Description

  The present disclosure relates to a resource management apparatus, a resource management system, a resource management method, and a resource management program for resource management in a wide area wireless communication network.

  In recent years, with the widespread use of multifunctional terminals such as smartphones, resources such as memory required in base stations for providing services to individual mobile terminals have increased. For this reason, the supply of resources in a wide area wireless communication network has become tight, and it has become difficult to maintain the quality of service (QoS) for services provided to users via mobile terminals. ing.

  Under such circumstances, as a technique for guaranteeing QoS for a user, for example, information on a movement route of each user is received by provision from the user, and the resource is based on the provided information. Has been proposed (Patent Document 1). In addition, a technique has been proposed in which provision of information indicating the position of each user is periodically received and resource reservation is performed based on the provided information (Patent Document 2).

  By the way, the information provided from the user before the user starts moving may not reflect the actual movement of the user. In addition, since the information related to the user's travel route is personal information of the user, it is difficult to collect such information with the cooperation of the user.

  On the other hand, by receiving location information from each user's mobile terminal periodically, accurate location information can be obtained for each user. On the other hand, if the location information changes quickly, such as when the user is on a moving object such as a train or bus, it is not enough to reserve the resource after receiving the location information. there is a possibility. In addition, as in the case where the user provides information related to the travel route in advance, it is difficult for the user to obtain his / her position information sequentially to obtain user cooperation. Further, since communication for periodically providing location information is performed by consuming resources allocated to the user, the QoS for the service that the user is receiving via the mobile terminal is reduced. There is a fear.

By using information indicating the positions of a plurality of reference points included in the route database DB2 corresponding to the operation route R1, the operation route R1 can be approximated by a collection of straight lines connecting the reference points. Furthermore, the route database DB2 may include information on operation routes of various moving bodies that move in an area where a wireless communication service by a wide area wireless communication network is provided.

  FIG. 4 shows an example of the timetable database DB3 illustrated in FIG. 4 that are the same as those shown in FIG. 1, FIG. 2, or FIG. 3 are given the same reference numerals, and descriptions thereof are omitted.

  The timetable database DB3 illustrated in FIG. 4 shows a route ID indicating a route on which the moving object is operated and an end point of the operation of the moving object or a destination direction corresponding to the moving object ID indicating each moving object. Includes end / direction information. In addition, the timetable database DB3 further includes information indicating a plurality of stop stations included in a route on which each moving body is operated, and information indicating departure times corresponding to these stop stations.

  For example, the timetable database DB3 illustrated in FIG. 4 includes a route ID “R1” and destination / direction information “up” corresponding to the moving object ID “V1” indicating the moving object V1. Further, the timetable database DB3 includes station IDs indicating a plurality of stations including the stations S0, S1, and S2 as information indicating the stop station of the moving body V1. The timetable database DB3 includes information indicating departure times “04:30”, “04:33”, and “04:36” corresponding to each stop station of the moving body V1.

  Further, as shown in FIG. 4 corresponding to the moving body ID “V2” indicating another moving body V2, the timetable database DB3 can include timetable information regarding the operation of a plurality of moving bodies. In the example of FIG. 4, the timetable database DB3 includes a route ID “R2” and destination / direction information “up” corresponding to the moving object ID “V2” indicating the moving object V2. The timetable database DB3 includes station IDs indicating a plurality of stations including the stations S4 and S2 as information indicating the stop station of the moving body V2. The timetable database DB3 includes information indicating departure times “04:32” and “04:37” corresponding to each stop station of the moving object V2. In the following description, when the mobile bodies V1, V2 and other mobile bodies are generically referred to, they are simply referred to as the mobile body V.

  Based on the information accumulated in these databases, the prediction unit 12 illustrated in FIG. 1 first selects the mobile unit V1 included in the information collected by the collection unit 11 from the terminal device 1 mounted on the mobile unit V1. Based on the identification information shown, the operation route of this moving body V1 is specified.

  For example, the prediction unit 12 receives the moving body ID “V1” indicating the moving body V1 from the collection unit 11, and searches the timetable database DB3 based on the identification information “V1”, thereby operating the moving body V1. A route ID indicating the route may be acquired.

  By referring to the route database DB2 based on the route ID “R1” obtained in this way, the prediction unit 12 can determine the positions of the reference points provided in the stations included in the route R1 and in the sections delimited by the stations. Get information indicating

  And based on the information which shows the position of these stations and reference points, and base station database DB1, the prediction part 12 is the process in which the mobile body V1 moves according to service route R1, and each portable terminal UE in the mobile body V1. Identifies the base station BS to which the handover is sequentially performed.

  FIG. 5 is a diagram for explaining the relationship between the arrangement of the base stations BS and the operation route R1. Note that among the elements shown in FIG. 5, elements equivalent to those shown in FIGS. 1 to 4 are denoted by the same reference numerals and description thereof is omitted.

  The travel route R1 of the mobile unit V1 illustrated in FIG. 5 passes through cells corresponding to the base stations BS-B, BS-D, and BS-G in order after leaving the station S1.

  For example, the prediction unit 12 searches the base station database DB1 for the base station closest to each reference point acquired from the route database DB2 as described above, so that these base stations BS-B, BS-D. , BS-G may be specified. Similarly, the prediction unit 12 can sequentially identify each base station through which each mobile terminal UE in the mobile body V1 passes as the mobile body V1 operates.

  Furthermore, the prediction unit 12 uses the information accumulated in the base station database DB1 and the route database DB2, thereby allowing the cell boundary corresponding to each base station BS identified as described above and the route R1 of the mobile unit V1 to be determined. Each of the points where can intersect can be determined. For example, the prediction unit 12 obtains each intersection of the cell R indicated by the cell radius of each base station BS and the route R1 approximated by a broken line using the reference point indicated by the route database DB2, respectively. You may obtain | require the intersection of the boundary of each cell and path | route R1. Further, by obtaining the intersection of the ellipse indicating the boundary of the handover zone described with reference to FIG. 2 and the route R1 approximated by the broken line as described above, the intersection of each cell boundary and the route R1 is obtained. Also good. The intersection between the boundary of each cell thus obtained and the route R1 is a point where the mobile body V1 enters a cell corresponding to each base station BS, and for each mobile terminal UE in the mobile body V1, the cell This is a point at which the handover process to the base station BS corresponding to is started.

  For example, in each point indicated by reference characters PB1, PD1, and PG1 in FIG. 5, a process is started in which each mobile terminal UE in the mobile unit V1 is handed over to the base stations BS-B, BS-D, and BS-G, respectively. Indicates a handover point.

  The predicting unit 12 calculates the coordinates indicating the positions of these handover points PB1, PD1, and PG1 in the process of calculating the positions of the base stations BS-B, BS-D, and BS-G held in the base station database DB1. Information indicating the radius of the corresponding cell can be used. Similarly, the prediction unit 12 calculates the coordinates indicating the positions of these handover points PB1, PD1, and PG1 in the respective reference points P0, P1, P2,..., Pn−1 held in the route database DB2. , Pn can be used.

  Next, the prediction unit 12 moves the mobile object V1 to each handover point based on the position of each handover point, information indicating the operation schedule of the mobile object V1 included in the timetable database DB3, and the position of the mobile object V1. Calculate the time that is expected to arrive.

  For example, when calculating the predicted arrival time at each handover point PB1, PD1, PG1 illustrated in FIG. 5, the prediction unit 12 can use the departure time of the station S1 indicated by the timetable database DB3. Further, the prediction unit 12 can use the departure time of the station S2 shown as the next station of the station S1 in FIG. 3 in the calculation process of the predicted arrival time at each handover point PB1, PD1, PG1. Further, when calculating the predicted arrival time at each handover point PB1, PD1, PG1, the prediction unit 12 determines the distance on the route R1 between the stations S1, S2, and the handover points PB1, PD1, PG1, and the station S1. The ratio of the distance on the path R1 can be used. Further, the prediction unit 12 corrects the predicted arrival time at each handover point PB1, PD1, PG1 by using the information indicating the position of the moving body V1 collected by the collection unit 11 and the information indicating the time when the information is collected. It is desirable to do. Thereby, the prediction unit 12 can correct the deviation between the operation schedule and the actual operation state of the moving body V1, and can obtain a more accurate predicted arrival time. Furthermore, when the timetable database DB3 includes information on the stop time at each station and the fluctuation of the traveling speed in the section between the stations, the arrival at each handover point with higher accuracy using these information The predicted time can be predicted. The predicted arrival time calculated for each handover point in this way is a predicted handover time at which each mobile terminal UE in the mobile body V1 is predicted to be handed over to each base station BS.

  Based on the results obtained as described above, the prediction unit 12 provides a handover sequence indicating the order of the base stations BS through which each mobile terminal UE that moves in accordance with the operation of the mobile unit V1 passes to these base stations BS. A handover schedule indicating the predicted handover time is created.

  FIG. 6 shows an example of a handover schedule. Among the elements shown in FIG. 6, the same elements as those shown in FIGS. 1 to 5 are denoted by the same reference numerals, and the description thereof is omitted.

  The handover schedule includes information indicating an operation section in which the mobile terminal may stay in the moving body and information indicating a handover sequence corresponding to the mobile terminal ID for identifying the mobile terminal. The handover schedule includes information indicating a handover point corresponding to each handover sequence and a predicted handover time.

