Description

Communication system, base station, and communication method

The present invention relates to a method for improving bandwidth utilization efficiency in a mobile network system, and a system for realizing the method.

Currently, smartphones account for only 12% of mobile devices used around the world, but smartphones generate 24 times more traffic than feature phones, More than 82% of the mobile terminal traffic is generated by the smartphone.

The smartphone penetration rate is expected to be 22% in Japan in March 2012 and 67% in March 2017, and traffic is expected to increase further.

In preparation for such smartphone traffic increase, mobile carriers continue to make huge capital investments, but on the other hand, more efficient capital investment and traffic reduction are required, and bandwidth utilization efficiency at peak communication traffic is required. Improvement is necessary.

Patent Document 1 discloses a mechanism that recommends smoothing of traffic by notifying all terminals of a billing mode according to time zones when the bandwidth usage of a relay line is busy. Specifically, the line monitoring node sends a message indicating that additional charging is required to continue using the line to all terminals in communication, and passes traffic related to the terminal that approves the additional charging. And discarding traffic related to a terminal that does not approve additional charging.

The following embodiment is characterized in that a terminal is identified based on the attribute information of the terminal and the traffic situation of the area formed by each base station, and communication control is performed for the identified terminal. Here, terminal attribute information is terminal-specific information such as terminal position information, speed information, action history information, and remaining battery information. As a result, it is possible to expect the traffic peaks to be dispersed temporally and spatially while improving the user satisfaction, and it is possible to improve the bandwidth utilization efficiency at the time of peak communication traffic.

The first embodiment will be described. In the first embodiment, the terminal location information, the speed information, and the communication status for each area are used to identify a terminal that is likely to move from an area where traffic is increasing to an area where traffic is low in a short period of time. A communication service providing method and a communication service providing system for providing the terminal with information that is moving toward an area with low traffic will be described.

FIG. 2 is a functional block diagram showing a schematic configuration for explaining the communication service providing method and the communication service providing system according to the first embodiment. The base station 102 </ b> A and the management server 106 are connected via the network 103.

The base station 102A records a data transmission / reception I / F 206 and a call detail information log (CDL: Call Detail Log) 202 in the storage device unit 213. In addition, a message transmission program 203, a terminal identification program 204, and a quality deterioration detection program 205 necessary for providing a communication service are provided. The CPU 211 reads and executes various programs recorded in the memory 214 to execute various functions to be described later. The same applies to other embodiments.

The management server 106 records the analysis program 207, the data transmission / reception I / F 206, and the storage device unit 213 with the terminal location information 208, the communication status 209 for each area, and the terminal speed information 210. The CPU 212 reads and executes the analysis program recorded in the memory 215, thereby executing various functions to be described later. The same applies to other embodiments.

The base station 102A periodically collects information on the terminals located for each coverage area of each radio base station. The call detail information log 202 is generated every time a terminal in the area 201 uses a telephone or mail. When the base station 102A generates such a call detailed information log 202, the terminal can receive a communication service such as a telephone call or an e-mail.

FIG. 3 is a diagram illustrating an example of the call detail information log 202 generated by the base station 102A. As shown in FIG. 3, information 301 for identifying a terminal and a user, transmission time 302, disconnection time 303, received power 304, terminal position 305, as information about the time and situation of communication, The connection destination 306, the number of received packets 307, and the communication type 308 are stored.

The detailed call information log 202 is transferred to and stored in the management server 106 connected via the network 105 via the data transmission / reception I / F 206.

FIG. 4 is a diagram showing an example of the location information 208 of each terminal configured based on the detailed call information log 202. As shown in FIG. 4, time 402, position 403, and area 404 are stored in association with information 401 for identifying a mobile terminal. As the time 402, either the transmission time or the disconnection time may be adopted. The management server holds the correspondence between the position and the area in advance, and the area 404 is set based on the terminal position 403.

FIG. 5 is a diagram showing an example of the configuration of the communication status 209 for each area, which is configured based on the call detailed information log 202. As shown in FIG. 5, time 501, area 502, throughput 503, and communication status 504 are stored in association with each other. The area 502, the throughput 503, and the communication status 504 are recorded every predetermined time, for example, every 5 minutes. The throughput 503 can be calculated from the number of received packets 307 in the call detailed information log 202 for each area 502. The display of the communication status 504 is determined based on the value of the throughput 503. For example, when the throughput is a predetermined value (for example, 2.5) or more, it is determined that the communication status is “good”, and when the throughput is less than the predetermined value, the communication status is “bad”. In addition to the binary index “good / bad” as shown in FIG.

