Description

  The present invention relates to a service use system and the like that uses a subscriber card provided to a subscriber of a service and storing information necessary for using the service.

  2. Description of the Related Art Mobile phone terminals (hereinafter, mobile terminals) for using mobile phone services have become widespread. An IC card called a SIM (Subscriber Identity Module) card is used for the portable terminal. The SIM card is provided to a mobile phone service subscriber. SIM information is stored in the SIM card. The SIM information is information (user essential information) necessary to use the mobile phone service. The SIM information includes an identification number (IMSI (International Mobile Subscriber Identity)) for identifying the SIM card, a user identification number (PIN (Personal Identification Number) code), position information, authentication information, a password, and the like.

  Since the SIM card can be mounted on any mobile terminal having the same communication standard or the like, the user can change and use the mobile terminal on which the SIM card is mounted according to the situation. However, only one SIM card is issued with one line contract. Therefore, even if a user has a plurality of mobile terminals due to replacement or transfer of the mobile terminal, only one mobile terminal equipped with a SIM card can be used for communication.

  Since the power of the mobile terminal must be turned off before inserting or removing the SIM card, most mobile terminals have a structure in which the SIM card cannot be inserted or removed without removing the battery in the housing of the mobile terminal. I have. For this reason, inserting and removing the SIM card is a troublesome operation. Further, due to the above structure of the mobile terminal, the SIM card is not intended to be frequently inserted and removed, so that the SIM card may be damaged if insertion and removal are frequently repeated. Further, since the SIM card is small in size to be mounted on the mobile terminal, there is a possibility that the SIM card will be lost at the time of insertion and removal.

  Therefore, Patent Literature 1 describes an alternative to a subscriber card that allows a mobile phone service to be used without inconvenience by using a device different from the SIM card without removing the SIM card from the device. An alternative to the subscriber card (slave unit) described in Patent Document 1 is a first communication unit (short-range communication unit) that performs wireless communication with an external device (master unit) provided with a subscriber card (SIM card). ), A storage unit for storing user essential information (SIM information) stored in the SIM card of the base unit, and a second communication unit for communicating with a service using device (mobile terminal) for using a mobile phone service. (Connection part). The slave unit has the same shape as the SIM card to function as a substitute for the SIM card.
