Abstract

The embodiment of the invention discloses a data transmission method, system and device, which are applied to the technical field of communication. In the embodiment of the invention, after receiving an access request, a PCRF (Policy and Charging Rules Function) entity generates encryption information corresponding a user identification in the access request, and sends the encryption information to a gateway to indicate that the gateway encrypts transmission data corresponding to the user identification according to the encryption information. The invention provides a safety protection strategy of the transmission data, so that the user can customize a corresponding safety strategy service according to the demand, and encrypts the data transmitted by a terminal device, so that the purpose of protecting the transmission data is achieved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data transmission method, system and equipment. Background technique [0002] With the continuous evolution of mobile communication networks, the proportion of multi-mode and intelligent terminals is gradually increasing, the carrying capacity of data services has been greatly improved, and various applications are emerging in an endless stream, followed by increasingly prominent network security issues. How to prevent user data leakage in the network has become a hot security issue. [0003] The existing mobile communication network includes a policy and charging control (Policy and Charging Control, PCC) architecture, which is mainly based on the packet domain to implement service policy control, specifically, grouping is performed according to user levels, different times, different locations, and different service types. Data service quality of service (Quality of S...
