Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a message sending method, apparatus, communication equipment and storage medium. Background Art

[0002] According to the standards of 3GPP (3rd Generation Partnership Project), existing mobile communication networks only support emergency calls (for example, one-click alarm) functions, and do not yet support emergency text message sending functions.

[0003] Based on the existing ordinary SMS sending method, it can be known that even if emergency messages are sent based on the existing ordinary SMS, the message sending address (i.e., the alarm phone number) and the corresponding emergency message content need to be filled in the ordinary SMS to achieve the purpose of sending the emergency message. This method has a low efficiency in message sending due to the complex operation, which seriously affects the timeliness of message sending.

[0070] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0071] The message sending method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown.

[0072] The AMF network element generates a second message based on the first emergency information in response to the first message sent by the user terminal and the first emergency information. The AMF network element sends a second non-access layer message to the short message service device; wherein the second message is used to instruct the short message service device to determine the message sending address and the emergency message content, and send the emergency message content to the emergency service device pointed to by the message sending address; the first message is a non-access layer message;.

[0073] Among them, the AMF (Access and Mobility Management Function) network element is mainly responsible for identity authentication, authorization, registration, mobility management and connection management functions for user terminals.

[0074] User terminal refers to the terminal device that needs to send emergency messages. It can be a smart terminal such as a mobile phone or computer, or a smart wearable device such as a smart watch or smart bracelet.

[0075] Short Message Service Equipment refers to equipment related to the Short Message Service Function (SMSF), and refers to functional equipment responsible for processing short message (eg, SMS) services in a mobile communication network.

[0076] In an alternative embodiment, if Figure 2 As shown, a message sending method is provided, which can be applied to Figure 1 In the AMF network element shown. In this embodiment, the method includes the following steps:

[0077] S201, in response to a first message carrying first emergency information sent by a user terminal, generate a second message based on the first emergency information.

[0078] Among them, the user terminal refers to the terminal device that needs to send an emergency message, which can be a smart terminal such as a mobile phone or a computer, or a smart wearable device such as a smart watch or a smart bracelet. The first emergency information refers to the associated information of the emergency message that needs to be sent. The first message is a non-access layer message, which refers to a NAS (Non-AccessStratum) protocol message sent by the user terminal to the AMF network element, for example, it can be a UL NAS TRANSPORT message (adding the first emergency information to the UL NAS TRANSPORT message). The second message refers to the message encapsulated and generated by the AMF network element based on the first emergency information.

[0079] Optionally, in this embodiment, the user terminal may send a first message carrying first emergency information to the AMF network element directly or indirectly through other network element devices.

[0080] As an optional implementation of the embodiment of the present application, in response to a first message carrying first emergency information sent by a user terminal, based on the first emergency information, the emergency message content is obtained (eg, parsed and extracted), and based on the emergency message content, a second message is generated.

[0081] As another optional implementation of the embodiment of the present application, in response to a first message carrying first emergency information sent by a user terminal, based on the first emergency information, the emergency message content and the emergency event type identifier are obtained (for example, parsed and extracted). Based on the emergency message content and the emergency event type identifier, a second message is generated. The emergency event type identifier indicates a unique identifier of an event type (for example, firefighting, public security, etc.) used to characterize an emergency event (for example, an alarm event). For example, it can be an English identifier of police, ambulance, fire, marine, or a digital identifier.

