[0002] Traditional broadcasting, interactive personality TV (IPTV), and over the top (OTT) video services from Internet companies are increasingly unable to meet the viewing needs of viewers. The integration of social attributes is the future development direction of media services. Real-time content sharing through integration with the 3GPP RCS system is an important technical direction. Digital video broadcasting-internet (DVB-I) defines a set of integrated discovery mechanisms for traditional broadcasting, IPTV, and OTT. In order to support the integration of DVB and 3GPP RCS systems, the discovery capability of RCS services based on DVB-I is also an important research topic.

[0102] In order to facilitate understanding of the technical solutions provided by the embodiments of the present application, the technical terms involved in the embodiments of the present application are introduced below.

[0103] 1) Rich communication service (RCS) system or RCS system (also known as the fifth generation mobile communication system (5 thGeneration, 5G) message system), refers to a collection of services, including: voice calls, video calls, sharing services such as picture sharing and video sharing, IM services such as notification messages, status presentation, address book synchronization file sharing and instant messaging.

[0104] The following is an introduction to the technical solutions provided by the embodiments of the present application.

[0105] See also Figure 1 , introduces a 5G message (also known as RCS, the same below) architecture diagram. Figure 1 As shown, the 5G message architecture can include a 5G message center and a Maap system. Among them, the 5G message center (5G Message Center, 5GMC) device can also be called an RCS application server (application server, AS) with the ability to process text messages and basic multimedia messages, add a new network interface between the MaaP platform, access new MaaP industry users, and retain the same network interface as the SMS center in the network interface, support mobile Internet service content application service providers (service provider, SP) and SMS applications, and provide 5G message sending and receiving functions for terminal devices that support 5G messages. 5GMC devices support terminal devices to access directly through the Internet, such as China Mobile Internet (China Mobile Network, CMNET), including terminal devices accessing through 2G, 4G, 5G packet switching (packet switch, PS) domains and through wireless local area networks (wireless local area networks, WLAN) and other methods.

[0106] The MaaP system consists of a MaaP platform management module and a MaaP platform, which can also be called a MaaP device. The MaaP system and 5GMC are deployed separately. Among them, the MaaP platform management module is centrally deployed throughout the network, with two major areas for mutual backup, each set up in a data center in one area, responsible for the access management, authentication, merchant multimedia content upload and storage (such as avatars) and other functions of the MaaP service. The MaaP platform is deployed in the corresponding provinces in the areas corresponding to the 5GMCs of the same corresponding provinces and in the specific data centers (DC) in the corresponding areas, carrying interactive 5G message services, responsible for the access of MaaP services for government and enterprise users, multimedia message content upload, message review docking, message content storage and other functions.

[0107] Traditional broadcasting, interactive personality TV (IPTV), and over the top (OTT) video services from Internet companies are increasingly unable to meet the viewing needs of viewers. The integration of social attributes is the future development direction of media services. Real-time content sharing through integration with the 3GPP RCS system is an important technical direction. Digital video broadcasting-internet (DVB-I) defines a set of integrated discovery mechanisms for traditional broadcasting, IPTV, and OTT. In order to support the integration of DVB and 3GPP RCS systems, the discovery capability of RCS services based on DVB-I is also an important research topic.

[0108] See also Figure 2 , shows a service discovery process. Among them, the content / service provider (content / serviceprovider) sends the service list (service list) that can be provided to the service list server (service listserver). The service list server registers the access entry address (uniform resource locator, URL) of the service list to the service list registration device (service list registry). When a DVB-I client (client), such as a set-top box, wants to discover a service (service), the DVB-I client obtains the access entry address of the service list from the service list registration device through the address of the service list registration device. DVB-I then queries the service list through the access entry address. A service list may include service information, as shown in Table 1.

[0109]

[0110]

[0111] As shown in Table 1, service information mainly includes unique service ID, service name, provider name, service type, genre and service instance. Among them, the service types currently supported by DVB-I include linear-radio, on demand, on demand-radio, data, mosaic, etc.

[0112] If the service also has additional service capabilities through the associated application, the service information also includes the associated application information (linked application).

