[0062] 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.

[0063] The information processing method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the user terminal (UE) 102 and the operator's satellite-to-ground intercommunication platform 106 can communicate with the IMS network 104. In actual applications, the IMS network 104 responds to the user terminal 102 registering with the IMS network 104 for the first time, and sends a user registration status notification to the operator's satellite-to-ground intercommunication platform 106; the user registration status notification is used to trigger the operator's satellite-to-ground intercommunication platform 106 to convert the short message that the user terminal 102 has not yet received through the satellite into a short message; the IMS network 104 forwards the short message returned by the operator's satellite-to-ground intercommunication platform 106 to the user terminal 102. Among them, the user terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers and portable wearable devices, and the portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. Among them, the IMS network can refer to a mobile IMS (IP Multimedia Subsystem) network. Among them, the operator's satellite-ground intercommunication platform refers to an interconnection platform established between ground operators and satellite communication systems.

[0064] In an exemplary embodiment, Figure 2 As shown, an information processing method is provided, which is applied to Figure 1 The IMS network 104 in FIG. 1 is taken as an example to illustrate, including the following steps S202 to S203. Among them:

[0065] Step S202, in response to the user terminal registering with the IMS network for the first time, a user registration status notification is sent to the operator's satellite-ground intercommunication platform.

[0066] The user registration status notification may refer to a notification used to inform the operator of the registration status of the user terminal of the satellite-ground intercommunication platform.

[0067] Among them, the user registration status notification is used to trigger the operator's satellite-to-ground intercommunication platform to convert the short message that the user terminal has not yet received through the satellite into a short message.

[0068] In a specific implementation, when a user terminal registers to an IMS network, the IMS network can detect whether the user terminal is registering to the IMS network for the first time; if the user terminal is registering to the IMS network for the first time, the IMS network can respond to the trigger condition that the user terminal registers to the IMS network for the first time and send the above-mentioned user registration status notification to the operator's satellite-ground intercommunication platform.

[0069] After receiving the user registration status notification, the operator's satellite-to-ground intercommunication platform can query whether there are short messages on the operator's satellite-to-ground intercommunication platform that have not been received by the Beidou user of the user terminal based on the user identifier carried in the user registration status notification.

[0070] In the case where there are short messages in the operator's satellite-to-ground intercommunication platform that have not been received by the user terminal via the satellite, the operator's satellite-to-ground intercommunication platform can convert the unreceived short messages into short messages; specifically, the operator's satellite-to-ground intercommunication platform can obtain a pre-configured short message template; then, the operator's satellite-to-ground intercommunication platform can fill the message content in the short message into the pre-configured short message template to obtain the above-mentioned short message. After the operator's satellite-to-ground intercommunication platform obtains the short message, the operator's satellite-to-ground intercommunication platform returns the short message to the IMS network. In addition, the operator's satellite-to-ground intercommunication platform can delete the short message stored in the operator's satellite-to-ground intercommunication platform to reduce the occupation of the data storage space of the operator's satellite-to-ground intercommunication platform.

[0071] Step S204: forwarding the short message returned by the operator's satellite-ground intercommunication platform to the user terminal.

[0072] In the specific implementation, after the IMS network obtains the short message returned by the operator's satellite-to-ground intercommunication platform, the IMS network sends the short message to the user terminal. Specifically, the operator's satellite-to-ground intercommunication platform can send a short message downlink message to the SIP (Session Initiation Protocol) interface intercommunication platform; through the short message downlink message, the SIP interface intercommunication platform is instructed to convert the short message into a SIP message, and the IMS network sends the SIP message to the user terminal, so as to forward the short message returned by the operator's satellite-to-ground intercommunication platform to the user terminal.

