Description of the invention α) [Technical Field of the Invention] The present invention relates to a method and device for a decentralized wireless communication network and its main control system, and particularly to the security of transmitting digital data with audio and video information using a wireless network And the method of digital ^^ message ^, ----------------________- --'——, [knowledge technology] With the popularization of digital communication systems, the need for high-speed connection of audio, video and other digital Information requirements are increasing. Currently, digital networks based on wired transmission are providing the best solution to meet these requirements. Because this digital wired network has broadband carrier power --------------- -------~-* ----- this is sufficient for another traditional wired network architecture is the wireless communication network, For example, networks based on radio wave (RF) transmission. Wireless data transmission is used in the place of traditional wired connection, using radio waves or infrared light waves' — * — —--- 1 " " — — to communicate between the user and the device. Although the wireless system allows — ~ ^ _______ users to have more flexibility to reduce the use of electrical wires to connect to the desired network area, the wireless system will lag in terms of achieving the aforementioned high-speed and high-data-rate transmission requirements. . At present, wireless networks are extremely suitable for communications that can be ignored, which are not complicated, do not require security protection, and do not require immediate attention, but these are not attractive. ϋΐ All: Wired network architecture, because the wired network can securely convert multimedia information according to demand. For these reasons, traditional wireless network architectures are rarely considered as an alternative to wired networks. -The greater disadvantage of traditional wireless networks is: available radio frequencies

The rate range is gradually decreasing. The so-called beneficial radio waves (Spectrum) are used in the United States to divide its range of use, such as: Channels, TV and radio channels are used in different countries, but the correct frequency is set in each country and not in the wave range. The required number of channels is the frequency range of the cable, which is generally referred to as the use of mobile phone channels, satellite communications, etc. by the government within the country. Similar-purpose channels are also used in their various channels. Because it is in a limited radio ‘so’ it can be used in wireless networks. With the advent of spread spectrum technology, wireless network systems have been developed to provide reliable data transmission in noisy environments. These technologies use a wider bandwidth than the required baseband signal. When such a system operates in a radio frequency with noise, it can be used most effectively in other radio waves without noise through frequency regeneration combination. Spread frequency has been defined in the latest IEEE Standard Specification for Motors and Electronics (Fifth Edition), which is defined as follows: A multiprocessing or anti-noise and anti-interference frequency modulation technology. (Such as a dummy noise code), the frequency of the j is often seen, and the color is g ^. The receiver compensates to the original signal size after performing a handshake with these signals. At present, most of the spread spectrum network systems rely on a central base station 'or a master radio wave transceiver (hereinafter referred to as a transceiver) that has all-digital communication in a predefined area. This form of wireless system is like home wireless phones and ordinary cellular mobile phones. Usually come

Page 5 475321 V. Description of the invention (3) Says' This type of system contains at least one base station, and the base station will use one to establish a communication channel for one or more remotely controlled or controlled transceivers to perform Communication with the master transceiver. Regardless of whether the radio signal is received or transmitted, the master transceiver controls the link between each dynamically controlled transceiver in the range of use. Therefore, each controlled transceiver must be paired with a master control transceiver. One of the main pairing methods of the Central A Chinese network when operating in an environment where radio waves have been restricted is that the master transceiver can only communicate with its paired controlled transceiver within a certain period of time. When the number of simultaneous networks is increased, the inherent architecture will reduce the speed of each data link, so that the above-mentioned conventional technology will be appreciated. [Summary of the invention], "can reduce the danger of eavesdropping and avoid the use of wireless networks without consent. There are ^ ^ ΐ :: The point is to be able to maintain a group of transceivers in a wireless network, and here A wireless network group can transmit data between two or more transceivers. A further advantage of the present invention is that it can use any element in the wireless network in accordance with the present invention to be used in A communication network with at least another transmitter-receiver device. The purpose of this disclosure is to allow another aspect of the invention to propose a secure i-free network.

