Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a card writing method, including:
step 11, acquiring an identifier in a user card, wherein the identifier is used for indicating whether the user card needs to be written in a short message mode; specifically, the identifier pre-stored in the user card may be acquired through a communication interface between the user card and the terminal;
and step 13, writing the card in a short message mode after the successful attachment according to the attachment flow.
According to the scheme of the embodiment, the identification in the user card is obtained, and the identification is used for indicating whether the user card needs to be written in a short message mode; when the identification indicates that the user card needs to be written with the short message, an attachment flow carrying indication information of the attachment type of the user card using the short message is initiated to a network side; and according to the attachment flow, after the attachment is successful, writing the card in a short message mode. The method can ensure that only the terminal with the short message card writing capability can initiate the attachment, and the network performs the joint attachment for the terminal according to the attachment request initiated by the terminal, thereby solving the problems of large network investment and incapability of distinguishing which terminals need to write the short message cards.
In this embodiment, the identifier is represented by one bit or more than 2 bits, but there may be other definitions, for example, the identifier may also be represented by a character.
If the bit is a bit, the first state of the bit indicates that the user card needs to be written in a short message mode, and the second state of the bit indicates that the user card does not need to be written in the short message mode; for example, the bit in the identifier is 1, the identifier needs to be written with a short message, and the bit is 0, and the identifier does not need to be written with a short message.
If the bit is more than 2 bits, the first state represented by the more than 2 bits indicates that the user card needs to be written with the short message mode, and the second state represented by the more than 2 bits indicates that the user card does not need to be written with the short message mode. For example, the bit in the identifier is 11, the identifier needs to be written with a short message, and the bit is 00, and the identifier does not need to be written with a short message.
If the identifier is represented by a character, for example, Y represents that the user card needs to be written in a short message mode, and F represents that the user card does not need to be written in a short message mode.
In this embodiment of the present invention, the specific implementation manner of the identifier is not limited to the above listed manner, and may also be implemented by other identifiers capable of identifying whether the card needs to be written in a short message manner.
In an embodiment of the present invention, the step 12 may specifically include:
step 121, when the identifier indicates that the user card needs to be written with a short message, an attachment request is initiated to a network side, and the attachment request carries indication information of a first attachment type which needs to use the short message to write with the card;
specifically, for example, when the identifier indicates that the user card needs to write a short message, an attach request is initiated to a mobile management entity MME on the network side, where the attach request carries indication information of an SMS only, and is used to indicate that the terminal writes the card in a short message manner.
And step 122, receiving a feedback message of an Evolved Packet System (EPS) attachment or a combined EPS/IMSI attachment process performed by the network side according to the attachment request.
Specifically, for example, the receiving MME initiates an EPS attach or a combined EPS/IMSI attach procedure to the mobile switching center MSC according to the attach request, and performs a feedback message of the EPS attach or the combined EPS/IMSI attach procedure.
Specific implementation examples are as follows:
example 1:
the identifier m1 is built in the user card, and the m1 can be one binary bit or a plurality of binary bits with unlimited length;
the mark is used for marking whether the user card needs to be written with the short message, if the bit position in the mark is 1, the mark needs to be written with the short message, and if the bit position is 0, the mark does not need to be written with the short message;
the terminal reads the mark in the user card through the interface between the user card and the terminal (module), if the read mark indicates that the user needs to write the card by short message, ESP (evolved packet system) attachment is initiated, and the ESP attachment carries the SMS only mark at the same time to indicate that the card needs to be written by short message; on the contrary, if the read identifier indicates that the short message card writing is not needed, a common attachment process can be initiated;
after receiving an attachment request message carrying SMS only, the MME initiates joint attachment to provide short message service capability for the terminal;
and if the card writing operation is carried out subsequently, the short message service is carried out.
When an ESP (evolved packet system) attachment is initiated, as shown in fig. 2, when a terminal initiates an attachment, an attach request message is sent, where the attach request message carries an attachment type, if the UE indicates sms only in the attach request, it indicates that the UE uses sms (short message) service, if the network uses an SGs interface (i.e., an interface between a mobility management entity MME and a mobile switching center MSC), but not an SGd interface (an interface between an MME and an SMSC), the MME initiates an attachment process to the MSC, so as to implement a joint attachment process of the terminal, and by performing joint attachment on the network side, the terminal can use the short message service.
Example 2:
the identifier m1 is built in the user card, and the m1 can be one binary bit or a plurality of binary bits with unlimited length;
the mark is used for marking whether the user card needs to be written with the short message, if the bit position in the mark is 1, the mark needs to be written with the short message, and if the bit position is 0, the mark does not need to be written with the short message;
the terminal reads the mark in the user card through the interface of the user card and the terminal (module), if the read mark indicates that the user needs to write the short message, the terminal initiates the joint EPS/IMSI (international mobile subscriber identity) attachment and carries the SMS only mark to indicate that the short message service needs to be used; on the contrary, if the read identifier indicates that the short message card writing is not needed, a common attachment process can be initiated;
after receiving an attachment request message carrying SMS only and indicating joint attachment, MME initiates joint attachment to provide short message service capability for a terminal;
and if the card writing operation is carried out subsequently, the short message service is carried out.
In the embodiment of the invention, the identifier in the user card is obtained, and the identifier is used for indicating whether the user card needs to be written in a short message mode; when the identification indicates that the user card needs to be written with the short message, an attachment flow of indication information of the attachment type of the short message card needing to be written with the short message is initiated to a network side; and according to the attachment flow, after the attachment is successful, writing the card in a short message mode. The method can ensure that only the terminal with the short message card writing capability can initiate the attachment, and the network performs the joint attachment for the terminal according to the attachment request initiated by the terminal, thereby solving the problems of large network investment and incapability of distinguishing which terminals need to write the short message cards.