In the management server 106, the terminal speed information 210 is created by the analysis program 207. The terminal speed information 210 indicates the moving speed of the terminal obtained from the terminal position information. The management server detects the movement of the terminal within or between areas from the time 402, position 403, and area 404 of each terminal 401 recorded in the terminal position information 208, and calculates the moving speed of the terminal by the analysis program 207. ,Record.

FIG. 6 is a diagram illustrating an example of the configuration of the terminal speed information 210 stored in the storage device unit 213 of the management server 106. As shown in FIG. 6, a time 602, a position 603, a terminal speed 604, and an area 605 are stored in association with information 601 for identifying a mobile terminal.

FIG. 7 shows the overall operation of the communication service providing method and communication service providing system of the first embodiment.

Each base station periodically obtains terminal location information 208, speed information 210, and communication status 209 for each area from the management server 106 (S701). First, based on the communication status 209 for each area, the quality deterioration detection program 205 is used to detect an area where traffic has exceeded a predetermined threshold (S702). Specifically, an area where the communication status indicated by the area-specific communication status 209 is bad is detected. Or you may detect the area where the throughput shown by the communication situation 209 according to area becomes below a predetermined value. Next, when the base station forming the detected area moves to an area with good communication status using the terminal specifying program 204 based on the terminal location information, the terminal speed information, and the traffic status of other areas. An expected terminal and an expected time required for the movement are specified (S703). Here, a terminal staying in an area where traffic is equal to or greater than a predetermined threshold is specified. With reference to the speed information, when a certain terminal is expected to move from the area to another area within a predetermined time, it is determined whether or not the communication status of the other area is good. When the communication status is good, a certain terminal is specified as a communication control target terminal. Finally, a message indicating communication suppression is transmitted to the identified terminal using the message transmission program 203 (S704). After a predetermined time, when the quality deterioration of the area is improved, the process is terminated, and when not improved, the process of S701 is repeated.

According to the method according to the form of the first embodiment, when communication traffic between the terminal and the base station increases, the terminal is identified based on the terminal position information, speed information, and traffic information inside and outside the area, A communication suppression request is notified only to the identified terminal. As a result, the terminal that has received the notification of the request can expect to refrain from communication, the traffic peak can be dispersed temporally and spatially, and the bandwidth utilization efficiency at the time of communication traffic peak can be improved. It becomes possible.

An example of notifying the specified terminal of a communication suppression request is shown in FIG. FIG. 29 shows an example of notifying a message prompting to interrupt the connection and a message indicating that the user is in an area with a poor communication status and moves to an area with a good communication status within 2 minutes. In this way, since the communication suppression information is notified for each identified terminal, it is possible to provide specific contents, and it can be expected that there is a high possibility that the communication of the terminal will be suppressed. Furthermore, the satisfaction of the user can be improved by providing information related to the improvement of the communication status useful for the user.

Further, in Patent Document 1, since notification is made to all terminals in communication, there is a possibility that the transmission traffic of notification increases and the communication traffic increases. On the other hand, in the present embodiment, since the communication suppression request is notified only to the specified terminal, the transmission traffic of the notification can be suppressed.

The second embodiment will be described. In the second embodiment, an area with low traffic for a terminal that has a high possibility of moving from an area where traffic is increasing to an area where traffic is low from the terminal position information, action history information, and communication status for each area. A communication service providing method and a communication service providing system for providing information that is moving toward the destination will be described.

In FIG. 8, the same components as those of the communication service providing method and the communication service providing system shown in FIG.

2 differs from FIG. 2 in that the management server 106 holds terminal movement tendency information 801 instead of terminal speed information.

The terminal movement tendency information 801 indicates the movement tendency of the terminal obtained from the position information of the terminal. This is calculated from the time 402, the position 403, and the area 404 for each terminal 401 recorded in the terminal position information 208. The terminal movement tendency information 801 indicates the frequency of movement of the terminal between areas at a predetermined time for weekdays and holidays or for each date.

FIG. 9 is a diagram illustrating an example of the configuration of the terminal movement tendency information 801 stored in the storage device unit 213 of the management server 106. As shown in FIG. 9, it is associated with information 901 for identifying a terminal, classified into weekdays 902 and holidays 905 for each time 908, and stored including

movement trends

903 and 906 and

frequencies

904 and 907. . The

frequencies

904 and 907 indicate the probability of moving between areas. In addition, movement trends 903 and 906 indicate information on the movement area having the highest frequency at time 908. For example, “area 1 → area 1” indicates that the user is staying in area 1. In addition, although the example classified into weekdays and a holiday was shown in FIG. 9, you may classify | categorize for every day and every day of the week.

