Description

  The present invention relates to a universal mobile telephony service (UMTS) and a long term evolution (LTE) system, and more particularly to a communication control device, a mobile station device, a mobile communication system, and a communication control method.

  A communication method succeeding W-CDMA and HSDPA (generic name UMTS), that is, LTE (Long Term Evolution) has been studied by the UMTS standardization organization 3GPP. As for the uplink, SC-FDMA (Single-Carrier Frequency Multiple Access) has been studied (for example, see Non-Patent Document 1).

  In the UMTS system, restrictions are classified into cell restrictions (Cell Restrictions) and access restrictions (Access Restrictions) (see, for example, Non-Patent Document 2).

  Note that the above two types of restrictions are set by notification information. Specifically, it is set by SIB (System Information Block) 3/4.

  In the case of cell regulation, the mobile station device cannot be located in the cell. Therefore, the mobile station apparatus located in the area covered by the cell must select another cell. Cell regulation is used when a problem occurs in a cell or when maintenance of a network device is performed.

  Access restrictions are set according to the Access Class Barred List (list with restrictions for each access class, without restrictions) set in the broadcast information and the access classes held in the USIM (universal subscriber identity module) of the mobile station apparatus. Or, incoming calls are restricted. Access restrictions are used to reduce network load when communication traffic increases and the network is loaded.

  There are 16 types of access classes 0 to 15 held in the USIM (see, for example, Non-Patent Document 3). Of 0-15, 0-9 is randomly assigned to general users, 10 is assigned to emergency calls, not users, 11 is assigned to PLMN (Public Land Mobile Network) specific users, and 12 is assigned to emergency users. Allocated for security service users, 13 allocated for public users, 14 allocated for emergency users, and 15 allocated for PLMN staff users.

When changing the content of the broadcast information, it is necessary to transmit paging and notify the mobile station apparatus. In the case of changing the content of the notification information, the case of changing from no regulation to regulation is included.
3GPP TR 25.814 (V7.0.0), "Physical Layer Aspects for Evolved UTRA," June 2006 3GPP TS 25.304 3GPP TS 22.001 3GPP TS 25.331

  In the access restriction, each access class is set to be restricted (barred) or not restricted (not barred). For example, in the access restriction, the above setting is performed in order to control the total amount of network calls (see, for example, Non-Patent Document 4).

  However, in the current system, inequality occurs between access classes. In other words, access regulation is uneven among access classes. For example, when access restriction is set to access class 0, a user having access class 0 is restricted, and a user having access class 1-15 is not restricted.

  In UMTS, general users, ie users with access classes 0-9, have the same priority. However, for the above reasons, access restrictions are unequal (non-uniform).

  In order to control the total call volume of the network and restrict access to the general users equally, consider changing access rules for access classes 0-9 periodically and distributing the access controls to be equal. is required. However, in that case, it is necessary to transmit paging each time the content of regulation is changed, and radio resources are wasted. Here, paging is used to mean calling a mobile station apparatus, and includes not only layer 3 (L3) paging used in the UMTS system but also a message equivalent to calling in the LTE system.

  According to the embodiment of the present invention, it is possible to realize a communication control device, a mobile station device, a mobile communication system, and a communication control method capable of equalizing access control among users having the same priority.

  According to the embodiment of the present invention, it is possible to realize a communication control device, a mobile station device, a mobile communication system, and a communication control method that can reduce paging transmission for changing notification information related to access restriction.

Next, the best mode for carrying out the present invention will be described based on the following embodiments with reference to the drawings.
In all the drawings for explaining the embodiments, the same reference numerals are used for those having the same function, and repeated explanation is omitted.

  A radio communication system to which a communication control apparatus and a mobile station apparatus according to an embodiment of the present invention are applied will be described with reference to FIG. In the present embodiment, a system to which LTE (Long Term Evolution) is applied will be described as an example. However, a system to which UMTS (universal mobile telephone service) is applied, specifically, a system to which W-CDMA or HSDPA is applied. It can also be applied to. In general, the present invention is applicable to any wireless communication system that transmits control information of a mobile station device corresponding to broadcast information from a base station and performs control according to information corresponding to the priority and access class on the mobile station device side. is there.

The radio communication system 1000 is a system to which, for example, Evolved UTRA and UTRAN (also known as Long Term Evolution, or Super 3G) is applied, and includes a base station apparatus (eNB: eNode B) 200 and a plurality of mobile station apparatuses (MS: mobile Station) 100 _n (100 ₁ , 100 ₂ , 100 ₃ ,... 100 _n , n is an integer of n> 0). Base station apparatus 200 is connected to an upper station apparatus, for example, access gateway apparatus 300, and upper station apparatus 300 is connected to core network 400. Here, the mobile station device 100 _n communicates with the base station device 200 by the Evolved UTRA and UTRAN in the cell 50.

Hereinafter, since the mobile station apparatus 100 _n (100 ₁ , 100 ₂ , 100 ₃ ,... 100 _n ) has the same configuration, function, and state, the mobile station apparatus 100 _n will be described below unless otherwise specified. As the explanation proceeds. For convenience of explanation, the mobile station device communicates with the base station device wirelessly, but more generally, a user device (UE: User Equipment) including both a mobile terminal and a fixed terminal may be used.

