Include.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

First, terms used in the present invention are defined as follows.

The forward channel refers to a radio channel in a direction transmitted from the base station to the terminal. This applies to both radio calling networks and mobile communication networks. In the case of a mobile communication network, it consists of a control channel and a voice channel.

The reverse channel refers to a radio channel in a direction transmitted from the terminal to the base station. This is applied to a mobile communication network and consists of a control channel and a voice channel.

The forward path is the data path in the direction from the terminal to the terminal, and the reverse path is the data path in the direction from the terminal to the terminal.

The end device is a paging terminal originally used in a wireless call network, and generates a paging information by interworking with a public communication network and sends it to a pager. In the present invention, a function is added to the paging terminal to process the information received in the reverse path, so that the data is exchanged with the data processor directly or through a public communication network (PSTN).

The reverse controller extracts information from the terminal message received through the mobile communication network and delivers the information to the end device.

The IS-41 protocol is a protocol for interworking various devices in a mobile communication network. There are revisions such as A, B, and C. Currently, the mobile communication network uses the A revision. In the present invention, since the reverse controller operates as a kind of home location register, it is used to interwork with the mobile communication network.

1 is a configuration diagram of a wireless data service system according to the present invention, in which 11 is a data processor, 12 is a public communication network, 13 is an end device, 14 is a wireless call network, 15 is a transmitter, 16 is a terminal, and 17 is a receiver. , 18 denotes a mobile communication network, and 19 denotes a reverse controller.

At present, in order to provide a two-way wireless data service in consideration of subscriber capacity, it is essential to introduce a cellular concept in wireless calling.

The cellular concept introduction method of the present invention is as follows. The end device checks the location of the terminal and delivers a message to a specific radio calling transmitter (or transmitter group) corresponding thereto. The radio call transmitter periodically transmits its location information to the terminal. When the location information changes, the terminal transmits the location information through a reverse path using an existing analog mobile telephone network (AMPS Cellular). The terminal can be easily implemented as a combination of a wireless call terminal and an analog mobile telephone network terminal. Since the existing network is used, no additional installation cost is required, and the mobile communication network can be used as it is. By integrating a reverse controller, which is a separate device, can provide services without changing the existing analog mobile communication system.

The data processor 11 may have various appearances and various functions according to an application service. In the case of an interactive paging application service, the data processor 11 may be a telephone. That is, when the user calls the terminal 16 and the terminal 16 sends a reception confirmation message, the end device 13 makes a call and informs the user of the reception or stores a response using a voicemail. The user can make a call to see if the call is received. In the case of this two-way paging service is connected to the terminating device 13 through the public telephone network (12).

In the case of a telemetry application service measuring a gas meter or the like, the data processor 11 may be a gas usage measurement data collector of a gas company. The data collector sends a data request message to the terminating device 13 to collect data of each place on a predetermined date. The terminal 16 reads the data value of the meter and sends the measured value through the mobile communication network 18, and the data processor 11 receives it from the terminating device 13 and processes it. In a service such as telemetry, the data processor 11 may be connected through a public telephone network 12 or directly to an end device 13.

The terminator 13 receives its information from the data processor 11 via the public telecommunication network (PSTN) 12 or directly from the data processor 11 without receiving the information from the data processor 11 according to the application service. Searches for the terminal location information, the corresponding frequency information, and transmits the information to the base station transmitter 15 through the wireless call network 14, and the base station location received from the reverse controller 19 through the reverse path of the mobile communication network 18. The information is stored in its own database and the data is sent to the data processor 11. Meanwhile, the transmitter 15 transmits its base station location information and the received information to the terminal 16.

