The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Example 1

[0026] Reference Figure 1 This embodiment discloses a method for dynamically configuring a short message center number, including the following steps S100 to S300:

[0027] Step S100: receiving a short message center number update request sent regularly by an electronic card, wherein the short message center number update request includes the IMSI (International Mobile Subscriber Identity) of the electronic card.

[0028] Step S200: extracting the IMSI of the electronic card from the SMS center number update request, and acquiring the corresponding first SMS center number from the SMS center number configuration list according to the IMSI of the electronic card.

[0029] Step S300, generating a corresponding SMS center number update instruction according to the first SMS center number, encrypting the SMS center number update instruction for transmission and returning it to the electronic card, so that the electronic card updates the current SMS center number according to the SMS center number update instruction.

[0030] The above steps S100 to S300 may be executed by, for example, a server or software deployed on the server. The method of this embodiment will be described in detail from two aspects, the electronic card and the server.

[0031] The electronic card in this embodiment takes a (U)SIM card as an example. Figure 2 , perform the following steps:

[0032] 1) The (U) SIM card starts the first timer to regularly trigger the task of updating the SMS center number.

[0033] Specifically, the IP address and port number of the server are preset in advance in the (U)SIM card, and a timer is configured to trigger the task of updating the SMS center number at a preset time; for example, the task of updating the SMS center number is triggered once a day.

[0034] 2) (U) SIM card reads the IMSI of the current card and the SMSP number in the current card.

[0035] 3) (U) SIM card creates a BIP protocol channel, carries the IMSI and current SMS center number in the SMS center number update request and sends the request to receive the SMS center number update instruction returned by the server through the BIP protocol channel.

[0036] 4) (U) The SIM card receives the update instruction to the SMS center number and completes the message parsing.

[0037] 5) (U) SIM card transmits and decrypts the SMS center number update instruction.

[0038] Specifically, in this embodiment, the SMS center number update instruction is decrypted by transmission key.

[0039] The method for obtaining the transmission key includes: based on the 3DES-ECB method, using the IMSI as a discrete factor, using a preset root password (such as a 32-bit root password agreed in advance) to obtain the transmission key after a preset number of times (such as 2 times).

[0040] 6) (U) The SIM card determines whether the SMS center number in the SMS center number update instruction is consistent with the SMS center number in the current card (equivalent to the current SMS center number); if not, the update instruction is executed to update the SMS center number in the current card to the SMS center number in the SMS center number update instruction.

[0041] By regularly establishing a BIP protocol channel with the server, sending an update request to the server through the BIP protocol channel, and carrying the (U)SIM card SMS center number, and receiving the SMS center update instruction sent by the server through the BIP protocol channel, the problem of the SMS center being unable to send SMS due to user misoperation or malicious attacks can be effectively solved.

[0042] Correspondingly, the (U)SIM card of this embodiment includes: Figure 3The modules shown. A timing module, used to trigger a text message center number update request at a fixed time. A BIP sending module, used to send a text message center number data update request to the server through the BIP protocol channel. Wherein, the text message center number data update request includes: the IMSI of the current card and the current text message center number. A BIP receiving module, used to receive the data message responded by the server, including the text message center number update instruction. A data decryption module, used to transmit and decrypt the data decryption module. A second update module, used to compare the current text message center number with the text message center number in the text message center number update instruction, and perform an update operation according to the comparison result. In this embodiment, the second update module is an application developed based on the U (SIM) card standard specification, which is used to parse and execute the text message number update instruction. It can be installed at the factory, or it can be downloaded and installed remotely through OTA technology at a later time. Its main function is to complete the update of the text message center number.

[0043] Reference Figure 4 In this embodiment, the server receives the SMS center number update request sent by the (U)SIM card and executes the following steps:

[0044] 1) A request for updating the SMS center number is received, and the IMSI of the electronic card and the current SMS center number included in the request are extracted.

[0045] 2) Reverse the 7-digit number segment from the IMSI. The IMSI is defined by the number segment according to a fixed rule. Therefore, the number segment corresponding to the IMSI can be reversed according to the fixed rule.

[0046] 3) Obtain the corresponding first SMS center number from the SMS center number configuration list according to the number segment.

[0047] Specifically, the SMS center number configuration list includes: the mapping relationship between city information (equivalent to the affiliated city information) and the SMS center number and the first relationship table. The first relationship table includes: city information, switch information and number segments. A single city information may include at least one switch information, and a single switch information may include at least one number segment. The content in the first relationship table can be stored in the same table or in different tables. Based on the SMS center number configuration list, the corresponding switch and the city information where the switch is located can be determined based on the number segment, and then the first SMS center number is determined through the city information.

[0048] 4) Compare the first SMS center number with the current SMS center number extracted in the SMS center number update request to determine whether they are consistent. If they are consistent, return a response result indicating that no update is required. Otherwise, proceed to the next step.

[0049] 5) Generate a corresponding SMS center number update instruction according to the first SMS center number. The update instruction carries the first SMS center number.

[0050] 6) Encrypt the SMS center number update instruction for transmission and return the update instruction.

