Specific embodiment

Below in conjunction with accompanying drawing, case study on implementation of the present invention is further described.

Based on the communication means of ring time space coding, it is to carry out under the hierarchy shown in Fig. 1.The present invention carries The wireless channel framework going out is referred to as layered framework, including physical layer, channel layer, coding layer and application layer.Wherein physical layer is by two Individual intelligent mobile phone terminal equipment is constituted, and here, we have can phone functions discarded using no network function but still Smart mobile phone.Channel layer refers to the basicly stable reliable wireless channel using MCET technique construction.Coding layer comprises two parts, A part refers to carry out containing the coding work detecing wrong function of correcting mistakes for the information that will transmit, and to volume on the basis of coding Code carries out reasonable compression；Another part refers to that the coding for receiving from channel layer is decoded.Application layer can pass in theory Defeated types of applications information.

The information wireless channel technology of the present invention includes herein below：

Construct hierarchy framework, that is,

1. physical layer：Discarded smart mobile phone assembly；

2. channel layer：The wireless channel of MCET technique construction；

3. coding layer：Carry out containing the coding detecing wrong function of correcting mistakes, the letter that channel layer is received for information to be transmitted Breath is decoded；

4. application layer：Carry out the application as transmitted location information, certainly, during transmission location information, need the handss of physical layer Machine has positioning function.

Taking transmit location information application as a example, macroscopical flow process is as shown in Fig. 2 installing related application in female terminal and being arranged to Female terminal role, sub- terminal is installed related application and is arranged to sub- terminal role, and female terminal clicks on related application button, transmission prison Control locational requirement, female terminal sends to sub- terminal and obtains location information demand, and sub- terminal calls localization function module, obtains in time Location information, location information carries out efficient coding, and the location information after encoding is transferred to female terminal by sub- terminal, and need to avoid doing Disturb signal, the coding that sub- terminal sends over is decoded by female terminal, and invocation map module, and location information is carried out visually Change display.

Physical layer：

Physical layer is made up of two intelligent mobile phone terminal equipment, here, it is possible to achieve no network function but still have beat The recycling of the discarded smart mobile phone of telephony feature.As shown in figure 3, there being two intelligent mobile phone terminals to be referred to as female terminal With sub- terminal, when female terminal is to sub- terminal transmission information request, female terminal is transmitting terminal, and sub- terminal is receiving terminal, group terminal When feeding back to female terminal, sub- terminal becomes transmitting terminal, and female terminal then becomes receiving terminal.

MCET channel layer：

The main challenge point of this method is that and can not be passed by network nor by note or any form of spending Defeated information.It is therefore proposed that Missed Calls Encoding Technology (MCET) technology, and put up in physical layer In the case of use.This layer have invoked smart mobile phone call functional module, and assume that female terminal sends the sub- terminal position of acquisition When putting information requirement, and obtain in the whole process of location information, it is called, and function is occupied, using the phone collected Sigtnal interval enters the transmitting procedure of row information coding, and solution is as shown in the Organization Chart of Fig. 4 front and back end.If monitoring mother Terminal is taking phone functions, then delay GPS location transfer function, until monitoring that female terminal phone functions just locate In idle state.

As shown in figure 5, due to process transmission information of making a phone call, needing a stable phone make and break process, especially, send out Telephone communication UNICOM Time_interval time delay of sending end and receiving terminal will be consistent it will be assumed that transmitting terminal and connecing Two environment residing for receiving end keep constant, and that is, the semiotic function of signal of communication tower is constant, the external world such as weather wind speed and building ring Border is unchanged, and under such supposed premise, phone UNICOM Time_interval time delay of transmitting terminal and receiving terminal is steady Fixed.In this case, transmitting terminal dials some logical " phones of access failure ", " access failure that receiving terminal receives to receiving terminal Phone " is spaced, as the information of channel layer transmission.

Coding layer：

Coding layer includes the flow process of information coding to be passed and decoding, for location information transmission, for making final position Put position error scope within 1 meter, the latitude and longitude information precision of transmission will remain into five after arithmetic point.Information coding is taken The mode of differential coding, obtains the longitude and latitude of sub- terminal position by alignment system, if pair warp and weft degree is directly carried out Binary coding, code length can be long, and therefore we are encoded using difference, the longitude and latitude of as sub- terminal position Make the difference with the basic point in current active region, thus can shorten binary-coded length.Location information coded format such as Fig. 6 institute Show, including transmission notice prefix code, error detecting code, longitude code, error detecting code, latitude code, wherein notify prefix code to be first group of volume Code, the error detecting code of longitude code and longitude is second group of coding, and the error detecting code of latitude code and latitude is the 3rd group of coding.

Coding translation can in the way of being combined with the translation of phone space coding using time interval coding translation (hereinafter This coded system when being called m- telephone booth every coded system).

