Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communication technology, in particular to a transmission method, device, equipment and readable storage medium. BACKGROUND

[0002] The 5th-Generation (5G) message is an upgrade of the operator's basic communication service, which provides a rich media message service based on the terminal's original file transmission technology (hereinafter referred to as file transmission). At present, the 5G message solution refers to the international standard of the Rich Communication Suite (RCS) series of the Global System for Mobile Communications Association (GSMA), and the implementation of the file transmission service function is mainly divided into two types:

[0003] One is to transmit based on the Message Session Relay Protocol (MSRP) protocol in the Large Message Mode;

[0004] The other is to transmit based on the Hyper Text Transfer Protocol (HTTP) protocol combined with the Pager Mode Message (hereinafter referred to as the Session Initiation Protocol (SIP) message (Message) signaling).

[0005] Since the first way needs to establish an MSRP tunnel through the SIP INVITE for media negotiation between the main receivers, and the second way needs to pay additional signaling overhead, at present, whether from the international standard or our own technical solution, the file transmission is implemented based on the HTTP protocol combined with the Pager Mode Message, and the specific implementation way is as follows:

[0006] (1) The sender first uploads the file based on the HTTP protocol.

[0007] Referring to Figure 1 , the process is as follows:

[0008] 1-3) The sender client (UE A) sends an HTTPS POST empty request to the file server (or referred to as the content server), and the file server returns a 401 / 511 response to the sender client to perform a general bootstrapping architecture (GBA) authentication;

[0009] 4-6) The UE A sends an HTTPS POST request to the file server to perform a file uploading process, including a tunnel identifier (TID) uniquely identifying a file transmission, a thumbnail, and a file, and the file server returns a file storage path to the UE A after completing the transmission.

[0010] (2) The UE A sends an address to the receiver client UE B (not shown in the figure) through a SIP Message signaling.

[0011] Referring to Figure 2 , the flow is explained as follows:

[0012] 1-12) The UE A sends a SIP Message signaling to the UE B;

[0013] 13-24) The UE B returns a 200 OK after receiving the message, triggering a message receipt to be sent to the UE A.

[0014] (3) The receiver downloads a file content using an HTTP protocol according to a SIP message content.

[0015] Referring to Figure 3 , the flow is explained as follows:

[0016] 1-3) The UE B obtains a thumbnail link through a SIP Message, and the terminal automatically downloads the thumbnail;

[0017] 4-7) The UE B actively clicks the thumbnail to start downloading the file;

[0018] 8-9) After the file transmission is completed, the UE B sends a delivery report to the UE A as needed.

[0019] The prior art has the following problems:

[0020] 1. More signaling interaction: the sender terminal (UE A) of the above scheme needs to upload the file through HTTP first, and after the uploading is completed, the platform generates a file uniform resource locator (URL) address and returns it to the sender terminal, and the sender terminal needs to encapsulate the SIP message again to send the URL address to the receiver, the whole process involves more signaling interaction between the terminal and the platform, and the data overhead is large;

[0021] 2. Complex terminal implementation: the sender terminal needs to use different protocols for multiple signaling encapsulation and signaling analysis, which is high in processing complexity for the terminal itself;

[0022] 3. General business experience: the sender terminal needs to upload the file, and the platform returns the file URL address, and then sends the URL address to the receiver, if any step of signaling has problems such as packet loss or delay, etc., the business experience of the whole file transmission will be affected. SUMMARY

[0065] Referring to Figure 4 In the embodiments of the present application, a transmission method is provided, and the execution subject of the method can be a file server. The specific steps include steps 401 and 402.

[0066] Step 401: receiving a first message from a sending end, the first message including a file that needs to be sent by the sending end to a receiving end and related information for the file server to encapsulate a SIP message;

[0067] It can be understood that the above-mentioned file can be a picture, audio or video, etc.

[0068] Step 402: encapsulating a SIP message according to the first message, and sending the SIP message to the receiving end, the SIP message including an address where the file is stored in the file server.

[0069] In an embodiment of the present application, the method further includes:

[0070] receiving a download request from the receiving end, the download request being used for the receiving end to request to download the file from the file server.

[0071] In an embodiment of the present application, the step of sending the SIP message to the receiving end comprises:

[0072] sending the SIP message to a message server (such as a 5G message center), the SIP message further comprising address information of the receiving end, and sending the SIP message to the receiving end through the message server.

[0073] In an embodiment of the present application, the first message is an HTTP request message, such as an HTTPS POST message.

