[0197] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments made by those of ordinary skill in the art according to the inspiration of the present embodiments belong to the scope of protection of the present application.

[0198] The terms "first", "second", "third", "fourth" and the like (if any) in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product or device.

[0199] With the development of science and technology, before natural disasters such as earthquakes, typhoons and floods, people can be reminded that disasters are coming through early warning, and people can take appropriate avoidance methods to improve personal and property safety.

[0200] In the prior art, for disaster warning, a public warning system (PWS) is usually used to achieve it. The public warning system includes a server, a base station and a user equipment, the server sends warning information to the base station, the base station adds the warning information into a system message, and then broadcasts the system message, and the user equipment can receive the system message. However, due to the design of the system message itself, only text information can be added in the system message, so in the case of needing to use audio and video to prompt users about disaster conditions, and using pictures to display escape route indications, so that users can more clearly understand the situation of the danger, that is, in the case of needing to transmit multimedia information, multimedia information cannot be added in the system message, and multimedia information cannot be transmitted.

[0201] In view of the problems in the prior art, the inventors have found, in the process of researching the disaster warning method, that for broadcast transmission of multimedia information, broadcast radio bearer can realize this function, so that the transmission of multimedia information can be realized by establishing a broadcast radio bearer between the user equipment and the base station. However, for the successful establishment of the broadcast radio bearer, the warning server needs to issue a warning message to the core network device, the core network device and the base station establish a broadcast session, and then the base station sends broadcast radio bearer configuration data to the user terminal, so that the user terminal can establish a broadcast radio bearer with the base station. Based on the above invention concept, the disaster warning scheme in the present application is designed.

[0202] The application scenario of the disaster warning method provided in the present application is illustrated below.

[0203] For example, in this application scenario, a typhoon is approaching the A area, and multimedia information needs to be broadcast to the user equipment in the A area, including video, audio, and pictures about measures to prevent the typhoon. The warning server receives a warning instruction, and the warning server generates a first warning message, which includes a communication type indicating broadcast communication, a base station list, a cell list corresponding to each base station in the base station list, a warning information sending start time, a warning information repeated sending period, and a warning information repeated sending number of times. The base stations in the base station list are the base stations in the A area.

[0204] The core network device determines that the communication type indicates broadcast communication, and sends a broadcast session establishment request corresponding to each base station in the base station list to the base station, which includes a cell list corresponding to the base station, a warning information sending start time, a warning information repeated sending period, and a warning information repeated sending number of times.

[0205] After the base station establishes a broadcast session with the core network device, the base station sends broadcast radio bearer configuration data to each user equipment in each cell in the cell list according to the warning information sending start time, the warning information repeated sending period, and the warning information repeated sending number of times.

[0206] The user equipment establishes a broadcast radio bearer with the base station according to the broadcast radio bearer configuration data.

[0207] Then, the warning server sends multimedia information parsing data to the user equipment through the core network device and the base station.

[0208] ​​​​​​​The early warning server sends the initial early warning multimedia information to the core network device according to the early warning information sending starting moment, early warning information repeated sending period and early warning information repeated sending number. The core network device sends the initial early warning multimedia information to the base station through a broadcast session with the base station. The base station sends the initial early warning multimedia information to the user equipment through a broadcast radio bearer with the user equipment. The user equipment parses the initial early warning multimedia information according to multimedia information parsing data to obtain the target early warning multimedia information.

[0209] The target early warning multimedia information includes video, audio and pictures about typhoon prevention measures. After the user terminal outputs the early warning multimedia information, the user can obtain the target early warning multimedia information and take prevention measures to prevent the typhoon in advance, thereby improving the user's life and property safety.

[0210] It should be noted that the above scenario is only an example of an application scenario provided by the embodiments of the present application, and the actual form of various devices included in the scenario is not limited in the embodiments of the present application. In the specific application of the scheme, it can be set according to the actual needs.

[0211] In the following, the technical scheme of the present application is described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0212] Figure 1 The flowchart of the disaster early warning method embodiment provided by the present application is shown in the figure, and the embodiments of the present application explain the establishment of the broadcast session between the core network device and the base station, the establishment of the broadcast radio bearer between the base station and the user equipment, the sending of the initial early warning multimedia information from the early warning server to the core network, and then the sending to the user equipment through the broadcast session and the broadcast radio bearer, so as to realize the broadcast transmission of the multimedia information. The method in the embodiment can be realized by software, hardware or combination of software and hardware. As shown in the figure, the disaster early warning method specifically includes the following steps: Figure 1

[0213] S101: The early warning server sends a first early warning message to the core network device.

[0214] In this step, the early warning server monitors the arrival of the disaster, and sends a first early warning message to the core network device. The first early warning message includes a communication type indicating broadcast communication, a base station list, a cell list corresponding to each base station in the base station list, an early warning information sending starting moment, an early warning information repeated sending period and an early warning information repeated sending number.

[0215] ​It should be noted that the starting moment of the early warning information sending is a moment before the disaster sending moment by a first preset time length. The first preset time length can be 30 seconds, 1 minute, 10 minutes, 3 hours, 5 hours, etc. The embodiment of the application does not limit the first preset time length, which can be set according to actual conditions.

[0216] It should be noted that the early warning information repeated sending period can be 3 seconds, 2 minutes, 10 minutes, 1 hour, etc. The early warning information repeated sending number can be 3 times, 5 times, 10 times, etc. The embodiment of the application does not limit the early warning information repeated sending period and the early warning information repeated sending number, which can be determined according to actual conditions.

[0217] It should be noted that the first early warning message can also include a message name, an early warning type, etc. The embodiment of the application does not limit the content included in the first early warning message, which can be set according to actual conditions.

[0218] It should be noted that the way in which the early warning server monitors the arrival of the disaster can be that the first early warning message sent by the third party platform is received. It can also be that the first early warning message input by the user is obtained. It can also be that the first early warning message is obtained from the third party platform. The embodiment of the application does not limit the way in which the early warning server monitors the arrival of the disaster, which can be determined according to actual conditions.

[0219] S102: After the core network device receives the first early warning message sent by the early warning server, if the communication type indicates broadcast communication, the core network device sends a broadcast session establishment request corresponding to each base station in the base station list to each base station.