  In addition, the operation section in which each mobile terminal may stay in the mobile body includes the position information when the identification information of the mobile terminal is first notified from the terminal device 1 mounted on the mobile body V, and the mobile body. You may set based on the information which shows the operation route of V. For example, the prediction unit 12 illustrated in FIG. 1 moves the user of the mobile terminal based on the position information when the identification information of the mobile terminal is first notified from the terminal device 1 mounted on the mobile object V. You may identify the station which boarded the body V as a boarding station. And you may specify the station shown as the end point of the operation route of the said mobile body as an alighting station where the said portable terminal alights from the mobile body V. FIG. Note that, as will be described later, when information indicating the section of the user of each mobile terminal on the moving body V is acquired, the operation in which each mobile terminal may stay in the mobile body based on this information. The section can be specified with higher accuracy.

  For example, the handover schedule illustrated in FIG. 6 includes the boarding station “S0” and the getting-off station as information indicating an operation section in which the mobile terminal UE indicated by the mobile terminal ID “UE-1” may stay in the moving body. “S3” is included. The handover schedule includes information indicating that the mobile terminal UE is handed over to the base stations BS-B, BS-D, and BS-G in order as part of the handover sequence. In FIG. 6, the symbol BS-i indicates the base station BS where the mobile terminal UE stays in front of the base station BS-B.

  The handover schedule includes a handover point “PB1” and a predicted handover time “tb1” corresponding to the handover sequence “BS-i → BS-B”. Similarly, this handover schedule includes a handover point “PD1” and a predicted handover time “td1” corresponding to the handover sequence “BS-B → BS-D”. The handover schedule includes a handover point “PG1” and a predicted handover time “tg1” corresponding to the handover sequence “BS-D → BS-G”. Further, this handover schedule includes information indicating respective handover points and predicted handover times corresponding to the handover sequences before and after a part of the above-described handover sequence.

  Furthermore, the prediction unit 12 performs a similar process using the information collected by the collection unit 11 corresponding to each mobile terminal UE in the mobile body V1, thereby obtaining a handover schedule corresponding to each mobile terminal UE. Can be created. In addition, the prediction unit 12 creates a similar handover schedule for the mobile terminal in the mobile body based on the information collected by the collection unit 11 from the terminal device mounted on another mobile body that is operated according to another operation route. It can also be created. In the following description, when the mobile bodies that move according to the operation route are collectively referred to as the mobile body V.

  As described above, based on the handover schedule created by the prediction unit 12 for the mobile terminal UE, the reservation unit 13 illustrated in FIG. 1 reserves resources used by the mobile terminal UE as follows. .

  For example, the reservation unit 13 executes a process of reserving a channel to be allocated to each mobile station UE to each base station BS prior to a predicted handover time corresponding to a handover to each base station BS included in the handover schedule of the mobile terminal UE. May be. For example, the reservation unit 13 reserves a channel to be allocated to the mobile terminal UE to each base station BS via the network control device 2 at a time preceding the predicted handover time td1 illustrated in FIG. Also good. At this time, for example, the reservation unit 13 passes the base station ID indicating the handover source base station BS and the mobile terminal ID indicating the mobile terminal UE to the base station BS that is the target of the resource reservation. The allocation-destination mobile terminal UE can be specified. In addition, the reservation unit 13 passes the information indicating the resource allocation destination and the information indicating the predicted handover time to the base station BS that is the target of the resource reservation, so that the resource reservation in the base station BS can be accurately performed. You may specify a specific time.

  As described above, since the predicted handover time to each base station indicated by the handover schedule predicted by the prediction unit 12 reflects the actual operation status of the mobile object V1, the actual handover is performed with very high accuracy. Indicates the time when is performed. That is, for example, the time when the channel reserved by the reservation unit 13 for each base station BS according to the handover schedule illustrated in FIG. 6 is actually allocated to the mobile terminal UE, and the predicted handover time obtained in response to this handover The difference is very small.

  Accordingly, the reservation unit 13 illustrated in FIG. 1 can shorten the time τ that causes each base station BS to reserve the channel to be allocated to the mobile terminal UE before the predicted handover time. That is, the time when the reservation unit 13 reserves a channel to be assigned to the mobile terminal UE in the mobile body V1 with respect to each base station is highly accurate at the time when the mobile terminal UE enters the cell corresponding to each base station. Can be matched.

  Thus, by managing the time for reserving the channel for the mobile terminal UE in the mobile body V1 with respect to each base station, the mobile terminal UE moves through the process of moving together with the mobile body V1. It is possible to guarantee QoS to the user. The resources reserved for the mobile terminal UE in this way are assigned to the mobile terminal UE when the mobile terminal UE enters a cell corresponding to each base station BS- along with the operation of the mobile unit V1. That is, the resource reserved by the resource management device 10 of the present disclosure is hardly wasted without being allocated to the mobile terminal UE.

  As described above, according to the resource management device 10 of the present disclosure, it is possible to reserve resources that are not excessive or insufficient to guarantee QoS for the mobile terminal UE that moves together with the mobile body V1. Therefore, by applying the resource management device 10 disclosed in the present disclosure to a wireless communication system using a wide area wireless communication network, it is possible to provide high-quality services to a large number of mobile terminals by effectively using limited resources. It becomes. As described above, according to the resource reservation apparatus 10 disclosed in the present disclosure, a company that provides a wireless communication service using a wide-area wireless communication network can make the most of existing facilities, and thus maintains a mobile communication system. The cost required to do so can be reduced.

  Moreover, according to the resource management device 10 of the present disclosure, there is no need to acquire information indicating the movement route used for predicting the handover schedule or position information from the user's mobile terminal UE. For this reason, the user's mobile terminal can be identified with high accuracy while maintaining the user's privacy, and the resources allocated to the mobile terminal can be used for notification of location information, etc. Don't spend on. That is, according to the resource management device 10 of the present disclosure, it is possible to reserve a resource allocated to each mobile terminal so that each user can enjoy a desired QoS without burdening each individual user. Can do.

  Furthermore, by utilizing the handover schedule generated in the process of realizing resource reservation by the resource management device 10 of the present disclosure, it is possible to more reliably provide resources to individual mobile terminals in an environment in which a plurality of moving objects are operated. Reservation can be realized.

  FIG. 7 shows another embodiment of the resource management device 10. 7 that are the same as those shown in FIG. 1 are given the same reference numerals, and descriptions thereof are omitted.

  The prediction unit 12 illustrated in FIG. 7 includes a handover sequence creation unit 121, a handover sequence database (DB) 122, a search unit 123, and a handover time prediction unit 124.

  Based on the base station database DB1 and the route database DB2, the handover sequence creation unit 121 creates in advance a handover sequence indicating the order of handover performed by each base station for mobile terminals in a moving body that moves along various routes. . Then, the handover sequence creation unit 121 stores the handover sequence created for each route in the handover sequence database 122 corresponding to each route.

  FIG. 8 shows an example of the handover sequence database 122 illustrated in FIG. Among the elements shown in FIG. 8, the same elements as those shown in FIGS. 1 to 6 are denoted by the same reference numerals, and the description thereof is omitted.

  The handover sequence database 122 holds a handover sequence for each section delimited by each station included in the route corresponding to each route indicated by a combination of the route ID and information indicating the end point or direction.

  Further, as illustrated in FIG. 8, the handover sequence database 122 preferably includes information indicating a handover point corresponding to each handover included in the handover sequence.

  Note that the handover sequence illustrated in FIG. 8 corresponds to a section between the station S1 and the station S2 on the operation route indicated by the combination of the route ID “R1” and the end point / direction “up” in the handover sequence database 122. As part of the handover sequence that is stored. Similarly, the handover sequence database 122 includes a handover sequence corresponding to each section including a section between the stations S0 and S1 and a section between the stations S2 and S3 on the operation route. Further, the handover sequence database 122 is a handover sequence corresponding to each section included in an operation route indicated by a combination of the route ID “R1” and the end point / direction “downward” or an operation route indicated by another route ID. May be included.

  The handover sequence database 122 does not change as long as the operation route and the arrangement of the base stations BS are fixed. Therefore, the handover sequence generation unit 121 can generate a resource prior to starting the resource reservation process.

  Next, a method for specifying a handover sequence corresponding to each mobile terminal in the moving body based on the handover sequence database 122 obtained in this way will be described.

  Here, the collection unit 11 illustrated in FIG. 7 moves the mobile terminal ID indicating the mobile terminal UE of the user who has newly boarded the moving body V equipped with the terminal device 1 from the terminal device 1. It may be collected together with the identification information of the body V. In this case, the time when the collection unit 11 collects the mobile terminal ID of each mobile terminal UE indicates the time when the user of the mobile terminal UE gets on the moving body V.

  First, the search unit 123 searches the timetable database DB3 for information indicating the operation route of the mobile body based on the mobile body ID included in the information collected from the terminal device 1 by the collection unit 11. By this search processing, the search unit 123, for example, based on the identification information indicating the mobile object V1 illustrated in FIG. 1, the route ID “indicating the operation route of the mobile object V1 from the timetable database DB3 illustrated in FIG. A combination of “R1” and the end point / direction “up” can be acquired. At this time, the search unit 123 compares the time when the collection unit 11 collects the identification information of each mobile terminal UE with the departure time of each station included in the operation route of the moving object V in the timetable database DB3. You may specify the boarding station in which the user of the portable terminal UE boarded the mobile body V.

  Next, the search unit 123 searches the handover sequence database 122 for a handover sequence after the boarding station specified as described above, among the handover sequences corresponding to the acquired information indicating the operation route. In this manner, a handover sequence corresponding to a section in which this mobile terminal may stay in the moving object V can be acquired from the handover sequence database 122 corresponding to each mobile terminal.

  The handover time prediction unit 124 illustrated in FIG. 7 calculates the predicted handover time for each handover included in the handover sequence obtained by the search process by the search unit 123 as described with reference to FIGS. To do. At this time, the handover time predicting unit 124 specifies the position of the moving object V on the operation route based on the information indicating the position of the moving object V included in the information obtained by the collecting unit 11 and the route database DB2. May be. Then, the specified position on the operation route may be used for calculation processing of a predicted handover time corresponding to each handover. In addition, the handover time prediction unit 124 creates a handover schedule including the calculated predicted handover time, and passes this handover schedule to the reservation unit 13 via the handover schedule holding unit 125.

