Description

  The present invention relates to a wireless communication system.

  Currently, the spread of mobile phones and smartphones is expanding. As the use of mobile phones and smartphones increases, resources in the base station (evolved NodeB: eNB) and the core network may become tight due to simultaneous transmission from user equipment (User Equipment: UE), which may cause congestion. . For this reason, in the LTE (Long Term Evolution) network, access restriction control (Access Class Barring: ACB) for restricting access requests from user apparatuses is introduced.

  In typical access restriction control, an access class is assigned to all user apparatuses located in a base station, and transmission of a connection request from the user apparatus is controlled based on the access class. For example, the base station transmits an access class subject to access restriction and restriction information (regulation rate, restriction time, etc.) to the user apparatus as broadcast information (System Information Block 2: SIB2). When receiving the notification information, the user apparatus determines whether or not the user apparatus is subject to access restriction. If the user apparatus is subject to access restriction, the user apparatus stops sending a connection request signal to the base station.

  Such ACB regulations are typically in high traffic areas such as homes, ticket gates, predetermined areas such as station stairs, and predetermined times and areas where events such as fireworks displays and demonstrations are held. To be implemented.

3GPP TS 36.331 V12.1.0 (2014-03)

  On the other hand, in such high-traffic areas, user devices with usage conditions that are generally considered to be less urgent, such as smartphone operations while walking (so-called walking smartphones) and multimedia content downloads, will communicate excessively. There is a possibility that a congestion state has occurred.

  However, in the conventional access restriction control, as shown in FIG. 1, the access restriction cannot be performed according to the use situation of the user device, and the user device in such a less urgent use situation is excessive. Because of communication, a user device that truly needs communication cannot connect to the network, and the wireless communication service cannot be used. In particular, walking smartphones are considered to have safety problems not only in terms of congestion, but also in certain areas such as station platforms and intersections. For this reason, it is considered useful not only to avoid the congestion state, but also to regulate the use situation with safety problems.

  In view of the above-described problems, an object of the present invention is to provide a technique for realizing access restriction control according to the usage status of a user device.

  In order to solve the above-described problem, an aspect of the present invention provides an access restriction information receiving unit that receives access restriction information indicating a use state of a user device that is subject to access restriction from a base station, and a use state of the user device And a user device having an access restriction execution unit that autonomously executes the access restriction when the user device is determined to be subject to the access restriction based on the detected use state About.

  Another aspect of the present invention provides an access restriction control unit that activates access restriction for a user device in a specific usage situation in response to detection of an access restriction trigger for implementing access restriction; The present invention relates to a base station having an access restriction execution unit that receives use state information indicating a use state and determines whether to apply the access restriction to the user apparatus based on the received use state information.

  According to the present invention, it is possible to realize access restriction control according to the usage status of the user device.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  In an embodiment to be described later, a user apparatus and a base station that realize access restriction for a user apparatus in a specific usage situation are disclosed.

  In summary, in the first embodiment, the user apparatus autonomously performs access restriction based on the access restriction information received from the base station. That is, when the base station activates the access restriction, the user device determines its own usage situation, and the judged usage situation corresponds to the usage situation of the access regulation target indicated in the access regulation information transmitted from the base station , Autonomously restrict access. For example, as shown in FIG. 2, when access restriction information indicating that a walking smartphone is subject to access restriction is received from the base station as notification information, the user apparatus detects its own usage status and enters the walking smartphone state. In some cases, communication with the base station is regulated autonomously.

  In the second embodiment, the base station performs access restriction on the user device based on the usage status reported from the user device. That is, when the access restriction is activated, the base station acquires usage status information from the user device, and when the usage status of the user device corresponds to the usage status subject to access regulation, rejects the access request from the user device, or , Interrupt the ongoing communication. For example, as illustrated in FIG. 3, the base station acquires usage status information from a user device that has requested access, and if the usage status of the user device corresponds to a walking smartphone that is subject to access control, the base station Reject the access request.

  As a result, it is possible not only to avoid a congestion state, but also to restrict the use of a wireless communication service by a user device in a usage situation that has a safety problem.

  A wireless communication system according to an embodiment of the present invention will be described with reference to FIG. FIG. 4 is a schematic diagram illustrating a wireless communication system according to an embodiment of the present invention.

