Terminal and method for managing secure devices
A mobile terminal and method for managing secure devices associated with the terminal are discussed. According to an embodiment, the method includes acquiring at least one of availability information and delegation information from each of at least one secure device associated with the mobile terminal; establishing a secure device delegation rule set for the at least one secure device based on the acquired information; receiving a request for establishing a communication connection with a secure device from a server; and establishing a communication connection between the server and one of the at least one secure device based on the secure device delegation rule set.
1. A method for managing communication between a server and a subscriber identification module (SIM) card associated with a mobile terminal by using the mobile terminal, the method comprising:
acquiring first availability information indicating whether a first SIM card is available and second availability information indicating whether a second SIM card is available, wherein the first SIM card and the second SIM card are equipped in a same mobile terminal;
establishing a SIM card delegation rule based on the first availability information and the second availability information;
receiving a request for establishing a communication connection with the first SIM card from the server;
if the first SIM card is determined to be available, establishing a communication connection between the server and the first SIM card; and
if the first SIM card is determined to be unavailable and the second SIM card is determined to be used instead of the first SIM card based on the SIM card delegation rule, determining whether the second SIM card is available, and establishing a communication connection between the server and the second SIM card if the second SIM card is determined to be available.
2. The method of claim 1 , further comprising:
if the first SIM card is determined to be unavailable, storing update information from the server in the second SIM card through the established communication connection; and
transferring the stored update information from the second SIM card to the first SIM card once the first SIM card is available.
3. The method of claim 1 , wherein the communication connection is an over the air (OTA) connection or a Session Initiation Protocol (SIP) session.
4. The method of claim 1 , wherein the first availability information is acquired from the first SIM card, and the second availability information is acquired from the second SIM card.
5. The method of claim 4 , further comprising:
acquiring, from the first SIM card, first delegation information indicating a SIM card to be used instead of the first SIM card when the first SIM card is unavailable; and
acquiring, from the second SIM card, second delegation information indicating a SIM card to be used instead of the second SIM card when the second SIM card is unavailable,
wherein the SIM card delegation rule is established further based on the first delegation information and second delegation information.
6. The method of claim 1 , wherein the first SIM card is determined to be unavailable when a memory of the first SIM card is full.
7. A mobile terminal for managing communication between a server and a subscriber identification module (SIM) card associated with the mobile terminal, comprising:
a first SIM card and a second SIM card equipped in the mobile terminal;
a transceiver configured to transmit or receive a signal; and
a controller coupled to the first SIM card, the second SIM card, and the transceiver and configured to:
acquire first availability information indicating whether a first SIM card is available and second availability information indicating whether a second SIM card is available;
establish a SIM card delegation rule based on the first availability information and the second availability information;
receive a request for establishing a communication connection with the first SIM card from the server;
if the first SIM card is determined to be available, establish a communication connection between the server and the first SIM card; and
if the first SIM card is determined to be unavailable and the second SIM card is determined to be used instead of the first SIM card based on the SIM card delegation rule, determine whether the second SIM card is available, and establish a communication connection between the server and the second SIM card if the second SIM card is determined to be available.