  In this manner, the prediction unit 12 illustrated in FIG. 7 is configured for each base station that passes in the process of moving the user along with the operation of the moving body when the user gets on the moving body. The handover schedule can be predicted.

  Next, reservation of resources to be allocated to the mobile terminal UE in the mobile body is realized with higher accuracy on the basis of the handover schedule predicted for the mobile terminal UE of each user riding on the mobile body V in this way. The method will be described.

  The reservation unit 13 illustrated in FIG. 7 includes an estimation unit 131 and a control unit 133. Based on the handover schedule predicted as described above, the estimation unit 131 illustrated in FIG. 7 estimates a change in the remaining amount of resources that can be allocated in each base station BS accompanying the operation of the mobile unit V. Further, the control unit 133 illustrated in FIG. 7 reserves resources for each base station BS based on the handover schedule held in the handover schedule holding unit 125 and the estimation result obtained by the estimation unit 131. To control. When the estimation result indicates that there is a possibility that the resource reservation destination base station BS will be short of resource supply, the control unit 133 prior to the resource reservation, the mobile terminal UE connected to the base station BS Control to hand over a part to another base station BS is performed. Note that, as illustrated in FIG. 7, the control unit 133 may realize resource reservation by requesting the network control device 2 to perform resource reservation processing for each base station BS.

  Here, the processing of the estimation unit 131 illustrated in FIG. 7 will be described. The estimation unit 131 uses, for example, the free time at the time when the mobile unit V enters the cell using the total number Rdv of the channels allocated to the mobile terminals UE in the mobile unit V passing through the cell corresponding to each base station BS. The number of channels may be predicted. A free channel is a channel that has not been allocated in each base station BS. That is, the number of free channels is an example of a quantity indicating the remaining amount of resources in each base station BS. In the following description, the number of free channels predicted by the estimation unit 131 is referred to as a predicted free channel number.

  For example, the estimation unit 131 may obtain the above-mentioned total sum Rdv of the number of channels in the handover schedule holding unit 125 by counting the mobile terminal IDs set with the same predicted handover time for the handover to each base station BS. Good. Then, the estimation unit 131 may obtain the predicted number of free channels by subtracting the total number Rdv of the number of channels from the average number of free channels Rf of each base station BS. Note that the estimation unit 131 can calculate the average number of free channels Rf in advance based on, for example, statistical data indicating the resource usage status in each base station BS. Then, the estimation unit 131 may use the calculated average free channel number Rf for calculating the predicted free channel number.

  Next, when two operation routes R1 and R2 pass through a cell corresponding to one base station BS, the base station accompanying the movement of the mobile bodies V1 and V2 operated according to these operation routes R1 and R2 A method for obtaining the number of predicted free channels in the BS will be described.

  By the way, in an urban area, there are areas where a plurality of railway lines and bus lines are concentrated, and in such an area, two operation routes R1 and R2 correspond to one base station BS. There is a part that passes through the cell. In such a place, since the mobile terminals UE in the plurality of mobile bodies V1, V2 operated along these operation routes R1, R2 stay in the cell at the same time, the resources of the corresponding base station BS are insufficient. there is a possibility.

  Next, when there are a plurality of mobile bodies V1 and V2 that operate according to a plurality of adjacent operation routes R1 and R2, the estimation unit 131 illustrated in FIG. A process for estimating the fluctuation will be described.

  FIG. 9 is a diagram for explaining the arrangement of a plurality of routes R1, R2 and the base station BS. Note that among the elements shown in FIG. 9, elements equivalent to those shown in FIG. 5 are denoted by the same reference numerals and description thereof is omitted.

  In FIG. 9, code | symbol S4 shows one of the stations provided in operation route R2. In FIG. 9, symbols PA2, PD2, and PF2 indicate handover points at which the mobile terminal UE in the mobile unit V2 is handed over to the base stations BS-A, BS-D, and BS-F, respectively.

  In the example of FIG. 9, the operation route R1 and the operation route R2 are both arranged so as to pass through the inside of the cell D corresponding to the base station BS-D. In such a case, the estimation unit 131 illustrated in FIG. 7 determines the number of predicted free channels in consideration of whether or not there is an overlap in the period during which the plurality of moving bodies V pass through the cell corresponding to the base station BS. It is desirable to estimate.

  FIGS. 10A and 10B show examples of temporal changes in the number of predicted free channels in the base station BS. Note that among the elements shown in FIG. 10, elements equivalent to those shown in FIG. 6 are denoted by the same reference numerals and description thereof is omitted.

  10A and 10B, the horizontal axis indicates time t, and the vertical axis indicates the predicted free channel number Fe. 10A and 10B, the symbol Rfd indicates the average number of free channels calculated in advance corresponding to the base station BS-D. 10A and 10B, symbol td2 indicates the predicted handover time to the base station BS-D predicted for the mobile terminal UE in the mobile object V2. 10A and 10B, the symbol tf2 indicates the time at which the mobile terminal UE in the mobile unit V2 is handed over from the base station BS-D to the adjacent base station BS-F.

  Also, in FIGS. 10A and 10B, symbol Rdv1 indicates the total number of channels allocated to the mobile terminal UE in the mobile unit V1, and symbol Rdv2 indicates a channel allocated to the mobile terminal UE in the mobile unit V2. Indicates the total number of 10A and 10B, the period during which the mobile body V1 passes through the cell D is the period from time td1 to time tg1. 10A and 10B, the period during which the mobile body V2 passes through the cell D is the period from time td2 to time tf2.

  The graph Ga illustrated in FIG. 10A is estimated by the estimation unit 131 when the moving object V2 illustrated in FIG. 9 passes through the cell D illustrated in FIG. It shows the change in the predicted number of free channels Fe. This graph Ga is an example of a change in the predicted number of free channels Fe when there is no overlap in the period in which the two mobile bodies V1 and V2 pass through the cell D.

  As can be seen from this graph Ga, the predicted free channel number Fe of the base station BS-D is calculated from the average free channel number Rfd in the period in which the mobile units V1 and V2 pass through the mobile terminals UE in the mobile units V1 and V2. The total channel number Rdv1 and Rdv2 decreases.

Therefore, when there is no overlap in the period in which the plurality of mobile bodies V pass through the cell corresponding to the base station BS, the estimation unit 131 calculates the number of predicted free channels Fe for each period in which each mobile body V passes through the cell. You may ask for. In this case, the estimation unit 131 uses the average free channel number Rf corresponding to the base station BS and the total channel number Rdv for the mobile terminal UE in the mobile unit V for the calculation process of the predicted free channel number Fe. The following formula (1) representing the predicted free channel number Fe may be used.
Fe = Rf−Rdv (1)
On the other hand, the graph Gb shown in FIG. 10B shows the predicted number of free channels when the mobile body V1 enters the cell D while the mobile body V2 illustrated in FIG. The change of Fe is shown. This graph Gb is an example of a change in the predicted free channel number Fe estimated by the estimation unit 131 when there are overlaps in the period in which the two mobile bodies V1 and V2 pass through the cell D, respectively. In the example of FIG. 10B, a period from time td1 to time tf2 is a period in which the two mobile bodies V1 and V2 are both staying in the cell D. In this period, the predicted free channel number Fe is a value obtained by subtracting the sum of the total channel numbers Rdv1 and Rdv2 for the mobile terminals UE in the mobile bodies V1 and V2 from the average free channel number Rfd of the base station BS-D. It has become.

Thus, the predicted number of free channels Fe during a period in which a plurality of mobile units V stay in the cell is the average number of free channels Rf in the base station BS corresponding to the cell and the mobile terminal UE in each mobile unit V The channel total number Rdv1 to Rdvn for the destination is expressed as shown in Equation (2).
Fe = Rf− (Rdv1 +... + Rdvn) (2)
When the estimation unit 131 illustrated in FIG. 7 estimates the predicted free channel number Fe using the above-described equation (2) for each base station BS, first, the estimation unit 131 sets the base station BS for each of the plurality of mobile objects V. Sort the corresponding predicted handover times. Based on the sorting result, the estimation unit 131 determines how the periods during which each mobile unit V passes through the cell corresponding to the base station BS overlap. And the estimation part 131 is the channel total number Rdv1 which should be allocated to the portable terminal UE in n mobile body V which stays in the cell corresponding to the said base station BS in the said period for every period from which the manner of duplication differs. The predicted free channel number Fe may be calculated using Rdvn.

  By referring to the temporal change in the predicted number of free channels Fe estimated for each base station BS in this way, the control unit 133, when reserving the allocation of resources, has a shortage of resource supply in the base station BS. Whether or not there is a possibility of occurrence can be determined. For example, the control unit 133 supplies resources in the base station BS when the estimated free channel number Fe estimated by the estimation unit 131 corresponding to the time at which resource allocation is to be reserved is below a predetermined threshold Th. It may be determined that a shortage is predicted. Note that the control unit 133 may set a value indicating the number of channels corresponding to a percentage of the total number of channels held by each base station BS, for example, as the predetermined threshold Th described above.

  For example, according to the graph Gb illustrated in FIG. 10B, at the time td1 at which the handover to the base station BS-D is predicted for the mobile terminal UE in the mobile body V1, the predicted free channel number Fe has the threshold value Th described above. Shown below. Prior to this handover, the control unit 133 refers to the predicted number of free channels Fe estimated corresponding to the above-described time td1 when reserving resources to be allocated to the mobile terminal UE in the mobile body V1. Then, by comparing the predicted number of free channels Fe and the threshold value Th, the control unit 133 can recognize the possibility that the base station BS-D will be short of resource supply at time td1.