475321 V. Description of the Invention (80) "-The second layer of the protocol is directed to the instructions and events of the call sequence. All commands and events are transmitted through the T-Mux packet transmission channel. The signal ranges of multiple connected T-Mux packets are combined into an information element control block. Using these commands and events, the call processing software can provide the user-defined features. The system can handle standard and super standard functions and features. There are usually two types of phone requests, namely phone call and programming. Telephone requirements for telephone calls involve two or more users. Therefore, links must be established to provide communication between users. If the participating users are using mobile phones, the communication link is a radio frequency channel. If one of these participants is a remote user, an additional communication connection using a public switched telephone network is required. After the foregoing, the system must perform the call setup process and connection management. The types of calls are, for example: outside dial-in, internal dial-out, start of internal call, end of internal call, automatic dialing, transfer, hold, redial of the last group number, and speed dial using the built-in directory. Only one user can participate in the call request of the program editor, that is to say, this terminal device is the user who wants to set the program. Therefore, no communication connection is required at this time, and the terminal device also allows the user to modify his or her own database. The aforementioned database includes the identification of the security password, the identification code of the terminal device, and the index and telephone number of the speed dial. Because the system parameters are unique to all terminal devices, they have the ability to allow users to register, modify, and verify the program editing of the database. One of the aforementioned features is the security password.

The terminal device identification of the base station ranges from 0 to 11 and the range of the identification code of each mobile phone is between " and 99. For each terminal device, the number of dialed telephone numbers can be 碣, and the telephone number of the aforementioned speed dial number can be a maximum of 16 digits. 8 · 11 call office / call a news agency. Extension / Beer 'only the terminal device itself', so no channel connection is required; between two devices one to one words must occupy two terminal devices, in these two terminal A and fixed channels to provide communication, but no public network is required (PSTN) for communication. In the communication of the platform = ΐ, from the main control device to the controlled device, the block diagram of this step, in addition to adding some additional two types of cooperative calls; :: Figure 12. As for the outside dial-in call and the inside dial-out channel to provide communication: a frequency is needed between the m mobile phone and the base station-channel A, g is used between the base station and the public switched telephone network. The base station is the main use. In the case of an outside caller, the role is set. On the other hand, the mobile phone acts as the corner of the controlled device. In the case of two outgoing calls, the mobile phone acts as the master device and the base station plays the role of the controlled device. ; Evening line incoming call (i / c) and internal line outgoing call (ο / e)

Page 84 475321 V. Description of the invention (82) The base station works with mobile phones and public switched telephone networks. That is to say, the two operate in source pairing and terminal pairing modes. Therefore, there are two sets of transmission states during the call.

Described in _ 8 · 11 · 4 Clearing operations There are several different clearing processing modes in total according to different interruption situations. Only two parties involved in the call are connected, and the rest are as follows. Yes, China. These situations will be detailed i: This is a complete comparison, one party hung up the phone. This 13-on // brother occurs when the above-mentioned hang-up action is detected during a two-party conversation. The 7-shape can be regarded as a general interruption situation. If this is a peak, the end of the second hang up will start to clear the call.

， 1 = ， x set is the public exchange telephone network will become the initial end. The initial interruption work items that must be controlled are: interruption call path, invalidate C (| DEC, release frequency channel, enable transmission and reception. Invalid and return status. For the controlled device ^, its initial state is in the sleep state, and for the initial state of the master device, it is a redial call sound. •: This condition can be regarded as a break. IΪ means that although the communication The channel has been established, but the communication channel has not yet been established. The interruption work includes: releasing the frequency channel, and receiving is invalid, and returning to the original state. 3,: This condition indicates that the communication connection establishment failed.

Recognition ^ This condition indicates that during the call, the identification code handshake process failed. The sound data and control data All of them are no longer valid. The interruption work that must be completed is to evacuate the connected bearer to release the frequency channel, invalidate transmission and reception, and re-execute at the master control device. The connection state is the same as the channel, and returns to the original 2 other terminal device at the controlled device side. In this situation, there is no need to release the call path ^ connection ·. If the phone hangs up, keep the microphone on ^ When the signal enters the sleep state, it returns to the initial state and waits for the call request to sweat or enter. When the call loop becomes open loop, it can be detected that a discontinuity has occurred between the base station and the eight-switch telephone network, in other words , Jane = Mody pay e N Ci Suspended

I ° Install w at both terminals to determine. If the message is disconnected or not, the communication between the microphone and the terminal device is detected. In addition to the speaking channel, the call will be cleared to the i channel in the two interrupted calls.)

