The control logic unit 111 controls all internal blocks of the PABS control module, analyzes the HCC and PCC received from the outside, and determines the operation for each state of the wireless relay terminal device. In addition, the control logic unit 111 reads or writes ROM address and parameter information for generating opcodes and parameters of HCC and PCC. Generates.

The PCC ROM 112 stores an opcode and a parameter table for generating a PCC. The PCC ROM 112 receives an address from the control logic unit 111 and receives an opcode of the PCC. The PCC packet register 120 passes the parameters to the PCC parameter mux 116, respectively.

The HCC-PCC parameter converter 115 is a block for parameter conversion in order to transfer HCC to PCC or PCC to HCC and store the data in the SRAM 114. That is, the PCC parameter received from the PCC parameter demux 118 is converted into an HCC parameter and transferred to the HCC parameter mux 117, and the HCC parameter received from the HCC parameter demux 119 is converted into a PCC parameter to PCC. It passes to the parameter mux 116.

The PCC parameter mux 116 stores the ACL / SCO data from the HCC parameter demux 119 and the parameters input from the HCC-PCC parameter converter 115 and the parameters stored from the SRAM 114 and the PCC ROM 112, respectively. Is provided, and selects only one data currently required by the control of the control logic unit 111 and provides it to the PCC packet register 120.

The data is provided, and only one data currently required by the control of the control logic unit 111 is selected and provided to the HCC packet register 121.

The PCC parameter demux 118 is a PCC command parameter and the HCC parameter mux 117 to be sent from the PCC packet register 120 to the HCC-PCC parameter converter 115 by a control signal from the control logic unit 111. Select one of the ACL / SCO data to send to.

The HCC parameter demux 119 transmits the HCC command parameter and the PCC parameter mux 116 from the HCC packet register 121 to the HCC-PCC parameter converter 115 by a control signal from the control logic unit 111. Select one of the ACL / SCO data to send to.

The PCC packet register 120 stores the PCC command opcode received from the PCC ROM 112 and the PCC parameter received from the PCC parameter mux 116 in the form of one PCC packet, and then stores the stored PCC packet. To the PCC packet processing unit 122 or temporarily store the PCC packet received from the PCC packet processing unit 122 to transmit the opcode to the control logic unit 111, the parameter to the PCC parameter demux 118 Send each one.

The HCC packet processing unit 123 receives the HCC packet from the HCC packet register 121, attaches a packet type indication header, synchronizes it, and passes the HCC packet to the UART interface module 150 through the HCC UART controller 125. The reverse process is performed, and static flow control is possible through an internal packet buffer.

Here, the HCC packet processor 123 does not perform synchronization, multiplexing, and demultiplexing as compared with the PCC packet processor 122, except that there is a packet type indication block.

The PCC UART controller 124 is for a wired interface, and drives the UART transmission / reception module (not shown) of the wired interface module 130. Therefore, the PCC is transmitted to the wireless relay terminal device in another region through the wired interface driver RS485 via the PCC UART controller 124 and the external UART transmit / receive module.

The HCC UART controller 125 is for communication with the wireless transmission / reception module 170 and communicates with the UART port of the wireless transmission / reception module 170.

The PCM driver 126 is an interface driver for exchanging PCM signals through the PCM port of the wireless transmission / reception module 170. The microprocessor interface 127 is an interface block for communicating with the UART port of the microprocessor for performing additional functions, which is not easy to perform in various WLAN terminals.

Hereinafter, a data communication method using the wireless relay terminal device will be described in detail with reference to FIGS.

First, the first wireless relay terminal 100 configures a bus network through a wired interface, and delivers a token according to the order of a hardware identification number (HID) to daisy-chain the daisy chain to use the bus. Bus Arbitration is performed through Chain. Initially, only the first wireless relay terminal 100 bus- arbitrated through the daisy chain may use a bus network.

