Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a message broadcasting method, apparatus, device, medium, and program product. Background Technology

[0002] 5G messaging, as an upgrade to traditional SMS, boasts advantages such as strong user reach, native terminal access, lightweight interactive applications, and security and reliability. It supports sending rich media messages including text, images, audio, video, card messages, and multi-image / text messages, providing users with convenient one-stop services such as search, interaction, and payment within the messaging application. 5G messaging retains the native support and security of SMS terminals while adding multimedia capabilities, introducing new messaging modes like chatbots, and realizing "messaging as a service," significantly enhancing the channel value, entry point value, and ecosystem value of operator messaging.

[0003] However, based on the method of sending 5G emergency broadcast messages in related technologies, it is clear that it uses application-layer "pseudo-broadcast" technology. In reality, the 5G Message Center (5GMC) still needs to break the messages into individual 5G messages and send them to each user one by one; it is not a true broadcast technology. When emergency messages need to be sent to densely populated areas on a large scale in a short period of time, such as in the event of a major public safety incident like an earthquake, flood, or fire, it can easily cause wireless network congestion and paralysis of network equipment, including the message center. If a time-sharing or batch-based approach is adopted, the timely delivery of emergency information cannot be guaranteed, resulting in low efficiency in the transmission of emergency information.

[0144] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0145] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0146] In emergency scenarios involving public safety, such as natural disasters like earthquakes and floods, 5G messaging also supports sending emergency broadcast messages via the MaaP platform through application layer broadcasting.

[0147] The specific implementation is as follows: The emergency message sending platform connects to the MaaP platform of each region in the form of an emergency chatbot. Before sending a message, it needs to synchronize the user group information for emergency message delivery with the MaaP platform, specifying more than one recipient. Then, the message is sent to the 5GMC through the MaaP platform. The 5GMC calls the SMS modules of each province in the region in a polling manner to send the message. For SMS modules that are overloaded, hardware resources are used to handle the corresponding workload. If the hardware still cannot meet the demand, the next SMS module is called.

[0148] As can be seen from the above-mentioned method of sending 5G emergency broadcast messages, it uses application-layer "pseudo-broadcast" technology. In reality, it still needs to be split into individual 5G messages by 5GMC and sent to each user one by one. It is not a true broadcast technology.

[0149] Currently, there are abundant high-power, wide-coverage large tower resources available. Broadcast towers are used to provide universal services such as broadcasting and television. A single tower can typically transmit up to 1000W, with a maximum coverage range of nearly 100km. Compared to these large towers, base stations can be considered small towers. Meanwhile, 3GPP's 5G broadcast technology based on broadcast towers is also maturing, providing users with comprehensive information broadcasting services.

[0150] This application proposes a message broadcasting method, apparatus, device, medium, and program product to address the problem of low efficiency in transmitting emergency information.

[0151] See Figure 1 , Figure 1 This is one of the flowcharts of a message broadcasting method provided in the embodiments of this application, applied to a first platform, such as... Figure 1As shown, the method includes the following steps:

[0152] Step 101: Receive a message broadcast request sent by the second platform. The message broadcast request carries the message type and message data.

[0153] Specifically, the first platform mentioned above can be a network-side platform, specifically a 5G Messaging as a Platform (MaaP), and the second platform mentioned above can be a network-side platform, specifically an emergency chatbot platform.

[0154] The aforementioned message playback request can be used by a second platform to request message playback. The aforementioned message type can indicate whether the message to be played is an emergency message, and the message broadcasting method, such as broadcast or unicast. The aforementioned message data indicates the message data to be broadcast, that is, the payload of the broadcast message, which is the user data that needs to be actually transmitted to the terminal, and can include various forms of data such as text, images, audio, and video.

[0155] Step 102: Based on the message type, determine whether to send the message data to the terminal via a broadcast tower or a base station tower.

[0156] Specifically, the aforementioned broadcast towers can be used for the transmission of television and radio signals, providing universal services such as broadcasting and television. A single tower can typically transmit up to 1000W, with a maximum coverage area of ​​nearly 100km. The aforementioned base station towers can be used to refer to small base station antennas used in cellular mobile networks; relative to the broadcast towers, base stations can be called small towers. It is understood that the terminal can be a single terminal or multiple terminals.

