Embodiment Construction

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] figure 2 A flow chart showing a safety function control method according to an embodiment of the present invention includes the following steps:

[0032] Step S10, the MME receives the user subscription data, and identifies the indication information about the user's security function from it;

[0033] Step S20, the MME configures the algorithm list according to the indication information; and

[0034] In step S30, an algorithm is selected according to the algorithm list and predetermined conditions, and the selected algorithm is used to perform security functions on the user. The predetermined conditions include security algorithms supported by the UE and security algorithms supported by the MME or eNB itself.

[0035] The MME or eNB in ​​the prior art selects an algorithm according to three conditions. 1. Security algori...

Abstract

The invention provides a security function control method and a system thereof. The method comprises the following steps: an MME receives subscriber profile and distinguishes indicating information about security function of users; the MME configures an algorithm list according to the indicating information; security function is carried out to users by a selected algorithm selected according to the algorithm list and the presetting condition and the presetting condition comprises a security algorithm supported by UE or a security algorithm supported by eNB. The method and the system of the invention can encrypt a user plane as a service to provide to users needing the service and the invention also provides a mode for user monitoring, which richens service choices of operators.

Description

technical field [0001] The present invention relates to the communication field, in particular to a safety function control method and system. Background technique [0002] Such as figure 1 As shown, the 3GPP Evolved Packet System (EPS for short) is composed of an Evolved UMTS Terrestrial Radio Access Network (EUTRAN for short) and an EPS core network (Evolved Packet Core, EPC for short). Among them, the EPS core network consists of a Mobility Management Entity (MME for short), a Serving Gateway (S-GW for short), a Packet Data Network Gateway (PDN GW for short), and a Home Subscriber Server (Home Subscriber Server). , referred to as HSS), and other supporting nodes. The interface between EUTRAN and MME is S1-MME, the interface between the service gateway and the service gateway is S1-U, the interface between the MME and the home user server is S6a, and the interface between the service gateway and the service gateway is S11. The interface between data network gateways is ...