[0113] The example description of the provided services is shown in Table 2.

[0114] DVB-I provides service instances Priority Source type Delivery parameters Content attributes Related material

[0115] As shown in Table 2, it can be described by priority, source type, delivery parameters, content attributes, and related materials. Among them, source type describes the type of service source. Content attributes are used to identify the instance of the service, such as audio, video, captioning, and signing.

[0116] Currently, the DVB system does not support intercommunication with the 3GPP RCS system. Therefore, the client of the DVB system does not support the RCS service, that is, the client of the DVB system cannot intercommunication of RCS messages with the 3GPP terminal device.

[0117] In view of this, the embodiment of the present application provides a message transmission method. In this method, a message subsystem can be deployed on the video platform, such as Figure 3 As shown. The message subsystem is connected to the MaaP system in the form of a robot (Chatbot), which is responsible for forwarding RCS messages between devices that do not support RCS services, such as devices in the DVB system and 3GPP terminal devices. Based on the above scheme, by connecting the deployed message subsystem to the MaaP system, it is possible to implement message interaction between devices that do not support RCS services in the related technology and terminals that support RCS services (such as 3GPP terminal devices). The devices that do not support RCS services in the present invention may be set-top boxes, smart TVs, PADs, etc.

[0118] For the convenience of description, the set-top box is taken as an example as a device that does not support RCS services, and the terminal device is taken as an example as a 3GPP terminal device.

[0119] Usually, the robot (Chatbot) service provider, such as the operator of the message subsystem in this application, submits customer information, selects tariffs, applies for and activates an account, and obtains the robot ID (Chatbot_id). Therefore, the session initialization protocol (SIP) uniform resource identifier (URI) of the message subsystem is<Chatbot_id> @botplatform.rcs.chinamobile.com. When the terminal device needs to send an RCS message to the set-top box, since the destination address of the RCS message is the SIP URI of the message subsystem, the embodiment of the present application also needs to solve how the message subsystem sends the RCS message to the correct set-top box.

[0120] The following introduces the service discovery process of the DVB system.

[0121] See also Figure 4 , showing an exemplary flowchart of a message transmission method, which may include the following operations.

[0122] S401: The set-top box requests a service list from a service device.

[0123] For example, the set-top box can send a message to a service device such as Figure 2 The service list server (service listserver) shown sends a request message to request to obtain a service list.

[0124] S402: The service device sends a service list to the set-top box.

[0125] Correspondingly, the set-top box receives the service list from the service device.

[0126] The service list may include service information, such as service information supported by a set-top box.

[0127] In a possible implementation, the service information may include service information of the RCS service. That is, in the embodiment of the present application, the type of RCS service may be added to the service information of the DVB system. The content / service provider may configure the service manually offline or by the content / service provider interacting with the service device. The service information may include one or more of service type indication information, service instance information, and associated application information.

[0128] For example, the service type indication information (service type) indicates that the service is an RCS service. If the RCS service is natively supported by the DVB-I client, the service information includes service instance information (service instance). If the RCS service is supported by an application, the service information may also include linked application information (linked application), which may indicate the application supported by the RCS service.

[0129] In one possible case, the service instance information may also include a URI, such as a URI may be included in a transmission parameter. Optionally, the service instance information may also include a service access protocol and a service startup type. Among them, the service startup type is a user of an RCS service, such as after a set-top box is started, the service will automatically start.

[0130] The following table 3 introduces the service information of the RCS service provided by the embodiment of the present application.

[0131] Table 3: Example of service information for an RCS service

[0132]

[0133] As shown in Table 3, the service information of the RCS service can indicate that the service is an RCS service through the type (type). The service information can also include the genre (genre). If the RCS service is natively supported by the DVB-I client, the service information can include service instances (service instances). In the service instance, the transmission parameters (bidirectional delivery parameters) can include the service access address, and the service access protocol, such as hypertext transfer protocol (HTTP), SIP, etc. The launch type (launch type) indicates the user of the RCS service, and the service will start automatically. If the RCS service is supported by an application, the service information can also include a linked application (linked application), which can indicate the application supported by the RCS service.

