Description

【Technical Field】 【0001】 The present disclosure relates to a mobile communication system, an on-vehicle communication control device, and a central device that use a public wireless network provided by a telecommunications carrier. 【Background Art】 【0002】 In the field of public safety, a narrowband private wireless communication system network has been constructed for use mainly for the purpose of a communication function. The private wireless communication system network is a private train wireless system. In the private wireless communication system network, a large number of unspecified lines are not shared. As a result, the private wireless communication system network has been established as a reliable communication means that can be surely used without communication failure even in case of a disaster. 【0003】 However, the private wireless communication system network has a constraint on a wireless communication band. Therefore, in the private wireless communication system network, the available wireless lines are limited. Thus, in order to newly increase the number of communication lines, it is considered to perform function addition that cannot be realized in the private wireless communication system network by utilizing the public wireless network provided by a telecommunications carrier. The public wireless network is a public wireless communication line. In the following, the communication line between a command center and a passenger compartment of a train is also referred to as a "command-compartment communication line". 【0004】 Particularly in the future, it is considered that the demand for constructing a command-compartment communication line will increase in railway operators where automation (that is, without crew) progresses. 【0005】 Patent Document 1 discloses a configuration (hereinafter, also referred to as "related configuration A") for establishing a communication path when there is a line connection request from a passenger compartment communication terminal in a situation where a private wireless communication system network is not constructed. In related configuration A, a call exchange server that stores the on-line position information of each train associates a passenger compartment communication terminal and a crew communication terminal based on the on-line position information of each train. Thereby, a communication path is established. In the following, the private wireless communication system network is also referred to as a "private network". 【Prior Art Documents】 [Patent Documents] 【0006】 [Patent Document 1] Japanese Patent Publication No. 2021-082956 [Overview of the project] [Problems that the invention aims to solve] 【0007】 In train radio systems, there are situations where it is necessary for passenger-operated in-cabin communication terminals to communicate with a control console operated by an operator. This situation occurs, for example, when a passenger discovers a malfunction in the train. 【0008】 To ensure reliable communication between the in-room communication terminal and the control console, it is desirable to use a configuration that utilizes the public wireless network provided by the telecommunications carrier to secure a sufficient number of communication lines. 【0009】 Related Configuration A discloses a process in which a cabin communication terminal communicates with a command center terminal, which is a control console, using a public wireless network provided by a telecommunications carrier. 【0010】 Some train radio systems have a configuration in which multiple control consoles, each responsible for a different railway line, are used. In this configuration, the passenger communication terminal communicates with the control console responsible for the railway line where the train is located. Even in this configuration involving multiple control consoles, it is required that the passenger communication terminal communicates with the control console using a public radio network. Related configuration A assumes a situation where only one control console is used, and therefore cannot satisfy this requirement. 【0011】 This disclosure is made to solve such problems and aims to provide a technology that enables a cabin intercom terminal to communicate with a command and control console using a public wireless network in a situation involving multiple command and control consoles. [Means for solving the problem] 【0012】 To achieve the above objective, a mobile communication system according to one aspect of this disclosure performs processing using a privately owned train radio communication system network, which is a privately owned train radio system, and a public radio network provided by a telecommunications carrier. The privately owned train radio communication system network has train information, which is information about trains in operation. The mobile communication system comprises a plurality of control consoles, each responsible for different railway lines, a passenger compartment telephone terminal installed in the passenger compartment of a train, and a control device that selects a target control console, which is a control console responsible for the railway line where a train is located, from among the plurality of control consoles based on train information obtained from the privately owned train radio communication system network. The control device performs processing to establish a target communication path, which is a communication path for the passenger compartment telephone terminal to communicate with the target control console via the public radio network. [Effects of the Invention] 【0013】 According to this disclosure, the control device selects a target control console from among several control consoles, which is the control console responsible for the line section where the train is located, based on train information obtained from the private train radio communication system network. The control device then performs processing to establish a target communication path, which is a communication path for the passenger compartment communication terminal to communicate with the target control console via the public radio network. 【0014】 This allows the cabin communication terminal to communicate with the control console using a public wireless network, even in situations involving multiple control consoles.

In the following drawings, the same components are denoted by the same reference numerals. The names and functions of the components denoted by the same reference numerals are the same. Therefore, detailed descriptions of some of the components denoted by the same reference numerals may be omitted. 【0017】 <Embodiment 1> (Configuration) FIG. 1 is a diagram showing the configuration of a mobile communication system 1000 according to Embodiment 1. The mobile communication system 1000 is an in-vehicle communication system having a call function. A private network is constructed in the mobile communication system 1000. The mobile communication system 1000 is a system that provides a new call service using a public wireless network provided by a telecommunications carrier. 【0018】 Specifically, it is expected that railway operators will increasingly introduce systems for communication between the control center and passenger cabins. This communication between the control center and passenger cabins is between the passenger cabin communication terminal and the control center console. As will be explained in more detail later, the mobile communication system 1000 is a system that, when a connection request is received from a passenger cabin communication terminal, utilizes the public wireless network provided by the telecommunications carrier to establish a communication path between the passenger cabin communication terminal and the control center console responsible for the railway line where the train is located. 【0019】 The mobile communication system 1000 comprises a private train radio communication network N1, an onboard communication control device 10, a ground communication control device 11, and a passenger compartment communication terminal 14. In other words, the mobile communication system 1000 performs processing using the private train radio communication network N1. The mobile communication system 1000 also performs processing using the public radio network N2, which will be described later. 【0020】 The privately operated train radio communication system network N1 is the aforementioned privately operated radio communication system network. The privately operated train radio communication system network N1 is a privately operated train radio system. 