Description

  The present invention relates to a base station, a mobile station, a wireless communication system, a method, and a program that perform wireless communication with respect to a work order such as a dispatch order together with polling.

  Patent Document 1 discloses a wireless communication system including a single base station and a plurality of mobile stations (FIG. 1 of Patent Document 1). In the wireless communication system, the time length of the slot allocated to the response of each mobile station in response to the polling command from the base station is changed according to the type of polling command, thereby reducing the communication time required for polling. (Paragraph 0062 of Patent Document 1).

  Patent Document 2 also discloses a wireless communication system including a single base station and a plurality of mobile stations (FIG. 1 of Patent Document 2). In the wireless communication system, mobile stations that are currently dormant are excluded, only mobile stations that are currently operating are extracted, and groups are flexibly assigned to the extracted mobile stations (see paragraphs 0024 and 2 of Patent Document 2). [0035] In the polling command structure, the type of command is described at the top, followed by a response order list (Fig. 3 of Patent Document 2). Even-numbered mobile stations are distinguished into groups 1 and 2 (paragraph 0030 of Patent Document 2), and each mobile station uses radio waves of a frequency assigned to each group and follows the response order for each group. It responds to the base station (paragraphs 0030 and 0035 of Patent Document 2).

  FIG. 12 is a timing chart of data transmission of a base station and a mobile station constituting a conventional personal taxi management wireless communication system. In the conventional wireless communication system, the description overlapping the later-described embodiment of the present invention will be omitted, and the main points will be described.

  In the private taxi driver industry, there is a case where an organization is jointly formed, and the headquarters of the organization distributes dispatches to individual taxis. In order to ensure fair profits for each individual taxi driver, each individual taxi driver sends an application for waiting for dispatch from the mobile station equipped in each taxi to the base station at the headquarters when the vehicle is empty, The allocation of the dispatched vehicles is to transmit the waiting order data as the dispatching waiting order (also referred to as “the dispatching order” as appropriate) to the mobile station.

  The waiting order data is required only for taxis waiting to be dispatched, and is not necessary for taxis that have not applied for a dispatch request because they are transporting or taking a break. On the other hand, the headquarters periodically polls each mobile station to respond to the current location in order to grasp the current location of each mobile station that changes from moment to moment. In the conventional wireless communication system, as shown in FIG. 12, the polling for the position data (current location) response from the base station, the response of the position data from each mobile station, and the standby order data from the base station are timed. It takes up different time in the axial direction.

  FIG. 6A referred to in the description of the following embodiment of the present invention shows a command transmission state from a base station in the conventional wireless communication system according to FIG. In this example, command number = 01 is defined as a polling number for requesting a response of position data (current location) to each mobile station, and command number = 02 is a command for notifying each mobile station of standby order data (allocation order). It is defined as a number. The ID array following the command number is an ID array for identifying each mobile station or its mounted taxi. The ID array in the command of command number = 01 is in the order of response to polling, and the command number = The ID array in the 02 command is the order of dispatch.

  Although details will be described later in the embodiment of the present invention, in FIG. 6A, there are a total of 7 mobile stations with ID = 1 to 7, and currently mobile stations with ID = 2, 5, 6, 1 are present. It is assumed that waiting applications are pending and waiting in turn. In the conventional wireless communication system, the base station transmits a total of three commands in order to make each mobile station respond with position data and to notify the corresponding mobile station of the dispatch order.

In FIG. 12, T1 is the time taken for polling for position data (current location) response from the base station and the response of the position data from each mobile station in the time axis direction, and T2 is transmitted from the base station This is the time that the waiting order data occupies in the time axis direction. The total number of mobile stations that need to collect position data (current location) is n. In the conventional wireless communication system, when the polling and the standby order data are alternately repeated, it takes time (T1 + T2) / n to collect the current location per mobile station.
JP 2007-104597 A JP 2008-131404 A

  In the conventional wireless communication system, when the base station polls the mobile station for the current location and informs the standby order, the number of commands transmitted by the base station 11 is large, for example, three. The time taken to collect the current location per mobile station is as long as (T1 + T2) / n.