Page 90 475321 V. Description of the invention (88) There are two: first, to prevent the system from being misused abnormally, and second, to avoid another group using the same preset system security identifier and setting duplication as much as possible Terminal device identification number. The present invention has provided an easy and flexible mechanism for changing and / or verifying the security identification code. Because all terminal devices in the same group will use the same system security ID ', once the user decides to change the system's security ID, all terminal devices must also be changed accordingly. Since a terminal device cannot communicate with a terminal device with a different system security identification code, the security identification code is like the password input before the terminal device, so the security identification code must be memorized. There are three ways of program editing to allow "'users to operate their security identification code: first, set the security identification code to a pre-empted value" "0 π; second, change the security identification code of all terminal devices; first, change Individual security ID. In addition, there is a command to verify the registered security ID. The following sections will describe these operations in detail. 11 · 1 · 1 Change the system's security ID to a preset value. The security identification code is "0". This default value allows users to make normal calls after purchasing the phone system. Users can change their security identification code after they become familiar with this phone feature. When the user changes their system security identification code, it may be possible to cede the Mima content. In this case, because the new terminal is installed with the system security identification code, the user cannot install a new terminal device. A quick and easy remedy for this guy is to set the system's security ID back to its original default value. Anyway, thanks to the new security ID

V. Description of the Invention (113) The function of a conference call for multiple users. The invention of the bi-orthogonal electrical signal has at least 30 years of history, but because its electrical signal characteristics are similar to the orthogonal electrical signal, and the orthogonal electrical signal does not require an absolute phase reference level during demodulation, Therefore, it is believed that there are few embodiments of the double father signal. The King's code is world-famous for providing a set of approximately orthogonal telecommunications signals that are easy to implement, and since the discovery of the aforementioned method, the 'Kin' code has been widely used in direct-sequence spread-spectrum modems. Another well-known explanation is pages 107 to 109 of the proceedings of the twenty-sixth "Communications, Control, and Computer Symposium" held in Aller ton in 988, by stark ) And Woerner's "lattice coding technology is applied to direct sequential compound access spread spectrum communication π. The aforementioned method is to use an extra bit (even if this extra bit can only Produces the same effect), and phase inversion based on any member of the family of the Orthogonal King ’s code can be applied to implement this biorthogonal combination. Moreover, in the conventional technique, the first bit is used to transmit data, The sequence of variable-rate CDMA and networks can be generated from pages 164 to 175 of the minutes of the second "Radio Seminar Annual Meeting" of 994, proposed by Bart Rice.

This special-purpose integrated circuit also provides the interface between radio waves and modulators and the central processing unit. Generally speaking, the reception of the Tessen Road is only after receiving the pole one. From the intermediate frequency (n IF ") signals, it is necessary to use a cosine reference curve to provide the reference comparison of the aforementioned intermediate signals, and the subsequent signals. Reverse operation. The signal processed in this way will have sharper contrast than the signal of the conventional inverse sampling technology, and the conventional technology requires a reverse inverse comparison of the samples in two reference numbers such as a cosine curve and a sine curve. Correct. ^ Please refer to the circuit diagram shown in Figure 23. The part shown in this circuit diagram is: the reference circuit 500 that supplies the cosine curve. The composition of this part of the circuit is described below. The main components of circuit 500 include: 2D flip-flops 502 and 514 with a low reset and positive edge trigger for each action, a drive device 504 with complement output, a mutex or gate 506, and a Mutually exclusive OR gate 508. At the same time, this circuit also includes two two-to-one multiplexers 51 and 512, and 2D flip-flops 516 and 518 with low reset and negative edge trigger. In addition, there are two following devices 520 and 522 and two mutually exclusive OR gates 524 and 526. As shown in FIG. 23, the input intermediate frequency signal enters the flip-flop 502 through the line 28, and the output of the flip-flop 502 is connected to the mutex or closed 506 and -mutex non-or_8 Input of the mutex or gate 5 () 6