  Radio communication system 1000 employs OFDM (frequency division multiple access) for the downlink and SC-FDMA (single carrier frequency division multiple access) for the uplink as the radio access scheme. OFDM is a scheme in which a frequency band is divided into a plurality of narrow frequency bands (subcarriers) and data is transmitted on each frequency band. SC-FDMA is a transmission method that can reduce interference between terminals by dividing a frequency band and performing transmission using different frequency bands among a plurality of terminals.

An access gateway device (aGW: access gateway) 300 may be provided in, for example, the core network 400, or may be provided in a network other than the core network 400. The access gateway device may be divided into logical entities of a control plane (C-plane) and a user plane (U-plane), and may be used as MME (Mobility Management Entity) / UPE (User Plane Entity). The core network 400 includes a home location register (HLR) (not shown). The home location register, the identifier of the access gateway device that manages each mobile station apparatus 100 _n is held.

In the radio communication system according to the present embodiment, when access control is performed on each mobile station device 100 _n , the access control is equal (equal) between the mobile station devices 100 _n (users) of the same priority. Controlled.

  The access classes described above are classified for each priority (see, for example, Non-Patent Document 4). For example, general users, emergency calls, PLMN specific use users, security service users, public use users, emergency use users, and PLMN staff users are classified into seven types. For these seven types of access priorities, the ratio of time during which access control is performed (hereinafter referred to as access control ratio), the unit time subject to access control (hereinafter referred to as access control time unit), and access control A start timing (hereinafter referred to as access restriction start timing) is set. Hereinafter, the access restriction ratio, the access restriction time unit, and the access restriction start timing with respect to the access priority are referred to as access restriction setting information.

具体的には、例えば、表１に示すように、アクセスのプライオリティ毎に、アクセス規制割合が設定される。表１によれば、アクセス規制割合は、０％−１００％において、１０％毎に設定可能である。尚、表１は一例であり、適宜変更可能である。

Specifically, for example, as shown in Table 1, an access restriction ratio is set for each access priority. According to Table 1, the access control ratio can be set every 10% in 0% -100%. Table 1 is an example and can be changed as appropriate.

As shown in Table 2, the access restriction time unit can be set from 0 seconds to 1280 seconds, and the access restriction timing can be set from 0 SFN (system frame number) -4095 SFN. The SFN is a number notified from the network in order to synchronize between the network and the mobile station device 100 _n . In the UMTS system, the network repeatedly notifies a value from 0 to 4095. The unit is 10 msec. A similar method can be applied to the LTE system. Specifically, the access restriction time unit can be set to 0, 10, 20, 40, 80, 160, 320, 640, and 1280 seconds. Table 2 is an example and can be changed as appropriate.

The access restriction setting information for the access class is notified from the base station apparatus 200 to each mobile station apparatus 100 _n as broadcast information. As described above, the access restriction setting information includes the setting result of the access restriction ratio, the access restriction time unit, and the access restriction start timing.

When the mobile station device 100 _n receives the broadcast information, the mobile station device 100 _n performs access control in a certain time interval, that is, in the access control time unit, based on the access control ratio, the access control time unit, and the access control start timing included in the broadcast information. carry out.

  An access restriction operation in the wireless communication system according to the present embodiment will be described with reference to FIG.

  The wireless communication system according to the present embodiment includes a communication control device 500. The communication control device 500 may be included in the base station device 200 or may be included in the access gateway device 300 included in the core network 400. The core network 400 may be configured as a network device. In FIG. 2, the case where the communication control apparatus 500 is included in the base station apparatus 200 will be described.

  Communication control apparatus 500 transmits paging to all mobile station apparatuses located in the area covered by base station apparatus 200 (step S202). This paging includes notification information change notification.

The mobile station device 100 _n receives the broadcast information transmitted from the communication control device 500 (step S204). The mobile station device 100 _n starts access restriction at the access restriction start timing based on the access restriction setting information included in the broadcast information. Specifically, outgoing / incoming calls in the access restriction section in the access restriction time unit are restricted (step S206). The access restriction section in the access restriction time unit is determined by the access restriction time unit and the access restriction ratio included in the access restriction setting information.

  If the communication control device 500 determines to change the access restriction setting information, the communication control device 500 transmits paging including notification notification of change of broadcast information to all mobile station devices located in the area covered by the base station device 200 (step S208). ) And the mobile station device 100n receives the broadcast information again.

  The access restriction section in each mobile station apparatus corresponding to access classes 0-9 randomly assigned to general users is set in the mobile station apparatus in accordance with the access restriction ratio so as to be equal (equal) in each access class. Is done. As an example, FIG. 3 shows a case where the access restriction ratio is 10%.

Conventionally, in order to uniformly restrict access to general users, it is necessary to set and restrict access for each access class for each access class. In this embodiment, as compared with the method of this conventional access restriction, the mobile station apparatus 100 _n, based on the access class and access control setting information, it is possible to calculate the access control section, the paging for the broadcast information change The number of times can be reduced, and equal access restrictions can be implemented for general users. For example, the restriction section can be set with an access restriction ratio.

  Next, a communication control apparatus 500 according to an embodiment of the present invention will be described with reference to FIG.

  The communication control apparatus 500 according to the present embodiment includes a congestion detection unit 502, a restriction processing unit 504 as an access restriction determination unit and a notification information generation unit, and a transmission unit 506.