  Patent document 1 discloses that the time required for response of each mobile station is flexibly adjusted according to the type of polling to shorten the polling time. However, work from the base station to the mobile station other than polling and polling is disclosed. No specific mention is made of a specific solution for shortening the total communication time and improving the time efficiency of the current location collection from each mobile station when carrying out sequential communication. Similarly, Patent Document 2 discloses reducing the polling time by flexibly allocating mobile stations that are currently in operation. However, no specific solution is mentioned to improve the time efficiency of current location collection from each mobile station by reducing the total communication time.

  An object of the present invention is to shorten the time taken to collect response information of each mobile station and improve communication efficiency when performing polling and business order communication from a base station other than polling to a mobile station. A base station, a mobile station, a wireless communication system, a method, and a program are provided.

  According to the present invention, a polling command in which the response order is matched with the order of work between mobile stations for a predetermined work is generated, and the polling command is transmitted from the base station to the mobile station. The mobile station responds to the base station according to the response order of the polling command, and extracts the work order from the response order of the polling command.

And the work order communication from the base station to the mobile station other than the polling can be integrated into one polling command, thereby eliminating the communication dedicated to the business order communication and collecting the response information from each mobile station It is possible to reduce the time required for

  FIG. 1 is a configuration diagram of a personal taxi operation management system 10 for personal taxi management. The personal taxi operation management system 10 includes a single base station 11 and a plurality of mobile stations 13 each mounted on each personal taxi 12. This personal taxi operation management system 10 assumes that the driver (mobile station 13) of the personal taxi 12 jointly forms an organization, and the headquarters (base station 11) distributes work (allocation). In order to ensure fair profits of the individual mobile stations 13, the base station 11 performs a vehicle allocation work in which the mobile stations 13 allocate work in the order in which they applied for work standby (hereinafter referred to as “standby application” as appropriate). The base station 11 also notifies the mobile station 13 of this information, so that the driver of each mobile station 13 assigns a waiting time to another service when the waiting time is considered sufficiently long, Effective use of time can be achieved.

  For convenience of explanation, the total number of mobile stations 13 in the personal taxi operation management system 10 is 7, and in order to identify each mobile station 13, each mobile station 13 is assigned an identification number of 1-7. Further, the darkly painted individual taxi 12 is currently waiting for a dispatch instruction, and the white individual taxi 12 is not waiting for a dispatch instruction because the customer is being transported. The dispatch instruction is performed by voice from the operator of the base station 11 at the headquarters to the mobile station 13 together with the data, or only the data (in this case, information related to the data is displayed on the display 30 described later). Or you may do it.)

  FIG. 2 is a configuration diagram of the base station 11 and the mobile station 13. The base station 11 includes a PC 17, a modem 18, and a radio device 19. The PC (personal computer) 17 is mounted with vehicle management software. The modem 18 generates a transmission signal corresponding to the polling command from the PC 17, and the transmission signal is transmitted from the antenna of the wireless device 19 on the carrier wave having the frequency assigned to polling in the wireless device 19.

  The radio 19 also receives radio waves from each mobile station 13, converts them into intermediate frequency signals, and supplies them to the modem 18. The modem 18 demodulates the intermediate frequency signal, extracts data, and sends the data to the PC 17. The frequency of the radio wave transmitted from the wireless device 19 to the mobile station 13 and the frequency of the radio wave received from the mobile station 13 are typically different, but may be the same.

  The mobile station 13 includes an input / display terminal 23, a GPS built-in modem 24, and a radio device 25. The driver of the personal taxi 12 operates the operation key 31 (FIG. 3) of the input / display terminal 23 to give various instructions to the mobile station 13, and also displays the display 30 (FIG. 3) of the input / display terminal 23. ) Acquire various information from the display. The GPS built-in modem 24 receives a radio wave from a GPS satellite by the GPS antenna 26, and positions the current location based on the GPS radio wave. The driver's instruction and a signal related to the current location are sent to the radio device 25, and the radio device 25 places the signal on a carrier wave of a predetermined frequency and emits it from the antenna.

  FIG. 3 is a front view of the input / display terminal 23. The input / display terminal 23 includes a display 30 and a plurality of operation keys 31 arranged on the lower side and the right side thereof. One of the operation keys 31 is a standby application (allocation request) button, which is pressed when the driver applies to the base station 11 for standby. In the example of FIG. 3, the current standby order (vehicle dispatch order) is displayed on the display 30, and the standby order is No. 3.