【0021】 Figure 1 shows train MV1. Hereafter, information about train MV1 in operation will also be referred to as "train information Jt" or "train information". The private train radio communication system network N1 is aware of train information Jt. 【0022】 Train MV1 travels along the railway tracks. A portion of the railway track is called a section of track. In other words, a railway track has multiple sections of track. In the following, two adjacent sections of track will also be referred to as section A and section B, respectively. In this embodiment, section A and section B will be used as the sections of track on which train MV1 travels. 【0023】 The privately operated train radio communication system network N1 includes a central unit 1, multiple command and control consoles 2, multiple base station groups 4, and a train radio mobile station 7. The central unit 1, each command and control console 2, and each base station group 4 are ground-based facilities. 【0024】 Multiple control consoles 2 are installed, for example, in a control room. Figure 1 shows two control consoles 2 as an example. Note that the number of control consoles 2 included in the private train radio communication system network N1 is not limited to two, but may be three or more. 【0025】 Each of the multiple control consoles 2 is responsible for a different railway line. Each control console 2 is, for example, a PC (Personal Computer). Each control console 2 has various functions. Each control console 2 has, for example, a function for making phone calls. Each control console 2 is operated by a different operator 12. Hereafter, among the multiple control consoles 2, the control console 2 responsible for the railway line where train MV1 exists will also be referred to as the "target control console". 【0026】 Furthermore, in the following, the two command consoles 2 shown in the mobile communication system 1000 in Figure 1 will also be referred to as command console 2A and command console 2B, respectively. Command console 2A is responsible for line section A. In the following, command console 2A will also be referred to as the "command console for line section A". Command console 2B is responsible for line section B. In the following, command console 2B will also be referred to as the "command console for line section B". 【0027】 The train radio mobile station 7 and the onboard communication control device 10 are mounted on train MV1. The train radio mobile station 7 and the onboard communication control device 10 move as train MV1 moves. 【0028】 The passenger compartment communication terminal 14 is, for example, a telephone. The passenger compartment communication terminal 14 is installed in the passenger compartment of train MV1. The passenger compartment communication terminal 14 is used by passengers 13 present in the passenger compartment of train MV1 as needed. The passenger compartment communication terminal 14 moves as train MV1 moves. 【0029】 Furthermore, the multiple base station groups 4 shown in Figure 1 constitute the train radio network as a communication network. The train radio network is a ground-based facility. Figure 1 shows three base station groups 4 as an example. Note that the number of base station groups 4 included in the private train radio communication system network N1 is not limited to three, but may be two or four or more. Each base station group 4 has the function of performing radio communication. 【0030】 In Figure 1, "train radio base station" is abbreviated as "base station." Each base station group 4 consists of multiple train radio base stations K4. Each base station group 4 constitutes a zone. Hereafter, the three base station groups 4 shown in the mobile communication system 1000 in Figure 1 will also be referred to as base station group 4a, base station group 4b, and base station group 4c, respectively. 【0031】 Base station groups 4a and 4b can communicate with train MV1 located on line A. In other words, base station groups 4a and 4b correspond to line A. Base station group 4c can communicate with train MV1 located on line B. In other words, base station group 4c corresponds to line B. 【0032】 In the following, the zone comprised of base station group 4a will also be referred to as "Line A Zone a". Similarly, the zone comprised of base station group 4b will also be referred to as "Line A Zone b". Furthermore, the zone comprised of base station group 4c will also be referred to as "Line B Zone a". Each of Line A Zone a, Line A Zone b, and Line B Zone a is assigned a base station ID to identify the zone (i.e., base station group 4). 【0033】 The train radio mobile station 7 has the function of performing wireless communication. The train radio mobile station 7 has the function of performing wireless communication with base station group 4. Specifically, the train radio mobile station 7 has the function of performing wireless communication with train radio base station K4, which is included in base station group 4. 【0034】 Each train radio base station K4 included in each base station group 4 periodically transmits line section information to the line section corresponding to that base station group 4. The line section information identifies the line section where train MV1 is located. The line section information is the aforementioned train information Jt. Base station group 4a or base station group 4b corresponding to line section A transmits line section information indicating line section A to line section A. If train MV1 is located in the line section corresponding to base station group 4, the train radio mobile station 7 of train MV1 receives the line section information. For example, if train MV1 is located in line section A corresponding to base station group 4a, the train radio mobile station 7 of train MV1 receives line section information indicating line section A. 【0035】 The public wireless network N2 is a wireless network provided by a telecommunications carrier. The public wireless network N2 includes a terrestrial public wireless network 8 and public wireless terminals 9. 【0036】 The terrestrial public wireless network 8 is a public wireless network provided by a telecommunications carrier. This public wireless network is, for example, a network conforming to the LTE (Long Term Evolution) communication standard. The mobile communication system 1000 performs processing that utilizes the terrestrial public wireless network 8. 【0037】 The public radio terminal 9 is mounted on train MV1. The mobile communication system 1000 includes the public radio terminal 9. The public radio terminal 9 has the function of wirelessly communicating with the terrestrial public radio network 8. That is, the public radio terminal 9 is capable of communicating with the terrestrial public radio network 8. The public radio terminal 9 is capable of communicating with the terrestrial communication control device 11 via the terrestrial public radio network 8. 【0038】 The ground communication control device 11 is a ground-based facility. The ground communication control device 11 can communicate with the ground public radio network 8, the central unit 1, the command console 2A, and the command console 2B. 【0039】 The central unit 1 is a control device that controls the devices included in the private train radio communication system network N1. The central unit 1 can communicate with the ground communication control device 11, the command console 2A, the command console 2B, the base station group 4a, the base station group 4b, and the base station group 4c. 【0040】 Furthermore, the central device 1 can communicate with the public wireless terminal 9 via the ground communication control device 11 and the ground public wireless network 8. In other words, the central device 1 can communicate with the public wireless terminal 9. 【0041】 The onboard communication control device 10 is a control device that controls the devices installed on the train MV1. The onboard communication control device 10 can communicate with the train radio mobile station 7, the public radio terminal 9, and the passenger compartment communication terminal 14. 【0042】 The onboard communication control device 10 performs processing using the private train wireless communication system network N1 and the terrestrial public wireless network 8. The onboard communication control device 10 can communicate with the ground communication control device 11 via the public wireless terminal 9 and the terrestrial public wireless network 8. 