The terminal 16 receives the information transmitted from the transmitter 15, and the base station 16 and the base station position information on the turn-on or base station information change, such as the acknowledgment message, the response message, the start of the message, etc. In the case of a telemeter, measurement data and the like are sent to the receiver 17. Meanwhile, the terminal 16 tunes its forward service channel according to the base station location information of the wireless call network, and tunes its reverse control channel according to the base station of the mobile communication network. Therefore, the terminal 16 should have a look-up table of the base station location information and the service frequency in the memory. The base station location information may be sent in a service channel or a separate channel, may be actual latitude / longitude, and may also be a base station identifier (ID).

The receiver 17 receives the message transmitted from the terminal 16 and the base station location information and transmits the message to the reverse controller 19 through the mobile communication network 18.

The reverse controller 19 receives the message transmitted from the mobile communication network 18 and the location information of the base station, extracts the data and the mobile station identification (MIN) number, and transmits it to the terminating device 13.

The reverse controller 19 operates as a kind of home location register which connects to and cooperates with the mobile communication network 18 through the IS-41 protocol. The mobile terminal identification (MIN) number of the terminal is registered in the reverse controller 19 and operates as if roaming at all times. Accordingly, the registration recognition message and the remote personality control message sent by the terminal 16 are transmitted to the reverse controller 19 through the mobile communication network 18. The reverse controller 19 extracts the mobile station identification (MIN) number and data from the message received from the terminal 16. The extracted mobile terminal identification (MIN) number and data are transmitted to the end device 13.

Terminal 16 will have two subscriber numbers. One is a radio call number, and the number format is network identification number (012 or 015) + subscriber number. The other is a mobile terminal identification number (MIN number) of the mobile communication network, the number format is a network identification number (service identification number) + subscriber number. The network identification number is used to identify existing networks. This network identification number is used as a service identification number, which uses a separate number not used in a cellular network. That is, 02, 012, etc. are already used numbers. Therefore, a three-digit number such as 411 can be used as the service identification number. This service identification number allows the reverse controller 19 to send a message. Each of the two subscriber numbers may be the same or different depending on the reverse service provider.

The form of the terminal 16 may be in the form of a single product, such as a two-way pager, or may be a board-level product in the case of a telemeter for remote meter reading. In the case of a telemeter, the terminal may be fixed in one place or installed in moving equipment.

On the other hand, in order to extend the battery usage time may be implemented using the following method.

In other words, upon receiving the information from the data processor 11, the terminating device 13 broadcasts the terminal address through the wireless call network 14 and requests the terminal 16 to check the terminal position.

Then, the terminal 16 transmits the current base station position information to the terminating device 13 through the receiver 17, the mobile communication network 18, and the reverse controller 19.

2 is a detailed configuration diagram of a terminal according to the present invention, in which 21 is a paging signal receiving processor, 22 is a user matching unit, 23 is a paging signal receiving unit, 24 is a mobile telephone signal transmitting and receiving unit, 25 is a mobile telephone signal transmitting and receiving processor Respectively.

The paging signal receiver 23 receives a paging radio frequency (RF) signal from the transmitter 15 of the wireless call network 14, extracts a paging message, and transmits the paging message to the paging signal receiving processor 21.

When the paging signal receiving processor 21 receives the paging message from the paging signal receiving unit 23, the paging signal receiving processor 21 extracts data and transmits the data to the user matching unit 22.

The user matching unit 22 may vary in function depending on the application service. For example, in the case of bidirectional paging, the user matching unit 22 outputs the received data on the screen and informs the terminal user of the alarm sound. At this time, the response message for the received message may be automatically transmitted to the mobile phone signal transmission / reception processing unit 25 according to a selection, or when the terminal user manually presses a response button or the like, the response message for the received message may be transmitted or received. It may also transmit to the processing unit 25. In a service such as telemetry, the received data is analyzed (primarily a measurement command, etc.), and the corresponding measurement is performed and transmitted to the mobile phone signal transmission / reception processing unit 25.

