First, a radio unit 10 is used to transmit a message unit. As shown in the second figure, the message unit 2 is a formatted frame and contains multiple fields, which are the preamble 21, the identification code 22, and the message content. / State 23, relay sequence 2 4 and one first relayer location marker (FRLM) 25. Before the radio unit 10 generates the message unit 2 and it has not been transmitted, the radio unit identification code 2 2 and the message content / status 23 are implanted in the message unit 2. For digital wireless communication, the message unit 2 also includes a preamble 21. If the radio device 10 is a mobile device (mobi le

Page 7 480464 V. Description of the invention (5) device), the relay order 24 is 0, and the first relay address 25 is blank; if the radio device 10 is an immobile device, such as a wireless phone Master (mother machine), then the relay order 24 is 1, and the address of the first relay is 25, which is the address of the transmitter itself, that is, the address of the radio device 10. The first (possibly nearest) receiver is the radio device 12, if it receives the message. The relay sequence 24 of unit 2 is 0, then check the content of the identification code 22, if it is the same as its own identification code, it means the radio device 12 is the host of the radio device 10, which also indicates that the message unit 2 has reached its destination. At this time, the message content / state 2 3 is displayed on the screen of the radio device 12. If the identification code 2 2 is not the identification code of the radio device 12, the relay order 2 4 is increased by 1 and the first relay address is marked with 2 5. The address of the radio device 12 is, for example, the fifth Street Book Bureau π, and the rest of the original message unit 2 is copied and transmitted. The operation of the second and subsequent receivers, that is, the radio device 13 and the subsequent other radio devices, is to increase the relay sequence 2 4 by 1 and copy the rest of the message unit 2 before transmitting. In other words, in the process of relaying messages, the relay order 2 4 is continuously accumulated, and each time it is retransmitted, its value is incremented by 1. Finally, the message relay will be terminated if any of the following conditions occur. To determine whether the radio device 14 terminates the message relay, first check the content of its identification code 22 after the radio unit 14 receives the message unit 2. If it is an identification code 2 2 known to the radio device 14, then the screen of the radio device 14 displays a message Content / status 2 3 and first relay position 2 5

Page 8 480464 V. Description of the invention (6) In the case of the message relay will be terminated. The second case is to use the relay sequence 24 to terminate the message relay. When the relay sequence 24 reaches a certain threshold (thresh ο 1 d), such as 20, it means that the relay process has reached 20 stops. In order to avoid The radio frequency resources are consumed and the relay is terminated. The third case is that if the identification code 2 2 is a previously transmitted identification code 2 2 within a certain period, such as 10 seconds, it means that the radio device 14 has transmitted each other's help. Passing the same message and being adjacent The mutual aid aircraft was re-launched and therefore no longer transmitted. In the above method, each mutual aid machine determines whether to retransmit the message unit 2 according to the content of the identification code, and the host, such as the radio device 14, also compares the identification code of the message unit 2 with the identification code of the message unit 2. 2 Whether 2 is the same and then decides to terminate the relay mutual assistance. Identification code 2 2 is formulated into two types: public identification code and private identification code. For fire alarm, burglar alarm and community notification systems, publicly recognized identification codes are used for common use; on the other hand, private identification codes are both confidential and prevent others from copying and sabotaging, and private identification codes used by individuals can be transmitted one by one differently The identification code 2 2 can also be mixed with the content / state 3 3 or the relay order 3 4 into the identification code 2 2 by a specific algorithm so that the receiving end can identify the authenticity. The transmission and retransmission of the mutual aid machines adopt an asynchronous method. If necessary, the time space of the retransmission (Time Spaced Interval) is determined by the random number rule to reduce the simultaneous retransmission of message units between the mutual aid machines. And cause interference. The third figure shows an embodiment of the present invention, wherein (a) shows a specific radio device continuously transmitting the secondary message list original time (T imi ng), the second transmission time t 2 and the first transmission time