[0220] In this step, after the early warning server sends the first early warning message to the core network device, the core network device can receive the first early warning message, and then determine the communication mode according to the communication type therein. Since the communication type in the first early warning message indicates broadcast communication, the communication mode is broadcast communication.

[0221] Further, the broadcast session establishment request corresponding to each base station in the base station list is sent to each base station. The broadcast session establishment request corresponding to each base station includes the early warning information sending starting moment, the early warning information repeated sending period, the early warning information repeated sending number, and the cell list corresponding to the base station.

[0222] It should be noted that the communication type includes a communication type indicating broadcast communication, groupcast communication, and unicast communication.

[0223] S103: After the base station receives the broadcast session establishment request sent by the core network device, if the current service rate is less than a preset service rate threshold, the base station establishes a broadcast session with the core network device.

[0224] In this step, after the core network device sends the broadcast session establishment request to the base station, the base station can receive the broadcast session establishment request, and then determine whether the broadcast session can be established according to the size of the current service rate of the base station.

[0225] If the base station determines that the current service rate is less than the preset service rate threshold, it means that the current network load of the base station is small, and the base station establishes the broadcast session with the core network device.

[0226] It should be noted that if the base station determines that the current service rate is greater than or equal to the preset service rate threshold, it means that the current network load of the base station is large, and the base station does not establish the broadcast session with the core network device.

[0227] It should be noted that the preset service rate threshold can be 10 Mbps, 100 Mbps, 500 Mbps, etc. The preset service rate threshold is not limited in the embodiments of the present application, and can be set according to actual conditions.

[0228] S104: The base station sends the broadcast radio bearer configuration data to each user equipment in each cell in the cell list according to the warning information sending start time, the warning information repeated sending period, and the warning information repeated sending number of times.

[0229] In this step, after the base station establishes the broadcast session with the core network device, in order to be able to transmit multimedia information subsequently, the base station needs to send the broadcast radio bearer configuration data to each user equipment in each cell in the cell list according to the warning information sending start time, the warning information repeated sending period, and the warning information repeated sending number of times. So that the user equipment can establish the broadcast radio bearer with the base station subsequently to transmit the multimedia information.

[0230] Specifically, since the subsequent warning server will start sending the initial warning multimedia information at the warning information sending start time, and send it once every warning information repeated sending period, a total of warning information repeated sending number of times, in order to enable the initial warning multimedia information to be transmitted to the base station, the base station can send it to the user equipment through the broadcast radio bearer, the base station needs to start sending the broadcast radio bearer configuration data at a time point that is a second preset time length before the warning information sending start time, and send it once every warning information repeated sending period, a total of warning information repeated sending number of times. So that the user equipment can establish the broadcast radio bearer with the base station in advance.

[0231] It should be noted that the second preset time length can be 50 milliseconds, 100 milliseconds, 1 second, 3 seconds, etc. The second preset time length is not limited in the embodiments of the present application, and can be set according to actual conditions.

[0232] For example, the starting time of the early warning information sending is 10:20:30, the second preset time length is 1 second, the early warning information repeating sending period is 1 minute, and the early warning information repeating sending number is 3 times. Then, the base station starts to send the broadcast radio bearer configuration data at 10:20:29, and sends the broadcast radio bearer configuration data every 1 minute, for a total of 3 times. That is, the broadcast radio bearer configuration data is sent at 10:20:29, 10:21:29, and 10:22:29, respectively.

[0233] S105: After the user equipment receives the broadcast radio bearer configuration data sent by the base station, the broadcast radio bearer of the base station is established according to the broadcast radio bearer configuration data.

[0234] In this step, after the base station sends the broadcast radio bearer configuration data to the user equipment, the broadcast radio bearer of the base station is established according to the broadcast radio bearer configuration data.

[0235] Since the base station will send the broadcast radio bearer configuration data to the user equipment at least once, the user equipment will establish the broadcast radio bearer of the base station every time the base station sends the broadcast radio bearer configuration data. Then, every time the initial early warning multimedia information is received through the broadcast radio bearer, the broadcast radio bearer is released, thereby saving network resources.

[0236] S106: The early warning server sends the multimedia information analysis data to the core network device.

[0237] In this step, after the early warning server sends the first early warning message to the core network device, the early warning server sends the multimedia information analysis data to the core network device at a third preset time length, so that the core network device sends the multimedia information analysis data to the user equipment through the base station, and the user equipment uses the multimedia information analysis data to analyze the initial early warning multimedia information.

[0238] The reason why the early warning server is at a third preset time length between the sending time of the first early warning message and the sending time of the multimedia information analysis data is that the broadcast session establishment of the core network device and the base station is guaranteed.

[0239] It should be noted that the third preset time length can be 50 milliseconds, 100 milliseconds, 1 second, 3 seconds, etc., and the third preset time length is not limited in the embodiment of the application and can be set according to actual conditions.

[0240] It should be noted that the time at which the early warning server sends the multimedia information analysis data is earlier than the early warning information sending starting time.

[0241] It should be noted that the multimedia information parsing data can carry a message name, a session type, a priority, etc. The embodiments of the present application do not limit the data carried by the multimedia information parsing data, and the data can be set according to actual conditions.

[0242] S107: After the core network device receives the multimedia information parsing data sent by the early warning server, for each base station in the base station list, the core network device sends the multimedia information parsing data to the base station through a broadcast session with the base station.

[0243] In this step, after the early warning server sends the multimedia information parsing data to the core network device, the core network device can receive the multimedia information parsing data. In order for the user equipment to be able to receive the multimedia information parsing data, for each base station in the base station list, the core network device sends the multimedia information parsing data to the base station through a broadcast session with the base station.

[0244] S108: After the base station receives the multimedia information parsing data sent by the core network device through a broadcast session with the core network device, for each user equipment in each cell in the cell list, the base station sends the multimedia information parsing data to the user equipment through a broadcast radio bearer with the user equipment.

[0245] In this step, after the core network device sends the multimedia information parsing data to the base station, the base station can receive the multimedia information parsing data through a broadcast session with the core network device, and then for each user equipment in each cell in the cell list, the base station sends the multimedia information parsing data to the user equipment through a broadcast radio bearer with the user equipment.

[0246] S109: The user equipment receives the multimedia information parsing data sent by the base station through a broadcast radio bearer with the base station.

[0247] In this step, after the base station sends the multimedia information parsing data to the user equipment, the user equipment can receive the multimedia information parsing data through a broadcast radio bearer with the base station.