  The congestion detection unit 502 receives a congestion report from the wireless side or the core network 400 side, detects the congestion, and inputs the congestion state information to the restriction processing unit 504.

  The restriction processing unit 504 determines an access restriction ratio (restriction rate) based on restriction state information input from the congestion detection unit 502, for example, using a predetermined algorithm. For example, the restriction processing unit 504 determines the access restriction ratio described with reference to Table 1 based on the congestion state. In addition, the restriction processing unit 504 determines an access restriction time unit and an access restriction start timing using, for example, a predetermined algorithm. The restriction processing unit 504 inputs the determined access restriction ratio, access restriction time unit, and access restriction start timing to the transmission unit 506 as access restriction setting information. For example, the restriction processing unit 504 determines the access restriction ratio described with reference to Table 1 based on the congestion state.

  The transmission unit 506 broadcasts the input access restriction setting information. As a result, it is received by the mobile station apparatus 100 located in the area covered by the base station apparatus 200 including the own communication control apparatus 500.

Next, the mobile station apparatus 100 _n according to this embodiment is described with reference to FIG.

The mobile station apparatus 100 _{n according} to the present embodiment includes a receiving unit 102, a restriction processing unit 104 as an access restriction processing unit, an outgoing / incoming detection unit 106 as an access class detection unit, and a transmission unit 108.

  The receiving unit 102 receives the broadcast information transmitted from the base station apparatus 200 and inputs access restriction setting information included in the broadcast information to the restriction processing unit 104.

  The restriction processing unit 104 performs access restriction processing according to the access restriction setting information based on the access restriction setting information input by the receiving unit 102.

  The outgoing / incoming detection unit 106 detects outgoing operations and incoming calls, and triggers the detection to inquire the current access restriction status from the restriction processing unit 104, and performs outgoing / incoming processing according to the current access restriction status. For example, when the access is not restricted, the outgoing / incoming call is continued, and when the access is restricted, the outgoing / incoming call is stopped.

  According to the present embodiment, the access classes in the network are classified for each priority, and the access restriction ratio is set at a rate of 0% to 100% for each priority. User access restrictions are set to be equal. By doing in this way, it is possible to implement equal access regulation.

  Further, by making it possible to set the access restriction time unit, the access restriction section can be calculated based on the access class and the access restriction setting information, and the number of times of paging for changing the broadcast information can be reduced.

  In the present embodiment, the case where the restriction start timing is included in the access restriction setting information and notified by the broadcast information has been described, but may be set in advance according to specifications.

  In addition, for general users, an algorithm for equalizing access restrictions may be set to be equal in the network, or may be set in advance according to specifications.

  Next, a radio communication system according to another embodiment of the present invention will be described.

  The configurations of the radio communication system, the communication control apparatus, and the mobile station apparatus according to the present embodiment are the same as those described with reference to FIGS.

  In the wireless communication system according to the present embodiment, the communication control apparatus may transmit the broadcast information with the re-reception cycle information of the broadcast information. Further, the type of notification information to be acquired may be transmitted. When the content of the access restriction setting information is changed, the communication control apparatus 500 transmits the changed access restriction setting information, and the mobile station apparatus obtains the received broadcast information re-reception period and in addition thereto. The broadcast information is re-received based on the type of broadcast information. By doing so, it is possible to efficiently use radio resources and implement notification change of broadcast information.

For example, the communication control unit 500 notifies the re-reception period to receive the broadcast information to the mobile station apparatus 100 _n. The mobile station device 100 _n performs broadcast information reception processing based on the re-reception cycle transmitted from the communication control device 500. For example, when the broadcast information is periodically changed, the re-reception period may be set in units of the change period.

例えば、表３に示すように、再受信周期としては、０ ＳＦＮ−４０９５ ＳＦＮで設定され、このとき取得可能な報知情報としては、ＳＩＢ １−ＳＩＢ １８が指定される。

For example, as shown in Table 3, the re-reception period is set to 0 SFN-4095 SFN, and SIB 1-SIB 18 is designated as broadcast information that can be acquired at this time.

  When the communication control device 500 needs to change the access restriction setting information in a short period of time, for example, when it is necessary to change the access restriction ratio in a short period of time, broadcast information including a short-term re-reception cycle is provided. Sent.

The mobile station device 100 _n re-receives the broadcast information at regular intervals designated by the broadcast information re-reception cycle, and performs the operation designated there.

Conventionally, every time the content of the notification information is changed, notification must be made by paging. According to this embodiment, the communication control unit 500 transmits a re-reception cycle of the broadcast information to the mobile station apparatus 100 _n, the mobile station apparatus 100 _n is by receiving the broadcast information periodically in accordance該再reception period, The number of paging transmissions can be reduced. As a result, it is possible to reduce waste of radio resources, and it is not necessary to perform unnecessary processing on the network side, and broadcast information can be easily changed.

  Furthermore, when a re-reception cycle is set, it is possible to receive only specific information by explicitly indicating broadcast information to be acquired, and to shorten broadcast information reception time. This can also be used for purposes other than access control. For example, a case where a change in channel information, a change in network configuration, a base station reset, or the like occurs.

  Next, the communication control apparatus 500 according to the embodiment of the present invention will be described.

  A transmission unit 506 serving as a re-reception period generation unit generates a re-reception period for receiving broadcast information, and transmits the broadcast information including the re-reception period. In this case, the transmission unit 506 transmits the broadcast information according to the set re-reception cycle.