The time course of the receiver of the information source of the random number near the graph, * first number system) Same as = The time interval between the source and the received message unit 2 is about j milliseconds ^ It is left to the host to announce, and K 'is about to be transmitted, and the guarantee is less than about 5. In milliseconds, it is a relay machine that is non-signal and G. There are intervals, slashers, and periods. The random g used by each machine is determined by ^ machine, and is transmitted at the same time when retransmission, causing mutual interference. 5 relay each mutual aid machine may also be at multiple times (_ 1 other machine receives an identifiable message unit 2 at this time) J, the aggressive law (CSMA) communication law to resolve the conflict; 7 ^ zhen = xi cannot If the content of the message is recognized, the recognition and abandonment will be discarded. "Because the neighboring machines retransmit, there are random time intervals idle + machine <. The transmission source can't reach the destination several times before and after sending a message. U $ A certain channel used by this system can specify any public ^ $ will be extremely small. a of CH1. Because the system's mutual transmission of information is based on communication laws such as CT1 and forward, each sub-send (st〇re has the ability to receive and transmit at the same time, and the fi device of the same frequency does not need to be capable of Transmitting and receiving. At present, the widely used radio f-channel can be used as a wireless telephone. If a home radio is used, for example, if there is a general call in the home, a blank channel is selected so that it is a helper. When the call demands, the telephone host will perform the above-mentioned common channel use when there is no general service, but regularly switch back to the channel Y communication with the handset to send and receive the helpline telephone function.

Page 10 480464 V. Description of the invention (8) Another feature of the present invention is that temporary mutual assistance machines are allowed to join. For example, when a visitor enters a community mutual assistance area, they can request the security support of the mutual assistance system, especially for vehicle custody. When the visitor's vehicle is parked on the side of the road, the visitor registers with the security unit the identification number 22 of his vehicle handset, which may include the algorithm of his identification number 2 2. If the vehicle encounters an unexpected condition, such as a car theft, the owner of the mutual assistance system's security unit can notify the owner. The security unit can prepare a card reading device for the sub-machine users to pre-implant the card with the identification code 2 2 and the algorithm of the identification code 2 2 to log in to the main machine, so that the sub-machines entering the new community can form new mutual-assistance sub-machines. . The above method is further improved so that each mutual assistance machine may omit some mutual assistance work and the communication between the slave unit and the main unit still remains unblocked. This requires adding more stops in the message unit 2 to achieve the above-mentioned effect. As shown in the fourth figure, the message unit 3 includes retransmit (retransmit) in addition to the foreword 31, the identification code 32, the message content / status 3 3, the relay sequence 3 4 and the address of the first relay person 3 5 canceling) 36 and communication tunnel established 37, and the message content / state 33 includes public annotation, private message, and session key. (Not shown), which will be explained in detail later. In the message unit 3 shown in the fourth hidden, each mutual aid machine can cancel the relay by canceling the retransmission of 3 6 to stop the relay. Under certain conditions, the field of canceling the retransmission 36 can be directly or immediately instructed. A relay machine continues or stops the relay of the message. Terminating unnecessary relays by canceling and retransmitting 36 fields makes the communication system more efficient. As shown in the fifth figure, the host 1 4

Description of the invention (9) " ——- 1— After receiving the message unit 3 transmitted by the radio device 10, it will cancel the retransmission of the 3 6 stop and insert a sign as a known message . Once attached to the host, the slave receives a character that contains the appropriate cancellation and retransmission, and immediately stops the forward reiay behavior. This prevents the message unit 3 from being transmitted to unnecessary areas. The cancellation of the retransmission 36 not only prevents unnecessary forward relays, but also provides the function of a reverse relay. If the content of field 36 is transmitted from the main building 14 ^ ^, you can confirm whether it is safe to arrive at the main unit 14 attached to the main unit 14.

