Embodiment 1
[0038] In view of the problems in the prior art, the first embodiment of the present invention provides a short message transmission method to figure 2 It is a schematic diagram of the system structure of an embodiment of the present invention. The method is applied to a system including eMSC (that is, the improved MSC proposed in the embodiment of the present invention), SMSC, and eHLR (that is, the improved HLR proposed in the embodiment of the present invention). Among them, the improved MSC (ie, eMSC) proposed in the embodiment of the present invention, in addition to the original call processing and switching control of the MSC, realizes location registration, call connection, handover, automatic roaming, and traffic control of mobile users. In addition to functions such as charging and base station control, it also needs to have the functions of receiving and storing the SMSC address sent by the HLR, and judging and detecting the SMSC address in the short message sent by t...
Embodiment 2
[0053] Based on the same inventive concept as the above method, the second embodiment of the present invention provides a short message transmission method, such as Figure 4 As shown, the short message transmission method includes the following steps:
[0054] Step 401: The calling UE sends a location update request message to the calling eMSC.
[0055] Step 402: The calling eMSC sends a location update request message to the eHLR.
[0056] Step 403: After receiving the location update request message, the eHLR uses the calling IMSI carried in the location update request message to query the local SMSC address table to obtain the SMSC address of the calling home SMSC corresponding to the calling IMSI, and send the insert to the calling eMSC User data message. The insert user data message carries the correspondence between the calling IMSI and the SMSC address of the calling SMSC.
[0057] Step 404: The calling eMSC sends a user data insertion response message to the eHLR.

Embodiment 3
[0068] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a short message transmission system. The short message transmission system specifically includes:
[0069] The home location register eHLR is used to store the corresponding relationship between the calling international mobile subscriber identity IMSI and the SMSC address of the calling SMSC in the local short message service center SMSC address table, and to compare the calling IMSI with the calling IMSI The correspondence between the SMSC addresses of the home SMSC is sent to the calling mobile switching center eMSC;
[0070] The calling eMSC is used to receive the correspondence between the calling IMSI from the eHLR and the SMSC address of the calling SMSC, and store the correspondence between the calling IMSI and the SMSC address in the local SMSC address table And, receiving a short message from the calling user equipment UE, and determining whether the SMSC a...
