The protocol of " (d) " is a protocol for burst mode, which is used when a plurality of data is transmitted in one data packet at a time.

Although an example of the protocol structure of the data packet is illustrated in FIG. 4, the protocol structure of the data packet transmitted or received by the communication assistant 100 may be variously changed as necessary.

Referring back to FIG. 2, the filtering module 303 examines the command information CMD included in the received data packet RDPKT1 received from the first serialization module 302, and processes the received data packet RDPKT1. Judge. According to the determination result, the filtering module 303 removes the received data packet RDPKT1 not to be processed and outputs only the received data packet RDPKT1 to be processed to the main processing module 304.

The main processing module 304 receives, in order to update the setting information SETIF or the status indication information STPIF, according to the command information CMD included in the received data packet RDPKT1 received from the filtering module 303. Based on the data packet RDPKT1, an operation for outputting the setting data SETDAT or the status indication data STPDAT or for transmitting the received data packet RDPKT1 to the cellular phone 201 is executed.

The main processing module 304 displays setting information SETIF or information about the mobile phone HPIF or status according to the command information CMD included in the received data packet RDPKT2 received from the second serialization module 309. To update the information STPIF, based on the received data packet RDPKT2, the setting data SETDAT or mobile phone data HPDAT or status indication data STPDAT are output or the received data packet RDPKT2 is USN. Output to USN data transmission module 310 for transmission to at least one communication node included in 202.

The main processing module 304 stores the received data packet RDPKT1 or RDPKT2 in a priority queue according to the priority information PRI (see FIG. 4) included in the received data packet RDPKT1 or RDPKT2. The command information CMD included in the received data packet RDPKT1 or RDPKT2 is examined according to the priority. In addition, when there are a plurality of received data packets RDPKT1 or RDPKT2 having the same priority, the main processing module 304 checks the command information CMD included in the received data packets RDPKT1 or RDPKT2 according to the stored order. do.

Optionally, the main processing module 304 stores consecutively received data packets RDPKT1 or RDPKT2 received in the order in which they are received, and according to the stored order, the command information (RDPKT1 or RDPKT2) contained in the received data packets RDPKT1 or RDPKT2. CMD).

The internal state machine 305 stores the setting information SETIF and the information about the mobile phone HPIF. The internal state machine 305 updates the setting information SETIF based on the setting data SETDAT received from the main processing module 304.

The display control module 306 stores the status display information STPIF to be output to the status display unit 160 based on the status display data STPDAT. The display control module 306 updates the status display information STPIF based on the status display data STPDAT received from the main processing module 304. The display control module 306 stores the alarm data ARDAT received from the main processing module 304. Based on the status display data STPDAT stored in the display control module 306, the status display unit 160 visually or audibly represents the operation state of the communication assistance device 100. In addition, the state display unit 160 generates a visual alert or an audio alert based on the alert data ARDAT stored in the display control module 306.

The phone data transmission module 307 divides the received data packet RDPKT1 received from the main processing module 304 into transmission byte stream data TBST2 and outputs it to the communication interface unit 140.

Here, the reason why the transmission / reception data between the wireless communication unit 120 and the communication auxiliary device 100 or the transmission / reception data between the mobile phone 201 and the communication auxiliary device 100 is in the form of byte stream data divided by the set byte unit is This is to achieve the optimization of communication.

The phone data receiving module 308 receives the received byte stream data RBST2 in a predetermined byte unit from the mobile phone 201 through the communication interface 140. The second serialization module 309 generates the received data packet RDPKT2 based on the received byte stream data RBST2 received from the phone data receiving module 308 and outputs it to the main processing module 304. The operation of the second serialization module 309 is similar to that of the first serialization module 302 described above.

The USN data transmission module 310 divides the received data packet RDPKT2 received from the main processing module 304 into transmission byte stream data TBST1 and outputs the received data packet RDPKT2 to the wireless communication unit 120.

On the other hand, in the internal memory (not shown) of the cellular phone 201, as shown in FIG. 1, communication support programs PGM1 to PGMK (K is an integer) for communication with the communication assistance apparatus 100 are stored. The communication support programs PGM1 to PGMK are programs for communicating with communication nodes included in a plurality of USNs that provide different services, respectively.