【0043】 The onboard communication control device 10 and the ground communication control device 11 communicate with each other, thereby connecting the private train wireless communication network N1 and the public wireless communication network N2. 【0044】 When train MV1 is located on line A, which corresponds to base station group 4a and base station group 4b, train MV1 can communicate with the control console 2A responsible for line A. When train MV1 is located on line B, which corresponds to base station group 4c, train MV1 can communicate with the control console 2B responsible for line B. 【0045】 (On-board communication control device) Next, the configuration of the on-board communication control device 10 will be described. Figure 2 is a block diagram showing the configuration of the on-board communication control device 10 according to Embodiment 1. As shown in Figure 2, the on-board communication control device 10 includes a line information receiving unit 15, a terminal control unit 16, a location list unit 17, and a call detection unit 18. 【0046】 The line information receiving unit 15 can communicate with the train radio mobile station 7. The terminal control unit 16 can communicate with the public radio terminal 9. The terminal control unit 16 is a processing unit or processing circuit that performs characteristic processing described later. The call detection unit 18 can communicate with the passenger compartment telephone terminal 14. 【0047】 The location list section 17 has command console destination management information Tb1 pre-stored in it. Figure 3 shows an example of command console destination management information Tb1. The command console destination management information Tb1 in Figure 3 is represented, for example, as a table. Hereafter, the destination of the command console 2 will also be referred to as the "command console destination". The command console destination is, for example, an IP address. In the command console destination management information Tb1, the line section and the command console destination are shown linked together. 【0048】 In Figure 3, "Destination" refers to the destination of the command console. In Figure 3, the destination of the command console for line section A, which is command console 2A, is, for example, "XXXXXXXXX". 【0049】 In the command console destination management information Tb1, line A is linked to the destination "XXXXXXXXX" of command console 2A, which is the command console for line A. Similarly, line B is linked to the destination "YYYYYYYYY" of command console 2B, which is the command console for line B. In other words, the command console destination management information Tb1 indicates the destination "XXXXXXXXX" of command console 2A and the destination "YYYYYYYYY" of command console 2B. 【0050】 (Ground communication control device) Next, the configuration of the ground communication control device 11 will be described. Figure 4 is a block diagram showing the configuration of the ground communication control device 11 according to Embodiment 1. As shown in Figure 4, the ground communication control device 11 includes a connection request receiving unit 19 and a command operation console selection unit 20. 【0051】 The connection request receiving unit 19 can communicate with the terrestrial public wireless network 8. The command console selection unit 20 can communicate with the private train wireless communication system network N1. Specifically, the command console selection unit 20 can communicate with the central unit 1, the command console 2A, and the command console 2B. 【0052】 (operation) Next, the operation of the mobile communication system 1000 will be described. Specifically, Figures 1 and 5 will be used to describe the processes performed in the mobile communication system 1000 (hereinafter also referred to as "communication path establishment control processes"). 【0053】 In the following, the communication path for the cabin communication terminal 14 to communicate with the target control console via the terrestrial public radio network 8 will also be referred to as the "target communication path." The target communication path is the communication path from the cabin communication terminal 14 to the target control console. The target communication path is, for example, the path that passes through the onboard communication control device 10, the public radio terminal 9, the terrestrial public radio network 8, and the terrestrial communication control device 11. The communication path establishment control process is the process for establishing the target communication path. 【0054】 Figure 5 is a sequence diagram of the communication path establishment control process according to Embodiment 1. To make an example of the communication path establishment control process easier to understand, the communication path establishment control process performed under the following premise Pm1 will be described. 【0055】 In premise Pm1, train MV1 is located in line A, which corresponds to the base station group 4a that constitutes line A zone a. Also in premise Pm1, train MV1 is in operation. Also in premise Pm1, the target control console is control console 2A. Therefore, in premise Pm1, the target communication path is the communication path from the passenger communication terminal 14 to the target control console, control console 2A. 【0056】 Furthermore, under premise Pm1, train radio base station K4, which is included in base station group 4a corresponding to line section A, periodically transmits line section information indicating line section A to line section A. Therefore, under premise Pm1, when train MV1 is located in line section A, the train radio mobile station 7 of train MV1 periodically receives line section information indicating line section A. 【0057】 The relevant line information is train information Jt. Train radio base station K4, which is included in base station group 4a, is included in the private train radio communication system network N1. Therefore, the line information, which is train information Jt, is information obtained from the private train radio communication system network N1. 【0058】 Furthermore, in premise Pm1, the train radio mobile station 7 transmits line section information indicating line section A to the line section information receiving unit 15 of the onboard communication control device 10 each time it receives such line section information indicating line section A. The line section information receiving unit 15 transmits such line section information to the terminal control unit 16 each time it receives such line section information indicating line section A. In other words, in premise Pm1, the terminal control unit 16 of the onboard communication control device 10 receives line section information indicating line section A. The line section information received by the terminal control unit 16 is train information Jt obtained from the private train radio communication system network N1. Also, in premise Pm1, the terminal control unit 16 receives line section information indicating line section A as train information Jt before the selection process of step S110 described later is performed. 【0059】 Furthermore, in premise Pm1, the command console destination management information Tb1 shown in Figure 3 is pre-stored in the occupancy location list section 17. The command console destination management information Tb1 in Figure 3 indicates the destination "XXXXXXXXX" for command console 2A and the destination "YYYYYYYYY" for command console 2B. 【0060】 Furthermore, in premise Pm1, operator 12 is operating the command console 2A. 【0061】 The communication path establishment control process in the above premise Pm1 will now be explained. In the communication path establishment control process in premise Pm1, first, passenger 13 performs a call operation (step S101). The call operation is an operation to communicate with operator 12 who is operating the control console using the cabin communication terminal 14. 【0062】 When a call operation is performed, the passenger compartment communication terminal 14 outputs a call request to the onboard communication control device 10 (step S102). When the call detection unit 18 of the onboard communication control device 10 detects a call request, it notifies the terminal control unit 16 that a call request has been made. 【0063】 When the terminal control unit 16 of the on-board communication control device 10 receives notification of a call request, a selection process is performed (step S110). 