[0248] S110: The early warning server sends initial early warning multimedia information to the core network device according to a start time of early warning information sending, a repetition sending period of early warning information, and a repetition sending number of early warning information.

[0249] In this step, after the early warning server sends the multimedia information parsing data, the early warning server starts to send the initial early warning multimedia information at the start time of early warning information sending, and sends the initial early warning multimedia information once every repetition sending period of early warning information, and a total of repetition sending number of early warning information times.

[0250] For example, the initial warning multimedia information sending starting time is 10:20:30, the warning information repeating sending period is 1 minute, and the warning information repeating sending times are 3 times. The warning server starts to send the initial warning multimedia information at 10:20:30, and sends the initial warning multimedia information every 1 minute, totally 3 times. That is, the initial warning multimedia information is sent at 10:20:30, 10:21:30 and 10:22:30 respectively.

[0251] It should be noted that the initial warning multimedia information can include a warning type, and the warning type is earthquake, tsunami, typhoon, flood, etc.

[0252] S111: After the core network device receives the initial warning multimedia information sent by the warning server, the core network device sends the initial warning multimedia information to each base station in the base station list through a broadcast session with the base station.

[0253] In this step, after the warning server sends the initial warning multimedia information to the core network device each time, the core network device can receive the initial warning multimedia information, and then sends the initial warning multimedia information to each user equipment in each cell in the cell list through a broadcast wireless bearer with the user equipment.

[0254] S112: After the base station receives the initial warning multimedia information sent by the core network device through a broadcast session with the core network device, the base station sends the initial warning multimedia information to each user equipment in each cell in the cell list through a broadcast wireless bearer with the user equipment.

[0255] In this step, after the core network device sends the initial warning multimedia information to the base station each time, the base station can receive the initial warning multimedia information through a broadcast session with the core network device. Since the broadcast wireless bearer between the base station and the user equipment has been established when the initial warning multimedia information is received each time, the base station sends the initial warning multimedia information to each user equipment in each cell in the cell list through a broadcast wireless bearer with the user equipment.

[0256] S113: After the user equipment receives the initial warning multimedia information sent by the base station through a broadcast wireless bearer with the base station, the user equipment parses the initial warning multimedia information according to multimedia information parsing data to obtain target warning multimedia information.

[0257] In this step, after the base station sends the initial warning multimedia information to the user equipment each time, the user equipment can receive the initial warning multimedia information through a broadcast wireless bearer with the base station. Then, the user equipment parses the initial warning multimedia information according to multimedia information parsing data to obtain target warning multimedia information.

[0258] Since the initial early warning multimedia information is information with a specific format, it needs to be parsed using multimedia information parsing data, so that the target early warning multimedia information that can be output is obtained.

[0259] The subsequent user equipment outputs the target early warning multimedia information. When the target early warning multimedia information is a picture or text, the target early warning multimedia information can be displayed. When the target early warning multimedia information is audio, the target early warning multimedia information can be played. When the target early warning multimedia information is a video, the target early warning multimedia information can be displayed and played. In this way, the user can learn the target early warning multimedia information, prevent disasters, and improve the safety of the user's life and property.

[0260] It should be noted that steps S101-S105 are implemented through a network layer, and steps S106-S109 and steps S110-S113 are implemented through an application layer. The network layer and the application layer correspond to different transmission interfaces and transmission modules, and therefore, the early warning server sends the first early warning message and the multimedia information parsing data separately.

[0261] The disaster early warning method provided in this embodiment sends a first early warning message to a core network device through an early warning server. The core network device broadcasts a communication type according to an indication in the first early warning message, and sends a broadcast session establishment request to a base station. After the base station establishes a broadcast session with the core network device, the base station sends broadcast radio bearer configuration data to a user equipment. The user equipment establishes a broadcast radio bearer with the base station according to the broadcast radio bearer configuration data. Then, the early warning server, the core network device, and the base station send multimedia information parsing data and initial early warning multimedia information to the user equipment through the broadcast session and the broadcast radio bearer. The user equipment parses the initial early warning multimedia information according to the multimedia information parsing data to obtain target early warning multimedia information. This scheme establishes a broadcast session through the core network device and the base station, and establishes a broadcast radio bearer through the base station and the user equipment, thereby realizing the transmission of multimedia information.

[0262] Figure 2 The flowchart of the second embodiment of the disaster early warning method provided in this application is based on the first embodiment, and this embodiment describes the case where the base station sends a first response message to the early warning server through the core network device. As shown in Figure 2 The disaster early warning method specifically includes the following steps:

[0263] S201: After receiving the broadcast session establishment request sent by the core network device, the base station generates a broadcast session establishment result according to whether the current service rate is less than a preset service rate threshold.

[0264] In this step, after the core network device sends the broadcast session establishment request to the base station, the base station can receive the broadcast session establishment request, and then determine whether the broadcast session can be established with the core network device according to whether the current service rate is less than the preset service rate threshold, and generate a broadcast session establishment result. The broadcast session establishment result indicates that the broadcast session establishment is successful or failed.

[0265] Specifically, if the current service rate is less than the preset service rate threshold, a broadcast session establishment result indicating that the broadcast session establishment is successful is generated; if the current service rate is greater than or equal to the preset service rate threshold, a broadcast session establishment result indicating that the broadcast session establishment is failed is generated.

[0266] S202: The base station sends a first response message to the core network device.

[0267] In this step, after the base station generates the broadcast session establishment result, the base station sends a first response message to the core network device, so that the core network device knows which base stations establish the broadcast session with the core network device and which base stations do not establish the broadcast session with the core network device. The first response message includes the broadcast session establishment result and the base station identifier of the base station.

[0268] It should be noted that the first response message also includes message name, session identifier, session description information, etc. The embodiments of the present application do not limit the content included in the first response message, which can be set according to actual conditions.

[0269] S203: After the core network device receives the first response message sent by the base station, the core network device sends the first response message to the early warning server.

[0270] In this step, after the base station sends the first response message to the core network device, the core network device can receive the first response message, and then in order for the early warning server to know which base stations establish the broadcast session with the core network device and which base stations do not establish the broadcast session with the core network device, the core network device needs to send the first response message to the early warning server.

