Problems solved by technology

However, in the existing solution, before the BSF and HSS update the GUSS, they do not check which contents of the USS have been modified by the NAF. As a result, the NAF has the absolute right to insert, update or delete the USS, and can make changes to the data in the USS. Arbitrary modification, so it may cause GUSS to be updated incorrectly

Embodiment Construction

[0039]In the present invention, when the NAF maintains (including inserts, updates, and deletes) the USS, after the BSF determines that the NAF has the legal identity to maintain the USS, it further judges whether the NAF has the right to operate according to the contents of the USS, and only for The content in the USS of the operation performs the described operation. Referring to the NAF maintenance USS flowchart of the present invention shown in FIG. 2 , it includes the following steps:

[0040] Step 201: After receiving a request from a NAF to maintain (update / delete / insert) the USS, the BSF judges whether the NAF has a legal identity to maintain the USS, if so, executes the next step, otherwise returns a response message to the NAF.

[0041] Step 202: The BSF determines which USS content the NAF needs to maintain, and determines whether the NAF has the corresponding authority for each content in turn, and only maintains the content of the USS with the authority. For the c...

Abstract

The invention relates to a method for maintaining USS, which comprises that: BSF receives the maintain request from NAF to maintain one USS; judges said legality of NAF; BSF checks the contents of maintained USS and finds out the USS content which can be operated by NAF, and operates the USS content; BSF sends operated USS to HSS, to store the USS of GUSS, and provide the system for maintaining USS. With said invention, NAF can correctly modify the USS of GUSS, to reduce HSS maintain load and support enough freedom to the NAF.

Description

technical field [0001] The invention relates to the technical field of 3GPP general authentication framework (GAA), in particular to a method and system for maintaining user security settings (USS). Background technique [0002] In the third-generation wireless communication standard, a Generic Authentication Architecture (GAA, Generic Authentication Architecture) is a general structure used by various application service entities to complete authentication of user identities. Checking and verifying the identity of users of application services can be realized through the general authentication framework. The various application services mentioned above may be multicast / broadcast services, user certificate services, instant information provision services, etc., or proxy services. [0003] Figure 1 shows the structure of the general authentication framework. The general authentication framework usually consists of user equipment (UE), entity (BSF) that performs initial chec...