[0134] based on Figure 4 With the solution shown, the DVB system can support the RCS service.

[0135] The following is a technical solution for the intercommunication of RCS messages between a set-top box and a terminal device. In order to send the RCS message to the correct set-top box, the message subsystem in the embodiment of the present application can obtain the corresponding relationship between the set-top box and the terminal device.

[0136] See also Figure 5, shows an exemplary flowchart of a message transmission method, which may include the following operations.

[0137] S501: The set-top box sends a first request message to the message subsystem.

[0138] Correspondingly, the message subsystem receives the first request message from the set-top box.

[0139] Wherein, the first request message may include a corresponding relationship between the second identifier of the set-top box and the third identifier of the first terminal device. Wherein, the second identifier can be used to identify the set-top box, such as a set-top box fixed code number, a public switched telephone network number (PSTN), a SIP URI constructed based on PSTN of the set-top box, or a set-top box factory number, etc. Similarly, the third identifier can be used to identify the first terminal device, such as a mobile subscriber number (mobile subscriber international integrated service digital network, MSISDN), or a SIP URI constructed based on MSISDN, or a public land mobile phone network number (International MobileSubscriber Identity, IMSI), or a domain name constructed based on IMSI, etc. Exemplarily, the first request message can be a registration request message, used to request to register the set-top box or to request to bind the set-top box and the first terminal device.

[0140] In one possible scenario, the set-top box can Figure 4 The service list obtained in the illustrated embodiment presents service information to the user, such as presenting service information to the user on a display device with a wired connection or a wireless connection. The user can select the RCS service on the display device, such as selecting the RCS service through a remote control or touch control, and input the third identifier of the first terminal device to be bound according to the prompt. The display device can send the third identifier of the first terminal device to the set-top box according to the content input by the user.

[0141] Optionally, if the RCS service needs to rely on an application, the set-top box can activate the application after the user selects the RCS service. The user can enter the third identifier of the first terminal device to be bound according to the prompt of the application. The display device can send the third identifier of the first terminal device to the management platform of the application according to the content input by the user. Since the application is activated by the set-top box, the management platform of the application can also obtain the second identifier of the set-top box.

[0142] After acquiring the third identifier, the set-top box or the application management platform may send a first request message to the message subsystem. The set-top box or the application management platform may send the first request message to the message subsystem according to the service access address of the RCS.

[0143] In a possible implementation, the first request message may be sent by the second terminal device through the video management platform to a message subsystem, and the second terminal device may be a terminal device bound when signing up for the RCS service. For example, the second terminal device may access the video management platform and send a first request message to the video management platform, and the first request message may include the second identifier of the set-top box and the third identifier of the first terminal device. It is understandable that the second identifier of the set-top box and the third identifier of the first terminal device may be input by the user, and the video management platform may obtain the input second identifier and third identifier. The video management platform may send a first request message to the message subsystem. Optionally, the video management platform may send a response message of the first request message to the second terminal device after authorization based on the contract information of the second terminal device.

[0144] In a possible implementation, when a user signs a contract to open an account, the video management platform sends a first request message to the message subsystem, and the first request message may include the second identifier of the set-top box and the third identifier of the first terminal device. It is understandable that when signing the contract, the video management platform obtains the second identifier and the third identifier.

[0145] Optional, Figure 5 The illustrated embodiment may further include the following operations S502 to S508 .

[0146] S502: The message subsystem sends a response message to the first request message.

[0147] Correspondingly, the set-top box or the application management platform receives a response message to the first request message from the message subsystem. Optionally, the response message to the first request message can be used to indicate that the set-top box has received the first request message or has obtained the corresponding relationship between the second identifier and the third identifier.

[0148] S503: The message subsystem sends a second message to the MaaP device.

[0149] Correspondingly, the MaaP device receives the second message from the message subsystem.