  In this way, the control unit 133 illustrated in FIG. 7 recognizes the possibility that the reservation-destination base station BS lacks resource supply before executing resource reservation for the mobile terminal UE in the moving object V. To do. Then, when recognizing the shortage of resource supply, the control unit 133 performs control to hand over a part of the mobile terminal already connected to the resource reservation destination base station BS to one of the adjacent base stations. .

  For example, the control unit 133 transmits the number of connected mobile terminals corresponding to the difference between the predicted free channel number Fe obtained as described above and the threshold value Th from the reservation-destination base station BS to the base station. You may control to hand over to another base station BS adjacent to BS. For example, the control unit 133 can acquire information for specifying the base station BS adjacent to the reservation-destination base station BS by referring to the base station database DB1.

  Since such control can be performed prior to resource reservation, the control unit 133 can secure the resources allocated to the mobile terminal UE in the mobile unit V in the reservation destination base station BS. Therefore, by performing resource reservation after the above-described processing, the control unit 133 can execute the resource allocated to the mobile terminal UE in the moving object V with high accuracy for the base station BS.

  As described above, a control method for enabling resource reservation to be executed with high accuracy based on the handover schedule predicted by the prediction unit 12 illustrated in FIG. 1 or FIG. 7 is, for example, resource management as illustrated in FIG. It can also be realized by the apparatus 10.

  FIG. 11 shows another embodiment of the resource management device 10. 11 that are the same as those shown in FIG. 1 or FIG. 7 are denoted by the same reference numerals and description thereof is omitted.

  The estimation unit 131 illustrated in FIG. 11 includes an update unit 134 and a resource reservation database 135. The update unit 134 illustrated in FIG. 11 updates the resource prediction database 135 as described below based on the handover schedule corresponding to each mobile terminal UE held in the handover schedule holding unit 125. The resource prediction database 135 holds, for example, the number of predicted free channels at each predicted handover time corresponding to a handover with the base station as a handover destination or a handover source, corresponding to the base station ID indicating each base station BS.

  FIG. 12 illustrates an example of the resource prediction database 135 illustrated in FIG. Note that among the elements shown in FIG. 12, elements equivalent to those shown in FIG. 10 are denoted by the same reference numerals and description thereof is omitted.

  The resource prediction database 135 includes information indicating the total number of channels of the base station BS corresponding to each base station BS. For example, the resource prediction database 135 includes the total number of channels Rbmax of the base station BS-B corresponding to the base station ID “BS-B” indicating the base station BS-B. Similarly, the resource prediction database 135 includes the total number of channels Rdmax of the base station BS-D corresponding to the base station ID “BS-D” indicating the base station BS-D.

  Further, the resource prediction database 135 includes information indicating a predicted handover time corresponding to a handover sequence related to the base station BS included in one of the handover schedules as information corresponding to each base station BS.

  For example, the resource prediction database 135 includes time tb1 and time td1 as the predicted handover time corresponding to the handover sequence related to the base station BS-B. Note that the above-described time tb1 is a predicted handover time corresponding to a handover sequence in which the base station BS-B included in the handover schedule obtained for the mobile terminal UE in the mobile V1 illustrated in FIG. 9 is the handover destination. . Similarly, time td1 is a predicted handover time corresponding to a handover sequence in which the base station BS-B included in the handover schedule obtained for the mobile terminal UE in the mobile V1 illustrated in FIG.

  Similarly, the resource prediction database 135 illustrated in FIG. 12 includes time td1 and time tg1 as predicted handover times corresponding to the handover sequence related to the base station BS-D. Note that the above-described time td1 is a predicted handover time corresponding to a handover sequence in which the base station BS-D included in the handover schedule obtained for the mobile terminal UE in the mobile V1 illustrated in FIG. 9 is the handover destination. . The time tg1 is a predicted handover time corresponding to a handover sequence in which the base station BS-D included in the handover schedule obtained for the mobile terminal UE in the mobile V1 illustrated in FIG. 9 is a handover source.

  Further, the resource prediction database 135 includes, as information corresponding to each base station BS, information indicating the number of predicted free channels obtained by the update unit 134 as described later for each predicted handover time related to the base station BS. It is out.

  For example, the updating unit 134 illustrated in FIG. 11 sequentially refers to the handover schedule corresponding to each mobile terminal UE held in the handover schedule holding unit 125. Then, based on each handover sequence included in the referenced handover schedule, the update unit 134 updates the predicted number of free channels of the base station BS related to the handover sequence included in the resource prediction database 135. For example, the updating unit 134 may subtract “1” from the predicted number of free channels at the predicted handover time corresponding to the handover sequence as an update process for the base station BS indicated as the handover destination by the handover sequence.

  Note that the update unit 134 may set an initial value of the number of predicted free channels of each base station BS before starting the update process based on the handover schedule. For example, the updating unit 134 may set the above-described average free channel number Rf in the resource prediction database 135 as an initial value of the predicted free channel number of the base station BS.

  In the resource prediction database 135 illustrated in FIG. 12, the average free channel number Rfb calculated in advance as described above for the base station BS-B corresponding to the base station BS-B is the predicted free channel. It is set as the initial value of the number. Similarly, in this resource prediction database 135, the average free channel number Rfd calculated in advance as described above for the base station BS-D in correspondence with the base station BS-D is the predicted free channel number. Is set as the initial value.

  In this case, the updating unit 134 performs the above-described processing based on the handover schedule corresponding to each mobile terminal UE in the mobile body V1 illustrated in FIG. 9, thereby corresponding to the base station BS-B in FIG. 12. The number of predicted free channels “Rfb−Rdv1” shown in FIG.

  Further, as illustrated in FIG. 9, the updating unit 134 uses the method described with reference to FIG. 10 for a base station corresponding to a cell to which a plurality of mobile bodies V1 and V2 are predicted to pass simultaneously. The number of predicted free channels at each time may be updated.

  For example, the update unit 134 performs the update process described above based on the handover schedule of all the mobile terminals UE in the mobile bodies V1 and V2 illustrated in FIG. 9, so that each predicted handover time is as illustrated in FIG. The prediction free channel corresponding to can be obtained. That is, the update unit 134 predicts the predicted handover time td2 to the base station BS-D corresponding to the mobile terminal UE in the mobile unit V2 as shown in FIG. 12 corresponding to the base station BS-D. The number of channels “Rfd−Rdv2” can be obtained. Similarly, the updating unit 134 can obtain the predicted number of free channels “Rfd− (Rdv2 + Rdv1)” for the predicted handover time td1 to the base station BS-D corresponding to the mobile terminal UE in the mobile unit V1. Further, the updating unit 134 can obtain the predicted number of free channels “Rfd−Rdv1” for the predicted handover time tf2 from the base station BS-D to the base station BS-F corresponding to the mobile terminal UE in the mobile unit V2. it can. Then, the updating unit 134 can obtain the predicted number of free channels “Rfd” for the predicted handover time tg1 from the base station BS-D to the base station BS-G corresponding to the mobile terminal UE in the mobile body V1.

  As described above, according to the updating unit 134 illustrated in FIG. 11, resources in each base station BS are updated by sequentially updating the information in the resource prediction database 135 based on the handover schedule corresponding to each mobile terminal UE. Predict changes in remaining time over time. The processing by the updating unit 134 can be realized by simple processing such as operating the number of predicted free channels corresponding to each base station BS in the resource prediction database 135. Therefore, according to the estimation unit 131 including the update unit 134 and the resource prediction database 135, it is possible to speed up the process of estimating the temporal change in the remaining amount of resources in each base station BS.

  Also, the control unit 133 illustrated in FIG. 11 performs such resource transfer when the mobile terminal connected to the reservation-destination base station BS is handed over to another adjacent base station BS. May be reflected. When the control unit 133 executes such a process, the resource transfer process result by the control unit 133 is reflected in the process of estimating the number of predicted free channels in each base station BS performed by the estimation unit 131 thereafter. Can do.

  Next, a resource management system including the resource management device 10 disclosed herein and the terminal device 1 will be described.

  FIG. 13 shows an embodiment of a resource management system. Note that among the constituent elements shown in FIG. 13, those equivalent to the constituent elements shown in FIG. 1 or FIG. 7 are denoted by the same reference numerals and description thereof is omitted.

  The prediction unit 12 of the resource management apparatus 10 illustrated in FIG. 13 includes a handover sequence database 122 in which a handover sequence generated in advance by the sequence generation unit 121 illustrated in FIG. 7 is registered. The prediction unit 12 includes a boarding section information generation unit 126.

  Further, the collection unit 11 illustrated in FIG. 13 identifies the electronic boarding card used in the electronic payment function installed in the mobile terminal UE, which is acquired by the terminal device 1 together with the mobile terminal ID of each mobile terminal UE. Information may be collected. In addition, the method of acquiring electronic boarding card ID which identifies an electronic boarding card from the portable terminal UE by the terminal device 1 is mentioned later. Further, the collection unit 11 uses, as the mobile terminal ID of the mobile terminal UE, subscriber information recorded in a SIM (Subscriber Identity Module) card mounted on the mobile terminal UE or a SIM card ID for identifying this SIM card. May be collected.

  The boarding section information generation unit 126 illustrated in FIG. 13 is based on the electronic boarding card ID collected by the collection unit 11 corresponding to the mobile terminal UE and the user information database DB4. Riding section information indicating a range of movement along the operation route of the moving body V is generated.

  FIG. 14 shows an example of the user information database DB4. Of the elements shown in FIG. 14, elements equivalent to those shown in FIG. 3 are denoted by the same reference numerals and description thereof is omitted.