[0073] In the above information processing method, the IMS network sends a user registration status notification to the operator's satellite-to-ground intercommunication platform in response to the trigger condition of the user terminal's first registration to the IMS network, thereby triggering the operator's satellite-to-ground intercommunication platform to query whether there is a short message that the user terminal has not yet received through the satellite through the user registration status notification, and if there is a short message that the user terminal has not yet received through the satellite, the short message is converted into a short message, and the short message is forwarded to the user terminal through the IMS network, so that when the user terminal leaves the satellite network and accesses the IMS network, the operator's satellite-to-ground intercommunication platform can be promptly and effectively notified that the user terminal has currently left the satellite network, so as to trigger the operator's satellite-to-ground intercommunication platform to promptly convert the user's unreceived short messages that have been stranded on the operator's satellite-to-ground intercommunication platform into short messages, and promptly forward the user's unreceived short messages to the user terminal through the IMS network, thereby effectively improving the timeliness of the user terminal obtaining short messages.

[0074] In an exemplary embodiment, in response to a user terminal registering with an IMS network for the first time, sending a user registration status notification to an operator's satellite-to-ground intercommunication platform includes: receiving a user registration request sent by the user terminal, and identifying a registration type of the user registration request; when the registration type of the user registration request is a first registration, sending a user registration status notification to the operator's satellite-to-ground intercommunication platform via a SIP interface intercommunication platform.

[0075] In a specific implementation, the IMS network sends a user registration status notification to the operator's satellite-ground intercommunication platform in response to the user terminal registering with the IMS network for the first time, specifically including: Figure 3 In the process of user terminal registering with the IMS network, the user terminal can send a user registration request (Register) to the P-CSCF (Proxy- Call Session Control Function) entity or BAC (Border Access Controller) of the IMS network; the P-CSCF entity / BAC receives the user registration request sent by the user terminal and identifies the registration type of the user registration request.

[0076] In some embodiments, the IMS network includes a P-CSCF entity, receiving a user registration request sent by a user terminal, and determining a registration type of the user registration request, including: in response to the user registration request, querying whether the P-CSCF entity stores user registration information of the user terminal;

[0077] If the P-CSCF entity stores the user registration information and the user registration information is within the registration validity period, the registration type of the user registration request is determined to be re-registration;

[0078] If the P-CSCF entity does not store the user registration information, it is determined that the registration type of the user registration request is the first registration;

[0079] If the P-CSCF entity stores user registration information, but the user registration information exceeds the registration validity period, the registration type of the user registration request is determined to be the first registration;

[0080] Specifically, the P-CSCF entity / BAC is configured with a registration type identification module, through which it is determined whether the user information (i.e., user registration information) of the user terminal is currently stored; if the user registration information is stored and the user registration information is currently within the registration validity period, the registration type identification module determines that the registration type of the user registration request is not the first registration;

[0081] If the user registration information is not stored, the registration type identification module determines that the registration type of the user registration request is the first registration. Alternatively, if the user registration information is stored but the user registration information exceeds the registration validity period (i.e., the user registration information has expired), the registration type identification module determines that the registration type of the user registration request is the first registration. If the registration type of the user registration request is the first registration, the IMS network can send a user registration status notification to the operator's satellite-ground intercommunication platform through the SIP interface intercommunication platform.

[0082] The technical solution of this embodiment, by receiving a user registration request sent by a user terminal, identifies the registration type of the user registration request, and only sends a user registration status notification to the operator's satellite-ground intercommunication platform through the SIP interface intercommunication platform when the registration type of the user registration request is the first registration, thereby achieving the situation where the uncollected short messages stranded on the operator's satellite-ground intercommunication platform are pulled when the user terminal registers to the IMS network for the first time, and achieving the periodic registration of the user terminal in the subsequent periodic registration of the IMS network without notifying the operator's satellite-ground intercommunication platform of the registration status of the user terminal, thereby avoiding multiple wastes of equipment resources and network resources.

[0083] In an exemplary embodiment, sending a user registration status notification to an operator's satellite-to-ground intercommunication platform via a SIP interface intercommunication platform includes: sending a user registration request to an S-CSCF entity; the S-CSCF entity is used to complete an initial registration process for a user terminal and generate a third-party registration request; sending a third-party registration request to the SIP interface intercommunication platform via the S-CSCF entity; the third-party registration request is used to trigger the SIP interface intercommunication platform to send a user registration status notification to the operator's satellite-to-ground intercommunication platform.