  FIG. 4 shows the data flow of the standby application in the personal taxi operation management system 10. When the driver presses the standby application button of the input / display terminal 23 of the own vehicle, standby application data is sent from the input / display terminal 23 to the GPS built-in modem 24. The GPS built-in modem 24 adds the ID of the mobile station 13 (ID: identifier. In the example of FIG. 4, it is assumed that the ID of the mobile station 13 is “1”) and GPS (position data, that is, Current location information). Thereafter, these pieces of information are transmitted in the order of the wireless device 25 → the wireless device 19 → the modem 18 → the PC 17 and stored in the database of the PC 17.

  On the other hand, the modem 18 returns an ACK (acknowledge) to the wireless device 19 in response to the input of the standby application data, the mobile station 13 ID and GPS, and the ACK is transmitted from the wireless device 19 to the wireless device 25 → GPS. It is transmitted in sequence with the built-in modem 24.

  FIG. 5 is a structure diagram of the polling command. The polling command has a first command number field and a subsequent response order field. A plurality of types of polling commands are set, and the command number is associated with the type of polling command. In the response order field, the mobile station 13 that is requested to respond to polling of the command number describes its ID in response order. In this example, the polling response informs the base station 11 of the current location of each mobile station 13 (corresponding to the position data in FIG. 12), but other than the current location, such as waiting, resting or dispatching. The vehicle status may be notified.

  FIG. 6 is a comparison diagram of transmission modes of commands from the base station 11. (A) is the transmission mode of the command by the base station of the conventional radio | wireless communications system, (b) is the transmission mode by the base station 11 of the personal taxi operation management system 10. FIG.

  The conventional transmission mode is as described above in the background section of the present specification, and the command number = 01 is defined as a polling command number that requests a response of position data (current location) from each mobile station. Command number = 02 is defined as a command number for communicating standby order data (allocation order) to each mobile station. On the other hand, in the personal taxi operation management system 10, a polling command (command number = 01: hereinafter referred to as “dedicated polling command”) requesting each mobile station 13 to respond to its current location, A polling command (hereinafter referred to as “common polling command”) that also serves as a polling (command number = 02) for notifying the mobile station 13 of the standby order from the base station 11 is newly established, and the command number is defined as “03”.

  The stand-by order of the personal taxi 12 (mobile station 13) is assumed to be expressed as ID2-> ID5-> ID6-> ID1 in terms of the ID of the personal taxi 12. In the personal taxi operation management system 10, the base station 11 transmits a dual-purpose polling command with a command number = 03, so that a dedicated polling command with a command number = 01 to the mobile station 13 with ID 2, ID 5, ID 6, ID 1 is transmitted. Transmission can be omitted. Then, the dedicated polling command with the command number = 01 is transmitted only to the mobile station 13 that has not transmitted the shared polling command. As a result, the number of polling commands transmitted from the base station 11 to the mobile station 13 is 2, as shown in FIG. 6 (b), which is smaller than the conventional number of transmissions = 3 in FIG. 6 (a).

  Omission of transmission of the dedicated polling command by transmission of the shared polling command means the disappearance of T2 in FIG. Therefore, the time taken for collecting the current location per mobile station 13 in the personal taxi operation management system 10 is T1 / n, which is shorter than the conventional (T1 + T2) / n by T2 / n.

  A dedicated polling command capable of newly establishing a dual-purpose polling command is sufficient if the response order of the corresponding mobile stations 13 is defined so that they do not overlap each other, as in polling with command number = 01. It is limited to polling that can be any number.

  FIG. 7 shows the flow of a polling command with order data (common polling command). The polling command with order data is generated in the PC 17 of the base station 11 and is transmitted in the order of the modem 18 → the radio 19 → the radio 25 → the GPS built-in modem 24 → the input / display terminal 23, and the input / display terminal 23 displays Displayed on the container 30. The display example on the display 30 is the one shown in FIG. 3 described above, and in FIG. 3, the standby order is displayed as the third. This corresponds to the mobile station 13 with ID 6 in the command number 03 in FIG.