For example, the communication support program PGM1 is a program for communication with a communication node included in a USN providing attendance confirmation service, and the communication support program PGM2 is a communication node included in a USN providing fire monitoring service. It may be a program for communication with. In addition, the communication support program PGM3 may be a program for communication with a communication node included in a USN providing a security service.

Therefore, the user can execute one of the communication support programs PGM1 to PGMK stored in one mobile phone 201 to receive a desired service. In addition, when a part of the service is changed, the user may be provided with the changed service by upgrading only a communication support program corresponding to the service stored in the mobile phone 201 without replacing hardware.

Referring to FIG. 3, the configuration of the communication support programs PGM1 to PGMK will be briefly described as follows. Since the configurations of the communication support programs PGM1 to PGMK are similar to each other, the configuration of the communication support program PGM1 will be described with reference to FIG.

The communication support program PGM1 includes a serialization module 321, a main processing module 322, an internal state machine 323, a display control module 324, and a key input processing module 325. The serialization module 321 and the main processing module 322 form a data processing thread, and the display control module 324 and the key input processing module 325 form a user interface thread.

The serialization module 321 receives the transmission byte stream data TBST2 received from the communication interface unit 140 of the communication auxiliary device 100 in a set byte unit through the data terminal of the socket 210. The serialization module 321 obtains the transmission byte stream data TBST2 from the communication assistant 100 using a polling method or an interrupt method similar to the USN data receiving module 301.

The serialization module 321 generates the reception data packet RDPKT3 based on the transmission byte stream data TBST2. Here, the serialization module 321 plays a role similar to that of the USN data receiving module 301 and the first serialization module 302 described above with reference to FIG. 2. In the case of the mobile phone 201, since the access service routine (ISR) is not accessible, the serialization module 321 includes both the functions of the USN data receiving module 301 and the functions of the first serialization module 302.

The main processing module 322 is stored in the internal state machine 323 based on the received data packet RDPKT3 according to the command information CMD contained in the received data packet RDPKT3 received from the serialization module 321. The internal state information HSPTIF of the mobile phone 201 is updated or a transmission data packet TDPKT1 is generated based on the internal state information HSPTIF of the mobile phone 201.

The main processing module 322 updates the internal state information HSPTIF of the mobile phone 201 stored in the internal state machine 323 based on the received data packet RDPKT3 or the mobile phone stored in the internal state machine 323. When retrieving internal state information (HSPTIF) of 201, an application programming interface (API) function is used.

The main processing module 322 divides the transmission data packet TDPKT1 into the reception byte stream data RBST2 and transmits it to the communication interface 140. For example, when the command information CMD included in the received data packet RDPKT3 includes a cellular phone information request command, the main processing module 322 converts the transmitted data packet TDPKT1 into the received byte stream data RBST2. The data is divided and transmitted to the communication interface unit 140.

The internal state machine 323 stores internal state information (HSPTIF) of the mobile phone. The display control module 324 displays display information DISIF to be displayed on a display screen (not shown) of the mobile phone 201 based on the internal state information HSPTIF of the mobile phone 201 stored in the internal state machine 323. Occurs. The key input processing module 325 is based on an input data signal INDAT received from an input unit (not shown) of the mobile phone 201 in response to a user's input, so as to store the inside of the mobile phone 201 stored in the internal state machine 323. Update the status information (HSPTIF).

The internal status information HSPTIF indicates identification information (ie, identification) of the mobile phone 201, owner information of the mobile phone 201, location information of the mobile phone 201, and whether the communication assistant 100 is connected. Flag information FL1, security information, list information of devices controllable in the mobile phone 201, and list information of programs executable in the mobile phone 201. The security information includes information on the location accessible by the mobile phone 201.

FIG. 5 is a flowchart illustrating an example of an execution process 1100 of a communication support program of the communication assistant device illustrated in FIG. 2, when the communication assistant device 100 receives byte stream data from a communication node of the USN 202. Indicates the execution of the communication support program.

When the plug 101 of the communication assistant 100 is inserted into the socket 210 of the mobile phone 201, the main controller 130 executes a communication support program (TPGM) to confirm the connection of the mobile phone (step 1101). ).