[0157] For example, Figure 2 This is a schematic diagram of an end-to-end system architecture provided in an embodiment of this application, such as... Figure 2As shown, the equipment involved in this application embodiment mainly includes an emergency chatbot platform and a 5G messaging MaaP platform on the network side, core network related network elements (5GMC, Multimedia Broadcast and Multicast Service Function (MBSF), Multimedia Broadcast Single Frequency Network Transmission Function (MBSTF), Network Exposure Function (NEF), etc.), a 5G messaging software development kit (SDK) on the terminal side, and base station small towers and broadcast towers on the wireless side.

[0158] In this embodiment, the above-mentioned message broadcasting method is applied to a first platform. It can receive a message broadcasting request sent by a second platform. The message broadcasting request carries a message type and message data. Based on the message type, it determines whether to send the message data to the terminal via a broadcast tower or a base station tower. This allows different broadcasting methods to be selected according to different message types. Broadcasting can be performed based on both broadcast towers and base station towers, thereby improving the efficiency of emergency message transmission in different scenarios.

[0159] Optionally, determining whether to send the message data to the terminal via a broadcast tower or a base station tower based on the message type includes:

[0160] In the case where the message type is 5G New Radio NR Broadcast Message, a broadcast message broadcast creation request is sent to the first network element;

[0161] Receive the creation success response sent by the first network element;

[0162] Send an application service announcement to the terminal.

[0163] Specifically, the aforementioned first network element can be NEF, primarily used for format conversion of emergency broadcast messages and identification as 5G emergency broadcast messages. The aforementioned application service announcement can be used to notify the terminal to receive 5G NR broadcast messages, and may specifically include time and frequency information, etc.

[0164] In this embodiment, the above-mentioned message broadcasting method can send a broadcast message broadcasting creation request to the first network element when the message type is a 5G new wireless NR broadcast message, receive a creation success response from the first network element, and send an application service announcement to the terminal. This allows the application service announcement to be sent to the terminal when the emergency broadcast message broadcasting creation success response is received, so that the terminal can receive the emergency broadcast 5G message according to the time and frequency information specified in the application service announcement, thereby improving the accuracy of the terminal receiving the emergency broadcast 5G message.

[0165] Optionally, the broadcast message creation request carries at least one of the following:

[0166] The message data, Multimedia Broadcast Service Area (MBS), group message transmission start time, and group message transmission stop time.

[0167] Specifically, the aforementioned Multimedia Broadcast Service Area (MBS) can indicate the geographical coverage of a broadcast or multicast service, the aforementioned group message transmission start time can indicate the start time of the scheduled transmission of a broadcast message, and the aforementioned group message transmission stop time can indicate the end time of the transmission of a broadcast message.

[0168] In this embodiment, the broadcast message creation request carrying the MBS service area can ensure that the message transmission target is clear. The broadcast message creation request carrying the group message transmission start time helps to start message transmission on time and ensure that the broadcast content is sent at the appropriate time. The broadcast message creation request carrying the group message transmission stop time helps to manage resources and prevent unnecessary message transmission.

[0169] Optionally, the method further includes:

[0170] Receive the broadcast message broadcast status sent by the first network element, wherein the broadcast message broadcast status is used to indicate that the broadcast message was successfully broadcast;

[0171] Send the broadcast message broadcast status to the second platform.

[0172] In this embodiment, the method receives the broadcast message broadcast status sent by the first network element, which indicates that the broadcast message was successfully broadcast, and sends the broadcast message broadcast status to the second platform, so that the second platform can promptly know the broadcast message broadcast status and determine whether the broadcast message was successfully broadcast, thereby improving the accuracy of broadcast message broadcasting.

[0173] For example, Figure 3This is one of the interactive flowcharts of a message broadcasting method provided in an embodiment of this application, such as... Figure 3 As shown, Figure 3 In this context, the 5G messaging MaaP platform is the first platform, the emergency Chatbot platform is the second platform, NEF is the first network element, MBSTF is the second network element, and MBSF is the third network element. The message broadcasting method includes the following interaction process:

[0174] 1. The emergency chatbot platform initiates an emergency broadcast message broadcasting request to the 5G messaging MaaP platform;

[0175] 2. The 5G Messaging MaaP platform determines that the emergency message type in the API is "5G NR Broadcast" emergency message and sends a request message to NEF. The request message includes the group message payload, Multimedia Broadcast Service Area (MBS), group message transmission start time, stop time, etc.