Page 118 475321 V. Description of the invention (116) 1 connection; Recognition-input to one-to-one multiplexer 510, meanwhile, the output of mutually exclusive non-biting gate 5.8 is connected to two-to-one multiplexer 512 Input, the output of two two'n is connected to the follower device 522 to maintain the flip-flop, and the output of the flip-flop 518 is connected to the follow-up device 52. The output of the mutex NOR gate 508 is connected to the two-to-one multiplexer input, and the output of the multiplexer 512 is connected to the flip-flop 51 / and the mutex gate 524 and the NOR gate 526. The outputs of the followers 52 and 522 provide the in-phase signal output of the two ζ components, but the mutually exclusive OR gate 524, 526 = the two-component inverse signal output ..., using the aforementioned circuit, "疋 only needs a cosine The reference curve can flip the entire signal into an inverted signal. Compared with more complex conventional processing methods, two reference signals, such as a cosine curve and a "sine curve," are required to reverse the phase of the alternating samples. The effect, another method at 3 o'clock-the advantage is that you can use a processor with low computing power to process the signal. Please refer to Figures 24 to 27, which illustrate the sampling and sequencing circuit components. These circuits Most of the components are implemented using conventional parts, and the sequencing technique also comes from the common inverse (Q) sampling method. In any case, the circuit of the present invention has eliminated that the conventional circuit must combine the reference signal mixed with two sine curves and Disadvantages of the generator of the inverting signal (in the present invention, only two inverters are needed to replace the conventional circuit described above). The Mingzhi circuit will not have the error of channel mis-combination. The special circuit components used in Figure 24 and Factory 27 include: the ability to adjust the in-phase (I) and reverse-phase (Q) signals without phase alignment signals ^ 路 ^ Relative to all other radio communication systems in order to ensure the use of communications

P.119 475321 V.

The function of the receiver 'and the electrical capacity of the middle can be mistaken. Simultaneous detection is used as a synchronous transmission application with few error detection signals. The present invention requires the use of a phase alignment signal as the signal in the signal. The circuit element of Figure 24-27 is managed to maintain the appropriate frequency bandwidth. ; That is, even if the number, you can still establish and maintain communication connections in place. In short, except in a conventional wireless communication system, the preferred embodiment of the present invention does not require these components. The circuit component 5 2 8 includes ... 4 with low reset and roundness, and 538. ;: As shown in Figure ^ and:: 4-bit flip-flops 54 and 542 with low reset, and 8-bit offset register 548 with low reset. The circuit component 528 also provides a function that helps to mix signals. At the same time, this official capability also includes current processing. This is because the reference bit can have a strong current bit to follow the circuit replaced by t. From time to time, the subsequent signal processing will develop a chip = alum number, and a debug signal for signal strength evaluation = a predicate signal for the loop, where the chip will track the same frequency as the chip, but this The occurrence date of the circuit i 528 also starts the reference signals of these circuits by signal frequency and chip transmission. Because of the benefits of two = some functions' and these functions ,,,,,,,, and systems to implement the fundamental frequency transmission and connection 475321-V. Description of the invention (118) Please refer to Figure 25, circuit components 5 5 0 include · Two 4 X 4-bit multipliers 551 and 552; two 8-bit absolute value calculators 553 and 554; two 4-bit binary full adders with fast transfer capabilities 5 5 5 and 5 5 6; and a 1-bit binary full adder 5 5 7.

The adjustment rate at the signal is the phase of the clock signal pattern that has been ranked by the general phase adjustment action. The phase of the spatial reference phase is used in the synchronous engineering step in this disclosure to calculate the continuous frequency. The reason for maintaining the same establishment is so that the previously required if $ is completed in the circuit of Figures 23-27, and each data frame / each signal generates a bit (N) adjustment rate with a phase difference of 90 degrees, At the same time, there is ample frequency offset, which is due to the Doppler / alignment to the subsequent processing procedures, these procedures and the demodulation. As a result, these signals can be transmitted without hesitation. So it is clear for the subsequent processing procedure = it is necessary. In short, the rapid peer-to-peer project needs s γ ^ to be designed in a time-domain data frame for a short period of time, compared with what is required in conventional radio communication systems and uses fewer microprocessor resources to complete

In this regard, the development of the aforementioned two types of gate signals is based on the fact that each of these signals determines the size and number of the received signals for confrontation and comparison. The feature point of the aforementioned sample in the marked range is helpful for inventing this feature point in the interactive process. It can provide the total number of square waves of the telecommunication signal. The information of the original standard anti-phase signal will be conflicted by the information provided by the channel. The power management factor of each signal is described. The circuit component of the present invention is shown in the standby frequency and gate function of the frequency adjustment signal. It also uses standby and the corresponding distribution of the in-phase and anti-phase electrical signals to participate in an interactive process, so that the purpose of the Jin's interactive process with each reference is to determine whether it has been transmitted. Because of the strong signal retention mentioned above, this one has a better performance than the known one in the two channels. To do this, the receiving device compares the existing ones.