[0082] In order to make the emergency message more indicative and improve the efficiency of sending the emergency message, as well as to reduce the data volume of the emergency message, in some embodiments, the first emergency information includes but is not limited to the emergency event type identifier and the first terminal position of the user terminal. Optionally, in this implementation, the first message is sent by the user terminal after detecting that the user triggers the emergency message sending component. And the emergency event type identifier is determined by the user terminal according to the component type of the emergency message sending component. Exemplarily, if the emergency message sending control is a physical button on the user terminal, different physical buttons correspond to different emergency event types. When in use, after the user triggers the physical button, the user terminal determines the emergency event type according to the physical button triggered by the user, and determines the emergency event type identifier according to the emergency event type. Exemplarily, if the emergency message sending control is an application control on the application on the user terminal (for example, a control on the emergency message sending interface (for example, an alarm interface) on the APP), different application controls correspond to different emergency event types. When in use, after the user triggers the application control, the user terminal determines the emergency event type according to the application control triggered by the user, and determines the emergency event type identifier according to the emergency event type. Among them, the first terminal position refers to the location information of the user terminal obtained by the user terminal itself. Optionally, the user terminal may obtain the first terminal location based on GPS (Global Positioning System), Beidou, WiFi, Bluetooth, cellular network, etc.

[0083] Based on the above embodiments, if the first emergency information includes but is not limited to the emergency event type identifier and the first terminal location of the user terminal, an optional implementation of the embodiment of the present application is to generate a second message based on the first emergency information. An optional implementation is to generate a second message based on the emergency event type identifier and the first terminal location of the user terminal.

[0084] S202: Send a second message to a short message service device.

[0085] The second message is used to instruct the short message service device to determine the message sending address and the emergency message content, and send the emergency message content to the emergency service device pointed to by the message sending address. The short message service device refers to the short message service function (Short Message Service Function, SMSF) related equipment, which refers to the functional equipment responsible for processing short message (for example, SMS message) services in the mobile communication network.

[0086] As an optional implementation of the embodiment of the present application, the AMF network element sends a second message to the short message service device through other devices (for example, other network element devices).

[0087] As another optional implementation of the embodiment of the present application, the AMF network element sends a second message to the short message service device by calling a network element interface (for example, Nsmsf_SMService_UplinkSMS interface).

[0088] Optionally, an optional implementation method for the short message service device in this embodiment to determine the message sending address and the emergency message content is that the short message service device sends the first emergency information to an intelligent analysis device (such as an NWDAF (Network Data Analytics Function) network element), and the intelligent analysis device determines the message sending address and the emergency message content based on the first emergency information.

[0089] The above-mentioned message sending method, in response to the first message carrying the first emergency information sent by the user terminal, generates a second message based on the first emergency information; sends a second non-access layer message to the short message service device; wherein the second message is used to instruct the short message service device to determine the message sending address and the emergency message content, and send the emergency message content to the emergency service device pointed to by the message sending address. This application can not only achieve the purpose of sending the emergency message content based on the non-access layer, but also the AMF network element can generate a second message based on the first emergency information after receiving the first message sent by the user terminal, and send the second message to the short message service device, so that the short message service device determines the message sending address and the emergency message content based on the second message, and sends the emergency message content to the emergency service device pointed to by the message sending address. Not only does it achieve the purpose of sending the emergency message content through the non-access layer, but the short message service device can automatically determine the message sending address and the emergency message content based on the second message, and can send the emergency message content without the user manually entering the message sending address and the emergency message content, which effectively improves the efficiency of sending the emergency message content. Furthermore, the present application does not need to consider whether the user terminal supports the short message protocol stack or the IMS protocol stack, and can achieve the purpose of sending emergency message content based on non-access layer messages, thereby increasing the functions of the user terminal and expanding the application scope of the terminal.

[0090] In one of the embodiments, the content of the emergency message finally sent is made more accurate, such as Figure 3 As shown, an optional implementation of generating a second message based on the first emergency information in S201 includes:

[0091] S301: Acquire terminal location information of a user terminal.

[0092] Among them, the terminal location information includes the second terminal location of the user terminal and / or the terminal movement trend information of the user terminal. The second terminal location refers to the location information of the user terminal obtained by the AMF network element. Since the AMF network element has a mobile management function for the user terminal, the second terminal location of the user terminal can be obtained. The terminal movement trend information refers to the movement trend information of the user terminal obtained by obtaining the terminal location of the user terminal in real time and performing intelligent analysis. The intelligent analysis device can be but is not limited to an NWDAF network element.