【0064】 In the selection process in premise Pm1, to summarize, the terminal control unit 16 of the onboard communication control device 10 selects the target command control console 2A from among the command control consoles 2A and 2B based on the line information, which is the train information Jt, obtained from the private train wireless communication system network N1. In other words, the onboard communication control device 10 performs processing targeting multiple command control consoles 2. 【0065】 As mentioned above, in premise Pm1, the terminal control unit 16 of the onboard communication control device 10 receives line section information indicating line section A as train information Jt obtained from the private train radio communication system network N1 before the selection process in step S110 is performed. Also, as mentioned above, in premise Pm1, the command console destination management information Tb1 shown in Figure 3 is pre-stored in the occupancy location list unit 17. 【0066】 Specifically, in the selection process in premise Pm1, the terminal control unit 16 selects and obtains the destination "XXXXXXXXX" for command control console 2A, which is associated with line A indicated by the received line information, from the destination management information Tb1 of command control consoles 2A and 2B, among the destinations of command control consoles 2A and 2B. In other words, the terminal control unit 16 selects the target command control console, command control console 2A, based on the line information, which is the train information Jt obtained from the private train wireless communication system network N1. 【0067】 Next, the terminal control unit 16 of the on-board communication control device 10 outputs a connection request R1 to the public wireless terminal 9 (step S111). That is, the on-board communication control device 10 outputs a connection request R1 to the public wireless terminal 9. 【0068】 Connection request R1 is a request to establish a target communication path. In other words, connection request R1 is a connection request to the command console 2A. Connection request R1 indicates that the communication destination of the guest room call terminal 14 is the command console 2A. Specifically, connection request R1 indicates the destination "XXXXXXXXX" on the command console 2A. 【0069】 Next, the public radio terminal 9, upon receiving the connection request R1, outputs the connection request R1 to the ground communication control device 11 via the ground public radio network 8 (step S112). When the connection request receiving unit 19 of the ground communication control device 11 receives the connection request R1, it notifies the command console selection unit 20 that the connection request R1 has been issued. In other words, the connection request receiving unit 19 notifies the command console selection unit 20 of the connection request R1. 【0070】 The command console selection unit 20 of the ground communication control device 11 outputs a connection request R2 to the central device 1 in response to a notification from the connection request receiving unit 19 (step S113). The connection request R2 indicates that the communication destination of the cabin call terminal 14 is the command console 2A. Specifically, the connection request R2 indicates the destination "XXXXXXXXX" of the command console 2A. The connection request R2 also indicates that a connection request has been made from the public radio terminal 9 to the command console 2A. Furthermore, the connection request R2 is a request to establish the target communication path. 【0071】 In response to receiving the connection request R2, the central unit 1 outputs an incoming call request to the command console 2A for line section A (step S114). As a result, the operator 12 operating the command console 2A becomes aware that there is an incoming call request to the command console 2A. Therefore, the operator 12 performs an authorization operation to the command console 2A. This authorization operation permits the establishment of the target communication path, which is the communication path from the cabin intercom terminal 14 to the command console 2A. The authorization operation is performed, for example, using a mouse, keyboard, etc. 【0072】 Next, the command console 2A transmits a connection permission response to the onboard communication control device 10 via the central unit 1, the ground communication control device 11, the ground public radio network 8, and the public radio terminal 9 (step S120). The connection permission response is a response that permits the establishment of a target communication path, which is a communication path from the passenger compartment communication terminal 14 to the command console 2A, which is the target command console. 【0073】 As a result, the terminal control unit 16 of the on-board communication control device 10 receives a connection permission response. In response to receiving the connection permission response, the terminal control unit 16 performs call initiation control on the public radio terminal 9 (step S121). This call initiation control is a control that causes the public radio terminal 9 to initiate a call to the command console 2A via the terrestrial public radio network 8 and the terrestrial communication control device 11. 【0074】 The public radio terminal 9 makes a call to the command console 2A via the terrestrial public radio network 8 and the terrestrial communication control device 11, in accordance with the call initiation control. In other words, the public radio terminal 9 uses the terrestrial public radio network 8 to perform processing to establish a target communication path, which is a communication path from the cabin communication terminal 14 to the target command console 2A. 【0075】 This establishes a target communication path, which is a communication path from the cabin communication terminal 14 to the target control console 2A. This target communication path is a communication path for the cabin communication terminal 14 to communicate with the target control console 2A via the terrestrial public radio network 8. 【0076】 As described above, the communication path establishment control process in premise Pm1 is performed. In the communication path establishment control process in premise Pm1, the on-board communication control device 10 outputs a connection request R1 to the public wireless terminal 9, thereby performing steps S112, S113, S114, S120, and S121, and establishing the target communication path. That is, the on-board communication control device 10, which is a control device, performs the process of outputting a connection request R1 to the public wireless terminal 9 as a process for establishing the target communication path. 【0077】 Furthermore, the connection request R1 is output by the terminal control unit 16. That is, the terminal control unit 16 of the on-board communication control device 10 performs the process of outputting the connection request R1 to the public wireless terminal 9 as a process for establishing the target communication path. 【0078】 (summary) As described above, according to this embodiment, the onboard communication control device 10, which is a control device, selects a target command control console, which is command control console 2A, from among the command control consoles 2A and 2B, that is in charge of the line section where train MV1 is located, based on the line section information, which is train information, obtained from the private train radio communication system network N1. The onboard communication control device 10, which is a control device, performs processing to establish a target communication path, which is a communication path for the passenger compartment communication terminal 14 to communicate with the target command control console via the terrestrial public radio network 8. 【0079】 This allows cabin communication terminals to communicate with multiple control consoles using a public wireless network, which is beneficial in situations involving multiple control consoles. 【0080】 Furthermore, according to this embodiment, the onboard communication control device 10 selects a target command console based on line section information obtained from the private train radio communication system network N1. Specifically, the onboard communication control device 10 selects the destination of the target command console based on the line section information. The onboard communication control device 10 outputs a connection request R1 to the public radio terminal 9 to establish the target communication path. The public radio terminal 9 uses the terrestrial public radio network 8 to perform processing to establish the target communication path, which is the communication path from the passenger compartment communication terminal 14 to the target command console. 