Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method and device for sending a welcome text message. Background Art

[0002] Currently, when a user terminal roams onto a satellite network, it receives a welcome SMS message from the SMS center. Related technologies incorporate a signaling gateway into the core network setup process to handle special roaming authorization for user terminals, including triggering the landing SMS platform to send a customized SMS message reminding users to sign up for satellite roaming rights. When a user terminal accesses the core network, it first connects to the core network's AMF (Access and Mobility Management Function) / MME (Mobility Management Entity). Then, via the DRA (Data Router Agent) and the signaling gateway, it connects to the home province's UDM (User Data Management Entity) for authentication. Simultaneously, the signaling gateway triggers the SMS center to send a welcome SMS message to the roaming user terminal. This indicates that in related technologies, the SMS center is triggered to send the welcome SMS message as soon as the user terminal accesses the network. However, at this point, the user terminal has not yet established a user plane, so the SMS message cannot be delivered to the user terminal. The SMS message must wait until the user completes the IP link establishment before it can be sent, resulting in excessive SMS center storage usage.

[0003] To address the above-mentioned problems, no effective solutions have been proposed so far. Summary of the Invention

It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0036] Figure 2 Flowchart of the method for sending a welcome SMS according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0037] Step S202, obtaining multiple time nodes in the process of the user terminal accessing the multimedia system;

[0038] Step S204, determining a target time for sending a trigger instruction to the SMS center based on the multiple time nodes, where the trigger instruction is used to trigger the SMS center to generate a welcome SMS message;

[0039] Step S206: After the user terminal accesses the multimedia system, an instruction message is sent to the SMS center. The instruction message is used to instruct the SMS center to send a welcome SMS message to the user terminal. The target time is before the time when the user terminal accesses the multimedia system.

[0040] Figure 3 A flow chart of a method for sending a welcome SMS message in related art is shown as follows: Figure 3 As shown, a user terminal accesses the satellite network and initiates a registration request. After receiving the user terminal's registration request, the signaling gateway sends an authentication request to the home location and, simultaneously, a welcome SMS instruction to the satellite SMS center. The SMS gateway caches the user's SMS message (at this point, the user terminal has not yet completed registration and session establishment). The remaining steps in the registration process are completed. The user terminal initiates a session establishment process and accesses the IMS (IP Multimedia Subsystem) network, establishing a path from the user terminal to the satellite, to the RAN (Radio Access Network), to the UPF (User Plane Function), and finally to the IMS. The SMS center then sends the welcome SMS message to the user terminal based on this path. The above method demonstrates that, in related art, sending the welcome SMS instruction to the satellite SMS center before the user terminal has completed registration and session establishment requires an excessively long buffering period.

[0041] Through the welcome SMS sending method of the embodiment of the present application, it is possible to obtain multiple time nodes in the process of a user terminal accessing a multimedia system; determine the target time for sending a trigger instruction to the SMS center based on the multiple time nodes, and the trigger instruction is used to trigger the SMS center to generate a welcome SMS; after the user terminal accesses the multimedia system, send indication information to the SMS center, and the indication information is used to instruct the SMS center to send a welcome SMS to the user terminal, and the target time is before the time when the user terminal accesses the multimedia system. By adjusting the time node for sending the trigger instruction to the SMS center, the purpose of shortening the cache time of the welcome SMS is achieved, thereby achieving the technical effect of improving the utilization rate of the storage resources of the SMS center, and thus solving the technical problem of low utilization rate of the storage resources of the SMS center due to the long waiting time for sending messages.

[0042] It should be noted that the time node in the embodiment of the present application may be the time point when all network elements perform actions in the process of the user terminal completing registration, establishing a session, accessing the IMS, and receiving a welcome SMS sent by the SMS center, for example: the time point when the signaling gateway receives the notification message that the user terminal completes registration, the time point when the signaling gateway receives the session establishment request from the user terminal, etc.

[0043] The above steps S202 to S206 are described in detail below through a specific embodiment.

[0044] In step S204, the target time for sending a trigger instruction to the SMS center is determined based on multiple time nodes. The specific method may be: receiving notification messages sent by multiple network elements, and determining the current time node among multiple time nodes in the process of the user terminal accessing the multimedia system based on the notification message; determining the target time for sending a trigger instruction to the SMS center based on the current time node, and the trigger instruction is used to instruct the SMS center to send a welcome SMS to the signaling gateway.

[0045] It should be noted that when the SMS center receives the trigger instruction, the user terminal has not yet accessed the IMS system. The SMS center needs to wait until the user terminal accesses the IMS system before sending a welcome SMS to the user terminal.