[0271] It should be noted that if the broadcast session establishment result in the received first response message indicates that the broadcast session establishment is failed, the core network device can resend the broadcast session establishment request to the base station.

[0272] S204: The early warning server receives the first response message sent by the core network device.

[0273] In this step, after the core network device sends the first response message to the early warning server, the early warning server can receive the first response message. Subsequently, the early warning server can output the first response message, so that the worker can check the base stations that do not establish the broadcast session with the core network device for maintenance.

[0274] The disaster early warning method provided in the embodiment sends a first response message to the core network device through the base station, so that the core network device re-sends a broadcast session establishment request to the base station that has not established a broadcast session with the core network device, thereby improving the success rate of establishment of the broadcast session. The core network device sends the first response message to the early warning server, so that the staff member repairs the base station that has not established a broadcast session with the core network device, thereby ensuring normal operation of the base station.

[0275] Figure 3 The flowchart of the third embodiment of the disaster early warning method provided in the application, the embodiment of the application describes the establishment of a multicast session by the core network device and the base station, the establishment of a multicast radio bearer by the base station and the user equipment, the sending of initial early warning multimedia information by the early warning server to the core network, and the sending of the initial early warning multimedia information to the user equipment through the multicast session and the multicast radio bearer, thereby realizing multicast transmission of the multimedia information. As shown in Figure 3 The disaster early warning method specifically includes the following steps:

[0276] S301: The early warning server sends a second early warning message to the core network device.

[0277] After the disaster occurs, the user equipment of the rescue personnel can be sent multimedia information in a multicast transmission mode, so that the rescue personnel can quickly launch rescue actions.

[0278] In this step, the early warning server sends a second early warning message to the core network device. The second early warning message includes a communication type indicating multicast communication, a base station list, a cell list corresponding to each base station in the base station list, a group list corresponding to each cell in each cell list, a starting time of early warning information sending, a repetition sending period of early warning information, and a repetition sending number of early warning information.

[0279] It should be noted that the second early warning message can also include a message name and a warning type, and the embodiment of the application does not limit the content included in the second early warning message, which can be set according to actual conditions.

[0280] It should be noted that the starting time of early warning information sending in this embodiment is a time set by the staff member according to the development of the disaster, which can be any time of the day, and the embodiment of the application does not limit the starting time of early warning information sending, which can be set according to actual conditions.

[0281] It should be noted that the way of triggering the early warning server to send the second early warning message to the core network device can be: receiving a second early warning message sent by a third-party platform. It can also be: obtaining a second early warning message input by a user. It can also be: obtaining a second early warning message from a third-party platform. The embodiment of the application does not limit the way of triggering the early warning server to send the second early warning message to the core network device, which can be determined according to actual conditions.

[0282] S302: After the core network device receives the second early warning message sent by the early warning server, if the communication type indicates multicast communication, the core network device sends a multicast session establishment request corresponding to each base station in the base station list to each base station.

[0283] In this step, after the early warning server sends the second early warning message to the core network device, the core network device can receive the second early warning message, and determine the communication mode according to the communication type in the second early warning message. Since the communication type in the second early warning message indicates multicast communication, the communication mode is multicast communication.

[0284] Then, the core network device sends a multicast session establishment request corresponding to each base station in the base station list to each base station. The multicast session establishment request corresponding to each base station includes a cell list corresponding to the base station, a group list corresponding to each cell in each cell list, a starting time of early warning information sending, a repetition sending period of early warning information, and a repetition sending number of early warning information.

[0285] S303: After the base station receives the multicast session establishment request sent by the core network device, if the current service rate is less than the preset service rate threshold, the base station establishes a multicast session with the core network device.

[0286] In this step, after the core network device sends the multicast session establishment request to the base station, the base station can receive the multicast session establishment request, and then determine whether to establish a multicast session according to the size of the current service rate of the base station.

[0287] If the base station determines that the current service rate is less than the preset service rate threshold, it means that the current network load of the base station is small, and then the base station establishes a multicast session with the core network device.

[0288] It should be noted that if the base station determines that the current service rate is greater than or equal to the preset service rate threshold, it means that the current network load of the base station is large, and then the base station does not establish a multicast session with the core network device.

[0289] S304: The base station sends multicast radio bearer configuration data to each user equipment in the group list corresponding to each cell in the cell list according to the starting time of early warning information sending, the repetition sending period of early warning information, and the repetition sending number of early warning information.

[0290] In this step, after the base station establishes a multicast session with the core network device, in order to transmit multimedia information subsequently, the base station needs to send multicast radio bearer configuration data to each user equipment in the group list corresponding to each cell in the cell list according to the starting time of early warning information sending, the repetition sending period of early warning information, and the repetition sending number of early warning information. So that the user equipment can establish a multicast radio bearer with the base station to transmit multimedia information.

[0291] Specifically, since the subsequent early warning server starts to send the initial early warning multimedia information at the early warning information sending starting moment, and sends it once every early warning information repeated sending period, a total of early warning information repeated sending times, in order to make the initial early warning multimedia information when transmitted to the base station, the base station can send it to the user equipment through the multicast radio bearer, the base station needs to start sending the multicast radio bearer configuration data at the moment of the second preset time length before the early warning information sending starting moment, and sends it once every early warning information repeated sending period, a total of early warning information repeated sending times. So that the subsequent user equipment can establish the multicast radio bearer with the base station in advance.

[0292] S305: After the user equipment receives the multicast radio bearer configuration data sent by the base station, the multicast radio bearer configuration data is established with the base station according to the multicast radio bearer configuration data.

[0293] In this step, after the base station sends the multicast radio bearer configuration data to the user equipment, the multicast radio bearer configuration data is established with the base station according to the multicast radio bearer configuration data.

[0294] Since the base station will send at least once multicast radio bearer configuration data to the user equipment, the user equipment will establish the multicast radio bearer with the base station every time the base station sends the multicast radio bearer configuration data, and then release the multicast radio bearer after receiving the initial early warning multimedia information through the multicast radio bearer every time, saving network resources.

[0295] S306: The early warning server sends the multimedia information analysis data to the core network device.

[0296] In this step, after the early warning server sends the second early warning message to the core network device, it will send the multimedia information analysis data to the core network device at intervals of a third preset time length, so that the core network device sends the multimedia information analysis data to the user equipment through the base station, and the user equipment uses the multimedia information analysis data to analyze the initial early warning multimedia information.