【0081】 This has the effect of establishing a target communication path, which is a communication path from the passenger compartment communication terminal 14 to the target control console, based on the line information, which is train information obtained from the private train wireless communication system network N1. 【0082】 By the way, in a narrowband private wireless communication network, the wireless communication bandwidth is limited. Therefore, increasing the number of new communication lines is not easy. For example, in a system employing FDMA (Frequency Division Multiple Access), it is necessary to add new frequency bands. Also, in a system employing TDMA (Time Division Multiple Access), it is necessary to add time slots. 【0083】 Therefore, when adding new communication lines to a system that already has a private wireless communication network, utilizing the public wireless network provided by a telecommunications carrier is an effective method. 【0084】 In railway operations, when a passenger boarding station requests a connection to a control panel, the call center must connect to the control center responsible for the line where the train is located. However, when using a public wireless network, identifying the destination control center responsible for the line where the train is located becomes a challenge. 【0085】 Furthermore, in the aforementioned related configuration A, which establishes a communication path based on the train's location, there are challenges such as the need to establish a method for obtaining the train's location and to install a call switching server. 【0086】 Therefore, the mobile communication system 1000 of this embodiment has a configuration that achieves the above-mentioned effects. As a result, the mobile communication system 1000 of this embodiment can solve the above-mentioned problems. 【0087】 For example, according to this embodiment, the private train radio communication system network N1 notifies the train radio mobile station 7 of train MV1 from the train radio network, which is a ground facility. When a line connection request is made from the passenger compartment communication terminal 14 to the control console 2, a line connection is made to the control console 2 responsible for the line where the train is located, based on the line section information, using the public radio network provided by the telecommunications carrier. 【0088】 This overcomes the challenge of the limited number of call lines in a private network while establishing a communication path from the cabin call terminal to the control console. Therefore, the mobile communication system 1000 of this embodiment can solve the above-mentioned problems. 【0089】 In this embodiment, an authorization operation and a connection authorization response were required to establish the target communication path, but a configuration that does not require an authorization operation and a connection authorization response is also possible. In such a configuration, for example, the target communication path may be established when the central device 1 outputs an incoming request to the command console 2A. 【0090】 Furthermore, the configuration of the mobile communication system 1000 is not limited to the configuration shown in Figure 1. For example, the terrestrial communication control device 11 and the central device 1 in the mobile communication system 1000 may be replaced with a call control device capable of communicating with the terrestrial public radio network 8. This call control device is a device that has the functions of the terrestrial communication control device 11 and the central device 1. 【0091】 Alternatively, the command console 2 may be configured to have the functions of both the ground communication control device 11 and the central device 1. In this configuration, the mobile communication system 1000 does not require the ground communication control device 11 or the central device 1. 【0092】 <Embodiment 2> (composition) Figure 6 shows the configuration of the mobile communication system 1000A according to Embodiment 2. The mobile communication system 1000A differs from the mobile communication system 1000 in Figure 1 mainly in that it is equipped with an on-board communication control device 10A instead of an on-board communication control device 10. The other configurations of the mobile communication system 1000A are the same as those of the mobile communication system 1000 in Figure 1, so a detailed explanation will not be repeated. The on-board communication control device 10A is mounted on the train MV1. 【0093】 (On-board communication control device) Next, the configuration of the on-board communication control device 10A will be described. Figure 7 is a block diagram showing the configuration of the on-board communication control device 10A according to Embodiment 2. The on-board communication control device 10A differs from the on-board communication control device 10 in Figure 2 in that it includes a train number receiving unit 21 instead of a line information receiving unit 15, and does not include a track location list unit 17. The other configurations of the on-board communication control device 10A are the same as those of the on-board communication control device 10 in Figure 2, so a detailed explanation will not be repeated. 【0094】 The onboard communication control device 10A can communicate with the train radio mobile station 7, the public radio terminal 9, and the passenger compartment communication terminal 14. The onboard communication control device 10A is a control device. 【0095】 The train number receiving unit 21 can communicate with the train radio mobile station 7. The terminal control unit 16 can communicate with the public radio terminal 9. The call detection unit 18 can communicate with the passenger compartment telephone terminal 14. 【0096】 The train radio mobile station 7 of this embodiment stores the set train number. The train number is train identification information that identifies a train. The train number is represented by, for example, numbers, symbols, etc. The train number may also be represented by, for example, a combination of numbers and symbols. 【0097】 A train number is assigned to each train. Each train is assigned a different train number. Train numbers are also used, for example, in railway timetables. In this embodiment, the train number is the train number assigned to train MV1. That is, the train number is train identification information that identifies train MV1. When train MV1 is in operation, the train number is train information Jt. That is, when train MV1 is in operation, the private train radio communication system network N1, including the train radio mobile station 7, is aware of the train information Jt. 【0098】 The train number is set, for example, by a train number setting operation to the train radio mobile station 7. The train number setting operation is performed, for example, by manual input by the crew. Alternatively, the train number setting operation may be performed using an IC card. 【0099】 Furthermore, the train radio mobile station 7 of this embodiment performs train number notification processing A and train number notification processing B. Train number notification processing A is the process of notifying the central device 1 of the train number via the base station group 4. Train number notification processing A is performed periodically, for example, when a train number is set. Also, train number notification processing A is performed, for example, each time the setting of a train number is changed. 【0100】 Train number notification process B is the process of notifying the onboard communication control device 10A of the train number. The detailed processes of train number notification process A and train number notification process B will be described later. 【0101】 The train number receiving unit 21 of the onboard communication control device 10A has the function of receiving train numbers. 【0102】 The configuration of the ground communication control device 11 in this embodiment is the same as the configuration of the ground communication control device 11 in Figure 4. 