[0093] Optionally, in this embodiment, if the terminal location information includes terminal movement trend information of the user terminal, an optional implementation method for the AMF network element to obtain the terminal movement trend information of the user terminal is to send a movement trend acquisition request to the NWDAF network element, so that the NWDAF network element can feedback the terminal movement trend information of the user terminal based on the movement trend acquisition request.

[0094] S302: Generate a second message according to the terminal location information and the first emergency information.

[0095] As an optional implementation of the embodiment of the present application, the terminal location information and the first emergency information are packaged to generate a second message.

[0096] As another optional implementation of the embodiment of the present application, a message template of a non-access layer message is obtained, and the terminal location information and the first emergency information are added to the message template to obtain a second message.

[0097] In this embodiment, the terminal location information of the user terminal is obtained; wherein the terminal location information includes the second terminal location of the user terminal and / or the terminal movement trend information of the user terminal. A second message is generated according to the terminal location information and the first emergency information, so that the message content of the generated second message is richer, and the terminal location contained in the final generated emergency message content is more accurate.

[0098] On the basis of the above embodiment, in order to make the content of the emergency message sent more accurate and to determine the message sending address more accurately, the second message is also used to instruct the short message service device to determine the message sending address based on the emergency event type identifier in the first emergency information, and to determine the emergency message content based on the first terminal location and terminal location information.

[0099] Optionally, in this embodiment, the short message service device determines the message sending address based on the emergency event type identifier in the first emergency information. An optional implementation method is to determine the message sending address according to the emergency event type identifier and the address list. The address list records multiple message sending addresses, each message sending address corresponds to an emergency event identifier. Exemplarily, the address list is as follows: Figure 4 As shown, if the emergency event type is identified as "sos.police", the message sending address is "12110020". It should be noted that the message sending address can be a device IP address or a communication number (for example, an international mobile subscriber identity number).

[0100] Optionally, in this embodiment, another optional implementation method for the short message service device to determine the message sending address based on the emergency event type identifier in the first emergency information is to determine the third terminal location of the user terminal based on the first terminal location and terminal location information in the first emergency message. For example, the first terminal location and terminal location information are sent to an intelligent analysis device (for example, an NWDAF network element) or other location prediction tools (for example, a location prediction model) to determine the third terminal location of the user terminal. Based on the third terminal location, the current area to which the user terminal belongs is determined, and the message sending address is determined based on the current area and the address list. The address list includes the emergency event type identifier and the message sending address corresponding to each emergency event type identifier, as well as the area to which each message sending address corresponds.

[0101] Optionally, in this embodiment, the short message service device determines the emergency message content based on the first terminal location and the terminal location information. An optional implementation method is to determine the third terminal location of the user terminal based on the first terminal location and the terminal location information in the first emergency message. For example, the first terminal location and the terminal location information are sent to an intelligent analysis device (for example, an NWDAF network element) or other location prediction tools (for example, a location prediction model) to determine the third terminal location of the user terminal. Based on the third terminal location, the emergency message content is determined. For example, the third terminal location is used as the emergency message content.

[0102] Based on this embodiment, not only the accuracy of the emergency message content and the message sending address is effectively improved, but the emergency message content and the message sending address can also be automatically determined without manual input by the user, thereby effectively improving the efficiency of emergency message sending.

[0103] On the basis of the above embodiment, in order to send the emergency message content more efficiently, the second message is also used to instruct the short message service device to send the emergency short message to the emergency service device pointed to by the message sending address through the short message center device; wherein, the emergency short message carries the emergency message content, and the short message center device refers to the SMSC (Short Message Service Center, Short Message Service Center) device. Optionally, the emergency short message is an SMS message, that is, a short message message. An optional implementation of this embodiment is that the short message service device generates an emergency short message based on the message sending address and the emergency message content, and sends the emergency short message to the short message center device. The short message center device sends the emergency short message to the emergency service device pointed to by the message sending address. Another optional implementation of this embodiment is that the first message also carries a preset message template (for example, SMS payload, that is, a short message template), and the second message sent by the AMF network element to the short message service device also carries the preset message template. After determining the content of the emergency message and the message sending address, the AMF network element adds the message sending address to the address field in the preset message template, and adds the emergency message content to the content field in the preset message template to obtain an emergency short message. The emergency short message is sent to the short message center device, and the short message center device sends the emergency short message to the emergency service device pointed to by the message sending address. For example, if the emergency short message is an alarm short message, the alarm short message is sent to the alarm service center device pointed to by the message sending address.