  It supplements about FIG. In FIG. 6, a polling command (command number = 01) for requesting the response of the current location to each mobile station 13 and a command (command number = 02) for notifying the mobile station 13 of the dispatch order (command number = 02). A command (command number = 03) is newly established. In the personal taxi operation management system 10, a polling command of a different type from the polling command (command number = 01) that requests each mobile station 13 to respond to the current location is provided. In the case of preparation, it is also possible to newly establish a command that serves as another type of polling command and a command (command number = 02) for notifying the mobile station 13 of the dispatch order.

  If there is no restriction on the total number of command numbers, a new dual-purpose polling command can be created for each of all existing dedicated polling commands, but typically there are restrictions on the total number of command numbers, A dual-purpose polling command is newly established for only frequently used polling commands or only some of the upper frequently used polling commands.

  In FIG. 6, the number of mobile stations 13 described in the order description part (data field following the command number) for one command is limited to a maximum of four. This is merely for convenience of explanation. For example, the maximum number of mobile stations 13 described in the command order description part may be a number other than four.

  For example, when the maximum number of mobile stations 13 that can be described in the command order description part is 7, in the example of FIG. 6A, the order of all mobile stations 13 is assigned to one command of command number 01. Since it can be described, the transmission of the command with the command number 01 is only one, and the command with the command number = 01 and the command with the command number = 02 can be transmitted one by one. This is the same as the number of commands transmitted in FIG. 6B, and the advantage of newly providing a dual-purpose polling command with command number = 0 is lost. However, when there are about 50 personal taxis 12 that are actually managed, for example, polling of all 50 taxis is not practically performed. This is because when data communication is performed, the receiving side determines the start of data by capturing the SYNC bit (header), and if the mobile station 13 misses the SYNC bit for some reason, it is determined where the data is from. Since it cannot be determined, a series of data following the SYNC bit is all discarded. Especially in the case of wireless transmission, the influence of noise is large, so it is not advantageous to simply send with a long data length, and communication efficiency increases if the data length is limited to a predetermined value that is not so long. .

  Therefore, in the personal taxi operation management system 10, the maximum number m of mobile stations 13 described in the order description part of one polling command is actually larger than the total number n of mobile stations 13 in the personal taxi operation management system 10. It is set to a suitably small predetermined value. Here, the number of mobile stations 13 that communicate the response order by the shared polling command is n1, the number of mobile stations 13 that communicate the response order by the dedicated polling command is n2 (n = n1 + n2), and the quotient of n1 / m Let u be the integer part. In the personal taxi operation management system 10, the number of dual-purpose polling commands transmitted by the base station 11 is u or u + 1, and the number of dedicated polling commands is u (n1) compared to the conventional method (eg, FIG. 6A). / M remainder + n / m remainder> m) or u + 1 (n1 / m remainder + n / m remainder> m). Since the polling command is transmitted periodically, the mobile station 13 can periodically receive the information on the standby order without delay by including the standby order in the polling command.

  When there is a limit on the maximum value of the mobile station 13 described in the order description part of one polling command, if the number of personal taxis 12 waiting for a dispatch instruction exceeds the maximum value m, the notification shown in FIG. In the way, the individual dual-use polling command has a disadvantage that it is impossible to grasp the waiting order of the own vehicles in the individual taxis 12 waiting for all the dispatch instructions. FIG. 8 is an explanatory diagram of transmission / reception of a polling command that can be dealt with when the number of personal taxis 12 waiting to be dispatched exceeds the maximum value m of the mobile station 13 described in the order description part of one polling command. .

  In the data structure of each polling command in FIG. 8, a packet number field is inserted between the command number field and the field describing the response order of the mobile station 13 to be polled. Note that the maximum number m of mobile stations 13 described in the command order description section is assumed to be 4 in the case of FIG. 8 as in FIG.

  This packet number is composed of "main number ID-concatenated number". For example, in the packet number “1-2” on the second line of the transmission command in FIG. 8, “1” before “−” means main number ID = 1, and “2” after “−” Means linking number = 2. The concatenated number determines the concatenation order of the order description parts between polling commands having the same command number and the same main number ID.

