Embodiment Construction
[0048] In order for those skilled in the art to better understand the technical solutions of the present invention, a card writing method and a client device provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0049] see figure 1 , is a schematic flowchart of a method for writing a card provided by an embodiment of the present invention, such as figure 1 As shown, the card writing method includes:
[0050] Step S10, when the terminal receives the start instruction, initiates a card replacement request to the network side;
[0051] Step S20, the terminal receives the card writing data short message sent by the network side;
[0052] Step S30, after the terminal receives the short message of writing card data, it performs a confirmation operation according to the short message of writing card data;
[0053] Step S40, after receiving the second confirmation message sent by the network side, the termina...

The embodiment of the invention provides a card writing method and a client terminal device. The card writing method includes the steps of S10, a terminal initiates a card changing request to the network side when receiving a starting command; S20, the terminal receives a card writing data message transmitted by the network side; S30, after receiving the card writing data message, the terminal conducts confirmation operation according to the card writing data message; S40, after receiving a secondary confirmation message transmitted by the network side, the terminal executes card writing operation on a USIM card connected with the terminal according to the card writing data message. By means of the card writing method and the client terminal device, the operation process in the card changing service is simplified, and advertisement and popularization of the card changing service are easier. In addition, service interruption caused by not-in-time operation or operation errors of a user or an operator is avoided, and the successful rate of the card changing service is improved.
Description
technical field [0001] The present invention relates to the field of mobile communications, in particular to a card writing method and a client device. Background technique [0002] In the field of domestic mobile communication, in the process of upgrading 2G / 3G network to 4G / LTE network, a large number of users need to complete the replacement of SIM (Subscriber Identity Module, Subscriber Identity Module) cards to USIM (UMTS Subscriber Identity Module, UMTS Subscriber Identity Module) cards. In the 2G / 3G network, the authentication algorithm of the SIM card adopts the COMP128 algorithm, and in the 4G / LTE (Long Term Evolution, 3GPP long-term evolution) network, the USIM card authentication algorithm adopts the Milenage algorithm. The related processes and interface messages of network authentication, encryption and integrity protection are designed based on the Milenage algorithm. Therefore, customers who purchase the operator's client equipment through the USIM card channe...
