  In the state without the user permission for receiving the push notification, the reception itself of the first push notification and the second push notification by the push notification receiving unit 13 is prohibited. For this reason, the push notification receiving unit 13 closes the push notification receiving port in a state where the user permission for receiving the push notification is not given. As a result, unnecessary opening of the push notification receiving port can be avoided and security can be improved.

(Example 3 of port open conditions)
Example 3 of the port open condition is setting of service subscriber identification information (service subscriber ID) of the subscriber of the push notification service. As a user setting function of the terminal device 10, a service subscriber ID setting function is provided. The push notification receiving unit 13 checks whether the user setting data of the service subscriber ID is set or not set among the user setting data set by the user setting function of the terminal device 10. As a result of the confirmation, the push notification reception unit 13 determines that the port open condition is satisfied when the user setting data of the service subscriber ID is set. On the other hand, as a result of the confirmation, the push notification reception unit 13 determines that the port open condition is not satisfied when the user setting data of the service subscriber ID is not set.

  The service subscriber ID set by the user in the terminal device 10 is used for user authentication in the push notification service, for example. In this case, success of user authentication in the push notification service is an execution condition for transmitting the first push notification and the second push notification. Therefore, in the state where the service subscriber ID is not set, there is no problem even if the push notification receiving unit 13 cannot receive the first push notification or the second push notification by closing the push notification receiving port. As a result, unnecessary opening of the push notification receiving port can be avoided and security can be improved.

  The push notification receiving unit 13 may use any one of the above-described port open condition examples 1, 2, and 3 alone, or may use any combination thereof.