【0103】 (central unit) Next, the configuration of the central device 1 will be described. Figure 8 is a block diagram showing the configuration of the central device 1 according to Embodiment 2. As shown in Figure 8, the central device 1 includes a command operation console selection unit 25, a connection request receiving unit 26, a train number list unit 24, a train number list creation unit 27, and a train number receiving unit 28. 【0104】 The command console selection unit 25 and the connection request receiving unit 26 can communicate with the ground communication control device 11, the command console 2A, and the command console 2B. The command console selection unit 25 is a processing unit or processing circuit that performs characteristic processing described later. 【0105】 The train number receiving unit 28 is capable of communicating with base station group 4a, base station group 4b, and base station group 4c. The train number receiving unit 28 has the function of receiving train numbers. 【0106】 The central device 1 stores base station information Tb2. The base station information Tb2 is stored in, for example, a memory (not shown) of the central device 1. The base station information Tb2 may also be stored in other components of the central device 1 (for example, the train number list creation unit 27). 【0107】 Figure 9 shows an example of base station information Tb2. Base station information Tb2 includes base station ID management information and command console destination management information. 【0108】 The base station ID management information indicates the base station IDs for each of the following zones: Zone Aa, Zone Ab, and Zone Ba. For example, the base station IDs "111, 112, 113" for Zone Aa are the base station IDs for base station group 4a that make up Zone Aa. 【0109】 In the base station ID management information, the base station IDs for line section A zone a and line section A zone b are linked to line section A. That is, the base station ID for base station group 4a is linked to line section A. Also, in the base station ID management information, the base station ID for line section B zone a is linked to line section B. 【0110】 The command console destination management information for base station information Tb2 is the same as the command console destination management information Tb1 in Figure 3. 【0111】 Referring again to Figure 8, the train number list unit 24 is, for example, a storage device such as memory. The train number list creation unit 27, as will be described in detail later, has the function of creating a management table Tb3 based on the train number and base station information Tb2. The created management table Tb3 is stored in the train number list unit 24. 【0112】 Figure 10 shows an example of the management table Tb3. In the management table Tb3, the train number, the line section, and the destination of the control console are linked and displayed. Details of the management table Tb3 will be described later. 【0113】 (operation) Next, the operation of the mobile communication system 1000A will be described. Specifically, Figures 6 and 11 will be used to explain the processing performed in the mobile communication system 1000A (hereinafter also referred to as "communication path establishment control processing A"). 【0114】 Figure 11 is a sequence diagram of the communication path establishment control process A according to Embodiment 2. To make an example of the communication path establishment control process A easier to understand, the communication path establishment control process A performed under the following premise Pm2 will be described. 【0115】 In premise Pm2, train MV1 is located in line A, which corresponds to the base station group 4a that constitutes line A zone a. Also in premise Pm2, train MV1 is in operation. Furthermore, in premise Pm2, the target control console is control console 2A. Therefore, in premise Pm2, the target communication path is the communication path from the passenger communication terminal 14 to the target control console, control console 2A. 【0116】 Furthermore, under premise Pm2, the train radio mobile station 7 performs the aforementioned train number notification process A and train number notification process B. As mentioned above, train number notification process A is the process of notifying the central device 1 of the train number via the base station group 4. Under premise Pm2, the train number is, for example, "11111111". 【0117】 In premise Pm2, train number notification process A is performed before communication route establishment control process A is performed. Also, in premise Pm2, the management table creation process described later is performed before communication route establishment control process A is performed. 【0118】 Here, we will explain the train number notification process A and the management table creation process in premise Pm2. In train number notification process A in premise Pm2, the train radio mobile station 7 transmits the train number "11111111" to the train radio base station K4 of base station group 4a corresponding to line section A where train MV1 is located. The train radio base station K4 of base station group 4a transmits the train number "11111111" and the base station IDs of base station group 4a "111,112,113" to the central device 1. 【0119】 As a result, the train number receiving unit 28 of the central device 1 receives the train number "11111111" and the base station IDs "111,112,113". The train number receiving unit 28 transmits the train number "11111111" and the base station IDs "111,112,113" to the train number list creation unit 27. 【0120】 Next, the management table creation process in Premise Pm2 is performed. In the management table creation process in Premise Pm2, the train number list creation unit 27 obtains the base station ID management information of base station information Tb2 in Figure 9. The train number list creation unit 27 identifies line section A associated with the received base station IDs "111, 112, 113" in the base station ID management information of the base station information Tb2. The identified line section A is the line where train MV1 is located. 【0121】 Next, the train number list creation unit 27 identifies the destination "XXXXXXXXX" of the command console 2A, which is associated with line section A, in the command console destination management information of the base station information Tb2. 【0122】 The train number list creation unit 27 links the train number with the identified information described above. Specifically, the train number list creation unit 27 links the train number "11111111" with line section A and the destination "XXXXXXXXX" on the control console 2A. 【0123】 As a result, the train number list creation unit 27 creates the management table Tb3. The created management table Tb3 is a table that shows the information of the first row of the management table Tb3 in Figure 10. The train number list creation unit 27 stores the created management table Tb3 in the train number list unit 24. 【0124】 Whenever the central device 1 receives a train number that is not listed in the management table Tb3 stored in the train number list section 24, it updates the management table Tb3 using a process similar to the management table creation process described above. The updated management table Tb3 is, for example, the management table Tb3 in Figure 10. 【0125】 In Premise Pm2, the above process is performed, and before the communication path establishment control process A is performed, the management table Tb3 shown in Figure 10 is stored in the train number list section 24. 【0126】 Furthermore, in Premise Pm2, train number notification process B is performed before communication path establishment control process A is performed. As mentioned above, train number notification process B is the process of notifying the onboard communication control device 10A of the train number. The train number is train information Jt, which is information about the train MV1 in operation. In Premise Pm2, the train number is, for example, "11111111". 【0127】 Train number notification process B is performed periodically, for example. In train number notification process B under premise Pm2, the train radio mobile station 7 transmits the train number to the on-board communication control device 10A. Therefore, under premise Pm2, the train number receiving unit 21 of the on-board communication control device 10A receives the train number from the train radio mobile station 7. The train radio mobile station 7 is included in the private train radio communication system network N1. Thus, under premise Pm2, the train number, which is the train information Jt received by the on-board communication control device 10A, is information obtained from the private train radio communication system network N1. Also, under premise Pm2, the train number receiving unit 21 receives the train number as train information Jt before step S111A, described later, is performed. 