That is, as shown in Figure 5, the daisy chain is implemented using a header (header), the first wireless relay terminal 100 is a header (Header) for the daisy chain in the PABS PCC packet processing unit 122 Generate a preamble header for synchronization. When the first wireless relay terminal 100 does not need a bus, the token is transmitted to another wireless relay terminal through the PCC UART controller 124 and the wired interface module 130. In this case, the other wireless relay terminal device accepts the token, compares it with its own HID, and determines whether the token is accepted, and this process is continuously performed.

Therefore, after receiving the PCC, the second wireless relay terminal device 200 and the third wireless relay terminal device 300 bring the PCC to the PCC packet processing unit 122 by the reverse process, and then the PCC opcode and the HID. After determining the token authentication through the control logic unit, the bus arbitration is performed again. The above process is continuously performed while the first wireless relay terminal device 100, the second wireless relay terminal device 200, and the third wireless relay terminal device 300 do not communicate.

Secondly, each of the first wireless relay terminal device 100, the second wireless relay terminal device 200, and the third wireless relay terminal device 300 is connected to a wireless LAN terminal through a periodic inquiry. Collect information. That is, as shown in FIG. 7, the first wireless relay terminal device 100 may inquiry and then device local name through wireless communication with the WLAN A terminal 101 and the WLAN B terminal 102. (Device Local Name) is requested to receive the corresponding information, and the second wireless relay terminal device 200 is inquiry (inquiry) and through the wireless communication with the WLAN C terminal 201 and WLAN D terminal 202 Subsequently, a device local name is requested and the corresponding information is received, and the third wireless relay terminal device 300 inquires through a wireless communication with the wireless LAN E terminal 301 and subsequently the device local name. Request (Device Local Name) to receive the relevant information.

That is, each wireless relay terminal device collects and stores a device local name by sending HCC remote name request (HCC_Remote_Name_Request) information back to the collected device after the inquiry.

Here, look at the process of collecting the information of the surrounding wireless LAN terminal in detail as follows.

First, in FIG. 5, when the control logic unit 111 generates a ROM address in which an opcode and a parameter of an HCC query (HCC_Inquiry) is stored and transmits the ROM address to the HCC ROM 113, the HCC ROM 113 is transmitted. The opcode is directly passed to the HCC packet register 121 via the HCC parameter mux 117. Then, the HCC packet register 121 passes the opcode and parameters to the HCC packet processing unit 123 in the form of an HCC packet. The HCC packet processing unit 123 receives this, stores it in the packet buffer for a while, and attaches a packet type indication header to the HCC UART controller 125 and the UART interface module 150. Transfer to the wireless transmission and reception module 170.

On the other hand, the information of the neighboring wireless LAN terminal of the first wireless relay terminal device 100 collected through Inquiry, that is, the information of the WLAN A terminal 101 and the WLAN B terminal 102 is once HCC query When the result event (HCC_Inquiry_result_Event) comes up from the radio transceiver module 170 to the HCC packet processing unit 123 through the above reverse process, the opcode is transmitted to the control logic unit 111, the control logic unit ( 111 determines that the HCC has terminal information through the transmitted opcode, and converts the parameter inputted to the HCC parameter demux 119 through the HCC packet register 121 to the HCC-PCC parameter converter 115. After changing the parameter field format in the) SRAM 114 is stored as terminal information.

At this time, the control logic unit 111 stores the address area where the terminal information is stored in the SRAM 114 again using BD_ADDR as an index. In this case, the storage in the SRAM 114 is intended to be used again in a rotational inquiry, which will be described later. Meanwhile, the local device name also receives and stores information through the same process as the query.

Third, the first wireless relay terminal 100 transmits information (BD_ADDR, Device Class, Device Name, Page scan mode) of the wireless LAN terminals 101 and 102 obtained through the query through the PCC of the bus network. It exchanges and stores the relay terminal device 200 and the third wireless relay terminal device 300.

That is, as shown in FIG. 8, device information of the WLAN A terminal 101 and the WLAN B terminal 102 stored in the SRAM 114 of the first wireless relay terminal device 100 may be the first. When the wireless relay terminal device 100 is granted through bus arbitration, the wireless relay terminal device 100 is transferred to the second wireless relay terminal device 200 and the third wireless relay terminal device 300.

