Flowchart 1; and FIG. 5 is a flow chart 2 of a short message processing method in accordance with a preferred embodiment of the present invention. BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. This embodiment provides a short message processing method. FIG. 1 is a flowchart of a short message processing method according to an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps S102 to S106. Step S102: Parse the originating MSC address carried by the received short message. Step S104: Acquire a visited MSC address corresponding to the sending number of the short message. Step S106: Determine that the MSC address is inconsistent with the visited MSC address, and refuse to process the short message. Through the above steps, it is determined whether the MSC address carried by the short message is consistent with the visited MSC address corresponding to the short message transmission number. If the MSC address of the short message is determined to be falsified, the MSC is overwritten. In the related art, the operator cannot filter out the problem caused by the falsified short message. For example, the short message of the international roaming changes the MSC address of the calling to the domestic MSC address, and compares the MSC address carried in the short message. The visiting MSC of the short message identifies that the short message has been tampered with, and avoids charging inaccuracy caused by charging the short message, thereby improving the accuracy of charging. If the received MSC address is obtained for each received short message, this method will result in a relatively large network load. As a preferred implementation, the MSC address is not in the legal MSC address list, and the MSC address corresponding to the sending number of the short message is obtained by using a legal MSC address list, where the legal MSC address list is obtained. The short message corresponding to the MSC address is a short message for direct processing. In this implementation manner, a legal list is determined, and the MSC address outside the legal list is compared with the visited MSC address to determine whether the short message is tampered with, so that it is not necessary to compare all the short messages. The operation reduces the network load, and at the same time, avoids the misidentified hacked SMS when the legitimate user switches between different MSCs. The method for determining whether the MSC address is a preset legal MSC address list is as follows: determining that the MSC address is inconsistent with the visited MSC address in the following manner: determining whether the visited MSC belongs to an address in the preset legal MSC address list; Yes, it is determined that the MSC address is inconsistent with the visited MSC address. The method determines whether the MSC address and the visited MSC address are consistent by means of indirect judgment. At the same time, it should be directly determined whether the MSC address and the visited MSC address are consistent. The above two methods improve the flexibility of the method for determining whether the MSC address and the visited MSC address are consistent. In another preferred embodiment, the visited MSC address may be obtained from the HLR. For example, a Send Routing Information (SRI) routing request message may be sent to the HLR, and the response message corresponding to the SRI routing request message is carried in the response message.

The following description will be made in conjunction with the preferred embodiments, and the following preferred embodiments incorporate the above-described embodiments and preferred embodiments. Preferred Embodiment 1 This embodiment provides a short message processing method, which includes the following steps: Step S302: A terminal (for example, a mobile phone) sends a short message to a short message center, and the short message center decodes the message. Step s304: The terminal sends to the Home Location Register (HLR)

The SRI routes the request information, and requests the source number to visit the MSC address. Step S306: The short message center obtains the source code visited by the MSC address carried in the response message corresponding to the SRI request. Step S308: The short message center determines whether the MSC address is falsified according to the predetermined policy. If the judgment result is falsified, the MO response is rejected and the short message is rejected, otherwise the subsequent processing of the MO call process is continued. This embodiment modifies the calling process in the related art. In the related art, the mobile phone submits a message to the short message center, and the short message center decodes the message, checks the number specification, enters the library, issues the bill, and the like, and then returns to the MO successfully. For the mobile phone, the whole process checks whether the MSC address has been falsified or not. In this embodiment, the source MSC that obtains the short message is added in the calling process, and compared with the MSC in the originating message, in the case of inconsistency. Next, it is judged to be an illegal short message, and the rejection is processed. The preferred embodiment improves the acquisition of the source MSC of the short message and compares it with the MSC in the originating message, thereby avoiding adding additional equipment and making no major changes to the original system. The second embodiment of the present invention provides a method for detecting a fraudulent short message. In this embodiment, the short message center stores an MSC GT address, or is called a Trusted GT. The list can be configured by the short message center. For maintenance, FIG. 4 is a flowchart 1 of a short message processing method according to a preferred embodiment of the present invention. As shown in FIG. 4, the method includes the following steps. Step S402: The MS submits the message MO to the short message center. Step S404: The short message center determines whether the calling MSC address is the trusted MSC address of the local network. If the determination result is yes, step S406 is performed; otherwise, step S408 is performed. Step S406: No processing is performed, which is processed according to the mobile originating call (MO) message flow in the related art. Step S408: Send SRI_SM to the HLR, requesting the VMSC_GT information of the calling user. Step S410: Feedback MO_ACK to the user. The second embodiment of the present invention provides a method for detecting a fraudulent short message. In this embodiment, the short message center stores an MSC GT address, or is called a Trusted GT. The list can be configured by the short message center. To maintain, in this embodiment, a short message that is not called by the local network GT is processed. FIG. 5 is a second flowchart of a short message processing method according to a preferred embodiment of the present invention. As shown in FIG. 5, the method includes: Step S502: The MS submits the message MO to the short message center. Step S504: The SMS center detects that the originating MSC address is not the trusted MSC address of the local network. Step S506: The short message center sends an SRI route request message requesting source number routing information. Step S508: The HLR returns the visited MSC address of the source user. Step S510: The SMS center compares whether the returned visited MSC address is consistent with the originating MSC address. If yes, step S512 is performed; otherwise, step S514 is performed. Step S512: The short message is considered to be a valid short message, and the short message center returns to the MO to successfully respond. The message continues to be processed in step S514: the fraudulent short message is considered, and the short message center returns a MO failure response, and the message processing ends. The third embodiment of the present invention provides a method for detecting a fraudulent short message. In this embodiment, the short message center stores an MSC GT address, or is a list of trusted GTs. The list can be maintained by the configuration module of the short message center. In this embodiment, the short message that is not called by the local network GT is processed, and the method includes: Step S601: The MS submits the message MO to the short message center. Step S604: The SMS center detects that the originating MSC address is not the trusted MSC address of the local network. Step S606: The short message center sends an SRI route request message request source number routing information. Step S608: The HLR returns the visited MSC address of the source user. Step S610: The short message center checks whether the returned MSC address is in the local network trust MSC GT list. Step S612: If the returned MSC address is not in the list, it is considered to be a legal short message, and the short message center returns to the MO successfully, and the message continues to be processed. Step S614: If the returned MSC address is in the list, it is considered to be a fraudulent short message, and the short message center returns to the MO failure response, and the message processing ends. Through the foregoing embodiments, a short message processing method and device are provided. After the fraud detection short message function is built in the short message center, the MO process in the related technology is not greatly changed, but the request source is added in the MO message processing process. The number routing information and the verification source number are visited by the MSC address. In order to save network resources, the SMS center needs to maintain the MSC GT address of the local network. The messages originating from the MSC of the local network are considered to be legal, and there is no need to send a routing request message. This can effectively prevent users from being mistakenly detected as fraudulent short messages when switching between different MSCs on the network, and also saves network resources and reduces the load on the HLR. For the message that the non-local network trusts the MSC address to start, it needs to send the routing information of the SRI request source number, and judge whether the message is a fraudulent message according to the returned visited MSC address.
