage (call request), and the monitored object side must to feed back to the quantity of state of monitoring side be n, t is divided into t1, t2, t3......tn.
1.3.2.1 the cooperation of state
At first, the maximum length of setting this mobile communications network caller ring-back tone is T, must satisfy t<=T.
Secondly, if the monitored object side must allow monitoring side learn quantity of state 1, the then t1 time period active on-hook that the communication terminal of monitored object side must be in t; In like manner, if the monitored object side must allow monitoring side learn quantity of state n, then initiatively on-hook of the tn time period that the communication terminal of monitored object side must be in t.
1.3.2.2 the period is cut apart
To cutting apart of t day part, can take 3 master slave modes: the first, all point-score, i.e. t1=t2=......=tn; The second, voice precedence method, promptly when the caller ring-back tone is set, the suggestion voice length of different conditions is not quite similar, for example " shut down " and the voice length of " your second set up defences the phenomenon that the zone has temperature anomaly to raise " is different, for the user hears complete voice, just n condition prompting time must be set according to voice, if the backchannel duration of a sound of n state, the tn of then cutting apart is long; Three, monitored object state time delay precedence method, the quantity of state (all or part of) that the monitoring side must be fed back has time delay under many circumstances, sometimes the caller ring-back tone need be waited for the generation and the execution of this quantity of state, at this moment must be foundation just, be provided with and cut apart the caller ring-back tone with the time delay of monitored object side.
1.4 interactive monitoring
If the phrase sound prompt time of each state of monitored object is Tmin, if T/n<=Tmin then can not satisfy the simple requirements of above method for supervising, under requiring cheaply, just must expand above method for supervising.The method that the method for its feedback signaling and monitoring direction monitored object send the monitoring signaling is similar, and just the signaling by the passback of monitored object side is not a monitor command, but the relevant information of feedback states.In this manner, the caller ring-back tone of setting only plays the aid prompting effect, and easily carries out various data processing according to the encoding and decoding that above-mentioned signaling rule is carried out, and implements the various application of various the Internets.