[0046] In an optional method, the target time for sending a trigger instruction to the SMS center can be determined based on the current time node. Specifically, the current time node is compared with the time nodes in the preset time node set to obtain a comparison result; when the comparison result indicates that the current time node belongs to the preset time node set, the current time node is determined to be the target time node, wherein the execution time of the time nodes in the preset time node set are all after the signaling gateway sends an authentication request to the unified data management function network element; the target time node is determined as the target time.

[0047] It should be noted that the preset time node set can be set according to actual conditions. It can be understood that the time points in the preset time node set are all after the user terminal completes registration.

[0048] In another optional manner, the target moment can be determined based on a preset moment, for example: when the current time node is a preset moment, the current time node is determined as the target moment, and the preset moment includes one of the following: the moment of receiving a first notification message sent by the first network element, the first notification message is used to indicate that the user terminal has completed registration and the moment of receiving the request message sent by the first network element, the moment of receiving the second notification message sent by the first network element for requesting the second network element to establish a target session, the moment of receiving the second notification message sent by the first network element, the second notification message is used to indicate that the target session has been established and the moment of receiving the third notification message sent by the second network element, the third notification message is used to indicate that the registration authentication of the user terminal has been completed and the fourth notification message sent by the second network element has been received, and the fourth notification message is used to return the authentication result of the target session establishment, wherein the first network element is an access and mobility management function network element in a satellite network, and the second network element is the home network of the user terminal.

[0049] It should be noted that the preset time includes at least: the moment when the signaling gateway receives the notification message of the completion of the user terminal registration, the moment when the signaling gateway receives the session establishment request of the user terminal, the moment when the signaling gateway receives the notification message of the completion of the session establishment of the user terminal, the moment when the signaling gateway receives the notification message of the completion of the authentication of the home UDM (user data management network element) (during the registration process), and the moment when the signaling gateway receives the authentication result for feedback of the session establishment request.

[0050] Figure 4a A flow chart of an optional method for sending a welcome SMS is shown in FIG. Figure 4a As shown, when the AMF sends a registration reception request to the user terminal, it notifies the signaling gateway that the user terminal registration is completed. The signaling gateway sends a trigger message to the SMS center to generate a welcome SMS.

[0051] It is understandable that triggering the SMS center to generate a welcome SMS after the user terminal registration is completed shortens the SMS center's SMS cache time and also avoids wasting cache resources due to user terminal registration failure.

[0052] UE stands for User Equipment; GW-C stands for Gateway Control, which is used to forward data; GW-U stands for User Plane Gateway, which works with GW-C to forward user data.

[0053] Figure 4b A flow chart of an optional method for sending a welcome SMS is shown in FIG. Figure 4b As shown in FIG, when the signaling gateway receives a request from the SMF (session management function network element) for session management data from the home network, the signaling gateway sends a trigger message to the SMS center.

[0054] In which, when there is a communication interface between the third network element in the satellite network and the signaling gateway, the time of receiving the fifth notification message sent by the third network element is determined as the preset time, wherein the third network element includes: a session management function network element in the satellite network.

[0055] It is understandable that the session management request can be sent by the SMF to the signaling gateway or by the AMF to the signaling gateway.

[0056] It should be noted that the time period for establishing the target session is obtained; any time point in the time period for establishing the target session is determined as the target moment. For example, AMF can notify the signaling gateway to send trigger information to the SMS center at any time when interacting with SMF during the session establishment process (determine any time when AMF and SMF interact during the session establishment process as the target moment).

[0057] Figure 4c A flow chart of an optional method for sending a welcome SMS is shown in FIG. Figure 4c As shown, when the session establishment completes the request, the AMF notifies the signaling gateway that the user terminal registration is complete, and the signaling gateway sends a trigger instruction to the SMS center.

[0058] Figure 4d A flow chart of an optional method for sending a welcome SMS is shown in FIG. Figure 4d As shown, during the registration process, when the signaling gateway receives the authentication information returned by the home network to the satellite network, the signaling gateway sends a prepare-to-send trigger instruction to the SMS center.

[0059] Figure 4e A flow chart of an optional method for sending a welcome SMS is shown in FIG. Figure 4e As shown, during the session establishment process, when the signaling gateway receives the authentication information returned by the home network to the satellite network, the signaling gateway is triggered to send a trigger instruction to the SMS center.

[0060] In some embodiments of the present application, the target time for sending the trigger instruction can also be determined by setting a timer. Specifically, when a registration request sent by a user terminal is received, the timer is started; when it is detected that the timer timing reaches the preset time, the trigger instruction is sent to the SMS center.

[0061] Figure 4f A flow chart of an optional method for sending a welcome SMS is shown in FIG. Figure 4f As shown, after the user terminal accesses the IMS, it can trigger an instruction to the SMS center within a preset period of time.