[0176] 3. NEF converts the group message payload into a file and assigns a group message-related ID to identify the group message delivery request;

[0177] 4-8. If the application service configuration has not yet been executed, then execute the application service configuration process for the relevant network elements in steps 4 to 8; otherwise, the application service configuration can be skipped.

[0178] 9. NEF sends an emergency broadcast to the MaaP platform to announce the successful creation response (including group message related ID, acceptance status, etc.);

[0179] 10. The MaaP platform sends application service announcements to the terminal UE;

[0180] 11. NEF performs the user data push process to MBSTF. NEF can push files to MBSTF, and MBSTF can also extract files from NEF.

[0181] 12. MBSTF performs packetization and FEC encoding;

[0182] 13. MBSTF transmits the packetized data to the UE via the broadcast tower;

[0183] 14. Based on the time and frequency information corresponding to the service announcement information received in step 10, the terminal receives data packets, performs FEC decoding to recover the file, and obtains group messages from the file. The 5G message SDK built into the terminal parses and displays the group messages according to the 5G message format.

[0184] 15-17. MBSTF notifies MBSF of the user data distribution status, then MBSF notifies NEF of the user data push status, and NEF then informs the emergency chatbot platform of the emergency message broadcast result through the MaaP platform.

[0185] Optionally, determining whether to send the message data to the terminal via a broadcast tower or a base station tower based on the message type includes:

[0186] In the case where the message type is a unicast message or a pseudo-broadcast message, the message data is sent to the 5G Message Center (5GMC) corresponding to the terminal according to the terminal address in the message broadcast request, so as to send the message data to the terminal through the base station small tower.

[0187] Specifically, the aforementioned terminal address can be used to indicate the recipient address, and can include two types: a recipient list and a recipient pointer. The recipient list is a specific group of recipient users, and the recipient pointer is used to point to the address of a data structure that stores recipient information.

[0188] For example, taking the case where the message type is a pseudo-broadcast message as an example, Figure 4 This is the second interactive flowchart of a message broadcasting method provided in the embodiments of this application, as follows: Figure 4 As shown, Figure 4 The MaaP platform is the first platform, and the emergency Chatbot platform is the second platform. The message broadcasting method includes the following interaction flow:

[0189] First, the emergency chatbot platform calls the message application programming interface (API) provided by the MaaP platform to send a message to the MaaP platform. The message contains a list of recipients (as shown in this process). Figure 4 In this context, the recipients are either A, B, and C) or a recipient pointer (such as a pointer to a file that records the numbers of all Beijing Mobile users).

[0190] Then, the MaaP platform parses the recipient list (as in this process). Figure 4 In the process, the receivers (including A, B, and C) or pointers are parsed out (e.g., parsing the pointer "all Beijing Mobile users" will parse out the mobile phone numbers of all Beijing Mobile users from the database), and the message server API is called to send the message to the 5GMC to which the receiver user belongs. The message carries the list of receiving users in that 5GMC or pointer.

[0191] Secondly, the message server parses the list or pointer of recipients to determine the recipient user;

[0192] Finally, following the normal A2P message delivery steps and message format, 5GMC sends the Chatbot message to all users who need to receive it via the base station tower.

[0193] It is understandable that when the message type is a unicast message, the recipient address corresponds to a single terminal. The MaaP platform parses the message to obtain a single recipient and calls the message server API to send the message to the 5GMC to which the recipient user belongs.

[0194] Optionally, the message types include emergency messages and non-emergency messages, and the emergency messages include at least one of unicast messages, pseudo-broadcast messages, and 5G NR broadcast messages.

[0195] Specifically, the aforementioned emergency messages refer to messages sent in emergency situations. These messages typically contain crucial information and need to be quickly delivered to specific audiences to ensure their safety or to inform them of an emergency. In contrast, the aforementioned non-emergency messages are general information deliveries that do not involve immediate security threats or emergency situations.

[0196] Understandably, the second platform's message API can categorize emergency messages into three types based on their broadcasting methods. The first type is unicast emergency messages, which are ordinary 5G messages targeted at a single user and broadcast via the unicast link of the base station's small tower. The second type is "pseudo-broadcast" emergency messages, which are ordinary 5G messages targeted at multiple users and broadcast via the unicast link of the base station's small tower. The third type is "5G NR broadcast" emergency messages, which are messages based on 5G NR broadcasting and broadcast via the broadcast link of the broadcast tower.

[0197] For example, the API definitions related to emergency broadcast messages in the API for interaction between the second platform and the first platform can be referenced as follows:
