Description

Service use system, service use apparatus, subscriber card substitute, and subscriber card substitute method

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

Mobile phone terminals (hereinafter referred to as 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 mobile phone service subscribers. SIM information is stored in the SIM card. The SIM information is information necessary for using the cellular phone service (user essential information). The SIM information includes an identification number (IMSI (International Mobile Subscriber Identity)), a user identification number (PIN (Personal Identification Number) code), location information, authentication information, a password, and the like for identifying the SIM card.

Since the SIM card can be attached to any portable terminal having the same communication standard, the user can change and use the portable terminal to which the SIM card is attached according to the situation. However, only one SIM card is issued with a one-line contract. For this reason, even a user who has a plurality of mobile terminals due to replacement or transfer of mobile terminals, only one mobile terminal with a SIM card can be used for communication.

Since the SIM card needs to be turned off before inserting / removing the SIM card, most portable terminals have a structure in which the SIM card cannot be inserted / removed without removing the battery in the casing of the portable terminal. Yes. For this reason, the insertion and removal of the SIM card is a troublesome work. Further, because of the above structure of the mobile terminal, the SIM card is not intended to be frequently inserted and removed, and therefore, the SIM card may be damaged if the insertion and removal are repeated frequently. In addition, since the SIM card is small in size for mounting on a mobile terminal, there is a possibility that the SIM card may be lost upon insertion / extraction.

Therefore, Patent Document 1 describes an alternative to a subscriber card that allows a mobile phone service to be used without any inconvenience without using a SIM card from a certain device and using a device different from that device. An alternative to a 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 that stores user essential information (SIM information) stored in the SIM card of the base unit, and a second communication unit that communicates with a service using device (mobile terminal) for using a mobile phone service (Connection part). Since the slave unit functions as a substitute for the SIM card, it has the same shape as the SIM card.