In this case, when the control logic unit 111 of FIG. 5 passes the address to the PCC ROM 112, the PCC ROM 112 delivers an opcode to the PCC packet register 120, and the device information of the terminal is The SRAM 114 is transmitted to the PCC packet register 120 via the PCC parameter mux 116, and is made into a PCC packet together with an opcode, and is then transmitted to the PCC packet processing unit 122.

Then, the PCC packet processor 122 attaches a preamble header for synchronization to the received PCC packet and transfers it to the PCC UART controller 124 to transmit the second PC in another region through the wired interface module 130. The transmission to the wireless relay terminal device 200 and the third wireless relay terminal device 300 is performed, and the receiving process is the same as the reverse process.

Fourth, the first wireless relay terminal device 100, the second wireless relay terminal device 200, and the third wireless relay terminal device 300 respectively rotate queries and page scans while rotating device information stored therein. (Inquiry / Page Scan), wherein any one of the first wireless relay terminal device 100, the second wireless relay terminal device 200, and the third wireless relay terminal device 300 is a wireless LAN terminal. The operation is repeated until the page signal is received. Herein, the above operation is referred to as a rotational inquiry / page scan process.

Here, the detailed description will be made based on the first wireless relay terminal device 100.

As shown in FIG. 9, the control logic unit 111 of the first wireless relay terminal device 100 is located in other regions stored in the SRAM 114 (Wireless LAN C terminal 201, Wireless LAN D). A cyclic query / page scan is performed through the BD_ADDR of the terminal 202 and the wireless LAN E terminal 301. At this time, the opcode is repeated in order by the address transmitted from the control logic unit 111 to the HCC ROM 113, and each HCC command parameter is stored using the corresponding device information stored in the SRAM 114. Again, each time the device's BD_ADDR changes.

Fifth, according to an embodiment by the rotational inquiry / page scan operation of the first wireless relay terminal device 100, the WLAN A terminal 101 is shown in FIG. The first wireless relay terminal 100 is recognized as a wireless LAN terminal in another region.

Sixth, as shown in Figure 11, the user of the wireless LAN A terminal 101 is the device information collected through the first wireless relay terminal device 100 (Wireless LAN C terminal 201, wireless LAN D terminal 202 and the wireless LAN E terminal 301 may be identified in the same manner as the information of the surrounding wireless LAN B terminal 102, and the wireless LAN terminal information to be dually connected may be selected.

Seventh, as shown in FIG. 12, the first wireless relay terminal device 101 performs a page by loading information of the wireless LAN C terminal 201 selected by the user as an embodiment. At this time, the page is repeated several times for a predetermined time by the connection request command.

Eighth process, as shown in Figure 13, the first wireless relay terminal 100 is connected to the WLAN A terminal 101 during the rotational inquiry / page scan (Rotational Inquiry / Page Scan) operation (Connection) Recognizes a page signal transmitted from the WLAN A terminal 101 when performing a scan operation on a device to be connected.

In the ninth process, as shown in FIG. 14, when the first wireless relay terminal device 100 recognizes a page signal, it waits during a daisy chain operation and wirelessly when the bus is granted by arbitration. The second wireless relay terminal device 200 and the third wireless relay terminal device generate a PCC connection request signal generated by the first wireless relay terminal device 100 having the BD_ADDR information of the LAN C terminal 201. Send to 300.

That is, the HCC connection request event (HCC Connection_Request_Event) transmits the HCC packet from the wireless transmission / reception module 170 of the first wireless relay terminal device 100 to the HCC packet processing unit 123 through the UART interface module 150, The HCC packet processor 123 transfers the HCC packet from which the header is removed to the HCC packet register 121. Then, the HCC packet register 121 transfers the HCC opcode to the control logic unit 111.

Accordingly, the control logic unit 111 determines that the HCC connection request event (HCC_Connection_Request_Event) is an opcode received from the HCC packet register 121, and determines the address for the PCC connection request (PCC_Connection_Request) from the PCC ROM 112. To pass.