Next, the mobile station apparatus 100 _{n according} to the present embodiment is described.

  When the re-reception cycle is notified by the communication control device 500, the reception unit 102 performs reception processing according to the re-reception cycle.

  Next, processing of the communication control apparatus 500 according to the present embodiment will be described.

  First, a method for calculating an access restriction section in an access class will be described with reference to FIG. The method for calculating the access restriction section described here can also be applied to the above-described embodiment.

The restriction processing unit 104 of the mobile station apparatus 100 _n belonging to each access class 0-9 performs access restriction from the restriction start position for each access class to the restriction end position for each access class in an access restriction time unit. Here, the restriction start position for each access class is determined by the access restriction start timing, and the restriction end position for each access class is determined by the access restriction ratio from the restriction start position for each access class. The access restriction start timing, the access restriction time unit, and the access restriction ratio are instructed by the broadcast information.

  For example, the restriction start position for each access class is calculated by the following expressions (1) and (2). The start and end will be described in units of SFN.

Restriction start position (SFN) for each access class = access restriction start timing + access class × access restriction time unit / (number of access classes with the same priority) × SFN unit (1)
Restriction end position for each access class (SFN) = Regulation start position for each access class + Access restriction time unit × SFN unit × Access restriction ratio (2)
However, if the restriction end position for each access class> the access restriction start timing + the access restriction time unit × the SFN unit, the restriction section is also defined between the restriction start position 2 for each access class and the restriction end position 2 for each access class. Here, the restriction start position 2 for each access class is the access class restriction start timing, and the restriction end position 2 for each access class is equal to the access class restriction start timing + access class restriction time unit × SFN unit × restriction rate− (access class (Restriction start timing + access class restriction time unit × SFN unit−restriction start position for each access class).

  As an example, a case will be described in which the access restriction start timing is 0, the access restriction time unit is 20 seconds, the access restriction ratio is 90%, the access class is 0, and the number of access classes having the same priority is 10.

  In this case, it is calculated as follows.

Restriction start position for each access class = 0 + 0 × 20 ÷ 10 × 100 = 0
Restriction end position for each access class = 0 + 20 × 100 × 0.9 = 1800
The restriction end position for each access class is 1800, access restriction start timing + access restriction time unit × SFN unit is 2000, and restriction end position for each access class <access restriction start timing + access restriction time unit × SFN unit. It is not necessary to set the restriction section between the restriction start position 2 for each access class and the restriction end position 2 for each access class.

  As another example, a case where the access restriction start timing is 0, the access restriction time unit is 20 seconds, the access restriction ratio is 90%, and the access class is 8 will be described.

Restriction start position for each access class = 0 + 8 × 20 ÷ 10 × 100 = 1600
Restriction end position for each access class = 1600 + 20 × 100 × 0.9 = 3400
The restriction end position for each access class is 3400, access restriction start timing + access restriction time unit × SFN unit is 1800, and restriction end position for each access class> access restriction start timing + access restriction time unit × SFN unit. It is necessary to set a restriction section between the restriction start position 2 for each access class and the restriction end position 2 for each access class.

  Since the restriction start position 2 for each access class is 0, and the restriction end position 2 for each access class is 0 + 20 × 100 × 0.9− (0 + 20 × 100-1600) = 1400, access restriction start timing 0 (SFN) Between 1400 (SFN) also needs to be set as a regulation section.

  Next, an access control method according to the present embodiment will be described.

  In the present embodiment, as an example, a case where network traffic increases and access restriction is performed will be described.

  Specifically, the following access restrictions are performed.

  (1) Access restriction ratio for general users, ie, mobile station apparatuses belonging to access class 0-9, is 90%, access restriction ratio for other users, ie, access classes 10-15, is 0%, and access restriction time unit is 20 seconds. Then, access restriction setting information (referred to here as access restriction setting information (1)) with a re-reception cycle of 2000 SFN and restriction start timing of 0 is set. After that, (2) the access restriction rate for general users, ie, mobile station devices belonging to access class 0-9, is 50%, the access restriction rate for other users, ie, access class 10-15, is 0%, and the access restriction time unit is The access restriction setting information is changed to 10 seconds, the re-reception cycle is 1000 SFN, and the restriction start timing is 0 (referred to here as access restriction setting information (2)). Thereafter, (3) access restriction is released. That is, the access restriction ratio for the general user, that is, the mobile station apparatus belonging to the access class 0-9 is 0%, the access restriction ratio for the other users, that is, the access class 10-15 is 0%, the access restriction time unit is 0 second, It is changed to access restriction setting information (referred to here as access restriction setting information (3)) in which the re-reception cycle is 0 SFN and the restriction start timing is 0. In this embodiment, the access restriction time unit is 0 for deregulation and the re-reception cycle is 0 for re-reception release. However, for example, Null information or the like may be set, and other values may be set as the release value. Good.

Here, the communication control apparatus 500 sets the access restriction start timing for the mobile station apparatus 100 _n by notifying the access restriction start timing by broadcast information. In addition, the mobile station device 100 _n is assumed to hold an algorithm for equalizing access restrictions for general users for each access class. For example, the mobile station device 100 _n holds the correspondence between the access restriction ratio and the access restriction section in each access class.