  As illustrated in FIG. 4, the wireless communication system 10 includes user apparatuses 100 and 200 and base stations 300 and 400. For convenience of explanation, the user apparatus 100 and the base station 300 correspond to the first embodiment described above, and the user apparatus 200 and the base station 400 correspond to the second embodiment described above. Typically, as illustrated, a plurality of user apparatuses 100 and 200 are wirelessly connected to base stations 300 and 400. In the illustrated embodiment, only one base station 300, 400 is shown, but typically a large number of base stations 300, 400 are arranged to cover the communication area of the wireless communication system 10.

  As illustrated, the user devices 100 and 200 may be any appropriate information processing device having a wireless communication function such as a smartphone, a mobile phone, a tablet, or a wearable terminal. User devices 100 and 200 include a CPU (Central Processing Unit) such as a processor, a memory device such as a RAM (Random Access Memory) and a flash memory, a communication circuit for transmitting and receiving radio signals to and from the base stations 300 and 400, It includes a user interface for user input / output, various sensors such as an inclination sensor and an acceleration sensor, a GPS (Global Positioning System) circuit, an imaging means such as a camera, and the like. Each function and process of the user devices 100 and 200 to be described later may be realized by the CPU processing or executing data or a program stored in the memory device. However, the user devices 100 and 200 are not limited to the hardware configuration described above, and may be configured by a circuit that realizes one or more of the processes described below.

  The base stations 300 and 400 wirelessly connect to the user apparatuses 100 and 200 to receive downlink (DL) packets received from network apparatuses such as upper stations and servers that are communicatively connected to a core network (not shown). While transmitting to user apparatus 100,200, the uplink (UL) packet received from user apparatus 100,200 is transmitted to a network apparatus. The base stations 300 and 400 typically include an antenna for transmitting and receiving radio signals to and from the user apparatuses 100 and 200, a communication interface for communicating with the core network, and between the user apparatuses 100 and 200 and the core network. It is comprised by hardware resources, such as a processor and a circuit for processing the transmission / reception signal between. Each function and process of the base stations 300 and 400, which will be described later, may be realized by a processor processing or executing data or a program stored in a memory device. However, the base stations 300 and 400 are not limited to the hardware configuration described above, and may have any other appropriate hardware configuration.

  Next, an access restriction process according to the first embodiment of the present invention will be described with reference to FIGS. In the first embodiment of the present invention, the user apparatus 100 autonomously restricts access based on the access restriction information received from the base station 300. That is, when access restriction is activated, the user apparatus 100 determines its own usage situation, and the determined usage situation corresponds to the usage situation of the access restriction target indicated in the access restriction information transmitted from the base station 300. If so, implement access control autonomously.

  FIG. 5 is a block diagram showing a configuration of a user apparatus according to the first embodiment of the present invention. As illustrated in FIG. 5, the user device 100 includes an access restriction information receiving unit 110, a usage state detection unit 120, and an access restriction execution unit 130.

  The access restriction information receiving unit 110 receives access restriction information indicating the usage status of the user apparatus 100 that is the target of access restriction from the base station 300. In one embodiment, the access restriction information is notified as broadcast information from the base station 300 that has activated the access restriction, and the access restriction information receiving unit 110 extracts the access restriction information from the received broadcast information. The access restriction information indicates the use state of the user device 100 that is subject to access restriction. For example, the use state of the user device 100 such as “walking state” or “mass data download state”, the “ It may indicate a user attribute such as “sex” or “age”, a “device type” of the user device 100 such as a wearable terminal, or any combination thereof. Here, the “walking state” state is a state in which the user device 100 is walking, and the “mass data download state” is a state in which data of a predetermined amount or more is being downloaded.

  Note that the access restriction information does not necessarily have to be notified as notification information, and may be individually transmitted to the user apparatus 100 as control information. For example, when the user apparatus 100 is communicating with the base station 300, the access restriction information may be included in control information transmitted from the base station 300 to the user apparatus 100.