[0084] The IMS network includes an S-CSCF (Serving-Call Session Control Function) entity.

[0085] In the specific implementation, the IMS network sends the user registration status notification to the operator's satellite-to-ground intercommunication platform through the SIP interface intercommunication platform, specifically including: Figure 3 , when the registration type identification module of the P-CSCF entity / BAC determines that the registration type of the user registration request is the first registration, the P-CSCF entity / BAC can directly send the user registration request to the S-CSCF entity; after the S-CSCF entity obtains the user registration request, the S-CSCF entity can control the execution of the initial registration process of the user terminal and return a response to the user terminal to complete the initial registration process of the user terminal.

[0086] In actual applications, the S-CSCF entity is configured with a service trigger module, which is used to query the user service trigger initial filtering rule (iFC), and based on the user service trigger initial filtering rule, determine whether the current conditions for sending a third-party registration request to the SIP interface intercommunication platform are met. In response to the conditions for sending a third-party registration request to the SIP interface intercommunication platform being met, the service trigger module generates a third-party registration request and sends the third-party registration request to the SIP interface intercommunication platform.

[0087] It should be noted that the initial filtering rules have a priority order, and the S-CSCF entity can sort the services according to the initial filtering rules and send the services to different ASs (Application Servers).

[0088] In actual applications, the SIP interface intercommunication platform is configured with a user status synchronization module. After receiving a third-party registration request, the user status synchronization module can respond to the third-party registration request and send a user registration status notification to the operator's satellite-to-ground intercommunication platform.

[0089] In actual applications, the operator's satellite-to-ground intercommunication platform is configured with a stranded short message processing module. After receiving the user registration status notification, the stranded short message processing module can query whether there are short messages on the operator's satellite-to-ground intercommunication platform that have not been received by the Beidou user of the user terminal based on the user identifier carried in the user registration status notification.

[0090] In the case that there are short messages that the user terminal has not received through the satellite, the retained short message processing module can convert the unreceived short messages into short messages; after the retained short message processing module obtains the short message, it returns the short message to the IMS network.

[0091] The stranded short message processing module can send a short message to a SIP (Session Initiation Protocol) interface intercommunication platform; through the short message sending message, the SIP interface intercommunication platform is instructed to convert the short message into a SIP message, and the IMS network sends the SIP message to the user terminal.

[0092] The technical solution of this embodiment sends a user registration request to the S-CSCF entity to trigger the S-CSCF entity to complete the initial registration process of the user terminal, and triggers the S-CSCF entity to meet the conditions for sending a third-party registration request to the SIP interface intercommunication platform, thereby achieving timely and efficient sending of user registration status notifications to the operator's satellite-to-ground intercommunication platform through the S-CSCF entity controlling the SIP interface intercommunication platform.

[0093] In an exemplary embodiment, when the registration type of the user registration request is re-registration, the method also includes: adding a re-registration identifier in the user registration request; sending the user registration request with the identifier to the S-CSCF entity; the S-CSCF entity is used to complete the re-registration process of the user terminal, and in response to the re-registration identifier, no longer sends a third-party registration request to the SIP interface intercommunication platform.

[0094] The re-registration identifier is used to identify that the user registration request is sent by the user terminal to periodically re-register with the IMS network.

[0095] For specific implementation, see Figure 4 , the IMS network can determine whether the user information of the user terminal is currently stored through the registration type identification module; if the user information of the user terminal is stored, the registration type identification module determines that the registration type of the user registration request is periodic re-registration; if the registration type of the user registration request is re-registration, the registration type identification module can add a re-registration identifier to the user registration request, and use the re-registration identifier to identify that the user registration request is issued by the user terminal when the user terminal periodically re-registers the IMS network.