  In starting the access restriction, the restriction processing unit 504 of the communication control device 500 changes to notification information including the access restriction setting information (1) (step S702). The transmission unit 506 of the communication control device 500 notifies the changed notification information to all mobile station devices located in an area covered by the base station device 200 including the communication control device 500 by paging (step S704).

The mobile station device 100 _n receives the paging and the broadcast information (Step S706). The notification information may be changed manually by a network administrator, or may be automatically executed by batch processing when the access control threshold is exceeded in the communication control device 500. . When the communication control device 500 automatically sets, for example, the congestion detection unit 502 detects the access traffic, and when the access traffic exceeds a preset threshold, the congestion is detected. This is executed by notifying the restriction processing unit 504 that there is a certain event. This threshold is determined according to the traffic capacity allowed in the system.

The standby mobile station device 100 _{n that} has received the paging re-receives the broadcast information in accordance with the re-reception cycle 2000 SFN included in the broadcast information (step S708). For example, the communication control apparatus 500 may transmit broadcast information including the changed access restriction setting information only when the access restriction setting information is changed according to the re-reception cycle.

The restriction processing unit 104 of the mobile station device 100 _n performs access restriction according to the access restriction setting information included in the broadcast information. Specifically, regulation processing unit 104, the self when the mobile station apparatus 100 _n is a mobile station apparatus 100 _n of the general users with access classes 0, the restriction time of 18 seconds SFN0 (access restriction time units 20 seconds × 90%), and when the own mobile station device 100 _n is a mobile station device 100 _n of a general user having access class 1, the restriction time is restricted from SFN 200 for 18 seconds. Hereinafter, when the own mobile station device 100 _n is the mobile station device 100 _n of a general user having the access class 2-9, the access restriction is executed by performing the same calculation as that described above. That is, the regulation start timing (SFN) of each mobile station can be expressed as follows, similarly to the above-described equations (1) and (2).

Access restriction start position of each mobile station device = restriction start timing + access class × access restriction time unit ÷ 10 × SFN unit Restriction end position for each access class = restriction start position for each access class + access restriction time unit × SFN unit × However, if the restriction end position for each access class> the access restriction start timing + the access restriction time unit × the SFN unit, the restriction interval is also between the restriction start position 2 for each access class and the restriction end position 2 for each access class. And Here, the restriction start position 2 for each access class is the access class restriction start timing, and the restriction end position 2 for each access class is equal to the access class restriction start timing + access class restriction time unit × SFN unit × restriction rate− (access class (Restriction start timing + access class restriction time unit × SFN unit−restriction start position for each access class).

The restriction processing unit 504 of the communication control device 500 changes the access restriction setting information (1) to the access restriction setting information (2), and transmits notification information including the changed access restriction setting information (2) (step). S710). The transmission unit 506 of the communication control apparatus 500 notifies the changed notification information to all mobile station apparatuses located in an area covered by the base station apparatus 200 including the communication control apparatus 500 according to the re-reception cycle. Since the mobile station device 100 _n performs reception processing according to the re-reception cycle, there is no need for paging.

The mobile station device 100 _n receives the broadcast information including the changed access restriction setting information (2) (step S712). The restriction processing unit 104 of the mobile station device 100 _n performs access restriction according to the access restriction setting information (2) included in the broadcast information. Specifically, regulation processing unit 104, when the mobile station apparatus 100 _n is a mobile station apparatus 100 _n of the general users with access classes 0, the restriction time of 5 seconds SFN0 (access restriction time units (10 seconds × 50%), and when the own mobile station device 100 _n is a mobile station device 100 _n of a general user having an access class 1, the restriction time is restricted from the SFN 100 for 5 seconds. Hereinafter, when the own mobile station device 100 _n is the mobile station device 100 _n of a general user having the access class 2-9, the access restriction is executed by performing the same calculation as that described above.

Mobile station apparatus 100 _n includes each period specified by the communication control device 500, that is, re-reception cycle (particular) receives the broadcast information (step S714), and switching of the access control operation each time, it sets Perform the operation.

When access control is no longer necessary, the communication control device 500 has no access control, that is, the access control setting information (2) is changed to the access control setting information (3), and the changed access control setting information (3) is changed. The broadcast information including it is transmitted (step S716). The transmission unit 506 of the communication control apparatus 500 notifies the changed notification information to all mobile station apparatuses located in an area covered by the base station apparatus 200 including the communication control apparatus 500 according to the re-reception cycle. Since the mobile station device 100 _n performs reception processing according to the re-reception cycle, there is no need for paging. In the access restriction setting information (3), information on which access restriction is not performed is specifically shown. However, when notifying that access restriction is not performed, notification information including that access restriction is released May be notified.

The mobile station device 100 _n receives the broadcast information including the changed access restriction setting information (3) (step S718). Regulation processing unit 104 of the mobile station apparatus 100 _n performs the release of access restriction according to the access restriction setting information included in the broadcast information (3). Specifically, the restriction processing unit 104 changes, that is, updates the access restriction information, and releases the restriction after waiting for the next access restriction start timing, for example, SFN 0. If the re-reception cycle comes before the next access restriction start timing comes, the mobile station device 100 _n performs broadcast information reception processing. In the access restriction information (3), the re-reception cycle is set to 0, so that the normal standby state is restored and no re-reception is performed.

  Next, access restriction processing in the communication control apparatus 500 according to the present embodiment will be described with reference to FIG.