Then, the opcode of the PCC connection request (PCC_Connection_Request) stored in the PCC ROM 112 is transferred to the PCC packet register 120, and the current cyclic query / page is controlled by the control logic unit 111. The BD_ADDR of the device corresponding to the scan (Rotational Inquiry / Page Scan) section and the device information are transferred from the SRAM 114 to the PCC packet register 120 via the PCC parameter mux 116.

In this case, the PCC packet register 120 assembles a PCC connection request command packet using an opcode received from the PCC ROM 112 and a parameter received from the PCC parameter mux 116. after. After the assembled PCC connection request command packet is granted to the PCC packet processing unit 122, the PCC UART controller 124, and the wired interface module 130 through bus arbitration, a second wireless relay is performed. It transmits to the terminal device 200 and the third wireless relay terminal device 300.

In the tenth process, as shown in FIG. 15, the second wireless relay terminal device 200 and the third wireless relay terminal device 300 that have received the PCC_Connection request command packet through a wire are respectively. The connection request for the BD_ADDR corresponding to the corresponding WLAN terminal is executed.

That is, the second wireless relay terminal device 200 and the third wireless relay terminal device 300 that have received the PCC connection request (PCC_Connection_Request) from the first wireless relay terminal device 100 through each HCC-PCC parameter converter. After checking the BD_ADDR field, it compares with the BD_ADDR of the wireless LAN terminals located in the local area and ignores it if it is not the same. If it is the same, an address for the HCC connection (HCC_Connection) is generated and sent to the HCC ROM.

In the embodiment of the present invention, since the wireless LAN C terminal 201 requesting the connection is connected to the second wireless relay terminal device 200, the HCC ROM of the second wireless relay terminal device 200 is connected to the HCC connection ( After generating the opcode of HCC_Connection), the HCC-PCC parameter converter converts the received device parameter into the field format of the HCC connection (HCC_Connection) and sends it to the HCC packet register via the HCC parameter mux. Subsequently, the second wireless relay terminal device 200 generates an HCC and transmits the UART interface module to the wireless transmit / receive module in the same manner as the second process of the first wireless relay terminal device 100 described above.

In the eleventh process, as shown in FIG. 16, when the second wireless relay terminal device 200 is connected to the WLAN C terminal 201 to be connected, the second wireless relay terminal device ( 200 is authorized to use the bus network as a slave. Meanwhile, the third wireless relay terminal device 300 which is not connected is not granted and only receives the PCC through the bus network and does not send the PCC.

Therefore, when the connection with the corresponding WLAN C terminal 201 is smoothly completed by the HCC connection (HCC_Connection) command transmitted to the wireless transmission / reception module in the tenth process, the HCC connection completion event (HCC_Connection_Complete Event) is performed. Is transmitted to the HCC packet processing unit. At this time, when the control logic unit 111 of the second wireless relay terminal device 200 confirms this through an opcode, it first through its PCC packet processing unit 122 performs its own bus daisy chain. After authorizing the state to the slave (Slave authorized), and generates a PCC connection acceptance (PCC_Connection_Accept) and transmits to the first wireless relay terminal device 100, the bus is approved to the master through the wired interface module. At this time, the process of creating the PCC is the same as the third process of the first wireless relay terminal 100 described above.

The twelfth process, as shown in FIG. 17, is a wireless LAN A terminal 101 and a first wireless relay terminal device 100, and a second wireless relay terminal device 200 and a wireless LAN C terminal 201. When the connection is completed, the WLAN A terminal 101 and the WLAN C terminal 201 communicate with each other via the first and second wireless relay terminal devices 200 through the first wireless relay terminal device 100. do.

That is, the first wireless relay terminal device 100 which has received the PCC connection acceptance (PCC_Connection_accept) from the second wireless relay terminal device 200 authorized as a slave through the wired interface is then the second wireless relay terminal device 200. It communicates through PCC packet with Half Duplexing method. Therefore, after the first wireless relay terminal device 100 and the second wireless relay terminal device 200 are connected, the data packet is transmitted from the HCC packet processor 123 of the first wireless relay terminal device 100 to the PCC packet processor 122. Therefore, the PCC packet processing unit 122 is directly transmitted to the HCC packet processing unit 123 to the second wireless relay terminal device.