The mobile phone signal transmission / reception processor 25 always knows the traffic state of the reverse control channel from the mobile phone signal transmission / reception unit 24 by viewing. Upon receiving the data to be sent from the user matching section 22, the mobile telephone signal transmission / reception processing section 25 transmits the data to the mobile telephone signal transmission / reception section 24 when the traffic state of the reverse control channel does not exceed the threshold. The threshold value should be set in such a way that it does not affect the existing mobile subscribers, and usually 50% to 60% is appropriate.

The mobile phone signal transmission / reception unit 24 modulates the data transmitted by the mobile phone signal transmission / reception processing unit 25 into an RF signal and transmits the signal to the receiver 17 of the mobile communication network 18.

3A and 3B are exemplary views illustrating frequency reuse of a forward wireless paging network according to the present invention.

FIG. 3A is a method of allocating one frequency using one base station (or transmitter) as a cell unit, and FIG. 3B is a method of allocating one frequency by configuring three base stations in one cell unit. Depending on the traffic capacity, these two methods can be mixed to provide flexibility in cell design.

4 is a message flow diagram of a forward path according to the present invention.

First, look at the wireless data service method used to increase the battery life of the terminal as follows.

When the transmitter 15 receives the data processing request from the data processor 11 while transmitting the base station location information to which the transmitter 15 belongs periodically (for example, 1 minute) (32) When the terminal 16 requests a location check (33), the terminal 16 transmits its location information to the terminating device 12 through the receiver 17 and the reverse controller 19 (34 to 36).

Subsequently, the terminal device 12 transmits the information to the terminal 16 through the base station transmitter 15 identified through the location information (37, 38), and the terminal 16 receives the information and sends a response signal to the receiver 17. And to the terminating device 12 via the reverse controller 19 (39 to 41). Thereafter, the terminating device 12 transmits a response signal to the data processor 11 (42), and if an error occurs, performs the information retransmission process (43).

Meanwhile, the wireless data service method without considering the battery usage time of the terminal is as follows.

When the transmitter 15 receives the data processing request from the data processor 11 while transmitting the base station position information to which the transmitter 15 belongs periodically (for example, 1 minute) (32), the terminating device 12 Retrieves the location information of the base station to which the terminal belongs and the corresponding frequency information from its database.

Thereafter, the end device 12 transmits the information to the terminal 16 through the base station transmitter 15 retrieved from the database (37, 38), and the terminal 16 receives the information and sends a response signal to the receiver 17. And to the terminating device 12 via the reverse controller 19 (39 to 41). Thereafter, the terminating device 12 transmits a response signal to the data processor 11 (42), and if an error occurs, performs the information retransmission process (43).

At this time, the terminal 16 transmits its location information to the end device (paging terminal) 12 through the reverse path at the time of the turn-on (Trun-ON) or when the base station information changes.

When the data processing process is a radio call, the terminal 16 grasps the radio call information and the terminal location information unlike the conventional radio call system, converts the radio call protocol (POCSAG, FLEX, APOC, etc.) into a predetermined radio call protocol. The call message is transmitted to the base station transmitter 15 via the link.

The number of a radio calling terminal is a subscriber number and a number of the terminal machine itself called a CAP code. The subscriber number is as described above, and in the case of a cap code (CAP CODE) is used as follows. It is divided into single cap code and group cap code, and each terminal has different cap code so that it can communicate 1: 1, or group cap code This allows all terminals to respond in one paging. When the actual terminal sends a message, it uses the reverse control channel of the mobile communication network and measures the data traffic of the control channel and sends the data only when it is below a certain level. Therefore, it does not affect the service for existing cellular subscribers at all.

5 is a message flow diagram of a reverse path in accordance with the present invention.

First, in a state in which the transmitter 15 periodically transmits base station position information to which it belongs (for example, 1 minute) (51) when the terminal is turned on or when the base station information changes, the terminal 16 Transmits its location information to the terminating device 12 via the receiver 17 and the reverse controller 19 through the reverse path (52 to 54).