  The congestion detection unit 502 receives the congestion report from the wireless side or the core network 400 side, determines the congestion, and inputs the congestion state information to the restriction processing unit 504 (step S802).

  The restriction processing unit 504 determines an access restriction ratio (restriction rate) based on the congestion state information input from the congestion detection unit 502. Further, the restriction processing unit 504 determines an access restriction time unit and an access restriction start timing. The restriction processing unit 504 inputs the determined access restriction ratio, access restriction time unit, and access restriction start timing to the transmission unit 506 as access restriction setting information (step S804).

  The transmission unit 506 changes to broadcast information including the input access restriction setting information (step S806).

  Transmitting section 506 transmits the changed notification information and paging to mobile station apparatus 100 located in the area covered by base station apparatus 200 including own communication control apparatus 500 (step S808).

  The restriction processing unit 504 determines an access restriction ratio (restriction rate) based on restriction state information input from the congestion detection unit 502, and further determines an access restriction time unit and an access restriction start timing.

  Based on the determined access restriction ratio, the transmission unit 506 changes the broadcast information (step S810).

Next, the reception processing of the access restriction setting information in the mobile station apparatus 100 _n according to this embodiment will be described with reference to FIG.

  The receiving unit 102 receives the paging transmitted by the communication control device 500 (step S902).

  The receiving unit 102 determines whether or not notification information change notification is included in the paging (step S904). When the notification information change notification is not included (step S904: NO), an incoming call procedure is performed (step S906).

  On the other hand, when notification information change notification is included (step S904: YES), the receiving unit 102 receives the notification information (step S908).

  The restriction processing unit 104 checks restriction information (step S910). Note that the restriction information here does not include the broadcast information re-reception cycle.

  When there is a change in the restriction information, a restriction rate process described later is performed (step S912).

  On the other hand, when there is no change in the restriction information and after the restriction rate process, the receiving unit 102 determines whether or not the re-reception cycle is 0 (step S914). For example, the receiving unit 102 inquires of the restriction processing unit 104 about the re-reception period, and determines whether or not the re-reception period is zero.

  If the re-reception cycle is 0 (step S914: YES), the process ends.

  On the other hand, when the re-reception cycle is not 0 (step S914: NO), the receiving unit 102 sets a broadcast information re-reception timer (step S916).

  The receiving unit 102 determines whether the broadcast information re-reception timing has come (step S918).

  When it is the broadcast information re-reception timing (step S918: YES), the process returns to step S908.

  On the other hand, when the notification information re-reception timing is not reached (step S918: NO), the process returns to step S918.

Next, restriction rate processing in the mobile station apparatus 100 _{n according} to the present embodiment will be described with reference to FIG.

  The restriction processing unit 104 checks the access class and priority stored in the USIM (step S1002). Table 4 shows the access classes held in the USIM.

規制処理部１０４は、報知情報に含まれるアクセス規制設定情報から、自移動局装置１００_ｎが規制対象であるか否かを判断する（ステップＳ１００４）。例えば、自移動局装置１００_ｎのアクセスクラスが規制対象のプライオリティに含まれるアクセスクラスであるか否かを判断する。報知情報には、他のアクセスクラスやプライオリティに対するアクセス規制設定情報も含まれる。

The restriction processing unit 104 determines from the access restriction setting information included in the broadcast information whether or not the own mobile station device _100n is a restriction target (step S1004). For example, it is determined whether or not the access class of the own mobile station apparatus 100 _{n is} an access class included in the priority to be regulated. The broadcast information includes access restriction setting information for other access classes and priorities.

When the own mobile station device 100 _n is a restriction target (step S1004: YES), the restriction processing unit 104 checks the number of access classes having the same priority.

  The restriction processing unit 104 acquires restriction information (step S1008). Specifically, the restriction processing unit 104 calculates the restriction start timing and the restriction period of the mobile station apparatus. For example, the restriction start timing and the access restriction time are calculated by the above formulas (1) and (2).

Next, the access control process in the mobile station apparatus 100 _n according to this embodiment is described with reference to FIG. 11. Here, a case where the user performs a transmission operation on the mobile station device 100 _n will be described.

  The outgoing / incoming detection unit 106 detects outgoing (step S1102).

  The outgoing / incoming detection unit 106 confirms outgoing information (step S1104).

  The outgoing / incoming detection unit 106 determines whether or not to change the access class (step S1106). For example, the outgoing / incoming detection unit 106 changes the access class to 10 when the destination is an emergency call. For example, the outgoing / incoming call detection unit 106 maintains an emergency call number table as shown in Table 5, refers to the emergency call number table, compares which of the emergency number table the outgoing call information corresponds to, and applies Change the access class to 10.

  Although the case of an emergency call has been described here, a call number table indicating a call number when an access class is changed to other than a general user is maintained for other than an emergency call, and compared with the call number table. Thus, it may be determined whether to change the access class.

  When the access class is changed (step S1106: YES), the outgoing / incoming detection unit 106 requests the restriction processing unit 104 to recalculate the restriction rate process, and the restriction processing unit 104 recalculates the restriction rate process. (Step S1108). In this case, the access class is only temporarily changed, and the original access class is held in the USIM.