Page 12 480464 V. Description of the invention (10) 10 When transmitting the interest-bearing unit 3, the clear text (? 1311 ^ 6131) of the message content / status 33 is converted according to the private gold record and the temporary key 3 3 $. The cipher text (611 (: 口 {^ 6 (1 message), and the cipher text can be passed on to other mutual helpers: in this embodiment, the temporary key 334 used is ΠΚΕΑΑΑΠ.) Encrypt the message content / state 3 3 There are two ways. For example, first use private gold to encrypt the private message 3 3 2 plus the plaintext temporary key 3 34 into a ciphertext, and then use the temporary key in the plaintext public code 331 and the above ciphertext conclusion. 3 34 is encrypted. Another method is to use the public key 331 to encrypt the temporary key 3 34, while the private message 3 3 2 and the plaintext temporary key 3 34 are encrypted with a private key. This purpose is to maintain the private password 3 3 2 can only be decrypted by the host or the slave, and the temporary key can still be transmitted to the destination and the temporary key can only be decrypted by the host. After encryption, the slave transmits a complete frame 3 and requests a relay At this time, the value of the relay sequence 34 and the communication narrow diameter has reached 0 〇 ^ ύ 1 The nearest relay (possibly the first stop) receives the message unit 3 > makes the rest of the original message unit 2 and transmits it again.

The relay sequence 34 is continuously accumulated until the host, the host of the person) owns and The same private record of the launcher: so the shot

In this embodiment, "ΚΕΥΑΑ" was implanted at the beginning of the year, and the flying bondage was used for implantation = In Middle-earth, ^ copy the rest of the original encrypted message unit 3 to the recipient. ί The mutual helper near the host receives the key 36 :: early 3 at the interval of δτ4. By replying to the message unit 3, the mutual helper that solves the neighboring host can retrieve the common code 3 31

Siii; 111. In order to confirm the receipt, the public Daima system recognizes each other. The EEF ^ r / ^ code system, for example, '1 1 1, means that the message was accepted correctly; and the other code 卩 9, ^ # indicates the current situation Urgent and so on. By comparing the previous reception identification = "confirmation code " 1 1 1 '', the neighboring radio device determines that the relay master ^ ^ safely receives the message of its slave ', so there is no need to perform the forward direction, the & Let 'in order to assist the host to establish a two-way transmission path, perform a reverse relay and send its reply message unit 3.

The relative position of each relay between the slave and the main unit has not changed. 'Then reply to the message unit 3' will relay one stop one stop, that is, from the tenth stop

Page 14 480464 V. Description of the invention (12) Return to the ninth station, the eighth station, etc., so that each station spontaneously transmits a reply message unit 3 ', that is, performs a reverse relay, and the message unit 3' will pass through its original communication. Path back to somewhere near the handset. If the handset also has the ability to receive, by confirming the cancellation of the message unit 3 'and retransmitting the contents of bit 3 6 can ensure that a two-way communication link (communication link) has been established. Thereafter, a field of 37 has been established in the communication narrow diameter. Can be implanted to show the communication of two-way transmission path. Narrow diameter should be established. If the value of the communication narrow diameter has been set to 3, the value of 1 is forced to stop the relay that is not on the reverse relay path to stop the forward and reverse relay. According to the possibility of receiving a clear radio signal, it is only in the geometric position. The mutual assistance machine between the master and the slave participates in the relay. This implantation will greatly reduce the number of radio devices participating in the relay and the spectrum usage in an area. This method will further restrict the bidirectional transmission path to bidirectional transmission π narrow diameter π. In the future, when the slave unit transmits the message unit again, the narrow diameter of this communication is likely to be used again. The temporary key 3 34 can be different each time, and only the slave and the host can hold the private key, that is, only the host can crack the encrypted message unit 3 and the temporary key 334. It is not easy for a third party to use the key without the private key. Under the circumstances, the temporary key is released or the message unit is transmitted as a transmitter, so the security and reliability of the communication can be more guaranteed. In addition to maintaining the security and reliability of communication, the two-way transmission achieved by the above methods can establish a virtual communication narrow path and save communication resources. If the virtual narrow path is not established, the transmission of the message may be launched in all directions with the slave as the center, and it will be transmitted outward through the relay in sequence. However, because the host is only in one direction, the relay in other directions will be