Thereafter, the terminal 16 transmits a response message or the like to the terminating device 12 through the receiver 17 and the reverse controller 19 (55 to 57), and the terminating device 12 sends a message to the data processor 11. If the error is confirmed (58) and an error occurs (59), the message retransmission process is performed.

The terminal 16 loads and sends data to be sent to the end device 12 together with its mobile terminal identification (MIN) number. Data is loaded in the serial number (ESN) field and the 16 digit (DIGIT) fields (the ESN field may not be used). For example, the last bit of the serial number (ESN) is used as an extended bit, and when the last bit is 0, only the serial number (ESN) is returned. When the last bit is 1, the digit bits are also used. Use as data. At this time, in order to facilitate a sequence from the receiver 17 of the mobile communication network 18 to the reverse controller 19, a Remote Feature Control Request (e.g., * 71 ...) message is sent. Send by using. Since the format of the reverse data varies depending on the application service, each data type suitable for the application service is used. The reverse controller 19 extracts the mobile station identification (MIN) number and data from the frames received from the terminal 16. Of course, the extraction method and contents can be changed according to each application service. The extracted mobile terminal identification (MIN) number and data is sent to the end device 12 or a separate interworking equipment. At this time, the protocol to send and receive can be properly defined and used.

6 is a detailed flowchart of a reverse path message according to the present invention.

Here is an example of using a remote property control message.

The terminal 16 transmits a registration recognition message including the mobile terminal identification number (MIN) and the serial number (ESN) carrying data to the reverse controller 19 through the mobile communication network 17 when the data to be transmitted is generated (61). (62).

The reverse controller 19 extracts the mobile station identification number (MIN) from the registration recognition message, extracts the necessary data from the serial number (ESN), and then transmits the registration recognition result message to the terminal 16 (63). That is, the reverse controller 19 transmits an invalid registration recognition result message to the terminal 16 when it receives all necessary data, and a valid registration recognition result message when it needs to receive more.

If a valid message is received (i.e. there is more data to send), the terminal 16 adds the necessary data in the remote feature control message (dial number: * 71 ...) (64) and the reverse controller (19). After receiving all necessary data, transmits a successful remote feature control result message to the terminal 16 (65). At this time, the authorization period in the message is sent as a per call. If the data is long, the above process is repeated to transmit the data, and the continuity of the message is guaranteed at the application service data transport layer.

Thereafter, the reverse controller 19 transmits the mobile station identification number MIN and the extracted data to the terminating device 13 (66), and the terminating device 13 transmits the data to the data processor 11 (67). .

7 is a message processing flowchart of a reverse controller according to the present invention.

The reverse controller 19 receives the registration recognition message from the terminal 16 (72) while waiting for a message from the terminal 16 (71) after performing the initialization (71) and receives the mobile terminal identification number (MIN). If it is not a valid subscriber, it transitions to the message waiting state (72). If it is a valid subscriber, it extracts the data of the field of the serial number (ESN) (75). It is determined whether all have been received (76).

As a result of the determination, when all necessary data is received, an invalid registration recognition result message is transmitted to the terminal 16 (77), and the data is transmitted to the terminating device 13 (82). The recognition result message is transmitted to the terminal 16 (78).

After receiving the remote characteristic control message (dial number: * 71 ...) from the terminal 16 (79), the required data is extracted (80), and after the remote characteristic control result message is transmitted to the terminal 16 ( 81) The received data and the mobile station identification number (MIN) are transmitted to the terminating device 13 (82).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention can provide a low-cost two-way wireless paging service in a cellular form using an existing mobile communication network, and improves frequency use efficiency by implementing cell-based services such as frequency reuse in a wireless paging network. It can provide various application services such as voice paging and telemetry, and it is possible to design a flexible cell according to traffic capacity, and to implement the service by using existing radio calling transmitter and partially modifying / improving the paging terminal. In addition, since the reverse control channel of the mobile communication network is used, the existing voice mobile communication service is not affected.