  On the other hand, when the access class is not changed (step S1106: NO) and when the restriction rate process is recalculated, the outgoing / incoming call detection unit 106 inquires the restriction processing unit 104 about the restriction period (step S1110). The restriction period is calculated at the time when the notification information is received, and the result is held. When there is an incoming / outgoing call, recalculation is performed as described above.

  The outgoing / incoming detection unit 106 determines whether or not it is the restriction period based on the inquiry about the restriction period (step S1112).

  When it is a regulation period (step S1112: YES), the outgoing / incoming call detection unit 106 disables outgoing calls (step S1114).

  On the other hand, when it is not the regulation period (step S1112: NO), the outgoing / incoming call detection unit 106 performs outgoing call (step S1116).

Next, the access control process in the mobile station apparatus 100 _n according to this embodiment is described with reference to FIG. 12. Here, a case where there is an incoming call to mobile station apparatus 100 _n will be described.

  The incoming / outgoing call detection unit 106 detects an incoming call (step S1202).

  The incoming / outgoing call detection unit 106 confirms incoming call information (step S1204).

  The outgoing / incoming detection unit 106 determines whether or not to change the access class (step S1206). For example, the outgoing / incoming detection unit 106 changes the access class to 10 when the call is an emergency call. Whether or not the emergency call is successful may be confirmed from the telephone number of the caller, the flag indicating the emergency call may be included in the incoming information, or the access class 10 may be specified in the incoming information. In the case of confirmation from the telephone number of the caller, the mobile station apparatus holds a telephone number table indicating the telephone number of the emergency call, and the determination is made based on the telephone number table of the emergency call. Similarly, in cases other than emergency calls, the type of call may be determined from the incoming call information to determine whether or not the access class needs to be changed.

  Although the case of an emergency call has been described here, a call number table is maintained and the access class is changed by comparing with the call number table when the access class is changed to a non-general user other than an emergency call. Whether or not to do so may be determined.

  When the access class is changed (step S1206: YES), the outgoing / incoming detection unit 106 requests the restriction processing unit 104 to recalculate the restriction rate process, and the restriction processing unit 104 recalculates the restriction rate process. (Step S1208). In this case, the access class is only temporarily changed, and the original access class is held in the USIM.

  On the other hand, when the access class is not changed (step S1206: NO) and when the restriction rate processing is recalculated, the outgoing / incoming detection unit 106 inquires the restriction processing unit 104 about the restriction period (step S1210). The restriction period is calculated when the notification information is received, and the result is stored. When there is an incoming / outgoing call, an inquiry is made as to whether the current period is the corresponding period. However, if the access class is changed, recalculation is required.

  The outgoing / incoming detection unit 106 determines whether or not it is the restriction period based on the inquiry about the restriction period (step S1212).

  When it is a regulation period (step S1212: YES), the incoming / outgoing call detection unit 106 disables incoming calls (step S1214).

  On the other hand, when it is not the regulation period (step S1212: NO), the outgoing / incoming detection unit 106 performs incoming (step S1216).

  According to the present embodiment, the communication control apparatus can set the period for re-receiving the broadcast information and can notify the set period for re-receiving. This notification information is set, for example, in units of notification information.

  In addition, notification information that needs to be reacquired can be set.

  Further, in this embodiment, an example in which the access classes 0-9 are assigned to the general user priority has been described, but the same can be applied to a case where a plurality of access classes have other priorities.

  Next, a radio communication system according to another embodiment of the present invention will be described.

  The configurations of the wireless communication system, the network device, and the mobile station device according to the present embodiment are the same as those described with reference to FIGS.

  The wireless communication system according to the present embodiment differs from the above-described embodiment in access restriction processing.

The access regulation processing in the mobile station apparatus 100 _n according to this embodiment is described with reference to FIG. 13. Here, a case where the user performs a transmission operation on the mobile station device 100 _n will be described.

  The outgoing / incoming detection unit 106 detects outgoing (step S1302).

  The outgoing / incoming detection unit 106 confirms the outgoing information (step S1304). For example, the outgoing / incoming detection unit 106 changes the access class to 10 when the destination is an emergency call. For example, the outgoing / incoming call detection unit 106 maintains an emergency call number table as shown in Table 5, refers to the emergency call number table, compares which of the emergency number table the outgoing call information corresponds to, and applies Change the access class to 10.

この場合、アクセスクラスは一時的に変更されるだけで、本来のアクセスクラスは、ＵＳＩＭに保持される。アクセスクラスの変更が行われた場合には、該変更されたアクセスクラスが優先される。アクセスクラスの変更が行われない場合には、本来のアクセスクラスが使用される。ここでは、緊急呼の場合について説明したが、緊急呼以外でも、アクセスクラスが一般ユーザ以外に変更になる場合に発信番号表を保持し、該発信番号表と比較することにより、アクセスクラスを変更するか否かを判断するようにしてもよい。

In this case, the access class is only temporarily changed, and the original access class is held in the USIM. When the access class is changed, the changed access class is given priority. When the access class is not changed, the original access class is used. Although the case of an emergency call has been described here, a call number table is maintained and the access class is changed by comparing with the call number table when the access class is changed to a non-general user other than an emergency call. Whether or not to do so may be determined.

  For example, as shown in Table 6, a call number table in which the access class is changed to 11 may be held.

発着信検出部１０６は、アクセスクラスを取得する（ステップＳ１３０６）。

The outgoing / incoming call detection unit 106 acquires an access class (step S1306).

