Abstract: To abolish grouping and realize a regulation of the whole terminal at a high accuracy in accordance with an optional regulation rate. A communication regulation state change instruction is output from the timer generator means 23 at a cycle corresponding to the regulation unit time communicated from a radio base-station apparatus 1 to a radio communication terminal unit 2. When the communication regulation state change instruction is output, a communication regulation state is determined in accordance with a result of comparison of the random number generated by the random-number generating means 25 with a predetermined regulation rate. A communication of the radio communication terminal unit is regulated in accordance with the determination. Thus, it is possible to autonomously determine whether the present state is a regulation state in accordance with the clock value of a timer by the terminal unit and change operation states.

Abstract: A user guidance system includes a communication history receiver receiving communication history information of a mobile communication terminal; a traffic information generator receiving resource state information from a base station and generating communication traffic information at the base station; a dissatisfaction calculator calculating a dissatisfaction with a recommended action to a user of the mobile communication terminal, based on the communication history information and the communication traffic information; a recommended action extractor extracting a recommended action for the user to be notified of, based on dissatisfactions with a plurality of recommended actions; and an information transmitter transmitting the recommended action to the mobile communication terminal.

Abstract: In a communication system a plurality of user terminals located in a plurality of service areas perform communications. The communication system includes a mobility control node configured to manage a service area where each user terminal is located; a session control node configured to manage a communication history of a communication performed by each user terminal; and a network load prediction node configured to acquire user information of the user terminal located in each service area and the communication history of each user terminal at predetermined timing, and to calculate a communication demand prediction in each service area based on the user information and the communication history.

Abstract: A priority control system 10 is comprised of a priority control server 12, a base station 14, and a terminal 16. The priority control server 12 is provided with a priority issue history storage 18, a priority control determiner 20, a scheduler 22, and a priority transmitter 24. The priority control determiner 20 receives a connection request containing a priority from the base station 14 and determines whether a priority is to be issued for the terminal 16, and whether priority control is to be carried out. The scheduler 22 determines a priority control time slot for priority control on the basis of a request from the priority control determiner 20. The priority transmitter 24 transmits the priority. A restriction controller 28 of the base station 14 performs the priority control at a restriction rate lower than usual, based on a request from the priority control determiner 20. This reduces loads on the communication system and decreases the number of call requests.