[0297] The reason why the early warning server is interval of a third preset time length between the sending moment of the second early warning message and the sending moment of the multimedia information analysis data: to ensure that the multicast session establishment of the core network device and the base station is completed.

[0298] It should be noted that the third preset time length can be 50 milliseconds, 100 milliseconds, 1 second, 3 seconds, etc., and the third preset time length is not limited by the present application. It can be set according to the actual situation.

[0299] It should be noted that the moment when the early warning server sends the multimedia information analysis data is earlier than the early warning information sending starting moment.

[0300] It should be noted that the multimedia information analysis data can carry message name, session type, priority, etc. The embodiments of the present application do not limit the data carried by the multimedia information analysis data, and the data can be set according to actual conditions.

[0301] S307: After the core network device receives the multimedia information analysis data sent by the early warning server, the core network device sends the multimedia information analysis data to each base station in the base station list through a multicast session with the base station.

[0302] In this step, after the early warning server sends the multimedia information analysis data to the core network device, the core network device can receive the multimedia information analysis data. In order for the user equipment to be able to receive the multimedia information analysis data, the core network device sends the multimedia information analysis data to each user equipment in the group list corresponding to each cell in the cell list through a multicast session with the user equipment.

[0303] S308: After the base station receives the multimedia information analysis data sent by the core network device through a multicast session with the core network device, the base station sends the multimedia information analysis data to each user equipment in the group list corresponding to each cell in the cell list through a multicast radio bearer with the user equipment.

[0304] In this step, after the core network device sends the multimedia information analysis data to the base station, the base station can receive the multimedia information analysis data through a multicast session with the core network device, and then send the multimedia information analysis data to each user equipment in the group list corresponding to each cell in the cell list through a multicast radio bearer with the user equipment.

[0305] S309: The user equipment receives the multimedia information analysis data sent by the base station through a multicast radio bearer with the base station.

[0306] In this step, after the base station sends the multimedia information analysis data to the user equipment, the user equipment can receive the multimedia information analysis data through a multicast radio bearer with the base station.

[0307] S310: The early warning server sends initial early warning multimedia information to the core network device according to the early warning information sending start time, the early warning information repeated sending period, and the early warning information repeated sending number.

[0308] In this step, after the early warning server sends the multimedia information analysis data, the early warning server starts to send initial early warning multimedia information at the early warning information sending start time, and sends it once every early warning information repeated sending period, a total of early warning information repeated sending number of times.

[0309] It should be noted that the initial warning multimedia information can include a warning type, and the warning type is an earthquake, a tsunami, a typhoon, a flood, etc.

[0310] S311: After the core network device receives the initial warning multimedia information sent by the warning server, for each base station in the base station list, the core network device sends the initial warning multimedia information to the base station through a multicast session with the base station.

[0311] In this step, after the warning server sends the initial warning multimedia information to the core network device each time, the core network device can receive the initial warning multimedia information, and then for each user equipment in the group list corresponding to each cell in the cell list, the core network device sends the initial warning multimedia information to the user equipment through a multicast wireless bearer with the user equipment.

[0312] S312: After the base station receives the initial warning multimedia information sent by the core network device through a multicast session with the core network device, for each user equipment in the group list corresponding to each cell in the cell list, the base station sends the initial warning multimedia information to the user equipment through a multicast wireless bearer with the user equipment.

[0313] In this step, after the core network device sends the initial warning multimedia information to the base station each time, the base station can receive the initial warning multimedia information through a multicast session with the core network device. Since the multicast wireless bearer between the base station and the user equipment has been established when the initial warning multimedia information is received each time, for each user equipment in the group list corresponding to each cell in the cell list, the base station sends the initial warning multimedia information to the user equipment through a multicast wireless bearer with the user equipment.

[0314] S313: After the user equipment receives the initial warning multimedia information sent by the base station through a multicast wireless bearer with the base station, the user equipment parses the initial warning multimedia information according to multimedia information parsing data to obtain target warning multimedia information.

[0315] In this step, after the base station sends the initial warning multimedia information to the user equipment each time, the user equipment can receive the initial warning multimedia information through a multicast wireless bearer with the base station, and then parse the initial warning multimedia information according to multimedia information parsing data to obtain target warning multimedia information.

[0316] Since the initial warning multimedia information is a kind of information with a specific format, it needs to be parsed using multimedia information parsing data to obtain the target warning multimedia information that can be output.

[0317] The subsequent user equipment outputs the target early warning multimedia information, when the target early warning multimedia information is a picture or text, the target early warning multimedia information can be displayed, when the target early warning multimedia information is audio, the target early warning multimedia information can be played, and when the target early warning multimedia information is a video, the target early warning multimedia information can be displayed and played, so that the rescue personnel can know the target early warning multimedia information and take corresponding rescue actions, and the life and property safety of the user is improved.

[0318] It should be noted that steps S301-S305 are implemented through a network layer, and steps S306-S309 and steps S310-S313 are implemented through an application layer. The network layer and the application layer correspond to different transmission interfaces and transmission modules, and therefore, the early warning server sends the second early warning message and the multimedia information analysis data separately.

[0319] The disaster early warning method provided in this embodiment sends a second early warning message to a core network device through an early warning server, and the core network device sends a multicast session establishment request to a base station according to a communication type indicated in the second early warning message. After the base station establishes a multicast session with the core network device, the base station sends multicast radio bearer configuration data to a user equipment. The user equipment establishes a multicast radio bearer with the base station according to the multicast radio bearer configuration data. Then, the early warning server, the core network device, and the base station send multimedia information analysis data and initial early warning multimedia information to the user equipment through the multicast session and the multicast radio bearer. The user equipment analyzes the initial early warning multimedia information according to the multimedia information analysis data to obtain target early warning multimedia information. This scheme establishes a multicast session through the core network device and the base station, and establishes a multicast radio bearer through the base station and the user equipment, thereby realizing multicast transmission of multimedia information.

[0320] Figure 4 The flowchart of the fourth embodiment of the disaster early warning method provided in this application is based on the third embodiment, and this embodiment of this application describes the case where the base station sends a second response message to the early warning server through the core network device, the user equipment sends a multicast response message to the base station, and the user equipment sends a multicast channel establishment success response message to the early warning server through the base station and the core network device. As shown in Figure 4 The disaster early warning method specifically includes the following steps:

[0321] S401: After receiving the multicast session establishment request sent by the core network device, the base station generates a multicast session establishment result according to whether the current service rate is less than a preset service rate threshold.