Page 15 480464 V. Description of the invention (13) It becomes wasteless. By establishing a narrow communication path, communication resources can be used more effectively. If the slave set communication narrow path has been set to 1, the radio devices not in the communication narrow path will not participate in the relay transmission message, so unnecessary communication resources can be saved. The use of the same identification code 3 2 is extremely important for the establishment of a narrow communication path. For successive message transmission, the slaves only use the same identification code 3 2. When the host sends the reply message unit 3 ′ through the narrow diameter of the communication, each mutual aid machine can compare the records of the identification code 32 of the message before and after. Therefore, the mutual assistance machine can judge its role as a forward relay or a reverse relay based on its past transmission and reception records. In some special cases, such as the change of the radio wave environment or the different handsets handling the mutual assistance transmission in their neighboring areas, the degree of busy recording of each relay machine varies from time to time. At this time, the receiver may not be able to receive messages due to busy recording, so the virtual communication narrow diameter may be temporarily unavailable, and the slave may not receive any response. In order to solve this problem, the field of communication narrow-path already established 37 is returned to 0, which means that you need to request the support of other mutual aid machines to re-establish the communication narrow-path. Continuing the above-mentioned embodiment, for the message unit 3, the process of generating from the transmitted machine via the relay machine for mutual transmission to receiving by the host can be shown in the seventh figure. Transmitter A generates message unit 3 in step S10. The message content 3 3 in message unit 3 includes public code 3 3 1, private message 3 3 2 and temporary key 3 3 4. After step 12, the message unit 3 3 is converted into cipher text, and after that, the message unit 3 is transmitted in step S14, and finally received by the radio device X. If the radio device X is not the host of the transmitter A, the message units 3 each

Page 16 480464 V. Description of the invention (14) The value in the field (14) will determine the response of radio X. When the relay order 3 4 in the message unit 3 is less than a fixed value, for example, a preset critical value, then step S 1 6 is performed to increase the relay order 3 4 by 1, which is a typical case in which the value in the relay order 34 is 0, which means that the radio device X is the first relay of the message unit 3. In addition to the relay sequence 34 plus 1, it also includes inserting the address of the radio device X in the first relay address identification field 35 and copying it. The information in the other fields of message unit 3 is then sent out, so the relay is repeated.

give away. When the relay order 34 of the message unit 3 is greater than the current critical value in step S14, that is, the situation shown in step S18, it means that the message unit 3 has been transmitted by many relay machines but has not yet been received by the host. In order to avoid consuming communication resources , The relay is terminated, that is, step S 2 0. The discussion in step S 2 2 is another case, that is, when the communication narrow diameter of the message unit 3 has been established 37 and the field 7 is 1, according to other stops in the message unit 3, such as the identification code 32, the non-electric device X judges the previous When the original message unit of the message unit 3 has not been transmitted, it means that the radio unit X is not on the path of the previous communication of the message unit 3, in other words, the radio unit X does not need to transmit the message unit 3 again, so the message unit The relay of 3 is terminated, that is, step S20.

If the radio device X is the host of the transmitter A, the cipher text of the received message unit is restored to the plain text and the temporary key, that is, step S 2 4. Then, the canceling and retransmitting field 36 of the message unit 3 is implanted with a temporary key, that is, step S26, as a sign that the message unit 3 has been received by the host. Then, step S28 is performed, after the data of the other stops are copied by the radio device X, the message unit 3 is transmitted.