Referring to FIG. 6, a process of executing the communication support program TPGM in step 1101 will be described in more detail as follows. Initially, initialization of internal registers 132 and variables is performed (step 1121). The main processing module 304 transmits the transmission data packet TDPKT2 including the information about the cellular phone (HPIF) to the cellular phone 201 via the phone data transmission module 307, thereby transmitting information about the cellular phone (HPIF). Request (step 1122). The phone data transmission module 307 divides the transmission data packet TDPKT2 by the set byte unit and transmits the transmission byte stream data TBST3 to the mobile phone 201.

Thereafter, via the phone data receiving module 308 and the second serialization module 309, the main processing module 304 receives the received data packet RDPKT4 including the information HPIF about the mobile phone from the mobile phone 201. This is received (step 1123).

The main processing module 304 compares the received information about the cellular phone (HPIF) with the previously stored cellular phone information (HPIF ') (step 1124). As a result of the comparison, the main processing module 304 determines whether or not the received information about the cellular phone (HPIF) and the previously stored cellular phone information (HPIF ') match each other (step 1125). The main processing module 304 maintains the mobile phone information HPIF 'stored in the internal state machine 305 as it is when the received information about the mobile phone (HPIF) and the prestored mobile phone information (HPIF') coincide with each other. .

When the received information about the cellular phone (HPIF) and the previously stored cellular phone information (HPIF ') do not coincide with each other, the main processing module 304 based on the received cellular phone information HPIF, the internal state machine 305 Cell phone information HPIF 'is updated and stored (step 1127).

At this time, the mobile phone information HPIF 'other than the phone number of the mobile phone 201 or identification information (ie, identification) of the mobile phone 201 is stored in a flag form. For example, in the entire list of various devices included in the mobile phone, only items for devices that can be controlled by the communication auxiliary device 100 (for example, ringing device and vibration device) are flagged. Stored as "1". When the flag of the ringtone item is "1" and the flag of the vibration item is "0", the communication assistant 100 may control only the ringtone of the connected cellular phone. Also, out of the entire program list, only the items for the programs executable in the mobile phone are stored with the flag "1".

After step 1126 or step 1127, the main processing module 304 transmits, via the phone data transmission module 307, the transmission data packet TDPKT3 including flag information FL1 indicating the connection state of the communication assistance device 100. Transfer to mobile phone 201 (step 1128).

Referring back to FIG. 5, after the connection confirmation of the cellular phone (step 1101) is completed, the USN data receiving module 301 receives the received byte stream data RBST1 from the communication node included in the USN 202 (step 1102). ). The first serialization module 302 generates the received data packet RDPKT1 based on the received byte stream data RBST1 (step 1103).

The filtering module 303 examines the command information CMD included in the received data packet RDPKT1, removes the received data packet RDPKT1 to be processed, and only receives the received data packet RDPKT1 to be processed. By outputting to 304, the received data packet RDPKT1 is filtered (step 1104).

Thereafter, the main processing module 304 examines the command information CMD contained in the received data packet RDPKT1 (step 1105), and determines whether the received data packet RDPKT1 is data for mobile phone delivery (step 1105). Step 1106). If the received data packet RDPKT1 is mobile phone delivery data, the main processing module 304 examines the command information CMD of the received data packet RDPKT1 to determine whether it is data for alarm generation (step 1107).

In the case of alarming data, the main processing module 304 examines the information (HPIF or HPIF ') stored in advance on the mobile phone stored in the internal state machine 305 (step 1108) to determine whether external control of the mobile phone is possible. Determine (step 1109).

When the external control of the cellular phone is possible, the main processing module 304 transmits the transmission data packet TDPKT4 including the external control command to the cellular phone 201 via the phone data transmission module 307 (step 1110). As a result, the cellular phone 201 generates an alarm (for example, a ring tone or vibration) based on the transmission data packet TDPKT4. As an external control command, an AT command commonly used in the mobile phone 201 may be used, or a predefined command may be used.

The main processing module 304 transmits the received data packet RDPKT1 to the mobile phone 201 via the phone data transmission module 307 (step 1111). In step 1107, when the received data packet RDPKT1 is not the alert generation data, step 1111 is executed.

