All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The core idea of the invention is that the intelligent card obtains the IP address of the OTA server through the domain name of the OTA server, then performs service interaction with the OTA server, even if the subsequent IP address of the OTA server changes, the new IP address of the OTA server can still be found through the domain name, and then performs service interaction.
Referring to fig. 1, fig. 1 is a flowchart of a method for acquiring an OTA server IP address by a smart card according to an embodiment of the present invention, where the method includes the following steps:
s100, the intelligent card selects a proper OTA server IP address from the IP address list of the candidate OTA server to carry out service interaction with the OTA server.
Referring to fig. 2, fig. 2 is a flowchart illustrating an interaction between a smart card and an OTA server according to an embodiment of the present invention, which includes the following steps:
(11) the smart card checks if there is a candidate OTA server IP address column.
Firstly, the smart card checks whether a candidate OTA server IP address list exists, if not, the smart card acquires the OTA server IP address through the candidate domain name server IP address list, and the specific operation steps of the method are as follows in S200.
(12) And the intelligent card traverses the IP address list of the OTA server and tries to interact with the OTA server until the intelligent card can normally interact with the OTA server.
If the candidate OTA server IP address list exists, the intelligent card selects the OTA server IP address in turn from the candidate OTA server IP address list to try to interact with the OTA server, and traverses the OTA server IP address list until the intelligent card finds the correct OTA server IP address, so that the intelligent card can establish connection with the OTA server to perform normal service interaction.
(13) And if the correct OTA server IP address can not be found from the OTA server IP address list, acquiring the OTA server IP address through the domain name server IP address.
When the candidate OTA server IP address list is traversed and the smart card can not normally interact with the OTA server all the time, the smart card acquires the OTA server IP address through the candidate domain name server IP address list, and the specific operation steps of the method are as follows in S200.
S200, if the IP address list of the candidate OTA server does not exist or the intelligent card can not normally interact with the OTA server, the IP address of the OTA server is obtained through the IP address list of the candidate domain name server.
Referring to fig. 3, fig. 3 is a flowchart illustrating interaction between a smart card and a domain name server according to an embodiment of the present invention, which includes the following steps:
(21) the smart card checks if there is a list of candidate domain name server IP addresses.
The smart card checks whether a list of candidate domain name server IP addresses exists, and if not, the smart card acquires the OTA server IP address by interacting with the smart terminal, and the specific operation steps of the method are as follows S300.
(22) If the candidate domain name server IP address list exists, the intelligent card sequentially selects the domain name server IP addresses from the candidate domain name server IP address list, sends a connection request to the domain name server, and traverses the candidate domain name server IP address list until the intelligent card can establish connection with the domain name server.
(23) After the intelligent card can establish connection with the domain name server, the intelligent card sends a domain name resolution request to the domain name server, and the domain name server returns the resolved latest OTA server IP address to the intelligent card according to the domain name of the OTA server.
(24) The smart card updates the latest OTA server IP address into the list of candidate OTA server IP addresses.
(25) If all the domain name server IP address lists are traversed and no OTA server IP address is found, the intelligent card acquires the OTA server IP address through interaction with the intelligent terminal, and the specific operation steps of the method are as follows S300.
And S300, if the IP address list of the candidate domain name server does not exist or the OTA server IP address cannot be acquired, acquiring the latest OTA server IP address by interacting with the intelligent terminal.
If the candidate domain name server IP address list does not exist or the list exists but the OTA server IP address still cannot be acquired, the currently stored domain name server IP address temporarily cannot inquire the required OTA server IP address, the latest domain name server IP address needs to be acquired through the terminal, and then the IP address of the terminal is acquired through the domain name of the OTA server. Meanwhile, the latest domain name server IP address needs to be updated into a candidate domain name server IP address list, and the acquired OTA server IP address needs to be updated into a candidate OTA server IP address list.
Referring to fig. 4, fig. 4 is a flowchart illustrating an interaction between a smart card and a smart terminal according to an embodiment of the present invention, which includes the following steps:
(31) the intelligent card interacts with the intelligent terminal, and the latest domain name server IP address is obtained through the intelligent terminal;
(32) the smart card interacts with the corresponding domain name server through the acquired latest domain name server IP address, and acquires the latest OTA server IP address through the domain name server, and the specific operation of the step is shown in the step (24) in the above S200;
(33) the intelligent card updates the IP address of the latest domain name server into a candidate domain name server IP address list;
(34) the smart card updates the IP address of the most recent OTA server into the list of candidate OTA server IP addresses.