[0096] Specifically, the user registration request is a Register message, and the registration type identification module may carry a parameter "per" in the Contact header field in the Register message to identify that the user registration request is a re-registration.

[0097] Then, the P-CSCF entity / BAC can send the identified user registration request to the S-CSCF entity; after the S-CSCF entity obtains the identified user registration request, the S-CSCF entity can control the execution of the re-registration process of the user terminal and return a response to the user terminal to complete the re-registration process of the user terminal.

[0098] Optionally, the S-CSCF entity receives the user registration request after the identifier, and the S-CSCF entity queries the initial filtering rules; the initial filtering rules are configured with exception conditions; the exception conditions record that when the user registration request contains a re-registration identifier, it is determined that the condition for sending a third-party registration request to the SIP interface intercommunication platform is not met; in response to the S-CSCF entity determining that the exception condition is met, the S-CSCF entity is not triggered to send a third-party registration request to the SIP interface intercommunication platform.

[0099] In actual applications, the service trigger module of the S-CSCF entity is used to query the initial filtering rules. In actual applications, the initial filtering rules are added with service trigger exception conditions, and the exception conditions record that when the user registration request includes a re-registration identifier, it is determined that the conditions for sending a third-party registration request to the SIP interface intercommunication platform are not met.

[0100] Specifically, the exception condition is that the Contact header field of the Register message contains the parameter "per", which is determined to be inconsistent with the condition for sending a third-party registration request to the SIP interface intercommunication platform.

[0101] In actual applications, when the service trigger module of the S-CSCF entity determines that the exception condition is currently met, it will no longer send a third-party registration request to the SIP interface intercommunication platform.

[0102] The technical solution of this embodiment, when the registration type of the user registration request is re-registration, by adding a re-registration identifier in the user registration request, it is possible to effectively identify through the re-registration identifier that the user registration request is a registration request sent by the user terminal when the user terminal periodically re-registers with the IMS network, and then effectively inform the S-CSCF entity not to send a third-party registration request to the SIP interface intercommunication platform, so that the subsequent periodic registration of the user terminal with the IMS network no longer notifies the operator's satellite-to-ground intercommunication platform of the registration status of the user terminal, thereby avoiding multiple wastes of equipment resources and network resources.

[0103] In an exemplary embodiment, a user registration status notification is sent to an operator's satellite-to-ground intercommunication platform via a SIP interface intercommunication platform, including: recording address information of an S-CSCF entity and generating a user registration status notification; the user registration status notification includes a user identifier of a user terminal; when an HTTP communication connection is established between the SIP interface intercommunication platform and the operator's satellite-to-ground intercommunication platform, the user registration status notification is sent to the operator's satellite-to-ground intercommunication platform; wherein the operator's satellite-to-ground intercommunication platform is used to query whether there is a retained short message associated with the user identifier; a retained short message is a short message that has not yet been received by the user terminal via a satellite.

[0104] For specific implementation, please refer to Figure 3, in the process of the IMS network sending the user registration status notification to the operator's satellite-to-ground intercommunication platform through the SIP interface intercommunication platform, the user status synchronization module of the SIP interface intercommunication platform can record the address information of the S-CSCF entity and generate a user registration status notification including the user identifier of the user terminal. Then, the user status synchronization module sends the user registration status notification to the operator's satellite-to-ground intercommunication platform through the HTTP protocol. Specifically, the SIP interface intercommunication platform can establish an HTTP communication connection with the operator's satellite-to-ground intercommunication platform; when the SIP interface intercommunication platform establishes an HTTP communication connection with the operator's satellite-to-ground intercommunication platform, the user status synchronization module sends the user registration status notification to the operator's satellite-to-ground intercommunication platform.

[0105] After the stranded short message processing module of the operator's satellite-to-ground intercommunication platform receives the user registration status notification sent by the SIP interface intercommunication platform, the stranded short message processing module inquires whether there is a stranded short message associated with the user ID, and the stranded short message is a short message that the user terminal has not yet received through the satellite. If there is a stranded short message associated with the user ID, the stranded short message processing module converts the stranded short message into a short message and sends the short message to the SIP interface intercommunication platform through the http protocol.

