FIG. 6 is a flowchart illustrating processing in which the wireless communication terminal 10 transmits a registration deletion request to the registration management device 40 based on the remaining capacity value of the battery 19.
First, the terminal state detection circuit 12 of the wireless communication terminal 10 detects the remaining capacity value of the battery 19 at regular intervals (step Sa1). Next, the terminal registration deletion determination circuit 13 receives the remaining capacity value from the terminal state detection circuit 12 and reads the remaining battery capacity threshold value stored in the usage information storage circuit 14. Then, the remaining capacity value is compared with the battery remaining capacity threshold value, and it is determined whether or not the remaining capacity value is equal to or less than the battery remaining capacity threshold value (step Sa2).

  If the remaining capacity value is not less than or equal to the battery remaining capacity threshold value, the process returns to step Sa1. On the other hand, when the remaining capacity value is equal to or less than the battery remaining capacity threshold, the terminal registration deletion determination circuit 13 reads out the wireless communication terminal identification information from the usage information storage circuit 14, and the registration deletion including the read out wireless communication terminal identification information Instruction information is transmitted to the wireless data processing circuit 16 so as to transmit the request. The wireless data processing circuit 16 causes the wireless transmission / reception circuit 18 to transmit a wireless signal including a registration deletion request to the wireless base station 30 via the antenna 22 via the wireless interface circuit 17 (step Sa4). Then, the terminal registration deletion determination circuit 13 deletes the information stored in the usage information storage circuit 14 (step Sa5).

It can be deleted without any administrator action.

The terminal registration deletion determination circuit 13 determines the condition that the remaining capacity value is equal to or less than the battery remaining capacity threshold, but the remaining capacity value is not limited to the condition that the remaining capacity value is equal to or less than the battery remaining capacity threshold. The condition may be that the battery remaining capacity is less than the threshold.
Further, when the terminal state detection circuit 12 detects the remaining capacity value, the terminal registration deletion determination circuit 13 does not make a determination, but records the remaining capacity value detected by the terminal state detection circuit 12 in the terminal state storage circuit 11. The terminal registration deletion determination circuit 13 may perform determination at an interval different from the interval detected by the terminal state detection circuit 12.

  FIG. 7 is a flowchart showing registration deletion processing of the registration management apparatus 40 that has received the registration deletion request. The network interface circuit 41 of the registration management device 40 receives a registration deletion request from the wireless communication terminal 10 via the network 100 (step Sb1). The registration management circuit 43 reads the wireless communication terminal identification information from the registration deletion request received by the network interface circuit 41 (step Sb2). Then, the registration management circuit 43 deletes the registration information corresponding to the read wireless communication terminal identification information from the registration information storage circuit 42 (step Sb3).

FIG. 8 is a flowchart showing the registration deletion process of the wireless communication terminal 10 in which the expiration date is set in the usage information storage circuit 13 in advance.
First, the terminal registration deletion determination circuit 13 transmits an acquisition request to the clock 20 before starting wireless communication, for example, and receives date information as a response (step Sc1). Next, the terminal registration deletion determination circuit 13 reads the expiration date information set in advance from the usage information storage circuit 14. Then, the terminal registration deletion determination circuit 13 compares the date information received from the clock 20 with the expiration date information, and determines whether or not the date indicated by the date information exceeds the expiration date indicated by the expiration date information ( Step Sc2). If the date does not exceed the expiration date, the process returns to step Sc1. On the other hand, if the date exceeds the expiration date, the terminal registration deletion determination circuit 13 reads the wireless communication terminal identification information from the usage information storage circuit 14 and transmits a registration deletion request including the read wireless communication terminal identification information. Instruction information is transmitted to the wireless data processing circuit 16. The wireless data processing circuit 16 causes the wireless transmission / reception circuit 18 to transmit a wireless signal including a registration deletion request to the wireless base station 30 via the antenna 22 via the wireless interface circuit 17 (step Sc3). Then, the terminal registration deletion determination circuit 13 deletes the information stored in the usage information storage circuit 14 (step Sc4). The process in the registration management apparatus 40 that has received the registration deletion request is the same as the registration deletion process shown in FIG.