[0150] In an embodiment of the present application, the message subsystem can access the MaaP device in the form of a robot, and the message subsystem can call an application programming interface (API) to send a second message to the MaaP device. Among them, the second message is used to request the first terminal device to confirm the correspondence between the second identifier and the third identifier. The second message may include a first identifier of the first terminal device, and the first identifier may correspond to the third identifier. That is, the first identifier and the third identifier are the same, for example, the first identifier and the third identifier are both the SIP URI of the first terminal device; or the first identifier is constructed according to the third identifier, for example, the third identifier is an MSISDN, and the first identifier is a SIP URI determined based on the third identifier. The message subsystem can deduce each other based on the first identifier and the third identifier, such as the message subsystem can determine the third identifier based on the first identifier, or it can determine the first identifier based on the third identifier. Exemplarily, in the second message, the first identifier is the destination address field of the second message. The MaaP device can determine the first terminal device based on the first identifier.

[0151] In a possible implementation, the second message may include a first card message. The message subsystem may construct the first card message based on the second identifier of the set-top box (i.e., the first card message includes the second identifier). The first card message may include one or more of the suggested operations such as confirming binding, managing binding, sharing a card, and sending a message. The first card message including the suggested operation of confirming binding is used as an example for explanation.

[0152] S504: The MaaP device sends a response message of the second message to the message subsystem.

[0153] Correspondingly, the message subsystem receives a response message of the second message from the MaaP device. Optionally, the response message of the second message may indicate that the MaaP device has processed the second message or has received the second message. Exemplarily, the response message of the second message may be an HTTP status code 200 OK, indicating that the request has been successfully processed on the server.

[0154] S505: The MaaP device sends a second message to the first terminal device.

[0155] Correspondingly, the first terminal device receives the second message from the MaaP device.

[0156] In one possible scenario, the MaaP device may send the second message to the first terminal device through the 5GMC. For example, the MaaP device may call an API to send the second message to the 5GMC, and the 5GMC sends the second message to the first terminal device. Optionally, the 5GMC may send a response message of the second message to the MaaP device, such as an HTTP status code 200OK. The 5GMC may send the second message to the first terminal device through a SIP message. Optionally, the first terminal device may send a response message of the second message to the 5GMC, such as a SIP status code 200OK, to indicate that the request has been successfully processed or accepted.

[0157] S506: The first terminal device sends a third message to the MaaP device.

[0158] Correspondingly, the MaaP device receives a third message from the first terminal device, wherein the third message is used to instruct the first terminal device to confirm the correspondence between the second identifier and the third identifier.

[0159] For example, the first terminal device can display the content of the second message on the display interface, and the user can operate based on the display interface to confirm the corresponding relationship. For example, the screen displays: "Set-top box **** (**** represents the second identifier) ​​binding is confirmed. Please enter 1 to confirm." The first terminal device can send a third message to the 5GMC in response to the user's operation. For example, the user replies to the message, enters the message content "1", and sends it.

[0160] In one possible scenario, the first terminal device may send a third message to the MaaP device through the 5GMC. For example, the first terminal device may send a third message to the 5GMC, such as sending a SIP message to the 5GMC. The 5GMC may call an API to send the third message to the MaaP device. The third message may include a first identifier and a SIP URI of a message subsystem. Exemplarily, the first identifier may be a source address field of the third message, the source address field may be a SIP URI determined based on the third identifier of the first terminal device, and the destination address field is a SIP URI of the message subsystem.

[0161] In one possible implementation, the third message may be sent by the first terminal device based on the first card message. For example, the first terminal device may display the content of the first card message on the display interface, and the displayed card content includes the identification information of the set-top box, such as "the operation card of the set-top box **** (**** represents the second identification)", and multiple suggested operation options, such as binding confirmation, message sharing, message sending, etc. After the user selects the binding confirmation option, the first terminal device may send a third message to the MaaP device in response to the user's operation. Among them, the message content of the third message includes the second identification of the set-top box, and the second identification may be added to the message content of the third message according to the confirmation binding suggestion operation, for example, the second identification may be automatically added to the third message. The third message may also include the first identification, such as the first identification may be the source address field of the third message, the source address field may be a SIP URI determined based on the third identification of the first terminal device, and the destination address field is the SIP URI of the message subsystem.