[0106] Optionally, forwarding the short message returned by the operator's satellite-ground intercommunication platform to the user terminal includes: converting the short message into a corresponding SIP message through the SIP interface intercommunication platform; sending the SIP message to the S-CSCF entity according to the address information, so that the IMS network forwards the SIP message to the user terminal.

[0107] For specific implementation, please refer to Figure 3 After the user status synchronization module of the SIP interface intercommunication platform receives the short message sent by the operator's satellite-to-ground intercommunication platform, the user status synchronization module can convert the short message forwarded by the short message sending message request into a corresponding SIP message (Message); then, the user status synchronization module sends the SIP message to the S-CSCF entity that matches the previously recorded S-CSCF entity address information. The S-CSCF entity sends the SIP message to the P-CSCF entity / BAC; the P-CSCF entity / BAC sends the SIP message to the user terminal, thereby enabling the IMS network to forward the SIP message to the user terminal.

[0108] In an exemplary embodiment, Figure 5 As shown, an information processing method is provided, which is applied to Figure 1 The operator satellite-to-ground intercommunication platform 106 in FIG. 1 is used as an example to illustrate the method, which includes the following steps S502 to S504. Among them:

[0109] Step S502, responding to the user registration status notification of the user terminal, querying the short messages that the user terminal has not yet received via the satellite; the user registration status notification indicates that the user terminal is registering to the IMS network for the first time.

[0110] Step S504: convert the short message into a short message, and send the short message to the user terminal through the IMS network.

[0111] It should be noted that the specific limitations of the above steps can be found in the specific limitations of an information processing method above, which will not be repeated here.

[0112] In the above information processing method, the IMS network sends a user registration status notification to the operator's satellite-to-ground intercommunication platform in response to the trigger condition of the user terminal's first registration to the IMS network, thereby triggering the operator's satellite-to-ground intercommunication platform to query whether there is a short message that the user terminal has not yet received through the satellite through the user registration status notification, and if there is a short message that the user terminal has not yet received through the satellite, the short message is converted into a short message, and the short message is forwarded to the user terminal through the IMS network, so that when the user terminal leaves the satellite network and accesses the IMS network, the operator's satellite-to-ground intercommunication platform can be promptly and effectively notified that the user terminal has currently left the satellite network, so as to trigger the operator's satellite-to-ground intercommunication platform to promptly convert the user's unreceived short messages that have been stranded on the operator's satellite-to-ground intercommunication platform into short messages, and promptly forward the user's unreceived short messages to the user terminal through the IMS network, thereby effectively improving the timeliness of the user terminal obtaining short messages.

[0113] In another embodiment, Figure 6 As shown, an information processing method is provided, which is applied to Figure 1 Taking the IMS network 104 in FIG. 1 as an example, the method includes the following steps:

[0114] Step S602: receiving a user registration request sent by a user terminal through a P-CSCF entity / BAC, and identifying a registration type of the user registration request;

[0115] Step S604: When the registration type of the user registration request is the first registration, the user registration request is sent to the S-CSCF entity through the P-CSCF entity / BAC;

[0116] Step S606, completing the initial registration process of the user terminal through the S-CSCF entity, sending a third-party registration request to the SIP interface intercommunication platform; the third-party registration request is used to trigger the SIP interface intercommunication platform to send a user registration status notification to the operator's satellite-to-ground intercommunication platform; the user registration status notification is used to trigger the operator's satellite-to-ground intercommunication platform to convert the short message that the user terminal has not yet received through the satellite into a short message;

[0117] Step S608, receiving the short message returned by the operator's satellite-to-ground intercommunication platform through the SIP interface intercommunication platform, and converting the short message into a corresponding SIP message;

[0118] Step S610: Send the SIP message to the S-CSCF entity through the SIP interface intercommunication platform, so that the IMS network forwards the SIP message to the user terminal.