  By introducing the main number ID into the polling command, it is possible to determine the standby order for each standby place (eg, taxi stand A, B,...). In the example of FIG. 8, there are a total of 10 personal taxis 12 waiting to be dispatched, and the dispatch order is “2”, “5”, “6”, “in order of the mobile station 13 ID when the main number ID = 1. It is assumed that “1”, “3”, “4”, and “7” are “10”, “8”, and “9” in the ID order of the mobile station 13 when the main number ID = 2.

  The main number will loop a sufficiently large value. For example, when a sufficiently large value is set to 100, the main number circulates in the order of 1 → 2 → 3 →... → 98 → 99 → 100 → 1 → 2 → 3 →. As will be described later, if the information to be written in the dual-purpose polling command is only the connection number, when the mobile station 13 misses reception of some of the dual-use polling commands, the allocation order of the dual-purpose polling commands is connected in the wrong order. The main number has a function to prevent this.

  For example, the base station 11 uses a dual-purpose polling command in which the main number is changed for different types of dispatching orders in which the waiting place and the waiting time zone are different. By looping with a large value, the main number that has been used once is stopped to be used for a while, and erroneous connection of the combined polling command received by the mobile station 13 is prevented. In addition, since the driver of each mobile station 13 knows his / her whereabouts, the base station 11 is not informed of the standby location associated with the main number. The driver of the mobile station 13 waits at his / her place in the order of dispatch in which the base station 11 communicates with the dual-purpose polling command. Even if the mobile stations 13 are in contact with each other using the dual-purpose polling command with the same main number, the waiting locations may be the same (for example, in the case of a personal taxi) or may be different from each other. Yes (for example, a private supplier of a delivery truck).

  In the example of FIG. 8, it is assumed that there are a total of 10 personal taxis 12 waiting to be dispatched and that there are two types of dispatching taxis. Assuming that the main numbers ID = 1 and 2 are the first type and the second type, respectively, the allocation order of the main number ID = 1 is “2”, “5”, “6” in the ID order of the mobile station 13. , “1”, “3”, “4”, “7”, and the allocation order of the main number ID = 2 is “10”, “8”, “9” in the order of ID of the mobile station 13 Assumes.

  The base station 11 continuously transmits three dual-purpose polling commands having a command number = 03, and the packet numbers are 1-1, 1-2, and 2-1, respectively, in the order of transmission.

  On the other hand, the mobile station 13 assembles the response order of polling commands based on the command number and the packet number. In such a case, when a plurality of dual-purpose polling commands having the same command number and the main number ID of the packet number are received in the time axis direction, whether or not their concatenated numbers are consecutive from 1 in the order of reception. Is inspected. If it is started from a linking number other than 1, it is determined that the response order of each polling command is valid, and the response order is determined, but the business order is determined to be invalid. And give up the extraction of work order. In addition, when discontinuity occurs in the connection number, the response order is extracted from the combined polling command from the connection number 1 to the last continuous connection number, and they are connected according to the connection number. For dual-use polling commands with discontinuous numbers and subsequent dual-use polling commands, the response order of each dual-use polling command is judged to be valid, and responses are made in the specified response order, but the work order is invalid. Judge that there is, and give up extracting the work order.

  In the response order concatenation process, the head of the response order extracted from the combined polling command of the next concatenated number of the combined polling command is concatenated to the end of the response order extracted from the shared polling command. In the example of FIG. 8, in the mobile station 13, the response orders extracted from the combined polling commands of the packet numbers 1-1 and 1-2 are connected to each other before and after, respectively. The response order after connection matches the business order before division in the base station 11.

  Since the response order of the shared polling command for the packet number 2-1 is a response order that is different from the response order of the shared polling commands for the packet numbers 1-1 and 1-2, the shared polling for the packet number 1-2 is performed. Instead of connecting in response order of commands, it is extracted as another dispatch order.

  As an example of a communication failure, the base station 11 sends a combined polling command with a command number = 03 in total from packet numbers 1-1, 1-2, 2-1, 1-1, 1-2 in order. Suppose that a single poll command is sent. On the other hand, it is assumed that the mobile station 13 cannot receive the shared polling command with the second packet number = 1-2 and the shared polling command with the fourth packet number = 1-1 for some reason. In this case, the mobile station 13 sequentially receives the combined polling commands of the packets 1-1, 2-1, and 1-2 with the command number = 03. However, since a dual-purpose polling command with a packet number = 2-1 having a different main number ID is sandwiched between the packet numbers 1-1 and 1-2, The response order is not linked, and the data of the dual-purpose polling command with the packet number 1-2 is discarded as the business order.

  Furthermore, a specific example of the significance of the main number will be described. If the main number is not looped with a large value, it is assumed that the first and second types of dispatching order are fixed to the main numbers 1 and 2, respectively, or the main number is looped at 2. In the above example, it is assumed that the mobile station 13 cannot receive the dual-purpose polling command with the second packet number = 1-2 and the dual-purpose polling command with the fourth packet number = 1-1 for some reason. However, it is further assumed that the third packet number = 2-1 could not be received. In this case, the first packet number = 1-1 and the fifth packet number = 1-2, which should not be concatenated originally, are erroneously concatenated and the mobile station 13 grasps the wrong dispatch order. By looping the main number with a large value, the packet number of the shared polling command from the base station 11 is 1-1, 1-2, 2-1, 3-1, 3-2, 4-1,. It is possible to prevent erroneous connection in the mobile station 13 by changing the order of transmission such as 100-1, 1-1, 1-2,.

  FIG. 9 is a configuration diagram of the wireless communication system 48. The wireless communication system 48 includes a single base station 50 and a plurality of mobile stations 60. For simplification of illustration, only one mobile station 60 is shown in FIG. A specific example of the wireless communication system 48 is the above-described personal taxi operation management system 10 (FIG. 1). However, in the individual truck management system in which each individual delivery company owns his own truck and delivers cargo. Is also applicable. The mobile station 60 mounted or carried is not limited to a taxi, but may be a truck, a bus, a motorcycle, or a bicycle, and may be a predetermined worker or associate (eg, a station worker, a store clerk, or a courier). May be.

  The base station 50 includes a work order determining unit 51, a polling command generating unit 52, a transmitting unit 53, and a receiving unit 54. The work order determining unit 51 determines the work order between the mobile stations 60 related to a predetermined work. The polling command generation means 52 generates a polling command 58 with business communication, which is a polling command including a command ID and a response order, the command ID is a polling ID with business communication, and the response order is a business order. The transmission means 53 transmits a polling command 58 with business communication. The receiving means 54 receives the response 68 transmitted from the corresponding mobile station 60 according to the response order of the polling command 58 with business communication.

  The predetermined work is, for example, a management work for a vehicle or a worker on which the mobile station 60 is mounted or carried, and corresponds to a personal taxi dispatching work in the personal taxi operation management system 10. The work order corresponds to the dispatch order in the personal taxi operation management system 10. The command ID corresponds to the command number in each command in FIG. A specific example of the polling command with business communication 58 is the polling command with the command number = 03 in FIG. The response 68 from the mobile station 60 to the base station 50 is, for example, notifying the base station 50 of the current location of each mobile station 60.

  In this way, the polling command 58 with business communication in which the response order of the polling command is matched with the business order is generated, and the polling command 58 with business communication is transmitted from the base station 50 to the mobile station 60. It is possible to omit a command dedicated to contact in order, and accordingly, the frequency of polling commands can be increased, and the time taken for the response 68 of each mobile station 60 can be shortened. In addition, since the base station 50 periodically transmits the polling command 58, the mobile station 60 can periodically receive the standby order information without delay by including the standby order in the polling command. .

  Typically, the receiving unit 54 receives a request signal for requesting that the mobile station 60 be added to the target of the work order from the mobile station 60. On the other hand, the work order determining means 51 determines the work order based on the order in which request signals are received from the mobile stations 60. The business order determining unit 51 can determine the business order in consideration of not only the order in which request signals are received from the mobile stations 60 but also the current location of each mobile station 60. This specific example has been described with reference to FIG. For example, in a personal taxi, when a passenger is transported, becomes empty, and requests the next customer, a request for waiting to be dispatched is issued, and the headquarters makes the order in which the request signals are received as the order of application. Fair and equal treatment can be achieved for each individual taxi driver.