[0104] In an alternative embodiment, if Figure 5 As shown, a message sending method is provided, which can be applied to Figure 1 In the short message service device shown. In this embodiment, the method includes the following steps:

[0106] Among them, the second message is generated by the AMF network element based on the first emergency information when it receives the first message carrying the first emergency information sent by the user terminal.

[0107] Among them, the user terminal refers to the terminal device that needs to send an emergency message, which can be a smart terminal such as a mobile phone, a computer, or a smart wearable device such as a smart watch or a smart bracelet. The first emergency information refers to the associated information of the emergency message that needs to be sent. The first message refers to the NAS (Non-Access Stratum) protocol message sent by the user terminal to the AMF network element, for example, it can be a UL NAS TRANSPORT message (the first emergency information is added to the UL NAS TRANSPORT message). The second message refers to the NAS protocol message encapsulated and generated by the AMF network element based on the first emergency information.

[0108] It should be noted that the implementation method of the AMF network element generating the second message based on the first emergency information has been detailed in the above embodiment and will not be repeated here.

[0109] Optionally, in this embodiment, the second message may also be generated by the AMF network element based on the terminal location information of the user terminal and the first emergency information; wherein the terminal location information is obtained by the AMF network element after receiving the first message; the terminal location information includes the second terminal location of the user terminal and / or the terminal movement trend information of the user terminal. It should be noted that the specific implementation method is described in detail in the above embodiment and will not be repeated here.

[0110] Optionally, the first emergency information includes but is not limited to a first terminal location of the user terminal and an emergency event type identifier.

[0111] Optionally, the first message is sent to the AMF network element by the user terminal after detecting that the user triggers the emergency message sending component. The emergency event type identifier is determined by the user terminal according to the component type of the emergency message sending component. Exemplarily, if the emergency message sending control is a physical button on the user terminal, different physical buttons correspond to different emergency event types. When in use, after the user triggers the physical button, the user terminal determines the emergency event type according to the physical button triggered by the user, and determines the emergency event type identifier according to the emergency event type. Exemplarily, if the emergency message sending control is an application control on an application on the user terminal (for example, a control on the emergency message sending interface (for example, an alarm interface) on an APP), different application controls correspond to different emergency event types. When in use, after the user triggers the application control, the user terminal determines the emergency event type according to the application control triggered by the user, and determines the emergency event type identifier according to the emergency event type. Among them, the first terminal location refers to the location information of the user terminal obtained by the user terminal itself. Optionally, the user terminal can obtain the first terminal location based on GPS, Beidou, WiFi, Bluetooth, cellular network, etc.

[0112] S502: Determine a message sending address and emergency message content based on the second message.

[0114] S503: Send the emergency message content to the emergency service device pointed to by the message sending address.

[0115] As an optional implementation of the embodiment of the present application, the emergency message content is sent directly to the emergency service device pointed to by the message sending address.