FIG. 10 shows the overall operation of the communication service providing method and communication service providing system of the second embodiment.

Each base station periodically acquires location information 208 of terminals in the area, movement tendency information 801, and communication status 209 for each area from the management server 106 (S1001). First, based on the communication status 209 for each area, the quality deterioration detection program 205 is used to detect an area where traffic has exceeded a predetermined threshold (S1002). S1002 is the same as S702 in the first embodiment. Next, the base station that forms the detected area uses the terminal identification program 204 based on the terminal movement tendency information 801, the terminal position information, and the traffic status of other areas to make an area with a good communication status. A terminal that is expected to move within a predetermined time is identified (S1003). Here, a terminal staying in an area where traffic is equal to or greater than a predetermined threshold is specified. With reference to the terminal movement tendency information, if the frequency with which a certain terminal moves from the area to another area at that time is high, it is determined whether or not the communication status of the other area is good. When the communication status is good, a certain terminal is specified as a communication control target terminal. A message indicating communication suppression is transmitted to the identified terminal using the message transmission program 203 (S1004). After a predetermined time, when the quality deterioration of the area is improved, the process is terminated. When the area is not improved, the process is repeated from S1001.

According to the method according to the second embodiment, when the communication traffic between the terminal and the base station increases, the terminal is specified based on the terminal position information, the movement tendency information, and the traffic information inside and outside the area. The communication suppression request is notified only to the identified terminal. As a result, the terminal that has received the notification of the request can expect to refrain from communication, the traffic peak can be dispersed temporally and spatially, and the bandwidth utilization efficiency at the time of communication traffic peak can be improved. It becomes possible.

Further, the example of notifying the communication suppression request is the same as the example in FIG. 29 of the first embodiment. In this way, since the communication suppression information is notified for each identified terminal, it is possible to provide specific contents, and it can be expected that there is a high possibility that the communication of the terminal will be suppressed. Furthermore, the satisfaction of the user can be improved by providing information related to the improvement of the communication status useful for the user.

The third embodiment will be described. In the third embodiment, for a terminal that has a high possibility of moving from an area where traffic is increasing to an area where traffic is low in a short period of time based on the average stay time by area and the communication status of each area, A communication service providing method and a communication service providing system for providing information that is moving toward an area with a low level will be described.

FIG. 11 is a functional block diagram showing a schematic configuration for explaining a communication service providing method and a communication service providing system according to the third embodiment. The base station 102A and the management server 106 are connected via a network. In FIG. 11, the same components as those in the communication service providing method and the communication service providing system shown in FIG.

2 differs from FIG. 2 in that the management server 106 holds area-specific average time information 1101 instead of terminal speed information.

The average stay time information 1101 by area indicates the average length of time staying in a certain area for each terminal. This is calculated from the time 402 and the area 404 of each terminal 401 recorded in the terminal position information 208. The time during which the terminal stays in one area continuously is calculated from the analysis program 207, and the average value of the stay time for each area is calculated. In this embodiment, the average value is defined as area-specific average stay time information 1101.

FIG. 12 is a diagram showing an example of the configuration of the average staying time information 1101 for each area of the terminal stored in the storage device unit 213 of the management server 106. As shown in FIG. 6, the area 1202, the average stay time 1203, and the area 1204 to be moved next are stored in association with the information 1201 for identifying the terminal.

FIG. 13 shows the overall operation of the communication service providing method and communication service providing system of the third embodiment.

Each base station periodically acquires location information 208 of terminals in the area, average stay time information 1101 by area, and communication status 209 by area from the management server 106 (S1301). First, based on the communication status 209 by area, the quality deterioration detection program 205 is used to detect an area where traffic has exceeded a predetermined threshold (S1302). S1302 is the same as S702 of the first embodiment. Next, the base station forming the detected area has a good communication status using the terminal identification program 204 based on the average stay time information 1101 by area, the terminal location information, and the traffic status of other areas. A terminal that is expected to move to the area within a predetermined time is specified (S1303). Here, a terminal staying in an area where traffic is equal to or greater than a predetermined threshold is specified. A terminal whose average area stay time is smaller than a predetermined value is specified based on the area-specific average stay time information. Thereafter, it is determined whether or not the communication status of the area to be moved next indicated by the average stay time information by area is good. When the communication status is good, the terminal is specified as a communication control target terminal. A message indicating communication suppression is transmitted to the identified terminal using the message transmission program 203 (S1304). After a predetermined time, when the quality deterioration of the area is improved, the process is ended. When the area is not improved, the process is repeated from S1301.