[0162] S507: The MaaP device sends a third message to the message subsystem.

[0163] Correspondingly, the message subsystem receives a third message from the MaaP device.

[0164] Exemplarily, the MaaP device calls the API interface to send the third message to the message subsystem.

[0165] S508: The message subsystem saves the corresponding relationship between the second identifier and the third identifier.

[0166] The message subsystem can determine the corresponding third identifier according to the first identifier in the third message, thereby saving the second identifier and the third identifier. It can be understood that the correspondence between the second identifier and the third identifier can be a correspondence table or other forms, which is not specifically limited in this application.

[0167] Optionally, the message subsystem may also send a registration request confirmation message to the set-top box to indicate that the set-top box has been successfully registered or to indicate that the set-top box and the first terminal device have been bound.

[0168] based on Figure 5 In the illustrated embodiment, the message subsystem can obtain the correspondence between the second identifier of the set-top box and the third identifier of the first terminal device. Figure 5 In the embodiment shown, a technical solution is shown in which a set-top box requests to bind a set-top box to a first terminal device. Figure 6 A technical solution is shown in which a first terminal device requests binding of a set-top box with the first terminal device.

[0169] See also Figure 6, which is an exemplary flowchart of a message transmission method provided in an embodiment of the present application, may include the following operations.

[0170] S601: The set-top box sends a second request message to the message subsystem.

[0171] Correspondingly, the message subsystem receives a second request message from the set-top box.

[0172] The second request message may include the second identifier of the set-top box, and the second request message may request to register with the message subsystem. Exemplarily, the second request message may be a registration request message.

[0173] Optional, Figure 6 The illustrated embodiment may further include the following operation S602 .

[0174] S602: The message subsystem sends a response message to the second request message to the set-top box.

[0175] Correspondingly, the set-top box receives a response message to the second request message from the message subsystem.

[0176] The response message of the second request message may indicate that the registration is successful. Exemplarily, the response message of the second request message may be a registration request response message.

[0177] S603: The first terminal device sends a fourth message to the MaaP device.

[0178] Correspondingly, the MaaP device receives the fourth message from the first terminal device.

[0179] The fourth message may include the first identifier and the third content from the first terminal device, and the third content may include the second identifier. The fourth message may be used to request binding of the first terminal device and the set-top box. The first identifier corresponds to the third identifier, such as the first identifier and the third identifier are the same, for example, the first identifier and the third identifier are both the SIP URI of the first terminal device; or the first identifier is constructed according to the third identifier, such as the third identifier is the MSISDN, and the first identifier is the SIP URI determined based on the third identifier. The message subsystem can derive from each other based on the first identifier and the third identifier. Exemplarily, the first identifier is the source address field of the fourth message. The destination address field of the fourth message may be the SIP URI of the message subsystem.

[0180] In one possible scenario, the first terminal device may send the fourth message to the MaaP device through the 5GMC. For example, the first terminal device may send a SIP message to the 5GMC, and the SIP message may carry the fourth message. The 5GMC may call an API to send the fourth message to the MaaP device.

[0181] S604: The MaaP device sends a fourth message to the message subsystem.

[0182] Correspondingly, the MaaP device receives a fourth message from the message subsystem.

[0187] Correspondingly, the MaaP device receives a first confirmation message from the message subsystem. The destination address field of the first confirmation message is the SIP URI of the second terminal device. The source address field of the first confirmation message is the SIP URI of the message subsystem. The content of the first confirmation message includes the correspondence between the second identifier and the third identifier, which is used to request the second terminal device to confirm the correspondence. Exemplarily, the message subsystem can call an API to send the first confirmation message to the MaaP device.

[0188] S606: The MaaP device sends a first confirmation message to the second terminal device.

[0189] Correspondingly, the second terminal device receives the first confirmation message from the MaaP device.

[0190] In one possible scenario, the MaaP device may send a first confirmation message to the second terminal device through the 5GMC. For example, the MaaP device may call an API to send the first confirmation message to the 5GMC, and the 5GMC may call an API to send the first confirmation message to the second terminal device.

