Description

  The present invention relates to a network resource reservation method, access providing system, network resource reservation program, and recording medium using user movement information.

A system for reserving the network bandwidth before using the network has been proposed (for example, Patent Document 1). As a result, the communication terminal that has previously reserved the bandwidth can immediately utilize the reserved bandwidth when the network is connected. Therefore, after connecting the communication terminal to the network, it is possible to prevent a situation in which the bandwidth of the network cannot be secured, and the communication use of the communication terminal can be performed smoothly.
JP 2001-177555 A (paragraph [0010])

  Here, when reserving the network resource before using the network, it can be classified into a method utilizing a communication terminal utilization schedule known in advance and a method utilizing no utilization schedule.

  First, the method of utilizing the communication terminal utilization schedule performs the network resource reservation process according to the utilization schedule, so that there is no processing overhead such as wasteful reservation of unused network resources. And the use efficiency of communication lines is good. However, if there is a change in the usage schedule due to troubles (such as traffic jams) while the communication terminal is moving, the network resource reservation process based on the usage schedule before the change cannot be used, so it is vulnerable to changes in the usage schedule (or changes) Is not allowed).

  On the other hand, a method that does not use a communication terminal utilization schedule (for example, Patent Document 1) predicts the behavior of a communication terminal and reserves network resources that will be used. Therefore, when the prediction is wrong, the unused network resources are reserved unnecessarily, so that the processing efficiency is poor and the communication line utilization efficiency is also deteriorated. In addition, since the technique described in Patent Document 1 predicts the behavior of a communication terminal based on the position information of the communication terminal, the network to be used becomes known immediately before use. Therefore, network bandwidth reservation is performed immediately before use, so that the use of the communication terminal is kept waiting until the bandwidth reservation is completed. However, the method that does not use the use schedule is resistant to environmental fluctuations because the network resource reservation process is not affected by troubles (such as traffic congestion) during movement of the communication terminal.

  As described above, the method of using the use schedule and the method of not using the use have different advantages and disadvantages, and which method is used depends on the user's selection. Therefore, it takes a great deal of time and effort for the user to consider which method to select, which is a burden on the user.

  Hereinafter, an embodiment of an access providing system to which the present invention is applied will be described in detail with reference to the drawings. First, the configuration of the access providing system of this embodiment will be described with reference to FIGS. 1 and 2.

  FIG. 1 is a configuration diagram of an access providing system. The access providing system has a function of reserving resources of the network 40 before the communication terminal 11 uses the network 40. And an access provision system presupposes that the communication terminal 11 moves with the mobile body 12 which is transportation, such as a train. Furthermore, the access providing system includes a mobile operation management device 20 that manages the latest operation schedule of the mobile body 12 and a reservation agent device 30 that performs reservation of resources of the communication terminal 11. The access point 41 is a gateway device that serves as a contact when the communication terminal 11 uses the network 40.

  Here, the resources of the network 40 are resources related to the network for the network 40 to provide service quality such as the minimum communication speed of the line, the average delay time in the network, and the upper limit of the unavailable time. Further, the resources of the network 40 may include computer resources (arithmetic devices, memories, etc.) of communication devices that constitute the network 40.

  The network 40 is located at an accessible location from each planned arrival location of the mobile body 12. For example, FIG. 7A shows a first network that can be accessed from Tokyo Station, a second network that can be accessed from Nagoya Station, when each destination is a station (that is, the mobile body 12 is a train), Three examples of the third network accessible from Shin-Osaka Station are shown.

  Here, the operation schedule is information provided by a traffic system or the like that manages the operation of the moving body 12. For example, in the train schedule, a predetermined operation diagram is updated according to the current operation status. Even if an unforeseen situation such as a human accident occurs, the operation schedule is appropriately modified by the traffic system or the like in accordance with the situation (delay of arrival time, selection of detour, etc.). Therefore, the latest operation schedule is a schedule updated according to the current operation status.

  FIG. 2 is a block diagram illustrating in detail the device configuration of the access providing system. The mobile body operation management device 20 includes an operation schedule management means 21 that manages the operation schedule of the mobile body 12, an operation schedule update means 22 that updates the operation schedule of the mobile body, the ID of the mobile body, and And operation schedule acquisition means 23 for acquiring the operation schedule of the mobile object based on the usage information of the mobile object 12.

  The reservation agent device 30 receives movement information input means 31 for receiving input of movement information for specifying the communication terminal ID, the ID of the moving body, and the usage information of the moving body 12 including the use start point and the use end point. And a network specifying means 32 for specifying a device for managing the network of the planned arrival place of the mobile body 12 from the operation schedule, and a communication terminal ID corresponding to the staying period at the planned arrival place of the mobile body specified from the operation schedule A resource reservation unit 33 for reserving network resources of the communication terminal and an authentication unit 34 for authenticating the communication terminal corresponding to the ID of the communication terminal.

  Note that the ID of the mobile object is basically an ID for uniquely identifying a mobile object (such as a train) operated during a predetermined period of the operation schedule. Therefore, on the 10th March, the Shinkansen running from Tokyo Station (departing at 9am) to Shin-Osaka Station (arriving at 11am) and the same day from Shin-Osaka Station (departing at 11:20 am) to Nagoya ( The same vehicle (same hardware) that travels up to 0:20 pm) is the same as the Shinkansen, but it is a different vehicle (difference between up and down) on the operation schedule. The ID of the mobile body 12 to be assigned is different.

  Furthermore, a plurality of IDs may be assigned to one train as the ID of the moving object. This deals with a case where a predetermined moving body branches at a relay point between the start point and the end point. In that case, ID of a moving body shall be allocated to each of two trains divided after branching.