According to the method according to the third embodiment, when communication traffic between the terminal and the base station increases, the terminal is based on the position information of the terminal, the average stay time information for each area, and the traffic information inside and outside the area. And the communication suppression request is notified only to the identified terminal. As a result, the terminal that has received the notification of the request can expect to refrain from communication, the traffic peak can be dispersed temporally and spatially, and the bandwidth utilization efficiency at the time of communication traffic peak can be improved. It becomes possible.

Further, the example of notifying the communication suppression request is the same as the example in FIG. 29 of the first embodiment. Thus, since the communication suppression information is notified for each identified terminal, it is possible to provide specific contents, and it can be expected that the notified information is likely to lead to terminal communication suppression. Furthermore, the satisfaction of the user can be improved by providing information related to the improvement of the communication status useful for the user.

The terminal battery remaining amount information 1402 indicates the remaining battery amount at a certain time for each terminal. This is created based on the battery remaining amount information log 1401 and the terminal position information 208. As shown in FIG. 17, the time 1702, the remaining battery charge 1703, the charging status 1704, and the area 1705 are stored in association with the information 1701 for identifying the terminal. From this information, it is possible to determine the charging point (area) for each terminal and the tendency of charging when the remaining battery level to be charged reaches.

FIG. 18 is a diagram illustrating an example of the terminal charging tendency information 1403 stored in the storage device unit 213 of the management server 106. Terminal charging tendency information 1403 indicates the charging tendency of the terminal obtained from the battery information of the terminal. The analysis program 207 calculates the charging frequency for each area from the charging status 1704 and the area 1705 for each terminal 1701 recorded in the terminal battery remaining amount information 1402. As shown in FIG. 18, each mobile terminal 1801 includes an area 1802 and a charge count 1803.

FIG. 19 shows the overall operation of the communication service providing method and communication service providing system of the fourth embodiment.

Each base station periodically receives, from the management server 106, location information 208 of terminals in the area, terminal speed information 210, terminal battery remaining amount information 1402, terminal charging tendency information 1403, and communication status 209 for each area. Obtain (S1901). First, based on the communication status 209 for each area, the quality deterioration detection program 205 is used to detect an area where the traffic exceeds a predetermined threshold (S1902). S1902 is the same as S702 in the first embodiment. Next, the base station that forms the detected area specifies a terminal with a low remaining battery level using the terminal specifying program 204 based on the terminal battery level information 1402 (S1903). Among the terminals, a terminal that is expected to move to an area with good communication status and an expected time required for the movement are specified (S1904). S1904 is the same as S703 in the first embodiment. A message indicating communication suppression is transmitted to the identified terminal using the message transmission program 203 (S1905). If the quality deterioration of the area is improved after a predetermined time, the process is terminated, and if not improved, the process is repeated from S1901.

According to the method according to the fourth embodiment, when communication traffic between the terminal and the base station increases, based on the terminal position information, speed information, battery remaining amount information, and traffic information inside and outside the area. The terminal is specified, and the communication suppression request is notified only to the specified terminal. The terminal that has received the notification of the request can expect to refrain from communication, and the traffic peak can be dispersed temporally and spatially, so that it is possible to improve the bandwidth utilization efficiency at the time of the communication traffic peak.

Furthermore, by providing information related to power efficiency improvement that is beneficial to the user, the user's satisfaction can be improved.

Moreover, in addition to S1903 and S1904, based on the terminal charging tendency information 1403, the charging point may be limited to a terminal at a far place. As a result, there is a high possibility that a terminal that has received a communication suppression request will refrain from communication, and further improvement in bandwidth utilization efficiency at the time of peak communication traffic is expected.

The fifth embodiment will be described. In the fifth embodiment, the terminal position information, the terminal speed information, the terminal contract information, the terminal cooperation history information, and the communication status for each area are terminals that often encounter traffic shortage, and are cooperative in suppressing communication. A communication service providing method and a communication service providing system for identifying a terminal, assigning points to the terminal according to the status of cooperation in reducing traffic, and prioritizing communication will be described.

In FIG. 20, the same components as those in the communication service providing method and the communication service providing system shown in FIG.