[0322] In this step, after the core network device sends the multicast session establishment request to the base station, the base station can receive the multicast session establishment request, and then determine whether the multicast session can be established with the core network device according to whether the current service rate is less than the preset service rate threshold, and generate a multicast session establishment result. The multicast session establishment result indicates that the multicast session establishment is successful or failed.

[0323] Specifically, if the current service rate is less than the preset service rate threshold, a multicast session establishment result indicating that the multicast session establishment is successful is generated; if the current service rate is greater than or equal to the preset service rate threshold, a multicast session establishment result indicating that the multicast session establishment is failed is generated.

[0324] S402: The base station sends a second response message to the core network device.

[0325] In this step, after the base station generates the multicast session establishment result, the base station sends a second response message to the core network device, so that the core network device knows which base stations establish the multicast session with the core network device and which base stations do not establish the multicast session with the core network device. The second response message includes the multicast session establishment result and the base station identifier of the base station.

[0326] It should be noted that the second response message also includes message name, session identifier, session description information, etc. The embodiments of the present application do not limit the content included in the second response message, which can be set according to actual conditions.

[0327] S403: After the core network device receives the second response message sent by the base station, the core network device sends the second response message to the early warning server.

[0328] In this step, after the base station sends the second response message to the core network device, the core network device can receive the second response message, and then in order for the early warning server to know which base stations establish the multicast session with the core network device and which base stations do not establish the multicast session with the core network device, the core network device needs to send the second response message to the early warning server.

[0329] It should be noted that if the multicast session establishment result in the received second response message indicates that the multicast session establishment is failed, the core network device can resend the multicast session establishment request to the base station.

[0330] S404: The early warning server receives the second response message sent by the core network device.

[0331] In this step, after the core network device sends the second response message to the early warning server, the early warning server can receive the second response message. Subsequently, the early warning server can output the second response message, so that the worker can check the base stations that do not establish the multicast session with the core network device for maintenance.

[0332] S405: After receiving the multicast radio bearer configuration data sent by the base station, the user equipment generates a multicast response message.

[0333] In this step, after receiving the multicast radio bearer configuration data sent by the base station, the user equipment may establish successfully or fail to establish when establishing the multicast radio bearer with the base station, and needs to generate a multicast response message. The multicast response message includes a multicast radio bearer establishment result, and the multicast radio bearer establishment result indicates that the multicast radio bearer is established successfully or fails.

[0334] S406: The user equipment sends the multicast response message to the base station.

[0335] In this step, in order to let the base station know which user equipment has not established the radio bearer, the user equipment needs to send the multicast response message to the base station.

[0336] S407: The base station receives the multicast response message sent by the user equipment.

[0337] In this step, after the user equipment sends the multicast response message to the base station, the base station can receive the multicast response message. In the case that the multicast radio bearer establishment result indicates that the multicast radio bearer fails to be established, the base station can send the multicast radio bearer configuration data to the user equipment again.

[0338] S408: After receiving the multimedia information analysis data sent by the base station, the user equipment sends a multicast channel establishment success response message to the base station.

[0339] In this step, after receiving the multimedia information analysis data sent by the base station, in order to let the early warning server know which user equipment has established the multicast radio bearer, the user equipment needs to send a multicast channel establishment success response message to the base station. The multicast channel establishment success response message includes the identifier of the user equipment.

[0340] It should be noted that the multicast channel establishment success response message can carry a message name, a session identifier, a service identifier, etc. The present embodiment does not limit the data carried by the multicast channel establishment success response message, which can be set according to actual conditions.

[0341] S409: After receiving the multicast channel establishment success response message sent by the user equipment, the base station sends the multicast channel establishment success response message to the core network device.

[0342] S410: After receiving the multicast channel establishment success response message sent by the base station, the core network device sends the multicast channel establishment success response message to the early warning server.

[0343] S411: The early warning server receives the multicast channel establishment success response message sent by the core network device.

[0344] In the above step, after the user equipment sends the multicast channel establishment success response message to the base station, the base station receives the multicast channel establishment success response message, and sends the multicast channel establishment success response message to the core network device. After the core network device receives the multicast channel establishment success response message, the core network device sends the multicast channel establishment success response message to the early warning server, and the early warning server can receive the multicast channel establishment success response message. Since the multicast channel establishment success response message includes the identifier of the user equipment, the early warning server can output the multicast channel establishment success response message, so that the staff can know which user equipment has established the multicast radio bearer, and the user equipment that has not established the multicast radio bearer can be repaired.

[0345] The disaster early warning method provided in the embodiment can improve the success rate of establishment of the multicast session by sending the second response message from the base station to the core network device, so that the core network device re-sends the multicast session establishment request to the base station that has not established the multicast session with the core network device. The second response message is sent from the core network device to the early warning server, so that the staff can repair the base station that has not established the multicast session with the core network device, ensuring normal operation of the base station. The multicast response message is sent from the user equipment to the base station, so that the base station re-sends the multicast radio bearer configuration data to the user equipment that has not established the multicast radio bearer with the base station device, improving the success rate of establishment of the multicast radio bearer. The multicast channel establishment success response message is sent from the user equipment to the early warning server through the base station and the core network device, so that the staff can repair the user equipment that has not established the multicast radio bearer with the base station device, ensuring normal operation of the user equipment.

[0346] Figure 5 The flowchart of the disaster early warning method provided in Embodiment Five of the present application is described in the present embodiment, in which the core network device and the base station establish a unicast session, the base station and the user equipment establish a unicast radio bearer, and the early warning server sends initial early warning multimedia information to the core network, and then sends the information to the user equipment through the unicast session and the unicast radio bearer, realizing unicast transmission of the multimedia information. As shown in Figure 5 The disaster early warning method specifically includes the following steps:

[0347] S501: The early warning server sends a third early warning message to the core network device.

[0348] After the disaster occurs, the demand for contacting a certain user in the disaster area alone can be met by using unicast transmission to send multimedia information to the user equipment of the user, so that the user can save himself.

[0349] In this step, the early warning server sends a third early warning message to the core network device, and the third early warning message includes a communication type indicating unicast communication, a base station identifier, and a user equipment identifier.