【0128】 Furthermore, in premise Pm2, operator 12 is operating the command console 2A. 【0129】 The communication path establishment control process A in the above-mentioned premise Pm2 will be explained using Figures 6 and 11. In Figure 11, the process with the same step number as in Figure 5 is the same as the process described in Embodiment 1. The differences from Embodiment 1 will be explained below. 【0130】 In the communication path establishment control process A in premise Pm2, first, passenger 13 performs a call operation (step S101). The call operation is an operation to communicate with operator 12 who is operating the control console using the cabin communication terminal 14. 【0131】 When a call operation is performed, the passenger compartment communication terminal 14 outputs a call request to the onboard communication control device 10A (step S102A). When the call detection unit 18 of the onboard communication control device 10A detects a call request, it notifies the terminal control unit 16 that a call request has been made. 【0132】 When the terminal control unit 16 of the onboard communication control device 10A receives notification of a call request, the terminal control unit 16 adds the train number "11111111" received by the train number receiving unit 21 through the aforementioned train number notification process B to the connection request R1a. As mentioned above, in premise Pm2, the train number, which is the train information Jt received by the onboard communication control device 10A, is information obtained from the private train wireless communication system network N1. That is, the train number "11111111" is information obtained from the private train wireless communication system network N1. 【0133】 The terminal control unit 16 outputs a connection request R1a with the train number added to it to the public radio terminal 9 (step S111A). The connection request R1a is a connection request to establish the target communication path. In other words, the connection request R1a is a connection request to the command console 2A. 【0134】 Next, the public radio terminal 9, upon receiving the connection request R1a, outputs the connection request R1a to the ground communication control device 11 via the ground public radio network 8 (step S112A). When the connection request receiving unit 19 of the ground communication control device 11 receives the connection request R1a, it notifies the command console selection unit 20 that the connection request R1a has been issued. In other words, the connection request receiving unit 19 notifies the command console selection unit 20 of the connection request R1a. 【0135】 The command console selection unit 20 of the ground communication control device 11 outputs connection request R2a to the central device 1 in response to a notification from the connection request receiving unit 19 (step S113A). Connection request R2a is a request to establish the target communication path. Connection request R2a also indicates that a connection request has been made to the command console 2A from the public radio terminal 9. In addition, the train number "11111111" from connection request R1a is appended to connection request R2a. This train number "11111111" is train information Jt obtained from the private train radio communication system network N1. 【0136】 Next, the connection request receiving unit 26 of the central device 1 receives a connection request R2a with the train number "11111111" added to it. The connection request receiving unit 26 notifies the command console selection unit 25 of the train number "11111111". The train number "11111111" is train information Jt obtained from the private train radio communication system network N1. Then, selection process A is performed (step S113B). 【0137】 In the selection process A in premise Pm2, to summarize, the command console selection unit 25 of the central device 1 selects command console 2A from among command consoles 2A and 2B, based on the train number, which is the train information Jt obtained from the private train wireless communication system network N1. In other words, the central device 1 performs processing targeting multiple command consoles 2. The train number is train identification information that identifies the train. 【0138】 As mentioned above, in premise Pm2, the management table Tb3 shown in Figure 10 is stored in the train number list section 24 before the communication path establishment control process A is performed. 【0139】 Specifically, in the selection process A in premise Pm2, the command console selection unit 25 selects and obtains the destination "XXXXXXXXX" for command console 2A, which is associated with the notified train number "11111111" from the destinations of command consoles 2A and 2B in the management table Tb3 of Figure 10 stored in the train number list unit 24. The train number "11111111" is train information Jt obtained from the private train radio communication system network N1. In other words, the command console selection unit 25 selects the target command console, command console 2A, based on the train number, which is train information Jt obtained from the private train radio communication system network N1. 【0140】 Next, the central device 1 outputs an incoming call request to the command console 2A for line section A, which corresponds to the selected destination "XXXXXXXXX" (step S114A). As a result, the operator 12 operating the command console 2A becomes aware that there is an incoming call request to the command console 2A. Therefore, the operator 12 performs an authorization operation to the command console 2A, similar to the first embodiment. 【0141】 Next, the command console 2A transmits a connection permission response to the onboard communication control device 10A via the central unit 1, the ground communication control device 11, the ground public radio network 8, and the public radio terminal 9 (step S120A). The connection permission response is a response that permits the establishment of a target communication path, which is a communication path from the passenger compartment communication terminal 14 to the command console 2A, which is the target command console. 【0142】 As a result, the terminal control unit 16 of the on-board communication control device 10A receives a connection permission response. In response to receiving the connection permission response, the terminal control unit 16 performs call initiation control on the public wireless terminal 9, similar to the first embodiment (step S121). This call initiation control is a control that causes the public wireless terminal 9 to initiate a call to the command console 2A via the terrestrial public wireless network 8 and the terrestrial communication control device 11. 【0143】 The public radio terminal 9 makes a call to the command console 2A via the terrestrial public radio network 8 and the terrestrial communication control device 11, in accordance with the call initiation control. In other words, the public radio terminal 9 uses the terrestrial public radio network 8 to perform processing to establish a target communication path, which is a communication path from the cabin communication terminal 14 to the target command console 2A. 【0144】 This establishes a target communication path, which is a communication path from the cabin communication terminal 14 to the target control console 2A. This target communication path is a communication path for the cabin communication terminal 14 to communicate with the target control console 2A via the terrestrial public radio network 8. 【0145】 As described above, the communication path establishment control process A in premise Pm2 is performed. In the communication path establishment control process A in premise Pm2, the public wireless terminal 9 outputs a connection request R1a, which triggers steps S113A, S113B, S114A, S120A, and S121, and the target communication path is established. 【0146】 In step S114A described above, the central device 1 outputs an incoming call request to the command console 2A for line section A. That is, the central device 1, which is a control device, performs the process of outputting an incoming call request to the command console 2A as a process for establishing the target communication path. 