  The network 40 includes an access point 41 for allowing the communication terminal 11 to access the network 40, a network resource management device 42 for managing resources of the network 40, and a network authentication device 43 for authenticating a terminal accessing the network. Configured. The network resource management device 42 includes a reservation storage unit 42A that stores a resource reservation result of the network 40, and the network authentication device 43 includes an authentication storage unit 43A that stores a terminal authentication result.

  Here, the usage information for which the movement information input means 31 receives input includes the usage start point and the usage end point, because the passenger of the mobile body 12 is from the start point to the end point in the operation schedule of the mobile body 12. By reflecting the phenomenon that it does not necessarily get on the moving body 12 in all the routes. That is, it may be known in advance in the ticket reservation that the passenger of the moving body 12 gets into the moving body 12 only in a part of the route. In this case, the passenger of the moving body 12 The network resource reservation process in the section not riding on 12 is unnecessary. Therefore, by limiting the operation schedule used for the network resource reservation process to the section used by the passengers of the mobile body 12, it becomes possible to suppress the useless network resource reservation process.

  Note that the usage information for which the movement information input unit 31 receives input may be configured to include information for specifying a seat in the moving body 12. This is information for specifying which network 40 of the plurality of networks 40 is connected to the predetermined mobile body 12 in the form of connecting to the plurality of networks 40 at the same time. For example, when the moving body 12 is a 16-car train Shinkansen, the distance between the frontmost train (first car) of the Shinkansen and the rearmost car (16th car) is increased. Therefore, due to technical restrictions such as the reach of radio communication radio waves, one network 40 cannot make the entire Shinkansen vehicle communicable. In that case, one Shinkansen is configured to change the network 40 to be connected according to the position of the vehicle. Then, by using the information specifying the position of the seat, the network 40 to which the communication terminal 11 near the seat is connected is uniquely specified.

  The configuration of the access providing system has been described above. Next, the operation of the access providing system of this embodiment will be described with reference to FIGS. 3 and 4 with reference to FIGS. 1 and 2.

  FIG. 3 is a flowchart showing network reservation processing of the access providing system.

  First, the communication terminal 11 transmits movement information to the reservation agent device 30 (S101). Next, the reservation agent device 30 requests the mobile operation management device 20 for an operation schedule including the received movement information (S102). And the mobile body operation management apparatus 20 transmits the operation schedule acquired from movement information to the reservation agent apparatus 30 (S103).

  In addition, when the moving body operation management apparatus 20 acquires an operation schedule from movement information, the operation schedule acquisition means 23 respond | corresponds to the ID of the moving body from the operation schedule management means 21 by using ID of a moving body as a key. The operation schedule to be acquired is acquired (see FIG. 7B).

  Furthermore, the reservation agent device 30 identifies the destination network 40 from the operation schedule (S104). This is a process of searching for an available network from each planned arrival place in the operation schedule. Therefore, the reservation agent device 30 specifies the network 40 based on the network correspondence table as shown in FIG. The network correspondence table may be included in the reservation proxy device 30 itself, or may be included in another device.

  Then, the reservation agent device 30 requests the network authentication device 43 to authenticate the communication terminal 11 with respect to the destination network 40 (S105). Further, the network authentication device 43 transmits the authentication result of the communication terminal 11 to the reservation proxy device 30 (S106).

  Then, the reservation agent device 30 requests the network resource management device 42 to make a network resource reservation based on the authentication result of the communication terminal 11 (S107). Further, the network resource management device 42 transmits the network resource reservation result of the communication terminal 11 to the reservation proxy device 30 (S108).

  Then, the reservation agent device 30 notifies the communication terminal 11 of the result of the network reservation (S109).

  FIG. 4 is a flowchart illustrating a process related to a change in the operation schedule of the access providing system.

  First, the reservation agent device 30 notifies the mobile operation management device 20 of the changed operation schedule (S201). Next, the reservation agent device 30 requests the network resource management device 42 to make a network resource reservation based on the authentication result of the communication terminal 11 (S202). Then, the network resource management device 42 transmits the network resource reservation result of the communication terminal to the reservation proxy device 30 (S203). Furthermore, the reservation agent device 30 notifies the communication terminal 11 of the result of the network reservation (S204).

  The present invention described above can be widely modified without departing from the spirit of the invention as follows.

  For example, the access providing system may reallocate a part of the resources allocated to the terminal that has already reserved or used the network resource to the reservation of the communication terminal 11 performed this time. A specific example will be described below.

  FIG. 5 is an explanatory diagram relating to bandwidth reservation in the access providing system. FIG. 5A shows a state where three communications (communication 1, communications 2, and communications 3) have already been reserved, and FIG. 5B shows one communications (communication 4) in addition to the three communications. ) Indicates a newly reserved state. In FIG. 5, class A means communication to which a high-quality (for example, 100 Mbps) band is allocated, and class B refers to communication to which a low-quality (for example, 10 Mbps) band is allocated. Therefore, when reserving communication 4, if the remaining number of available communications of class A is insufficient, any communication that already uses class A (for example, communication 1) is demoted to class B. By doing so, it becomes possible to reserve the communication 4 with class A quality (see FIG. 5B).

  In the access providing system, the ticket reading device at the ticket gate that passes to arrive at the boarding / exiting location of the moving body 12 may accept the input of the movement information read from the ticket. FIG. 6 is a configuration diagram showing input of movement information through the ticket reading device 13 of the access providing system. Thereby, the reservation agent device 30 performs network authentication and resource reservation based on the movement information read from the ticket by the ticket reading device 13.

  Furthermore, the access providing system can target various mobile bodies as the mobile body 12 in addition to a train that stops at a station. For example, any vehicle with a diagram (operation table) such as an airplane landing at an airport, a ship anchored at a port, or a bus stopping at a stop can be used as a moving object.
