Restriction control apparatus, restriction control system, and restriction control method

Abstract

A restriction control apparatus configured to perform restriction control of communication of a user apparatus in a mobile communication system includes an information obtaining unit configured to obtain, from a user information management apparatus in the mobile communication system, group identification information indicating a group to which the user apparatus belongs, and a restriction determination unit configured, when receiving a communication request from the user apparatus, to determine whether the group to which the user apparatus belongs is a control target or not based on the group identification information and group identification information of a control target determined by the restriction control apparatus.

1 . A restriction control apparatus configured to perform restriction control of communication of a user apparatus in a mobile communication system, comprising:
 an information obtaining unit configured to obtain, from a user information management apparatus in the mobile communication system, group identification information indicating a group to which the user apparatus belongs; and   a restriction determination unit configured, when receiving a communication request from the user apparatus, to determine whether the group to which the user apparatus belongs is a control target or not based on the group identification information and group identification information of a control target determined by the restriction control apparatus.   
     
     
         2 . The restriction control apparatus as claimed in  claim 1 , comprising a communication request processing unit configured, when the group to which the user apparatus belongs is determined to be a control target by the restriction determination unit, to reject the communication request or to perform restriction control according to a predetermined rule. 
     
     
         3 . The restriction control apparatus as claimed in  claim 1 , wherein the restriction control apparatus includes a user information storage unit configured to store group identification information and user identification information by associating them with each other, and
 wherein the restriction determination unit obtains the group identification information from the user information storage unit based on user identification information included in the communication request, and determines whether the group to which the user apparatus belongs is a control target or not based on the group identification information and group identification information of a control target determined by the restriction control apparatus.   
     
     
         4 . A restriction control system including the restriction control apparatus as claimed in  claim 1  and a radio access control apparatus in the mobile communication system,
 the radio access control apparatus comprising: 
 a determination unit configured, when receiving a connection request including group identification information from a user apparatus, to determine whether a group to which the user apparatus belongs is a control target or not based on the group identification information and a group identification information of a control target designated from the operation system. 
 
     
     
         5 . A restriction control method in a mobile communication system that includes a restriction control apparatus configured to perform restriction control of communication of a user apparatus, and includes a user information management apparatus, wherein
 the user information management apparatus holds group identification information indicating a group to which a user apparatus belongs for each user apparatus,   the restriction control apparatus obtains group identification information from the user information management apparatus, and   when the restriction control apparatus receives a communication request from the user apparatus, the restriction control apparatus determines whether the group to which the user apparatus of a transmission source of the communication request belongs is a control target or not based on the group identification information of the user apparatus obtained from the user information management apparatus and group identification information of a control target determined by the restriction control apparatus.   
     
     
         6 . The restriction control method as claimed in  claim 5 , wherein, when the restriction control apparatus determines that the group to which the user apparatus of a transmission source of the communication request belongs is a control target, the restriction control apparatus rejects the communication request or performs restriction control according to a predetermined rule. 
     
     
         7 . The restriction control apparatus as claimed in  claim 2 , wherein the restriction control apparatus includes a user information storage unit configured to store group identification information and user identification information by associating them with each other, and
 wherein the restriction determination unit obtains the group identification information from the user information storage unit based on user identification information included in the communication request, and determines whether the group to which the user apparatus belongs is a control target or not based on the group identification information and group identification information of a control target determined by the restriction control apparatus.   
     
     
         8 . A restriction control system including the restriction control apparatus as claimed in  claim 2  and a radio access control apparatus in the mobile communication system,
 the radio access control apparatus comprising: 
 a determination unit configured, when receiving a connection request including group identification information from a user apparatus, to determine whether a group to which the user apparatus belongs is a control target or not based on the group identification information and a group identification information of a control target designated from the operation system. 
 
     
     
         9 . A restriction control system including the restriction control apparatus as claimed in  claim 3  and a radio access control apparatus in the mobile communication system,
 the radio access control apparatus comprising: 
 a determination unit configured, when receiving a connection request including group identification information from a user apparatus, to determine whether a group to which the user apparatus belongs is a control target or not based on the group identification information and a group identification information of a control target designated from the operation system.