[0350] It should be noted that the third early warning message can also include a message name, an early warning type, and the like, and the embodiments of the present application do not limit the content included in the third early warning message, which can be set according to actual conditions.

[0351] It should be noted that the early warning information sending starting moment in this embodiment is a moment set by the staff according to the development of the disaster, which can be any moment of the day, and the embodiments of the present application do not limit the early warning information sending starting moment, which can be set according to actual conditions.

[0352] It should be noted that the way of triggering the early warning server to send the third early warning message to the core network device can be: receiving the third early warning message sent by the third party platform. It can also be: obtaining the third early warning message input by the user. It can also be: obtaining the third early warning message from the third party platform. The embodiments of the present application do not limit the way of triggering the early warning server to send the third early warning message to the core network device, which can be determined according to actual conditions.

[0353] S502: After the core network device receives the third early warning message sent by the early warning server, if the communication type indicates unicast communication, the core network device sends a unicast session establishment request to the base station corresponding to the base station identifier.

[0354] In this step, after the early warning server sends the third early warning message to the core network device, the core network device can receive the third early warning message, and then determine the communication mode according to the communication type therein. Since the communication type in the third early warning message indicates unicast communication, the communication mode is unicast communication.

[0355] Further, the base station corresponding to the base station identifier is sent a unicast session establishment request, and the unicast session establishment request includes a user equipment identifier.

[0356] S503: After the base station receives the unicast session establishment request sent by the core network device, if the current service rate is less than a preset service rate threshold, the base station establishes a unicast session with the core network device.

[0357] In this step, after the core network device sends the unicast session establishment request to the base station, the base station can receive the unicast session establishment request, and then determine whether the unicast session can be established according to the size of the current service rate of the base station.

[0358] If the base station determines that the current service rate is less than the preset service rate threshold, it means that the current network load of the base station is small, and then the base station establishes a unicast session with the core network device.

[0359] It should be noted that if the base station determines that the current service rate is greater than or equal to the preset service rate threshold, it means that the current network load of the base station is large, and the unicast session with the core network device is not established.

[0360] S504: The base station sends unicast radio bearer configuration data to the user equipment corresponding to the user equipment.

[0361] In this step, after the base station establishes a unicast session with the core network device, in order to transmit multimedia information subsequently, it needs to send unicast radio bearer configuration data to the user equipment corresponding to the user equipment. So that the user equipment establishes a unicast radio bearer with the base station to transmit multimedia information.

[0362] S505: After the user equipment receives the unicast radio bearer configuration data sent by the base station, the user equipment establishes a unicast radio bearer with the base station according to the unicast radio bearer configuration data.

[0363] In this step, after the base station sends unicast radio bearer configuration data to the user equipment, the user equipment establishes a unicast radio bearer with the base station according to the unicast radio bearer configuration data.

[0364] S506: The early warning server sends multimedia information analysis data to the core network device.

[0365] In this step, after the early warning server sends the third early warning message to the core network device, it will send multimedia information analysis data to the core network device at a third preset time interval. So that the core network device sends the multimedia information analysis data to the user equipment through the base station, and the user equipment uses the multimedia information analysis data to analyze the initial early warning multimedia information.

[0366] The reason why the early warning server interval the sending time of the third early warning message and the sending time of the multimedia information analysis data by a third preset time interval is to ensure that the unicast session between the core network device and the base station is established.

[0367] It should be noted that the third preset time interval can be 50 milliseconds, 100 milliseconds, 1 second, 3 seconds, etc. The third preset time interval is not limited by the present application and can be set according to actual conditions.

[0368] It should be noted that the multimedia information analysis data can carry message name, session type, priority, etc. The data carried by the multimedia information analysis data is not limited by the present application and can be set according to actual conditions.

[0369] S507: After the core network device receives the multimedia information analysis data sent by the early warning server, the core network device sends the multimedia information analysis data to the base station through the unicast session with the base station.

[0370] In this step, after the early warning server sends the multimedia information parsing data to the core network device, the core network device can receive the multimedia information parsing data. In order to enable the user equipment to receive the multimedia information parsing data, the core network device sends the multimedia information parsing data to the base station through a unicast session with the base station.

[0371] S508: After the base station receives the multimedia information parsing data sent by the core network device through a unicast session with the core network device, the base station sends the multimedia information parsing data to the user equipment through a unicast radio bearer with the user equipment.

[0372] In this step, after the core network device sends the multimedia information parsing data to the base station, the base station can receive the multimedia information parsing data through a unicast session with the core network device, and then send the multimedia information parsing data to the user equipment through a unicast radio bearer with the user equipment.

[0373] S509: The user equipment receives the multimedia information parsing data sent by the base station through a unicast radio bearer with the base station.

[0374] In this step, after the base station sends the multimedia information parsing data to the user equipment, the user equipment can receive the multimedia information parsing data through a unicast radio bearer with the base station.

[0375] S510: The early warning server sends initial early warning multimedia information to the core network device.

[0376] In this step, after the early warning server sends the multimedia information parsing data, the early warning server sends initial early warning multimedia information to the core network device.

[0377] It should be noted that the initial early warning multimedia information can include an early warning type, and the early warning type is an earthquake, a tsunami, a typhoon, a flood, etc.

[0378] S511: After the core network device receives the initial early warning multimedia information sent by the early warning server, the core network device sends the initial early warning multimedia information to the base station through a unicast session with the base station.

[0379] In this step, after the early warning server sends the initial early warning multimedia information to the core network device, the core network device can receive the initial early warning multimedia information, and then send the initial early warning multimedia information to the base station through a unicast session with the base station.

[0380] S512: After the base station receives the initial early warning multimedia information sent by the core network device through a unicast session with the core network device, the base station sends the initial early warning multimedia information to the user equipment through a unicast radio bearer with the user equipment.

[0381] In this step, after the core network device sends the initial warning multimedia information to the base station, the base station can receive the initial warning multimedia information through the unicast session with the core network device. Since the unicast radio bearer between the base station and the user equipment has been established, the initial warning multimedia information is further sent to the user equipment through the unicast radio bearer with the user equipment.

[0382] S513: After the user equipment receives the initial warning multimedia information sent by the base station through the unicast radio bearer with the base station, the initial warning multimedia information is parsed according to the multimedia information parsing data, and the target warning multimedia information is obtained.