The functional block diagram of the communication service providing method and communication service providing system according to the fifth embodiment shown in FIG. 20 has a terminal contract information management server 2001, unlike FIG. The terminal contract information management server 2001 has request notification information 2002 and terminal contract information 2003. Further, the management server 106 includes a terminal-specific communication status 2004, terminal cooperation history information 2005, and contract status management 2006. .

FIG. 21 shows an example of the terminal notification information 2002. The terminal notification information 2002 includes a time 2101 when the base station notifies the terminal of a communication suppression request, a terminal 2102 that notifies the request, and an area 2103 where the terminal exists. By notifying the terminal contract information management server that the base station has made a communication suppression request notification to the terminal, request notification information 2002 is created.

FIG. 22 shows an example of the terminal contract information 2003 recorded in the terminal contract information management server 2001. The terminal contract information 2003 includes information 2201 for identifying a terminal and contract information 2202. The contract information 2202 indicates whether the terminal is subscribed to a plan that can cooperate with communication suppression. When contracted, points may be awarded each time cooperation is made, and a privilege may be provided when a certain number of points are accumulated. It is also possible to make a plan where the fee is reduced according to the number of cooperations. Alternatively, when the contract is made, the rate plan may be set to be lower than that when the contract is not made.

The terminal notification information 2002 and the terminal contract information 2003 are stored in the contract status management 2006 in the storage device 213 of the management server 106 via the network.

The communication status 2004 for each terminal indicates the communication status for each terminal configured based on the detailed call information log 202. FIG. 23 shows a configuration example of the communication status 2004 for each terminal. As shown in FIG. 23, time 2302, throughput 2303, and area 2304 are stored in association with information 2301 for identifying a terminal. Throughput 2303 can be calculated from the number of received packets 307 in the call detail information log 202.

The terminal cooperation history information 2005 indicates whether or not each terminal has cooperated in reducing traffic in an area where traffic shortage has been encountered. This is created based on the request notification time 2101 of the request notification information 2002, the terminal 2102 that notified the request, the area 2103 where the terminal stays, and whether or not the terminal cooperated with the request notification. . In order to grasp the cooperation status of the terminal, after notifying the cooperation request, it is determined that the terminal has cooperated by sending a message indicating that the terminal cooperated with the request to the management server via the base station. . Or after notifying a cooperation request, you may judge that it cooperated when it detects that the throughput has decreased remarkably within a fixed period.

FIG. 24 shows an example of terminal cooperation history information 2005 stored in the storage device unit 213 of the management server 106. As shown in FIG. 24, information 2401 for identifying a terminal, request notification time 2402, area 2403, and cooperation status 2404 are stored.

FIG. 25 shows the overall operation of the communication service providing method and communication service providing system of the fifth embodiment.

Each base station periodically receives location information 208 of terminals in the area, terminal speed information 210, communication status by terminal 2004, terminal cooperation history information 2005, contract status management 2006, and communication by area from the management server 106. The situation 209 is acquired (S2501). First, based on the communication status 209 for each area, the area where the traffic exceeds a predetermined threshold is detected using the quality degradation detection program 205 (S2502). S2502 is the same as S702 of the first embodiment. Next, the base station that forms the detected area identifies a terminal that is expected to move to an area with good communication status (S2503). S2503 is the same as S703 in the first embodiment.

Also, the terminal of the plan in which the cooperation is included in the contract is specified based on the terminal contract information 2003 among the terminals (S2504). Further, based on the terminal cooperation history information, the terminal identification program 204 is used to identify a terminal whose accumulated points of terminals that cooperated in the request are within a predetermined range (S2505). This is because a privilege is provided when a certain point is accumulated, and a terminal that is expected to be cooperative in communication suppression is specified. A message indicating communication suppression is transmitted to the identified terminal using the message transmission program 203 (S2506). If the quality deterioration of the area is improved after a predetermined time, the process is terminated, and if not improved, the process is repeated from S2501.

According to the method according to the fifth embodiment, when the communication traffic between the terminal and the base station increases, the terminal position information, speed information, contract information, cooperation history information, and the communication status for each area Based on this, the terminal is specified, and the communication suppression request is notified only to the specified terminal. The terminal that has received the notification of the request can expect to refrain from communication, traffic peaks can be dispersed temporally and spatially, and bandwidth utilization efficiency at the time of communication traffic peaks can be improved. .