[0191] S607: The second terminal device sends a second confirmation message to the MaaP device.

[0192] Correspondingly, the MaaP device receives a second confirmation message from the second terminal device.

[0193] In one possible scenario, the second terminal device may send a second confirmation message to the MaaP device through the 5GMC. For example, the second terminal device may send a second confirmation message to the 5GMC, and the 5GMC may send a second confirmation message to the MaaP device. Exemplarily, the second confirmation message may include an HTTP status code of 200 OK.

[0194] S608: The MaaP device sends a second confirmation message to the message subsystem.

[0195] Correspondingly, the message subsystem receives a second confirmation message from the MaaP device.

[0196] S609: The message subsystem saves the corresponding relationship between the second identifier and the third identifier.

[0197] based on Figure 6 In the illustrated embodiment, based on the operation of the first terminal device, the message subsystem can also obtain the corresponding relationship between the second identifier and the third identifier.

[0198] The following introduces a technical solution for the first terminal device to send an RCS message to a set-top box.

[0199] See also Figure 7 , which is an exemplary flowchart of a message transmission method provided in an embodiment of the present application, may include the following operations.

[0200] S701: A first terminal device sends a first message to a MaaP device.

[0201] Correspondingly, the MaaP device receives the first message from the first terminal device.

[0202] The first message may include a first identifier and a first content, and the first content may be content sent by a user to a set-top box through a first terminal device. In S701, the first identifier may correspond to the third identifier (i.e., the first identifier and the third identifier are the same, or the first identifier is constructed according to the third identifier), such as the first identifier may be a source address field of the first message. Exemplarily, the first message is a text message or a file transfer message.

[0203] In one possible scenario, the first terminal device may send a first message to the MaaP device through the 5GMC. For example, the first terminal device may send a SIP message to the 5GMC, where the SIP message is the first message. Optionally, the 5GMC sends a SIP status code 200OK to the first terminal device. The 5GMC may send the first message to the MaaP device. Optionally, the MaaP device may send an HTTP status code 200OK to the 5GMC.

[0204] In one possible implementation, the first card message may include a suggested operation for sending a message. After the user selects the suggested operation option for sending a message of the first card message and enters the content to be sent, the first terminal device sends the first message to the message platform. The first message may include a second identifier of the set-top box, and the second identifier may be added to the first message based on the suggested operation for sending a message, such as in the first content.

[0205] S702: The MaaP device sends a first message to the message subsystem.

[0206] Accordingly, the message subsystem receives a first message from the MaaP device.

[0207] Optionally, the messaging subsystem may send an HTTP status code 200 OK to the MaaP device.

[0208] S703: The message subsystem sends the second content to the set-top box.

[0209] Correspondingly, the set-top box receives the second content from the message subsystem, wherein the second content corresponds to the first content, or the second content may be determined based on the first content.

[0210] In a possible implementation, the message subsystem saves the corresponding relationship, and the message subsystem can determine the third identifier based on the first identifier. Wherein, the first identifier is the same as the third identifier or the first identifier is constructed, determined, or generated based on the third identifier. The message subsystem can determine the corresponding second identifier based on the saved corresponding relationship between the second identifier and the third identifier and the determined third identifier, so that the message subsystem can determine the corresponding set-top box and send the second content to the set-top box. The message subsystem sends the first content to the set-top box as the second content.

[0211] In another possible implementation, the first content of the first message includes a second identifier, and the message subsystem can determine the corresponding set-top box based on the second identifier and send the second content to the set-top box. The message subsystem sends the first content to the set-top box as the second content or deletes the second identifier included in the first content and sends it to the set-top box as the second content.

[0212] Optionally, the set-top box may send a response message to the message subsystem, where the response message may indicate that the second content has been received.

[0213] based on Figure 7 In the illustrated embodiment, the RCS message intercommunication between the set-top box and the first terminal device can be achieved through the message subsystem.