(1) time interval coding translation

Time interval coding translation, for realizing three notice prefix codes of transmission, sends a signal and (beats in the unit interval Take on the telephone) corresponding coding 1, do not send signal and correspond to coding 0.

In female terminal, the interpretative system of acquiescence encodes for time interval, until the notice prefix code receiving occurs 111, then All coding interpretative systems after this coding are converted to phone space coding.This time interval can use Time interval (unit For s) being indicated as parameter, Time_interval can be selected under present case, and mother and sons' terminal carries out the signal of telephonic communication Time delay it is assumed that this time fixing and effectively under current environment.

(2) phone space coding translation

Encode interpretative system in view of according to time interval, often take on the telephone and be often separated by this time of Time_interval Afterwards, it is only capable of expressing an information, and the positional information of sub- terminal needs 40 codings altogether, then overall translation transmission time reaches So long, at most 41 take on the telephone 40 × Time_interval, and translate to record sub- terminal using phone space coding Positional information can shorten translation transmission time and reduce the quantity made a phone call.

Because phone number of times is more, the probability that transmission error occurs is bigger, so considering phone number of times and total duration, More appropriate using 4 coded systems.

Frequent activities area preference encodes：Frequent activities region be sub- terminal in daily life frequent activities region ground Location, record frequent activities region as monitored in students' union is the address of school and family.Preferential for frequent activities regional code Translation, macroscopic view can reduce the communication time encoding.

In view of transmitting the longest duration of one group of positional information by the way of 4 coding translations up to 210s (10* (t+ 15)), and the zone of action of sub- terminal is relatively fixed, then the rule of the preferential translation of design frequent activities regional code is to reduce The probability transmitting the longest duration occurs.

Extract the regional address (as school and home address) of sub- terminal frequent activities first, inquire about the longitude and latitude of this address Information, obtains the address information coding of at least two group of 40 bit length after Information Compression and information coding.It is encoded to 4 Unit, this two group of 40 bit address information coding is segmented into 20 groups altogether, then this 20 group is carried out with descending, frequency Rate highest coding is preferentially translated as being spaced Time interval, is secondly Time_interval+1s, by that analogy.

To sum up told, sub- terminal first completes information setting, obtain frequent activities area preference coding translation table, female terminal is The location information of sub- terminal can be obtained according to location transmission flow process.

Application layer：

The scheduling mechanism of fixed position information transfer is as shown in figure 8, if fruit terminal is in small area, be then directed to it The coding of the latitude and longitude information in frequent activities region uses frequent activities area preference coding principle, calls the electricity in MCET technology Words space coding, leads to number and the phone functions module every calling mobile phone end for the telephone booth according to the phone after coding.As fruit eventually End activity in big regional extent, then need storage area ID in advance, calls area code to prestore module, and according in MCET technology Differential coding mechanism carrys out transmission information.

Need to call MPTM model during dynamic position transmission, as shown in figure 9, now, the mobile state of terminal of movement is divided into " standard mobile status " and " non-standard mobile status ", non-standard mobile status takes the differential coding machine similar to MCET System, during transmission difference coordinate, need to choose certain time interval, " standard mobile status " then takes standard mobile coding mechanism, This mechanism only needs to transmit command informations such as " left-hand rotations ", " right-hand rotation " and " turning ", and transmitted data amount is little.At the beginning of during execution MPTM Phase, the starting point of sub- terminal of needs transmission movement, the speed of sub- terminal of movement, initial moving direction of mobile sub- terminal etc. Information, during the crucial mobile change such as moving direction and rate travel afterwards, need to send changing again.

Because MPTM process be movement sub- terminal, therefore send information when it is noted that the propagation delay time divide Analysis, the distance value that sub- terminal speed × propagation delay time ≈ is late, the GPS location that female terminal receives need to consider that this is late Distance value, error can be reduced.

Wherein, when the sub- terminal speed of movement is changed, then the speed after change is transmitted again, if sub Terminal speed is constant, only carries out turning to movement, then have two kinds of scenes to be that standard is mobile and change and non-standard mobile change.

(1) the sub- terminal of movement carries out the mobile change of standard, then adopt standard mobile coding mechanism

During the mobile change of standard, sub- terminal positional information, movement rate and the direction of motion are carried out completely for the first time Property transmission, only need to when there is crucial mobile change afterwards, the speed that transmission changes and the direction changing.

(2) the sub- terminal of movement carries out non-standard mobile change, then adopt the differential coding mechanism under MPTM

During non-standard mobile change, sub- terminal positional information, movement rate and the direction of motion are carried out for the first time Whole property transmission, afterwards at interval of 5 minutes, sends the differential coding content of shift position, this difference is the current location of sub- terminal The difference of the positional information sending with first time.

It is emphasized that embodiment of the present invention is illustrative rather than determinate, bag therefore of the present invention Include the embodiment being not limited to described in specific embodiment, every by those skilled in the art's technology according to the present invention scheme The other embodiment drawing, also belongs to the scope of protection of the invention.