[0051] Obviously, in some embodiments, the server may not perform the comparison operation in step 4), but directly generate a corresponding SMS center number update instruction according to the first SMS center number and return it to the (U)SIM card. The (U)SIM card may not compare the current SMS center number with the SMS center number in the SMS center number update instruction, but directly perform the SMS center number update operation.

[0052] The server needs to maintain the mapping relationship between the city information (equivalent to the city information) in the SMS center number configuration list and the SMS center number. In addition, the server in this embodiment also includes: based on the scheduled task, the card resource library is checked for data according to the SMS center number configuration list, and the card resource library is updated; wherein the card resource library stores the card data information corresponding to the electronic card. That is, the card resource library is the card data information library corresponding to the electronic card. At this time, when the card data is set incorrectly due to human factors, the background will promptly discover and generate an abnormal data list.

[0053] Specifically, refer to Figure 5 , perform data verification on the card resource library, including performing the following steps:

[0054] 1) Start the second timer to regularly trigger the data verification task of the card resource library.

[0055] Specifically, for example, the data verification task of the card resource library may be triggered once a day.

[0056] 2) Connect to the card resource library to obtain incremental card resource data.

[0057] 3) Traverse the incremental card resource data, based on the SMS center number configuration list, check the SMS center number in the last resource library, and generate a list of card data to be updated.

[0058] Specifically, since the SMS center number configuration list is a standard basis and the card resource data is a dynamic service, if the SMS center number in the card resource data is inconsistent with the SMS center number in the SMS center number configuration list, the SMS center number in the card resource data needs to be corrected (i.e., it is determined that there is an erroneous SMS center number in the card resource data). The card resource data whose SMS center number needs to be corrected is added to the list of card data to be updated.

[0059] Each piece of card data to be updated in the card data to be updated list, for example, includes: an identifier of the card data to be updated in the card resource library and an updated SMS center number, etc.

[0060] If the SMS center numbers in all incremental card resource data are correct, the card data list to be updated is empty, and the next step is not executed.

[0061] 4) According to the card data list to be updated, the SMS center number of the corresponding data in the card resource library is corrected.

[0062] This embodiment sends a SMS center number update request through an electronic card at regular intervals, and updates the SMS center number in the electronic card, so that the user can realize dynamic and silent update of the SMS center number without being aware of it, avoiding customer complaints caused by unsuccessful SMS sending, and improving the management level and customer satisfaction of the operator. In addition, this embodiment can check the abnormal data in the card resource library by associating with the card resource library data, and complete the imperceptible data synchronization of the SMS center number on the card side and in the card resource data. At the same time, this embodiment can solve the practical problems of abnormal batch SMS center data settings generated in the card data generation stage, card writing stage, data storage stage, etc. in large quantities, and can avoid the occurrence of serious production accidents.

[0063] Example 2

[0064] Reference Figure 6 This embodiment discloses a system for dynamically configuring a short message center number, including: a request receiving module, a configuration management module, a first acquisition module, and an update response module.

[0065] The request receiving module is used to receive the SMS center number update request sent by the electronic card at a fixed time, and extract the IMSI of the electronic card from the SMS center number update request.

[0066] The configuration management module is used to configure the SMS center number configuration list. Specifically, the SMS center number configuration list includes: the mapping relationship between the city information (equivalent to the belonging city information) and the SMS center number and the first relationship table. The first relationship table includes: city information, switch information and number segments. A single city information may include at least one switch information, and a single switch information may include at least one number segment.

[0067] The first acquisition module is used to acquire the corresponding first SMS center number from the SMS center number configuration list according to the IMSI of the electronic card. Specifically, based on the SMS center number configuration list, the corresponding switch and the city information where the switch is located can be determined based on the number segment, and then the first SMS center number is determined based on the city information.

[0068] The update response module is used to generate a corresponding SMS center number update instruction according to the first SMS center number, and return the SMS center number update instruction to the electronic card after transmission encryption, so that the electronic card updates the current SMS center number according to the SMS center number update instruction.

[0069] Reference Figure 6 The system of this embodiment also includes: a first update management module and a card resource management module. The first update management module is used to check the data of the card resource library based on the scheduled task and the SMS center number configuration list to generate a list of card data to be updated. The card resource library stores card data information corresponding to the electronic card. The card resource management module is used to manage the card resource library, including, for example, updating the SMS center number in the card resource library according to the list of card data to be updated. In some other embodiments of the present invention, the first update management module and the card resource management module (not shown) may not be included.

[0070] Similar to Example 1, this embodiment sends a SMS center number update request through an electronic card at regular intervals, and updates the SMS center number in the electronic card, so that the user can realize dynamic and silent update of the SMS center number without being aware of it, avoiding customer complaints caused by unsuccessful SMS sending, and improving the management level and customer satisfaction of the operator. In addition, in this embodiment, by associating with the card resource library data, it is possible to check the abnormal data in the card resource library, and complete the imperceptible data synchronization of the SMS center number on the card side and in the card resource data.