[0074] In an embodiment of the present application, the file server is configured to perform one or more of the following:

[0075] (1) storing the file uploaded by the sending end and generating an address (such as a URL address) of the file;

[0076] (2) parsing the HTTP request message carried by the file uploaded by the sending end and encapsulating at least part of the content into a SIP message;

[0077] (3) forwarding the SIP message to the message server.

[0078] In an embodiment of the present application, the message server is configured to forward the SIP message to the receiving end, and the receiving end obtains the file through the address of the file carried in the SIP message.

[0079] In an embodiment of the present application, the HTTP request message can further carry information of the sending end and / or the receiving end.

[0080] In an embodiment of the present application, the following beneficial effects are achieved:

[0081] (1) reducing signaling interaction between the sending end and the file server: the sending end carries the sending end / receiving end information when uploading the file, the file server generates a storage address of the file and encapsulates a SIP message to send to the message server after the uploading is completed, and the message server sends the file to the receiving end, thereby solving the problem of high signaling interaction and large data overhead between the terminal and the platform;

[0082] (2) reducing the implementation complexity of the sending end: the sending end does not need to store the file by monitoring and analyzing the HTTP signaling, nor does it need to encapsulate an additional SIP message, thereby greatly reducing the processing complexity of the sending end itself;

[0083] (3) improving the service experience: since the signaling interaction between the sending end and the file server over the air interface is reduced, theoretically, the problem of packet loss, delay and the like caused by network factors is greatly reduced, and the efficiency of file transmission message interaction is improved.

[0084] Referring to Figure 5 The embodiment of the present application provides a transmission method, and the execution subject of the method can be a sending end, and the specific steps include the following steps.

[0085] Step 501: sending a first message to a file server, wherein the first message includes a file that needs to be sent by the sending end to a receiving end and related information used for the file server to encapsulate a SIP message.

[0086] In the embodiment of the present application, the sending end can realize the optimization of the rich media message through one signaling, and the multiple signaling interactions are avoided.

[0087] In one embodiment of the present application, the method further includes the following steps.

[0088] Step 502: receiving a second message from the file server, wherein the second message indicates that the file uploading is successful.

[0089] In the embodiment of the present application, the following beneficial effects are achieved.

[0090] (1) The signaling interaction between the sending end and the file server is reduced: the sending end carries the sender / receiver information when uploading the file, and the file server generates the storage address of the file and encapsulates the SIP message to send to the message server after the uploading is completed, and the message server sends the file to the receiving end, thereby solving the problem of the large signaling interaction and data overhead between the terminal and the platform;

[0091] (2) The implementation complexity of the sending end is reduced: the sending end does not need to obtain the storage of the file by monitoring and analyzing the HTTP signaling, and does not need to additionally encapsulate the SIP message, thereby greatly reducing the processing complexity of the sending end itself;

[0092] (3) The service experience is improved: the signaling interaction between the sending end and the file server in the air interface is reduced, and theoretically, the problems of packet loss and delay caused by network factors are greatly reduced, and the efficiency of the file transmission message interaction is improved.

[0093] Referring to Figure 6 , the specific steps are as follows.

[0094] Step 1: a sender User1 selects media content to be sent in a terminal locally;

[0095] Steps 2-3: the sender User1 performs GBA authentication, and uploads to the file server through HTTPS POST, and the server returns HTTPS 200OK to the sender User1 after the uploading is successful.

[0096] Step 4: The file server encapsulates a SIP message (text message) carrying the address of the file storage, and sends the message to the 5G message center (5GMC) to notify the message server;

[0097] Steps 5-7: The 5G message center (5GMC) sends the message to the recipient User2. After receiving the message, the recipient User2 replies with a 200 OK to the message server, and parses the message content. If it is a file transmission message, the recipient User2 starts the HTTPS GET to download the media content;

[0098] Steps 8-9: The recipient User2 successfully downloads the media content and displays the picture, video or audio, etc.

[0099] Steps 10-13: After successful download, the recipient User2 sends a message receipt.

[0100] After the sender User1 uploads the file, there is no additional signaling interaction with the message server, so the file storage address is encapsulated into a SIP message by the file server and sent to the recipient User2 after the media content upload is completed. This greatly reduces the additional signaling interaction, improves efficiency and reduces the possibility of packet loss.

[0101] Referring to Figure 7 The embodiment of the present application provides a transmission device applied to a file server, and the device 700 comprises:

[0102] A receiving module 701 is configured to receive a first message from a sending end, wherein the first message comprises a file to be sent by the sending end to a receiving end and related information for encapsulating a SIP message by the file server.
