Problems solved by technology

[0007] In the above process, if the correct SMSC address is written in the SIM (Subscriber Identity Module, customer identification module) card, and the UE uses the SMSC address in the SIM card when sending a short message, the calling MSC can read from the short message. Get the correct SMSC address; however, if the wrong SMSC address is written in the SIM card, or the UE does not use the SMSC address in the SIM card when sending a short message, or the SMSC address in the SIM card is modified, the calling MSC cannot The correct SMSC address is read from the short message, so that the short message cannot be sent to the correct calling SMSC, and the sending of the short message fails

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...

Abstract

The invention discloses a short message transmission method, a system and equipment. The method comprises steps that: a calling eMSC receives a short message from calling UE; the calling eMSC determines whether a SMSC address contained in the short message, such as a short message center address, is correct; if no, the calling eMSC utilizes calling IMSI contained in the short message to query a pre-stored SMSC address table to acquire an SMSC address corresponding to the calling IMSI, and the queried SMSC address is further utilized to send the short message to the corresponding SMSC, and the SMSC sends the short message to a called UE; if yes, the calling eMSC utilizes the SMSC address contained in the short message to send the short message to the corresponding SMSC, and the SMSC sends the short message to the called UE. According to the method, the calling eMSC can acquire the correct SMSC address on the basis of the SMSC address table, the short message is sent to the correct calling ownership SMSC, so failure in sending the short message is avoided, the SMSC address correcting rate is improved greatly, and the sending success rate of the short message is improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a short message transmission method, system and equipment. Background technique [0002] In the prior art, the short message sending process is as follows figure 1 As shown, the sending process includes the following steps: [0003] Step 101: The calling UE (User Equipment, user equipment) sends a short message to the calling MSC (Mobile Switching Center, mobile switching center), and the calling MSC reads the calling home SMSC (Short Message Service Center, short message) from the short message. The SMSC address of the service center) is the address of the short message service center, or short message center address for short. [0004] Step 102: The calling MSC uses the SMSC address to send the short message to the calling home SMSC. [0005] Step 103, the calling home SMSC uses the called IMSI (International Mobile Subscriber Identification Number) carried in the short m...