  The usage status detection unit 120 detects the usage status of the user device 100. For example, the usage status detection unit 120 may determine one or more of a movement state, a communication amount, a user attribute, and a device type. In one embodiment, the usage status detection unit 120 may detect a parameter related to the usage status of the access restriction target indicated in the access restriction information. When the “walking state” is an access restriction target, the usage state detection unit 120 detects whether the user device 100 is in the walking state. The walking state can be detected by, for example, an acceleration sensor mounted on the user apparatus 100, or the number of cells in which the user apparatus 100 has been located, the cell type (macro cell or pico cell), and the presence in each cell. It can be detected by the time zone. In addition, when the “mass data download state” is an access restriction target, the usage state detection unit 120 determines whether the user device 100 is downloading data of a predetermined amount or more. In addition, when access control based on user attributes related to “gender” and / or “age” is activated, the usage status detection unit 120 determines “sex” and / or from the user attribute information stored in the user device 100. “Age” may be detected. Further, when the “apparatus type” is an access restriction target, the usage status detection unit 120 may detect the “apparatus type” from the apparatus information stored in the user apparatus 100.

  When the access restriction enforcement unit 130 determines that the user device 100 is subject to access restriction based on the detected usage status, the access restriction enforcement unit 130 autonomously implements access restriction. Here, the implementation of autonomous access control means that the user apparatus 100 voluntarily interrupts communication with the base station 300 or refrains from connection requests. Specifically, when the usage status of the access regulation target indicated in the access regulation information is “walking state”, when the usage status detection unit 120 detects that the user device 100 is “walking state”, the access regulation is performed. The implementation unit 130 determines that the user device 100 is subject to access regulation, and implements access regulation such as voluntarily interrupting communication or refraining from connection requests. On the other hand, when the usage status detection unit 120 detects that the user device 100 is not in the “walking state”, the access regulation execution unit 130 determines that the user device 100 is not subject to access regulation and implements autonomous access regulation. The communication is continued or the connection request signal is transmitted.

  In one example, if the access restriction enforcement unit 130 determines that the user device 100 is subject to access restriction, the access restriction enforcement unit 130 may display to the user that the access restriction is being implemented. For example, as illustrated in FIG. 6, the access restriction performing unit 130 may perform the access restriction and display a message indicating that the access restriction has been performed on the display of the user device 100 or the like. In the display example on the left side of FIG. 6, the access restriction execution unit 130 urges the user to stop walking from the viewpoint of safety. On the other hand, in the display example on the right side, the access restriction execution unit 130 indicates that communication is interrupted by the user from the viewpoint of congestion. In this way, in order to display different types of messages on the user apparatus 100, the base station 300 includes the access restriction information in the access restriction information (such as “walking state”) and the reason for access restriction (“safety”). Viewpoint ”,“ congestion viewpoint ”, and the like). The access restriction execution unit 130 may display a message corresponding to the notified reason for access restriction.

  In one embodiment, the usage statuses of a plurality of access restriction targets may be indicated in the access restriction information. For example, when the usage statuses of two access restriction targets “walking state” and “wearable terminal” are indicated, the access restriction execution unit 130 indicates that the user device 100 is a “wearable terminal” and the “walking state”. If so, access control is implemented autonomously. From the viewpoint of safety, when the usage status of two access restriction targets “walking state” and “wearable terminal” is indicated, the access restriction enforcement unit 130 has no safety problem such as a call function and a music playback function. The function may be made available outside the access restriction. Further, in another embodiment, the access restriction enforcement unit 130 has one or more services (video playback and map) having a communication amount equal to or greater than a predetermined threshold for a specific “device type” such as “wearable terminal”. You may implement access restrictions that do not allow display etc. to be used at the same time. As described above, the access restriction execution unit 130 may selectively restrict access to the wireless communication service according to the use state of the access restriction target and / or the reason for the access restriction.

  FIG. 7 is a block diagram illustrating a configuration of a base station according to the first embodiment of the present invention. As illustrated in FIG. 7, the base station 300 includes an access restriction control unit 310 and an access restriction information notification unit 320.