FIG. 31 shows an example of notifying the specified terminal of a communication suppression request. FIG. 31 shows an example in which a message for instructing the interruption of the connection and a message for notifying the provision of the privilege service with 80 points for cooperation integration points and another 20 points. In this way, since the communication suppression information is notified for each identified terminal, it is possible to provide specific contents, and it can be expected that there is a high possibility that the communication of the terminal will be suppressed. Furthermore, the satisfaction of the user can be improved by providing information related to privilege services useful for the user.

In S2504, the terminals that cooperated in the previous cooperation request may be excluded. This makes it possible to specify, on average, terminals that are subject to notification of communication suppression requests among contracted terminals. In S2503, the terminal-specific communication status 2004 may be used to identify a terminal in an area where the frequency of throughput being slow is high.

The sixth embodiment will be described. In the sixth embodiment, the terminal location information, the terminal speed information, the event information, and the communication status of each area indicate that the event is being performed on the terminal in the area where the event is present, and the communication efficiency is low. A communication service providing method and a communication service providing system will be described that provide a terminal moving toward a lower area with communication efficiency being better when communication is performed at the destination. The target of this service is a person who visited the event.

FIG. 26 is a functional block diagram illustrating a schematic configuration for explaining the communication service providing method and the communication service providing system according to the sixth embodiment. In FIG. 26, the same components as those in the communication service providing method and the communication service providing system shown in FIG.

The functional block diagram of the communication service providing method and communication service providing system according to the sixth embodiment shown in FIG. 26 has an event management server 2601 unlike FIG. The event management server 2601 has event information 2602. Furthermore, the management server 106 has event information management 2603.

The event information 2602 is acquired in cooperation with a company providing a service for notifying an event or a company selling an event ticket, and the event information 2602 is stored in the storage device unit 213 of the management server 106. It is stored as information management 2603.

FIG. 27 is a diagram illustrating an example of event information management 2603 stored in the storage device unit 213 of the management server 106. As shown in FIG. 27, information 2701 for identifying an area, a scheduled event start time 2702, a scheduled event end time 2703, and an event scale (scheduled incoming customer number) 2704 are stored.

FIG. 28 shows the overall operation of the communication service providing method and communication service providing system of the sixth embodiment.

Each base station periodically acquires the communication status by area from the management server 106. Based on the communication status by area, the area where the traffic exceeds a predetermined threshold is detected using the quality degradation detection program 205 (S2801). S2801 is the same as S702 in the first embodiment. Next, the base station forming the detected area detects that there is an event from the event information management 2603 and further acquires detailed information on the event (S2802). Further, the location information 208 of the terminal in the area and the communication status 209 for each area are acquired from the management server 106 (S2803).

Based on the acquired information, the terminal identification program 204 is used to exclude terminals that spend a lot of time in an area where there is an event. This step is a process for distinguishing whether the person has visited the event or not (S2804). This step specifies and excludes terminals that stay in the area where the event takes place for a predetermined time or longer based on the terminal position information.

Based on the acquired information, the terminal identifying program 204 is used to identify a terminal that spends less time in the area where the event is located. This step is a process for specifying an object to provide a service (S2805). In this step, a terminal whose time in an area where an event is held is less than a predetermined value is specified from the terminal position information, and a terminal whose speed is a predetermined value or more is specified. By this process, it is possible to identify a terminal that is highly likely to leave the area where the event is performed. A message indicating communication suppression is transmitted to the identified terminal using the message transmission program 203 (S2806). If the quality deterioration of the area is improved after a predetermined time, the process is terminated, and if not improved, the process is repeated from S2803.

According to the method according to the sixth embodiment, when communication traffic between the terminal and the base station increases, the terminal location information, terminal speed information, event information, and the communication status for each area And the communication suppression request is notified only to the identified terminal. The terminal that has received the notification of the request can expect to refrain from communication, traffic peaks can be dispersed temporally and spatially, and bandwidth utilization efficiency at the time of communication traffic peaks can be improved. .

FIG. 32 shows an example of notifying the specified terminal of a communication suppression request. FIG. 32 shows an example in which event information is notified together with a message for prompting connection interruption. In this way, since the communication suppression information is notified for each identified terminal, it is possible to provide specific contents, and it can be expected that there is a high possibility that the communication of the terminal will be suppressed. Furthermore, it can be notified that the vehicle is moving toward an area with low traffic. By providing information related to communication status improvements that are beneficial to the user, it is possible to improve user satisfaction.

In the above embodiments, an example has been described in which the base station detects communication quality deterioration in an area due to excessive traffic and identifies a terminal for which communication is to be suppressed. However, these functions can also be realized by a management server. It is.