  For example, in the case of a wireless communication terminal whose expiration date is determined in advance by the prepaid method, the registration management device 40 stores the registration information of the wireless communication terminal stored in the registration management device 40 when the expiration date is exceeded. It can be deleted by transmitting a registration deletion request from the wireless communication terminal. Therefore, the registration information of the wireless communication terminal 10 such as a mobile phone terminal that has become unusable after the expiration date is deleted from the registration information storage circuit 42 of the registration management device 40, so that the resource of the registration management device 40 is made effective. Can be used.

FIG. 9 is a flowchart showing the registration deletion process of the wireless communication terminal 10 in which the valid count is set in the usage information storage circuit 13 in advance.
First, when the wireless communication terminal 10 performs wireless communication with another wireless communication terminal 10 via the wireless base station 30, the terminal state detection circuit 12 detects the wireless communication and stores it in the terminal state storage circuit 11. The latest usage count is detected by reading the current usage count information and adding 1 to the usage count value indicated by the read usage count information. At this time, the latest usage count information is recorded in the terminal state storage circuit 11 (step Sd1). Next, the terminal registration deletion determination circuit 13 reads valid number-of-times information set in advance from the usage information storage circuit 14. Then, the terminal registration deletion determination circuit 13 compares the usage count detected by the terminal status detection circuit 12 with the valid count indicated by the valid count information read from the usage information storage circuit 14, and the usage count exceeds the valid count. It is determined whether or not (step Sd2). And when the frequency | count of use does not exceed the effective frequency | count, it returns to the process of step Sd1. On the other hand, when the usage count exceeds the valid count, the terminal registration deletion determination circuit 13 reads the wireless communication terminal identification information from the usage information storage circuit 14 and transmits a registration deletion request including the read wireless communication terminal identification information. Instruction information is transmitted to the wireless data processing circuit 16. The wireless data processing circuit 16 causes the wireless transmission / reception circuit 18 to transmit a wireless signal including a registration deletion request to the wireless base station 30 via the antenna 22 via the wireless interface circuit 17 (step Sd3). Then, the terminal registration deletion determination circuit 13 deletes the information stored in the usage information storage circuit 14 (step Sd4). The process in the registration management apparatus 40 that has received the registration deletion request is the same as the registration deletion process shown in FIG.

  By the above processing, for example, in the case of a wireless communication terminal in which the effective number of times is predetermined in a prepaid terminal, when the effective number is exceeded, the registration management device 40 stores the wireless communication terminal Registration information can be deleted by sending a registration deletion request from the wireless communication terminal. Therefore, the registration information of the wireless communication terminal 10 such as a mobile phone terminal that has become unusable after the effective number of times is deleted from the registration information storage circuit 42 of the registration management device 40, so that the resources of the registration management device 40 are made effective. Can be used.

  Note that when the wireless communication terminal 10 performs wireless communication with another wireless communication terminal 10 via the wireless base station 30, which is the timing at which the terminal state detection circuit 12 detects use frequency information, wireless communication is performed. It may be started, but in order to avoid registration deletion processing during wireless communication, it should be performed after the end of the wireless communication or after a certain amount of time has elapsed after the end. May be.

  FIG. 10 illustrates a process in which the wireless communication terminal 10 transmits a registration deletion request to the registration management device 40 based on the remaining capacity value of the battery 19 in FIG. This is a registration deletion process to which a process (step Sa3) for setting a communication cycle shorter than the state is added. By shortening the communication cycle from the normal communication state, the communication standby time, that is, the non-communication time with the radio base station 40 can be reduced, and the battery consumption during the communication standby time can be reduced. . Further, by making the communication cycle shorter than the normal communication cycle, the number of times of repeating communication can be increased between the wireless communication terminal 10 and the wireless base station 40 that may cause transmission data errors or the like. Thereby, it is possible to increase the probability that the registration management device 40 receives the registration deletion request.

  The above-described wireless communication terminal and registration management apparatus have a computer system inside. The registration deletion process described above is stored in a computer-readable recording medium in the form of a program, and the above process is performed by the computer reading and executing this program. Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.