  The user information database DB4 illustrated in FIG. 14 corresponds to the electronic boarding card ID “C1”, and information indicating the boarding section in the operation route indicated by the route ID “R1” and the route ID “R2”. And information indicating a boarding section in the operation route. This user information database DB4 is a route ID indicating the operating route of the transfer destination together with information indicating the boarding station S0 and the getting-off station S2 as information indicating the boarding section in the operating route R1 corresponding to the electronic boarding card ID “C1”. “R2” is included. Further, the user information database DB4 includes information indicating the boarding station S2 and the getting-off station Sx as information indicating the boarding section on the operation route R2 corresponding to the electronic boarding card ID “C1”. Note that the information stored in such a user information database DB4 can be provided from, for example, a public transportation that manages the operation of the moving object V.

  The boarding section information generation unit 126 illustrated in FIG. 13 searches the user information database DB4 described above, thereby performing each operation together with the route ID registered corresponding to the electronic boarding card ID received from the collection unit 11. Information indicating the boarding station and alighting station on the route is acquired. By combining the information acquired in this way and the identification information of the mobile terminal UE received from the collection unit 11, the boarding section information generation unit 126 allows each mobile terminal UE to follow the operation route of the moving object V. Riding section information indicating a riding section that is likely to move can be generated.

  The search unit 123 illustrated in FIG. 13 performs a search process on the handover sequence database 122 based on the boarding section information generated for each mobile terminal UE as described above. By this search process, the search unit 123 can acquire a handover sequence corresponding to a range in which each mobile terminal UE moves along the operation route of the moving object V.

  Therefore, based on this handover sequence, the handover time prediction unit 124 can generate a handover schedule that reflects the movement of the user of each mobile terminal UE on the moving body V with high accuracy.

  That is, according to the resource management device 10 illustrated in FIG. 13, when the user of the mobile terminal UE gets on the moving body V, the user gets off the moving body V by using the electronic boarding card ID. The handover schedule up to can be predicted.

  Here, the electronic boarding card ID used for the electronic payment function is not information that directly indicates the movement route of the user of the mobile terminal UE. For this reason, there is little resistance which a user has with respect to providing electronic boarding card ID to the resource management apparatus 10 via the terminal device 1 compared with the case where the information which shows a movement route is provided. Therefore, compared with the possibility that the user cooperates in providing information on the user's own travel route from the user, the user of the mobile terminal UE provides the electronic boarding card ID as described above. The possibility of receiving cooperation is high.

  Therefore, as illustrated in FIG. 13, according to the resource management device 10 having a mechanism for using the electronic boarding card ID, it is possible to further improve the prediction accuracy of the handover schedule without increasing the burden on the user.

  Next, a method in which the terminal device 1 collects the above-described SIM card ID and electronic boarding ID from the mobile terminal UE will be described.

  The terminal device 1 illustrated in FIG. 13 includes a reception unit 3, a transmission unit 4, and a GPS (Global Positioning System) signal processing unit 5. As illustrated in FIG. 13, the reception unit 3 of the terminal device 1 may include a proximity communication interface (I / F: InterFace) 6 such as RFID (radio frequency IDentification) and an information request unit 7. The mobile terminal UE illustrated in FIG. 13 includes a near field communication interface (I / F) 8 such as an RFID and a user information holding unit 9.

  The information request unit 7 of the terminal device 1 illustrated in FIG. 13 transmits a message requesting the transmission of the SIM card ID and the electronic boarding card ID to the nearby mobile terminal UE via the proximity communication interface 6.

  The proximity communication interface 8 of the mobile terminal UE that has received this message acquires the SIM card ID and the electronic boarding card ID from the user information holding unit 9. Then, the near field communication interface 8 transmits the acquired SIM card ID and electronic boarding card ID to the requesting near field communication interface 6.

  Thus, the SIM card ID and the electronic boarding card ID can be acquired from the mobile terminal UE by the receiving unit 3 including the near field communication interface 6 and the information requesting unit 7.

  In addition, the GPS signal processing unit 5 illustrated in FIG. 13 generates information indicating the position of the moving body V1, for example, every predetermined time based on a signal from a satellite included in the GPS. In addition, the transmission unit 4 illustrated in FIG. 13 includes the information indicating the position of the moving object V1 obtained by the GPS signal processing unit 5, the SIM card ID and the electronic boarding of the mobile terminal UE obtained through the reception unit 3. A message including the card ID is transmitted to the resource management apparatus 10. The transmission unit 4 may accumulate SIM card IDs and electronic boarding card IDs of a plurality of mobile terminals UE obtained sequentially via the reception unit 3. For example, when the mobile body V1 departs from a stop such as a station, the transmitter 4 transmits the SIM card ID and the electronic boarding card ID accumulated for each mobile terminal UE and the position of the mobile body V1 obtained immediately before. A message including information indicating the message may be generated. Moreover, the transmission part 4 may transmit the message produced | generated in this way to the resource management apparatus 10 via the network of a mobile communication system.

  As described above, the resource management apparatus 10 can predict a handover schedule for each mobile terminal UE based on the information transmitted in this way, and can perform resource reservation without waste based on the handover schedule. It is as follows.

  Further, by installing the terminal device 1 illustrated in FIG. 13 in each vehicle of the train, for example, the location information of the vehicle unit included in the train can be notified to the resource management device 10. By using such position information, the resource management apparatus 10 can predict a more precise handover schedule for each mobile terminal UE in the vehicle.

  That is, according to the resource management system of the present disclosure illustrated in FIG. 13, to guarantee QoS for each mobile terminal UE based on information that can be collected by using the existing near field communication interface 8 for the mobile terminal UE. It is possible to realize resource reservation that is not excessive or insufficient.

  The resource management device 10 of the present disclosure described above can be realized using, for example, a computer device such as a server device held by a carrier that provides a wireless communication service, as illustrated in FIG.

  FIG. 15 shows a hardware configuration example of the resource management apparatus 10. 15 that are the same as those shown in FIG. 1 or FIG. 13 are given the same reference numerals, and descriptions thereof are omitted.

  The computer device 20 illustrated in FIG. 15 includes a processor 21, a memory 22, a hard disk device (HDD) 23, a database management unit 24, a dedicated line interface 25, and a wireless communication interface 26. The processor 21, the memory 22, the hard disk device 23, the database management unit 24, the dedicated line interface 25, and the wireless communication interface 26 illustrated in FIG. 15 are connected to each other via a bus. The computer device 20 is connected to the base station database DB1, the route database DB2, the timetable database DB3, and the user information database DB4 via the database management unit 24. The computer device 20 is connected to the network control device 2 via a dedicated line interface 25. The computer device 20 is connected to the wide area wireless communication network NW via the wireless communication interface 26 and can collect information from the terminal device 1 via the wide area wireless communication network NW.

  The memory 22 and the hard disk 23 illustrated in FIG. 15 store an application program for the processor 21 to execute the resource management process described above, together with the operating system of the computer device 20. The application program for executing the resource management process described above can be provided by being recorded on a removable disk such as an optical disk, for example. Then, an application program for executing resource management processing may be stored in the memory 22 and the hard disk device 23 by loading the removable disk into an optical drive device (not shown) and performing read processing. Further, an application program for executing resource management processing can be read into the memory 22 and the hard disk device 23 via a communication device (not shown) connected to a network such as the Internet.

  The processor 21 may perform the functions of the collection unit 11, the prediction unit 12, and the reservation unit 13 illustrated in FIG. 1 by executing application programs stored in the memory 22 and the hard disk 23. That is, the resource management device 10 disclosed herein can be realized by using, for example, the processor 21, the memory 22, and the hard disk device 23 included in the computer device 20 illustrated in FIG.

  Further, the handover sequence database 122 illustrated in FIG. 7 can be stored in the memory 22 or the hard disk device 23 in advance. Further, an area for storing the handover schedule holding unit 125 illustrated in FIG. 7 and the resource prediction database 135 illustrated in FIG. 13 may be provided in the memory 22 or the hard disk device 23 in advance. Then, the processor 21 stores the information generated in the process of executing the application program for resource management processing in these areas, so that the handover schedule holding unit 125 and the resource prediction database 135 are formed. Good.

  The application program for resource management processing includes an application program for causing the processor 21 to execute processing for predicting a handover schedule for each mobile terminal UE based on information collected from the terminal device 1. The application program for resource management processing includes an application program for causing the processor 21 to execute processing for reserving resources of each base station BS based on the predicted handover schedule.

  First, a process for predicting the handover schedule of each mobile terminal UE will be described. For example, each time a message from the terminal device 1 arrives, the processor 21 may execute processing for predicting the handover schedule.

  FIG. 16 shows an example of a flowchart of processing for predicting a handover schedule. Each process of step S300 to step S307 illustrated in FIG. 16 is an example of a process included in an application program for a process of predicting a handover schedule. In addition, each processing of step S300 to step S307 is executed by the processor 21.

  First, the processor 21 receives a message transmitted by the terminal device 1 mounted on the mobile unit V via the wireless communication interface 26 and the wide area wireless communication network NW illustrated in FIG. 15 (step S300). This message includes, for example, a mobile body ID corresponding to the mobile body V, position information indicating the position of the mobile body V at the time of transmission of this message, the mobile terminal ID and the electronic information of each mobile terminal UE in the mobile body V The boarding card ID is included.

  Next, the processor 21 specifies the position of the moving body V on the operation route at the time of transmitting this message based on the moving body ID indicating the moving body V included in the message and the position information (step S301). For example, the processor 21 first refers to the timetable database DB3 via the database management unit 24, thereby acquiring the route ID held corresponding to the above-described mobile body ID. Further, the processor 21 collates the position information of each station and each reference point held in the route database DB2 corresponding to the acquired route ID with the position information included in the above-described message, thereby moving the mobile object V. The position on the route of the trip is specified. In addition, when the terminal device 1 transmits the above-described message at a station or a bus stop, the processor 21 limits the collation target with the position information included in the message to the position information indicating the position of the station or the bus stop. Also good.

