Description

Transmission method, device, equipment and readable storage medium

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a transmission method, a transmission device, transmission equipment and a readable storage medium.

Background

The fifth Generation mobile communication technology (5 th-Generation, 5G) message is an upgrade of the carrier's basic communication service, and is based on a terminal native provisioning rich media message (implemented by file transfer technology, hereinafter expressed in file transfer) service. At present, the 5G message solution is formulated by referring to international standards of the Rich Communication Suite (RCS) series of Global System for Mobile Communications Association (GSMA), and the implementation of the file transfer service function is mainly divided into two types:

one is based on Message Session Relay Protocol (MSRP) Protocol and adopts Large Message Mode (Large Message Mode) Mode for transmission;

the other is based on a Hyper Text Transfer Protocol (HTTP) Protocol and transmitted in combination with a paging Mode Message (hereinafter, expressed in a Session Initiation Protocol (SIP) Message signaling).

Because the first Mode needs to additionally perform media negotiation between the main receiver and the receiver through SIP INVITE (INVITE) to establish the MSRP tunnel, and extra signaling overhead is needed compared with the second Mode, the current technical scheme of file transmission, whether from the international standard or the company, is realized by adopting an HTTP-based protocol and combining a Pager model Message Mode, and the specific implementation Mode is as follows:

(1) The sender uploads the file based on the HTTP protocol.

Referring to fig. 1, the process is illustrated as follows:

1-3) the sender client (UE A) sends an HTTPS POST empty request to a file server (or called a content server), the file server returns a 401/511 response to the sender client, and General Bootstrapping Architecture (GBA) authentication is carried out;

4-6) the UE A sends an HTTPS POST request to the file server to perform file uploading processing, wherein the HTTPS POST request comprises a Tunnel Identifier (TID) for uniquely identifying file transmission, a thumbnail and a file, and the file server returns a file storage path to the UE A after transmission is completed.

(2) UE a sends the address to the recipient client UE B (not shown in the figure) by SIP Message signaling.

Referring to fig. 2, the flow is illustrated as follows:

1-12) UE A sends SIP Message signaling to UE B;

13-24) the UE B returns 200OK after receiving the message, and triggers the message to return receipt and send to the UE A.

(3) And the receiver downloads the file content by using an HTTP (hyper text transport protocol) according to the SIP message content.

Referring to fig. 3, the flow is illustrated as follows:

1-3) the UE B obtains a thumbnail link of the file through the SIP Message, and the terminal automatically downloads the thumbnail;

4-7) the UE B actively clicks the thumbnail to start downloading the file;

8-9) after the file transmission is finished, the UE B sends a delivery report to the UE A according to the requirement.

The prior art has the following problems:

1. more signaling interaction: according to the scheme, a sender terminal (UE A) needs to upload a file through HTTP, after uploading is completed, a platform generates a Uniform Resource Locator (URL) address of the file and returns the URL address to the sender terminal, the sender terminal needs to encapsulate an SIP Message again and sends the URL address to a receiver, and the whole process involves more signaling interaction between the terminal and the platform and has high data overhead;

2. the terminal is complex to realize: the sender terminal needs to use different protocols to perform signaling encapsulation and signaling analysis for many times, and the processing complexity of the terminal is high;

3. the service experience is general: after the file is uploaded, the platform replies the file URL address to the sender terminal, and then the URL address can be sent to the receiver, if any signaling of the step is in a problem, such as packet loss or delay, the service experience of the whole file transmission can be affected.