[0383] In this step, after the base station sends the initial warning multimedia information to the user equipment, the user equipment can receive the initial warning multimedia information through the unicast radio bearer with the base station, and then parse the initial warning multimedia information according to the multimedia information parsing data to obtain the target warning multimedia information.

[0384] Since the initial warning multimedia information is a kind of information with a specific format, it needs to be parsed using multimedia information parsing data to obtain the target warning multimedia information that can be output.

[0385] The user equipment outputs the target warning multimedia information. When the target warning multimedia information is a picture or text, the target warning multimedia information can be displayed. When the target warning multimedia information is audio, the target warning multimedia information can be played. When the target warning multimedia information is video, the target warning multimedia information can be displayed and played. In this way, the user can learn the target warning multimedia information and improve the safety of life and property.

[0386] It should be noted that the user equipment can send an interactive message to the warning server, and the interactive message can include multimedia information. The user equipment sends the interactive message to the base station through the unicast radio bearer with the base station. The base station sends the interactive message to the core network device through the unicast session with the core network device. The core network device sends the interactive message to the warning server, and the warning server can output the interactive message so that the staff can know the content sent by the user.

[0387] It should be noted that steps S501-S505 are implemented through a network layer, and steps S506-S509 and steps S510-S513 are implemented through an application layer. The network layer and the application layer correspond to different transmission interfaces and transmission modules, so the warning server sends the third warning message and the multimedia information parsing data separately.

[0388] The disaster early warning method provided in the embodiment comprises the following steps:

[0389] Figure 6 The flowchart of the disaster early warning method provided in Embodiment Six of the present application is based on Embodiment Five, and the present embodiment explains the case that the base station sends the third response message to the early warning server through the core network device, the user equipment sends the unicast response message to the base station, and the user equipment sends the unicast channel establishment success response message to the early warning server through the base station and the core network device. As shown in Figure 6

[0390] S601: After the base station receives the unicast session establishment request sent by the core network device, the base station generates a unicast session establishment result according to whether the current service rate is less than a preset service rate threshold.

[0391] In this step, after the core network device sends the unicast session establishment request to the base station, the base station can receive the unicast session establishment request, and then determine whether the unicast session can be established with the core network device according to whether the current service rate is less than a preset service rate threshold, and generate a unicast session establishment result. The unicast session establishment result indicates the success or failure of the unicast session establishment.

[0392] Specifically, if the current service rate is less than the preset service rate threshold, a unicast session establishment result indicating the success of the unicast session establishment is generated; if the current service rate is greater than or equal to the preset service rate threshold, a unicast session establishment result indicating the failure of the unicast session establishment is generated.

[0393] S602: The base station sends a third response message to the core network device.

[0394] In this step, after the base station generates the unicast session establishment result, the base station sends a third response message to the core network device, so that the core network device knows whether the base station and the core network device establish the unicast session. The third response message comprises the unicast session establishment result and the base station identifier of the base station. ​

[0395] It should be noted that the third response message further includes a message name, a session identifier, session description information, etc. The embodiments of the present application do not limit the content included in the third response message, which can be set according to actual conditions.

[0396] S603: After receiving the third response message sent by the base station, the core network device sends the third response message to the early warning server.

[0397] In this step, after the base station sends the third response message to the core network device, the core network device can receive the third response message. In order for the early warning server to know whether the base station and the core network device establish a unicast session, the core network device needs to send the third response message to the early warning server.

[0398] It should be noted that if the unicast session establishment result in the received third response message indicates that the unicast session establishment fails, the core network device can re-send a unicast session establishment request to the base station.

[0399] S604: The early warning server receives the third response message sent by the core network device.

[0400] In this step, after the core network device sends the third response message to the early warning server, the early warning server can receive the third response message. Subsequently, the early warning server can output the third response message, so that the worker can check the base station that does not establish a unicast session with the core network device for maintenance.

[0401] S605: After receiving the unicast radio bearer configuration data sent by the base station, the user equipment generates a unicast response message.

[0402] In this step, when establishing a unicast radio bearer with the base station, the user equipment may establish successfully, or may establish successfully or unsuccessfully, and needs to generate a unicast response message. The unicast response message includes a unicast radio bearer establishment result, which indicates that the unicast radio bearer establishment is successful or unsuccessful.

[0404] In this step, in order for the base station to know whether the user equipment establishes a radio bearer, the user equipment needs to send the unicast response message to the base station.

[0405] S607: The base station receives the unicast response message sent by the user equipment.

[0406] In this step, after the user equipment sends the unicast response message to the base station, the base station can receive the unicast response message. In the case that the unicast radio bearer establishment result indicates that the unicast radio bearer establishment fails, the base station can send the unicast radio bearer configuration data to the user equipment again.

[0407] S608: After the user equipment receives the multimedia information parsing data sent by the base station, the user equipment sends a unicast channel establishment success response message to the base station.

[0408] In this step, after the user equipment receives the multimedia information parsing data sent by the base station, in order for the early warning server to know whether the user equipment establishes the unicast radio bearer, the user equipment needs to send a unicast channel establishment success response message to the base station, and the unicast channel establishment success response message includes the identifier of the user equipment.

[0409] It should be noted that the unicast channel establishment success response message can carry a message name, a session identifier, a service identifier, etc., and the present embodiment does not limit the data carried by the unicast channel establishment success response message, which can be set according to actual conditions.

[0410] S609: After the base station receives the unicast channel establishment success response message sent by the user equipment, the base station sends the unicast channel establishment success response message to the core network device.

[0411] S610: After the core network device receives the unicast channel establishment success response message sent by the base station, the core network device sends the unicast channel establishment success response message to the early warning server.

[0412] S611: The early warning server receives the unicast channel establishment success response message sent by the core network device.

[0413] In the above steps, after the user equipment sends the unicast channel establishment success response message to the base station, the base station receives the unicast channel establishment success response message and sends the unicast channel establishment success response message to the core network device. After the core network device receives the unicast channel establishment success response message, the core network device sends the unicast channel establishment success response message to the early warning server, and the early warning server can receive the unicast channel establishment success response message. Since the unicast channel establishment success response message includes the identifier of the user equipment, the early warning server can output the unicast channel establishment success response message, so that the staff can know which user equipment has established the unicast radio bearer, and the user equipment that has not established the unicast radio bearer can be repaired.