  As described above, in the wireless communication system 48, the work order is, for example, the order of taxi dispatch. In this case, the polling command generation means 52, when generating the polling command, the mobile station 60 that is requesting dispatch notification. And the mobile station 60 that is not requesting vehicle dispatch communication, and for the mobile station 60 that is requesting vehicle dispatch communication, a polling command 58 with business communication is generated to include them in the order of response. For the station 60, a business communication no polling command including them in response order is generated, and the transmission means 53 transmits the business communication no polling command. And the receiving means 54 receives the response 68 from the mobile station 60 which is not requesting vehicle dispatch according to the response order of the polling command without business communication. A specific example of the business communication no polling command is the polling command with command number = 01 in FIG.

  Generally, the maximum number of mobile stations 60 included in the response order information of one polling command with business contact 58 is smaller than the total number of mobile stations 60 in the wireless communication system 48. Therefore, the total number of mobile stations 60 that wish to be notified of the business order may be larger than the maximum number, and in this case, the entire business order may not be included by one response 68.

  In response to this, preferably, the polling command generating means 52 is a plurality of polling commands 58 with business communication in which the business order is divided into a plurality of sections and each section is in each response order. A plurality of business communication polling commands 58 including connection information that defines the connection order when assembling the order are generated. A specific structure of the polling command with business contact 58 is a polling command with a packet number shown as a transmission command in FIG. The concatenation number on the right of “-” in the polling command with a packet number in FIG.

  Preferably, the business order determining unit 51 assigns a transmission number in the order of transmission for each series of polling commands with business communication from the first to the last in the connection order, and includes information related to the transmission number. A contact polling command 58 is generated. A specific example of the transmission number is the main number in the packet number of FIG. The transmission number is typically a number obtained by circulating a range from 1 to a sufficiently large value (for example, 100). In this way, the polling command with business communication in which the connection number is continuous even though a part of the polling command with business communication 58 transmitted by the base station 50 including the information of the connection number is not received by the mobile station 60 due to a communication error or the like. Even if 58 is received by the mobile station 60, the mobile station 60 can determine that the polling command 58 with business contact is a different series, and there is an error between the polling commands 58 with business contact. It is possible to prevent recognition of an incorrect work order due to connection.

  The mobile station 60 includes a receiving unit 61, a transmitting unit 62, and a work order extracting unit 63. The receiving means 61 receives the polling command 58 with business communication. The transmission means 62 transmits the response 68 according to the response order of the response order information of the polling command 58 with business contact. The business order extracting unit 63 extracts the business order of the own device from the response order information for the polling command 58 with business communication.

  Preferably, the transmission means 62 transmits a request signal (for example, standby application data in FIG. 4) requesting that the own device is added to the target of the business order.

  Typically, the business order is the taxi dispatch order, and the receiving means 61 receives the business communication polling command 58 and the business communication no polling command. Further, the transmission means 62 transmits a response 68 in the response order based on the response order information of the polling command 58 with business contact while the own device is requesting dispatch, and when the own device is not requesting dispatch, A response 68 is transmitted according to the response order of the response order information of the polling command without business communication.

  The mobile station 60 can further include business order assembly means 65. The receiving means 61 is a plurality of business communication polling commands 58 that divide the business order into a plurality of sections and set each section as a response order, and define the connection order when assembling the entire response order from each response order. A plurality of business communication polling commands 58 including the connection information are received. Then, the business order assembling means 65 assembles the entire response order from the response order of the plurality of polling commands with business communication 58 based on the connection information of the plurality of polling commands with business communications 58, and the business order extracting means 63 is assembled. Extract the work order of your own machine from the overall response order. The specific way of assembling the response order of the polling command 58 with business communication by the business order assembling means 65 is as described above in “Assembly on the receiving side” in FIG.

  Preferably, the receiving unit 61 assigns a transmission number to each transmission sequence of the polling command with business communication from the first to the last in the connection order, and the base station 50 assigns a transmission number in the order of transmission, and information related to the transmission number is obtained. The business order extraction means 63 receives the business command polling command with business contact and extracts the business order for each region based on the region information of the polling command with business contact 58.