The ACL data packet is delivered to the UART interface module 130, the HCC packet processing unit 123, the HCC packet register 121, the PCC parameter mux 116, and the PCC packet register 120, assembled into PCC packets, and then wired interface. The module 130 is transmitted to the second wireless relay terminal device 200.

In the case of the SCO data packet, the PCM signal is received through the PCM driver 126 and then transmitted by the PCC packet processor 122 through the wired interface module 130. The transmitted data packet is demultiplexed by the PCC packet processing unit 122 via the wired interface module 130 and the PCC UART controller 124, and then the PCM driver 126 or the PCC packet register 120 and the HCC parameter. The mux 117, the HCC packet register 121, the HCC packet processing unit 123, and the UART interface module 150 are transmitted to the wireless transmission / reception module 170.

In the thirteenth process, as shown in FIG. 18, when the connection between the WLAN A terminal 101 and the WLAN C terminal 201 is completed, the bus granted first wireless relay terminal device 100 is completed. ) And the second wireless relay terminal 200 only exchange data and use a bus network.

The third wireless relay terminal device 300 that is not granted receives the PCC exchanged between the first wireless relay terminal device 100 and the second wireless relay terminal device 200 that are granted. Bus network not available.

Instead, after receiving the PCC connection acceptance (PCC_Connection_accept) from the second wireless relay terminal device 200, the disapproved third wireless relay terminal device 300 performs a periodic inquiry (Periodic Inquiry) while the connection is continued. Update the information of the connected WLAN terminals in the area. At this time, periodic inquiry (Periodic Inquiry) and information update of the wireless LAN terminals are the same as the second process described above.

A fourteenth process is flow control of the first wireless relay terminal device 100. In the network of the wireless relay terminal device, a link manager is responsible for the wireless section and a PABS is responsible for the wired section.

Therefore, the first wireless relay terminal device 100 adjusts the signal flow statically by adjusting the buffer size and the data processing rate, and between the wireless transmission / reception module 170 and the PABS control module 110. The flow is dynamically controlled by controlling the RTS / CTS bits between the HCC, UART, and wired interface modules.

In a fifteenth process, as shown in FIG. 19, the wireless LAN A terminal 101 communicating with the first wireless relay terminal device 100 determines the connection mode during connection between the wireless relay terminal devices. When the mode is changed to the park mode or the hold mode, the first wireless relay terminal device 100 and the second wireless relay terminal device 200 are connected through a wire without using the entire wireless relay terminal system. In this case, the other WLAN terminal, that is, the WLAN C terminal 201, does not use the wireless relay system. Therefore, the first wireless relay terminal 100 participating in the current connection is automatically terminated if the exit mode does not become within a certain time after the mode change.

That is, the PABS control module 110 receives the mode conversion event through the PCC packet processing unit 122 or the HCC packet processing unit 123 during the connection, or the storage packet counted by the HCC receiving buffer (not shown) of the HCC packet processing unit. The number of times of connection loss is not increased (connection lost state) by using the internal counter in the control logic unit 111 and after a predetermined time has elapsed, and automatically generates an HCC address for HCC disconnection (HCC_Disconnection). The operation is the same as the HCC instruction generation and delivery process mentioned in the second process described above.

In the sixteenth process, as shown in FIG. 20, when a disconnection event occurs from the WLAN C terminal 210 during connection, the second wireless relay terminal device 200 sends a PCC connection termination command. Is transmitted to the first wireless relay terminal device 100 and the third wireless relay terminal device 300 through a wire, and the connection of the current WLAN C terminal 201 is terminated.

At this time, the approved first wireless relay terminal device 100 transmits the PCC connection termination (PCC_Disconnection) to the second wireless relay terminal device 200 approved as the slave to which the current connection is made, thereby simultaneously terminating the connection.