[0214] Figure 7In the illustrated embodiment, due to the different types of the first message, the second content is also different. In one possible case, the first message may be a text message. When the first message is a text message, the second content may be the first content or modified based on the first content, such as deleting the second identifier in the first content. In another possible case, the first message may be a file transfer message. When the first message is a file transfer message, the first content may include a first hypertext link, through which the second content may be obtained. Figure 8 Make an introduction.

[0215] See also Figure 8 , which is an exemplary flowchart of a message transmission method provided in an embodiment of the present application, may include the following operations.

[0216] S801: The first terminal device sends second content to the multimedia content storage device.

[0217] Correspondingly, the multimedia content storage device receives the second content from the first terminal device.

[0218] For example, the first terminal device may send an HTTP submit data (POST) message to the multimedia content storage device, and the HTTP POST message may carry the second content.

[0219] S802: The multimedia content storage device sends a first hypertext link to the first terminal device.

[0220] Correspondingly, the first terminal device receives the first hypertext link from the multimedia content storage device.

[0221] The first hypertext link may be an address link for storing the second content. Exemplarily, the multimedia content storage device may send an HTTP status code 200 OK to the first terminal device, and carry the first hypertext link.

[0222] S803 to S804 can be implemented with reference to S701 and S702, except that the message content includes a first hypertext link.

[0227] Correspondingly, the message subsystem receives the second content from the multimedia content storage device. Exemplarily, the multimedia content storage device may send an HTTP status code 200 OK to the message subsystem, and carry the second content.

[0228] S807 is implemented with reference to S703.

[0229] based on Figure 8 In the illustrated embodiment, the set-top box can receive the file of the first terminal device through the message subsystem.

[0230] In an embodiment of the present application, the first card message can also be shared with other terminal devices. For example, the first card message can include a sharing card suggestion operation option. The first terminal device can generate a second card message based on the first card message based on the sharing card suggestion operation and then share it with other terminal devices, such as the second terminal device. The second terminal device can send an RCS message to the set-top box based on the shared second card message. Since the second identifier of the set-top box is automatically filled in when the RCS message is sent based on the card message, the message subsystem can determine the corresponding set-top box based on the second identifier. Even if the message subsystem does not save the binding relationship between the set-top box and the terminal device, the RCS message can be sent to the corresponding set-top box. It can be understood that the operation of the second terminal device sending an RCS message to the set-top box based on the card message can refer to Figure 7 and Figure 8 The repetitive parts will not be repeated here.

[0231] In the embodiment of the present application, the set-top box may also send an RCS message to the first terminal device. Fig. 9 Provide explanation.

[0232] See also Fig. 9 , which is an exemplary flowchart of a message transmission method provided in an embodiment of the present application, may include the following operations.

[0233] S901: The set-top box sends a fifth message to the message subsystem.

[0234] Correspondingly, the message subsystem receives the fifth message from the set-top box.

[0235] Among them, the fifth message may include a fourth identifier and a fourth content. Among them, the fourth identifier may correspond to the third identifier or the fourth identifier may be determined based on the third identifier. For example, the fourth identifier is the same as the third identifier, such as the fourth identifier and the third identifier are both the SIP URI of the first terminal device. For another example, the fourth identifier is constructed based on the third identifier, such as the third identifier is an MSISDN, and the fourth identifier is a SIP URI determined based on the third identifier. The message subsystem can deduce each other based on the third identifier and the fourth identifier. For example, the message subsystem can determine the fourth identifier based on the third identifier, or determine the third identifier based on the fourth identifier. Exemplarily, the fourth identifier is the destination address field of the fifth message, and the source address field of the fifth message may be the SIP URI determined by the second identifier of the set-top box.

[0236] Optionally, the message subsystem sends a response message to the set-top box to indicate that the fifth message has been received.

[0237] S902: The message subsystem sends a sixth message to the MaaP device.

[0238] Correspondingly, the MaaP device receives the sixth message from the message subsystem.

[0239] The sixth message may include a fourth identifier and a fifth content, and the fifth content corresponds to the fourth content, or the fifth content is determined according to the fourth content. The source address field of the sixth message may be the SIP URI of the message subsystem. Optionally, the MaaP device may send an HTTP status code 200OK to the message subsystem.