  In response to detection of an access restriction trigger for implementing access restriction, the access restriction control unit 310 activates access restriction for the user device 100 in a specific usage situation. The access restriction trigger is, for example, an instruction from a higher station or a network administrator, that a predetermined amount of traffic is detected in a predetermined area and / or a predetermined time, or a predetermined number of user devices 100 in a predetermined area. May be detected. Specifically, when an event where a large number of users gather, such as a fireworks display or a demonstration, is held, the access restriction control unit 310 activates access restriction in response to an instruction from a higher station or a network administrator. Also good. Further, the access restriction control unit 310 detects a predetermined amount of traffic in a predetermined area and / or a predetermined time, or detects a predetermined number or more user devices 100 in a predetermined area. In response to detecting the restriction trigger, access restriction may be activated autonomously.

  In one embodiment, the access restriction control unit 310 may determine the user device 100 that is subject to access restriction according to the type of the detected access restriction trigger. For example, when the access restriction trigger is an instruction from an upper station or a network administrator, the user device 100 corresponding to the use state of the access restriction object indicated in the instruction may be determined as the access restriction object. For example, when the network administrator instructs the user device 100 in the “walking state” to perform access restriction, the access restriction control unit 310 determines the user device 100 in the “walking state” as an access restriction target. Also good. Alternatively, when the access restriction trigger is that a predetermined amount or more of traffic is detected in a predetermined area and / or a predetermined time, or a predetermined number or more of user devices 100 are detected in the predetermined area, the access restriction control. The unit 310 may determine the user device 100 corresponding to the “walking state” or the “mass data download state” as an access restriction target in order to reduce congestion.

  As described above, the access restriction control unit 310 may determine the user device 100 that is subject to access restriction based on one or more of the movement state, communication amount, user attribute, and device type of the user device 100. For example, the access restriction control unit 310 may determine the user device 100 in a walking state as an access restriction target. Alternatively, the access restriction control unit 310 may determine, as an access restriction target, the user device 100 that is downloading data of a predetermined amount or more. Further, the access restriction control unit 310 may determine the user device 100 of a young user as an access restriction target in an area where young people gather. Alternatively, the access restriction control unit 310 may determine the user device 100 of the elderly user as an access restriction target in an area that is dangerous for the elderly such as a platform of a station or a staircase. Further, the access restriction control unit 310 may determine the user device 100 of a specific device type as an access restriction target. For example, the access restriction control unit 310 may determine the head mounted display type user device 100 such as Google Glass as an access restriction target.

  The access restriction information notification unit 320 notifies access restriction information indicating the usage status of the user device 100 that is the target of access restriction. In one embodiment, the access restriction information notifying unit 320 may notify the access restriction information as notification information. The access restriction information indicates the usage status of the user device 100 that is subject to the access regulation determined by the access regulation control unit 310. For example, the usage of the user device 100 such as “walking state” or “mass data download state” is used. It may indicate the status, user attributes such as “gender” and “age” of the user of the user device 100, device type such as “wearable terminal”, or any combination thereof.

  FIG. 8 is a sequence diagram showing access restriction processing according to the first embodiment of the present invention. The access restriction process is started when an access restriction trigger is detected in the base station 300.

  As illustrated in FIG. 8, in step S101, the base station 300 transmits access restriction information indicating a use situation that is subject to access restriction to the user apparatus 100. In one embodiment, the base station 300 may notify the access restriction information as notification information in order to notify all the user apparatuses 100 in the area all at once.

  When the access restriction information is received, in step S102, the user device 100 detects the usage status of the user device 100. In one embodiment, the user device 100 detects a usage status of a type corresponding to a usage status that is an access restriction target indicated in the received access restriction information. For example, when the “walking state” is an access restriction target, the user device 100 determines whether the user device 100 is communicating in the walking state using an acceleration sensor mounted on the user device 100. Alternatively, when “age” is an access restriction target, the user device 100 refers to the user attribute information stored in the user device 100 and identifies the “age” of the user.

  In step S <b> 103, the user apparatus 100 determines whether or not the user apparatus 100 is subject to access restriction based on the detected usage status. Specifically, the user device 100 determines whether the detected usage status corresponds to the usage status of the access restriction target indicated in the received access restriction information.

  If it is an access restriction target, in step S104, the user apparatus 100 autonomously implements access restriction. Specifically, the user device 100 may voluntarily interrupt the ongoing communication or may not accept a connection request instruction from the user. While implementing access restriction, the user apparatus 100 may notify the user that access restriction is being implemented.

