SIM router device, communication terminal device, method of routing, and method of manufacturing SIM
A SIM router device is configured to access a SIM that stores a first authentication application and a second authentication application. The SIM router device includes a first input interface, a second input interface, a mapping information storage unit, and a controller. The mapping information storage unit is configured to acquire an authentication application list that lists the first authentication application and the second authentication application from the SIM, and store a mapping information in which the first input interface is associated with the first authentication application and the second input interface is associated with the second authentication application. The controller is configured to route, based on the mapping information, a first instruction received by the first input interface to the first authentication application of the SIM, and a second instruction received by the second input interface to the second authentication application of the SIM.
1. A SIM router device configured to access a single SIM that stores a first authentication application and a second authentication application, the SIM router device comprising:
a first input interface connected with a wireless baseband device that is configured to perform wireless communication;
a second input interface connected with the wireless baseband device, the first input interface being different from the second input interface;
a mapping information storage unit configured to
acquire an authentication application list that lists the first authentication application and the second authentication application from the single SIM, and
store a mapping information in which the first input interface is associated with the first authentication application and the second input interface is associated with the second authentication application; and
a controller configured to route, based on the mapping information,
a first instruction received by the first input interface from the wireless baseband device to the first authentication application of the single SIM, and
a second instruction received by the second input interface from the wireless baseband device to the second authentication application of the single SIM.
2. The SIM router device according to claim 1 , wherein
when the controller routes the first instruction to the first authentication application, the controller routes the second instruction to the second authentication application after the controller receives a response to the first instruction from the single SIM.
3. The SIM router device according to claim 1 , wherein
an output logical channel of an output interface is associated with the mapping information.
4. The SIM router device according to claim 1 , wherein
input logical channels of the first input interface and the second input interface are associated with the mapping information.
5. The SIM router device according to claim 1 , wherein
a flag information indicating a selection state of an EF DIR is associated with the mapping information.
6. A communication terminal device comprising:
an antenna configured to receive a high frequency signal;
a wireless baseband device configured to perform wireless communication and convert the high frequency signal received by the antenna into a baseband signal; and
a SIM router device configured to
receive, from the wireless baseband device, a first instruction and a second instruction generated from the baseband signal, and
access a single SIM that stores a first authentication application and a second authentication application, wherein
the SIM router device includes
a first input interface connected with the wireless baseband device,
a second input interface connected with the wireless baseband device, the first input interface being different from the second input interface,
a mapping information storage unit configured to
acquire an authentication application list that lists the first authentication application and the second authentication application from the single SIM, and
store a mapping information in which the first input interface is associated with the first authentication application and the second input interface is associated with the second authentication application, and
a controller configured to route, based on the mapping information,
the first instruction received by the first input interface from the wireless baseband device to the first authentication application of the single SIM, and
the second instruction received by the second input interface from the wireless baseband device to the second authentication application of the single SIM.
7. A method of routing by a SIM router device configured to access a single SIM that stores a first authentication application and a second authentication application, the SIM router device including a first input interface and a second input interface connected with a wireless baseband device configured to perform wireless communication, the method comprising:
acquiring an authentication application list that lists the first authentication application and the second authentication application from the single SIM;
storing a mapping information in which the first input interface is associated with the first authentication application and the second input interface is associated with the second authentication application; and
routing, based on the mapping information, a first instruction received by the first input interface from the wireless baseband device to the first authentication application of the single SIM and a second instruction received by the second input interface from the wireless baseband device to the second authentication application of the single SIM;
wherein the first input interface is different from the second input interface.