  Next, the processor 21 sequentially selects a pair of the mobile terminal ID and the electronic boarding card ID of each mobile terminal UE included in the above-described message as information on the mobile terminal UE to be scheduled (step S302). Note that the above-described message may include a pair of a mobile terminal ID and an electronic boarding card ID corresponding to the mobile terminal UE for which a handover schedule has already been created. In this case, the processor 21 may exclude the pair of the portable terminal ID and the electronic boarding card ID from the following processing targets in the processing of step S302.

  Next, the processor 21 combines the information obtained by referring to the user information database DB4 on the basis of the selected electronic boarding card ID and the mobile terminal ID, so that the boarding section information corresponding to the mobile terminal UE is obtained. Is generated (step S303).

  Next, the processor 21 searches the handover sequence database 122 for a handover sequence corresponding to the mobile terminal UE based on the boarding section information obtained in the process of step S303 (step S304).

  Next, the processor 21 creates a handover schedule by calculating a predicted handover time for each handover included in the handover sequence as described with reference to FIGS. 5 and 6 (step S305). The processor 21 stores the handover schedule created in step S305 in the handover schedule holding unit 125 provided in the memory 22 or the hard disk device 23, and uses this handover schedule in the subsequent processing.

  Based on the handover schedule obtained in this way, the processor 21 performs processing for estimating the remaining amount of resources in each base station BS as described later (step S306).

  Thereafter, the processor 21 determines whether or not there is an unscheduled mobile terminal UE for which the prediction of the handover schedule has not yet been completed (step S307). When there is a pair of the mobile terminal ID and the electronic boarding card ID that has not been selected in the process of step S302 described above, the processor 21 returns to the process of step S302 according to the affirmative determination route of step S307. Then, the processor 21 executes the above-described processing from step S303 to step S306 for the new portable terminal ID and electronic boarding card ID pair selected in the processing in step S302.

  In this way, the processor 21 repeats the processing from step S302 to step S307 for the pair of portable terminal ID and electronic boarding card ID corresponding to each portable terminal UE included in the message received in step S301. And when the process about all the pairs of portable terminal ID and electronic boarding card ID is completed, the processor 21 complete | finishes the process which estimates a handover schedule according to the negative determination route of step S307.

  The processor 21 performing the process of step S300 described above is an example of a technique for realizing the function of the collection unit 11 illustrated in FIG. In addition, the processor 21 executing the processes in steps S301 to S305 described above is an example of a technique for realizing the function of the prediction unit 12 illustrated in FIG. The processor 21 can implement the function of the estimation unit 131 illustrated in FIG. 7 by executing the process of step S306 as described later with the handover schedule as a part of the prediction process.

  Note that the processor 21 may execute the process of estimating the resource remaining amount in step S306 illustrated in FIG. 16 at another timing. For example, the processor 21 estimates the remaining amount of resources of each base station BS after the processing for all portable terminal ID / electronic boarding card ID pairs included in the message received in step S307 is completed. May be executed. Further, the processor 21 may execute a process of estimating the remaining amount of resources of each base station BS asynchronously with the arrival of a message from the terminal device 1.

  Next, a method for realizing the process of estimating the remaining amount of resources of each base station BS by the processor 21 executing the application program will be described.

  FIG. 17 shows an example of a flowchart of processing for estimating the remaining resource amount. Each process of step S311 to step S318 illustrated in FIG. 17 is an example of a process included in the application program for the process of estimating the remaining resource amount, and corresponds to the process of step S306 illustrated in FIG. In addition, each processing of step S311 to step S318 is executed by the processor 21.

  The processor 21 receives the handover schedule generated corresponding to the mobile terminal UE selected in the process of step S302 by the process of step S305 illustrated in FIG. 16 (step S311).

  Next, the processor 21 selects an unprocessed handover included in the received handover schedule as a processing target handover (step S312). For example, it is desirable that the processor 21 selects the handover to be processed in the order of the corresponding predicted handover time from the handover sequence included in the handover schedule.

  Next, the processor 21 refers to the resource prediction database 135 provided in the memory 22 or the hard disk device 23, and acquires the predicted number of free channels of the handover destination base station BS indicated by the selected handover (step S313). .

  Then, the processor 21 determines whether resources are sufficient in the handover destination base station based on the predicted number of free channels acquired in step S313 (step S314). For example, when the acquired number of predicted free channels is equal to or less than the above-described threshold Th, the processor 21 determines that there is a possibility of resource shortage in the handover destination base station (No determination in step S314). On the other hand, when the acquired number of predicted free channels is larger than the above-described threshold Th, the processor 21 determines that resources are sufficient in the handover destination base station (Yes determination in step S314).

  In the negative determination route in step S314 described above, the processor 21 first selects a base station BS to which a shortage of predicted resources is to be transferred from other base stations BS adjacent to the handover destination base station BS. (Step S315). For example, the processor 21 refers to the base station database DB1 via the database management unit 24 illustrated in FIG. 15 to obtain information indicating a plurality of base stations BS arranged adjacent to the handover destination base station BS. Can be acquired. Then, the processor 21 selects one of these base stations BS as a transfer destination base station BS to which a part of the mobile terminal connected to the handover destination base station BS is handed over.

  Next, the processor 21 reflects, in the resource prediction database 135, the change in the predicted number of free channels due to the resource transfer process for the transfer destination base station BS and the handover destination base station BS selected in step S315 (step S316). . For example, the processor 21 sets the predicted number of free channels corresponding to the predicted handover time described above, which is held in the predicted resource database 135 corresponding to the base station BS to be transferred selected in step S315, according to the amount of resource transfer. Decrease. In addition to this processing, the processor 21 determines the number of predicted free channels corresponding to the predicted handover time described above, which is held in the predicted resource database 135 corresponding to the handover destination base station BS, according to the amount of resource transfer. increase. In this way, the processor 21 can reflect the change in the number of predicted free channels due to the resource transfer process in the resource prediction database 135.

  In the affirmative determination route in step S314 described above, the processor 21 skips the processes in steps S315 and S316 described above. The affirmative determination route processing of step S314 and the negative determination route processing of step S314 merge at step S317.

  In step S317, the processor 21 reflects in the resource prediction database 135 the change in the remaining resource of each base station BS that is predicted when the handover selected in step S312 is executed. For example, the processor 21 adds the numerical value “1” to the predicted number of free channels at the predicted handover time corresponding to the base station BS that is the handover source of the mobile terminal UE described above in the handover. On the other hand, the processor 21 subtracts the value “1” from the predicted number of free channels at the predicted handover time corresponding to the base station BS that is the handover destination of the mobile terminal UE described above in the handover. As described above, the processor 21 updates the number of predicted free channels of each base station BS as described with reference to FIGS. 11 and 12. By performing the operation on the number of predicted free channels, resources are released in the handover source base station BS by the above-described handover, and conversely, resources are reserved in the handover destination base station BS. Can do.

  After the process of step S317 described above is completed, the processor 21 determines whether there is an unprocessed handover (step S318). When an unprocessed handover remains in the handover schedule received in the process of step S311, the processor 21 returns to the process of step S312 according to the affirmative determination route of step S318. In step S312, the processor 21 selects a new handover as a processing target from the handover schedule, and executes the above-described steps S313 to S317 for the selected handover.

  In this way, the processor 21 executes the processes for all the handovers included in the handover schedule by repeatedly executing the processes of steps S312 to S318. When the processing for all handovers is completed, the processor 21 ends the process of estimating the remaining resource according to the negative determination route of step S318, and returns to the process of step S307 illustrated in FIG.

  As described above, the function of the update unit 134 illustrated in FIG. 11 can be realized by the processor 21 executing the process of step S317. Further, the processor 21 executes the processes of steps S312 to S316 prior to the process of step S317, thereby realizing a part of the function of the control unit 133 illustrated in FIG. That is, when the processor 21 executes the process described above, a change in the remaining amount of the resource due to the transfer process performed by the control unit 133 to execute the resource reservation can be anticipated and reflected in the resource prediction database 135.

  Next, a technique for realizing the process of reserving resources to be allocated to individual mobile terminals UE in the moving body V by the processor 21 executing an application program will be described.

  FIG. 18 shows an example of a flowchart of resource reservation processing. Each process of step S321 to step S329 illustrated in FIG. 18 is an example of a process included in the application program for the resource reservation process. In addition, each processing of step S321 to step S329 is executed by the processor 21.

  The processor 21 may execute each process of Step S321 to Step S330 illustrated in FIG. 18 based on the handover schedule held in the handover schedule holding unit 125 corresponding to each mobile terminal UE. In this case, the processor 21 performs the process of reserving the resources allocated to each mobile terminal UE for each base station BS indicated by the handover schedule in parallel, whereby the function of the reservation unit 13 illustrated in FIG. Can be realized.

  In step S321 illustrated in FIG. 18, the processor 21 selects a handover sequence for which resource reservation processing has not yet been completed, from the handover sequences included in the handover schedule. In the following description, the handover destination base station BS indicated by the selected handover sequence is referred to as a resource reservation target base station BS.

  Next, the processor 21 refers to the resource prediction database 135 for the resource reservation target base station BS (step S322). With this reference, the processor 21 acquires the predicted free channel number Fe of the resource reservation target base station BS at the predicted handover time corresponding to the handover sequence.

  Next, the processor 21 determines whether or not resource reservation is possible in the resource reservation target base station BS by comparing the predicted free channel number Fe acquired in step S322 with the above-described threshold Th. (Step S323).