[0116] As another optional implementation of the embodiment of the present application, an emergency short message is sent to the emergency service device pointed to by the message sending address through a short message center device; wherein the emergency short message carries the emergency message content, and the short message center device refers to an SMSC (Short Message Service Center, Short Message Service Center) device. Optionally, the emergency short message is an SMS message, that is, a short message message. An optional implementation of this embodiment is that the short message service device generates an emergency short message based on the message sending address and the emergency message content, and sends the emergency short message to the short message center device. The short message center device sends the emergency short message to the emergency service device pointed to by the message sending address. Another optional implementation of this embodiment is that the first message also carries a preset message template (for example, SMS payload, that is, a short message template), and the second message sent by the AMF network element to the short message service device also carries the preset message template. After determining the emergency message content and the message sending address, the AMF network element adds the message sending address to the address field in the preset message template, and adds the emergency message content to the content field in the preset message template to obtain an emergency short message. The emergency short message is sent to the short message center device, and the short message center device sends the emergency short message to the emergency service device pointed to by the message sending address. For example, if the emergency short message is an alarm short message, the alarm short message is sent to the alarm service center device pointed to by the message sending address.

[0117] In this embodiment, a second message sent by an AMF network element is received; wherein the second message is generated by the AMF network element based on the first emergency information when the AMF network element receives a first message carrying the first emergency information sent by a user terminal; based on the second message, the message sending address and the emergency message content are determined; and the emergency message content is sent to the emergency service device pointed to by the message sending address. Not only can the purpose of sending the emergency message content be achieved based on the non-access layer, but also after receiving the first message sent by the user terminal, the AMF network element can generate a second message based on the first emergency information and send the second message to the short message service device, so that the short message service device determines the message sending address and the emergency message content based on the second message, and sends the emergency message content to the emergency service device pointed to by the message sending address. Not only can the purpose of sending the emergency message content through the non-access layer be achieved, but also the short message service device can automatically determine the message sending address and the emergency message content based on the second message, and the emergency message content can be sent without the user manually entering the message sending address and the emergency message content, which effectively improves the efficiency of sending the emergency message content.

[0118] In one embodiment, in order to more accurately determine the message sending address and the content of the emergency message, such as Figure 6 As shown, another optional implementation of S502 includes:

[0119] S601: Determine a message sending address based on an emergency event type identifier in first emergency information.

[0120] As an optional implementation of the embodiment of the present application, the message sending address is determined according to the emergency event type identifier and the address list. The address list records multiple message sending addresses, each message sending address corresponds to an emergency event identifier. For example, the address list is as follows: Figure 4 As shown, if the emergency event type is identified as "sos.police", the message sending address is "12110020". It should be noted that the message sending address can be a device IP address or a communication number (for example, an international mobile subscriber identity number).

[0121] As another optional implementation of the embodiment of the present application, the third terminal location of the user terminal is determined based on the first terminal location and terminal location information in the first emergency message. For example, the first terminal location and terminal location information are sent to an intelligent analysis device (e.g., NWDAF network element) or other location prediction tools (e.g., location prediction model) to determine the third terminal location of the user terminal. According to the third terminal location, the current area to which the user terminal belongs is determined, and the message sending address is determined based on the current area and the address list. The address list includes an emergency event type identifier and a message sending address corresponding to each emergency event type identifier, as well as the area to which each message sending address corresponds.

[0122] S602: Determine the content of the emergency message based on the first terminal location and terminal location information.

[0123] Optionally, in this embodiment, the third terminal location of the user terminal is determined based on the first terminal location and terminal location information in the first emergency message. For example, the first terminal location and terminal location information are sent to an intelligent analysis device (e.g., NWDAF network element) or other location prediction tools (e.g., location prediction model) to determine the third terminal location of the user terminal. Based on the third terminal location, the emergency message content is determined. For example, the third terminal location is used as the emergency message content.

[0124] In this embodiment, the message sending address is determined based on the emergency event type identifier in the first emergency information. The emergency message content is determined based on the first terminal location and the terminal location information, so that the message sending address and emergency message content obtained in the end are more accurate. In addition, this application does not require the user to manually enter the message sending address and emergency message content, which greatly improves the efficiency of emergency message sending.

[0125] In one embodiment, if Figure 7 As shown, another optional implementation of a message sending method includes:

[0126] S701, the AMF network element receives a first message carrying first emergency information sent by a user terminal.