  On the other hand, when not subject to access restriction, in step S105, the user apparatus 100 transmits a connection request signal to the base station 300 or continues the ongoing communication.

  Next, an access restriction process according to the second embodiment of the present invention will be described with reference to FIGS. In the second embodiment of the present invention, the base station 400 performs access restriction on the user apparatus 200 based on the usage status reported from the user apparatus 200. That is, when the access restriction is activated, the base station 400 acquires usage status information from the user apparatus 200, and when the usage status of the user apparatus 200 corresponds to the usage status subject to access regulation, an access request from the user apparatus 200 is received. Or the ongoing communication is interrupted.

  FIG. 9 is a block diagram illustrating a configuration of a base station according to the second embodiment of the present invention. As shown in FIG. 9, the base station 400 includes an access restriction control unit 410 and an access restriction execution unit 420.

  In response to detection of an access restriction trigger for implementing access restriction, the access restriction control unit 410 activates access restriction on the user device 200 in a specific usage situation. The access restriction trigger is, for example, an instruction from a higher station or a network administrator, that a predetermined amount of traffic is detected in a predetermined area and / or a predetermined time, or a predetermined number of user devices 100 in a predetermined area. May be detected. Specifically, when an event where a large number of users gather, such as a fireworks display or a demonstration, is held, the access restriction control unit 410 may activate access restriction in response to an instruction from a higher station or a network administrator. Good. Further, the access restriction control unit 410 detects a predetermined amount of traffic in a predetermined area and / or a predetermined time, or detects a predetermined number of user devices 200 in a predetermined area. In response to detecting the restriction trigger, access restriction may be activated autonomously.

  In one embodiment, the access restriction control unit 410 may determine the user device 200 that is subject to access restriction according to the type of the detected access restriction trigger. For example, when the access restriction trigger is an instruction from an upper station or a network administrator, the user device 200 corresponding to the use state of the access restriction object included in the instruction may be determined as the access restriction object. Alternatively, when the access restriction trigger is that a predetermined amount or more of traffic is detected in a predetermined area and / or a predetermined time, or a predetermined number or more of user devices 200 are detected in the predetermined area, the access restriction control The unit 410 may determine the user device 200 corresponding to the “walking state” or the “mass data download state” as an access restriction target in order to reduce congestion.

  In one embodiment, the access restriction control unit 410 may determine the user device 200 that is subject to access restriction based on one or more of the movement state, the traffic, the user attribute, and the device type. For example, the access restriction control unit 410 may determine the user device 200 in a walking state as an access restriction target. Alternatively, the access restriction control unit 410 may determine, as an access restriction target, the user device 200 that has downloaded data of a predetermined amount or more. Furthermore, the access restriction control unit 410 may determine the user device 200 of a young user as an access restriction target in an area where young people gather. Alternatively, the access restriction control unit 410 may determine the user device 200 of the elderly user as an access restriction target in an area that is dangerous for the elderly such as a platform of a station or a staircase. Further, the access restriction control unit 410 may determine the user device 200 of a specific device type as an access restriction target. For example, the access restriction control unit 410 may determine a head-mounted display type user device 200 such as Google Glass as an access restriction target.

  The access restriction execution unit 420 receives usage status information indicating the usage status of the user device 200 and determines whether to apply access control to the user device 200 based on the received usage status information. Specifically, in the access restriction execution unit 420, the usage status of the user device 200 indicated in the usage status information received from the user device 200 corresponds to the usage status of the access restriction target determined by the access restriction control unit 410. If the usage status of the user device 200 is an access restriction target, the access restriction is applied to the user device 200.

  In one embodiment, when it is determined that the access restriction is applied to the user device 200, the access restriction enforcement unit 420 may reject the connection request from the user device 200. Alternatively, when the user device 200 is communicating with the base station 400, the access restriction execution unit 420 may interrupt communication with the user device 200.