  The outgoing / incoming call detection unit 106 makes an inquiry about the restriction section to the restriction processing unit 104 (step S1308). For example, the outgoing / incoming call detection unit 106 inputs the acquired access class to the restriction processing unit 104 and inquires about the restricted section of the access class. Here, the restriction processing unit 104 calculates the restriction rate based on the input access class, and determines whether or not the present time corresponds to the restriction section. The restriction processing unit 104 inputs a determination result as to whether or not the current time corresponds to the restriction section to the outgoing / incoming call detection unit 106.

  The outgoing / incoming detection unit 106 determines whether or not the current time is the restriction period based on the determination result of whether or not the current input by the restriction processing unit 104 corresponds to the restriction section (step S1310).

  When it is a regulation period (step S1310: YES), the outgoing / incoming call detection unit 106 disables outgoing calls (step S1312).

  On the other hand, when it is not the regulation period (step S1310: NO), the outgoing / incoming detection unit 106 performs outgoing (step S1314).

Next, the access control process in the mobile station apparatus 100 _n according to the present embodiment will be described with reference to FIG. 14.

  The incoming / outgoing call detection unit 106 detects an incoming call (step S1402).

The outgoing / incoming call detection unit 106 confirms incoming call information (step S1404). For example, in the case of an emergency call, the access class detector 106 changes the access class to 10. Whether or not the emergency call is successful may be confirmed from the telephone number of the caller, the flag indicating the emergency call may be included in the incoming information, or the access class 10 may be specified in the incoming information. In the case of confirmation from the telephone number of the caller, the mobile station apparatus _100n holds the emergency call telephone number table, and the determination is made based on the emergency call telephone number table. Similarly, in cases other than emergency calls, the type of call may be determined from the incoming call information to determine whether or not the access class needs to be changed. Although the case of an emergency call has been described here, a call number table is maintained and the access class is changed by comparing with the call number table when the access class is changed to a non-general user other than an emergency call. Whether or not to do so may be determined. For example, as shown in Table 6, a calling number table in which the access class is changed to 11 may be held.

  The outgoing / incoming detection unit 106 acquires an access class (step S1406).

  The outgoing / incoming detection unit 106 makes an inquiry about the restriction section to the restriction processing unit 104 (step S1408). For example, the outgoing / incoming call detection unit 106 inputs the acquired access class to the restriction processing unit 104 and inquires about the restricted section of the access class. Here, the restriction processing unit 104 calculates the restriction rate based on the input access class, and determines whether or not the present time corresponds to the restriction section. The restriction processing unit 104 inputs a determination result as to whether or not the current time corresponds to the restriction section to the outgoing / incoming call detection unit 106.

  The outgoing / incoming call detection unit 106 determines whether or not the current time is the restriction period based on the determination result of whether or not the current input by the restriction processing unit 104 corresponds to the restriction section (step S1410).

  When it is a regulation period (step S1410: YES), the outgoing / incoming call detection unit 106 disables incoming calls (step S1412).

  On the other hand, when it is not the regulation period (step S1410: NO), the outgoing / incoming call detection unit 106 performs incoming call (step S1414).

  In the embodiment described above, the case where the number of access classes is fixed by USIM has been described, but the number of access classes may also be notified by broadcast information.

  In addition, the access restriction has been described. However, in the case other than the access restriction, for example, when the channel information is changed, the network configuration is changed, the base station apparatus is reset, the same configuration can be applied.

  Moreover, although the case where the access restriction setting information is general user a% and other b% has been described, general user a%, emergency call b%, PLMN specific user c%, security service user d%, public user e%, emergency use user f%, PLMN staff user g% and all priorities may be notified, or only priority with restriction information may be notified.

  According to the embodiment of the present invention, when access restriction is applied, the restriction can be made uniform among users having the same priority.

  Further, the number of paging due to access restrictions can be reduced.

  Also, when broadcast information is transmitted in a short time, the network can notify the mobile station device that the broadcast information has been changed without paging.

  In the embodiment, the case where there is broadcast information re-reception period information is described, but paging may be transmitted every time when there is no such information and access restriction occurs or restriction information is changed. In that case, the processing flow of the mobile station apparatus is the flow of FIG. 9, and after the restriction information confirmation (step S910), if there is a change, the process proceeds to the restriction rate process (step S912), and ends if there is no change. It is not necessary to determine whether or not the broadcast information re-reception cycle is 0 (step S914), the broadcast information re-reception timer set (step S916), and the broadcast information re-reception timing (step S918).

  In the embodiment, a case has been described in which the broadcast information to be changed is access restriction restriction information. However, these may be channel information change, not restriction information. Or the aspect which detects only the change of a broadcast information re-reception period, and sets a broadcast information re-reception timer may be sufficient. In this case, the processing flow of the mobile station apparatus is the flow of FIG. 9 and is a step of confirming the broadcast information re-reception cycle instead of the restriction information confirmation (step S910), and the broadcast information re-reception cycle is 0 regardless of whether there is a change or not. Is determined (step S914), and broadcast information re-reception timer set (step S916) is performed. A process corresponding to the restriction rate process (step S912) is not required.

  In the above-described embodiment, an example of a system to which Evolved UTRA and UTRAN (also known as Long Term Evolution or Super 3G) is applied has been described. However, the communication control device, mobile station device, and mobile device according to the present invention have been described.