Message unit 3 transmitted by radio device X is adjacent to radio device Y

Page 17 480464 V. Description of the invention (15) Receiving, the role of the radio device Y will affect the change of the message unit 3. If the radio device Y is the transmitter A, proceed to step S30 to implant 1 in the communication narrow-diameter setting field 37 of the message unit 3; if the radio device Y is a relay machine that previously transmitted the message unit 3, proceed to step S32 To confirm that the original message has reached its destination safely, and then transmit the message including the temporary key, step S 3 4 to complete the reverse relay. This process is repeated iteratively. If the radio device Y is not the previous relay, the transmission of the message unit 3 with the temporary key implanted is terminated, that is, step S36. This step can be performed by using the identification code 3 2 of the message unit 3 or comparing other field data. Recognizable. The eighth figure further describes the role of the radio device in this mutual aid system and the process of the radio device receiving different messages under different conditions and reacting differently. For ease of explanation, each radio device can be based on its different environment. The status is distinguished as the originator or relay / recipient of the message. The former generates the message unit 3, that is, step S40, and it has 丨! The private key encrypts the message content of the message unit 3 into a ciphertext as the ciphertext message unit, that is, step S42, so that the message unit is not cracked by others. After transmitting the message unit 3 in step S44, the operation of the transmitter is terminated. On the other hand, the relay / recipient refers to the person who is not the originator of the message and plays the role of either the relay or receiver of the message unit 3. After the relay unit receives the message unit 3, it identifies whether it is the destination (ie, the host) to which the message unit 3 is intended to transmit. This is steps S50 and S52. This identification is based on whether the relay unit recognizes the ID column of the message unit 3. If the result of step S52 is YES, it means that the relay shoulder is the host of the transmitter, then step S 5 4 is performed to extract the original text of the message unit 3 and the temporary key, and then cancel and retransmit the message unit 3

Page 18 480464 V. Description of the invention (16) A temporary key is implanted in the field, that is, step S 5 6. This can prevent further forward relays and reverse relays, and then send the message unit 3 out-ie, step 5 8 .

The foregoing process is directed to whether the relay is a host. If the result of step S 5 2 is no, it means that the relay needs to wait for the time interval of △ T 4 to try to receive the message of canceling and re-transmitting. This judgment process is step S 60. If a message is received and retransmitted during the time and interval of AT 4, it means that the relay message unit has reached its destination, and the forward relay can be cancelled. At the same time, the relay machine will replace the previously received message with the same ID. The forward relay message includes canceling the retransmission key, step S 6 2 and performing the reverse relay. After the replacement process, the message unit 3 'is transmitted, that is, step S64. If the result of step S 6 0 is no, it means that the host of the relay machine | did not receive this information unit 3, and then the relay machine further checks whether the relay order 3 4 of the message unit 3 is 0, that is, step S 6 6. In this step, the relay machine knows whether it is the first receiver of the message unit 3. If the result is yes, then step S68 is performed, and the first relay location of the message unit 3 is marked with 35, which is inserted into the Position; if the result of step S 6 6 is no, the relay is convenient for directly adding 1 to the relay sequence 3 4, that is, step S 7 0, while copying the other fields of the message unit 3, and then transmitting, that is, step S 6 4.

Using this system to develop wireless "consulting" applications, mobile computers can use the consulting method to capture useful public or private information around them. For example, this application is very practical when the owner of the car wants to find out where the car is located in an unfamiliar place. A publicly recognized service device can broadcast the specific location of the device.

Page 19 480464 V. Description of the invention (17) After receiving and interpreting the transmitted information correctly, you can determine its position in words. For applications where accuracy is required within a hundred feet, this is the most cost-effective location service. Wireless consultation can also allow water and electricity companies to use wireless meter reading. For example, a meter reading car can be driven near the user to inquire about the readings of each meter. Using mutual assistance, multiple readings can greatly increase the distance between meter readings. For consulting clinics or first-in-first-serving restaurants, the consultation function is also very useful. The clinic or restaurant can broadcast the waiting time or service serial number. Any patient or customer can use the mutual aid machine to know the service number status of the clinic or restaurant in the range where the radio waves can reach the clinic or restaurant when they approach or the range where the radio waves reach after multiple relays. Based on the characteristics of the mutual assistance machine, the consulting function can be completed in the active mode or the passive mode. For example, if the driving owner wants to inquire about the current location of his vehicle, he can enter the text “REQ FOR L 0 Cπ” in the message content / status 33 field to request the positioning service. A nearby mutual assistance point will recognize this as The positioning request is no longer used to transmit the message unit by relay service. At this time, the receiver with the ability to broadcast the position responds to this request and displays the position in the message content / status field. The position responder is different according to the general relay rules. Using different response time ΔΤ5, each response signal will not appear at the same time and conflict will occur. The consulting machine will then receive and judge the data of the more reliable location, this is called active query service. Another kind of active consulting service is for the hydropower company. Meter reading.