In step 1109, when external control of the cellular phone is impossible, the main processing module 304 outputs the alarm data ARDAT to the display control module 306 (step 1112). The display control module 306 generates its own alarm (visual or audio alarm) of the communication auxiliary device 100 through the status display unit 160 based on the alarm data ARDAT (step 1113), and performs step 1111. Run

On the other hand, in step 1106, when the received data packet RDPKT1 is not data for mobile phone delivery, the main processing module 304, based on the received data packet RDPKT1, sets the setting information (stored in the internal state machine 305). SETIF) is updated or stored, or status display information STPIF stored in the display control module 306 is updated and stored (step 1114).

Communication when the communication assistant device 100 receives the byte stream data from the mobile phone 201. It shows the process of running the support program.

When the plug 101 of the communication assistant 100 is inserted into the socket 210 of the mobile phone 201, the main controller 130 executes a communication support program (TPGM) to confirm the connection of the mobile phone (step 1101). ). The detailed execution process of step 1101 is the same as described above with reference to FIG.

The phone data receiving module 308 receives the received byte stream data RBST2 in a predetermined byte unit from the mobile phone through the communication interface 140 (step 1202). The second serialization module 309 generates the received data packet RDPKT2 based on the received byte stream data RBST2 received from the phone data receiving module 308 (step 1203).

The main processing module 304 examines the command information CMD of the received data packet RDPKT2 received from the second serialization module 309 (step 1204). As a result of this check, the main processing module 304 determines whether the received data packet RDPKT2 is data for communication node delivery (step 1205). When the received data packet RDPKT2 is communication node forwarding data, the main processing module 304 transmits the received data packet RDPKT2 to the corresponding communication node through the USN data transmission module 310 and the wireless communication unit 120. (Step 1206).

On the other hand, when the received data packet RDPKT2 is not data for communication node delivery, the main processing module 304 controls the setting information SETIF or display control of the internal state machine 305 based on the received data packet RDPKT2. The status indication information STPIF of the module 306 is updated and stored (step 1207).

8 is a flowchart illustrating an execution process 1300 of the communication support program of the mobile phone shown in FIG. 3.

First, when the communication support program (for example, PGM1) of the mobile phone 201 is executed (step 1301), the main processing module 322 sends a transmission data packet TDPKT5 for confirming the connection of the communication auxiliary device 100.

In connection with step 1301, the user can operate the input unit (not shown) of the mobile phone 201 to execute the communication support program PGM1. Optionally, the mobile phone 201 may recognize that the communication assistant device 100 is connected to the mobile phone 201 and automatically execute the communication support program PGM1.

The main processing module 322 determines whether the communication assistance device 100 is connected according to whether or not there is a response to the transmission data packet TDPKT5 from the communication assistance device 100 (step 1303). When the communication auxiliary device 100 is connected to the mobile phone 201, the main processing module 322 transmits the transmission data packet TDPKT6 to the communication auxiliary device 100, so that flag information related to authentication information or security information ( Request FL2) to the communication assistance device 100 (step 1304). The main processing module 322 receives the received data packet RDPKT5 including the flag information FL2 related to the authentication information or the security information from the communication assistance device 100 through the serialization module 321 (step 1305). ).

The main processing module 322 updates the internal state information HSPTIF of the cellular phone based on the received flag information FL2 (step 1306). Thereafter, the main processing module 322 communicates with the communication node of the USN 202 through the communication assistance device 100 (step 1307).

On the other hand, in step 1303, when the communication assistance device 100 is not connected to the mobile phone 201, the main processing module 322 stores the warning data HARDAT in the internal state machine 323. As a result, the display control module 324 outputs a warning message based on the warning data HARDAT stored in the internal state machine 323 (step 1308).

Thereafter, the main processing module 322 controls the mobile phone 201 to operate in the restricted mode (step 1309). In the restricted mode, the user can only change simple information in the mobile phone 201 by operating the input of the mobile phone 201, and communication with the communication node of the USN 202 is impossible.

The main processing module 322 periodically transmits a transmission data packet TDPKT5 for confirming connection of the communication auxiliary device 100 to the communication auxiliary device 100 during the limited mode (step 1310), and the communication auxiliary device 100. It is determined whether or not) is connected (step 1311).

When the communication assistant 100 is not connected, steps 1309 to 1311 are repeatedly executed. When the communication assistant 100 is connected, steps 1304 to 1307 are executed.