  In one example, when the access restriction execution unit 420 determines that the user device 200 is subject to access restriction, the access restriction execution unit 420 may cause the user device 200 to display that the access restriction is being executed. Further, as illustrated in FIG. 6, the access restriction execution unit 420 may include the reason for access restriction (“safety viewpoint”, “congestion viewpoint”, etc.) along with the access restriction. Thereby, the user apparatus 200 may display a message corresponding to the notified reason for access restriction. Further, the access restriction execution unit 420 may selectively restrict the access to the wireless communication service for the user apparatus 200 according to the use situation of the access restriction target and / or the reason for the access restriction. Further, the access restriction execution unit 420 may reject the connection request and notify the user apparatus 200 of the waiting time until the access is started. After the standby time has elapsed, the access restriction execution unit 420 may permit the connection request for the user device 200.

  On the other hand, when the usage status of the user device 200 is not an access restriction target, the access restriction execution unit 420 permits a connection request from the user device 200 or continues communication with the user device 200.

  In one embodiment, the user apparatus 200 notifies a connection establishment request signal at the time of transition from the idle state to the connected state, or in response to a report instruction from the base station 400 or periodically detects the usage status, The detected usage status may be reported to the base station 400 using the usage status information.

  In one embodiment, the access restriction enforcement unit 420 may cause the user device 200 to report parameters related to the access restriction target usage status. For example, when the “walking state” is an access restriction target, the access restriction execution unit 420 may cause the user device 200 to report the walking speed or the number of cells that have been in the area within a predetermined period. .

  FIG. 10 is a block diagram showing a configuration of a user apparatus according to the second embodiment of the present invention. As illustrated in FIG. 10, the user device 200 includes a usage status detection unit 210 and a usage status report unit 220.

  The usage status detection unit 210 detects the usage status of the user device 200. For example, the usage status detection unit 210 may determine one or more of the movement state, communication amount, user attribute, and device type of the user device 200. In one embodiment, the usage status detection unit 210 may detect a parameter related to the usage status of the access restriction target notified from the base station 400. When the “walking state” is an access restriction target, the usage state detection unit 210 detects whether the user device 200 is in a walking state. The walking state can be detected by, for example, an acceleration sensor mounted on the user apparatus 200, or can be detected by the number of cells in which the user apparatus 200 has been within a predetermined period. When the “large amount data download state” is an access restriction target, the usage state detection unit 210 determines whether the user device 200 is downloading data of a predetermined amount or more. In addition, when access control based on user attributes relating to “gender” and / or “age” is activated, the usage status detection unit 210 extracts user attribute information stored in the user device 200. When the “device type” is the access restriction target, the usage status detection unit 210 may detect the “device type” from the device information stored in the user device 200.

  The usage status information report unit 220 transmits usage status information indicating the usage status of the user apparatus 200 to the base station 400. In one embodiment, the usage status information reporting unit 220 notifies the connection probability request signal at the time of transition from the idle state to the connected state, and in response to a report instruction from the base station 400 or periodically. Usage status information indicating the status may be reported to the base station 400.

  FIG. 11 is a sequence diagram showing access restriction processing according to the second embodiment of the present invention. The access restriction process is started when an access restriction trigger is detected in the base station 400.

  As illustrated in FIG. 11, in step S201, the base station 400 activates access restriction on the user apparatus 200 in a specific usage situation. In one embodiment, the base station 400 may determine the user equipment 200 that is subject to access restriction according to the detected type of access restriction trigger.

  In step S202, the base station 400 acquires usage status information from the user apparatus 200. In one embodiment, the user apparatus 200 notifies the connection establishment request signal at the time of transition from the idle state to the connected state, or in response to a report instruction from the base station 400 or periodically, the detected usage status. The usage status information shown may be reported to the base station 400.

  In step S203, the base station 400 determines whether the user device 200 is subject to access restriction based on the received usage status of the user device 200. Specifically, the base station 400 determines whether the usage status of the user device 200 corresponds to an access restriction target.

  If the user apparatus 200 is subject to access restriction, the base station 400 performs access restriction on the user apparatus 200 in step S204, and rejects to reject the connection request from the user apparatus 200 in step 205. A signal is transmitted, or a signal for interrupting communication performed with the user apparatus 200 is transmitted. On the other hand, when the user apparatus 200 is not subject to access restriction, the base station 400 transmits a permission signal for permitting a connection request from the user apparatus 200 or communication performed with the user apparatus 200. Continue.