Accordingly, both the first wireless relay terminal device 100 and the third wireless relay terminal device 300 that have confirmed the PCC connection termination command become Not Granted in bus arbitration, and are the first wireless relay terminal device that were masters. 100 again passes the token on the daisy chain to the next second wireless relay terminal device 200 and the third wireless relay terminal device 300.

Here, the connection termination event may occur in various cases. That is, the wireless LAN terminals may normally generate through the transmission of the HCC command and the PCC command, and the wireless LAN terminal may be over the communication distance, the park mode, the hold mode, or the switch. It is possible to automatically terminate the inside of the wireless relay terminal apparatus by connection lost due to timeout such as a sniff mode.

   In addition, the third wireless relay terminal device 300 which is in the disapproved state is another wireless relay terminal device, that is, the first wireless relay terminal device 100 and the first when the bus information is approved by the third wireless relay terminal device 300. 2 is transmitted to the wireless relay terminal device 200, respectively. At this time, the operation of the third wireless relay terminal device 300 is the same as the thirteenth process described above.

On the other hand, the present invention has been described the operation of the wired UART interface module and the wireless transmission and reception module in a single configuration, respectively, preferably can be implemented using a plurality, the embodiment of the technical operation based on the two configuration This will be described with reference to FIGS. 21A through 21D.

That is, referring to FIG. 4, two wired interface modules performing the same function are connected in parallel to the PABS control module 110, and two wireless transmission / receiver modules performing the same function are controlled by the PABS through their respective UART interface modules. Connect in parallel to the module. At this time, the PABS control module simultaneously controls the parallel devices inside the control unit.

Here, in order to relay the plurality of WLAN terminals, the PABS performs a cyclical query and page scan. For this purpose, a reset time is required whenever the PABS is changed to the WLAN terminal information to be relayed.

21A shows that when implemented through one module, an empty interval occurs every time for each recursive query and page scan time.

That is, in one embodiment, the time required for the recursive query and page scan time is 2.56 seconds, and the empty interval due to warm reset takes about 1 second.

Accordingly, in order to avoid overlapping empty intervals between the recursive query and page scan times using two modules, as shown in FIG. 21B, the other module performs a recursive query and page scan operation even at the empty interval time of one module. This can be done to eliminate free time due to reset. In other words, by using two or more wireless transmission modules, the overall cyclical query and page scan time can be reduced. As shown in FIG. 21C, when four wireless LAN terminals exist in the surrounding area, the cyclical query and page scan time is reduced. If a single module takes 14.24 seconds, but using two wireless transmit / receive modules, the time can be reduced by 60% to 8.9 seconds as shown in FIG. 21D.

In short, using more than one module can save more time.

In addition, if one module is used to maintain a connection after a connection is made, the other module can be used to search for peripherals, allowing a quick update of changes in WLAN terminals around the PABS even while connected.

In addition, when the above-described two modules are simultaneously connected, the first wireless relay terminal device 100 and the wireless LAN terminals 101 and 102 have two communication channels.

Accordingly, as shown in FIG. 22, when a predetermined amount of data is transmitted, the transmission time can be reduced by the number N of channels by dividing the number of N channels per N wireless transceiver modules. At this time, the data is divided into HCC packets and sent or received as HCC packets, and the division and assembly are performed by the HCC packet processing unit 123 under the control of the control logic unit 111. In this case, regardless of the speed limited by the WLAN terminal, the user can adjust the data transmission rate appropriately for the application.

That is, when the HCC packet processing unit 123 makes the HCC packet, the HCC packet is alternately transmitted to the buffer D3 alternately with the connection handle bit of the data packet, and the packet temporarily stored in the buffer D3 is mux. Through the D1, the first and second UART controllers 125A and 125b are alternately sent.

In addition, the packets are alternately received through the demux D2, and all of these operations are performed at a speed (9600-234 kbps) of the UART interface module 150 and a processing speed (13M-20 MHz) of the PABS control module 110. The data processing (13M-20MHz) inside the WLAN terminal is much faster than the data transmission rate (1M bps) of the wireless communication channel.