【0147】 The process in step S114A described above is performed when a connection request R1a is issued from the public wireless terminal 9. That is, when the control unit, the central device 1, receives a connection request R1a from the public wireless terminal 9, it performs the process of outputting an incoming call request to the command console 2A as a process to establish the target communication path. 【0148】 (summary) As described above, according to this embodiment, the command console selection unit 25 of the central device 1 selects the command console 2A from among the command consoles 2A and 2B, which is the target command console, based on the train number, which is the train information Jt obtained from the private train wireless communication system network N1. The central device 1, which is the control device, performs a process to output an incoming call request to the command console 2A as a process to establish the target communication path. 【0149】 This provides the advantage that, in situations involving multiple control consoles, the in-room communication terminal can communicate with the control console using a public wireless network. In other words, this embodiment provides the same advantages as the first embodiment. 【0150】 Therefore, for example, it is possible to overcome the challenge of the number of communication lines in a private network and establish a communication path from the passenger compartment communication terminal 14 to the target control console based on the train number, which is train information obtained from the private train wireless communication system network N1. 【0151】 In this embodiment, the train radio mobile station 7 stores the train number, and the train number receiving unit 21 of the onboard communication control device 10A acquires the train number from the train radio mobile station 7. However, this is not limited to this. The train number receiving unit 21 of the onboard communication control device 10A may acquire the train number from, for example, a monitoring device that manages information on railway vehicles. 【0152】 In this embodiment, an authorization operation and a connection authorization response were required to establish the target communication path, but a configuration that does not require an authorization operation and a connection authorization response is also possible. In such a configuration, for example, the target communication path may be established when the central device 1 outputs an incoming request to the command console 2A. 【0153】 (Example of mobile communication system hardware configuration) Hereinafter, the mobile communication system related to this technology will also be referred to as "mobile communication system Hs1". Mobile communication system Hs1 is either mobile communication system 1000 or mobile communication system 1000A. Furthermore, hereafter, the main functions related to this technology that mobile communication system Hs1 possesses will also be referred to as "main functions". Mobile communication system Hs1 has main functions. 【0154】 Figures 12 and 13 show examples of the hardware configuration of the mobile communication system Hs1. The main functions of the mobile communication system Hs1 are realized, for example, by a single processing circuit 70, as shown in Figure 12. 【0155】 The processing circuit 70 selects a target command control console from among several command control consoles, which is the command control console responsible for the railway line where the train is located, based on train information obtained from the private train wireless communication system network. 【0156】 Furthermore, the processing circuit 70 performs processing to establish a target communication path, which is a communication path for the guest room call terminal to communicate with the target command console via the public wireless network. 【0157】 The processing circuit 70 may be dedicated hardware. Alternatively, the processing circuit 70 may be configured using a processor that executes a program stored in memory. Such a processor may be, for example, a CPU (Central Processing Unit), a central processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP (Digital Signal Processor). 【0158】 In the following, the situation in which the processing circuit 70 is dedicated hardware will also be referred to as "Situation St1". Furthermore, in the following, the situation in which the processing circuit 70 is configured using a processor will also be referred to as "Situation St2". 【0159】 In situation St1, the processing circuit 70 may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof. 【0160】 Figure 13 shows an example of the hardware configuration of the mobile communication system Hs1 in situation St2, where the processing circuit 70 is configured using a processor. The configuration in Figure 13 is a configuration in which the processing circuit 70 of Figure 12 is realized with a processor 71 and memory 72. 【0161】 In scenario St2, the main functions of the mobile communication system Hs1 are implemented by software A. Software A is either software or firmware. Alternatively, software A may consist of a combination of software and firmware. Software A is written as a program and stored in memory 72. 【0162】 Furthermore, in situation St2, the processor 71 reads the program stored in memory 72 and executes it, thereby realizing the main functions of the mobile communication system Hs1. Specifically, memory 72 stores the following program: 【0163】 This program causes the processor 71 to perform the process of selecting a target control console, which is the control console responsible for the railway line where the train is located, from among several control consoles, based on train information obtained from the private train radio communication system network. 【0164】 Furthermore, this program also causes the processor 71 to execute a process to establish a target communication path, which is a communication path for the cabin call terminal to communicate with the target control console via the public wireless network. 【0165】 Furthermore, this program also causes a computer to execute the processes performed by the main functions of the mobile communication system Hs1, as well as the methods for executing those processes. 【0166】 Here, memory 72 is a non-volatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM, or EEPROM. Alternatively, memory 72 may be a magnetic disk, flexible disk, optical disk, compact disk, minidisc, DVD, etc. Furthermore, memory 72 may be any storage medium used in the future. 【0167】 As described above, the mobile communication system Hs1 can implement each of the above-mentioned functions by hardware or software A. 【0168】 Furthermore, this technology may be implemented as a communication path establishment control method that uses the operation of characteristic components of the mobile communication system Hs1 as steps. Alternatively, this technology may be implemented as a program that causes a computer to execute each step included in such a communication path establishment control method. 【0169】 Furthermore, this technology may be implemented as a computer-readable recording medium for storing such a program. The program may also be distributed via a transmission medium such as the Internet. The communication path establishment control method related to this technology corresponds, for example, to the communication path establishment control process of Embodiment 1, or to the communication path establishment control process A of Embodiment 2. 【0170】 (Other variations) Furthermore, it is possible to freely combine each embodiment, or to modify or omit each embodiment as appropriate. 【0171】 For example, the mobile communication system 1000 or mobile communication system 1000A does not have to include all the components shown in the figure. That is, the mobile communication system 1000 or mobile communication system 1000A only needs to include the minimum components necessary to realize the effects of this technology. 【0172】 The various aspects of this disclosure are summarized below as an appendix. 【0173】 (Note 1) A mobile communication system that performs processing using a privately operated train radio communication network, which is a privately operated train radio system, and a public radio network provided by a telecommunications carrier, The aforementioned privately operated train radio communication system network obtains train information, which is information about trains in operation.