  When the predicted number of free channels Fe is equal to or greater than the threshold value Th, the processor 21 determines that resource reservation is possible (positive determination in step S323). In the affirmative determination route in step S323, the processor 21 skips the processes in steps S324, S325, and S326, and proceeds to the process in step S327.

  On the other hand, when the predicted number of free channels Fe is smaller than the threshold Th, the processor 21 determines that there is a possibility that the resource cannot be reserved (No determination in step S323). In the affirmative determination route in step S323, the processor 21 first sets a transfer reservation time for a process for reserving a resource transfer from the handover destination base station BS to another base station BS (step S324). For example, the processor 21 may set the transfer reservation time at a time that precedes the predicted handover time corresponding to the selected handover sequence by a predetermined grace time. Note that the processor 21 can smoothly execute resource transfer by setting, for example, a time of about 1 minute as the above-described grace period.

  After that, the processor 21 waits until the transfer reservation time in step S325, and then requests the network control device 2 to perform resource transfer processing via the dedicated line interface 25 illustrated in FIG. 15 (step S326). In the process of step S326, the processor 21 may confirm the actual number of free channels in the resource reservation target base station BS, for example, via the network control device 2. Then, the processor 21 may request the network control device 2 to perform a resource transfer process only when the base station BS determines that the resource is insufficient based on the actual number of free channels. In this way, when the resource of the base station BS subject to resource reservation is insufficient, the control unit 133 illustrated in FIG. 11 transfers a part of the mobile terminal connected to the base station BS to another base station BS. Control for handover can be realized. At this time, the processor 21 becomes a transfer destination from among the base stations BS adjacent to the resource reservation target base station BS based on the base station database DB1 in the same manner as the process of step S315 illustrated in FIG. A base station BS can be selected. Further, when selecting the transfer destination base station BS, the processor 21 can use information held in the resource prediction database 135 for each base station BS adjacent to the resource reservation target base station BS.

  The affirmative determination route and the negative determination route in step S323 join in the processing in step S327. In step S327, the processor 21 waits until the resource reservation time set based on the predicted handover time corresponding to the handover sequence selected in step S321. The processor 21 considers the time required for the exchange of information between the network control device 2 and the base station BS that is the target of resource reservation, for example, sets a time that precedes the predicted handover time by a predetermined time as a resource. The reservation time may be set.

  When the resource reservation time described above arrives, the processor 21 reserves the channel of the resource reservation target base station BS for the mobile terminal UE corresponding to the handover schedule being processed via the network control device 2. (Step S328). At this time, the processor 21 has, as information indicating the allocation destination of the reserved channel, a mobile terminal ID indicating the allocation-destination mobile terminal UE, and a base station ID indicating the handover source base station BS corresponding to the mobile terminal UE, May be notified to the resource reservation target base station BS. Further, the processor 21 uses, as information indicating the handover destination of the mobile terminal UE, the mobile terminal ID indicating the mobile terminal UE and the base station ID indicating the resource reservation target base station BS as the handover source base station BS described above. May be notified. By notifying these pieces of information to the two base stations BS described above, the mobile terminal UE can be handed over according to the handover sequence with high accuracy.

  In this way, the processor 21 executes the processes of steps S327 and S328, so that the control unit 133 illustrated in FIG. 11 has a function of reserving resources for each base station BS based on the handover schedule. Can be realized.

  Thereafter, the processor 21 determines whether or not there is an unprocessed handover sequence in the handover sequence included in the handover schedule to be processed (step S329). When there is an unprocessed handover sequence, the processor 21 returns to the process of step S321 according to the affirmative determination route of step S329, and starts a process for a new handover sequence.

  When the processing for all the handovers included in the handover schedule is completed, the processor 21 ends the resource reservation processing for this handover schedule according to the negative determination route in step S329.

  For each handover sequence included in the handover schedule, the processor 21 may execute the processes in steps S322 to S328 related to resource reservation associated with the handover sequence in parallel.

  As described with reference to FIGS. 16 to 18, the processor 21 executes an application program for resource management processing, whereby the collection unit 11, the prediction unit 12, and the resource management device 10 disclosed in the present disclosure are included. The function of the reservation unit 13 can be realized.

  That is, the resource management device 10 disclosed herein can be realized by cooperation of hardware included in the computer device illustrated in FIG. 15 and an application program for resource management processing.

  Similarly, the terminal device 1 included in the resource management system of the present disclosure can also be realized using a computer device.

And the computer apparatus 30 can receive the information which these near field communication apparatuses Rc1-RCk each collected from at least 1 portable terminal UE via the general purpose interface 34 mentioned above. In the following description, when the proximity wireless communication devices Rc1 to RCk are generically referred to, they are simply referred to as the proximity wireless communication device RC.

  The memory 32 and the hard disk device 33 illustrated in FIG. 19 store an application program executed by the processor 31 in order to implement the terminal device 1 by the computer device 30 together with the operating system of the computer device 30. The application program includes an application program for realizing information acquisition processing by the terminal device 1, and can be provided by being recorded on a removable disk such as an optical disk. Then, an application program for executing information acquisition processing may be stored in the memory 32 and the hard disk device 33 by loading the removable disk in an optical drive device (not shown) and performing reading processing. In addition, an application program for executing information acquisition processing can be read into the memory 32 and the hard disk device 33 via a communication device (not shown) connected to a network such as the Internet.

  The processor 31 may fulfill the functions of the receiving unit 3 illustrated in FIG. 13 by causing the application program stored in the memory 32 and the hard disk device 33 to cooperate with the general-purpose interface 34 and each close proximity wireless communication device RC. Further, the processor 31 may fulfill the function of the transmission unit 4 illustrated in FIG. 13 by cooperating the application program stored in the memory 32 and the hard disk 33 with the wireless communication interface 35. That is, the terminal device 1 included in the resource management system disclosed herein can be realized using, for example, the computer device 30 and the GPS signal processing unit 5 illustrated in FIG.

  The proximity wireless communication devices RC1 to RCk illustrated in FIG. 19 are arranged as illustrated in FIG. 20, for example, in the moving body V on which the terminal device 1 is mounted.

  FIG. 20 shows an arrangement example of the proximity wireless communication device RC in the moving body. In FIG. 20, reference numerals RC1 to RC5 indicate proximity wireless communication devices RC, and reference numerals UE-1 and UE-2 indicate mobile terminals, respectively.

  Moreover, in FIG. 20, it is an example of arrangement | positioning of suitable near field communication apparatus RC about the case where a moving body is a train vehicle. In this example, the proximity wireless communication devices RC2, RC3, and RC4 are installed on a pillar that supports a net shelf provided in the vehicle, and the proximity wireless communication devices RC1 and RC5 are installed on a wall beside the doorway. Yes.

  According to the proximity wireless communication device RC installed as illustrated in FIG. 20, when the user tries to enter the vehicle or while moving in the vehicle, the RFID between the portable terminal UE of the user and the user A connection through the interface can be established.

  Note that the example of FIG. 20 illustrates a state in which a connection by the RFID interface is established between the mobile terminal UE-1 held by the person on the left side and the proximity wireless communication device RC2. In addition, as with the mobile terminal UE-2 held by the right person, it is possible to realize acquisition of information by the RFID interface when passing near the proximity wireless communication device RC5 installed beside the doorway.

  Next, a method for realizing information acquisition processing by the terminal device 1 by the processor 31 executing an application program will be described.

  FIG. 21 shows an example of a flowchart of information acquisition processing. Each process of step S331 to step S340 illustrated in FIG. 21 is an example of a process included in an application program for the resource reservation process. In addition, each processing of step S331 to step S340 is executed by the processor 31 illustrated in FIG.

  Here, since the mobile terminal V enters and leaves the mobile body V on which the terminal device 1 is mounted only while the mobile body V is stopped at a stop such as a station or a bus stop, the processor 31 moves Each time the body V stops, the following process may be executed.

  The processor 31 waits for establishment of a connection between the close proximity wireless communication device RC and the portable terminal UE by monitoring the state of each close proximity wireless communication device RC via the general-purpose interface 34, for example (step S331).

  The processor 31 determines that the connection with the mobile terminal UE has not been successful when the notification that the synchronization with the mobile terminal UE has been established is received from any of the proximity wireless communication devices RC via the general-purpose interface 34. To do. In this case, the processor 31 returns to the process of step S331 according to the negative determination route of step S332, and repeats the process of waiting for establishment of a connection with the mobile terminal UE.

  On the other hand, when receiving a notification that synchronization with the mobile terminal UE has been established, the processor 31 determines that the connection with the mobile terminal UE has been successful, and proceeds to the process of step S333 according to the affirmative determination route of step S332. .

  In step S333, the processor 31 transmits the mobile terminal ID and the electronic device to the mobile terminal UE connected to the proximity wireless communication device RC via the general-purpose interface 34 and the proximity wireless communication device RC that is the transmission source of the notification.

  FIG. 24 shows an example of a flowchart of RFID communication processing. Each process of step S341 to step S349 illustrated in FIG. 24 is an example of a process included in an application program for RFID communication processing. In addition, each processing of step S341 to step S349 is executed by the processor 41 illustrated in FIG. 22 or FIG.

  First, the processor 41 waits for establishment of a connection between the electronic payment function unit 45 and the proximity wireless communication device RC, for example, by monitoring the state of the RFID interface 48 included in the electronic payment function unit 45 (step S341).

  When the processor 41 does not receive a notification from the electronic settlement function unit 45 that the synchronization with the proximity wireless communication device RC has been established in the process of step S341, the processor 41 has not successfully connected to the proximity wireless communication device RC. Judge that In this case, the processor 41 returns to the process of step S341 according to the negative determination route of step S342, and repeats the process of waiting for establishment of a connection with the close proximity wireless communication device RC.

