Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0036] The character " / " in this article generally indicates that the contextual objects are an "or" relationship. For example, A / B can be understood as A or B.

[0037] The terms "first" and "second" in the specification and claims of the present application are used to distinguish different objects, rather than to describe a specific order of objects. For example, the first edge service node and the second edge service node are used to distinguish different edge service nodes, ra...

Abstract

Disclosed are a data transmission method, apparatus and system, an electronic device and a storage medium, which relate to the field of communications, and are used for solving the problem of low message data security when a wireless terminal performs message transmission with a core network in the prior art, comprising: a user terminal sending a data message to a user plane function network element through a base station; the user plane function network element determines an encryption mode and a destination IP address of the data message; and the user plane function network element sends the data message to the destination IP address. The method and the device are used for encrypted message transmission between the wireless terminal and the core network.

Description

technical field [0001] The present application relates to the communication field, and in particular to a data transmission method, device, system, electronic equipment and storage medium. Background technique [0002] At present, after the wireless terminal establishes a bearer with the core network through the base station, when the wireless terminal transmits data packets on the bearer, all data packets sent and received are transmitted in plain text. The message data is transmitted in the wireless channel and the bearer network in clear text, which will lead to security problems such as message data leakage, data tampering, traffic hijacking, phishing attacks, etc., as long as the network sniffing equipment and some technical means can be used to restore the message. The content of the text is very insecure. [0003] The solution in the prior art is that the wireless terminal establishes a bearer with the core network through the base station, and transmits data packets...