  On the other hand, when the notification that the synchronization with the close proximity wireless communication device RC is established is received, the processor 31 determines that the connection with the close proximity wireless communication device RC is successful, and the step S343 is performed according to the affirmative determination route of step S342. Proceed to the process.

  In step S343, the processor 41 waits for a request from the close proximity wireless transfer device RC in the same manner as in step S341. Based on the state of the RFID interface 48 included in the electronic payment function unit 45 in the process of step S343, the processor 41 determines whether a request from the close proximity wireless communication device RC has been received (step S344).

  When the state change of the RFID interface 48 included in the electronic settlement function unit 45 does not indicate that the request from the close proximity wireless communication device RC has been received, the processor 41 proceeds to the process of step S343 according to the negative determination route of step S344. Return. In this case, the processor 41 repeats the processes of steps S343 and S344 described above. On the other hand, when the change in the state of the RFID interface 48 included in the electronic payment function unit 45 indicates that the request from the close proximity wireless communication device RC has been received, the processor 41 performs step S345 according to the affirmative determination route of step S344. Proceed to the process.

  In step S345, the processor 41 determines whether the received request is a request from the terminal device 1 based on, for example, a code indicating the content of the received request.

  In the affirmative determination route of step S345, the processor 41 can realize the information acquisition process by executing the processes of steps S346 and S347 illustrated in FIG.

  First, for example, the processor 41 collects the SIM card ID from the SIM card 46 as a portable terminal ID, and collects the electronic boarding card ID from the internal memory 47 in the electronic payment function unit 45 (step S346). Next, the processor 41 transmits the collected pair of portable terminal ID and electronic boarding card ID to the requesting proximity wireless communication device RC via the RFID interface 48 included in the electronic payment function unit 45 (step S347).

  On the other hand, in the negative determination route in step S345 described above, the processor 41 executes processing in response to a request in the same manner as the RFID communication processing before change (step S348).

  The affirmative determination route and the negative determination route in step S345 merge in step S349. In step S349, the processor 41 determines whether or not an instruction to turn off the power of the mobile terminal UE is given via the user interface unit 43, for example.

If power-off has not been instructed yet, the processor 41 returns to the process of step S341 according to the negative determination route of step S349 and waits for a new connection via the RFID interface 48 included in the electronic payment function unit 45. . On the other hand, when an instruction to turn off the power is given, the processor 41 ends the RFID communication process according to the affirmative determination route of step S349.
It is determined whether the request is for a mobile terminal ID and an electronic boarding card ID.

  In this manner, the processor 41 cooperates the electronic payment function unit 45 and the application program for information acquisition processing, so that the existing mobile terminal UE can be adapted to the resource management system disclosed herein.

  Note that the exchange of information between the mobile terminal UE and the terminal device 1 is not limited to the RFID interface, but uses, for example, an interface for close proximity wireless communication such as Bluetooth (registered trademark) or IrDA (Infrared Data Association). May be realized.

  The resource management system including the resource management device 10 of the present disclosure described above can operate in cooperation with an existing wide area wireless communication network. Next, cooperation between the resource management system disclosed herein and the wide area wireless communication network will be described.

  25 and 26 are sequence diagrams illustrating resource management processing by the resource management system disclosed herein. Of the elements shown in FIG. 25 and FIG. 26, elements equivalent to those shown in FIG. 2 or FIG.

  The code | symbol REQ shown in FIG. 25 has shown the information request | requirement using the RFID interface with respect to the portable terminal UE from the terminal device 1. FIG. Reference sign RES indicates a response returned from the mobile terminal UE in response to the information request REQ.

  The terminal device 1 creates a message MES1 including information on each mobile terminal UE acquired in this way, and transmits the created message MES1 to the resource management device 10 via the wide area wireless communication network NW illustrated in FIG. . In response to the reception of this message MES1, the resource management apparatus 10 creates a handover schedule corresponding to each mobile terminal UE by executing a handover schedule prediction process P1. Next, the resource management apparatus 10 executes a process P2 for estimating the remaining resource amount in each base station BS based on the handover schedule created in the handover schedule prediction process P1. Based on the result obtained in the process P2 for estimating the remaining amount of resources and the handover schedule predicted for each mobile terminal UE, the resource management apparatus 10 should allocate to each mobile terminal UE in each base station BS. Execute processing to reserve resources.

  In the following description, based on the handover schedule corresponding to the mobile terminal UE predicted as described above, the resource management device 10 and the wide area wireless communication network when reserving resources for the base station BS-D Will be described.

  For example, the resource management apparatus 10 starts a series of processes executed for reserving resources for the base station BS-D at the time indicated by the reference numeral “td1-dt” in FIG. Note that the above-described time is based on the predicted handover time td1 corresponding to the handover sequence from the base station BS-B to the base station BS-D and the predetermined grace time dt included in the handover schedule corresponding to the mobile terminal UE. It may be set in advance. In FIG. 25, an arrow with a symbol “COM” indicates that the mobile terminal UE is connected to the base station BS-B.

  The resource management apparatus 10 first causes the mobile station UE to hand over the mobile terminal UE to the base station BS-D via the network control apparatus 2 to the base station BS-B indicated as the handover source by the handover sequence described above. To be notified. This notification includes information notification from the resource management apparatus 10 indicated by reference numeral “INF1” in FIG. 25 to the network control apparatus 2, and from the network control apparatus 2 indicated by reference numeral “ODR1” to the base station BS-B. It may be realized by the instruction. In response to this notification, the base station BS-B executes a process P3 for holding the acquired information regarding the handover destination of the mobile terminal UE in the internal memory.

  Further, the resource management apparatus 10 notifies the base station BS-D, which is indicated as the handover destination by the above-described handover sequence, via the network control apparatus 2 that the resource to be allocated to the mobile terminal UE is reserved. . This notification includes information notification from the resource management apparatus 10 indicated by reference numeral “INF2” in FIG. 25 to the network control apparatus 2, and from the network control apparatus 2 indicated by reference numeral “ODR2” to the base station BS-B. It may be realized by the instruction. Further, it is desirable that the resource management apparatus 10 includes the mobile terminal ID and the base station ID indicating the handover source base station BS-B as information for specifying the mobile terminal UE in the notification. In response to this notification, the base station BS-D executes a process P4 for securing a reservation resource to be allocated to the mobile terminal UE based on the acquired information specifying the mobile terminal UE.

  In this way, for the base station BS-d where the mobile terminal UE is predicted to be handed over next while the mobile terminal UE maintains a connection with the base station BS-B, Resources to be allocated to the mobile terminal UE can be reserved.

  Note that when it is estimated that the remaining resource amount in the predicted handover destination base station BS-D is insufficient, the resource management device 10 is currently connected to the base station BS-D via the network control device 2. A part of the mobile terminal may be transferred to another base station BS. Since the estimation result of the resource remaining amount in the base station BS-D is known when the execution of the above-described resource remaining amount estimation process P2 is completed, the resource management apparatus 10 determines the resource amount for the base station BS-D. The transfer process can be executed before the time indicated by the reference “td1-dt”.

  Next, referring to FIG. 26, based on the information notified by the resource management apparatus 10 as described above, the handover according to the handover sequence for the mobile terminal UE is performed in cooperation with the base stations BS-B and BS-D. The operation for realizing is described.

  In FIG. 26, the symbol “COM1” indicates that the connection between the mobile terminal UE and the base station BS-B indicated by the same symbol in FIG. 25 is ongoing. Thereafter, before and after the predicted handover time indicated by the symbol “td1”, the mobile body V1 on which the user of the mobile terminal UE is boarding changes from the base station BS-B to the base station BS-D as illustrated in FIG. Enter the handover zone to. As the mobile object V1 moves, the mobile terminal UE detects a decrease in the reception level as indicated by a symbol P5 in FIG.

  In response to the detection of the decrease in the reception level, the mobile terminal UE transmits a message MES2 requesting a neighbor list indicating the handover destination to the connected base station BS-B. In response to reception of this message MES2, the base station BS-B, based on the information held in the above-described process P3, sends a message MES3 to hand over the mobile terminal UE to the handover destination base station BS-D. Send.

  And according to reception of this message MES3, base station BS-D performs the process P6 which allocates the resource reserved by the process P4 mentioned above to the portable terminal UE. Thereafter, the base station BS-D transmits a message MES4 including information indicating that the handover process has been started and information indicating the channel frequency allocated to the mobile terminal UE to the base station BS-B.

  In response to reception of this message MES4, the base station BS-B sends a handover instruction specifying the base station BS-D as a handover destination to the mobile terminal UE and a channel frequency notified from the base station BS-D. A message MES5 including it is transmitted.

  In response to the reception of the message MES5, the mobile terminal UE executes processing P7 for tuning the notified new channel frequency. And after completion of this process P7, connection COM2 between base stations BS-D is established.

  After establishing the connection COM2 with the mobile terminal UE in this way, the base station BS-D transmits a message MES6 that notifies the base station BS-B that the handover process has been completed. And according to reception of this message MES6, base station BS-B performs the process P8 which releases the resource allocated to the portable terminal UE.

  In this way, the mobile terminal UE can be smoothly handed over according to the handover sequence using the information notified by the resource management device 10 of the present disclosure to the base stations BS-B and BS-D.

  Of the communication procedures illustrated in FIGS. 25 and 26, the communication procedure between the mobile terminal UE and the base station BS-B and the base station BS-D is equivalent to the communication procedure in the existing wide area wireless communication network. That is, the resource management system disclosed herein can be realized without changing the communication procedure between the mobile terminal UE and the base station BS in the existing wide area wireless communication network.
